Abstract
A display apparatus includes a plurality of pixels. Each pixel includes a first sub-pixel that is charged with a data signal corresponding to an input gray-scale, in response to a gate signal, and a second sub-pixel that is charged with the data signal in response to the gate signal. A boost capacitor is disposed between the first and second sub-pixels. The boost capacitor increases the voltage of the signal charged in the first sub-pixel and decreases the voltage of the signal charged in the second sub-pixel. Each pixel further includes an initializing device to initialize a first electrode of the boost capacitor and a switching device to change an electric potential of the first electrode of the boost capacitor.
Claims9
A display apparatus comprising:
- gate lines configured to receive a gate signal;
- data lines configured to receive a data signal;
- and
- pixels, each pixel comprising:
- a pixel electrode comprising a first sub-pixel electrode and a second sub-pixel electrode;
- a first switching device connected to at least one of the gate lines, at least one of the data lines, and the first sub-pixel electrode;
- a second switching device connected to the at least one of the gate lines, the at least one of the data lines, and the second sub-pixel electrode;
- a boost capacitor connected to the first sub-pixel electrode;
- a third switching device connected to the at least one of the gate lines, the boost capacitor, and a storage voltage line;
- and
- a fourth switching device comprising a gate electrode in a floating state and not connected to the gate lines, the fourth switching device connected to the second sub-pixel electrode and the boost capacitor,
- wherein a driving current of the first and third switching devices is greater than a leakage current of the fourth switching device.
