Title:
IMAGE DISPLAY DEVICE AND METHOD FOR DRIVING SAME
Document Type and Number:
WIPO Patent Application WO/2010/137268
Kind Code:
A1
Abstract:
Provided is an image display device in which a period is ensured that can correct the threshold voltage of a driving transistor at a high accuracy, and also provided is a method for driving the image display device. The image display device has a plurality of light-emitting pixels arranged in a matrix and each light-emitting pixel comprises: a driving transistor for converting a signal voltage for determining an emission brightness to a driving current; a light-emitting element emitting light as a result of the driving current flowing therethrough; and a threshold voltage detection unit for detecting the threshold voltage of the driving transistor by applying a reference voltage. When a plurality of light-emitting pixel rows are formed as one driving block, the light-emitting pixels constitute two or more driving blocks. The image display device controls, during a predetermined period, each of the supplies of the reference voltage and power supply voltage to the entire light-emitting pixels belonging to the same driving block at the same timing and controls the supplies of the reference voltage and the power supply voltage between the different driving blocks at a different timing.
