Patent ID: 7471267

Claim:
An emission display comprising: a plurality of data lines extending in one direction, each said data line for transmitting a data current; a plurality of select signal lines crossing the data lines, each said select signal line for transmitting a first scan signal having an on level; a plurality of emit signal lines crossing the data lines, each said emit signal line for transmitting a second scan signal; a display panel including: a first switch on a pixel area defined by a corresponding said data line, a corresponding said select signal line, and a corresponding said emit signal line, for transmitting the data current from the corresponding said data line in response to the first scan signal from the corresponding said select signal line, a pixel circuit including a capacitor for charging a voltage corresponding to the data current from the first switch, an emission element, a transistor for supplying a current corresponding to the voltage charged in the capacitor to the emission element, and a second switch between the transistor and the emission element for supplying the current from the transistor to the emission element in response to a first level of the second scan signal from the corresponding said emit signal line; and a driver for supplying the first scan signal to the corresponding said select signal line, and supplying the second scan signal to the corresponding said emit signal line, wherein the select signal lines include first select signal lines and second select signal lines, wherein the corresponding said select signal line is one of the first select signal lines, wherein the driver is adapted to transmit the first scan signal having the on level to the corresponding said select signal line during a first field of a single frame, and to transmit the first scan signal having the on level to one of the second select signal lines during a second field of the single frame, and the driver is configured to transfer the second scan signal having a second level to the second switch to prevent the emission element from emitting during a non-emission period while the capacitor is being charged.
