Description

Manufacturing method of liquid crystal display

technical field

The present invention relates to a liquid crystal display device and its manufacturing method, in particular to a manufacturing method of a single-layer color cholesteric liquid crystal display device.

Background technique

Liquid crystal displays (LCDs) have many advantages, such as small size, light weight, low power consumption, and so on. Therefore, LCDs have been widely used in electronic products such as portable computers and mobile phones. That is, the liquid crystal display technology is continuously developing towards the field of being light, thin and easy to carry. The traditional reflective colored liquid crystal display with memory effect has been widely used in electronic books, electronic paper or other display fields. The structure and manufacturing method of the traditional color cholesteric liquid crystal display uses red (R), green (G), blue (B) three-layer liquid crystal stack structure, with a variety of different driving methods. However, the red, green, and blue liquid crystal stack structure causes parallax phenomenon, which may cause difficulty in alignment of the panel structure during manufacture, increase the difficulty of electrode design and inability to bend and be inconvenient to carry, resulting in complicated process and high manufacturing cost.

On the other hand, the display manufactured by the roll-to-roll process technology has the characteristics of fast production speed, low cost, and thinness, and can be widely used in electronic books, electronic paper or other display fields. Traditional color liquid crystal displays use multi-channel photolithography patterning process, although complex patterns and structures can be produced, but the complex process makes it difficult to reduce the cost.

The traditional tape-and-roll process technology is used to manufacture flexible substrate displays, focusing on a single process function, and there are also panels that integrate the roll-to-roll process. U.S. Patent No. 4,973,373 discloses a method for fabricating a display by roll-to-roll. Utilize the design of the roller to control the tension, deformation and displacement of the flexible board in the roll-to-roll process, and integrate the patterning function to achieve the production of the display. However, as far as the passive memory single-layer color display is concerned, it does not need such a complicated system to achieve the characteristics of roll-to-roll production.

U.S. Patent No. 5,943,113 discloses a process that integrates tape-and-roll liquid crystal coating, adhesive material coating, frame glue coating, and upper and lower plate lamination. The liquid crystal coating process and patterning process cannot be perfected, and the display structure is also different from the passive memory single-layer color display structure.

US Patent No. 7,081,180 discloses a method for manufacturing a passively driven liquid crystal display. Integrating transparent conductive pattern coating, liquid crystal coating and cutting, the panel structure is simple and does not conform to the current panel structure design.

FIG. 1 shows a schematic diagram of a conventional passively driven liquid crystal display manufacturing method. Please refer to FIG. 1 , the manufacturing method of the conventional tape-and-roll type passively driven liquid crystal display includes forming a lower substrate 60 containing electrode patterns by using a tape-and-roll coating machine, and conveying it to an adhesive material coating device 80 via a substrate conveying roller 50, and coating Adhesive material81. On the other hand, the roll-type upper substrate 70 containing electrode patterns is provided, and the lower substrate 60 is laminated into a substrate structure by the substrate rolling bonding device 51 at the same time, and then successively sent to the structure curing device 90, and the cutting device 20 is used to form the non-perfusion Liquid crystal panel structure unit 21. Then, a subsequent liquid crystal perfusion step and other subsequent processes are performed.
