Abstract
A display device includes: an extraction unit extracting an edge component of a display data signal; an adder unit adding an edge component to the display data signal; a signal generation unit generating a control signal in accordance with the display data signal and an output signal of the adder unit; a correction unit carrying out correction processing on the edge component in accordance with the control signal and outputting the corrected edge component to the adder unit; and a display unit carrying out a display operation in accordance with the output signal of the adder unit.
Claims19
A self-luminescent display device comprising:
- a processing unit configured to output a modified image data, the modified image data being generated by adding an edge component to a display data;
- and
- a display unit configured to display an image depending on the modified image data,
- wherein the edge component includes a minus direction component and a plus direction component, and
- the processing unit is configured to execute at least one of image processings selected from a group consisting of:
- (i) a first processing so as to set a magnitude of the minus direction component greater when a gradation level of the display data is high than a magnitude of the minus direction component when a gradation level of the display data is low;
- and
- (ii) a second processing so as to set a magnitude of the plus direction component smaller when a gradation level of the display data is high than a magnitude of the plus direction component when a gradation level of the display data is low.
