Problems solved by technology

Because the glass itself is fragile and has poor impact resistance, it is difficult to deal with the light transmission of the back panel when used on LCD TVs.
At the same time, the glass cannot be punched, riveted, welded, etc.
The above difficulties limit the use of glass backplanes on LCD TVs

Embodiment 1

[0040] This embodiment discloses a glass backplane preparation process and the glass backplane. Such as figure 1 As shown, the glass backplane includes tempered glass 1, a first ink layer 2 is provided on one surface of the tempered glass 1, and a second ink layer 3 is provided on the side of the first ink layer 2 away from the tempered glass 1, and the second ink layer 3 An explosion-proof membrane 4 is provided on the side away from the first ink layer 2 . The first ink layer 2 and the second ink layer 3 increase the optical density of the glass backplane 1, which solves the problem of light transmission of the glass backplane; setting the explosion-proof film 4 increases the explosion-proof characteristics of the glass backplane and improves the safety of use . The preferred values ​​of the parameters of the glass backplane in this embodiment are as follows: the thickness of the tempered glass 1 is 3mm, the thickness of the first ink layer 2 is 0.01mm, the thickness of th...

Embodiment 2

[0056] This embodiment discloses a metal frame bonding process; the glass backplane used in this embodiment is the glass backplane in Embodiment 1. The area of ​​the first ink layer 1 on the glass back plate that is not screen-printed with the second ink layer 3 is the paste area, and the metal frame 5 (the material of the metal frame 5 in this embodiment is preferably aluminum) is pasted on the paste area. The metal frame 5 is bonded on the sticking area by acrylic AB structural glue, the sticking surface of the metal frame 5 is provided with a first groove 51, and the bottom surface of the first groove 51 is provided with a plurality of second grooves 52. In an example, three are preferred. The first groove 51 and the second groove 52 provided on the sticking surface of the metal frame 5 form a cavity with the sticking area, the glue will not flow out in the cavity, and at the same time, the overall sticking strength of the frame can be ensured. The second groove 52 can enh...

Abstract

The invention relates to the field of liquid crystal display technology, and discloses a glass backplane preparation process, a glass backplane and a metal frame lamination process; wherein, the glass backplane preparation process includes the following steps: S1, processing, the shape of the glass to be processed Carry out processing; S2, one-time silk screen printing, screen printing the first ink layer on one surface of the processed glass; S3, tempering and quenching, tempering the glass after one silk screen printing, and at the same time, the first ink layer of one silk screen printing Carry out quenching; S4, secondary screen printing, screen printing the second ink layer on the first ink layer after quenching; S5, set explosion-proof film, set a layer of explosion-proof on the second ink layer on the glass after the secondary silk screen printing membrane. Tempering and quenching treatment increase the surface stress and impact strength of the glass backplane, and improve the adhesion of the first ink layer; the first ink layer and the second ink layer increase the optical density of the glass backplane, solving the problem of glass backplane light transmission problem.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a glass backplane preparation process and a glass backplane and metal frame lamination process. Background technique [0002] With the popularization of LCD TVs and consumers' demand for high-quality TVs, the traditional metal backplane can no longer meet the needs of consumers. The glass backplane has the characteristics of good flatness, lightness, cleanliness, anti-glare, and good weather resistance, and the high value of the glass backplane gives people a high-end viewing experience. The use of glass backplanes on high-end LCD TV products will be a future a trend. [0003] At present, there are only a handful of manufacturers using glass backplanes for LCD TVs. Because the glass itself is fragile and has poor impact resistance, it is difficult to deal with the light transmission of the back panel when used on LCD TVs. At the same time, the glass cannot be st...
