A touch panel, also known as a touch panel, is an inductive LCD display device that can receive input signals such as contacts. When it comes into contact with graphic buttons on the screen, the touch feedback system on the screen can drive various connecting devices based on pre programmed programs, which can replace mechanical button panels and create dynamic audio and video effects through the LCD display screen.

For common touch screens, they can be classified in the following different ways:

1. According to the production technology of touch screens, they are divided into resistive touch screens, surface capacitive touch screens, surface acoustic touch screens, infrared touch screens, curved wave touch screens, projection capacitive touch screens, as well as optical imaging and active digital converter touch screens.

2. According to the different operation methods of the touch screen, it can be divided into single touch and multi touch. Infrared touch screen utilizes a dense infrared matrix in the X and Y directions to detect and locate user touch.

The infrared touch screen is equipped with a circuit board outer frame in front of the display. The circuit board arranges infrared emission tubes and infrared reception tubes on all sides of the screen, corresponding to a horizontally and vertically crossed infrared matrix. When users touch the screen, their fingers will block the horizontal and vertical infrared rays passing through that position, so they can determine the position of the touch point on the screen.

Question 1: Why does my conference all-in-one machine have touch in some areas and not in others?

Reason 1: Infrared touch has one end emitting and one end receiving. Clicking on the screen with a finger or writing pen in the middle will form a point of disconnected touch. Generally, there are obstacles or dust around the inside of the touch box, which can cause some poor touch; Ensure that there are no obstacles inside the touch box and try cleaning the screen.

Question 2: Why are all my conference tablets touchless? Full screen touch free inspection method:

Reason 2: The motherboard touch cable is inserted backwards. Check if the touch cable is properly inserted at the end of the touch box and check if the touch cable at the motherboard end is inserted upside down; Reverse insertion of the touch cable can directly burn out and cause a full screen without touch. Then you can also use the touch manufacturer‘s software to test. The best way to encounter problems during the use of conference tablets is to call the manufacturer‘s after-sales service, and do not blindly disassemble the device on your own.
