Description
Technical field
The present invention relates to flat panel display, particularly a kind of organic light-emitting display device and manufacture method thereof.
Background technology
In recent years, due to white organic LED (White Organic Light Emitting Diode, WOLED) can make the light source sheet that paper is equally thin, and can be used for doing backlight and all colour organic luminous display unit of liquid crystal display, therefore, white organic LED becomes a kind of important Display Technique gradually.
Conventionally, all colour organic luminous display unit has been continued to use liquid crystal indicator (Liquid CrystalDisplay, LCD) principle of true color, utilize white organic LED luminous, re-use color filter film and leach three primary colors, in conjunction with the colorized optical filtering chip technology of maturation of existing market volume production technology, realize true color and show.
As shown in Figure 1, all colour organic luminous display unit 1 of prior art drives evaporation organic luminous layer 12 on layer 11 at the thin-film transistor of array base palte, collocation color filter film substrate 13(Color Filter, CF) realize full-color demonstration.After organic luminous layer 12 is excited, send white light L, white light L sees through color filter film substrate 13 and shows respectively blue (B) the three kinds of colors of red (R) green (G).But owing to being not to fit completely between color filter film substrate 13 and array base palte 10, be scattered with sept 14 between the two to support, therefore, between color filter film substrate 13 and array base palte 10, have the existence in box gap 141.In the time that organic luminous layer 12 parts of sub-pixel corresponding to tri-kinds of colors of RGB are lighted, there will be mixed color phenomenon.Concrete, as shown in Figure 1, suppose to only have the organic luminous layer 12 of the sub-pixel that G is corresponding to be lit, the organic luminous layer 12 of the sub-pixel that R and B are corresponding is in closed condition, owing to there being box gap 14 between substrate, the white light L that M point sends should only pass through G color filter film, but when larger at light inclination angle, also have R color filter film and the B color filter film of part white light L from color filter film substrate 13 and appear.
Shown in Fig. 2, in the time that visual angle tilts to 70 °, the brightness of all colour organic luminous display unit 1 is about 60% of high-high brightness, with great visual angle time, all colour organic luminous display unit 1 still has higher brightness, and therefore display frame meeting produces more serious mixed color phenomenon.In addition, because white light L is divergent shape outgoing, the light that makes finally to be sent by G color filter film only accounts for a part of the white light L that M point sends, and another part white light L is by R color filter film and the ejaculation of B color filter film or be lost in box gap 14, thereby causes the reduction of white light utilance.
