Description

A kind of GOA array base paltes and display device

【Technical field】

The present invention relates to liquid panel technique field, more particularly to a kind of GOA array base paltes and display device.

【Background technology】

In display technology field, panel display apparatus, such as liquid crystal display (Liquid Crystal Display, LCD) There is light, thin, low work(because of it with display of organic electroluminescence (Organic Light Emitting Display, OLED) Consumption, high brightness, and the advantages of high image quality, in technical field of flat panel display consequence is occupied.Display device at least includes The array base palte of pel array is provided with, usually, the viewing area of array base palte is provided with scan line, data wire, Yi Jiwei Pixel electrode in pixel region etc., also including peripherally located region or the gate driver circuit on circuit board and source drive electricity Road.

At present general employing prepares raster data model (Gate Driver On Array, GOA) technology system on array base palte Standby display base plate, GOA circuits are referred to and directly prepare the scan line drive circuit on array base palte.GOA circuits include it is multistage according to The shift register of secondary connection, each shift register drives a scan line, and provides unlatching for next stage shift register Signal, so as to GOA circuits are capable of achieving on the whole the purpose that makes scan line open line by line.GOA technologies compare traditional handicraft, not only save Cost has been saved, simultaneously because the binding technique on grid direction can be saved, it is extremely advantageous to lifting production capacity, and improve liquid crystal The integrated level of display floater.For large size panel, due to its RC loading (load) it is larger, it is typically electric using bilateral GOA Road drives, i.e., be equipped with GOA circuits in array base palte both sides, together each horizontal scanning line in driving panel.When GOA circuits certain When there is the failures such as short circuit, disconnection in individual position, can by causing trouble position after shift register cisco unity malfunctions at different levels, And then cause to show abnormal.In array base palte production process, when the functional module existing defects on array base palte, showed Occur in journey various relevant with array base palte bad.For example, the display that scan line or broken data wire cause is bad, grid The display that drive circuit or source electrode drive circuit defect cause is bad.Therefore, the bad of array base palte to completing is carried out Accurately detect extremely important, bad detection and the reliability analyzed are extremely important.

Due to the RC (resistance and electric capacity) of large scale display floater load it is larger, in order to reduce the load of GOA cascade circuits, Multiple CK can typically be adopted, and (CK quantity is=2N, and N is positive integer and N >=2).The GOA circuits of such as 8CK, will be by entire surface The load of plate is divided into 4 parts, shares in 4 groups of GOA circuits.And CK sums are the GOA cascade circuits of 2a, front N levels element circuit Pulling drive module is to be connected to STV open signals.
