Patent number: 7015997Abstract: A high reflection and transmission transflective liquid crystal display (TLCD) that requires only a single cell gap. Instead of reducing the cell gap of the R sub-pixel region, the invention reduces the birefringence change ?n of reflective pixels (R) so that the total retardation change ?nd of R is equal to that of the transmissive pixels (T). This is realized by a partial switching of the pixels of approximately 45 degrees which occurs in the reflective pixel (R) region of the single cell gap by applying fringing fields, generated by a discontinuous electrode, to the molecules in the reflective pixel (R) region of the cell gap.Type: GrantFiled: April 29, 2003Date of Patent: March 21, 2006Assignees: University of Central Florida Research Foundation, Inc., Toppoly Optoelectronics Corp.Inventors: Wing Kit Choi, Shin-Tson Wu
