  •      The touch all-in-one is a set of advanced touch screen, motherboard, memory, hard disk, graphics card and other electronic components, which is the same as the working principle of traditional PC. The capacitive touch all-in-one, as the "fifth media" that has always been recognized, its appearance in the advertising industry can be described as a household name, and it has been increasingly recognized and used by the advertising industry.
  •  
  •      As a high-tech machine, the touch all-in-one has gradually replaced the status of a simple touch screen, so that users can truly feel the characteristics of human-computer interaction. As long as the user touches the screen of the machine lightly with a finger, the user can quickly get the information he wants, thereby making the human-computer interaction more straightforward.

The 12V socket (white) is the power supply line, and the 5V socket (blue) is the power supply socket of the infrared screen. If the wrong plug is inserted, the driver card, infrared screen, and LCD will burn out. Third, the LCD screen socket and plug must not be wrong. The white or red plug should be marked with the triangle of the socket. It cannot be reversed and cannot be misplaced. The plug on the LCD port cannot be reversed. The flat iron side is attached to the LCD socket (inside). When dialing the socket, press two The corner clips are pulled out and cannot be hard dialed.
