The 23.6 inch touch screen panel with usb interface uses industrial touch chip ILI2510, which has strong anti-interference performance and can be used in a variety of complex application environments. Such as work well with 3-10mm thickness tempered glass, gloves.
The G+G 23.6 inch touch screen panel with usb interface is a capacitive multi-touch screen that can handle 10 touch points simultaneously. This provides extremely accurate operation supporting many different gestures, including swiping, zooming and more.
Interface Type:USB ( plug and play)
Controller IC : ILI2510
Touch Points:1-10 Points
Power Supply Voltage:5V
1.Support Touch with glove of all materials and thickness with 6mm
2.Support Touch with water/brine
3.Cover glass Support -8mm thickness--explosion-proof
4.Cover glass surface treatment--AG, AR, AF
Anti Glare (AG) processing could eliminate screen surface mirror problem through converting direct light to diffuse light on the touch screen.
AR processing means adding a type of coating that could reduce reflected light on the cover glass,which dereases screen reflection and increases visual effects significantly in the sun.
AF processing is adding on the cover glass a king of coating that could increases surface smoothness, reduces surface sliding resistance , residual water and fingerprints on the surface significantly and improves feeling and clarity.
Technical Q & A
Q: What is the principle of capacitive touch screen to achieve multi-touch?
A: When the finger touches the capacitive screen, it affects the coupling between the two electrodes near the touch point, thus changing the capacitance between the two electrodes. When detecting the mutual capacitance, the lateral electrodes sequentially emit excitation pulse signals, and all the longitudinal electrodes receive signals at the same time, so that the capacitance values of all the intersections of the lateral and longitudinal electrodes can be obtained, that is, the capacitance of the two-dimensional plane of the entire touch screen. According to the two-dimensional capacitance change data of the touch screen, the coordinates of each touch point can be calculated. That is, the real multi-point coordinates can be calculated to realize multi-touch;
Q: If the display screen and the capacitive touch screen are designed to be assembled separately, what attention should be paid?
A: If the installation is separate for display and touch, the main factor should be considered is the gap between the capacitive touch screen and the display. it is better to control it within gap between 0.5 to 2mm because if it is less than 0. 5mm when the display screen is working, the radiation interference will become larger, which may interfere with the capacitive screen, and also when the gap is too close, If the capacitive screen itself is not strong enough, the deformation of the press may appear after contacting the display screen, which might result in water ripples or Newton ring. However If the gap is higher than 2mm, our eyes will feel the visual deviation between touch and display, the touch feeling will be greatly affected, and with the gap being too large, it is easy to be affected by external dust if the sealing is not particularly good.
