Display panel and display module

Abstract

The invention provides a display panel and a display module. The display panel includes a display area, a driving chip located on one side of the display area, and a fan-out trace area connecting thedisplay area and the driving chip. The driving chip includes a first side, and two second sides vertically connected to two ends of the first side, respectively. The fan-out trace area includes a plurality of first fan-out traces connected to the first side, and a plurality of second fan-out traces respectively connected to the two second sides. According to the display panel and the display module, several signals of the driving chip are transmitted from the second sides at the two sides of the driving chip to the display area through the plurality of second fan-out traces, thereby increasingthe total width of the fan-out trace area so as to increase the width of the traces in the fan-out trace area to avoid the risk of trace breakage and reduce the impedance of the traces.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display module. Background technique [0002] Thin Film Transistor (TFT) is the main driving element in current liquid crystal display (Liquid Crystal Display, LCD) and Active Matrix Organic Light-Emitting Diode (AMOLED), directly It is related to the display performance of the flat panel display device. [0003] Most of the liquid crystal displays on the current market are backlit liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to inject liquid crystal molecules between the ThinFilm Transistor Array Substrate (TFT Array Substrate) and the Color Filter (CF) substrate, and apply pixel voltages on the two substrates. And the common voltage, the rotation direction of the liquid crystal molecules is controlled by the electric field formed between the pi...

Problems solved by technology

Due to the continuous improvement of the current display screen ratio, the lower border of the display panel (lower border) is getting smaller and smaller, resulting in the panel connecting the output pin (output pin) of the interlace integrated chip (Interlace IC) and the display (Active Area, AA) The space of the metal fan-out (Fanout) routing of the touch signal line and the data signal line in the area is reduced (interleaved integrated chip refers to a type of IC with embedded touch drive function, the order of the output pins of this type of IC The output pins of the data signal and the output pins of the touch signal are alternately wired according to a certain rule), which leads to the reduction of the line width of the metal fan-out line, which is prone to breakage of the metal fan-out line and affects the touch function of the panel
