Background
The existing box support of an information display screen such as a liquid crystal display screen comprises a frame support and a box inner support, wherein the frame is generally formed by hardening SPAER by epoxy resin glue, the support is strong, the supported area is generally not easy to deform, the box inner support is generally formed by a plastic ball spacer, smaller spraying density (70-150 pieces/mm 2) is needed, and certain elastic deformation is needed to ensure uniform and consistent transmittance and box thickness, so that the support force is relatively weak. For large-size liquid, as the middle area is far away from the strong supporting area of the edge pattern, a touch screen structure is additionally arranged or a cover plate attaching processing mode is adopted, or in practical application, the liquid crystal screen can be influenced by external force such as vibration and extrusion, so that the deformation of the liquid crystal box is easily caused, further the problems of uneven appearance of black and white spots, shaking of display pixels and the like are caused, and the thickness of the box can be changed.
In order to solve the problems of black and white spots, display pixel shaking or box thickness change and the like caused by external force influence on a large-size liquid crystal screen, stronger and more stable support needs to be carried out on relevant areas in a box, the prior art has the common practice that if the density of a spacer is increased, for example, the powder spraying density exceeds 300 pieces/mm 2, so as to enhance the supporting force, but the local strong support cannot be realized in the mode, the spacer can only be sprayed in a full screen mode, more negative problems are brought about in the mode, for example, appearance white fog brought by the movement of the spacer, and the light transmittance of the display area is seriously influenced by spaer; yet another solution is to use existing technology to locally support strongly, similar to the printing of the border (epoxy + hard powder) into the box to strengthen the support, but because the border material is epoxy, the optical properties are very different from other layers in the box, with the negative problem that these support areas can be seen by the human eye when reflecting light, and the whole screen cannot achieve uniform and uniform integral black.
