Abstract

The invention discloses a manufacturing device of a display panel and a cleaning method for the manufacturing device of the display panel. The manufacturing device of the display panel includes: a machine table for carrying and transmitting a glass substrate; a working pipe, arranged above the machine table, and used for conveying a material to act on the glass substrate; a gas supply device in communication with the working pipe through a gas supply pipeline; a liquid supply device, in communication with the working pipe through a liquid supply pipeline, wherein a detection device for detecting a state of the glass substrate on the machine table is arranged on the machine table, a first automatic valve is arranged on the gas supply pipeline, and a second automatic valve is arranged on theliquid supply pipeline to wash the machine table and the working pipe, thus crystallization velocity at an exit of the working pipe is reduced or crystallization at the exit of the working pipe is eliminated, light resistance loss of the glass substrate is reduced, stability of manufacture procedures of the display panel is improved eventually and production cost of the display panel is lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a manufacturing device and a cleaning method for a display panel. Background technique [0002] With the development and progress of science and technology, liquid crystal displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. 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. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occup...
