What is the difference between TFT and Indoor LCD Digital Display?
When purchasing Indoor LCD Digital Display, there are several basic pointers: High brightness: The higher the brightness value, the brighter the picture will be without hazy fog. The unit of brightness is cd/m2, which is the number of candles per square meter. Low-end LCD brightness values can be as low as 150 cd/m2, while high-end displays can be as high as 250cd/m2. High Contrast: The higher the contrast, the more vivid and saturated the color, and the three-dimensional will appear. Conversely, the contrast is low, the colors appear barren, and the image becomes flat. Contrast values vary widely, ranging from as low as 100:1 to as high as 600:1, or even higher. Wide viewing range: Simply speaking, the viewing range refers to the clear range in which the screen can be seen in front of the screen. The larger the viewing range, the easier it is to see; the smaller the viewing area, the picture may become unclear as long as the viewer changes the viewing position slightly. The algorithm of the visible range of the Indoor LCD Digital Display is from the middle of the screen to the clear angle range of the screen in four directions: up, down, left and right. The larger the value, the wider the range, but the range in the four directions is not necessarily symmetrical.
The liquid crystal state is sandwiched between two transparent electrode substrates. When the thickness of the liquid crystal is less than several hundred microns, the liquid crystal molecules near the interface are oriented and maintained in order. When a controlled electric field direction is applied to the electrode substrate, a series of electro-optics are generated The regular orientation of the liquid crystal molecules changes accordingly. The regular orientation of liquid crystal molecules includes parallel orientation, vertical orientation and oblique orientation. The orientation of liquid crystal molecules changes, that is, anisotropy of refractive index occurs, resulting in optical reactions such as light scattering effect, optical rotation effect, and birefringence effect. This is the most basic imaging principle of Indoor LCD Digital Display.
TFT is one of the various display technologies of LCD liquid crystal screens. A direct comparison cannot be made. Only the differences between these display technologies in the LCD camp can be compared, as follows:
1. Indoor LCD Digital Display is characterized by low price and widespread use. It needs backlight support when displaying.
In the main screen material of the mobile phone parameter table, you often see some letter combinations such as TFT, IPS, SLCD, UFB, SNT, NOVA, etc. They do not represent different screen materials, but rather different display technologies for LCD.
2. TFT (Thin Film Transistor) is a thin film field effect transistor, which is one of the active matrix liquid crystal displays.
TFT liquid crystal display is characterized by good brightness, high contrast, strong sense of hierarchy, and bright colors, but it also has the disadvantages of relatively power consumption and high cost.
