|LED display and LCD display difference and advantages|
Led applications can be divided into two categories: one is LED single-tube applications, including backlight LEDs, infrared LEDs, etc.; the other is LED display, at present, China has a certain gap in the manufacture of LED basic materials and the international, but As far as LED displays are concerned, China's design and production technology levels are basically in line with international standards.
The LED display is a display device consisting of an array of light emitting diodes. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, less failure, large viewing angle and long visible distance.
Compared with LCD displays, LED displays have advantages in terms of brightness, power consumption, viewing angle and refresh rate. The power consumption ratio of LED to LCD is about 10:1, and the higher refresh rate enables LEDs to perform better in video, providing a viewing angle of up to 160° and displaying various text, digital, and color images. And animation information, you can also play TV, video, VCD, DVD and other color video signals, multiple screens can also be broadcast online. The single element of the organic LED display has a reaction speed of 1000 times that of the LCD screen. It can also be taken under strong light and is suitable for low temperatures of minus 40 degrees. LED technology can be used to produce displays that are thinner, brighter, and clearer than LCDs, and have broad application prospects.
LCD is the full name of liquid crystal display: it includes TFT, UFB, TFD, STN and other types of liquid crystal display.
The LCD screen is commonly used in TFT. The TFT screen is a thin film transistor, the full name of the film (ThinFilmTransistor), is an active matrix type liquid crystal display, and a special light pipe is arranged on the back thereof to actively control individual pixels on the screen, which is also the origin of the so-called active matrix TFT. This can greatly improve the time, about 80 milliseconds, and the STN is 200 milliseconds! It also improves the STN flicker (water ripple) blur, effectively improving the ability to play dynamic pictures, compared with STN, TFT has excellent color saturation, reducing power and higher contrast. It is still very clear under the sun, but the disadvantage is that it consumes more power and costs.
Simply put, LCDs and LEDs are two different display technologies. LCDs are displays made up of liquid crystals, while LEDs are displays made up of light-emitting diodes. Compared with LCD displays, LED display walls have advantages in terms of brightness, power consumption, viewing angle and refresh rate
