Detailed implementation manners

[0041] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0042] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be of the ordinary meaning understood by those of ordinary skill in the field to which the present application belongs.

[0043] With the rapid development of display technology, various novel display panels have emerged. Referring to Figure 1-2 as shown, there is a related display panel 100. The display panel 100 includes a first screen body 10 and a second screen body 20. The second screen body 20 is connected to the first screen body 10 through a connection area 80, and the connection area 80 is located between the second screen body 20 and the first screen body 10. Further, the first screen body 10 is foldable, wherein, Figure 1 is a schematic diagram of the first screen body 10 in a semi-expanded state, Figure 2FIG. 0 is a schematic diagram of the first screen body 10 in a fully unfolded state. In the fully unfolded state, the first display area 16 and the second display area 17 on the first screen body 10 form a large display area for display; in the folded state, the first display area 16 and the second display area 17 are hidden inside the display panel 100 and can be displayed through the second screen body 20.

[0044] Please continue to refer to Figure 2 As shown, the data line 21 of the first screen body 10 is connected to the second screen body 20 through the FIAA (Fanout in AA, fan-out routing is set in the display area) technology. The display panel 100 further includes a control module 50, which is usually disposed at the lower border of the first screen body 10. One end of the data line 21 close to the control module 5 is electrically connected to the control module 50. Since the data line 21 in the second screen body 20 has the same routing as the data line in the first screen body 10, the second screen body 20 and the first screen body 10 share the data line 21.

[0045] It should be noted that Figure 2 in FIG., the second screen body 20 is located above the first screen body 10, and the control module 50 is located below the first screen body 10, just for the convenience of showing the routing. In the actual product, the second screen body 20 is always located on the side of the display device opposite to the first screen body 10, and the second screen body 20 cannot be unfolded or folded. Refer to Figure 1 wherein, in order to reduce the size of the lower border of the display panel 100, the control module 50 is usually bonded to the side of the display panel 100 opposite to the first screen body 10.

[0046] After long-term research by the inventor, it is found that since an avoidance area 60 needs to be reserved on one side of the second screen body 20 to avoid cameras and the like. Therefore, the size of the second screen body 20 in the second direction (such as the X direction in the figure) is smaller than the size of the second screen body 20 in the second direction, resulting in part of the data line 21 in the first screen body 10 extending into the second screen body 20 and sharing it with the second screen body 20, and the other part of the data line 21 is used alone by the first screen body 10. The lengths of these two parts of the data line 21 are different, which causes a large difference in data delay in the areas where these two parts of the data line 21 are located in the first screen body 10, thereby resulting in uneven display on the first screen body 10.

[0047] Based on this, the present application provides a display panel solution to solve the above technical problems. For details, please refer to the following embodiments.

[0048] Refer to Figure 3 As shown, an embodiment of the present application discloses a display panel 100, including a first screen body 10 and a second screen body 20 connected to each other, as well as a plurality of first data lines 30, a plurality of second data lines 40, and a control module 50.

[0049] The first data line 30 is electrically connected to the first screen body 10. The first data line 30 extends along a first direction (the Y direction in the figure) and is located on the first screen body 10. The second data line 40 is electrically connected to the second screen body 20. The second data line 40 extends along the first direction. The second data line 40 is located between the first screen body 10 and the second screen body 20. The control module 50 is electrically connected to the first data line 30 to drive the first screen body 10, and is also electrically connected to the second data line 40 to drive the second screen body 20.

[0050] Among them, the first data line 30 and the second data line 40 extend in the same direction. The first data line 30 is used to drive the first screen body 10, and the second data line 40 is used to drive the second screen body 20. The first screen body 10 and the second screen body 20 do not share a common data line. The control module 50 drives the first data line 30 and the second data line 40 separately. Among them, the first data line 30 and the second data line 40 can share the same control module 50, or two control modules 50 can be used to drive the first data line 30 and the second data line 40 respectively.

[0051] The display panel 100 provided in this embodiment drives the first screen body 10 through the first data line 30 and drives the second screen body 20 through the second data line 40, realizing separate driving between the first screen body 10 and the second screen body 20, avoiding the situation that the first screen body 10 and the second screen body 20 share a data line, which may cause a large difference in data delay in different regions of the first screen body 10, resulting in uneven display of the first screen body 10. This is beneficial to improving the uniformity of display and enhancing the display effect of the display panel 100.

[0052] Specifically, the first data line 30 is used to drive the pixel circuits in the first screen body 10, and the second data line 40 is used to drive the pixel circuits in the second screen body 20.

[0053] It should be noted that Figure 3 in the figure, the second screen body 20 is located above the first screen body 10, and the control module 50 is located below the first screen body 10, just for the convenience of showing the wiring. In an actual product, the second screen body 20 is always located on the side of the display device opposite to the first screen body 10, and the second screen body 20 cannot be unfolded or folded. Refer to Figure 1 Among them, in order to reduce the size of the lower border of the display panel 100, the control module 50 is usually bonded to the side of the display panel opposite to the first screen body 10.

[0054] Please continue to refer to Figure 3As shown, in one embodiment, the second data line 40 includes a first segment 41 located within the first screen body 10 and a second segment 42 located within the second screen body 20. Among them, the second data line 40 extends through the first screen body 10 to the second screen body 20, that is, a part of the second data line 40 is located within the first screen body 10 and a part is located within the second screen body 20, so as to transmit data signals to the second screen body 20 and drive the pixel circuits within the second screen body 20.

[0055] In one embodiment, the first screen body 10 includes a first display area 11 and a second display area 12 arranged along the second direction (such as the X direction in the figure); the first data line 30 includes a first partial data line 31 and a second partial data line 32 arranged along the second direction. The first partial data line 31 is located within the first display area 11, and the second partial data line 32 is located within the second display area 12. The first data line 30 is arranged at equal intervals along the second direction within the first screen body 10; among them, the second direction intersects with the first direction.

[0056] Among them, the first data line 30 is arranged at equal intervals along the second direction within the first screen body 10, which is beneficial to further improving the uniformity of the graphics and ensuring the uniformity of the display.

[0057] Please refer to Figure 4 As shown, in one embodiment, the display panel 100 further includes an avoidance area 60. The avoidance area 60 and the second screen body 20 are arranged along the second direction. The first screen body 10 includes a first display area 11 and a second display area 12 arranged along the second direction. The orthographic projection of the second screen body 20 on the first screen body 10 is located within the first display area 11, and the orthographic projection of the avoidance area 60 on the first screen body 10 is located within the second display area 12. In this embodiment, the second screen body 20 and the first display area 11 are respectively located on the opposite sides of the display panel 100. And the second screen body 20 is used as a secondary screen, which is usually smaller and is used to achieve quick display and operation. Locating the orthographic projection of the second screen body 20 on the first screen body 10 within the first display area 11 and the orthographic projection of the avoidance area 60 on the first screen body 10 within the second display area 12 is beneficial to ensuring a high screen-to-body ratio.

[0058] Specifically, the first display area 11 and the second display area 12 are bounded by a dotted line extending in the first direction in the figure. Due to the existence of the avoidance area 60, the size of the second screen body 20 in the second direction is smaller than the size of the second screen body 20 in the second direction. At this time, if the second screen body 20 and the first screen body 10 share data lines, the shared data lines will go through the first display area 11, and the data lines in the second display area 12 will not extend to the second screen body 20, which will cause the length of the data lines in the first display area 11 to be greater than the length of the data lines in the second display area 12, which will cause a large difference in data delay between the first display area 11 and the second display area 12, thereby causing uneven display of the first screen body 10. In this embodiment, the first display area 11 and the second screen body 20 no longer share data lines, avoiding differences in data delay between the first display area 11 and the second display area 12, and improving the uniformity of the display of the first screen body 10.

[0059] Preferably, the second direction is perpendicular to the first direction. In other embodiments, the first direction may be 70 degrees, 80 degrees, etc., to the second direction, which is not specifically limited.

[0060] Reference Figure 5 As shown, in one embodiment, the avoidance area 60 is used to form a hole area 61, and the hole area 61 is used to accommodate a camera or the like.

[0061] Reference Figure 6 As shown, in one embodiment, the display panel 100 further includes a plurality of virtual wirings 70, which are located in the second display area 12 and extend along the first direction. The virtual wirings are used to ensure the uniformity of the pattern, thereby improving the display effect.

[0062] In one embodiment, along the second direction, adjacent virtual wirings 70 are arranged at equal intervals, and adjacent second data lines 40 are arranged at equal intervals, which is beneficial to further improve the uniformity of the pattern and ensure the uniformity of the display.

[0063] Preferably, the distance between the virtual routing line 70 closest to the first display area 11 and the second data line 40 closest to the second display area 12 is equal to the distance between adjacent second data lines 40. Specifically, the distance between adjacent virtual routing lines 70 is equal to the distance between adjacent second data lines 40, which is equal to the distance between the virtual routing line 70 closest to the first display area 11 and the second data line 40 closest to the second display area 12, so that along the second direction, the virtual routing line 70 and the first segment 41 are evenly arranged, further improving the uniformity of the pattern and ensuring the uniformity of the display.

[0064] In one embodiment, the virtual trace 70 is connected to the power signal line, and the power signal line can provide a stable fixed potential, which helps to improve the performance and stability of the circuit. Specifically, the virtual trace 70 is connected to the positive power signal line ELVDD or the negative power signal line ELVSS.

[0065] In one embodiment, the display panel 100 further includes a connection area 80. The second screen body 20 is connected to the first screen body 10 through the connection area 80, and the connection area 80 extends along the second direction. Wherein, the connection area 80 is a non-display area, and a part of the second data line 40 is located in the connection area 80, and the connection area 80 is located on the side of the display device.

[0066] In one embodiment, a gap is formed between adjacent first data lines 30, and the first segment 41 is located in the gap. Specifically, the first segment 41 can be fabricated on the same layer as the first data line 30. In order to avoid interference with the first data line 30, the first segment 41 is arranged in the gap between adjacent first data lines 30. In another embodiment, the first segment 41 can be on a different layer from the first data line 30.

[0067] Referring to Figure 7 As shown, in one embodiment, the first screen body 10 includes a first folding area 13, a bending area 14, and a second folding area 15 arranged along the first direction. The bending area 14 connects the first folding area 13 and the second folding area 15. The first folding area 13 and the second folding area 15 can expand or fold the first screen body 10 through the bending area 14, and the control module 50 is located at one end of the second folding area 15. Referring to Figure 8 As shown, in the unfolded state, the first folding area 13 and the second folding area 15 are combined into a large display area for display, improving the display effect and user experience; referring to Figure 9 As shown, in the folded state, the first screen body 10 is hidden inside the display panel 100, and the display can be performed through the display area on the second screen body 20, which is more compact and convenient to carry. It should be noted that the bending area 14 is also a display area.

[0068] Wherein, the first folding area 13, the bending area 14, and the second folding area 15 are bounded by the dotted line extending along the second direction in the figure. The first display area 11, the second display area 12, the first folding area 13, the bending area 14, and the second folding area 15 are only regions obtained by dividing the first screen body 10 in different directions. Specifically, the first display area 11 and the second display area 12 are divided along the second direction, and the first folding area 13, the bending area 14, and the second folding area 15 are divided along the first direction. The display area composed of the first display area 11 and the second display area 12 is the same as the display area composed of the first folding area 13, the bending area 14, and the second folding area 15.

[0069] Please continue to refer to Figure 9As shown, in one embodiment, when the first screen body 10 is in the folded state, a part of the first folding area 13 is located between the second folding area 15 and the second screen body 20, ensuring that the display panel 100 is more compact and convenient to carry.

[0070] In one embodiment, when the first screen body 10 is in the unfolded state, the orthographic projection of the second screen body 20 on the first screen body 10 is located outside the second folding area 15. This ensures that the second screen body 20 can be normally displayed regardless of whether the first screen body 10 is folded or unfolded. Among them, when the first screen body 10 is in the unfolded state, the second screen body 20 and the control module 50 are on the same side of the display panel 100.

[0071] In one embodiment, when the first screen body 10 is in the folded state, the orthographic projection of the first folding area 13 on the second folding area 15 coincides with the second folding area 15, that is, the first folding area 13 is symmetrically arranged along the bending area 14 on the second folding area 15, ensuring that the size of the first screen body 10 after folding is smaller.

[0072] Another embodiment of the present application discloses a display device, which includes the display panel 100 in the above embodiment. This display device can be used in smart devices (such as mobile phones, VR devices, computers, televisions, in-vehicle displays, etc.).

[0073] For the display device provided in this embodiment, its display panel 100 drives the first screen body 10 through the first data line 30 and drives the second screen body 20 through the second data line 40, realizing separate driving between the first screen body 10 and the second screen body 20, avoiding the sharing of data lines between the first screen body 10 and the second screen body 20, resulting in large differences in data delay in different areas of the first screen body 10, thereby causing uneven display of the first screen body 10, which is beneficial to improving the uniformity of display, enhancing the display effect of the display panel 100, and enhancing the performance of the display device.
