Abstract
Official abstract text for this publication.
There are provided for each column of pixels, a detecting unit which detects a voltage between a gate and a source of a drive transistor when a predetermined current is fed to the drive transistor and a unit which adds a data voltage to the voltage supplied by the detecting unit and supplies a sum to a data line.
First claim
Opening claim text (preview).
What is claimed is: 1. A display apparatus comprising: pixels arranged in a row direction and a column direction; a data line and a feedback line provided for each column of the pixels; and a column control circuit connected to the data line and feedback line, wherein a light emitting device and a drive circuit which drives the light emitting device are provided for each of the pixels, the drive circuit has a drive transistor which controls current to be fed to the light e…
