Abstract
Official abstract text for this publication.
A display device receiving a video signal including grayscale data and displaying images according to the input video signal includes: a photosensor measuring illuminance of external light; a timing controller processing the data signal according to a target gamma value corresponding to the measured illuminance among a plurality of gamma values for a reference curved line representing a relationship of a lightness variation according to a change of grayscale data to be applied to the measured illuminance environment; a data driver applying the processed data signal to a plurality of pixels; and a scan driver applying a scan signal to the plurality of pixels for the data signal to be applied to the plurality of pixels. Accordingly, an image or a motion picture may be displayed with a desired grayscale without influence of external light, and the display quality may be obtained in an external light environment without increasing power consumption.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device receiving a video signal including grayscale data, and displaying images according to the input video signal, comprising: a photosensor measuring illuminance of external light; a timing controller connected to the photosensor, and receiving and processing a data signal according to a target gamma value corresponding to the measured illuminance among a plurality of gamma values for a reference curved line representing a relationship of a li…
