Touch Screen

Touch Screen allows users to just use your fingers gently touch the computer screen or text on the icons on the host OS can be achieved, so get rid of the keyboard and mouse, make computer interaction more straightforward. Hall is mainly used in public places, information inquiry, leadership office, video games, song a la carte, multimedia, tickets / ticket pre-sale and so on. Products are mainly divided into capacitive touch screen, resistive touch screen and three types of surface acoustic wave touch screen.Touch-screen display categoriesDepending on the touch screen and works with the media, can be divided into resistive, capacitive, infrared-and surface acoustic wave, optical and other.Edit this paragraph touchscreen display technologyTouch-screen display technology is a new interactive input mode, with the traditional keyboard and mouse input as compared to touch screen input is moreAnd intuitive. Beijing Heng Yuan Technology Development Co., Ltd. Techtronic market to meet customer needs, has developed a multi-touch screen display, with the recognition software, touch screen handwriting input can be achieved. Touch screen monitor installed in the front of the screen and touch screen controller detection component parts. When fingers or other objects touch display installed in front of the touch screen, the touch position detected by the touch screen controller, and through the interface (such as RS-232 serial port) to the host.Large touch screen functionMultifunctional smart board and computers, projectors together to form a large touch screen, the computer screen through the projector projected onto the smart board to replace the mouse pointer or finger operation in the smart-board computer, control and application software, Windows or Macintosh.Surface acoustic wave touch screenSurface acoustic wave touch screen touch screen part of the glass is a transparent, it can be made flat, cylindrical or spherical, and the surface of the touch screen does not need to add a special coating. This kind of touch screen on the corner with the ultrasonic transducer can transmit a high frequency sound waves across the screen surface. When a finger or other be able to absorb or block sound energy of an object touching the screen, parts of the acoustic energy through the fingers are partially absorbed, according to the coordinates of the receiver can determine the location of the signal changes. The same compared to other types of touch screen, surface acoustic wave touch screen independent of temperature, humidity and other environmental factors, high resolution; transmittance is good, can maintain a clear bright image quality; reaction speed; a third axis (ie pressure axis ) response, so widely.
