Patent number: 7884911Abstract: A FFS semi-transmissive LCD comprises a first substrate and pixel matrix. The pixel matrix is disposed on the first substrate and comprises a plurality of pixel units. Each pixel unit comprises a counter electrode, pixel electrode layer, reflection layer and liquid-crystal disposition layer. The counter electrode is disposed on the first substrate. The pixel electrode layer is disposed above the counter electrode. The reflection layer is disposed between the first substrate and pixel electrode layer. The reflection layer is smaller than the counter electrode in area. The liquid-crystal disposition layer is disposed on the pixel electrode layer and comprises a transparent material layer. The transparent material layer is smaller than the liquid-crystal disposition layer in thickness and has substantially the same shape and area as the reflection layer, and the transparent material layer and the reflection layer are face-to-face disposed at two opposite sides of the pixel electrode layer.Type: GrantFiled: September 17, 2007Date of Patent: February 8, 2011Assignee: Wintek CorporationInventors: Yi-Chun Wu, Chian-Chang Lee, Chin-Chang Liu

Patent number: 7728929Abstract: A transflective liquid crystal display device includes a first and a second substrates, a liquid crystal layer, and a plurality of reflective electrodes and transparent electrodes. The liquid crystal layer is interposed between the first and the second substrates and functions in an OCB mode. The reflective electrode and the transparent electrode in one picture element are spaced apart from each other to produce a transverse electric field when a voltage is applied across the liquid crystal layer.Type: GrantFiled: October 6, 2006Date of Patent: June 1, 2010Assignee: Wintek CorporationInventors: Yi-Chun Wu, Wen-Jui Liao, Chin-Chang Liu, Chian-Chang Lee

Patent number: 7619707Abstract: A multi-domain liquid crystal display includes a first and a second substrates, and a liquid crystal layer is interposed between the first and the second substrates. A first common electrode is formed on an entire surface of the first substrate. A first dielectric layer is formed on the second substrate and covers first signal lines, and a second dielectric layer is formed on the first dielectric layer and covers second signal lines. A plurality of pixel electrodes are formed on the second dielectric layer, and a plurality of second common electrodes are formed on the second substrate, where a voltage difference existing between the second common electrodes and the pixel electrode produces fringe fields.Type: GrantFiled: November 27, 2006Date of Patent: November 17, 2009Assignee: Wintek CorporationInventors: Wen-Chun Wang, Chian-Chang Lee, Chin-Chang Liu, Ying-Cheng Tsai, Yi-Lin Chou

Publication number: 20080106658Abstract: A multi-domain liquid crystal display includes a plurality of picture elements arranged in an array of rows and columns and controlled by a line inversion drive scheme. Each picture element has a pixel electrode and at least one control electrode insulated from each other. All the control electrodes in the same row or the same column of picture elements are connected to the same signal source to provide a voltage difference between the control electrodes and the pixel electrodes in the same row or the same column of picture elements to produce fringe fields.Type: ApplicationFiled: October 30, 2007Publication date: May 8, 2008Inventors: Wen-Chun Wang, Wan-Jen Tsai, Min-Chang Yu, Chian-Chang Lee
