Patent ID: 8063857

Claim:
An image display apparatus, comprising: a display unit having a plurality of pixels with light emitting elements formed in a matrix; a display signal driving circuit that drives a signal line and a display signal voltage for inputting a display signal voltage to a pixel region; a control line for inputting a control signal to the pixel region; a control signal driving circuit for driving the control signal; and a field effect transistor for driving the light emitting elements on the basis of a display signal that is inputted to the pixels through the signal line, wherein the control signal driving circuit changes the drive control signal according to a voltage or a signal related to a plurality of luminance modes, and wherein the field effect transistor has a source electrode, a gate electrode and a drain electrode, the source electrode being connected to a supply potential, the gate electrode being connected with a first switch for connecting the gate electrode and the drain electrode to each other and a capacitor, and the drain electrode being connected with a third switch for controlling the supply of a current on the basis of the image data signal to the light emitting element, wherein the light emitting element has an anode and a cathode, and the anode is connected with the third switch and a second switch for applying a given voltage from the external, and wherein, in any of the plurality of luminance modes, a precharge operation is conducted by turning on the second switch during a period in which the first and the third switches turn on at the same time.
