Description

Technical Field

[0001] This invention relates to the field of display technology. More specifically, it relates to a display panel, a splicing display device, and a method for manufacturing the display panel. Background Technology

[0002] With the development of industries such as outdoor advertising and indoor education, large-screen displays have become an important branch of the display industry. However, due to the requirement for bonding the peripheral circuits and flexible circuits of the driver IC, there is a certain limit to the narrow bezel area of ​​the display screen. The bezel area of ​​the display screen cannot be displayed, which affects the forward display effect.

[0003] Furthermore, video wall is an important branch of large-size screens. Based on the above explanation, due to the existence of the bezel area, there will be a seam formed by the bezel area between two video wall screens. The seam directly affects the display effect, causing a visual sense of separation for the viewer and affecting the viewing experience. Summary of the Invention

[0016] The light-refracting structure is used to change the propagation direction of a portion of the light rays emitted from the second pixel area, so that the portion of the light rays exits at the position of the border area.

[0017] The direct-emitting light structure is used to transmit another portion of the light emitted from the second pixel area. Further, the polarizing substrate includes:

[0018] The fixing surface that is attached to the side of the second pixel region away from the substrate shown.

[0019] A light-emitting surface parallel to the surface of the display area away from the substrate, the orthogonal projection of the light-emitting surface onto the substrate covers the orthogonal projection of the border area onto the substrate;

[0020] A first sidewall, inclined and connecting the fixing surface and the light-emitting surface, forms a first angle with the surface of the frame area away from the substrate; and

[0021] The inclined second sidewall connecting the fixing surface and the light-emitting surface forms a second angle with the surface of the first pixel area near the substrate.

[0022] The first sidewall is parallel to the second sidewall, the first included angle and the second included angle are complementary, and the second included angle is greater than the first included angle.

[0023] Furthermore, each of the aforementioned direct-emission light structures includes:

[0044] Figure 4 This diagram illustrates the pixel structure of the display area after two display panels are spliced ​​together according to an embodiment of the present invention, viewed from above.

[0045] Figure 5 This diagram illustrates a side-view polarization structure after two display panels are spliced ​​together according to an embodiment of the present invention. Detailed Implementation

[0046] To more clearly illustrate the present invention, the following description, in conjunction with embodiments and accompanying drawings, further explains the invention. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of the present invention.

[0047] The first embodiment of the present invention proposes a display panel, such as Figure 1 and Figure 2 As shown, the display panel includes a display area 20 and a border area 30 adjacent to the display area 20. The display panel also includes a substrate 10 and a polarizing structure 40 disposed on the substrate 10 and located in the display area 20.

[0048] The display area 20 includes:

[0049] A first pixel region 21 and a second pixel region 22 surrounding the first pixel region 21, wherein the pixel density of the second pixel region 22 is greater than the pixel density of the first pixel region 21.

[0050] The polarizing structure 40 is used to change the propagation direction of some of the light emitted from the second pixel area 22, so that some of the light is emitted at the position of the border area 30, and the light emission direction of some of the light is parallel to the stacking direction of the display panel.

[0051] This invention, through a combination of pixel arrangement in the second pixel area 22 and a polarizing structure 40 on the side of the display area 20 away from the substrate 10, sets up a first pixel area 21 and a second pixel area 22 with different pixel densities. The density of the second pixel area 22 near the border area 30 is set to be greater than that of the first pixel area 21 away from the border area 30, thereby increasing the light emission of the second pixel area 22. The polarizing structure 40 polarizes part of the light emitted from the second pixel area 22 to the position of the border area 30, so that the light can be emitted from above the border area 30 (non-display area 20), realizing "pixel emission" in the non-display area.

[0052] In this embodiment, the display area and the bezel area of ​​the display panel are designed to be adjacent to each other, that is, the display panel of this embodiment can be as follows: Figure 1 The diagram shows a display area surrounded by a border area. In another embodiment, the display panel of this embodiment may also be as follows: Figure 4 The design shown includes splicing multiple display areas. In this structure, the border area is not only set on the edge of each display area, but also at the splicing position between two adjacent display areas. Therefore, the display panel of this embodiment can achieve "pixel light emission" in the border area adjacent to the display area.

[0053] In an optional embodiment, such as Figure 2 As shown, the polarizing structure 40 includes:

[0054] The polarizing substrate 41 includes a plurality of direct light-emitting structures 42 disposed on the polarizing substrate 41 and a plurality of refracted light-emitting structures 43 disposed on the polarizing substrate 41.

[0055] In a specific example, the polarizing substrate 41 is transparent glass, that is, it is equivalent to setting a polarizing substrate 41 on the film layer structure of the display area 20 as a carrier structure for the refracted light structure 43 and the direct light structure 42. The setting of transparent glass ensures the light output efficiency of the display panel.

[0056] In this embodiment, the light-refracting structure 43 is used to change the propagation direction of some of the light rays emitted from the second pixel area 22, so that some of the light rays are emitted at the position of the border area.

[0057] The direct light-emitting structure 42 is used to transmit another part of the light emitted from the second pixel area 22 without changing the light emission direction of the second pixel area 22. That is, the light emission direction of the other part of the light is also parallel to the stacking direction of the display panel.

[0058] With this setting, the second pixel area 22 can achieve positive light emission by using the direct light emission structure 42, and the second pixel area 22 can also achieve non-positive light emission by using the refracted light emission structure 43, that is, the light is reflected to the top of the border area 30 to achieve the display above the border area 30.

[0059] In a specific example, the light paths of the direct light-emitting structure 42 and the refracting light-emitting structure 43 are as follows: Figure 2 As shown,

[0060] For the direct light-emitting structure 42, each pixel at the corresponding position... Figure 2 The stacking direction shown is... Figure 2 The light emerges from the top of the cross-sectional view of the upper layer structure. The direct light-emitting structure 42 can directly transmit the light to the layer structure. That is, the direct light-emitting structure 42 does not change the light-emitting path of the pixel at the corresponding position, thereby achieving forward light emission.

[0061] For the refracted light structure 43, each pixel at the corresponding position first... Figure 2 The stacking direction shown is... Figure 2 Light emerges from the upper layer of the cross-sectional view, and then the light refracting structure 43 reflects the light emitted upwards for the first time, changing the position of the emitted light. Then, the light refracting structure 43 reflects the light reflected for the second time. The emission direction of the light whose position has changed is designed so that the light after the second reflection is emitted from the position of the light-emitting surface in a direction perpendicular to the light-emitting surface, thereby realizing the visible display light at the position of the frame area 30.

[0062] In an optional embodiment, the polarizing substrate 41 includes:

[0063] The fixing surface 411 of the second pixel area 22 away from the substrate 10 is, in a specific example, fixed to the uppermost film layer in the stacking direction of the display panel, for example, by adhesive bonding.

[0064] A light-emitting surface 412 parallel to the surface of the substrate 10 near the polarizing substrate 41 has its orthogonal projection on the substrate 10 covering the orthogonal projection of the frame area 30 on the substrate 10. This arrangement enables the light emitted by the light-emitting surface 412 to cover the frame area 30, thereby achieving light emission from the entire frame area 30 and improving the display effect of the frame area 30.

[0065] The inclined first sidewall 413 connecting the fixing surface 411 and the light-emitting surface 412 forms a first included angle α with the surface of the frame area 30 away from the substrate 10; and

[0066] The inclined second sidewall 414 connecting the fixing surface 411 and the light-emitting surface 412 forms a second included angle β with the surface of the first pixel area 21 near the substrate 10.

[0067] The first included angle α and the second included angle β are complementary, and the second included angle β is greater than the first included angle α.

[0068] In this embodiment, the first sidewall 413 and the second sidewall 414 serve as supporting surfaces for the refracting light structure 43 and the direct light structure 42. Figure 2 As shown, the first included angle α and the second included angle β are complementary, and the second included angle β is greater than the first included angle α. That is, the carrier substrate of this embodiment has an inclined structure, thereby realizing the design of changing the light emission position. Based on the complementary arrangement of the first included angle α and the second included angle β, the first sidewall 413 is parallel to the second sidewall 414, ensuring that the reflection angle of the light through the first sidewall 413 and the reflection angle through the second sidewall 414 are the same, so that the light can be emitted towards the surface perpendicular to the display area 20. Therefore, through the above-mentioned common design, this embodiment of the invention achieves the purpose of changing the light emission position of the second pixel area 22 and ensuring that the final light emission direction is positive.

[0069] In an optional embodiment, the first included angle α is 45 degrees. With this setting, when the display panels are spliced, the light emission effects of the border areas 30 of the two display panels will not overlap, thus avoiding the light entering the human eye from overlapping at the spliced ​​border area 30 and ensuring the display effect.

[0070] Furthermore, such as Figure 2 As shown, the polarizing substrate 41 is symmetrically arranged with respect to the central axis of the second pixel area 22, so that the display can be realized on the surrounding border area 30.

[0071] like Figure 1 As shown, the second pixel area 22 is a ring-shaped design surrounding the first pixel area 21. At this time, the border area 30 is also a ring-shaped arrangement surrounding the second pixel area 22. Figure 2 As can be seen from the embodiment shown, a polarizing structure 40 is provided on one side of each second pixel area 22 of the ring structure. That is, the polarizing structure 40 is also a ring design, thereby polarizing part of the light from the second pixel area 22, thereby changing the light emission position and ensuring that the light emission direction is positive, so that the display light of the border area 30 can enter the human eye.

[0072] Figure 2 It shows Figure 1 The horizontal layer structure design of the display panel in the middle, in the cross-sectional direction, Figure 2 Only the schematic diagram of the left and right border areas 30 of the second pixel area 22 is shown. Correspondingly, the polarizing structures 40 are respectively set on both sides of the second pixel area 22, arranged symmetrically. It can be understood that... Figure 1 The vertical polarization structure 40 of the display panel shown is also symmetrically designed in the second pixel area 22, realizing polarized display around the border area 30.

[0073] like Figure 1 and Figure 2 As shown, the polarizing structure 40 of this embodiment is a combination design of the pixel arrangement of the second pixel area 22. In an optional embodiment, the first pixel area 21 includes a plurality of arrayed first pixel units 211, and the first pixel unit 211 includes a first red pixel 211R, a first blue pixel 211B, and a first green pixel 211G.

[0074] The second pixel area 22 includes a plurality of second pixel units 221 arranged in an array. The second pixel unit 221 includes two second red pixels 221R, two second blue pixels 221B, and two second green pixels 221G.

[0075] In other words, this embodiment does not change the overall area of ​​the display area 20, ensuring normal display of the display area 20. However, this embodiment designs the number of pixels in the first pixel unit 211 and the second pixel unit 221, setting the number of the first pixel unit 211 to an integer multiple of the number of the second pixel unit 221, for example, as... Figure 1 As shown, the first pixel unit 211 has three pixels, and the second pixel unit 221 has six pixels. For pixels of the same color, the number of pixels in the second pixel unit 221 is twice the number of pixels in the first pixel unit 211. That is, the density of the second pixel unit 221 is increased, but the light-emitting area of ​​each pixel is reduced relative to the light-emitting area of ​​the corresponding pixel in the first pixel unit, thus ensuring display uniformity.

[0076] Furthermore, in an optional embodiment, the light-emitting area of ​​the first red pixel 211R is a preset multiple of the light-emitting area of ​​the two second red pixels 221R;

[0077] The light-emitting area of ​​the first blue pixel 211B is a preset multiple of the light-emitting area of ​​the two second blue pixels 221B;

[0078] The luminous area of ​​the first green pixel 211G is a preset multiple of the luminous area of ​​the two second green pixels 221G.

[0079] In a specific example, such as Figure 2 As shown, the total luminous area of ​​a certain color pixel in the first pixel area 21 is twice that of the corresponding color pixels in the second pixel area 22.

[0080] That is, Figure 2 As shown, the total luminous area of ​​the two second blue pixels 221B is half the luminous area of ​​the second blue pixel 221B. That is, the luminous area of ​​one second blue pixel 221B is one-quarter of the luminous area of ​​the second blue pixel 221B. This setting does not increase the process, and it can be formed by setting a mask, which can ensure process efficiency.

[0081] Figure 1 As shown, the second pixel area has a ring-shaped design, including a horizontal second pixel area and a vertical second pixel area. In this embodiment, the pixel arrangement of the horizontal and vertical second pixel areas is further designed. In an optional embodiment,

[0082] In the vertical second pixel area, the first blue pixel is cut with a horizontal tangent and then with a vertical tangent to obtain two independent second blue pixels in the second pixel unit. The first green pixel is cut with a horizontal tangent and then with a vertical tangent to obtain two independent second red pixels in the second pixel unit. The first red pixel is cut with a horizontal tangent and then with a vertical tangent to obtain two independent second green pixels in the second pixel unit.

[0083] In the horizontal second pixel area, the second blue pixel is cut with a horizontal tangent, and then cut with another horizontal tangent to obtain two independent second blue pixels in the second pixel unit. The first green pixel is cut with a horizontal tangent, and then cut with another horizontal tangent to obtain two independent second red pixels in the second pixel unit. The first red pixel is cut with a horizontal tangent, and then cut with another horizontal tangent to obtain two independent second green pixels in the second pixel unit.

[0084] In other words, after the area of ​​the second pixel unit is reduced by the area of ​​the first pixel unit, each pixel in the vertical second pixel area is divided into two by the vertical tangent, and each pixel in the horizontal second pixel area is divided into two by the horizontal tangent. Through this setting, the polarizing structure can effectively reflect the light emitted by the horizontal and vertical pixels.

[0085] In an optional embodiment, the light-emitting area of ​​the first blue pixel is smaller than that of the first green pixel and smaller than that of the first red pixel. The pixel size of the first blue pixel is greater than 200*300 micrometers. Considering that the light-emitting area of ​​the second pixel area 22 near the border area 30 is reduced in this embodiment, in order to ensure the process accuracy of the second pixel area 22 with a small light-emitting area, the pixels of the first pixel area 21 are designed to a certain size. The light-emitting area of ​​the first pixel area 21 is a preset multiple of the corresponding second color pixel of the second pixel area 22, ensuring that the process of the second pixel area 22 can proceed normally.

[0086] Based on the above embodiments, the pixel area of ​​the second pixel area 22 is relatively large. That is, this embodiment is based on the design of large-size pixels and large-size display screens, thereby enabling the design of two pixel areas of different sizes, such as information screens on highways, promotional televisions, and other large screens.

[0087] In an optional embodiment, such as Figure 2 and Figure 3 As shown, Figure 3 The diagram shows the structure of two columns of border areas 30 in the top view direction, and a polarizing structure 40 for polarizing the column border areas 30 in the layer structure direction.

[0088] like Figure 3 As shown in the upper structure, each of the direct-emission light structures 42 includes:

[0089] A first direct-light prism 421 corresponding to the position of the second red pixel 221R is disposed on the second sidewall 414, a second direct-light prism 422 corresponding to the position of the second green pixel 221G is disposed on the second sidewall 414, and a third direct-light prism 423 corresponding to the position of the second blue sub-pixel is disposed on the second sidewall 414.

[0090] In an optional embodiment, the first direct-light prism 421, the second direct-light prism 422, and the third direct-light prism 423 have a magnification function, which can compensate for the light emitted directly and improve the forward display effect. In a specific example, the magnification function can be achieved by setting a convex lens with a preset fixed magnification factor on the light channel of the first direct-light prism 421, the second direct-light prism 422, and the third direct-light prism 423. The preset fixed magnification factor of the convex lens for the pixel can be matched with the preset magnification factor of the first pixel area 21 and the second pixel area 22, so as to reduce the parallax caused by the difference in pixel size between the first pixel area 21 and the second pixel area 22.

[0091] Each of the aforementioned light-refracting structures 43 includes:

[0092] The second sidewall 414 comprises a first refractive prism 431 located at the position of the second red pixel 221R, a second refractive prism 432 located at the position of the second green pixel 221G, a third refractive prism 433 located at the position of the second blue sub-pixel, and a fourth refractive prism 434 covering the entire surface of the first sidewall 413 near the second sidewall 414.

[0093] The first direct-view prism 421 and the first refracting prism 431 are located at different positions of the second red pixel 221R.

[0094] The second direct prism 422 and the second refracting prism 432 are located at different positions of the second green pixel 221G.

[0095] The third direct prism 423 and the third refractive prism 433 are located at different positions of the second blue pixel 221B.

[0096] This embodiment achieves both direct light emission from the second pixel region 22 of the aforementioned direct light emission structure 42 and non-direct light emission from the second pixel region 22 of the aforementioned reflective light emission structure through a combination design of a direct light emission prism and a reflective light emission prism.

[0097] In a specific example, each direct-emitting light structure 42 includes a first direct-emitting prism 421, a second direct-emitting prism 422, and a third direct-emitting prism 423. Since the second color pixels of the second pixel area 22 are arranged in an array, there can also be multiple direct-emitting light structures 42 arranged in an array, so that the entire area of ​​the second pixel area 22 in the column direction can achieve forward light emission.

[0098] Similarly, each of the aforementioned light-refraction structures 43 includes a first refraction prism 431, a second refraction prism 432, and a third refraction prism 433. Since the first color pixels of the first pixel area 21 are arranged in an array, there can also be multiple light-refraction structures 43 arranged in an array, and the entire area of ​​the first refraction pixel area in the column direction can achieve forward light emission.

[0099] In this embodiment, the first direct prism 421 and the first refractive prism 431 are located at different positions of the second red pixel 221R, the second direct prism 422 and the second refractive prism 432 are located at different positions of the second green pixel 221G, and the third direct prism 423 and the third refractive prism 433 are located at different positions of the second blue pixel 221B.

[0100] To avoid conflicts between the positions of refractive and direct prisms, only one type of prism is set at the position corresponding to each color pixel, so that only one function of refraction or direct projection can be achieved.

[0101] In a specific example, the structure for light propagation is as follows: Figure 2 and Figure 3 As shown, specifically,

[0102] In the top-view orientation, taking prisms of the same type set in the same column as an example, prisms located at different second-color pixel positions in the same column will appear as the same position on the cross-sectional view.

[0103] Specifically, taking the second pixel area 22 near the left border area 30 and the polarizing structure 40 on the second pixel area 22 as an example, the first column is the second refractive prism 432 and the third refractive prism 433, the third column is the first refractive prism 431; the second column is the second direct prism 422 and the third direct prism 423, and the fourth column is the first direct prism 421.

[0104] The second direct-light prism 422 and the third direct-light prism 423 in the second column transmit green and blue light directly, respectively, while the first direct-light prism 421 in the fourth column transmits red light directly, ensuring that the second pixel area 22 can emit light in the positive direction.

[0105] The first column consists of the second refracting prism 432 and the third refracting prism 433, which reflect green and blue light for the first time, respectively. The first refracting prism 431 in the fourth column reflects red light for the first time, thereby changing the light output position. The red, green, and blue light after the first reflection are reflected a second time by the fourth refracting prism, so that the red, green, and blue light reflected a second time are emitted through the light output surface 412, so that the light can be emitted from the position above the frame area 30.

[0106] In an optional embodiment, the second blue pixel 221B, the second red pixel 221R, and the second green pixel 221G corresponding to the light-refracting structure 43 may be located in the same or different second pixel units 221.

[0107] That is, the embodiments of the present invention do not limit whether the light-reflecting structure 43 must be set in the same pixel unit. As long as one light-reflecting structure 43 can correspond to each second blue pixel 221B, second red pixel 221R, and second green pixel 221G respectively, light emission can be achieved based on the principle of light synthesis.

[0108] Similarly, the first blue pixel 211B, the first red pixel 211R, and the first green pixel 211G corresponding to the direct light emission structure 42 can be located in the same or different second pixel units 221. As long as one direct light emission structure 42 can correspond to each of the second blue pixel 221B, the second red pixel 221R, and the second green pixel 221G respectively, light emission can be achieved based on the principle of light synthesis.

[0109] Considering that the second blue pixel 221B, the second red pixel 221R, and the second green pixel 221G in a pixel unit are relatively close to each other, making it easier to generate light, in a preferred embodiment, a second pixel unit 221 corresponds to a refracted light-emitting structure 43 or a direct light-emitting structure 42.

[0110] In an optional embodiment, the surface of the first sidewall 413 on the side away from the second sidewall 414 has a roughened structure.

[0111] like Figure 2 As shown, the surface of the first sidewall 413 near the second sidewall 414 is configured as a fourth refractive prism, thereby reflecting the light generated by the first refractive prism 431, the second refractive prism 432 and the third refractive prism 433 in a second time to ensure the consistency of the light output direction. In order to improve the reflection efficiency after the first refractive prism 431, the second refractive prism 432 and the third refractive prism 433 are incident, the embodiment of the present invention designs the surface of the first sidewall 413 away from the second sidewall 414, and sets a roughened structure on the surface, such as frosting or designing an uneven structure, to reduce the light transmittance and ensure the light efficiency.

[0112] In another optional embodiment, the direct light-emitting structure and the refracted polarizing structure of the present invention can be fiber optic structures. The input end of the fiber optic in each light-emitting structure corresponds to a second color pixel, that is, the second red pixel, the second blue pixel, and the second green pixel correspond to different fiber optic structures. The output end of each fiber optic structure is located in the non-display area. The light transmission characteristics of the fiber optic are used to realize "pixel light emission" in the frame area. This solution is more expensive than the aforementioned prism embodiment. Those skilled in the art can choose the corresponding polarization scheme according to the actual application, which will not be elaborated here.

[0113] In an optional embodiment, the boundary of the second pixel area 22 is an arc-shaped structure, and the fixed surface 411 is an arc-shaped structure that matches the boundary of the second pixel area 22.

[0114] In this embodiment, considering that the edge of the display panel is an irregular design, such as a curved screen with an arc-shaped boundary, in order to ensure that the display panel and the polarizing structure 40 can be fixed, in this embodiment, the fixing surface 411 is set as an arc-shaped structure that cooperates with the second pixel area 22 near the border area 30 to achieve the display characteristics.

[0115] In an optional embodiment, the width of the orthographic projection of the second pixel area 22 onto the substrate 10 is equal to the width of the orthographic projection of the border area 30 onto the substrate 10. With this setting, the light-emitting area of ​​the second pixel area 22 can cover the border area 30, thereby realizing light emission at the position of the border area 30.

[0116] Based on the display panel of the above embodiments of the present invention, by designing the pixels of the second pixel area 22 near the border area 30 and combining the light polarization design of the polarization structure 40 of the second pixel area 22, the purpose of changing the light emission position of the second pixel area 22 and ensuring that the final light emission direction is positive light emission can be achieved, so that the pixels of the second pixel area 22 at the edge emit light from the border area 30, which greatly improves the visual effect at the edge position.

[0117] Another embodiment of the present invention provides a method for manufacturing the display panel described in another embodiment of the present invention, the method comprising:

[0118] The display area 20 is formed on the substrate 10. The display area 20 includes a first pixel area 21 and a second pixel area 22 surrounding the first pixel area 21, wherein the pixel density of the second pixel area 22 is greater than the pixel density of the first pixel area 21.

[0119] A border area 30 adjacent to the display area 20 is formed on the substrate 10;

[0120] A polarizing structure 40 is formed on the substrate 10 at a position corresponding to the display area 20, away from the substrate 10. The polarizing structure 40 is used to change the propagation direction of a portion of the light emitted from the second pixel area 22, so that the portion of the light is emitted at the position of the border area 30, and the light emission direction of the portion of the light is parallel to the stacking direction of the display panel.

[0121] The method described in this embodiment of the invention does not add complex process steps. The design of the first pixel area 21 and the second pixel area 22 can be formed by the same process, ensuring process manufacturing efficiency. The design of the polarizing structure 40 is not complicated in the process manufacturing. Therefore, the manufacturing method of this embodiment of the invention is simple and has high process efficiency.

[0122] Another embodiment of the present invention provides a display device, such as Figure 4As shown, the display device includes a plurality of adjacent display panels as described in the above embodiments of the present invention, such as large-sized display devices like video wall displays.

[0123] like Figure 4 As shown, the structural design of two display panels being spliced ​​together is illustrated. In the top view, after splicing two adjacent display panels in this embodiment of the invention, the thickness of the border area 30 increases. Compared with related technologies, light cannot be emitted from the border area 30, thus creating a visual break in the display. However, the display panel in this embodiment of the invention can change the display position and polarize part of the light from the second pixel area 22 to the border area 30, thereby enabling visual illumination of the border area 30 and improving the visual break in the splicing device.

[0124] like Figure 5 As shown, embodiments of the present invention are illustrated. Figure 3 The splicing structure at the indicated location corresponds to the top-view structural design and the splicing design of the polarizing structure 40. Figure 5 As can be seen from the image, the polarizing structure 40 is symmetrical with the splicing line at the splicing position, which realizes the visual light emission of the adjacent frame area 30 of the two display panels.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here.
