Touch screen resistive screen and capacitive screen, capacitive screen is divided into infrared screen, capacitive touch screen
. Let's talk about the trend of the touch screen: 1. Touch pen: In the early days, the touch pen only provided a light pen for menu selection. The function of the light pen has been greatly enhanced. The touch screen operated with a touch pen is similar to a whiteboard. In addition to the display interface, windows, and icons, the touch pen also has the functions of signing and marking. 2. Touchpad: The touchpad uses pressure-sensitive capacitive touch technology with the largest screen area. It consists of three parts: the bottom layer is the center sensor, which is used to monitor whether the touchpad is touched, and then process the information; the middle layer provides interactive graphics, text, etc.; the outermost layer is the touch surface layer, which has high intensity Made of plastic materials. When the finger touches the outer surface, the information can be sent to the sensor within 1/1000s, and the login process can be performed. In addition to being compatible with PCs, it also has the characteristics of high brightness, clear images, and easy interaction. Therefore, it has been applied to pointing information query systems (such as electronic bulletin boards) and has received very good results. 3. Touch screen: The touch screen is simply the combination of input and output, no mechanical buttons or sliders are needed, and the display is a man-machine interface. The entire touch screen system is composed of LCD screen, touch screen, touch screen controller, main CPU, and LCD controller. The multi-touch screen main control board is the core of the touch screen module. The touch screen controller adopts PSoC (Programmable System Chip) technology. PSoC is a mixed-signal array that integrates programmable analog and digital peripherals and MCU core, so the flexibility of PSoC , Programmability, high integration and other characteristics are widely used in touch screen controllers. The touch screens currently built are 32, 46 and 70 inches, support 1080p FullHD resolution, and can support multi-touch control without any additional settings, and can be placed vertically or horizontally. More convenient is that it uses standard HDMI, FireWire and USB interfaces, plug in the power and connect to a Mac, Linux or Windows PC to start using. Rongguan touch screen manufacturer
