The principle of optical touch screen Introduction and Market Analysis oled module

I. Overview:
Simple, accurate and fast response. CCD optical touch technology to break the bottleneck of the original touch technology, accuracy, speed of response and life has greatly improved. Installed at the top left and right corners of the two CCD camera can accurately detect multiple fingers of your position, you can not only click, drag, and also free to rotate and zoom the picture, these operations depends on the quantity and unit of your finger area. You can also gently touch the screen, enjoy the control of three-dimensional movement of objects and fun screen virtual animals up close.lcd module manufacturer 

CCD optical touch system
Installed in the top left corner of the CCD camera, the light emitted by the LED lamp, reflector after four weeks reflective strips, into the upper right corner of the CCD camera. Similarly, the incoming light emitted by the CCD camera of the upper right corner of the left side of the CCD camera. clouds of light forming a light touch area network, through the space between the multiple reflections of light is less than 1MM. When the touch point, the point of the emitted light and receiving light to form an angle, and both ends of the CCD camera is composed of two angle with the straight line formed between two light and two cameras will, so that the accuracy of the point coordinate controller input, the touch response. The principle is that when the multi-touch!Lcd display module
