Abstract

The invention provides an array detection circuit, a driving method, a display driver, a display substrate and a device. The array detection circuit comprises a first detection unit for controlling the output end of GOA units on the odd-numbered lines to be connected with a first detection control wire under the control of a first detection control signal output by the first detection control wire and controlling the output ends of the GOA units on the even-numbered lines to be connected with a first level wire, and a second detection unit for controlling the output ends of the GOA units on the even-numbered lines to be connected with a second detection control wire under the control of a second detection control signal output by the second detection control wire and controlling the output end of the GOA units on the odd-numbered lines to be connected with the first level wire. The array detection circuit can fulfill the aim of respectively starting grid wires on the odd-numbered lines and wires lines on the even-numbered lines, and the disqualification detection rate of array detection can be increased favorably.

Description

technical field [0001] The present invention relates to the technical field of array detection, in particular to an array detection circuit, a driving method, a display driver, a display substrate and a device. Background technique [0002] Currently designing low-cost, narrow-frame products is the development trend of the LCD panel industry. GOA (Gate Driver On Array), is a gate line driver circuit on the TFT substrate, which can replace the function of Gate IC (gate driver), which reduces the cost and is more conducive to the realization of narrow frame design. The current GOA products are generally divided into Normal Pattern (standard mode) and GOA Pattern when performing AT (Array Test, array test). (GOA Pattern refers to the GOA signal timing of inputting actual design when AT, verifies the function of GOA area with this, is not the aspect that the present invention relates to, repeats no more.) Normal Pattern is adopted when AA (effective display area) area is detect...
