Indoor LCD Digital Display utilizes the electro-optical effect of liquid crystal to control the transmittance and reflectivity of the liquid crystal cell through a circuit, thereby producing beautiful images with different grayscale levels and as many as 1,670 million colors.
What is the difference between Indoor LCD Digital Display and LED screen?
How does Indoor LCD Digital Display differentiate between positive and negative displays?
Why not let the Indoor LCD Digital Display be overloaded for a long time?
Indoor LCD Digital Display is a liquid crystal display, and now there are also LED liquid crystal displays, and the difference between them is different in the way of backlighting. Since the liquid crystal itself does not emit light, there must be a light source behind it. In the past few years, fluorescent tube were used. The current trend is to use LED backlits (that is, light-emitting diodes), and now LCD screens using LED backlits are also called LED screens to show the difference.
Monochrome Indoor LCD Digital Display usually has two display types: positive display and negative display. Today, we will take the segment code screen as an example to introduce the difference between these two display types.
1. Positive display
The so-called positive display is that the color of the content displayed on the LCD screen is deeper than the color of the background, such as: black characters on a yellow-green background (yellow-green screen) black characters on a gray-white background (FSTN).
2. Negative display
The so-called negative display means that the color of the displayed content should be lighter than the background color, such as white text on a blue background (blue screen) and white text on a black background (VA segment code screen).
Do not leave the Indoor LCD Digital Display at high brightness for a long time. The display mode of the Indoor LCD Digital Display is different from that of the CRT. The long-time bright picture can easily shorten the life of the backlight tube of the LCD display. Therefore, when not in use for a long time, you should pay attention to turning off the display. In addition, the brightness of the liquid crystal display can be appropriately lowered in daily use. These measures will greatly help extend the life of the LCD monitor.
Second, try to avoid displaying the same screen for a long time. The LCD monitor will cause internal aging or burnout due to long-term work, especially when the same screen is displayed for a long time. Because the LCD display can easily overheat some pixels after working for a long time, once the limit is exceeded, it will cause permanent damage and cannot be repaired. This forms what is often referred to as a "bad spot". Since the pixels of the Indoor LCD Digital Display are composed of liquid crystals, when they work continuously at full load for more than 96 hours, they will accelerate their aging, and even burn out in severe cases.
