Abstract

The invention discloses a liquid crystal display (LCD) testing jig. The LCD testing jig is characterized by comprising a base, a carrying table, a camera fixed at the top of a camera obscura, a signal transmission module and an automatic detecting system, wherein the base and the carrying table are sequentially arranged in the camera obscura from bottom to top. The base is fixedly connected with the carrying table. The signal transmission module is electrically connected with an LCD to be detected. The automatic detecting system is electrically connected with the camera and receives an image signal transmitted by the camera. The LCD testing jig has the advantages of being simple in structure and convenient to operate, shooting the whole LCD displaying process through the camera, being capable of quickly judging product quality, enabling detected results to be accurate, stable and reliable, reducing the reject ratio of finished products, utilizing the automatic detecting system to perform detection, enabling the detection speed to be high and greatly improving the work efficiency.

Description

technical field [0001] The invention relates to a test fixture, in particular to a test fixture for testing LCDs. Background technique [0002] With the continuous development of flat panel display technology, LCD is widely used in various Electronic products, such as computers, automotive peripheral electronic equipment, mobile phones, netbooks, MP4, MP5, etc., all products that include LCD displays. Usually, before the packaging process, the LCD screen will be tested for lighting and other tests, and the test signal will be generated by the test fixture, and then the signal will be transmitted to the LCD screen, so that the LCD screen will start to emit light. Existing LCD test fixtures mainly use experienced personnel to judge whether the content displayed on the LCD screen is correct, whether the brightness is sufficient, and whether the finished product is tilted by using manual visual methods. It is risky, and the work efficiency is low, and the detection results lac...
