Vehicle Touch Display Device Solutions

    With the development of information and electronics, the application of touch-sensitive display panels has become more and more common. At present, touch-sensitive panels have begun to become an industry of their own in the world. As an advanced computer input device, it is currently the simplest , convenient, natural and suitable for multimedia information query equipment, the touch panel has many advantages such as sturdiness and durability, fast response, space saving, easy communication and so on.
 

   However, due to the popularization of VCD/DVD multimedia and satellite navigation GPS in cars, the application of touch-sensitive display panels in cars is becoming more and more common, allowing drivers or passengers to use this technology. Touching the icons or text on the display panel can realize the operation of the host, so that people, vehicles, and machines can interact with each other and enter the system. The new look of multimedia equipment is also a very attractive new multimedia interactive product. This article introduces the related technologies and application solutions of small-size touch display panels for reference.
 

    For the convenience of operation, people use a touch panel to replace the mouse or keyboard. When working, we must first touch the touch panel installed at the front of the display with a finger or other object, and then locate and select the information input according to the icon or menu position touched by the finger. Its main structure is composed of a touch detection component and a touch panel controller. .
 

    The touch detection component is installed in front of the display panel to detect the user's touch position and receive the touch screen controller; the main function of the touch screen controller is to receive touch information from the touch point detection device and convert it into contact coordinates. Then send it to the CPU, it can also receive the command sent by the CPU and execute it.
 

    As far as the current market touch panel is concerned, it can be mainly divided into five basic types; from the technical principle to distinguish the touch panel, it can be divided into: pressure sensing technology touch panel, resistance technology touch panel, capacitive touch panel Technology touch panel, infrared technology touch panel, surface acoustic wave technology touch panel.
 

    Among them, the pressure sensing technology has been withdrawn from the market; although the price of infrared technology is low, the outer frame is easily damaged, resulting in light interference, and it is easy to be distorted on curved surfaces; capacitive design theory is good, but the problem of image distortion is difficult to fundamentally solve; resistance The positioning method is accurate, but the price is high, and the panel is easy to be damaged; the surface acoustic wave touch screen solves various defects of the previous touch screen, the picture is clearer and has anti-riot effect, suitable for various occasions, but the main disadvantage is that once the panel has water droplets or Dust can make the panel unresponsive or even not working.
