Description
Technical field
The present invention relates to display technology field, more particularly to a kind of anti-static circuit and liquid crystal display panel.
Background technology
With the development of flat panel display, high-resolution, high-contrast, high refresh rate, narrow frame, slimming into
For the trend of FPD development.At present, liquid crystal display panel (Liquid Crystal Display, LCD) still shows for flat board
The main product shown.
Liquid crystal display panel is generally by a color membrane substrates (Color Filter, CF), a thin-film transistor array base-plate
(Thin Film Transistor Array Substrate, TFT Array Substrate) and one it is filled in two substrates
Between liquid crystal layer formed, its operation principle is by a series of drive signal, such as scanning signal, data-signal, common electrical
Signal etc. is pressed, applies driving voltage on color membrane substrates and array base palte to control the rotation of liquid crystal molecule in liquid crystal layer, controls
The output quantity of light, so as to produce display picture.
In order to realize the narrow frame of liquid crystal panel, slimming and low cost, with original array system of liquid crystal display panel
The drive circuit of scan line is produced on the GOA technologies on the array base palte around liquid crystal display panel effective display area by journey
(Gate Driver on Array) relative maturity.
Please refer to Fig. 1 and Fig. 2, existing GOA circuits generally comprise multiple GOA units 100 of cascade, per one-level
GOA unit 100 include pull-up control module 101, pull-up module 102, drop-down module 103, first pull down maintenance module 104,
Second drop-down maintenance module 105 and bootstrap capacitor 106.If n is positive integer, n-th grade of GOA unit 100 is electrically connected with nth bar and swept
