Patent number: 6806934Abstract: A liquid crystal display (LCD) includes a dielectric multilayer formed inside an LCD cell and a light source behind the LCD cell wherein an image is generated by the LCD in accordance with input video signals when either ambient light is incident on the surface of the dielectric multilayer or when light is generated by the light source. The LCD cell has a first substrate and a second substrate being located facing each other with a liquid crystal layer therebetween. The dielectric multilayer includes multiple layers of transparent dielectric materials with different refractive index. In the LCD of the present invention, since the dielectric multilayer is formed inside the LCD cell, the light only passes through one of the substrates in the reflective mode thereby increasing efficiency while meeting the need for low power consumption.Type: GrantFiled: May 14, 2002Date of Patent: October 19, 2004Assignee: Chi Mei Optoelectronics Corp.Inventors: Hiroyuki Furuhashi, Chung Kuang Wei, Chao Wen Wu

Patent number: 6683660Abstract: A TFT LCD and the method of making the same are provided to prevent short circuits occurred between metal lines and transparent pixel electrodes. An insulating layer is provided to overlay the entire metal layer except the intersection areas for forming contact windows. Then, the transparent conductive layer is provided to form pixel electrodes and interconnection lines. Thus, even transparent conductive layer is not etched clearly and forming residuals, the residuals will not cause short circuits between the metal lines and transparent pixel electrodes. Eventually, the production yield rate can be increased. Moreover, a second metal layer is deposed under the transparent conductive layer to reduce the resistance of the interconnection lines.Type: GrantFiled: November 1, 2000Date of Patent: January 27, 2004Assignee: Chi Mei Optoelectronics Corp.Inventors: Biing-Seng Wu, Chin-Lung Ting, Hiroyuki Furuhashi
