Ultrathin backlight module and touch all-in-one machine based on ultrathin backlight module

Abstract

The present invention relates to an ultrathin backlight module and a touch all-in-one machine based on the ultrathin backlight module. The ultrathin backlight module comprises a support assembly, wherein the support assembly comprises a frame body and a backboard cooperated with the frame body, and an accommodating space is formed between the frame body and the backboard; a light guide plate assembly, wherein the light guide plate assembly is installed in the accommodating space, and the light guide plate assembly comprises a reflecting layer, a light guide plate and an optical film which are successively laminated, and a light source corresponding to an in-light surface of the light guide plate; and a liquid crystal assembly, wherein the liquid crystal assembly is disposed in the accommodating space, and the liquid crystal assembly comprises a liquid crystal screen installed between the frame body and the optical film and a PCB connected with the liquid crystal screen. By adoption of the specific support assembly, the light guide plate assembly and the liquid crystal assembly for cooperation, so that the number of used materials and equipment is obviously reduced, the thicknesses can be reduced when cost is reduced, and therefore the thicknesses of the light guide plate assembly and the liquid crystal assembly are reduced to about 6mm. Ultrathin design of the touch all-in-one machine is finally achieved, and the thickness of the touch all-in-one machine can be reduced to about 25mm.

Description

technical field [0001] The invention belongs to the field of display devices and relates to a touch integrated machine, in particular to an ultra-thin backlight module and a touch integrated machine based on it. Background technique [0002] figure 1 It is a structural schematic diagram of an existing touch all-in-one machine, which includes the all-in-one machine body 1' and the plastic back shell 2' installed on the all-in-one machine body 1' to play a fixed role, which undoubtedly increases the thickness of the product. The development trend of ultra-thin touch all-in-one machines does not match. More importantly, the existing all-in-one machine body 1' such as figure 2 As shown, it includes a backlight module 11', a liquid crystal component 12' and a touch component 13'. The backlight module 11' is a conventional structure, which includes a reflective sheet 111', a light guide plate 112' and an optical film 113' stacked in sequence, a light source 115' arranged on th...

AI Technical Summary

Problems solved by technology

It can be seen that the existing touch all-in-one machine has a complex structure, and there are many types and quantities of components, which need to be installed and fixed by means of tapes, screws and other components; The thickness of the touch all-in-one machine is about 20mm, and the thickness of the whole touch all-in-one machine is as high as 50mm, resulting in heavy product weight, thick product thickness, high cost, wide frame and complex module structure, making it difficult to design a beautiful appearance and low cost. cost-effective all-in-one solution
