Liquid crystal display having a wide viewing characteristic and capable of fast driving
View Patent ↗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 n th gate line when the m th (m≧n+2) gate line is turned on.
1. 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 sub-pixel electrode and a second sub-pixel electrode corresponding to an n th main gate line and an i th data line;
a first switching element to selectively connect the first sub-pixel electrode with the i th data line;
a second switching element to selectively connect the second sub-pixel electrode with the i th data line;
an auxiliary gate line disposed between two neighboring main gate lines; and
a voltage varying element to vary at least one of a voltage of the first sub-pixel electrode and a voltage of the second sub-pixel electrode in response to a gate signal transmitted through the auxiliary gate line,
wherein the auxiliary gate line corresponding to the n th main gate line among the plurality of the main gate lines is connected with the m th (m≧n+2) main gate line and extends in a same direction as the n th main gate line in a lengthwise manner.
2. The liquid crystal display of claim 1 , further comprising a third switching element to control an operation of the voltage varying element in response to the gate signal from the auxiliary gate line.
3. The liquid crystal display of claim 1 , wherein the voltage varying element comprises at least one capacitor comprising two or more electrodes and one or more insulating layers.
4. The liquid crystal display of claim 1 , further comprising a connecting bridge connecting the auxiliary gate line corresponding to the n th main gate line with the m th main gate line.
5. The liquid crystal display of claim 4 , wherein the connecting bridge is disposed in a non-display area, the connecting bridge comprising the same material and being on the same layer as the data lines or the first sub-pixel electrode or the second sub-pixel electrode.
6. The liquid crystal display of claim 1 , wherein the auxiliary gate line is connected to a single row of pixels.
7. The liquid crystal display of claim 1 , wherein a single row of pixels is disposed between the two neighboring main gate lines.
8. The liquid crystal display of claim 1 , wherein the auxiliary gate line is connected to a plurality of switching elements, and none of the switching elements connected to the auxiliary gate line is connected to any data line of the plurality of data lines.
