下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

请参阅图1,图1为本申请实施例提供的电子设备处于展开状态的结构示意图。电子设备诸如图1的电子设备20可为计算设备诸如膝上型计算机、包含嵌入式计算机的计算机监视器、平板电脑、蜂窝电话、媒体播放器、或其他手持式或便携式电子设备、较小的设备(诸如腕表设备、挂式设备、耳机或听筒设备、被嵌入在眼镜中的设备或者佩戴在用户的头部上的其他设备,或其他可佩戴式或微型设备)、电视机、不包含嵌入式计算机的计算机显示器、游戏设备、导航设备、嵌入式系统(诸如其中具有显示器的电子设备被安装在信息亭或汽车中的系统)、实现这些设备中的两个或更多个设备的功能的设备、或其他电子设备。在图1的示例性配置中,电子设备20是便携式设备,诸如蜂窝电话、媒体播放器、平板电脑、或者其他便携式计算设备。如果需要,其他配置可用于电子设备20。图1的示例仅是示例性的。Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of an electronic device in an unfolded state according to an embodiment of the present application. An electronic device such as electronic device 20 of FIG. 1 may be a computing device such as a laptop computer, a computer monitor including an embedded computer, a tablet computer, a cell phone, a media player, or other hand-held or portable electronic device, smaller Devices (such as wristwatch devices, hanging devices, earphone or earpiece devices, devices embedded in eyeglasses or other devices worn on the user's head, or other wearable or miniature devices), televisions, excluding Computer monitors for embedded computers, gaming devices, navigation devices, embedded systems (such as systems in which electronic devices with displays are installed in kiosks or cars), implementing the functions of two or more of these devices equipment, or other electronic equipment. In the exemplary configuration of FIG. 1, electronic device 20 is a portable device, such as a cellular telephone, media player, tablet computer, or other portable computing device. Other configurations may be used for electronic device 20 if desired. The example of FIG. 1 is exemplary only.

如图1所示,诸如上述的电子设备20可以配置为可折叠的设备。可折叠的设备包括可折叠显示屏,诸如图1所示的可折叠显示屏200。可折叠显示屏200可以采用柔性OLED(Organic Light Emitting Diode,有机发光二极管)显示屏,柔性液晶显示屏(LiquidCrystal Display,LCD)、或其他类型的可折叠显示屏。可折叠显示屏200用于显示画面。可折叠显示屏200可以为规则形状,比如长方体结构、圆角矩形结构,可折叠显示屏200也可以为不规则的形状。As shown in FIG. 1, an electronic device 20 such as described above may be configured as a foldable device. A foldable device includes a foldable display, such as foldable display 200 shown in FIG. 1 . The foldable display screen 200 may adopt a flexible OLED (Organic Light Emitting Diode, organic light emitting diode) display screen, a flexible liquid crystal display (Liquid Crystal Display, LCD), or other types of foldable display screens. The foldable display screen 200 is used for displaying pictures. The foldable display screen 200 may have a regular shape, such as a rectangular parallelepiped structure and a rounded rectangular structure, and the foldable display screen 200 may also have an irregular shape.

例如,请参阅图1和图2,图2为本申请实施例提供的电子设备处于折叠状态的结构示意图,电子设备20包括可弯折部分和不可弯折部分。诸如可弯折部分连接在两个不可弯折部分之间,且两个不可弯折部分可通过可弯折部分进行弯折,以实现电子设备20弯折状态和展开状态之间的切换。这样,当电子设备20处于折叠状态时(如图2所示),可以使得电子设备20的占用空间较小,从而便于电子设备20的携带与存放;当电子设备20处于展开状态时(如图1所示),可以使得电子设备20具有较大的显示面积,从而便于用户对电子设备20的操作及阅读。需要说明的是,电子设备20的可弯折部分可具有一个弯折方向,即该弯折区可单向弯折;电子设备20的可弯折部分可具有两个弯折方向,即该弯折区可双向弯折。For example, please refer to FIG. 1 and FIG. 2. FIG. 2 is a schematic structural diagram of an electronic device in a folded state according to an embodiment of the present application. The electronic device 20 includes a bendable portion and a non-bendable portion. For example, the bendable portion is connected between the two non-bendable portions, and the two non-bendable portions can be bent by the bendable portion, so as to realize the switch between the bent state and the unfolded state of the electronic device 20 . In this way, when the electronic device 20 is in the folded state (as shown in FIG. 2 ), the occupied space of the electronic device 20 can be made smaller, thereby facilitating the carrying and storage of the electronic device 20; when the electronic device 20 is in the unfolded state (as shown in FIG. 2 ) 1), the electronic device 20 can be made to have a larger display area, thereby facilitating the user to operate and read the electronic device 20. It should be noted that the bendable portion of the electronic device 20 may have one bending direction, that is, the bending region may be bent in one direction; the bendable portion of the electronic device 20 may have two bending directions, that is, the bending region The folding area can be bent in both directions.

在一些相关技术中,通常在可折叠显示屏的表面设置一层有机高分子保护层比如聚酰亚胺高分子保护层,虽然有机高分子保护层易于折叠,但是其硬度较低,抗冲击能力差,当其与金属物件或其他较硬的物体相互碰撞时,容易损坏保护层,而在可折叠显示屏的显示面留下划痕,影响用户的使用体验。In some related technologies, an organic polymer protective layer such as a polyimide polymer protective layer is usually arranged on the surface of the foldable display screen. Although the organic polymer protective layer is easy to fold, its hardness is low and its impact resistance is low. Poor, when it collides with metal objects or other hard objects, it is easy to damage the protective layer, leaving scratches on the display surface of the foldable display, which affects the user experience.

基于相关技术中出现的缺陷,本申请实施例提供一种可折叠显示屏,诸如图3所示的可折叠显示屏200,图3为图1所示电子设备中可折叠显示屏的结构示意图。可折叠显示屏200可包括柔性显示面板210,柔性显示面板210可以包括显示基板和封装材料,显示基板和封装材料中间封装有机发光物;显示基板和封装材料中间也可以封装有液晶材料,电子设备20的主板为液晶材料提供电压,从而改变液晶分子的排列方向,背光模组投射出的光经由显示面板内部共同作用后,在显示区域形成图像,以显示画面。柔性显示面板210可以包括显示面和非显示面,柔性显示面板210的显示面和柔性显示面板210的非显示面可以相背设置。Based on the defects in the related art, an embodiment of the present application provides a foldable display screen, such as the foldable display screen 200 shown in FIG. 3 , which is a schematic structural diagram of the foldable display screen in the electronic device shown in FIG. 1 . The foldable display screen 200 may include a flexible display panel 210, and the flexible display panel 210 may include a display substrate and an encapsulation material, and an organic light-emitting substance is encapsulated between the display substrate and the encapsulation material; a liquid crystal material may also be encapsulated between the display substrate and the encapsulation material, and the electronic device The main board of 20 provides voltage for the liquid crystal material, thereby changing the alignment direction of the liquid crystal molecules. After the light projected by the backlight module interacts through the display panel, an image is formed in the display area to display the picture. The flexible display panel 210 may include a display surface and a non-display surface, and the display surface of the flexible display panel 210 and the non-display surface of the flexible display panel 210 may be disposed opposite to each other.

可折叠显示屏200还可以包括玻璃层,诸如玻璃层220,玻璃层220可以层叠设置在柔性显示面板210的显示面。玻璃层220可为单层结构,玻璃层220也可以为多层结构,比如玻璃层220可以包括两个层叠设置的子层,或三个层叠设置的子层,或其他数量的子层等。The foldable display screen 200 may further include a glass layer, such as the glass layer 220 , and the glass layer 220 may be stacked on the display surface of the flexible display panel 210 . The glass layer 220 may be a single-layer structure, and the glass layer 220 may also be a multi-layer structure. For example, the glass layer 220 may include two stacked sublayers, or three stacked sublayers, or other numbers of sublayers.

玻璃层220可以包括一个或多个可弯折部分和一个或多个不可弯折部分,可弯折部分与不可弯折部分相连,其中可弯折部分与电子设备20的可弯折部分对应设置,玻璃层220的不可弯折部分与电子设备20的不可弯折部分对应设置,本申请实施例以一个可弯折部分和两个不可弯折部分为例进行说明。The glass layer 220 may include one or more bendable parts and one or more non-bendable parts, the bendable parts are connected with the non-bendable parts, wherein the bendable parts are arranged corresponding to the bendable parts of the electronic device 20 , the non-bendable part of the glass layer 220 is set corresponding to the non-bendable part of the electronic device 20 , and the embodiment of the present application is described by taking one bendable part and two non-bendable parts as an example.

结合图4至图8所示,图4为图2所示可折叠显示屏中玻璃层的第一种结构示意图,图5为图2所示可折叠显示屏中玻璃层的第二种结构示意图,图6为图5所示玻璃层中第一子层的结构示意图,图7为图2所示可折叠显示屏中玻璃层的第三种结构示意图,图8为图7所示玻璃层中第二子层的结构示意图。玻璃层220包括一个可弯折部分,玻璃层220在可弯折部分设置在多个空隙,诸如空隙222,空隙222位于玻璃层220内部,以使得从玻璃层220的外表观察不到空隙222。比如当玻璃层220为单层结构时,可以在玻璃层220的厚度方向上开设一个或多个通孔以形成空隙222;当玻璃层220为多层结构时,可以在子层开设一个或多个通槽以形成空隙222。。4 to 8 , FIG. 4 is a schematic diagram of the first structure of the glass layer in the foldable display screen shown in FIG. 2 , and FIG. 5 is a schematic diagram of the second structure of the glass layer in the foldable display screen shown in FIG. 2 6 is a schematic structural diagram of the first sublayer in the glass layer shown in FIG. 5 , FIG. 7 is a third structural schematic diagram of the glass layer in the foldable display screen shown in FIG. 2 , and FIG. 8 is a schematic diagram of the glass layer shown in FIG. 7 . Schematic diagram of the structure of the second sublayer. The glass layer 220 includes a bendable portion where the glass layer 220 is disposed in a plurality of voids, such as voids 222 , which are located inside the glass layer 220 such that the voids 222 are not visible from the exterior of the glass layer 220 . For example, when the glass layer 220 is a single-layer structure, one or more through holes can be opened in the thickness direction of the glass layer 220 to form the voids 222; when the glass layer 220 is a multi-layer structure, one or more through holes can be opened in the sublayer. through grooves to form voids 222 . .

空隙222可以为规则形状,比如空隙222为矩形结构、梯形结构等,空隙222也可以为不规则形状。空隙222可以减薄玻璃层220的可弯折部分厚度。这样,当玻璃层220的可弯折部分弯折时,空隙222可以吸收弯折时所产生的应力,不会对可折叠显示屏200的弯折活动造成限制。而且玻璃层220的不可弯折部分能够保护柔性显示面板210的表面,提高可折叠显示屏200的抗冲击能力,使得可折叠显示屏200不易受到损坏。从而实现了在不对可折叠显示屏200的弯折活动造成限制的前提下,提高可折叠显示屏200的抗冲击能力和表面耐刮性。The voids 222 may be of regular shape, for example, the voids 222 may have a rectangular structure, a trapezoidal structure, etc. The voids 222 may also be of irregular shapes. The voids 222 may reduce the thickness of the bendable portion of the glass layer 220 . In this way, when the bendable portion of the glass layer 220 is bent, the void 222 can absorb the stress generated during bending, and will not limit the bending activity of the foldable display screen 200 . In addition, the non-bendable portion of the glass layer 220 can protect the surface of the flexible display panel 210 and improve the impact resistance of the foldable display screen 200, so that the foldable display screen 200 is not easily damaged. Thus, the impact resistance and surface scratch resistance of the foldable display screen 200 can be improved without restricting the bending movement of the foldable display screen 200 .

此外,值的一提的是,本申请实施例所提供的电子设备20,在弯折后展开至平面状态时,由于玻璃层220的可弯折部分设置有空隙222,空隙222可比较彻底地释放玻璃层220在弯曲过程中产生的应力,从而使得展开后的玻璃层220中应力残留的较少,甚至没有应力残留,也就避免了玻璃层220弯折再展开后应力残留和积累的问题。可见,本申请实施例所提供的电子设备20,不仅在弯折状态下整个表面的平整度高,弯折活动不受限制,而且在弯折再展开后的状态下表面不会起拱,平整度同样较高,从而电子设备20在上述两种状态下的画面显示效果均较好。In addition, it is worth mentioning that, when the electronic device 20 provided by the embodiment of the present application is unfolded to a flat state after being bent, since the bendable portion of the glass layer 220 is provided with a gap 222, the gap 222 can be relatively completely The stress generated during the bending process of the glass layer 220 is released, so that less stress remains in the unfolded glass layer 220, or even no stress remains, thus avoiding the problem of stress residue and accumulation after the glass layer 220 is bent and then unfolded . It can be seen that the electronic device 20 provided by the embodiment of the present application not only has a high flatness of the entire surface in the bent state, and the bending movement is not restricted, but also the surface will not be arched in the state of being bent and then unfolded, and the surface is flat. The degree of display is also high, so that the screen display effect of the electronic device 20 in the above two states is better.

其中,空隙222的深度小于玻璃层220的厚度。空隙222的深度指的是空隙222在沿垂直于电子设备20的显示面的方向上的尺寸。空隙222的深度可以根据可弯折部分的弯曲弧度来设计。若可弯折部分的弯曲弧度较大,则可以将空隙222的深度设置得较大;若可弯折部分的弯曲弧度较小,则可以将空隙222的设置得较小。可以理解的是,可弯折部分的弯曲弧度越大,可弯折部分弯折时所产生的应力也就越大,此时将空隙222的深度设置得更大时可以吸收更多的应力。The depth of the void 222 is smaller than the thickness of the glass layer 220 . The depth of the void 222 refers to the dimension of the void 222 in a direction perpendicular to the display surface of the electronic device 20 . The depth of the void 222 can be designed according to the bending arc of the bendable portion. If the bending arc of the bendable portion is larger, the depth of the gap 222 may be set larger; if the bending arc of the bendable portion is smaller, the space 222 may be smaller. It can be understood that, the greater the bending arc of the bendable portion, the greater the stress generated when the bendable portion is bent. At this time, when the depth of the gap 222 is set larger, more stress can be absorbed.

空隙222的截面形状可以为梯形结构,空隙222的内侧壁面可以为平面结构。本申请实施例中所述的空隙222的截面形状是指垂直于可弯折部分的长度延伸方向且垂直于电子设备20的显示面方向对空隙222截断后所获得的截面形状。其中,可弯折部分的长度延伸方向是指与可弯折部分的弯折线平行的方向,比如可以为平行于电子设备20的显示面的平面内的任意方向。梯形结构的空隙可以使得可弯折部分在弯折过程中的应力可以比较分散在空隙的各个位置,避免集中在某一位置。需要说明的是,空隙222的截面形状并不限于梯形结构,比如空隙222的截面形状可以为矩形结构、或U形结构、或半圆形结构、或三角形结构、或不规则形状结构等。空隙222的内侧壁面并不限于平面结构,比如空隙222的内侧壁面可以为阶梯面结构、弧面结构、曲面结构或波浪面结构中的一种或几种的组合。The cross-sectional shape of the void 222 may be a trapezoidal structure, and the inner sidewall surface of the void 222 may be a planar structure. The cross-sectional shape of the void 222 in the embodiments of the present application refers to the cross-sectional shape obtained by cutting the void 222 perpendicular to the lengthwise extending direction of the bendable portion and perpendicular to the display surface direction of the electronic device 20 . The extension direction of the length of the bendable portion refers to a direction parallel to the bending line of the bendable portion, for example, it may be any direction in a plane parallel to the display surface of the electronic device 20 . The voids of the trapezoidal structure can make the stress of the bendable part during the bending process relatively dispersed in various positions of the voids, avoiding concentration in a certain position. It should be noted that the cross-sectional shape of the void 222 is not limited to a trapezoidal structure. For example, the cross-sectional shape of the void 222 may be a rectangular structure, a U-shaped structure, a semicircular structure, a triangular structure, or an irregular-shaped structure. The inner sidewall surface of the void 222 is not limited to a planar structure, for example, the inner sidewall surface of the void 222 may be one or a combination of a stepped surface structure, an arc surface structure, a curved surface structure or a wave surface structure.

在一些实施例中,玻璃层220包括用于形成空隙222的底壁和侧壁,底壁和侧壁之间圆滑过渡,比如可以将底壁和侧壁的相交位置设置为圆角,从而避免应力在底壁和侧壁相交的角落位置处集中,以减少由此对玻璃层220的疲劳强度带来的损耗,有利于提高玻璃层220的使用寿命。当空隙222的截面形状为梯形结构时,空隙222的开口宽度小于底壁的宽度。可以理解的是,梯形结构具有顶边和底边,其中顶边的长度小于底边的长度,其中空隙222的底壁作为梯形结构的顶边。In some embodiments, the glass layer 220 includes a bottom wall and a side wall for forming the void 222, and the transition between the bottom wall and the side wall is smooth. The stress is concentrated at the corner where the bottom wall and the side wall intersect, so as to reduce the loss caused by the fatigue strength of the glass layer 220 , which is beneficial to improve the service life of the glass layer 220 .
