Abstract

The invention discloses a detection device for the thickness of a liquid crystal panel. The detection device is characterized by comprising a light emitting system composed of a plurality of laser emitters and a laser controller, a light receiving system composed of laser sensors matched with the laser emitters in number, and a light processing device, wherein the laser emitters and the laser sensors are located above and below the liquid crystal panel. The light processing device and the light receiving system are connected in a communication mode. According to the detection device, online liquid crystal panel thickness measurement can be achieved, and the phenomenon that a panel with the abnormal thickness enters vacuum coating equipment, a photoresist coating machine and an exposure machine is avoided.

Description

technical field [0001] The invention relates to the detection field, in particular to a liquid crystal panel thickness detection device and an online detection method thereof. Background technique [0002] The touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various linking devices according to pre-programmed programs, which can be used to replace mechanical devices. The button panel of the style is adopted, and the vivid audio-visual effect is produced by the liquid crystal display screen. According to the classification of production process, touch screen can be divided into OnCell and InCell. OnCell refers to the method of embedding the touch screen between the color filter substrate and the polarizer of the display screen, that is, adding a touch sensor on the LCD panel, which is technically more difficult than...
