High-brightness touch screen capable of displaying clearly

Abstract

The invention relates to the technical field of touch screens, and particularly to a high-brightness touch screen capable of displaying clearly. The touch screen comprises a mounting frame, an inner cavity at the upper end of the mounting frame is set as a mounting inner cavity, a limiting rod is transversely welded at the lower end of the mounting frame, a bottom plate is fixedly welded to the lower end of an inner cavity of the mounting inner cavity, and a pair of sliding grooves in mutual symmetry are provided on the inner walls of the left and right sides of the mounting inner cavity,. Thetouch screen has the beneficial effects that grading type light supplementing lamps are arranged, so that light supplementing of different brightness levels is achieved, meanwhile, the light supplementing lamps are matched with reflection of the white board, direct light irradiation is avoided, light spots are prevented from appearing on the display screen, and the light supplementing effect is more uniform; and by arranging the electric rod capable of stretching up and down, up-and-down stretching installation of the touch screen is achieved, up-and-down lifting of the touch screen is achieved under strong illumination, the purpose of keeping out of the sun is achieved, the needed light supplementing intensity is reduced, and then the light supplementing cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch screen with high brightness and clear display. Background technique [0002] Touch screen, from the market concept, is a computer input device that everyone can use, or a device that everyone can use to communicate with computers. No need to learn, everyone can use it, which is the biggest magic power of the touch screen, which cannot be compared with the keyboard or mouse. Everyone can use it, which marks the real arrival of the era of popularization of computer applications. This is also the reason for developing touch screens, developing KIOSKs, developing KIOSK networks, and striving to form a Chinese touch industry. [0003] When the existing touch screen is installed, its light source is carried by itself. In a brighter environment, the light of the touch screen will appear weaker, so that it is impossible to recognize the specific position on the touch scre...

Problems solved by technology

[0003] When the existing touch screen is installed, its light source is carried by itself. In a brighter environment, the light of the touch screen will appear weaker, so that it is impossible to recognize the specific position on the touch screen. Some supplementary light devices are usually installed on the upper end of the touch screen, which is likely to interfere with the display of the touch screen
