Display device

Abstract

The invention provides a display device comprising a display panel and a chip on film connected to the display panel, wherein the display panel comprises a display area and a non-display area surrounding the display area; the display area is provided with a plurality of spaced data lines; the chip on film is provided with a source driving chip and a plurality of fan-out wires connected to the source driving chip at one ends; the other ends of the plurality of fan-out wires are respectively connected to the plurality of data lines correspondingly, and the plurality of fan-out wires form a sector-shaped area. Equivalent to setting the fan-out area of the prior art on the chip on film, the portion near the chip on film of the non-display area of the display panel can be made narrower to achieve an ultra-narrow border of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Thin Film Transistor (TFT) is the main driving element in current Liquid Crystal Display (LCD) and Active Matrix Organic Light-Emitting Diode (AMOLED). It is related to the display performance of the flat panel display device. [0003] Most of the liquid crystal displays currently on the market are backlight 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 pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter (ColorFilter, CF) substrate, and apply pixel voltage on the two substrates respectively. and the common voltage, through the electric field formed between the pixel voltage and the common voltage to control...

Problems solved by technology

However, there are two problems in the existing fan-out area 100'. First, the fan-out area 100' is located in the non-display area 201' of the display panel 200'. Due to the existence of the fan-out area 100', the display panel 200' cannot achieve narrow border, secondly, in the fan-out area 100', the fan-out traces 101' located in the middle area of ​​the fan-out area 100' are relatively short, and the fan-out traces 101' located on both sides of the fan-out area 100' are relatively long, resulting in The impedance of the fan-out wiring 101' in the two sides of the out area 100' is higher than the impedance of the fan-out wiring 101' in the middle area, so that the data lines 203' transmitted to the areas on both sides of the display area 202' of the display panel 200' Compared with the signal attenuation of the data line 203' transmitted to the middle area of ​​the display area 202', the signal attenuation is serious, which eventually leads to a serious insufficient charging problem in the areas on both sides of the display area 202' compared with the middle area, which is visually manifested as color shift
