Embodiment Construction
[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0030] In the LCD display with 1 scanning line and 2 data lines (1G2D) driving mode, one scanning line (GateLine) can control two rows of pixels at the same time, and the number of data lines (DataLine) is twice that of the normal mode.
[0031] In the embodiment of the present invention, an anti-ESD structure based on a 1G2D driving mode is designed, and the anti-ESD structure is arranged between two adjacent data lines.
[0032] like figure 2 As shown, in the liquid crystal display, a plurality of pixel units are regularly arranged in the row direction and the column direction, and a plurality of data lines, each data line is electrically connected to a plurality of pixel units located in the same column, and the same column There is a data line on b...

An embodiment of the invention provides an anti-static liquid crystal display and a manufacture method thereof. The liquid crystal display comprises a plurality of pixel units, a plurality of data lines and a plurality of anti-static breakdown structures, wherein the plurality of pixel units are regularly arranged in a row direction and a line direction, the plurality of pixel units on one line correspond to two data lines, the plurality of pixel units on a same line are alternately and electrically connected with one of the two data lines corresponding to the line of the pixel units, and the plurality of anti-static breakdown structures are arranged between two adjacent data lines. A first through hole and a second through hole are arranged on a first data line to enable an active layer, a data line metal layer and a grid electrode metal layer to form a thin film transistor (TFT) switch, and the TFT switch can be connected to lead static charges on the first data line in the adjacent data line through the active layer to release when big static charges form. An electro-static discharge (ESD) prevention structure is located in an effective display area rather than a frame position so that size of the liquid crystal display can be reduced.
Description
technical field [0001] The invention relates to liquid crystal screen technology, in particular to an antistatic liquid crystal display screen and a manufacturing method thereof. Background technique [0002] In the process of manufacturing the liquid crystal panel, static electricity will cause many defects, so the design of the anti-static breakdown (ESD, electrostatic discharge) structure of the liquid crystal display panel is very important. The anti-ESD circuit is generally designed around the effective display area (ActiveArea) and occupies a certain space. At present, narrow bezel and ultra-narrow bezel panels have become the mainstream of liquid crystal display products, and due to the characteristics of narrow bezel products, the space between the effective display area and the edge of the panel is required to be very small, such as figure 1 As shown, the area for accommodating the pixel matrix is the effective display area, and the area between the effective dis...
