Light emission display, display panel, and driving method thereof

摘要

A light emission display includes data lines, scan lines, and pixel circuits. A pixel circuit of the pixel circuits includes: a light emission element; a first transistor including a control electrode and first and second electrodes, the first transistor outputting a current corresponding to a voltage between the first electrode and the control electrode; a first switch coupled between the control electrode of the first transistor and the light emission element and for receiving a first control signal; a first capacitor coupled to the first transistor; a second capacitor coupled between a first power source and the first capacitor; a second switch for coupling the first capacitor and a second power source in response to a second control signal; and a third switch for applying a data voltage to the first capacitor in response to a select signal provided by one of the scan lines.
