Abstract
Official abstract text for this publication.
An EL display panel includes light emitting pixels disposed in a matrix and a driving circuit for driving the pixels. The driving circuit drives the pixels such that a threshold value correction operation is carried out commonly (simultaneously) for a group of multiple pixels, which are connected to a same signal line, and such that an operation of writing a signal potential corresponding to a gradation value is executed individually (time-sequentially) for the pixels in the group. The driving circuit applies a reset potential to the pixels in the group before executing the signal writing operation. The reset potential is lower than a reference potential that is used for the threshold value correction operation.
First claim
Opening claim text (preview).
What is claimed is: 1. An electro luminescence display device having a pixel array section, the pixel array section comprising a driving circuit and a plurality of pixels disposed in a matrix, wherein the driving circuit is configured to drive the plurality of pixels such that: a reset potential lower than a reference potential is supplied to each pixel of a group simultaneously before any corresponding signal potential is written into a pixel of the group for a given frame, t…
