Description

Technical Field

[0001] The invention relates to a display panel. Background Art

[0002] Touch screen technology has brought a new era to mobile phones and tablets, and is widely used in notebooks, desktop monitors, and all-in-one computers. To turn a display into a "touchpad", it is necessary to combine two completely different functions: display and touch. In the past, touch sensors were added to the display by "lamination". Recent technology has developed embedded displays that integrate touch sensors directly into the display. However, the touch signal lines configured in the pixel array layer can cause problems such as color difference, dark state leakage, and reduced contrast at front and side viewing angles. Summary of the invention

[0003] The present invention provides a display panel, in which the reflected light from each signal line will not cause color difference at a side viewing angle, and the problems of dark state light leakage and reduced contrast at a front viewing angle / side viewing angle are avoided.

[0004] According to one embodiment of the present invention, a panel is provided, comprising a substrate, a pixel array layer and a color resist layer. The substrate has a surface. The pixel array layer is disposed on the surface and comprises a plurality of signal lines arranged along a first direction. The color resist layer is disposed on the pixel array layer and comprises a plurality of pixel units. The pixel units are arranged in sequence along the first direction, and each pixel unit comprises a plurality of color resists, and the color resists of each pixel unit comprise a first color resist, a second color resist and a third color resist arranged in sequence along the first direction, wherein the colors of the first color resist, the second color resist and the third color resist are different. Each signal line corresponds to the boundary between the first color resist and the second color resist, the boundary between the second color resist and the third color resist, or the boundary between the third color resist and the first color resist. The gap between two adjacent signal lines corresponds to N color resists, where N is a positive integer greater than 1, and N is not a multiple of 3.

[0005] According to another embodiment of the present invention, a panel is provided, comprising a substrate, a pixel array layer and a color resist layer. The substrate has a surface. The pixel array layer is disposed on the surface and comprises a plurality of signal line groups arranged along a first direction, each signal line group comprises M signal lines arranged along the first direction, and M is a positive integer greater than 1. The color resist layer is disposed on the pixel array layer and comprises a plurality of pixel units, the pixel units are arranged in sequence along the first direction, and each pixel unit comprises a plurality of color resists, the color resists of each pixel unit comprise a first color resist, a second color resist and a third color resist arranged in sequence along the first direction, wherein the colors of the first color resist, the second color resist and the third color resist are different. Each signal line corresponds to the boundary between the first color resist and the second color resist, the boundary between the second color resist and the third color resist, or the boundary between the third color resist and the first color resist. The gap between two adjacent ones of the M signal lines in each signal line group corresponds to one color resist. The gap between two adjacent ones of the signal line groups corresponds to N color resists. The sum of M and N is a positive integer greater than 3, and the sum of M and N is not a multiple of 3.

[0006] Based on the above, the display panel provided by the embodiment of the present invention has a special signal line configuration, which does not require a signal line to be configured at each color resistance junction, thereby avoiding dark state light leakage and reduced contrast at front viewing angle / side viewing angle, and does not cause color difference at side viewing angle due to reflection of each signal line.
