Problems solved by technology

As the size of the screen increases, the thickness of the protective glass becomes thicker. Since the protective glass of the LCD panel and the material of the LCD panel are made of glass, and the glass will warp during production and processing, the larger the size of the screen made of glass The greater the warpage (the 84-inch LCD panel is affected by the warpage and its own gravity, the warpage caused by the front arch and the rear warp is as high as 5-8mm), and the protection glass of the LCD panel is easily pressed by hand. The radioactive Newton's halo will be generated after touching the LCD panel, and the contact between the LCD panel and the light guide film of the backlight module will cause uneven brightness at the contact and non-contact areas. The size of the panel is increased and the height is increased, which in turn causes a larger air gap. The light loss caused by the gap reduces the clarity of the image, and the larger the gap is, the greater the light loss of the backlight source is. Due to the wide viewing angle of the panel, the condensation of moisture in the gap will make the back of the LCD panel and the surface of the backlight module foggy and moldy
On the other hand, the plastic clamping structure of the liquid crystal panel is also likely to cause uneven light refraction and light distortion on the clamped and unclamped panels, resulting in point-like light leakage from the backlight.
Although the LCD panel with a thickness of only 1mm is clamped in the plastic frame, it is still very fragile, especially the 86-inch LCD panel with an area of ​​more than 2 square meters is only 0.8mm thick, and it is very easy to break during transportation

Abstract

The invention discloses an infrared touch control liquid crystal integrated screen display module. An infrared frame of the infrared touch control module comprises a touch control sensing element mounting part and an infrared frame extension part extending downwards along the outer side of the touch control sensing element mounting part; liquid crystal panel protective glass is stuck to the front surface of a liquid crystal panel to form a liquid crystal panel integrated screen; the touch control sensing element mounting part is stuck to the periphery of the front surface of the liquid crystal panel protective glass of the liquid crystal panel integrated screen; the liquid crystal panel of the liquid crystal panel integrated screen is not in contact with the infrared frame of the infrared touch control module; an infrared touch control sensing element is mounted in the touch control sensing element mounting part; a direct type backlight module is located on the back surface of the liquid crystal panel integrated screen; every two adjacent films and every two adjacent plates of the direct type backlight module are stuck to the periphery to form an optical film integrated layer, and the optical film integrated layer is stuck to the edge of an opening part of a back plate; no other supporting part is arranged between the direct type backlight module and the liquid crystal panel; the back plate of the direct type backlight module is buckled with the infrared frame extension part.

Description

technical field [0001] The invention relates to the field of multimedia equipment, in particular to an infrared touch liquid crystal integrated screen display module. Background technique [0002] With the rapid development of the intelligent network world, the touch screen has become a window to display network information in all directions. Among them, the infrared LCD screen is widely used in the education system and face-to-face shopping because of its low cost, accurate positioning, high precision and fast response. System, face-to-face logistics system and other fields have been widely used. [0003] The structure of traditional infrared touch liquid crystal display includes display front shell, infrared frame, liquid crystal panel protective glass, liquid crystal panel, direct-lit backlight module and display rear shell. The touch sensing element, the protective glass of the liquid crystal panel is embedded in the infrared frame from the back and is clamped by the po...
