Abstract
An improved infrared touching-type white-board liquid crystal displayer which comprises a liquid crystal display screen, a liquid crystal display control unit, an infrared touch panel and a touch action recognition unit, and is characterized in that the displayer also comprises a computer system, the infrared touch panel is connected with the touch action recognition unit, an output end of the touch action recognition unit is connected with the computer system, an output end of the computer system is connected with the liquid crystal display control unit, and an output end of the liquid crystal display control unit is connected with the liquid crystal display screen. According to the improved infrared touching-type white-board liquid crystal displayer, the problem of being single in function of the prior art is solved.
Description
Technical field
The utility model relates to a kind of improved infrared touch type blank liquid crystal display, and it belongs to the display class.
Background technology
Powerful interactive teaching and the demo functions such as electronic whiteboard can realize writing, wipe, marking that (literal or lines mark, size and angular dimension), drawing, object editing, form are preserved, dragged at display screen, amplification, draw curtain, spotlight, screen capture, picture preservation, film recording and playback, handwriting recognition, keyboard input, text input, video-audio make people rely on no longer merely traditional blackboard and chalk.Along with the development of electronic technology, electronic whiteboard is the best solution of information age office, teaching, picture and text interactive demonstration, now is widely used in the industries such as commercial enterprise, education ﹠ training industry, government bodies, TV media, display and demonstration.In the prior art, electronic whiteboard generally comprises display screen, touch screen and blank control device, and described blank control device mostly is embedded system, in order to the demonstration of the touch-control behavior of identifying people and control display screen.The problem that prior art exists is that the electronic whiteboard function of such version is comparatively single, can only substitute simply traditional blackboard, can not satisfy the needs of teaching today, exhibition and Information Communication, and obviously prior art has further improved necessity.
Summary of the invention
The purpose of this utility model is to provide a kind of improved infrared touch type blank liquid crystal display, the problem that exists to overcome prior art.
A kind of improved infrared touch type blank liquid crystal display of the present utility model, comprise LCDs, liquid crystal display control module, infrared touch screen and touch-control behavior recognition unit, characterized by further comprising a computer system, described infrared touch screen is connected with touch-control behavior recognition unit, the output terminal of described touch-control behavior recognition unit is connected to computer system, the output of described computer system is connected to the liquid crystal display control module, and the output of described liquid crystal display control module is connected to LCDs.
This improved infrared touch type blank liquid crystal display of the present utility model, except the function with traditional liquid crystal indicator, the function that also possesses electronic whiteboard, the two combination, the alternative traditional blackboard of one side, can also very well carry out multimedia display on the other hand, obviously the problem of prior art existence is solved.
As preferably, the output terminal of described touch-control behavior recognition unit is connected to computer system by the RS232 interface, and is simple in structure like this.
