Problems solved by technology

And when the width of the signal traces is designed too narrow (easy to overheat, and may be difficult to manufacture and have yield problems), or when the signal traces are too close to each other (mutual interference of electrical signal transmission), it may also affect the signal traces. The quality of the signal transmitted by the line is seriously affected

Abstract

The invention discloses a display device, which includes a display panel, a first signal wiring layer, a second signal wiring layer and a third signal wiring layer. Wherein, the first signal wiring layer, the second signal wiring layer and the third signal wiring layer are arranged in a frame area around the display panel. Moreover, the first signal routing layer, the second signal routing layer and the third signal routing layer are respectively located at different levels. Wherein the first signal wiring layer, the second signal wiring layer and the third signal wiring layer are used for transmitting control signals to the display panel.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device and its signal routing design. Background technique [0002] In the current market, liquid crystal displays are widely used in computer screens, mobile phones, personal digital assistants (PDAs), tablet computers, e-books, flat-screen TVs, etc. on electronic products. [0003] The working principle of the liquid crystal display is to change the alignment state of the liquid crystal molecules in the liquid crystal layer by changing the voltage difference between the two ends of the liquid crystal layer to change the light transmittance of the liquid crystal layer, and then cooperate with the light source provided by the backlight module to display images. Generally speaking, a display device includes a display area where a display panel is disposed and a surrounding frame area. Currently, the driving circuits of display panels are mostly divided into source driver...
