GOA circuit

Abstract

The invention provides a GOA circuit, which comprises a plurality of cascaded GOA units, wherein the n-th GOA unit comprises a pull-up control circuit unit (101), a pull-up circuit unit (102), a download circuit unit (103), a pull-down circuit unit (104), a pull-down holding circuit unit (105) and a bootstrap capacitor (106). By dividing the bootstrap capacitor into a plurality of first capacitorswhich are connected in parallel, a connecting line of a first capacitor and the GOA circuit is cut off after the function of the first capacitor is lost due to a small-particle foreign matter or damage of an insulating layer, the, the function of the whole bootstrap capacitor does not fail, and the function loss of the GOA circuit caused by the failure of the whole capacitor due to the small-particle foreign matter is avoided.

Description

technical field [0001] This application relates to the field of display technology, in particular to a GOA circuit. Background technique [0002] In the existing display panel technology, with the popularization and deepening of the application of the GOA circuit, in order to improve the transmission efficiency of the clock signal, the designed capacitor is precharged and pulled up, so as to quickly pull up the output n-level signal potential, and the general design of the capacitor is general It is formed as a whole block of first metal layer (M1), second metal layer (M2) and insulating layer interposed therebetween. [0003] With the development of the panel industry, cost reduction is the key to improving product competitiveness, and the insulating layer tends to be thinner. In addition, in the actual production process, fine particles and film breakage will occur during the film formation process, which will lead to capacitor failure and affect GOA function, resulting i...

Problems solved by technology

[0003] With the development of the panel industry, cost reduction is the key to improving product competitiveness, and the insulating layer tends to be thinner. In addition, in the actual production process, fine particles and film breakage will occur during the film formation process, which will lead to capacitor failure and affect GOA function, resulting in product scrapping

[0004] Therefore, the present invention provides a GOA circuit to solve the problems of fine particles and film rupture leading to capacitor failure during film formation.
