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

Embodiment Construction
[0029] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] like figure 1 and figure 2 as shown, figure 1 It is a specific structural diagram of the first embodiment of the alignment film manufacturing device of the present invention, figure 2 A specific structural diagram of the second embodiment of the alignment film manufacturing apparatus of the present invention.
[0031] The alignment film manufacturing device includes: a dripper 10 with a plurality of drip nozzles 101, and an alignment layer 20 for distributing alignment materials to a substrate 30 of the alignment material to be dropped, wherein the alignment layer 20 is aligned with the substrate 30 to be dropped. The corresponding area of the material area is provided with a grid 201 , and the grid 201 allows the alignment material dropped from the drip nozzle 101 to pass through and drop toward the are...

The invention discloses an alignment film manufacturing method which includes that moving of a drip nozzle and a grid is controlled, and a liquid crystal display device area where an alignment material is dripped is aligned; the drip nozzle drips the alignment material on a corresponding grid area where the alignment material is dripped according to a preset dripping track, the alignment material is fully distributed on the surface of a substrate, and an alignment material layer is formed on the surface of the substrate; the alignment material layer is cured, a plurality of grooves in the preset direction and with a preset angle are formed in the surface of the alignment material layer through an alignment device so as to be favorable for liquid crystal to be arranged along the preset direction and angle, and an alignment film is formed. By arranging an alignment layer above the substrate and by arranging the grid in an area of the alignment layer corresponding to the area of the substrate where the alignment material is dripped, the alignment material is dripped on the substrate through the grid on the alignment layer, position deviation of the alignment material on the substrate caused by deviation of a drip nozzle position is avoided, and a liquid crystal display device with a smaller frame is manufactured. The invention further provides an alignment film manufacturing device.
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...
