TRANSFLECTIVE LIQUID CRYSTAL DISPLAY WITH PARTIAL SWITCHING

摘要

A high reflection and transmission transflective liquid crystal display (TLCD) that requires only a single cell gap (40). Instead of reducing the cell gap of the reflective (R) sub-pixel region, the invention reduces the birefringence change Deltad of reflective pixels (R) (42) so that the total retardation change Deltad 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 (42) of the single cell gap (40) by applying fringing fields, generated by a discontinuous electrode, to the molecules (44) in the reflective pixel(R) region (42) of the cell gap (40).
