OLED Module technology and development with echoes, OLED drive also plays an increasingly important role. Not only from the low duty cycle increases to support high duty cycle, and the application of such a control current for each RGB, wider IC operating temperature (-45 to 80 ℃), the internal DC-DC boost, as well as graphics acceleration instruction and some other features.

White LED light-emitting mechanism and characteristics TFT Display Module
A light-emitting mechanism
The single-chip white LED containing InGaN active layer the CaN emitting diode, it mainly has two light-emitting mechanism: one is a combination of a blue LED and a phosphor to produce white light, the yellow light emitted by blue and phosphorus mixed; another The species is through the combination of the ultraviolet LED and red, blue, and green phosphor to produce white light.OLED Module
2 Features
White LED main characteristics are: forward voltage drop to 3.5 V; luminous efficiency of 20lm / W, better than incandescent bulbs, inferior to fluorescent lamps (601m / W to 100 lm / W), 2004, the luminous efficiency can be increased to 60lm / w, close to the level of fluorescent lamps, which can be used extensively for the lighting market; the luminous flux 231m; small package size. White LED lighting market are enticing, the world LED manufacturers stepping up the development of high-power white LED, such as the development of high-power InGaN LED power up to 1 W to 2 W the existing LED 10 times. University of California, solid state lighting and display center plan developed before 2007 departure optical efficiency of 200lm / W white LED.TFT LCD Display
