Abstract:
1. A method of improving a transflective liquid crystal display (TLCD) comprising the steps of: providing a liquid crystal area structure having a transmissive portion and a reflective portion in the liquid crystal area of the transflective LCD comprising the steps of: fabricating a serpentine wall on a transparent substrate; sealing the serpentine wall to the substrate to form independent transmissive and reflective regions having an equal cell gap; filling the transmissive portion with a first liquid crystal material; filling the reflective portion with a second liquid crystal material, a birefringence of the second liquid crystal material being one-half a birefringence of the first liquid crystal material in the transmissive portion; and passing backlight and ambient light through the TLCD to achieve identical transmittance and reflectance displaying high quality images.
