Problems solved by technology

[0005] Although this detection method can determine the reason why the liquid crystal display A1 cannot display images normally, it requires manpower to reinstall another driver integrated circuit chip A121 on the machine, which not only causes waste of manpower, machine and driver integrated circuit chip A121, but also The entire test process takes a considerable amount of time, which in turn makes the test cost of LCD A1 high
Therefore, how to improve the testing method of the liquid crystal display A1 to reduce the waste caused by reinstalling another driver integrated circuit chip A121, and then solve the shortcoming of the high test cost of the liquid crystal display A, is an urgent problem to be solved

Abstract

The invention reveals a LCD panel detecting method and device for detecting LCD panel comprising ICs and display unit and the method comprises the steps of: removing ICs; placing the LCD panel on a detection platform; using a probe to contact line defect position of the LCD panel; guiding the tested signal through the probe to the display unit; and determining the detection result according to the image signal outputted by the display unit to determine whether the display unit is good or not.

Description

technical field [0001] The present invention relates to a detection method and device, in particular to a detection method and device for detecting a liquid crystal panel. Background technique [0002] With the rapid progress and evolution of display technology, the traditional cathode ray tube (CRT) display has been gradually eliminated, and replaced by a light, thin, short and small liquid crystal display (LCD). Due to the advantages of high display quality, low energy consumption and no radiation, liquid crystal displays are widely used in mobile phones, personal digital assistants (PDAs), notebook computers, digital cameras, digital cameras, computer screens and LCD TVs, etc. in communications, information or consumer electronics. [0003] FIG. 1 is a conventional liquid crystal display A1, which includes a liquid crystal display unit (cell) A11, a tape automated bonding technology (TAB), a die glass bonding technology (chip onglass, COG) or a die soft mold A plurality...
