Abstract
A liquid crystal display and a repair lines structure thereof are provided. In the liquid crystal display, an amplifier is disposed inside an integrated circuit chip, such as a data driver or a scan driver. The amplifier is serially connected to the signal line via a repair line by means of an appropriate connection circuit. Consequently, the problem of signal attenuation occurring in the repair line will be improved.
Claims19
A liquid crystal display, comprising:
- a display panel having a plurality of signal lines;
- at least one internal repair line formed on the display panel and crossed over the plurality of signal lines;
- at least one repair line, at least part of the repair line being formed on the display panel and crossed over the plurality of signal lines;
- at least one integrated circuit chip electrically connected to the signal lines, the integrated circuit chip comprising:
- at least one first amplifier having an input end selectively electrically connected to the at least one internal repair line, and an output end selectively electrically connected to the at least one repair line;
- and
- a connection circuit formed on the display panel, the connection circuit comprising:
- at least one first portion electrically connected to the output end of the at least one first amplifier and crossed over the at least one repair line;
- and
- at least one second portion electrically connected to the input end of the at least one amplifier and crossed over the at least one internal repair line.
