Embodiment 1

[0040] Step A, laminating the OCA optical glue 2 (thickness more than 175 μm) on the lower surface of the strengthened glass cover plate 1;

[0041] Step B, the glass cover plate 1 and the azimuthal bistable nematic liquid crystal display 3 are vacuum laminated by a hard-to-hard laminator;

[0042] Step C, subjecting the liquid crystal display 3 laminated with the glass cover plate 1 to UV irradiation treatment and high-pressure defoaming treatment;

[0043] Step D, when the PC plastic frame 4 is injected, the installation part 5 is formed by recessing, and the sealing hot melt adhesive 6 is applied around the PC plastic frame 4 with a dispenser;

[0044] Step E, the liquid crystal display 3 treated in step C is attached to the installation part 5 of the PC plastic frame 4 with a jig, and is kept under pressure and cured for 1 hour;

[0045] Step F, test the airtightness of the device, and the qualified products can be shipped.

Embodiment 2

[0047] Step A, the strengthened glass cover plate 1 and the liquid crystal display 3 are pasted together by LOCA 2 (liquid optical glue or water glue);

[0048] Step B. Position the glass cover 1 and the azimuthal bistable nematic liquid crystal display 3 respectively on the water-glue laminating machine, first apply LOCA 2 on the glass cover 1, and the two are automatically bonded in the machine (LOCA The bonding thickness is generally controlled at 250μm to 500μm.);

[0049] Step C, after heating and leveling, UV radiation curing is performed on the exposed side of the glass cover plate 1, and then UV radiation side curing is performed on the surrounding side, followed by high-pressure defoaming treatment.

[0050] Step D, when the PC plastic frame 4 is injected, the installation part 5 is formed by recessing, and the sealing hot melt adhesive 6 is applied around the PC plastic frame 4 with a dispenser;

[0051] Step E, the liquid crystal display 3 treated in step C is atta...

Abstract

The invention relates to an azimuth bistable liquid crystal display electronic license plate module and a manufacturing method thereof. The azimuth bistable liquid crystal display electronic license plate module comprises a transparent protective cover, an optical adhesive layer, an azimuth bistable nematic liquid crystal display and a fixing frame, wherein the transparent protective cover is arranged on one side of the azimuth bistable nematic liquid crystal display in a fitting manner through the optical adhesive layer, one side of the fixing frame is recessed to form a mounting part, and the side, away from the transparent protective cover, of the azimuth bistable nematic liquid crystal display is arranged in the mounting part in a fitting manner. The azimuth bistable liquid crystal display electronic license plate module has the advantages that black and white display of the electronic license plate module can be realized based on the azimuth bistable nematic liquid crystal displaytechnology, the module has a high contrast, a wide viewing angle and good visibility under sunlight, no power is consumed basically when display information is maintained, and power is needed only when display content is refreshed.

Description

technical field [0001] The invention relates to the technical field of an electronic license plate of a liquid crystal display, in particular to a module of an electronic license plate of an azimuth bistable liquid crystal display and a manufacturing method thereof. Background technique [0002] At present, traditional car licenses at home and abroad will still occupy the dominant position in the market of stock cars and new cars in a certain period of time in the future. However, with the development of social life, the Internet of Everything and intelligence are the inevitable development trends of all means of transportation, including cars. Governments of various countries In order to implement more efficient social management methods, we are also trying to introduce various digital identification schemes for automobiles. For example, the RFID electronic identification of automobiles that is being implemented in my country will integrate vehicle identification, micropaymen...
