LED touch panel, also known as touch screen or touch panel, is an inductive LCD or thin screen display LED touch panel device that uses a light source to receive input signals from contacts, including fingers and special rubber pens. When the graphic button on the LED touch pane is touched, the tactile feedback system of the LED touch panel can drive various connection devices according to the pre-programmed program. The LED touch panel can be used to replace the mechanical button panel, and the display screen can produce vivid film and television effects. As a new PC input device, the LED touch panel is currently the simplest and most convenient way of human-computer interaction.
Composition of optical touch panel components
The components of the optical touch panel include glass substrate, infrared emission source, infrared receiver, etc. The optical touch panel structure mainly places the infrared emission device on the left and lower side of the glass panel, and sets the infrared receiver on the right and upper side of the optical touch panel. When the finger or rubber pen blocks the infrared, the information received by the receiver of the optical touch panel can measure the location of the contact point. The advantage of optical touch panel is that its surface is pure glass, which will not affect the transmittance, and optical touch panel has high reliability, scratch resistance, and fire resistance, but optical touch panel also has disadvantages that it is poor in water resistance and antifouling.
led touch screen panel
led touch screen panels are composed of many small-sized LED arrays. The led touch screen panel has the advantages of high brightness, high contrast, high resolution and high color saturation. The metal grid material used in the led touch screen panel is low in price and cost. And the led touch screen panel made of metal grid material can improve the transmittance of the touch screen panel and enhance the visual effect.
What is touch panel USB
touch panel USB is an external bus used for connection and communication between PC and external devices. Touch panel USB is an interface technology used in the PC field. The touch panel USB uses a four-wire cable, two of which are serial channels for transmitting data. The other two of the touch panel USB provide power to downstream devices, and for peripherals that have been successfully connected and recognized by each other. Data will be transmitted at the highest rate that both devices can support. The touch screen panel USB bus will automatically match the high and low dynamic conversion and lock the appropriate rate in the compatible transmission mode according to the peripheral situation. For other matters about the led touch panel, please contact the touch panel manufacturer.
