Abstract
A field sequential LCD capable of applying a reset signal having a higher voltage level than a data signal to a liquid crystal so as to represent a predetermined gradation is provided. The field sequential LCD includes an LCD panel having a plurality of pixels for displaying an image, a gate driver supplying a scan signal to the LCD panel through a scan line, a source driver generating a data signal, and a selection circuit coupled between the source driver and the LCD panel. The selection circuit receives the data signal and a reset signal and, in response to a selection signal, supplies the reset signal to the data line during a reset period and supplies the data signal having a lower voltage level than the reset signal to the data line during a data programming period.
Claims13
A field sequential liquid crystal display (LCD) comprising:
- an LCD panel having a plurality of pixels for displaying an image;
- a gate driver for supplying a scan signal to the LCD panel through a scan line;
- a source driver for generating a data signal;
- and
- a selection circuit coupled between the source driver and the LCD panel for selectively supplying the data signal and a reset signal having a higher voltage level than the data signal to each of the plurality of pixels.
A field sequential liquid crystal display (LCD) comprising:
- an LCD panel having at least one pixel for displaying an image, the pixel formed in a region where a scan line intersects a data line, the pixel having a liquid crystal portion;
- a gate driver for supplying a scan signal to the pixel through the scan line;
- a source driver for generating a data signal;
- and
- a selection circuit having a plurality of switching devices coupled between the source driver and the LCD panel for supplying the data signal or a reset signal having a higher voltage level than the data signal to the liquid crystal through the data line in response to a selection signal.
