The adjusting device 210 may be used to adjust the folding angle of the flexible folding display panel 100, so as to implement a polymorphic change of the flexible folding display panel 100.

The flexible folding display panel 100 includes at least two planar portions 110 and at least one bendable portion 120, and one bendable portion 120 is connected between the two planar portions 110. Fig. 2 is a schematic view of three planar portions 110 and two bendable portions 120, and it is understood that the present disclosure is not limited to the number of planar portions 110 and bendable portions 120, and may be configured according to actual display screen requirements, for example.

The adjustment device 210 is mounted to the back side of the display side of the flexible folded display panel 100. The adjusting means 210 is used to adjust the angle between the two planar portions 110 to which the bendable portion 120 is connected. Fig. 2 is illustrated with two adjustment devices 210, it being understood that the present disclosure is not limited to the number of adjustment devices 210, and may be configured according to actual angular adjustment requirements, for example.

According to the display assembly 200 provided by some embodiments of the present disclosure, the adjusting device 210 is installed on the back side of the display side of the flexible folding display panel 100, and the angle between the two planar portions 110 of the flexible folding display panel 100 is adjusted by the adjusting device 210, so that the multi-form variation of the flexible folding display panel 100 can be realized, when the display assembly 200 is used for vehicle-mounted display, the multi-form auxiliary driving experience can be provided for a driver, and meanwhile, an intelligent interaction view angle more suitable for the driving style of the driver is found for the driver, so that the user viewing experience is better; moreover, since the angle between the two planar portions 110 of the flexible folding display panel 100 of the present disclosure can be adjusted by the adjusting device 210 when the external environment changes, the reflected light is reduced, and the effect of eliminating shadows is achieved, so that the user is not easy to feel dazzling when watching, and the watching effect of the viewer is improved.

In some embodiments, with continued reference to fig. 2, the two planar portions 110 to which the bendable portion 120 is connected are a first planar portion 111 and a second planar portion 112, respectively.

The adjusting device 210 includes: a fixed frame 221, a rotating member 222, a connecting rod 223, a moving member 224, a guide rail 225, and a power source 226.

The holder 211 is mounted on the back side of the display side of the first planar portion 111. The rotating member 222 is rotatably installed on the fixing frame 221. One end of the connecting rod 223 is fixedly connected with the rotation member 222. The moving member 224 is hinged to the other end of the link 223. The guide rail 225 is mounted on the back side of the second plane portion 112 on the display side.

Under the drive of the power source 226, the rotating member 222 can rotate clockwise or anticlockwise, and the moving member 224 moves in the extending direction of the guide rail 225 under the drive of the connecting rod 223, so that the second plane portion 112 is driven to rotate clockwise or anticlockwise, and the angle of the second plane portion 112 relative to the first plane portion 111 is adjusted, so that the multi-form change of the flexible folding display panel 100 is realized, the multi-form auxiliary driving experience is provided for a driver, meanwhile, an intelligent interaction view angle more suitable for the driving style of the driver is found for the driver, and the user viewing experience is better.

In some embodiments, the mover 224 is a slider or a roller. The sliding block or the roller can be slidably connected with the guide rail 225, so that friction force between the moving member 224 and the guide rail 225 can be reduced, and relative movement between the moving member 224 and the guide rail 225 is easier.

In some embodiments, referring to fig. 2, the number of the second planar portions 112 is two, the two second planar portions 112 are located at two sides of the first planar portion 111, and the two second planar portions 112 are connected to the first planar portion 111 through one bendable portion 120, respectively.

The number of the adjusting devices 210 is two, and one adjusting device 210 is used for adjusting the angle of one second plane part 112 relative to the first plane part 111.

When the number of second flat portions 112 is two, the angle of one second flat portion 112 with respect to the first flat portion 111 may be the same as or different from the angle of the other second flat portion 112 with respect to the first flat portion 111.

For example, taking fig. 2 as an example, when the second plane portion 112 on the left side is driven by the adjusting device 210 to rotate 30 ° or 60 ° clockwise, the angle of the second plane portion 112 on the right side relative to the first plane portion 111 is 0 °, and at this time, the flexible folding display panel 100 is in the L-shaped display form as a whole. When the two second plane parts 112 are driven by the adjusting device 210 to rotate 30 ° or 60 ° clockwise, the flexible folding display panel 100 is in the S-display mode as a whole.

In this example, the number of the second plane parts 112 is two, and the number of the adjusting devices 210 is two, so that one adjusting device 210 can adjust the angle of one second plane part 112 relative to the first plane part 111, thereby realizing the multi-form variation of the flexible folding display panel 100 and providing the multi-form auxiliary driving experience for the driver.

In some embodiments, two adjustment devices 210 reuse one power source 226, at which time the display assembly 200 also includes a power switching device. The power switching device is used for controlling the power source 226 to be connected with any one of the two rotating members 222. Thus, the structure of the display assembly 200 can be simplified, and cost can be saved.

In some embodiments, referring still to fig. 2, two adjustment devices 210 multiplex one mount 221. Thus, it is possible to realize a multi-modal variation of the flexible folding display panel 100 and to simplify the structure of the display assembly 200.

In some embodiments, referring to fig. 2, one end of the flip chip film 20 is electrically connected to the main control circuit board 19, and the other end is bound to an edge of the second plane portion 112 away from the first plane portion 111. At this time, the display assembly 200 further includes a supporter 230. The supporting member 230 is mounted on the back side of the display side of the second plane portion 112, and the supporting member 112 is used for supporting the main control circuit board 19.

In some embodiments, referring to fig. 2, the display assembly 200 further includes a thermal insulation layer 231 disposed between the main control circuit board 19 and the support 230. Therefore, the main control circuit board 19 and the supporting member 230 can be bonded through the heat insulation adhesive layer 231, and heat generated by the adjusting device 210 in the moving process can be prevented from affecting the display effect of the flexible folding display panel 100.

For example, the heat-insulating adhesive layer 231 may be an ultraviolet-curable transparent adhesive layer, which is polymerized and crosslinked under the irradiation of ultraviolet light to be converted from a liquid state into a solid layer, and may be disposed on one side of the main control circuit board 19 by coating, printing, etc., and may be firmly attached to one side of the support 230 far from the flexible folding display panel 100, without other fixing structures, so as to simplify the installation.

In some embodiments, referring to fig. 2, the support member 230 has an L-shape, and a cavity is formed between the support member 230 and the second plane portion 112, and the moving member 224 corresponding to the second plane portion 112 can move into the cavity. Therefore, the structure of the display assembly 200 is more compact, and the moving member 224 can move into the cavity formed between the supporting member 230 and the second plane portion 112, so that the moving member can be ensured not to deviate to a certain extent, and the whole structure of the display assembly 200 is more stable.

In some embodiments, referring to fig. 3, fig. 3 is a partial detail structure diagram of the display assembly 200, and an opening pattern 131 is disposed on the supporting layer 13 of the flexible foldable display panel 100, and an orthographic projection of the opening pattern 131 on the flexible foldable display panel 100 is at least located at the bendable portion 120.

The opening pattern 131 may be one opening or a plurality of openings arranged in an array, and the shape of the plurality of openings may be any one of a rectangle, a semicircle, a semi-ellipse, a trapezoid, and a triangle, and of course, the shape of the plurality of openings may be other irregular shapes.

In this embodiment, by providing the opening pattern 131 at least at the position of the supporting layer 13 at the bendable portion 120, the bending stress of the flexible foldable display panel 100 at the bendable portion 120 can be reduced, and the bending and folding performance of the flexible foldable display panel 100 can be improved.

On the basis of this, for example, referring to fig. 3, the front projection of the opening pattern 131 on the flexible folding display panel 100 is also located in the area d of the planar portion 110 near the bendable portion 120. That is, the opening pattern 131 includes a portion located in the bendable portion 120 and a portion located in the region d of the planar portion 110 beyond the bendable portion 120.

The display assembly 200 provided in some embodiments of the present disclosure, by providing the opening pattern 131 on the support layer 13 of the flexible folding display panel 100, and the opening pattern 131 includes a portion located in the bendable portion 120 and a portion located in the region d of the planar portion 110 beyond the bendable portion 120, enables better bending performance of the bendable portion 120 of the flexible folding display panel 100, thereby enabling easier adjustment of the angle between the two planar portions 110 to which the bendable portion 120 is connected, of the display assembly 200.

In some examples, the direction pointed by the bendable portion 120 toward the planar portion 110 is a first direction; the dimension d of the area of the planar portion 110 adjacent to the bendable portion 120 in the first direction is 2mm to 10mm. For example, it may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or the like.

In this example, when the dimension d of the area of the planar portion 110 near the bendable portion 120 in the first direction is equal to or approaching 2mm, the bending performance of the flexible folding display panel 100 at the bendable portion 120 can be improved to some extent while making the arrangement area of the opening pattern 131 smaller, the support layer 13 better serves to support the flexible folding display panel 100, so that the overall structural strength of the flexible folding display panel 100 is higher. When the dimension d of the area of the plane portion 110, which is close to the bendable portion 120, in the first direction is equal to or approximately equal to 10mm, the bending performance of the flexible foldable display panel 100 in the bendable portion 120 can be greatly improved, and the flexible foldable display panel 100 can be supported to a certain extent because the arrangement area of the opening pattern 131 is not excessively large, so that the overall structural strength of the flexible foldable display panel 100 is ensured.

In some embodiments, the display assembly 200 further includes a scratch-resistant tape 132. The scratch-proof tape 132 covers the opening pattern 131.

The scratch-proof tape 132 may be, for example, a mailer tape. The Mylar tape is also called a polyester tape, takes a polyester film as a base material and takes an acrylic acid flame retardant adhesive as an adhesive, and the product has high shape property, excellent chemical resistance, chemical resistance and moisture resistance, and can resist cutting and abrasion.

Referring to fig. 7, some embodiments of the present disclosure further provide a display control method applied to the display assembly 200 provided in the above embodiments. The display control method comprises the following steps: S1-S2.

S1: the intensity of light directed to at least one set location of the flexible folded display panel 100 is obtained.

In this step, the "at least one position" may refer to one position shown in fig. 4 or 5, i.e., the position where the photosensor 301 is located; alternatively, there may be a plurality of positions, and the plurality of positions may be uniformly distributed, and each position may be provided with the photosensitive sensor 301.

S2: based on the obtained light intensity, the at least one adjusting means 210 is controlled to adjust the relative angle of the at least two planar portions 110.

In this step, an adjustment device adjusts the angle of a second planar portion 112 with respect to the first planar portion 111, for example as described in the foregoing fig. 2, which may range from 0 ° to 180 °, here being the maximum achievable value.

It should be noted that, controlling the at least one adjusting device 210 to adjust the relative angle of the at least two planar portions 110 may be that a control device is disposed in the display assembly 200, and based on the obtained light intensity, the control device controls the relative angle of the at least two planar portions 110 of the flexible foldable display panel 100; the relative angles of the at least two planar portions 110 of the flexible folding display panel 100 may also be manually controlled based on the acquired light intensity through the interactive interface of the flexible folding display panel 100.

In this embodiment, by acquiring the light intensity of at least one set position of the flexible foldable display panel 100, and based on the acquired light intensity, controlling the adjusting device 210 to adjust the relative angle of at least two planar portions 110, a multi-modal variation of the flexible foldable display panel 100 can be achieved, and when the display assembly 200 is used for vehicle-mounted display, a multi-modal auxiliary driving experience can be provided for a driver, and meanwhile, an intelligent interaction viewing angle more suitable for the driving style of the driver is found for the driver, so that the multi-modal auxiliary driving experience has better user viewing experience; moreover, since the angle between the two planar portions 110 of the flexible folding display panel 100 of the present disclosure can be adjusted by the adjusting device 210 when the external environment changes, the effect of eliminating shadows is achieved by reducing the reflected light, so that the user is not easy to feel dazzling when watching, and the watching effect of the viewer is improved.

In some embodiments, the display assembly 200 further comprises: and a light detection device 30. The light detecting device 30 is used for detecting the intensity of light directed to at least one set position of the flexible folding display panel 100.

The step of obtaining the intensity of the light emitted to at least one set position of the flexible foldable display panel 100 specifically includes:

The intensity of light directed to at least one set position of the flexible folding display panel 100 is acquired by the light detecting means 30.

In this embodiment, the light intensity of at least one set position of the flexible folding display panel 100 is obtained by the light detection device 30, and based on the light intensity, the relative angle of at least two planar portions 110 of the flexible folding display panel 100 is adjusted, so that the accuracy of angle adjustment can be ensured, and the problems of improper adjustment angle and poor viewing effect caused by artificial subjective judgment of the light intensity of the flexible folding display panel 100 are avoided.

In some embodiments, referring to fig. 2 and 8, in the case that two planar portions 110 to which the bendable portion 120 is connected are the first planar portion 111 and the second planar portion 112, respectively:

the step of controlling the at least one adjusting device 210 to adjust the relative angle of the at least two planar portions 110 based on the acquired light intensity includes S21 to S22.

S21: and determining the adjusting angle corresponding to the light intensity based on the detected light intensity and the corresponding relation between the light intensity and the adjusting angle.

S22: the adjustment device 210 is controlled to drive the second planar portion 112 to rotate by the determined adjustment angle with respect to the first planar portion 111.

The corresponding relation between the light intensity and the adjusting angle means that the adjusting angle corresponding to the light intensity exists for different measured illumination intensities. For example, different illumination intensities may correspond to different adjustment angles, respectively; alternatively, a set of illumination intensities (e.g., a plurality of illumination intensities within the same value range) may correspond to the same adjustment angle, that is, at this time, the plurality of sets of illumination intensities may respectively correspond to different adjustment angles.

In addition, the correspondence between the light intensity and the adjustment angle may be stored in the internal memory of the display assembly 200 in advance, or may be stored in the external memory coupled to the display assembly 200 in advance. The storage method in the case of storing the correspondence in advance is not limited here.

Through the display control method, different light intensities can be obtained, the adjusting angle corresponding to the light intensities can be determined according to the different light intensities, the accuracy of angle adjustment can be ensured, an intelligent interaction viewing angle which is more suitable for the driving style of a driver can be found for the driver, and better user viewing experience is achieved.

Based on this, in some embodiments, the light intensity is positively correlated with the adjustment angle. By the design, the adjusting angle determined by the rotation of the second plane part relative to the first plane part can be increased along with the increase of the light intensity, so that when the light intensity is large, the adjusting angle determined by the rotation of the second plane part relative to the first plane part is large, a proper intelligent interaction visual angle is provided for a driver, and better user watching experience is achieved.

In some embodiments, when the light intensity is greater than or equal to 0nit and less than or equal to 200nit, the adjustment angle corresponding to the light intensity is 0 degrees; when the light intensity is more than 200nit and less than or equal to 400nit, the adjusting angle corresponding to the light intensity is 15+/-5 degrees; when the light intensity is more than 400nit and less than or equal to 600nit, the adjusting angle corresponding to the light intensity is 30+/-5 degrees; and when the light intensity is greater than 600nit, the adjusting angle corresponding to the light intensity is 60+/-5 degrees.

When the light intensity is greater than 200nit and less than or equal to 400nit, the minimum value of the adjusting angle corresponding to the light intensity is, for example, 10 degrees, the maximum value is, for example, 20 degrees, and the median value is, for example, 15 degrees. When the light intensity is greater than 400nit and less than or equal to 600nit, the minimum value of the adjusting angle corresponding to the light intensity is 25 degrees, the maximum value is 35 degrees, and the median value is 30 degrees. When the light intensity is greater than 600nit, the minimum value of the adjusting angle corresponding to the light intensity is 55 degrees, the maximum value is 65 degrees, and the median value is 60 degrees.

In this embodiment, based on the detected different light intensities, the relative angles of the at least two planar portions 110 of the flexible folding display panel 100 are adjusted, so that the accuracy of angle adjustment can be ensured, and the problems of improper adjustment angle and poor viewing effect caused by manually and subjectively judging the light intensity of the light emitted to the flexible folding display panel 100 are avoided.
