Abstract

The invention discloses a liquid crystal dripping device and a liquid crystal dripping method. The liquid crystal dripping device includes: a liquid crystal bottle for containing liquid crystal; a filter connected with the liquid crystal bottle and provided with a filter membrane; a pump connected with the filter, and the pump is used to pump the liquid crystal to the filter and pass through The filter membrane drips from the nozzle of the pump; the pressure sensor, located on the liquid crystal transmission channel from the filter to the nozzle, is used to detect the pressure value at the location to allow the pump to be controlled when the pressure value is greater than the preset pressure threshold stop running. Based on this, the present invention can be beneficial to timely and effectively monitor the clogging of the filter membrane of the filter, and control the pump to stop running when the clogging of the filter membrane is detected, thereby avoiding the damage of the filter membrane and the resulting foreign matter in the liquid crystal entering into the liquid crystal panel to cause Abnormal quality phenomenon.

Description

technical field [0001] The present invention relates to the field of liquid crystal display (Liquid Crystal Display, LCD) technology, and more specifically, relates to a liquid crystal dripping device and a liquid crystal dripping method. Background technique [0002] With the development of display technology, LCD and other display devices have been widely used in various consumer electronics products such as mobile phones, TVs, digital cameras, notebook computers, and desktop computers due to their advantages of high image quality, power saving, and wide application range. Become the mainstream of display devices. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module (Backlight Module). Wherein, the liquid crystal panel generally includes a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin FilmTransistor Array Substrate, T...
