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.
A display device receiving a video signal including grayscale data, and displaying images according to the input video signal, comprising:
A method setting a gamma value for a display device, comprising the steps of:

This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C §119 from an application entitled DISPLAY DEVICE AND GAMMA SETTING METHOD FOR THE SAME earlier filed in the Korean Industrial Property Office on May 4, 2010, and there duly assigned Serial No. 10-2010-0042116 by that Office.
1. Field of the Invention
The present invention relates to a display device and a gamma setting method for the display device. More particularly, the present invention relates to a display device and a gamma setting method for the display device capable of ensuring display quality of a display device when considering influence of external light.
A more complete appreciation of the present invention, and many of the attendant advantages thereof, will become readily apparent as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings in which like reference symbols indicate the same or similar components, wherein:
FIG. 1 is a block diagram of an organic light emitting diode (OLED) display according to an exemplary embodiment of the present invention;
FIG. 2 is a circuit diagram of a pixel of FIG. 1;
In the following detailed description, only certain exemplary embodiments of the present invention have been shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.
Constituent elements having the same structures throughout the embodiments are denoted by the same reference numerals and are described in a first exemplary embodiment. In the other exemplary embodiments, only constituent elements other than the same constituent elements are described.
To clearly describe the exemplary embodiments of the present invention, parts not related to the description are omitted, and like reference numerals designate like constituent elements throughout the specification.
