Abstract

Disclosed is an image display apparatus having, in every pixel, a light-emitting element such as an organic electro-luminescence (EL) element of which the brightness is controlled by a current. The image display apparatus includes transistors that form a current mirror in the pixel and using a pixel structure having two scan lines, so as to select pixels of at least two rows simultaneously, distribute the current applied to the data line to the pixel for recording display information and the adjacent pixel, and record the display information on the pixel of no more than one row among the selected pixels. This drastically increases the current for driving the data line and decreases the size of the transistors that form the current mirror in the pixel.

Claims6

Dependent claims

A light emitting device to be coupled to a date line and first and second control lines, comprising:

a light emitting element;
a data input for receiving a portion of a data current including brightness information on such data line, the light emitting element being responsive to said portion of the data current to adjust brightness of light emitted;
a first control input for receiving a first control signal over such first control line, said first control input being responsive to said first control signal to divert said portion of the data current from such data line through the data input;
and
a second control input for receiving a second control signal over such second control line, said second control input being responsive to enable said portion of the data current to control the brightness of light emitted by the light emitting element.
