Abstract
Description
本創作是有關於一種有機發光顯示器，特指一種具有可降低反射光色偏及強度之補償膜之有機發光顯示器。The present invention relates to an organic light emitting display, and particularly to an organic light emitting display having a compensation film capable of reducing the color shift and intensity of reflected light.
隨著人們對於手持裝置的視覺效果感受，如色彩飽和度等更加要求，有機發光顯示器的應用與需求因此增加，而有機發光顯示器雖然具備自發光能力，不需額外添加背光源，但於戶外等高光比環境下，容易因有機顯示面板之金屬電極或高折射率材料反光，使顯示器之對比大幅下降。As people's visual effects on handheld devices, such as color saturation, are more demanding, the application and demand for organic light-emitting displays are increasing, while organic light-emitting displays have self-illuminating capabilities, and do not require additional backlights, but are outdoors. In the high light ratio environment, it is easy to reflect the metal electrode of the organic display panel or the high refractive index material, so that the contrast of the display is greatly reduced.
請參考第1圖，其為習知改善方式，以感壓膠等黏著層4貼附一圓偏光板7作為補償膜於該有機顯示面板1之表面，而該圓偏光板7一般係以一偏光層6貼附一位相差值為+λ/4或-λ/4之位相差膜5而形成，當外界光源10穿過圓偏光板7時，可轉變為圓偏光11，經過該有機顯示面板1之反射會再轉變為相反旋轉方向之反射光12，並藉由圓偏光板7再次轉換反射光線之偏振方向為與偏光層6之吸收軸同向而吸收，以減少反射光線到達使用者眼睛，使顯示器之對比度增加；而習知位相差膜5僅針對一特定波長補償，例如為綠光，但一般具有彩色濾光片3之有機發光顯示器，仍具備紅光區R、綠光區G及藍光區B之子像素，若僅補償單一綠色波長，則紅色及藍色之反射光不易被偏光層6吸收，仍會被使用者所 看見，故容易感受該有機發光顯示器之反射光色相具有色偏。Please refer to FIG. 1 , which is a conventional improvement method, in which a circular polarizing plate 7 is attached as a compensation film on the surface of the organic display panel 1 with an adhesive layer 4 such as a pressure sensitive adhesive, and the circular polarizing plate 7 is generally polarized. The layer 6 is formed by attaching a phase difference film 5 having a difference of +λ/4 or -λ/4, and when the external light source 10 passes through the circular polarizing plate 7, it can be converted into circularly polarized light 11 through the organic display panel. The reflection of 1 will be converted into the reflected light 12 in the opposite direction of rotation, and the polarization direction of the reflected light is again converted by the circular polarizing plate 7 to be absorbed in the same direction as the absorption axis of the polarizing layer 6, so as to reduce the reflected light reaching the eyes of the user. The contrast of the display is increased; whereas the conventional phase difference film 5 is only compensated for a specific wavelength, for example, green light, but the organic light-emitting display generally having the color filter 3 still has the red region R and the green region G. And the sub-pixel of the blue region B, if only a single green wavelength is compensated, the red and blue reflected light is not easily absorbed by the polarizing layer 6, and will still be used by the user. When it is seen, it is easy to feel that the reflected light hue of the organic light emitting display has a color shift.
故本創作之創作人針對習知有機發光顯示器之結構進行改善，將習知有機發光顯示器補償膜之位相差膜，依照紅色、綠色及藍色之不同子像素位置，因應形成不同+λ/4或-λ/4之反射光波長位相差值，以同時補償不同波長之反射光，使反射光不易色偏，且因消除較習知技術更多不同波長之反射光，而可進一步增加該有機發光顯示器之對比。Therefore, the creator of the present invention has improved the structure of the conventional organic light-emitting display, and the phase difference film of the conventional organic light-emitting display compensation film is formed according to different sub-pixel positions of red, green and blue, and different +λ/4 is formed accordingly. Or the wavelength difference of the reflected light of -λ/4 to compensate the reflected light of different wavelengths at the same time, so that the reflected light is not easy to be color-shifted, and the organic light can be further increased by eliminating more reflected light of different wavelengths than the conventional technology. Comparison of illuminated displays.
