Background technology
Because liquid crystal indicator (Liquid Crystal Display; LCD) possess that volume is little, high image quality, low consumpting power, advantage such as radiationless; (Cathode Ray Tube, CRT) display device becomes the main flow of display device to have surmounted traditional cathode-ray tube (CRT) in recent years.Yet, to compare with CRT display, liquid crystal indicator needs the backlight can show image usually.General liquid crystal indicator backlight commonly used has cold-cathode fluorescence lamp (Cold-Cathode Fluorescent Lamp, CCFL) backlight and back light source in LED.
White light emitting diode has, and thermal value is low, power saving, but the life-span is long, reaction velocity is fast, volume is little and advantage such as planar package, and it one " white-light illuminating revolution " occur being regarded as.And aspect application market, white light emitting diode because of its power saving, volume is little and reaction velocity is fast etc., and advantage is used on the backlight module of portable display device and TV gradually.Yet; General white light emitting diode commonly used adopts the blue LED chip collocation to go up yttroalumite pomegranate powder (Yttrium Aluminum Garnet more; YAG), though it has the convenient and little advantage of volume of encapsulation, it still is apparent not enough in the performance of color saturation.In addition, because white light emitting diode is a pointolite, the multi-disc blooming piece (like diffusion sheet, light guide plate, brightening piece etc.) of therefore must arranging in pairs or groups can demonstrate uniform surface light source, causes the integral thickness of backlight and manufacturing cost to be difficult to reduce.
In recent years; Existing many developers propose with the design concept of organic electroluminescent element as backlight; To reduce the use of blooming piece; Fig. 1 is Eastman Kodak company and develops two kinds of organic electroluminescent element OLED-1 that, the frequency spectrum of OLED-2, and Fig. 2 is for using organic electroluminescent element OLED-1, the OLED-2 CIE 1931 chromaticity coordinate figure (chromaticity diagram) as the liquid crystal indicator of backlight.
