Abstract

The invention provides a substrate heating device, comprising a furnace body, an intake pipeline and exhaust pipeline arranged on the furnace body, and a temperature control system communicated with the intake pipeline, with a substrate involved in the furnace body. The temperature control system is used for adjusting the temperature of gas entering the furnace body 1 from the intake pipeline. The substrate heating device provided herein comprises the temperature control system arranged on the furnace body and communicated with the intake pipeline; the temperature of gas entering the furnace body from the intake pipeline can be adjusted through the temperature control system; therefore, a temperature rise curve of the substrate is stable and controllable, baking effect is improved, and the problem of non-uniformity in film forming is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display processing, in particular to a substrate heating device. Background technique [0002] The alignment film is the key material to control the display quality of the LCD. In order to achieve a good rotation effect of the liquid crystal material, the alignment film (Alignment Layer) needs to be coated on the inner side of the upper and lower electrode substrates of the liquid crystal display, and then rubbed (Rubbing) process, the alignment film The surface will form grooves arranged in a certain direction due to friction, and the liquid crystal material on the alignment film will achieve an alignment effect due to the force between the molecules, resulting in an alignment effect, so that the liquid crystal molecules can be controlled according to a specific direction and predetermined alignment. inclination angle arrangement. Because resin (Polyimide, PI) has high light transmittance...
