Embodiment Construction

[0027] The specific implementation manner of the present invention will be described in detail below with reference to the drawings and embodiments.

[0028] Terms such as horizontal direction, vertical direction, and end in the embodiments are directions relative to the positions of the pictures, and should not be construed as limiting the present invention.

[0029] Such as figure 2 A schematic diagram of an electrostatic protection structure formed by two GND metal wires 11 in the present invention is shown. Two adjacent GND metal wires 11 are arranged in one row and two columns, the direction along the row is the second direction, the first direction is perpendicular to the second direction, and the GND metal wires of two adjacent columns have a In the first gap 27, the two ends of the adjacent two sides of the GND metal traces 11 in two adjacent columns are connected through the third metal trace 23, thereby connecting the two GND metal traces 11 into one body, and at t...

Abstract

The invention provides an electrostatic protection structure of a liquid crystal panel by aiming at the problem that static electricity cannot be well released when electrostatic voltage of a GND metal routing is extremely high in the prior art. The electrostatic protection structure of the liquid crystal panel comprises a plurality of arrayed GND metal routings, wherein two adjacent sides of every two adjacent GND metal routings are respectively connected with a third metal routing or a fourth metal routing; each GND metal routing at each of four corners of a GND metal routing array is connected with a second metal routing arranged at the periphery of the array through a fifth metal routing or a sixth metal routing, so that all the metal routings are connected to form a large GND network, and the electrostatic tolerance voltage is increased to a certain extent; and meanwhile, the third metal routing and the fourth metal routing are doped polycrystalline silicon, so that the release of the static electricity is accelerated, and the static electricity release time is shortened.

Description

technical field [0001] The invention relates to the field of liquid crystal panels, in particular to an electrostatic protection structure of a liquid crystal panel. Background technique [0002] Low-temperature polysilicon has the advantage of high mobility, so when designing pixels, the W / L of the thin-film transistor TFT switch can be designed very small, so that the aperture ratio corresponding to the pixel is relatively high, so low-temperature polysilicon liquid crystal panels have great market competitive advantage. [0003] TFT-LCD can be divided into polysilicon (Poly-Si TFT) and amorphous silicon (a-Si TFT), the difference between the two lies in the characteristics of the transistor. The molecular structure of polysilicon is arranged in a neat and directional manner in a grain (Grain), so the electron mobility is 200-300 times faster than that of disordered amorphous silicon; the so-called TFT-LCD is Refers to amorphous silicon, the technology is mature, and it ...
