Alignment film production device and production method

Abstract

A manufacturing apparatus and manufacturing method for an alignment film. The manufacturing apparatus comprises: a dropper (10) with multiple drip nozzles (101), an alignment layer (20) for allocating an alignment material for a substrate (30) on which the alignment material is dripped, wherein a grid (201) is arranged in an area of the alignment layer (20) corresponding to the area of the substrate (30) where the alignment material is dripped, so that the alignment material is dripped on the substrate (30) through the grid (201) on the alignment layer (20), and location deviation of the alignment material dripped on the substrate (30) which is caused by the location deviation of the drip nozzles (101) is avoided, thereby making a liquid crystal display component with a smaller frame. The manufacturing method comprises: controlling the moving of a drip nozzle (101) and a grid (201), and aligning a liquid crystal display component area (301) where an alignment material is dripped; the drip nozzle (101) dripping the alignment material on a corresponding grid (201) area where the alignment material is dripped according to a pre-set dripping track so as to fully distribute the alignment material on the surface of a substrate (30) and form an alignment material layer on the surface of the substrate (30); and curing the alignment material layer and using an alignment device to form multiple grooves in a pre-set direction and with a pre-set angle in the surface of the alignment material layer so as to facilitate the crystal to be arranged along the pre-set direction and angle and form an alignment film.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an alignment film manufacturing device and manufacturing method. Background technique [0002] With the development of the information society, people's demand for display devices has increased. In order to meet this demand, several types of flat panel display devices, such as liquid crystal display devices (LCD), plasma display devices (PDP), and OLED (organic light emitting diode) display devices, have been rapidly developed recently. Among flat panel display devices, liquid crystal display devices have basically replaced cold cathode display devices due to their advantages of low weight, small volume, and low energy consumption. [0003] Because the alignment film and liquid crystal are used in the production process of the LCD panel, and backlight is required at the same time, it becomes more difficult to make the frame of TFT-LCD (thin film transistor liquid crystal di...

AI Technical Summary

Problems solved by technology

[0004] The existing method of making an alignment film is: directly drop the alignment material onto the substrate through the drip nozzle, but in the process of this manufacturing method, due to the deviation of the driving motor, the position where the drip nozzle drops the alignment material to the substrate is deviated. , which in turn affects the frame of the liquid crystal display device
