Compared with the traditional electronic screen, LED splicing smart board interactive whiteboard screen can be used as a single separately, also can joining together into a super big use. According to the different needs of users, can realize the function becomes a big small. Splicing screen also supports the digital zoom and stretch, across the screen display, full hd signal real-time processing.
Multi-touch screen using infrared touch screen, the use of infrared matrix of distribution in the X, Y direction, to detect and locate the user's touch. Infrared touch screen installed in front of the display circuit board frame, smart interactive whiteboard circuit board on the four sides of the screen set with infrared transmitting tube and infrared receiving tube respectively, they somehow the infrared way matrix corresponding to each other. When users touch screen, fingers will block through the location of horizontal and vertical two infrared electronic whiteboard line, which can determine the location of the touch point on the screen. Infrared touch screen is a kind of highly integrated electronic integrated circuit products. Infrared touch screen contains the complete integrated control circuit, and a set of high accuracy and anti-interference of infrared transmitting tube and a set of infrared receiving tube, two smart board whiteboard opposite direction is installed in a highly integrated circuit boards, forming an invisible infrared grating. Embedded in the control circuit intelligent control system of continuous pulse diode to form infrared polarization beam grid. When a finger touching objects into the grating, it will block the beam. Intelligent control system will detect the change of the light loss and sends a signal to the control system to ensure that the X axis and Y axis coordinate values.
Multi-functional development trend of intelligent touch-screen interactive digital whiteboard machine is accord with the demand of the market, meet the use of effective resources to achieve a variety of functions.
LCD advertising machine more and more commercial scene, common means used to broadcast push merchants set up good advertising video program, etc. Although television can also be used to broadcast advertising video program, but often it is through the USB interface, that is to say, U disk, mobile storage devices, to play, but LCD advertising machine, can real-time network synchronization dozens of units, hundreds of LCD advertising machine electronic board for classroom of the video content. Due to the merchant's business hours are usually relatively long, all don't have to consider the power consumption, can be equipped with higher brightness of LCD display, such as: nita, 500, 700 nita, outdoor LCD advertising machine can even reach 2000 nits brightness. Could use some friends for touch screen machine, is a fresh thing. Larger feature that is with the function of touch, people can interact with the screen.
Common scenarios such as: teaching whiteboard, meeting PPT presentation, etc. Usually PC touch screen machine, X86, WINDOWS architecture will be more common, that is to say, is also a computer touch screen machine, touch screen machine also have the relevant interface and function of the TV set. Can do to when to use the TV set. So some friends, will call for touch TV and touch screen machine touch TV, that is the reason.
