Description

Anti-static circuit and liquid crystal display panel
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 Line 300 is retouched, pull-up module 102 therein exports scanning drive signal G (n) to nth bar scan line 300, while output stage passes letter Number ST (n);If m is positive integer, and m is less than n, in addition to the 1st grade to m level GOA units, the pull-up control in n-th grade of GOA unit Module 101 cascades the n-th-m level GOA units, and the scanning drive signal G (n-m) and level for accessing the n-th-m level GOA units pass signal ST (n-m);In addition to 1st grade reciprocal to inverse m level GOA units, the drop-down module 103 in n-th grade of GOA unit cascades the n-th+m levels GOA unit, access the scanning drive signal G (n+m) of the n-th+m level GOA units;And the pull-up in the 1st grade to m level GOA units That control module 101 accesses is the synchronizing signal STV that each two field picture is opened, and 1st grade reciprocal into inverse m level GOA units Drop-down module 103 accesses is synchronizing signal STV that each two field picture is opened, if for example, m values are that the 1, the 1st grade of GOA is mono- Pull-up control module 101 in member accesses the synchronizing signal STV that each two field picture is opened, and the 1st grade of i.e. last 1 grade of GOA reciprocal is mono- Drop-down module 103 in member accesses the synchronizing signal STV that each two field picture is opened;If by Fig. 1 and Fig. 2 example, by m value It is set as 2, then the 1st grade of GOA unit accesses the same of each two field picture unlatching with the pull-up control module 101 in the 2nd grade of GOA unit Signal STV is walked, 1st grade reciprocal is accessed each two field picture with the drop-down module 103 in 2nd grade reciprocal i.e. last two-stage GOA unit The synchronizing signal STV of unlatching.
