Patent attributes
A single-gap transflective LCD panel having a voltage divider in each sub-pixel for reducing the voltage potential across part of the liquid crystal layer in the sub-pixel. In a normally-black LCD panel, the voltage divider is used to reduce the voltage potential across the liquid crystal layer in the reflection area. In a normally-white LCD panel, the voltage divider is used to reduce the voltage potential across the liquid crystal layer in the transmission area. The voltage divider comprises two poly-silicon resistor segments connected in series between a data line and a common line via one or more switching elements controlled by a gate line signal. With poly-silicon resistor segments being disposed in the reflection area below the reflective electrode, the optical quality of the upper electrode and the transmissive electrode is not affected by the voltage divider.
