TFT LCD industrial liquid crystal screen is a kind of high-tech products with liquid crystal material as the main production material, which has the advantages of small size, light weight, bright color, high contrast, low power consumption, fast response, low working voltage, long service life and so on. In the industrial field, it is widely used in the LCD display of mechanical equipment, instruments and electronic instruments.
TFT LCD industrial LCD screens are divided into TFT-TFT LCD screens and TN LCD screens according to material. TFT-TFT LCD screen liquid crystal molecules are arranged in parallel, each pixel has an independent color and brightness, each scan is a color change, each pixel has an independent brightness and contrast, so that you can achieve pixelated LCD display. The TN liquid crystal molecules are arranged vertically, and each pixel has the same brightness and contrast.
Step 1: Structure
TFT LCD industrial LCD screen is mainly composed of a substrate, a LCD screen, a drive circuit and a key. The substrate is the main structure of the TFT LCD industrial liquid crystal screen, which is composed of a number of liquid crystal boxes of different sizes, and the liquid crystal box is installed with polarizer, polarizer and resistance elements to achieve the liquid crystal display. The LCD screen is used to display graphics and text, which is mainly composed of backlight plate, TFT and drive circuit. The driver circuit is the main part of the data interaction between the TFT LCD industrial LCD screen and the outside world, and controls the display content of the display screen, which is generally divided into DC dimming and AC dimming.
Step 2 Put on a show
The performance of TFT LCD industrial LCD screen mainly includes stability, anti-interference, display effect and response speed, stability refers to the LCD screen in the use of the process will not flicker, crash and other phenomena, anti-interference means that the LCD screen in the use of the process will not be interfered by external light, display effect refers to the LCD screen in the display of different brightness images, Whether the characters on the screen are clear and undistorted; Response speed refers to the response time of the LCD screen to the input signal.
Step 3: Characteristics
1. Liquid crystal display response speed is fast, at 0% brightness, response time can reach more than 200 nits.
2. LCD display has high contrast, more colorful display, and more real display picture.
3. Liquid crystal display small size, light weight, easy to carry.
Step 4 Apply
TFT LCD industrial LCD screen is widely used in a variety of industrial production equipment, instruments and electronic instruments, such as CNC machine tools, injection molding machines, printing machinery, laser processing equipment, CNC machine tools, woodworking machinery, electronic instruments, medical equipment and other equipment, these equipment need intelligent control, At the same time, the processing results need to be monitored in real time during use, so the application of TFT LCD industrial liquid crystal screen is needed to facilitate the real-time monitoring of equipment status.
In the industrial field of TFT LCD industrial LCD screen size is also different, there are 8 inch screen, 10 inch screen and 16 inch screen. In addition, because the working voltage of the TFT LCD industrial liquid crystal screen is very low, it can also be used in instruments.
5. Use precautions
1, when there is dust on the surface of the product, it should be wiped with a clean and soft rag, and it is strictly prohibited to use hard objects to wipe the LCD screen.
2, it is strictly prohibited to apply any form of electromagnetic field on the product, and it is strictly prohibited to place magnetic parts above the product.
3, do not let the product contact with corrosive substances. Do not spray corrosive liquid directly into the TFT LCD to avoid corrosion of the internal components of the TFT LCD.
4, magnetic components can not be put together with magnetic TFT liquid crystal components, so as to avoid magnetic interference.
5, when the product is installed on the machine equipment, the back of the panel can not be directly in contact with the metal parts to avoid the metal parts hitting the panel, resulting in short circuit of the panel.
6, the product can not be directly in contact with humid air, avoid placing the product with moisture in a humid environment, so as to avoid the panel moisture caused by adverse phenomena.
