Problems solved by technology
In the display panel industry, electrostatic discharge (ESD) is an important parameter that affects the qualification rate and reliability of display products. For narrow-frame display panels, as the frame becomes narrower and narrower, the space reserved for electrostatic discharge becomes more and more The smaller it is, the static electricity will slowly accumulate without being released, making the electrostatic discharge phenomenon it faces will be more serious, which will eventually affect the yield of the product

The invention provides a liquid crystal displayer and a display panel thereof. The display panel comprises a PCB, a TFT substrate, a liquid crystal layer and a color filter, wherein the TFT substrate, the liquid crystal layer and the color filter are sequentially arranged on the PCB. The display panel is characterized in that an ITO layer is arranged on the lower surface of the color filter, a grounding region is arranged on the PCB, and the ITO layer is electrically connected with the grounding region. According to the liquid crystal displayer and the display panel thereof, the ITO layer and the grounding region are electrically connected to form an electrostatic discharge path of the display panel, and the problem of electrostatic discharge is solved while a narrow border of the display panel is achieved, the qualification rate of the display panel is increased, and reliability of the display panel is promoted.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display and a display panel thereof. Background technique [0002] Liquid crystal display is a very common technology used in modern displays. With the continuous development of liquid crystal displays, the market demand for display panels with narrow borders is increasing. In the display panel industry, electrostatic discharge (ESD) is an important parameter that affects the qualification rate and reliability of display products. For narrow-frame display panels, as the frame becomes narrower and narrower, the space reserved for electrostatic discharge becomes more and more The smaller it is, the static electricity will slowly accumulate if it is not released, so that the electrostatic discharge phenomenon it faces will be more serious, which will eventually affect the yield of the product.
