82-inch multi-touch screen, 84-inch touch screen really 2:00, 4:00 true touchscreen

Infrared true multipoint technology Product Name: 8000 Series Infrared Touch Screen Product principle: infrared touch screen is used to detect and locate the user's touch use X, Y directions clouds on infrared matrix. Infrared touch screen frame to install a circuit board in the front of the display, a circuit board arranged in four sides of the screen infrared emission control and infrared receiver, infrared matrix correspond to the cross. When the user touches the screen, the finger will be blocked after the position of the infrared, which can determine the location of touch points in screen. Outside touch screen, is a highly integrated electronic circuits integrated product. Infrared touch screen contains a complete integrated control circuit, and a set of high-precision, interference infrared emission control infrared receiver and a set of cross installed in two opposite directions highly integrated circuit board, forming an invisible infrared grating. Embedded in the control circuit intelligent control system continuously formed on diode emits pulses of infrared beam grid bias shock. When you touch an object such as a finger into the grating, they block the light beam. Intelligent control system will detect a change in the loss of light, and transmits a signal to the control system to verify that the X-axis and Y-axis coordinate value. Touch screen parameters: resolution (interpolated) 4096 (W) * 4096 (D) scanning speed "120 frames / sec (mouse scanning speed 110 / second) linear error 1.4mm sensing objects with a finger, gloved hand or other non- the transparent touch-sensitive media to activate Touch Times Unlimited Touch Activation Force using infrared touch technology, without Touch Activation Force Minimum Touch Object 5mm touch mode is greater than a single point, multi-point, the mouse hot-swap applicable operating system Windows8 \ Windows7 \ Android \ Vista \ XP \ 2003 \ 2000 \ CE, Linux, MacOS (driver-free, plug and play) Response time 10ms detection software supporting touch screen detection software, an intuitive touch-screen response waveform interfaces all the way to the tube USB / EIA-232E power supply USB bus or PS / 2 interface power supply operating voltage typ + 5VDC, permissible range + 4.75V ~ + 5.25V operating power <3W, working current <400mA environmental parameters: temperature should be -20 ℃ ~ 70 ℃ storage temperature should be -40 ℃ ~ 80 ℃ Operating Humidity 90% RH at 40 ℃ non-condensing Storage humidity 90% RH non-condensing at 40 ℃ glass characteristic: the violence of the mass of 1.5kg smooth surface of the ball, height of 1 meter free fall, glass No damage. Surface Durability broken glass surface hardness equal, Mohs' hardness rating of 7 transmittance ≥95%, up to 100% (no glass) Main Features: 1. Using self-developed touch technology, ARM processing controller, response speed fast; 2. imported LED die, long life; 3. redundant processing technology, individual LED bulb does not work does not affect the results; 4 via USB connection, without having to install drivers, plug and play; 5 can be built in a variety of one machine, then the product range, ease of integration; 6. posted outside the high hardness glass, uprising and strong, no scattering, no drift; 7 touch screen borders narrow thin thickness; touch technology for low system requirements , the fastest response only 8ms, there is no sense of delay; advanced touch algorithm, the lowest power rating of less than half the robust fault tolerance, even if the wrong point does not affect use; bilateral beam core algorithm, fear shelter, misuse .
