Field sequential liquid crystal display
A field sequential LCD includes a reset selector supplying a reset signal having a higher voltage level than a data signal to the liquid crystal. The reset selector selects the reset signal in response to a reset control signal, and supplies the selected reset signal to a data line.
1. A field sequential liquid crystal display (LCD) comprising:
an LCD panel having a pixel formed in a region in which a scan line intersects a data line to display an image;
a gate driver supplying a scan signal to the pixel through the scan line;
a source driver supplying a data signal having a first voltage level to the pixel through the data line; and
a reset selector having a transmission gate connected to the data line, and supplying a reset signal having a second voltage level that is higher than the first voltage level through the data line to the pixel during a reset period, wherein the transmission gate of the reset selector includes a PMOS transistor, wherein the number of transmission gates corresponds to the number of data lines, and wherein the PMOS transistor of the transmission gate includes:
a gate terminal to which a reset control signal is applied for turning the PMOS transistor on or off;
a first electrode to which the reset signal is applied; and
a second electrode connected to the data line, and supplying the reset signal from the first electrode to the pixel through the data line in response to the reset control signal.

a gate driver supplying a scan signal to the pixel through the scan line;
a source driver supplying a data signal having a first voltage level to the pixel through the data line; and
a reset selector having a transmission gate connected to the data line, and supplying a reset signal having a second voltage level that is higher than the first voltage level through the data line to the pixel during a reset period, wherein the transmission gate of the reset selector includes a PMOS transistor and an NMOS transistor connected to each other in parallel and the number of transmission gates corresponds to the number of data lines, and
wherein the transmission gate includes:
a gate terminal of the PMOS transistor that receives the reset control signal for turning the PMOS transistor on or off;
a gate terminal of the NMOS transistor that receives an inverted reset control signal for turning the NMOS transistor on or off;
a first electrode to which the reset signal is applied; and
a second electrode connected to the data line, and supplying the reset signal from the first electrode to the pixel through the data line in response to the reset control signal.
