Abstract
Official abstract text for this publication.
A controller outputs a row rewriting control signal and a column rewriting control signal as well as a data signal. The row rewriting control signal is a signal selecting whether a selection signal is supplied to a first scan line, and the column rewriting control signal is a signal selecting whether a selection signal and a data signal are supplied to the second scan line and the signal line, respectively. The row rewriting control signal and the column rewriting control signal are thus output from the controller, which makes it possible to select whether a data signal is rewritten in each of a plurality of pixels arranged in matrix. Consequently, even in the case of displaying an image having a specific area, the display of which is often changed, a high-quality image can be displayed with reduced power consumption.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display device comprising: a controller configured to output a row rewriting control signal indicating whether there is a difference between successive two frames in at least one of a first pixel to an n-th pixel (n is a natural number of two or more) arranged in the same row, and a column rewriting control signal indicating whether there is a difference between the successive two frames in a k-th pixel (k is a natural number more than or equal to on…
