Detailed Description

The primary objectives of the present application are: the signal routing is designed to be adjacent to the steps of the two adjacent rows of pixel units in the row direction, so that the gate driving unit is close to the pixel units, and the area of a non-display area is reduced.

Based on the above purpose, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. The features of the various embodiments and embodiments described below may be combined with each other without conflict. It should be further noted that, for the convenience of description, only some of the structures relevant to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic partial structure diagram of a display panel according to an embodiment of the present application. As shown in fig. 1, the display panel 10 includes a display region 11 and a non-display region 12 located at a periphery of the display region.

The display area 11 has at least one row of pixel units 111 arranged in an array. Each pixel unit 111 includes three sub-pixels, for example, an R (Red), a G (Green), and a B (Blue) sub-pixel. Each sub-pixel is capable of displaying a different gray scale under the control of the driving circuit, thereby enabling the display panel 10 to display a color image.

At least one corner of the display area 11 is an arc-shaped corner, and specifically, the display area 11 has at least two adjacent straight edges, and an arc-shaped corner is formed between the two adjacent straight edges. Based on this design, in the area where the arc-shaped corner is located, the display panel 10 has at least two adjacent rows of pixel units 111 with different numbers, for example, in fig. 2, the number of the second row of pixel units 111 is one more than the number of the first row of pixel units 111, so that the two adjacent rows of pixel units 111 form a step. Any two steps may be the same or different in size in the row direction, and the difference between the sizes of the two steps in the row direction is equal to an integral multiple of one sub-pixel in the row direction, which depends on the pixel structure design of the display panel 10. For example, in fig. 2, for the step formed by the first row of pixel units 111 and the second row of pixel units 111 and the step formed by the second row of pixel units 111 and the third row of pixel units 111, the difference between the sizes (i.e., widths) of the two steps in the row direction is equal to the size of one sub-pixel in the row direction.

Driving circuits and traces for driving the sub-pixels to emit light are distributed in the non-display area 12. Specifically, the non-display region 12 includes a Gate driving region (GIP) 121 and a routing region 122. At least one gate driving unit 123 is disposed in the gate driving region 121. The wiring region 122 is disposed closely around the display region 11 and is used to connect the gate driving unit 123 to the corresponding pixel unit 111. Specifically, as shown in fig. 2 or fig. 3, the routing area 122 is provided with a signal routing line 124 and a driving output line 125, the driving output line 125 can be regarded as a connection line extending from the gate driving unit 123, both of which can be disposed in the same layer structure, one end of the driving output line 125 is connected to the gate driving unit 123, the other end of the driving output line 125 is connected to the signal routing line 124, and the signal routing line 124 is connected to the scan line 126 of the driving pixel unit 111, so that the gate driving unit 123 can be used to provide a driving signal to the pixel unit 111 connected thereto.

Each signal trace 124 is connected to one gate driving unit 123, and the signal trace 124 can be regarded as a bridge line, through which the gate driving unit 123 is connected to the corresponding scan line 126. Based on that the driving output line 125 and the signal trace 124 are located at different layers and have insulating layers therebetween, and the scanning line 126 and the signal trace 124 are also located at different layers and have insulating layers therebetween, the driving output line 125 and the signal trace 124, and the scanning line 126 and the signal trace 124 can be connected by through holes, and the through holes are opened in the corresponding insulating layers.

In this application, the signal trace 124 is disposed adjacent to the step of the display area 11, so that the gate driving unit 123 is proximate to the pixel unit 111 as much as possible, that is, the gate driving area 121 is proximate to the display area 11 as much as possible, thereby reducing the area of the non-display area 12, and facilitating the implementation of the narrow-frame design and the narrow-frame display of the display panel 10.

At this time, the second trace 124b can be regarded as a trace extending from the first trace 124a toward the scan line 126.

With reference to fig. 2, the display panel 10 further includes a first electrostatic protection device 129a and a second electrostatic protection device 129b, the first electrostatic protection device 129a is connected to the first trace 124a, and a projection of the second electrostatic protection device 129b and the first electrostatic protection device 129a on the display panel 10 at least partially overlaps.

The capacitance protrudes from the first trace 124a to generate a spike effect, so that the first esd protection device 129a and the second esd protection device 129b can discharge the esd induced on at least one of the signal trace 124 and the scan line 126. Therefore, the first and second

electrostatic protection components

At this time, each row of pixel units 111 is connected to one signal trace 124, and is connected to the corresponding gate driving unit 123 through the signal trace 124.

The signal trace 124 of the present embodiment is equivalent to the first trace 124a in the embodiment shown in fig. 2, and since the signal trace 124 is disposed adjacent to the step at the corner of the arc, the signal trace 124 can be directly connected to the end of the corresponding scan line 126, so the second trace 124b in the embodiment shown in fig. 2 is not required to be disposed in the present embodiment.
