To put it simply, the industrial touch screen can be directly clicked, which is convenient and quick. It is the tactile feedback function in the touch screen system of the industrial touch LCD display. Liquid crystal display is a flat and ultra-thin display device, which is composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. The following is a brief introduction.
The difference between industrial touch screen and LCD display:
1. In terms of the level of the LCD screen, the LCD screen uses an ordinary display screen, while the industrial touch screen uses a high-brightness industrial-grade A+ LCD screen, which has higher requirements for the backlight than the monitor. Therefore, when the LCD screen It will be blurry on the display screen, and cannot achieve a good image effect;
2. The drive scheme is different, that is, the display motherboard scheme is different. The driver motherboard of the industrial display screen is mainly better at handling dynamic images. Long-term work, so a professional motherboard must be used to ensure high brightness, contrast, clarity, super high temperature resistance, etc., thereby reducing the use of the screen. If the ordinary display screen is used for a long time, its brightness and contrast will drop rapidly, which will affect its service life. This is why most LCD screens can display images normally after the project has just been debugged, but some screens will become dark after a period of continuous startup. the
3.The industrial touch screen has a wide viewing angle, and the maximum visibility can reach 178 degrees, while ordinary LCD screens can only see one piece in the direction of 178 degrees. This is a very important criterion for identifying industrial touch screens and LCD displays. In addition, the input signals of the two are different, mainly the input video signal. In order to meet the interface requirements of different front-end devices, the interface of the monitor will be much richer than that of the monitor, including BNC, VGA, RGB, HDMI, DVI, S terminal, etc. A variety of interfaces meet the input requirements of different signals, while the display screen mainly inputs VGA signals, and the interfaces are mainly VGA, S terminals, etc., which cannot meet the signal input requirements of various monitoring equipment.
