Abstract

The invention discloses a liquid crystal display array substrate, a source electrode circuit and a broken line repairing method. The array substrate comprises grid lines, data lines and two or more than two repairing circuits. The grid lines are arranged on a base parallelly and used for transmitting scanning signals to a display panel. The data lines are arranged on the base on the layers different from those of the grid lines, are perpendicular to the grid lines in the moving direction and are used for transmitting source electrode driving signals to the display panel. The repairing circuits are arranged on the base and comprise a first group of terminals and a second group of terminals. The first group of terminals are idle, so that one of the terminals in the first group is short-circuited with the output end of a certain data line in the data lines when break points occur on the data line. The second groups of terminals are connected with the output ends of a source electrode driving circuit, when a Souce integrated circuit (IC) obtains a broken line repairing control signal, a driving signal same as the input end of the data line with break points is output to the second group of the terminals, and the repairing circuits connect the circuit. The repairing circuit is simple in design and repairing method, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display array substrate, a source drive circuit and a disconnection repair method. Background technique [0002] In today's flat panel display technology, liquid crystal display (LCD) can be said to be the most mature technology, especially TFT-LCD. The liquid crystal display includes array substrates designed in a matrix form, and driving circuits for driving these array substrates. The deflection of liquid crystal molecules is realized through the change of the electric field in the liquid crystal cell, so as to achieve the display effect. [0003] With the development of semiconductor technology, the size of TFT devices is getting smaller and smaller, and the resolution of LCD is getting higher and higher, so the metal line width is required to be narrower and narrower. For the current technology level, the direct risk of narrowing the line wi...
