23.8-inch TP Capacitive Touch Screen

The capacitive touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connected devices according to pre-programmed programs. It replaces the mechanical button panel, and uses the liquid crystal display screen to create moving audio and video effects. It gives multimedia a new look and is a very attractive new multimedia interactive device. Mainly used in the query of public information, leadership office, industrial control, military command, miners, navigation, video games, multimedia teaching and other industries

IV Note when using TP capacitive touch screen:


     1. Interference issues. Since the capacitive screen realizes the touch function by detecting the change of the capacitive signal on the touch surface, it is easy to be interfered by the external electromagnetic environment. Therefore, the capacitive screen should be kept away from the interference source, and the interference source mainly comes from the LCD screen and the power supply. When installing, it is recommended that the large-sized capacitive screen and the LCD screen be kept at a distance of more than 1.5mm. The power supply is also recommended to choose a power supply of good quality as far as possible to prevent the interference signal from being too strong to touch properly.

     When single tp is tested. Please test the insulation material (such as foam, etc.) under the tp first, and then replug the usb cable after moving the tp or plugging the fpc during the test to ensure normal touch.

    

 2. The TP is damaged due to improper operation. Because the back side of the TP is directly outside, it is easy to be damaged by hard objects, so please handle it gently. In addition, fpc is also a relatively fragile part, and the intensity should be soft when folding, so as to avoid dead folds.

     

3. The touch effect is not ideal. For example, there are random jump points, disconnections, and slow response speeds. Please do not worry, because the samples are only debugged for a single tp, which may be different from the overall environment. Large, need to be optimized for the whole machine.
