Abstract

The invention discloses a liquid-crystal display device and a repair method of defects of the liquid-crystal display device. The liquid-crystal display device is provided with a repair ring provided with an open ring. The repair method includes that a data line is connected with a first repair line in an electrical mode; a second repair line is connected with the first repair line in an electrical mode and parts of the first repair line are cut off so that data signals transmitted through the data line are transmitted through a first conductive path which is formed by a first repair line area which is located on one side of the data line and the second repair line next to the data line. Whether the delay and reduction of the data signals transmitted by the first conductive path are in a permissible range or not is judged, if the delay and reduction of the data are in the permissible range, the repair of the data line is completed, otherwise, an open page (OP) is connected on the first conductive path. The liquid-crystal display device is capable of avoiding the use of the OP when the repair ring works, after the repair ring is out of work, the OP is inserted, so that under the circumstances of volume production, the repair success rate is guaranteed, the usage amount of the OP is reduced and the repair cost of the defects of the medium or small sized liquid-crystal display device is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a defect repairing method thereof. Background technique [0002] In recent years, the rapid development of information and communication technology has increased the demand for various types of display devices. Currently common display devices include: cathode ray tube display, liquid crystal display (Liquid Crystal Display, LCD), plasma display, electroluminescent display, and vacuum fluorescent display. Among them, LCD has gradually become the mainstream of display device development due to its high-definition, true-color video display, thin and light appearance, low power consumption, and no radiation. [0003] An LCD generally includes a liquid crystal display panel for displaying pictures and a circuit part for supplying signals to the liquid crystal display panel. The liquid crystal display panel generally includes a firs...
