As shown in fig. 1, fig. 1 is a schematic structural diagram of an electronic device provided in an embodiment of the present application, where the electronic device includes: a

11 having an

111; a

12, at least partially disposed in the

111, having a display element array capable of outputting an image; wherein the

12 has at least a first state and a second state, and the occlusion parameters of the display area in the first state and the second state are different; the

13 is used for detecting a trigger parameter which can represent the state of the

12; the

14 is connected with the

12 and is used for controlling a first image to be displayed on a first display element set in the first state according to the trigger parameter; in the second state, controlling a second image to be displayed on a second set of display elements; wherein the first set of display elements and the second set of display elements are different. The

14 is connected with the

13 to acquire the trigger parameter.

The

12 has a plurality of

121 arranged in an array. The first set of display elements includes a plurality of

121 and the second set of display elements includes a plurality of

121. The

121 included in the first set of display elements are not identical to the

121 included in the second set of display elements.

According to the embodiment of the application, the electronic device can select the display element set matched with the shielding parameters in the state in the display element array to display the image based on the shielding parameters of the

12 in different states.

A

110 may be disposed in the

111 for exposing at least a portion of the display surface of the

12, and a transparent cover plate may be disposed on the

110 for sealing and protecting the internal components thereof. The

12 is a display screen, such as a Liquid Crystal Display (LCD) or an Organic Light Emitting Diode (OLED) display screen. The

121 is a pixel unit in a display screen. The control component is a controller and is used for controlling the display screen to display images.

In the manner shown in fig. 1, the

12 is a rigid display screen that is inflexible and has a flat panel configuration. In order to avoid light leakage at the edge of the

12, a part of the

121 disposed at the edge of the

12 is shielded by the

11, and as shown in fig. 1, a row of

121 is shielded by the

11 at each of the left and right ends. When there are other occluding objects on the display side of the electronic device, the occlusion parameters of the

12 may be different. According to the embodiment of the application, the electronic device can select the

121 to display the image through the

13 and the

14, so that the color display of the shielded and

121 is avoided, and the energy consumption can be at least reduced.

The occlusion parameters comprise an occlusion position and/or an occlusion magnitude. At least one end of the

12 may be arranged to be movable relative to the

11, and the first state and the second state are two states in which the array of display elements at the movable end of the

12 is occluded by the

11 in different positions and/or magnitudes, such that the two states have different occlusion parameters. In this way, movement of the end of the

12 relative to the

11 may be used to cause the

11 to have different shading parameters for the edges of the corresponding movable end of the array of display elements.

As shown in fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a display component in an electronic device provided in an embodiment of the present application in a first posture, fig. 3 is a schematic structural diagram of a display component in an electronic device provided in an embodiment of the present application in a second posture, and the

12 is a display component having a deformation capability at least in a

23, where the deformation capability is a capability of changing a relative angle between a

21 and a

22 on two sides of the

23. Fig. 2 and 3 only show the structure of the

12 and its configuration in the first posture and the second posture, and do not show the structures of the

11, the

13 and the

14, which can refer to the manner shown in the figures and are not described again here.

The

12 may be a flexible display screen, such as an OLED display screen. At least the

23 of the

12 having the deformation capability can bend along with the bending of the

11, so as to change the relative angle of the

21 and the

22. The

12 may be configured to be flexible and bendable as a whole, such that the

12 can be bent and/or folded only at predetermined local positions corresponding to the axis based on the

11 or other supporting structure.

Wherein the

21 and the

22 are switchable between a first posture and a second posture by changing the relative angle. In the first posture, the display surface of the

21 and the display surface of the

22 satisfy a relative condition, that is, the display surfaces of the

21 and the

22 are parallel and opposite or approximately parallel and opposite to each other, and the display surfaces thereof are opposite to each other and have an included angle not exceeding a first included angle, which is determined based on a support member such as a housing, and may be 30 degrees or 10 degrees, for example. In the second posture, the display surface of the

21 and the display surface of the

22 satisfy a planar condition, that is, the display surfaces of the

21 and the

21 are located on a plane or approximately on a plane, and an angle between the two display surfaces does not exceed a second included angle and is not smaller than a third included angle, the second/third included angle is determined based on a support component such as a housing, and the second included angle may be 185 degrees, 180 degrees or 190 degrees, for example; the third included angle may be 175 degrees or 170 degrees.

The end of the

21 remote from the

22 and/or the end of the

22 remote from the

21 is movable relative to the

11 to support the

21 and the

22 at different angles. The

12 has an end portion which is movable relative to the

11 such that the

23 can flex with bending of the

11 to change the relative angle between the display surfaces of the first and

21, 22 and also to avoid excessive stretch breaking of the

12.

When the

12 is switched between the first posture and the second posture, the electronic device is bent, since the

12 has an end portion movable relative to the

11, the shielding parameters of the

12 at the edge of the display element array corresponding to the movable end portion are changed, and the display surface of the

21 and the display surface of the

22 have different relative angles and different shielding parameters. The electronic device can select the

121 to perform color display through the

13 and the

14, so that the color display of the

121 is avoided, and the energy consumption can be at least reduced.

The

13 comprises an angle detection assembly disposed at the

12 and/or the

11 for detecting a trigger parameter indicative of the relative angle of the

21 and the

22.

The angle detection component is an angle sensor for detecting the relative angle of the

21 and the

22, or a gyroscope, a position sensor or other sensor capable of detecting the relative position to characterize the relative angle. Different relative positions represent different angular gears.

The

11 includes a first support for opposing the

21 and a second support for opposing the

22, and the first support and the second support have a rotation axis therebetween, so that the first support and the second support can rotate relatively, thereby changing a relative angle of the

21 and the

22 based on the rotation of the first support and the second support. The angle detection component may be disposed on the rotating shaft, or disposed on the

12, or disposed on the rotating shaft and the

12, respectively, to obtain the trigger parameter representing the relative angle.

Wherein the

14 is configured to determine the occlusion parameter for the display element array of the movable end of the display component array being occluded by the

11 according to the trigger parameter, determine the first set of display elements in the first state, or determine the second set of display elements in the second state.

Further, the

14 may be further configured to determine the occlusion parameter for the display element array at the movable end of the display element array being occluded by the

11 according to the trigger parameter, determine the first display element set and the first image in the first state, or determine the second display element set and the second image in the second state.

Different trigger parameters correspond to different states and occlusion parameters, and different states of the

12 have different occlusion parameters. In the above embodiments, the trigger parameter characterizing the relative angle is used to determine the set of display elements of the display element array in different states, and based on this, the image display is performed to display the image.

When the angle is different, the shielding parameters are different, so that the triggering parameters and the shielding parameters have corresponding relations. Therefore, the

14 can read the occlusion parameter corresponding to the current trigger parameter from the pre-stored correspondence set based on the current trigger parameter according to the pre-stored correspondence set to determine the current display element set, so as to select the

121 corresponding to the display element set from the display element array for color display. In this case, it is set that the electronic device further includes a memory connected to the

14, and the memory stores the correspondence set. The

14 may also calculate the occlusion parameter based on the current trigger parameter based on the correspondence of the relative angle to the occlusion parameter to determine the current set of display elements.

In the embodiment of the present application, it may also be determined whether the

121 is occluded based on the target current of the

121, so as to determine that the current display element set is used for image display, and turn off the

121. At this time, the structure of the electronic device is as shown in fig. 4.

As shown in fig. 4, fig. 4 is a schematic structural diagram of another electronic device provided in this embodiment of the present application, in this manner, the detecting

13 includes a current detecting component array disposed corresponding to the display element array, and is configured to detect a set of target currents corresponding to the

121, where the target currents are generated by the current detecting

131 after being irradiated by light rays meeting a first condition; the

14 is configured to determine the occlusion parameter in the first state to determine the first set of display elements in the first state or to determine the occlusion parameter in the second state to determine the second set of display elements in the second state based on the target set of currents. The

13 has a plurality of

131 connected to the

121 in a one-to-one correspondence. Based on the obtained set of target currents, a position of a display element in the circuit that generates the target current pair can be determined, and thus a position of the display element of the target current pair can be determined to determine a set of currently non-occluded display elements, and thus a current occlusion parameter.

As shown in fig. 5a, fig. 5a is a schematic structural diagram of another electronic device provided in an embodiment of the present application, and based on the above embodiment, in the manner shown in fig. 5a, the

11 includes a

112 and a

113 at edges of the device, the

111 is provided between the

112 and the

113, the

112 is on a side of a display surface of the

12, and the

113 is on an opposite side of the display surface of the

12; the detecting assembly includes a

132 disposed between the

112 and the

12 for making the current detecting assembly array obtain the detecting light satisfying the first condition. The detection light of the first condition can excite the

131 to generate a target current that can be detected. In the embodiment of the present application, the

132 may be an infrared light source device or an ultraviolet light device.

The

132 and the

131 are both connected to the

14 to operate under the control of the

14. The current detecting

131 is further configured to control color display of the

121. The

131 may be a pixel Thin Film Transistor (TFT), for example, an existing pixel thin film transistor of the

121 may be multiplexed as the

131, and the determination of the shielding parameter may be achieved based on the inherent element in the

12 without separately providing the current detection component. The

131 in the same column in fig. 4 are connected to the

14 through the same signal line. The rows and columns are different in relative direction, in which case the

131 in the same row may be connected to the

14 via the same signal line. The

131 in the same row or column are used for detecting simultaneously, so that the determined display element sets are in the whole row and the whole column, and the regular order of the displayed images is ensured. The signal line may be a data signal line, and is used not only to obtain the target current from the

131, but also to supply a data voltage to the

121 via the

131 to drive it to perform color display. The data signal lines for driving the

121 to perform color display are multiplexed to obtain the target current without separately adding signal lines.

The

132 is disposed below the

112, and the

132 can be controlled to emit detection light directly to the display element array/current detection element array in the area shielded by the

112, so as to enable the

131 corresponding to the shielded

121 to generate a target current, so that the position of the shielded

121 can be determined based on the obtained target current, and further determine a shielding parameter. The

132 may also emit a detection light toward the

112, and the detection light is reflected by the

112 opposite to the display surface of the

12 and then irradiates the

131 corresponding to the blocked

121 to generate a target current, so that the position of the blocked

121 can be determined based on the obtained target current, and thus the blocking parameter can be determined. In this manner, in order to avoid the absorption of the detection light by the

112, which results in that the intensity of the reflected detection light is not enough to enable the

131 to generate the target current or the generated target current is less and inconvenient to detect, a reflective coating may be disposed on the sidewall of the

112 to reduce the absorption of the detection light, so as to improve the reflection of the detection light.

In the manner shown in fig. 5a, the

132 can enable the detection

131 to generate a target current, so as to determine the shielded display element set. The display device can detect the shielding parameters in real time in the using process of a user so as to select the display element set which is adapted under the current display posture to display the image.

The display device shown in fig. 5a may also be used as calibration equipment before the display device leaves the factory in other embodiments of the present application. Based on the display device shown in fig. 5a, the corresponding shielding parameters in different states (i.e., different trigger parameters) of the first part and the second part of the

12 with different relative angles can be obtained, and the corresponding relationship set including the different angles and the corresponding shielding parameters thereof is stored in the embodiment of the display device without the light-emitting element, so that a user can detect the trigger parameters representing the relative angle degree through the angle detection component of the display device, and can obtain the current shielding parameter based on the parameters and the corresponding relationship set, and at this time, the light-emitting element does not need to be configured separately for the display device after leaving the factory.

At the end of the

12 that is movable relative to the

112, the

132 may be arranged as shown in fig. 5 b.

As shown in fig. 5b, fig. 5b is a schematic diagram of a layout principle of light emitting elements according to an embodiment of the present application, and when the

12 satisfies a planar state, the

12 is at least at the left end, which is an end portion movable relative to the

112. Between the end and the

112 is a

132.

As shown in the upper diagram of fig. 5b, the detection light emitted from the

132 can be set to irradiate the area covered by the

112 at the end portion, and the area covered by the

112 can be irradiated with the detection light no matter how the end portion moves relative to the casing, so that it can be directly determined that the

121 in the irradiation area is shielded by the

112, and thus, the shielding parameter can be determined.

As shown in the lower diagram of fig. 5b, the detecting light emitted from the light emitting element 123 can be irradiated to the boundary line region inside the

112 at the end portion, no matter how the end portion moves relative to the

11, the boundary line region between the blocked region of the

112 and the unblocked region on the

12 can be determined, and the blocked

121 can be determined based on the boundary line, so as to determine the blocking parameter.

The

132 is turned on based on the control of the

14, so that the waste of electric energy caused by long-time turning on of the

132 is avoided.

The

12 includes at least a

21 and a

22 whose relative angles are changeable. The

13 comprises an angle detection component arranged on the display component and/or the shell and used for detecting a trigger parameter for representing the relative angle of the first part and the second part; if the trigger parameter indicates that the relative angle satisfies the second condition, the

14 controls the light-emitting

132 to be turned on. The second condition is that the relative angle is at a specific angle, such as 0 degrees, 90 degrees, 180 degrees, and the detection is turned on at the specific angle, and the occlusion detection can be performed based on the specific posture of the display device. Or the second condition is that the change value of the relative angle is greater than the set angle, the angle can be 10 degrees, 15 degrees and the like, and based on the change value of the relative angle, the detection can be started when the change of the shielding parameter of the display device meets the detection requirement at the relative angle. The relative angle is 0 degree when the

21 and the

22 satisfy the relative condition, and 180 degrees when the plane condition is satisfied. The

14 turns on the angle detection element for a set period of time to detect the trigger parameter. The display device is large in folding amplitude, capable of achieving large position change and large in shielding parameter change, and based on the opening detection, the display device can enable the display element to be integrated and shielding parameter to be adaptive, and display effect is guaranteed.

The

14 may be configured to control the

132 to turn off after a set period of time, for example, turn on for 1 s. Or setting that the light-emitting

132 is turned off after the gesture switching is completed, and obtaining the trigger parameter and the shielding parameter in the current gesture after the gesture switching is completed, so as to be used for determining the currently displayed display element set, and at this time, if the gesture of the

12 does not change within a set time, controlling the light-emitting

132 to be turned off, where the set time may be 5s or 10 s.

In other ways, if the power of the

12 increases to satisfy the third condition, the

14 controls the

132 to turn on. The third condition includes that the power of the

12 is increased by not less than a set threshold, such as the display assembly is switched from a standby state to an illuminated state. When the electronic device is switched from the standby state to the lighting state, the current posture of the display device needs to be confirmed, so that the display element set is confirmed to display images based on the shielding parameters of the current posture, and therefore detection needs to be started.

The electronic device includes: the sensing assembly is overlapped with the display assembly and is used for sensing the approaching and/or contact operation of the operation body; the sensing component is a touch electrode component, which enables the

12 to respond to the proximity and/or contact operation of the sensing operation body so as to execute corresponding functions.

In one mode, the

14 can determine, based on the occlusion parameter, a portion of the array of display elements to be displayed as a current set of display elements to form a current image, where the current image is a portion of the image to be displayed. In this manner, the portion of the display element array that is shielded does not emit light and image display is not possible, and a portion of the image to be displayed is displayed by displaying the image in the portion that is not shielded (the current display element set). This method is equivalent to cutting off the image portion to be displayed and displaying only the partial image. In this way, if the target operation object or the operation area in the first image and the second image is completely located in the display area corresponding to the blocked display element, the position of the target operation object or the operation area needs to be adjusted, and the target operation object or the operation area is displayed by the non-blocked display element array. And translating the position of the target operation object or the operation area without changing the display scale of the target operation object or the operation area.

In another way, the

14 can determine, based on the occlusion parameter, that a portion of the display element array is displayed as a current display element set image, and form a current image, where the current image is a reduced image of the image to be displayed. In this way, the blocked portion of the display element array does not emit light, image display cannot be performed, and image display is performed by the unblocked portion (current display element set), and the light emitting parameters of the unblocked

121 in the image to be displayed and the current image are different. The current image and the image to be displayed have the same displayed image content and different image sizes, so that the target operation object or the operation area is always at least partially displayed by the non-shielded display element. The mode is different from the existing mode that a plurality of background application display interfaces are overlapped and reduced by an existing smart phone so that a user can conveniently perform scaling display of application switching.

12, the

12 can be switched from the first state to the second state, and switching of the display state is achieved based on different shielding parameters. At this time, the first state is a state where the electronic apparatus has not placed the accessory apparatus, and the second state is a state where the electronic apparatus has placed the accessory apparatus. Fig. 6 merely shows the electrical connection relationship of each electronic component in the electronic device, and does not show the relevant mechanical structure of the housing and the like.

31 is placed on the display side of the

12, and since the

31 blocks part of the display area of the

12, the blocking parameter changes, and the state of the

12 changes.

21 and the second portion of the

12 have a predetermined relative angle, and they are bent toward the display side, and can be used as a notebook. The

31, so as to enable the electronic device to determine a corresponding circle of display elements based on the circle of light-emitting elements, and determine an occlusion parameter based on the change of the circle of display elements and the trigger parameter of the display elements within the circle range; alternatively, the light emitting elements are arranged on the entire back surface of the
