Description
Technical field
Multimedia equipment field is the utility model is related to, more particularly to a kind of infrared touch liquid crystal integrally shields display module.
Background technology
With the rapid development in the intelligent network world, touch display screen oneself become the window of the display network information from all directions
Mouthful, wherein infra-red liquid crystal screen because its low cost, accurate positioning, precision is higher, reaction speed is very fast the advantages of in educational system, face
It is used widely depending on purchase system, face depending on fields such as logistics systems.
Traditional infrared touch liquid crystal display structure includes display front-housing, infrared frame, liquid crystal panel protective glass, liquid
Crystal panel, down straight aphototropism mode set and display rear shell, the infrared seal ring thickness and width are more than 40mm, infrared side
Frame top is embedded with infrared touch sensor, and liquid crystal panel protective glass is embedded in infrared frame and with positioning strip card from behind
Tightly, the liquid crystal panel is clamped by a square shape plastic frame, and the plastic frame periphery for clamping liquid crystal panel is provided with for solid
Determine the positional punch of optical diaphragm, set screw passes through the through hole on plastic frame periphery and is locked in down straight aphototropism mode set week
In the positional punch on side, liquid crystal display die set is formed so that liquid crystal panel is fixed on backlight module face, then by display
Front housing and display rear shell, liquid crystal display die set and infrared frame are fixed together.
Traditional infrared touch liquid crystal display structure is not only thick and heavy, and clamps on the plastic frame both sides of liquid crystal panel all
There is cushion pad, plastic frame surrounding is provided with to limit the boss of liquid crystal panel transverse shifting, and use is provided with the boss
In the positioning press strip that vertically moves of limitation liquid crystal panel, wherein, the plastics clamp frame and its cushion pad formed liquid crystal panel with
Gap between backlight module, boss, positioning press strip and its cushion pad formed again liquid crystal panel and liquid crystal panel protective glass it
Between gap.With the increase of screen size, the thickness of protective glass is also thicker, due to liquid crystal panel protective glass and liquid crystal surface
