Indoor LCD Digital Display is a liquid crystal display, which is a display device, which consists of two upper and lower glass, polarizer, liquid crystal and ITO film, etc.
What are the advantages of Indoor LCD Digital Display?
What are the main structural components of Indoor LCD Digital Display?
What should I pay attention to when using the Indoor LCD Digital Display?
Advantages of Indoor LCD Digital Display:
(1) Since the CRT display relies on the electromagnetic field generated by the deflection coil to control the electron beam, and because the electron beam cannot be absolutely positioned on the screen, the CRT display often has different degrees of geometric distortion and linear distortion. The Indoor LCD Digital Display will not have any geometric distortion and linear distortion due to its principle, which is also a great advantage.
(2) Compared with the traditional CRT, the liquid crystal also performs well in terms of environmental protection. This is because there are no high-voltage components like the CRT in the Indoor LCD Digital Display, so it will not cause the x-ray exceeding the standard due to high voltage. Therefore, its radiation index is generally lower than that of CRT.
(3) Compared with traditional CRT, the biggest advantage of Indoor LCD Digital Display lies in power consumption and volume. For traditional 17-inch CRT, its power consumption is almost above 80W, while the power consumption of 17-inch LCD is mostly At around 40W, it can be said that LCD has obvious advantages in energy saving.
The structure of Indoor LCD Digital Display is from inside to outside: color filter and lattice, TFT, backlight.
The color filter has three colors of RGB, and a group of three colors constitutes other colors. It is not visible visually from a distance, and a group of three colors can be seen from a distance.
The lattice sheet is to separate the light paths between each color so that it does not cause light to diffuse into the light paths next to it.
TFT, thin film transistor, controls the intensity of light transmitted through each lattice, thereby controlling the intensity of each color. After passing through the filter, it forms a visual color because of the difference in intensities of the three colors.
The backlight is a reflector, usually with light bars (lighting) on four sides.
Moisture is the natural enemy of liquid crystal. If the humidity is too high, condensation will occur inside the liquid crystal display. After condensation, leakage and short circuit will occur, and the liquid crystal display will become blurred. Therefore, do not put the LCD monitor in a humid place, and do not let anything with moisture enter the LCD monitor. If you find that only the surface of the screen is foggy before turning it on, wipe it gently with a soft cloth; if moisture has entered the LCD display, you can turn off the display, turn the Indoor LCD Digital Display away from the sun, or use a desk lamp to bake the inside. The water can evaporate. But be careful not to expose the Indoor LCD Digital Display to sunlight, which will cause the aging of components. If there is a more serious moisture incident, it is better for ordinary users to get in touch with the local brand after-sales service providers and ask them for help to be more secure. Because the more serious moisture will damage the components of the LCD, when the user turns on the Indoor LCD Digital Display with high humidity, it will cause the liquid crystal electrodes to corrode and cause permanent damage.
