Users doubted what is the difference between industrial touch screen and liquid crystal display?
Simply speaking, the industrial touch screen can be clicked directly, which is convenient and fast. 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 consists of a fixed number of color or black and white pixels, placed in front of a light source or reflector.
There are differences between industrial touch monitors and commercial displays.
(1) In terms of the level of LCD screens, LCD monitors use ordinary display screens, while industrial touch screens use high-brightness industry-grade A+ LCD screens, which require higher backlighting than monitors. Therefore, when the LCD monitor will be blurred when they work for a long time, the image becomes worse. Their performance depends on their production level on the screen also.
(2) The driving scheme is not the same, that is, the display motherboard scheme is not the same. The driving motherboard of the industrial display is better at processing dynamic images. The LCD display adopts the ordinary display motherboard, and the industrial touch screen has to bear long-term work. Therefore, a professional motherboard must be used to ensure higher brightness/contrast/resolution/super high temperature resistance, etc., thereby reducing the use loss of the screen base. If an ordinary display is used for a long time, its brightness and contrast will drop quickly, affecting its service life. This is why most LCD monitors can display images normally after the project has just been debugged, but some of the screen bases will be dark after a period of continuous power-on.
(3) The industrial touch screen has a wide viewing angle, and the large visibility can reach 178 degrees, while an ordinary liquid crystal display can only see one piece at 178 degrees. This is a very important criterion for identifying industrial touch screens and liquid crystal displays. There is also the difference between the two input signals, 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 display. There are BNC, VGA, RGB, HDMI, DVI, S terminals. A variety of other interfaces can meet the input requirements of different signals, while the monitor mainly inputs VGA signals, and the interfaces are mainly VGA, S-terminal, etc., which cannot meet the signal input requirements of various monitoring equipment.
