Projection capacitive screen is a screen that uses projection capacitive touch technology. The touch screen panel can detect changes in positional capacitance during finger touch, thereby calculating the position of the fingers and performing multi touch operations. 1) The surface glass and double-sided ito glass are both reinforced glass, and the surface layer is non-conductive glass. (2) The optical transparent adhesive between surface glass and double-sided ito glass is commonly used

Interactive electronic whiteboard is an electronic product. It consists of four parts, namely an induction board, an induction pen, a PC computer, and a projector. The sensing ratio can be used for writing and painting on interactive electronic whiteboards, and also has functions such as playback, recording, and teaching assistance. Interactive electronic whiteboards can be seen as a substitute for classroom blackboards. It is easy to use, environmentally friendly, and

Infrared touch screen

Infrared touch is the use of densely distributed infrared matrices in the X and Y directions to detect and locate user touch. The infrared touch screen is equipped with a circuit board border in front of the display screen, and the circuit board is equipped with infrared emission tubes and infrared reception tubes on all four sides of the screen, forming a horizontal and vertical infrared matrix.
