A kind of GOA circuits and array base palte, liquid crystal panelTechnical field
The present invention relates to a kind of display technology field, particularly a kind of GOA circuits and liquid crystal panel.
Background technology
Liquid crystal display is very conventional technology in modern display.In the manufacture process of liquid crystal panel or use processIn can usually produce electrostatic, damage by static electricity can cause the abnormal of panel even to fail, therefore to the design of electrostatic defending in panelIt is very important in design.
At present, GOA technologies are used widely in TFT-LCD manufactures field, GOA (Gate Driver onArray, array base palte row drive) technology refers to and for the gate drivers (Gate Driver) of TFT-LCD to be integrated in array base palteOn, form the turntable driving of counter plate.
Yet with its circuit connection and the complexity of technique, the yields of GOA circuits is very low, wherein, affects its non-defective unitOne principal element of rate is accumulation of static electricity and ESD (Electro-Static discharge, Electro-static Driven Comb), existingIn the manufacture process of GOA circuits, due to STV (Vertical Start Pluse, frame unbalanced pulse signal) holding wire it is longer,Substantial amounts of electric charge is accumulated in plasma gas-phase deposit environment easily, and it is easy when these electric charges are discharged to the inside of GOA unitCause GOA unit by the generation of electrostatic breakdown phenomenon, the GOA unit short circuit for causing, make GOA circuits cannot normal work, so as toCause the display device cannot normal display picture.STV holding wires can also be injured when there is damage by static electricity, causing GOA to fail, itsIn be easiest to be wounded is then outermost STV holding wires.

Specific embodiment
With reference to the accompanying drawings and examples the present invention is described in further detail.
STV holding wires 1 general in prior art are generally arranged at the outermost of GOA circuits, are so highly susceptible to quietElectric burn.
In the present invention, STV holding wires 1 include but is not limited to this, and defined herein STV holding wires are only for the purposes of to the present inventionMiddle position relationship is described, and the inventive point of the present invention is only to need to arrange electrostatic on an outermost STV holding wirePreventer.
A kind of GOA circuits of the present invention, at least one STV holding wire being connected including GOA unit and with GOA unit,Electrostatic protection apparatus are provided between the STV holding wires 1 and the source ground holding wire 2 of GOA unit or array base palte.
It is illustrated in figure 1 the GOA circuits of the embodiment of the present invention 1, figure acceptance of the bid shows two STV holding wires 1, wherein oneFor STV_D2U signal input lines 8 (for being scanned from bottom to up, i.e., counter to sweep), another is STV_U2D signal input lines 9(for being scanned from top to bottom, i.e., just sweeping), it is electric that the STV_U2D signal input lines 9 in the STV holding wires 1 are arranged on GOAOutermost in road is adjacent with source ground holding wire (GND) 2 of array base palte, is arranged on outermost and source ground signalAt least one standby STV letter being connected with GOA unit by cross-over mode is drawn on the adjacent STV_U2D signal input lines 9 of line 2Number line (STV_U2D signal input lines) 3, so as to space signal input can be provided when outermost STV holding wires wound,Can prevent GOA circuits it is positive and negative sweep failure live GOA unit failure problem.
It is illustrated in figure 2 the GOA circuits of the embodiment of the present invention 2, figure acceptance of the bid shows two STV holding wires 1, wherein oneFor STV_D2U signal input lines 8 (for being scanned from bottom to up, i.e., counter to sweep), another is STV_U2D signal input lines 9(for being scanned from top to bottom, i.e., just sweeping), it is electric that the STV_U2D signal input lines 9 in the STV holding wires 1 are arranged on GOAOutermost in road is adjacent with source ground holding wire (GND) 2 of array base palte, and the STV_U2D signal input lines 9 are connect with source electrodeElectrostatic protection apparatus are provided between earth signal line (GND) 2, and the electrostatic protection apparatus include nesa coating 4, as shown in figure 3,The nesa coating 4 is connected with STV_U2D signal input lines 9 and source ground holding wire 2 and turns on and formed electric capacity 10, instituteState between nesa coating 4, STV_U2D signal input lines 9 and source ground holding wire 2 by the first passivation on array base palteLayer 12 insulate, and is located between ILD (inter-level dielectric) in the via of insulating barrier 13 in source ground holding wire 2, insulating barrier 13 between ILDOn gate insulator 14；By the electric charge accumulated on outermost STV holding wires 1 is led by source ground holding wire 2Go out, so as to protect to STV holding wires, prevent the damage by static electricity that accumulation of static electricity is caused.
