Description
Technical field
The present invention relates to a kind of modified model parallel all colour organic electroluminescence display apparatus and preparation method thereof, not only can effectively improve light source penetrance and color saturation, can improve the rate of manufacturing a finished product again.
Background technology
In numerous displays, how to reach the technology key of this display development success or not often, and with regard to organic electroluminescence display device (OLED), reaching the modal method of full-color Presentation Function there are following two kinds with full-color display effect:
1. the three primary colors independent pixel is luminous: can produce red (R), green (G) respectively, blue (B) trichromatic organic EL component independently is provided with, and these three kinds of coloured light are produced full-color display effect with the proper proportion mix and match.
Yet, because this organic electroluminescence display device need produce the organic light-emitting units of different color light via the step of repeatedly evaporation and shielding contraposition when making, not only production process is comparatively loaded down with trivial details, and the requirement to accuracy when evaporation or shielding contraposition also improves relatively, easier so and reduction product yields and the relative cost of manufacture that improves.
2. colored filter (Color Filter): be provided with at least one organic EL component that produces white light source, the skillful colored filter of collocation operation technique, reach the purpose of the light color filtering of white light source by colored filter, thereby produce full-color display effect.
The general using colored filter carries out the organic electroluminescence display device of light color filtering, as shown in Figure 1, colored filter 10 mainly is that a transparency carrier 11 is provided with a black matrix" 13 (BlackMatrix), and be provided with a chromatic filter layer 15 with light color filtering function at transparency carrier 11 upper surfaces that are not provided with black matrix" 13, include the first colored photoresist 151 (G), the second colored photoresist 153 (B) and the 3rd colored photoresist 155 (R).Have again, above black matrix" 13 and chromatic filter layer 15, optionally be provided with a planarization layer 17 (Over Coat) or again and block layer, be beneficial to the carrying out of subsequent technique.
When the general using colored filter carries out full-colorization demonstration, will filter out the white light source of suitable vast scale, cause the display brightness deficiency of this organic electroluminescence display device and the waste of power supply, and the device luminous for the three primary colors independent pixel, as Fig. 1, mainly be that upper surface at a transparency carrier 11 is respectively arranged with one first organic light-emitting units 231, second organic light-emitting units 233 and the 3rd organic light-emitting units 235, wherein, the first light source S1 that each organic light-emitting units 23 is produced, secondary light source S2 and the 3rd light source S3 are respectively a red light source, green light source and blue-light source can reach the purpose of the full-colorization demonstration of this organic electroluminescence display device display unit 200 by the trichromatic mix and match of proper proportion.
Have again, before this organic light-emitting units 23 is set above this transparency carrier 11, need carry out a shielding contraposition program earlier, wherein, shielding contraposition program is if error occurs, will directly influence the setting of this organic light-emitting units 23, for example, the shielding contraposition program of this second organic light-emitting units 233 is inaccurate, will make the position that is provided with of this second organic light-emitting units 233 deviation occur, and be provided with and produce an error band 239 on the position in former part that should second organic light-emitting units 233, owing to be not provided with this second organic light-emitting units 233 on this error band 239, therefore this error band 239 can't produce secondary light source S2, cause the active area of this second organic light-emitting units 233 to reduce, be reduced to light-emitting area A2 by original light-emitting area A1, thereby influence the luminosity of this secondary light source S2 and the display quality of this display unit.
For this reason, how at problem that above-mentioned known technology ran into, design modified model parallel all colour organic electroluminescence display apparatus of a kind of novelty and preparation method thereof, the rate of finished products loss that causes in the time of can overcoming evaporation process and shielding contraposition, not only can reduce cost of manufacture and help the lifting of finished product rate, with the effect that improves its light source penetrance color saturation, be invention emphasis of the present invention again.
