Embodiment Construction

[0033] In order to understand the purpose, features and advantages of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] See Figure 2a ~ 2g It is a structural schematic diagram of an embodiment of the present invention.

[0035] Such as Figure 2a As shown: a PI alignment film 21 (which may be polypropylene resin or polyimide resin) is printed on the surface of the TFT array substrate 20 to form an alignment film for controlling the alignment of liquid crystal molecules.

[0036] Such as Figure 2b As shown: a thickness-controlled frame glue wall 22 (which can be heat-curable epoxy resin or ultraviolet-curable epoxy resin) is coated at a certain height on the periphery of the array substrate 20 where the alignment film is formed. The scattered spacers are used to control the thickness of the liquid crystal layer (not shown), so that a uniform gap is formed between...

Abstract

The invention relates to a LCD-making method, especially a LCD-making method of packaging and making liquid crystal material by using the double-layer structure where the liquid layer is covered with polymer film and which is formed in the course that the polymer monomer is separated with the liquid crystal in the polymerization reaction during the no liquid crystal injection course of a single-basal plate. According to the requirement for device structure, it further uses the techniques of coating, splashing, photoetching, etc to complete making the liquid crystal screen. Compared with traditional liquid crystal screen making techniques, it omits the courses of making an empty box and injecting liquid crystal into the empty box. It has obvious advantage in making plastic basal boards and large-sized LCD. It can also use plastic basal plate, thus making the made liquid crystal screen very thin, and further reducing the thickness and weight of the liquid crystal screen box.

Description

technical field [0001] The invention relates to a liquid crystal display manufacturing method of a liquid crystal display. In particular, it relates to a single-substrate-free liquid crystal injection process, using the phase separation process of polymer monomers and liquid crystals in the polymerization reaction to form a double-layer structure in which the liquid crystal layer is covered by a polymer film to realize the encapsulation of liquid crystal materials. Manufacturing method of LCD screen. Background technique [0002] Liquid crystal displays have developed rapidly due to their thinness and low power consumption, and have been widely used in various information display devices in recent years. The market's demand for large-area, thinner and lighter liquid crystal displays is also becoming stronger and stronger. [0003] The existing thin film transistor liquid crystal display uses the injection method at the stage of manufacturing the liquid crystal box, and the...
