The On LED backlight, LED display and OLED TFT Display Module difference

LED backlight LED (light emitting diode) as a liquid crystal display backlight, LED-backlit display is liquid crystal display backlight source is traditional CCFL cold cathode fluorescent tube (like fluorescent) transition to LED (light emitting diode). LCD imaging principle can be simply understood as an external voltage is applied to the liquid crystal molecules deflection is just like a camel gate barrier backlights to emit light permeability, and thus the light projected image is formed in a different color filters.Low Temperature Display
Backlight module, the transition from CCFL to LED can bring many benefits, you can let the brightness of the display screen is more uniform, lower power consumption, shape slim and stylish. However, the market is commonly used W-LED (White LED) backlight, the fact the backlight only light-emitting components replaced it, and enhancement of the effect is very weak or does not improve. LCD display enhance the RGB-LED (tri-color LED) to enhance the display effect is more obvious, but the high cost of production, so it is used on high-priced LCD TV. Businessmen said LED display is white LED backlight display products, and liquid crystal display is the difference between the change of the backlight.
LED display is a set of micro-electronics technology, computer technology, information processing in one, its colorful, wide dynamic range, high brightness, long life, stable and reliable, become the most advantage of the public media, LED The display has been widely used in large squares, commercials, sports stadiums, dissemination of information, press releases, securities trading, etc., to meet the needs of different environments.
LED display by controlling the semiconductor light-emitting diode display is probably the way by a number of usually red light-emitting diode, by the bright lights off to display characters. Display screen is used to display text, graphics, images, animation, quotes, video, video signals and other information.
OLED display, along with self-luminous, without backlight, high contrast, thin, wide viewing angle, fast response, can be used in a flexible panel, wide temperature range, excellent characteristics such as structure and process is relatively simple, is considered to be emerging application technology for the next generation of flat panel displays.
The OLED is English OrganicLight-EmittingDiode, Abbreviation, translation is called an organic light emitting diode or an organic light emitting display. Fact, this light-emitting principle as early as in 1936 has been found, but it was not until 1987, Kodak introduced a double-layer OLED devices, OLED only as a commercial and high performance flat panel display technology attracted people's attention. At present, the world has more than 100 research institutions and enterprises into the development and production of OLED display currently on the market giants such as Samsung, LG, Philips, Sony and other companies. Generally speaking, the industrialization of the OLED has begun, including monochrome, multicolor and color device has reached the level of mass production, large-size full-color devices are currently still in the research and development stage, but capacity is still low.Graphic OLED Display
