Problems solved by technology

[0005] 1. Apply glue to bond the backlight box and the plastic panel, the production time is a little longer, and it cannot be disassembled for maintenance;
[0006] 2. Paste with thicker double-sided tape, and there will be up and down, left and right shaking;
[0007] 2. Connect the backlight box with the plastic panel directly by screwing, the Mura is serious and the pass rate is low;
[0008] 3. To separate the backlight box, too many parts are assembled in a high-level clean room, especially the plastic panel meets the clean level of the workshop, and the cost is very high

Abstract

The invention discloses a fixing device of a display screen backlight module. The fixing device comprises a display screen module provided with a backlight box, a backlight support, a panel and a screw, wherein the backlight support is bonded with the backlight box, the display screen module is fixedly connected with the panel, a screw hole is formed in the back of the backlight support, a stud longitudinally extends from the screw hole and is at least cut into two pieces, and a hole position matched with the stud is arranged at the back of the panel. During use, the stud is nested in the holeposition and the screw is screwed into the stud. By means of the technical scheme, the problem of Mura display caused by tolerance accumulation is effectively reduced.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a method and device for fixing a display backlight module. Background technique [0002] At present, vehicle-mounted touch screens are required to be manufactured using a full lamination process. Full lamination is a production process in which the display module and the touch screen are completely and tightly bonded together through optical glue without an air layer in between. Compared with the previous frame bonding, the advantage of the full bonding process is that it can achieve the display screen: one-piece black (the color of the VA area is similar to that of the non-VA area); low reflectivity (good anti-glare effect, unclear reflection), high-definition (display screen Clear), the thickness is thinner. Fully laminated modules require the entire package to be completed in a high-level clean room, and then to a low-level clean room to complete the process of pasting with the...
