Differences and advantages between LED display and LCD

LED applications can be divided into two categories: First, single-tube LED applications, including the backlight LED, infrared LED, etc.; The other is the LED display, present, basic materials in the manufacture of LED, there are still some international gap, but on the LED display, China's basic design and production technology level and the international LED application can be divided into two categories: First, single-tube LED applications, including the backlight LED, infrared LED, etc.; The other is the LED display, present, China LED based materials with the international there are still some gaps, but LED display, China's basic design and production technology with international standards.

LED display is formed by the light-emitting diodes arranged in a display. It uses low-voltage scan driver, with: power consumption, long life, low cost, high brightness, less failure, view big, visible from far away and so on. Compared with LCD displays LED displays, LED brightness, power consumption, viewing angle and the refresh rate, etc., have more advantages. LED and LCD power consumption ratio of about 10:1, and higher refresh rate makes the LED in the video have better performance, to provide wide angle of 160 °, you can display a variety of text, numbers, color image and animation information, can also play TV, video, VCD, DVD and other color video signal, multiple displays can be networked broadcast.

Individual elements of the organic LED display LCD LCD screen response speed is 1,000 times in the bright light can not stop watching, and adapt to the low temperature of minus 40 degrees. Using LED display technology, can produce thinner than the LCD, brighter, clearer displays with a wide range of applications. LCD is liquid crystal display of the name: it includes a TFT, UFB, TFD, STN and other types of liquid crystal display. Commonly used in notebook LCD screen is TFT. TFT screen is thin film transistor, the English full name (ThinFilmTransistor), is a type of active matrix liquid crystal displays, set back in its special fluorescent tubes can take the initiative on the screen to control each individual pixel, which is called the origin of active matrix TFT This can be greatly improved What time is about 80 ms, 200 ms for the STN! also improved STN flash (ripple) blurred, effectively improve the ability of playing the dynamic images, and STN-phase ratio, TFT has excellent color saturation, reducing power and higher contrast, the sun is still very clear to see, but the drawback is more power and higher cost. Simply put, LCD and LED are two different display technologies, LCD is composed of liquid crystal display, the LED is formed by the light-emitting diode display. Compared with LCD displays and LED displays, LED brightness, power consumption, viewing angle and the refresh rate, etc., have more advantages
