Problems solved by technology
[0005] However, the above-mentioned various detection methods are not effective and efficient in screening.
Because the force of the knocking is not easy to control, not only is it easy to cause uneven force on the LCD panel, but in more serious cases, it may even damage the LCD panel.

The invention discloses a detection device, which is suitable for detecting a liquid crystal panel. The detection device includes a carrier board, a test unit and a light source module. The carrier board is used to carry the liquid crystal panel. The testing unit includes a cavity, a knocking element and a driving element. The chamber has a first chamber and a second chamber, the first chamber and the second chamber are separated, and the first chamber is adjacent to the carrier. The light source module is arranged adjacent to the second chamber, and is used for emitting light, and the light passes through the liquid crystal panel. The knocking element is located in the first chamber, and the driving element is disposed in the second chamber. The knocking element is linked by the driving element, so that the knocking element moves randomly in the first chamber and can strike the liquid crystal panel at multiple points. The device can not only effectively detect defective liquid crystal panels, but also avoid damage to the liquid crystal panels caused by carelessness during the detection process.
Description
technical field [0001] The invention relates to a device for detecting liquid crystal panels, more specifically, to a device for detecting low-temperature liquid crystal bubbles in the liquid crystal panel. Background technique [0002] Due to the advantages of light weight, low power consumption and no radiation pollution, liquid crystal displays are widely used in various electronic consumer products, such as notebook computers, personal digital assistants, mobile phones, etc., and have been widely loved by users . In recent years, liquid crystal displays have even replaced cathode ray tube displays in traditional desktop computers. [0003] However, due to the combination of liquid crystal volume and cell space, or when the coefficient of thermal expansion and contraction of liquid crystal is large, low-temperature liquid crystal bubbles are likely to occur once the temperature is low, especially when the liquid crystal panel is sold to high latitudes. or more pronounce...
