[0002] Display technology has always been one of the important research directions in electronic devices. For display panels with backlight sources such as liquid crystal displays, display brightness is one of the important specifications of liquid crystal displays.

[0003] For the 8-domain pixel structure design of traditional LCDs, during the manufacturing process, the shared electrode of the pixel and the metal layer where it is located are etched at the same time, resulting in uneven etching of the edge of the shared electrode, which is easy to form jagged edges, resulting in jagged edges and dark fields in the final display effect. In addition, since it is necessary to consider the alignment accuracy of the metal layer where the shared electrode is located, the pad layer is added, and the width of the metal layer where the shared electrode is located is increased. Therefore, the light-transmitting area of ​​the LCD screen is inevitably reduced, and the transmittance of the light emitted by the backlight source is also reduced. At the same time, the 8-domain pixel structure design of the traditional LCD uses 3 thin-film transistor driving technology.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] This application provides a display panel 1, please refer to Figure 1 and Figure 2 , Figure 1 A schematic top view of a display panel provided in one embodiment of the present application; Figure 2 for Figure 1The display panel 1 includes an array substrate 11, the array substrate 11 includes a plurality of gate lines 111 extending along a first direction D1, a plurality of data lines 112 extending along a second direction D2, and a plurality of pixel units 113 defined by the intersection of the gate lines 111 and the data lines 112; the pixel unit 113 includes a first pixel electrode 1131, a second pixel electrode 1132, a first driving circuit 1133, and a second driving circuit 1134, the first pixel electrode 1131 and the second pixel electrode 1132 are arranged at intervals in the second direction D2, the first pixel electrode 1131 includes a first body 113a and a second body 113a extending from the first body 113a to the second pixel electrode 1134. The second pixel electrode 1132 includes a first extension portion 113b extending from the second pixel electrode 1132, and the second pixel electrode 1132 includes a second body 113c and a second extension portion 113d extending from the second body 113c to the first pixel electrode 1131, the first driving circuit 1133 and the second driving circuit 1134 are arranged in the gap between the first pixel electrode 1131 and the second pixel electrode 1132, and are spaced apart from the first extension portion 113b and the second extension portion 113d, the first pixel electrode 1131 is electrically connected to the first driving circuit 1133, and the second pixel electrode 1132 is electrically connected to the second driving circuit 1134.

[0038] It should be noted that the light emitted by the light source can pass through the area where the first pixel electrode 1131 and the second pixel electrode 1132 are located, but cannot pass through or can only rarely pass through the area where the first driving circuit 1133 and the second driving circuit 1134 are located. Since display brightness is one of the specifications for testing the display, in order to achieve a better display effect, the area proportion of the first pixel electrode 1131 and the second pixel electrode 1132 should be as large as possible. In the related art, the pixel unit 113 also includes a shared electrode, and the shared electrode and the metal layer are etched in the same process, which easily leads to uneven etching of the edge of the shared electrode, thereby forming a jagged edge at the edge, and the phenomenon of the jagged edge light dark field occurs. Therefore, in the related art, a pad layer is usually added to the metal layer, and the line width of the pad layer is greater than the width of the shared electrode to achieve the shielding of the shared electrode. However, this setting method reduces the proportion of the pixel electrode area, thereby reducing the light passing through the pixel electrode and reducing the light transmittance. Meanwhile, in the related art, three driving circuits are used to drive the first pixel electrode 1131 and the second pixel electrode 1132 to work respectively, which also reduces the proportion of the pixel electrode area and reduces the light transmittance.

[0039] Understandably, Figure 2 Each of the same fill patterns in the diagram represents the same hierarchical structure, and part of the hierarchical structure is shown in perspective. Figure 2 , please refer to the cross-sectional schematic diagram provided below in this application for the specific hierarchical relationship. In this embodiment, the array substrate 11 is applied to a liquid crystal display, that is, a light source is also provided in the display panel 1, and the light emitted by the light source passes through at least part of the array substrate 11 and is emitted from one side surface of the display panel 1, and the array substrate 11 plays a role in dimming the light emitted by the light source. Specifically, the display panel 1 also includes liquid crystal, and its working principle is to apply a certain voltage to the upper and lower sides of the liquid crystal, thereby changing the rotation angle of the liquid crystal and adjusting the transmittance of the light passing through the liquid crystal, thereby realizing the display function of the picture of the display panel 1.

[0040] Specifically, Figure 2 As shown, the first driving circuit 1133 drives the first pixel electrode 1131 to work, and the second driving circuit 1134 drives the second pixel electrode 1132 to work. By reducing the number of shared electrodes and driving circuits, the gap remaining space between the adjacent first pixel electrodes 1131 and the second pixel electrodes 1132 becomes larger, so that the first pixel electrode 1131 can extend at least partially to the second pixel electrode 1132, and the second pixel electrode 1132 can extend at least partially to the first pixel electrode 1131, that is, the first extension portion 113b and the second extension portion 113d, so that the area proportion of the first pixel electrode 1131 and the second pixel electrode 1132 is increased, and the amount of light passing through the first pixel electrode 1131 and the second pixel electrode 1132 is increased, thereby improving the light transmittance; at the same time, since the shared electrodes are reduced, the edge etching of the shared electrodes will not be uneven, the phenomenon of the dark field of the jagged edge light is improved, and the display quality of the display panel 1 is improved.

[0041] It can be understood that in this embodiment, by reducing the number of shared electrodes and driving circuits, the first extension portion 113b and the second extension portion 113d can be arranged in the gap between the adjacent first pixel electrode 1131 and the second pixel electrode 1132, thereby increasing the area of ​​the first pixel electrode 1131 and the second pixel electrode 1132, that is, increasing the light-transmitting area of ​​the display panel 1, thereby improving the transmittance of the light emitted by the light source and improving the display effect of the display panel 1.

[0042] In one possible implementation, please refer again to Figure 2 The first driving circuit 1133 and the second driving circuit 1134 are disposed adjacent to the data line 112 , and the first extending portion 113 b and the second extending portion 113 d are disposed away from the same data line 112 .

[0043] Specifically, the first driving circuit 1133 and the second driving circuit 1134 are arranged in the gap between the adjacent first pixel electrode 1131 and the second pixel electrode 1132, and the first driving circuit 1133 and the second driving circuit 1134 are arranged adjacent to the data line 112. It can be understood that this arrangement makes the gap between the adjacent first pixel electrode 1131 and the second pixel electrode 1132 have a larger remaining space on the side away from the same data line 112, and the first extension portion 113b can extend more toward the second pixel electrode 1132, and the second extension portion 113d can also extend more toward the first pixel electrode 1131, thereby further increasing the proportion of the area of ​​the first pixel electrode 1131 and the second pixel electrode 1132.

[0044] It is understandable that in other possible implementations, the first driving circuit 1133 and the second extension portion 113d can be arranged adjacent to the data line 112, and the second driving circuit 1134 and the first extension portion 113b can be arranged away from the same data line 112, that is, the first driving circuit 1133 and the second driving circuit 1134, the first extension portion 113b and the second extension portion 113d are respectively arranged diagonally cross-arranged. As long as it does not affect the increase in the proportion of the area of ​​the first pixel electrode 1131 and the second pixel electrode 1132, the present application does not limit the arrangement of the first driving circuit 1133, the second driving circuit 1134, the first extension portion 113b and the second extension portion 113d.

[0045] In a possible implementation, please refer to Figure 3 , Figure 3 for Figure 2 The display panel 1 further comprises a color filter substrate 12, which is stacked with the array substrate 11, and a plurality of first common electrodes 121 and a plurality of second common electrodes 122 are arranged on one side of the color filter substrate 12 adjacent to the array substrate 11, the first common electrodes 121 and the second common electrodes 122 are arranged alternately and at intervals, the orthographic projection of the first common electrode 121 on the array substrate 11 covers the first pixel electrode 1131, the orthographic projection of the second common electrode 122 on the array substrate 11 covers the second pixel electrode 1132, the first common electrode 121 is used to receive a first voltage signal, the second common electrode 122 is used to receive a second voltage signal, and the voltage values ​​of the first voltage signal and the second voltage signal are different.

[0046] It should be noted that, for the array substrate 11, the first driving circuit 1133 drives the first pixel electrode 1131 to operate, and the second driving circuit 1134 drives the second pixel electrode 1132 to operate, thereby realizing a four-domain structure design of the pixel electrode in the display panel 1, that is, independent driving display of four situations of the first pixel electrode 1131 and the second pixel electrode 1132 can be realized.

[0047] In combination with the working principle of the display panel 1, in this embodiment, the orthographic projection of the first common electrode 121 on the array substrate 11 covers the first pixel electrode 1131, and the orthographic projection of the second common electrode 122 on the array substrate 11 covers the second pixel electrode 1132, and the voltage values ​​of the first voltage signal and the second voltage signal are different. In other words, the 8-domain structure design of the pixel electrode in the display panel 1 is realized, that is, the independent driving display of 8 situations of the first pixel electrode 1131 and the second pixel electrode 1132 can be realized.

[0048] In this embodiment, the first voltage signal and the second voltage signal are generated by the driving chip in the display panel 1 and are respectively transmitted to the first common electrode 121 and the second common electrode 122 through the circuit; it can be understood that in other possible embodiments, the first voltage signal and the second voltage signal can also be transmitted to the first common electrode 121 and the second common electrode 122 through the circuit through an external or built-in voltage source, as long as the normal screen display function of the display panel 1 is not affected and the voltage values ​​of the first voltage signal and the second voltage signal are different, the present application does not impose any restrictions on this.

[0049] It is understandable that in the related art, three driving circuits are usually used to drive two pixel electrodes respectively to realize the 8-domain structure design of the pixel electrode in the display panel 1. Specifically, one driving circuit is used to drive one pixel electrode, another driving circuit is used to drive another pixel electrode, and the remaining driving circuit is used to pull down the voltage of one pixel electrode, thereby realizing the design of the 8-domain structure. In this embodiment, by alternately and spacedly arranging a plurality of the first common electrodes 121 and a plurality of the second common electrodes 122 on the color filter substrate 12, the 8-domain structure design of the pixel electrode in the display panel 1 can also be realized while reducing the number of driving circuits, and the available space between the adjacent first pixel electrodes 1131 and the second pixel electrodes 1132 is increased, so that the first pixel electrodes 1131 and the second pixel electrodes 1132 can be extended, thereby increasing the light-transmitting area of ​​the display panel 1, improving the transmittance, and improving the display effect of the display panel 1.

[0050] In a possible implementation, please refer to Figure 4 , Figure 4 A schematic top view of a color film substrate provided in one embodiment of the present application. The display panel 1 further includes a first voltage signal line 13 and a second voltage signal line 14, the first voltage signal line 13 is used to transmit the first voltage signal, the second voltage signal line 14 is used to transmit the second voltage signal, the first voltage signal line 13 is arranged on one side of the color film substrate 12, and is connected in parallel to a plurality of the first common electrodes 121, the second voltage signal line 14 is arranged on the other side of the color film substrate 12, and is connected in parallel to a plurality of the second common electrodes 122.

[0051] Specifically, the first voltage signal line 13 and the second voltage signal line 14 are usually formed by an etching process. Figure 4 As shown, the first voltage signal line 13 is arranged on one side of the color film substrate 12, and the second voltage signal line 14 is arranged on the other side of the color film substrate 12, so that there is no crossing part between the first voltage signal line 13 and the second voltage signal line 14, so that they can be etched through the same mask plate in the same process flow, reducing the process steps.

[0052] In one possible implementation, please refer again to Figure 2 The first driving circuit 1133 includes a first thin film transistor 113e, the gate of the first thin film transistor 113e is the gate line 111, the drain d of the first thin film transistor 113e is electrically connected to the first pixel electrode 1131, and the source s of the first thin film transistor 113e is electrically connected to the data line 112; the second driving circuit 1134 includes a second thin film transistor 113f, the gate of the second thin film transistor 113f is the gate line 111, the drain d of the second thin film transistor 113f is electrically connected to the second pixel electrode 1132, and the source s of the second thin film transistor 113f is electrically connected to the data line 112.

[0053] In this embodiment, the first pixel electrode 1131 is located on one side of the gate line 111, and the second pixel electrode 1132 is located on the other side of the same gate line 111. Figure 2 As shown, the first thin film transistor 113e and the second thin film transistor 113f form a common gate and common source s structure. Specifically, the gate line 111 serves as a common gate of the first thin film transistor 113e and the second thin film transistor 113f, and the common source s of the first thin film transistor 113e and the second thin film transistor 113f is an integrated structure and connected to the data line 112.

[0054] It can be understood that in this embodiment, the first thin film transistor 113e and the second thin film transistor 113f form a common gate and common source s structure, which can reduce the number of wirings, optimize the stacking structure, simplify the layout of the array substrate 11 and the corresponding manufacturing process flow, thereby improving the transmittance of light and improving the display effect.

[0055] In one possible implementation, please refer again to Figure 3 The array substrate 11 includes a substrate 114, a first metal layer 115 disposed on one side of the substrate 114, a second metal layer 116 disposed on a side of the first metal layer 115 away from the substrate 114, a color resist layer 117 disposed on a side of the second metal layer 116 away from the first metal layer 115, and a planar layer 118 disposed on a side of the color resist layer 117 away from the second metal layer 116. The gate line 111 is formed on the first metal layer 115, and at least part of the first driving circuit 1133 and the second driving circuit 1134 are formed on the second metal layer 116. The array substrate 11 also includes a transfer hole 119, and the transfer hole 119 passes through the planar layer 118 and the color resist layer 117, so that the first pixel electrode 1131 and the second pixel electrode 1132 disposed on a side of the planar layer 118 away from the color resist layer 117 are electrically connected to the first driving circuit 1133 and the second driving circuit 1134 respectively through the transfer hole 119.

[0056] It should be noted that if Figure 3As shown, the display panel 1 also includes a liquid crystal layer 15, a support member 16 and a black matrix 17 arranged between the array substrate 11 and the color film substrate 12. The working principle of the liquid crystal layer 15 is described above and will not be repeated here. The support member 16 is used to support the array substrate 11 and the color film substrate 12. At the same time, the support member 16 is also used to limit the flow of the liquid crystal layer 15, and limit the liquid crystal layer 15 to the effective display area of ​​the display panel 1. The black matrix 17 is arranged corresponding to the support member 16 and the adapter hole 119, that is, the black matrix 17 is usually arranged in a non-opening area to block the light emitted by the backlight source and prevent the light emitted by the backlight source from being emitted through the non-opening area, thereby avoiding light leakage of the display panel 1 and improving the contrast of the display panel 1. The color resist layer 117 generally includes a green color resist, a blue color resist and a red color resist, which are respectively used to filter the light emitted by the backlight source into green light, blue light and red light, and then pass through the dimming function of the liquid crystal layer 15 to finally realize the picture display function of the display panel 1. The black matrix 17 is generally also arranged between the green color resist, the blue color resist and the red color resist (not shown in the figure), which is used to separate the green color resist, the blue color resist and the red color resist to avoid the situation of color mixing after filtering. The surface of the flat layer 118 in contact with the first pixel electrode 1131 and the second pixel electrode 1132 is flat, so as to improve the display effect. A first insulating layer 11a is also formed between the first metal layer 115 and the second metal layer 116 to isolate the electrical connection between the first metal layer 115 and the second metal layer 116, and a second insulating layer 11b is also arranged between the second metal layer 116 and the color resist layer 117 to isolate the electrical connection between the second metal layer 116 and the color resist layer 117. In this embodiment, the transfer hole 119 also penetrates the first insulating layer 11a and the second insulating layer 11b, so that the first pixel electrode 1131 or the second pixel electrode 1132 can be electrically connected to the drain d of the first driving circuit 1133 or the second driving circuit 1134 respectively through the transfer hole 119.

[0057] Specifically, the transfer hole 119 is opened in the flat layer 118 and the color resist layer 117; the first pixel electrode 1131 or the second pixel electrode 1132 is electrically connected to the first driving circuit 1133 or the second driving circuit 1134 respectively through the transfer hole 119, which reduces the number of wirings, optimizes the stacking structure, further improves the transmittance of light, and improves the display effect.

[0058] It can be understood that, since the area occupied by the non-light-transmitting region in the display panel 1 is relatively small, the area through which the first pixel electrode 1131 and the second pixel electrode 1132 pass can be increased, thereby increasing the light transmittance and improving the display quality.

[0059] In one possible implementation, please refer again to Figure 2 The display panel 1 further includes a third common electrode 18, which is respectively disposed on both sides of the gate line 111 and extends along the first direction D1, and the orthographic projections of the third common electrode 18 and the data line 112 on the array substrate 11 at least partially overlap.

[0060] Specifically, the third common electrode 18 is formed on the first metal layer 115, and is respectively disposed on both sides of the gate line 111, and extends along the first direction D1, so as to at least partially overlap with the orthographic projection of the data line 112 on the array substrate 11. It can be understood that the third common electrode 18 is used to receive a third common voltage signal, and the overlapping portion of the third common electrode 18 and the data line 112 can reduce the interference of the data signal transmitted on the data line 112 to the first pixel electrode 1131 or the second pixel electrode 1132 located on the same side as the third common electrode 18 through the coupling effect of capacitance.

[0061] This application also provides a method for preparing a display panel, please refer to Figure 5 , Figure 5 A schematic flow chart of a method for preparing a display panel provided in one embodiment of the present application. The method for preparing a display panel comprises steps S501, S502, S503, S504, S505, S506, S507, and S508, wherein steps S501, S502, S503, S504, S505, S506, S507, and S508 are described in detail as follows.
