Display panel, display device, and manufacturing method of display panel

Abstract

The invention relates to a manufacturing method of a display panel. The display panel comprises a substrate, wherein a display area and a peripheral area are arranged on the substrate, the substrate is provided with at least one corner area, and the edge of the corner area extends along a curvature. The manufacturing method comprises the following steps: determining a reference curve according tothe curvature; fitting a broken line according to the reference curve, wherein the broken line is formed by connecting a plurality of broken line segments; and arranging a plurality of circuit units along the broken line, wherein each circuit unit has a length l and a width w, wherein a distance is formed between each broken line segment and the corresponding reference curve, and the distance is smaller than or equal to 50 microns. The invention also provides the display panel prepared according to the manufacturing method and a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display device and a manufacturing method thereof. Background technique [0002] In recent years, with the development of display technology, people have higher and higher requirements on the functionality and aesthetics of display panels. In order to meet the requirements, the design of display panels with special-shaped (such as arc-shaped) corner regions has become more and more popular. s concern. [0003] Display screens with curved corner regions have become a trend. Generally, a display screen with an arc-shaped corner area includes an arc-shaped display area and an arc-shaped peripheral area, and the peripheral area is located at the periphery of the display area. In a display device with an arc-shaped corner region, the wiring method of the peripheral driving circuit becomes complicated, and the wiring method also affects the size of the peripheral ...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the register units are arranged in the hinterland of the arc-shaped corner area in the vertical and horizontal directions along the outer edge of the corner area of ​​the display area. The registers occupy a large space in the hinterland of the arc-shaped corner area. The turns cannot be closely arranged, and there is a certain waste of space, which is not conducive to realizing a narrower frame

At the same time, the connection lines between the registers need to be manually connected, the workload is large and the error rate is high, and the staggered arrangement between the touch control unit (TP switch) and the register unit cannot be realized; the number of register stages set in the arc-shaped corner area is relatively low Fewer lines need to be fanned out in the straight line area, so it is difficult to achieve a narrower border

[0005] The other is as figure 2 As shown, in the hinterland of the arc-shaped corner area, it is rotated and arranged along the outer edge of the corner area. In the layout method, the arc-shaped bus line (bus line) cannot be accurately matched with the TFT devices in the register, and manual trimming is required; the register unit There are many segments, and there will be more manual connections between the segments; the registers at different angles are different units, and it is difficult to adjust and modify later; when the touch control unit (TP switch) is arranged in an arc-shaped corner area, it is difficult to communicate with the Arc bus (busline) with
