Abstract

Transflective twisted nematic (TN) liquid crystal displays(LCDs) having enhanced transmission efficiencies. Due to the use of circularly polarized light, the novel TN transflective LCD uses a new operation mode between the conventional First and Second Minimums, which alters the retardation value of the reflection and the transmission portions, where the retardation values each include a cell gap spacing. This results in the cell gap spacing in the transmission portion of the transflective LCD to be approximately triple the cell gap spacing in the reflection portion of the transflective LCD whereby the transmission efficiency increases to approximately 90 percent.
