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.
Claims20
A display controller comprising:
- a circuitry configured to output a second image data, the second image data being generated by adding an edge component to an first image data;
- and
- wherein the edge component includes a minus direction component and a plus direction component, and
- the circuitry 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.
A self-luminescent display device comprising:
- a processing circuitry configured to output a second image data, the second image data being generated by adding an edge component to a first image data;
- and
- a display panel configured to display an image depending on the second image data,
- wherein the edge component includes a minus direction component and a plus direction component, and the processing circuitry is configured to set respective magnitudes of the minus direction component and the plus direction component based on specific conditions,
- wherein the display panel includes a plurality of pixel elements, each of the pixel elements including a drive transistor, a sampling transistor and a light emitting element driven by a current supply controlled by the drive transistor,
- wherein a power consumption amount of the display panel is dependent on an intensity of light emitted by the light emitting elements, and
- wherein the specific conditions are based on at least an average value of a plurality of values respectively corresponding to an intensity of light emitted by each of the light emitting elements within an area in the display panel, where the average value related to the power consumption amount of the display panel.
