1. Classification of LCD splicing screen and LED splicing screen
1. LCD screens mainly include TFT, UFB, TFD, STN and other types of LCD splicing screens.
2. LED is a light emitting diode. LED applications can be divided into two categories: one is led display screen; the other is led single tube single tube application, including backlight led, infrared led and so on. At present, for LED displays, it has the following characteristics: low power consumption, long service life, low cost, high brightness, low failure, large viewing angle, and long viewing distance.
2. Comparison of LED splicing screen and LCD splicing screen
Compared with LCD screens, LCD screens have advantages in brightness, power consumption, viewing angle and refresh speed. Using led technology, LCDs can be made thinner, brighter, and clearer displays.
1. The power consumption ratio of LED and LCD is about 1:10, LED is more energy-saving.
2. The LED refresh speed is higher and the video performance is better.
3. The LED provides a wide viewing angle of 178°, which can display a variety of text, numbers, color images and animation information, and can play color signals such as TV, audio, and pictures.
4. The reaction speed of a single element of the LED display is 1000 times that of the liquid crystal display, which can be correctly irradiated under strong light and adapt to the low temperature of minus 30 degrees.
