Abstract
A charge sharing style wide viewing liquid crystal display to which fast driving pre-charging technology may be applied to is disclosed. A charge sharing style wide viewing liquid crystal display is provided such that charge sharing is carried out between a liquid crystal capacitor and a charge sharing capacitor that correspond to the nth gate line when the mth (m≧n+2) gate line is turned on.
Claims11
A liquid crystal display, comprising:
- a substrate;
- a plurality of main gate lines disposed on the substrate;
- a plurality of data lines insulated from and crossing at least one main gate line;
- a first liquid crystal capacitor and a second liquid crystal capacitor corresponding to an nth main gate line and an ith data line;
- a first switching element to selectively connect the first liquid crystal capacitor with the ith data line;
- a second switching element to selectively connect the second liquid crystal capacitor with the ith data line;
- and
- a voltage varying element to vary at least one of a terminal voltage of the first liquid crystal capacitor and a terminal voltage of the second liquid crystal capacitor in response to a gate signal of the mth (m≧n+2) main gate line.
