    • Liquid crystal display devices having display screens with an improved black frame is provided. The microdisplay of the LCD is formed of a matrix of pixels disposed on the top surface of a silicon substrate, a layer of glass, and a layer of a reflective metal, preferably aluminum, which is disposed between the silicon substrate and layer of glass. The layer of reflective metal has a pattern, which forms a frame around the matrix of pixels, and is involved in generating the black frame when viewed by the user on the display screen. The reflective material functions to reflect light back to the light generating source, and thus displays a pure black image to the user. In another embodiment, a layer of reflective metal, preferably black chromium, patterned to form a frame around the matrix of pixels, is disposed on the top surface of the glass. The reflective metal layer on top of the glass may be used either in place of, or in addition to, the reflective metal layer on the bottom of the glass to generate the improved black frame.
    • 提供了具有改进的黑框的显示屏的液晶显示装置。 LCD的微型显示器由布置在硅衬底,玻璃层的顶表面上的像素矩阵和设置在硅衬底和玻璃层之间的反射金属(优选铝)的层构成。 反射金属层具有在像素矩阵周围形成框架的图案,并且在用户在显示屏幕上观看时涉及生成黑框。 反射材料用于将光反射回发光源,从而向用户显示纯黑色图像。 在另一个实施例中,在玻璃的顶表面上设置一层被图案化以形成围绕像素矩阵的框架的反射金属,优选黑色铬。 可以将玻璃顶部上的反射金属层用于代替玻璃底部的反射金属层,或者代替玻璃底部的反射金属层,以产生改进的黑色框架。
