一种高环境对比度(A-CR)和大开口率的显示器已经从理论上证明,并通过把一个正常显黑反射型显示器(NB-RLCD)和一个有机电致发光器件(OLED)堆垛的实验加以证明。这种前后双置(以下称为tandem型)的器件组合可以分别在明亮或昏暗的环境下切换NB-RLCD模式或OLED模式。RLCD的正常显黑特性也可以提升OLED模式工作时的A-CR性能。为了在RLCD模式下获得更好的图像品质,一个复杂并且具有传输功能的结构被用于消除镜面反射和提高可视角至CR﹥2:1超过55°的锥面可视角度。另外,这样的结构也可以提高OLED49.4%的表面量子效率。在我们的实验里,忽略环境亮度因素并使A-CR保持在100:1以上。
A display with high ambient contrast (A-CR) and a large aperture ratio has been theoretically demonstrated by stacking a normally black reflective display (NB-RLCD) and an organic electroluminescent device (OLED) Experiment to prove. This combination of front-back and double-ended (hereinafter referred to as tandem type) devices can switch the NB-RLCD mode or the OLED mode respectively in a bright or dark environment. The normal darkening characteristics of RLCDs also improve A-CR performance when operating in OLED mode. In order to achieve better image quality in RLCD mode, a complex and transportable structure is used to eliminate specular reflection and increase the viewing angle to a viewing angle of the cone of more than 55 ° CR> 2: 1. In addition, such a structure can also improve the surface quantum efficiency of the OLED by 49.4%. In our experiments, we ignored the ambient brightness factor and kept the A-CR above 100: 1.
