Abstract
A display apparatus is provided. The display apparatus includes a display panel comprising a plurality of pixels, a panel driver configured to drive the display panel, a storage configured to store information regarding a color gamut of each of the plurality of pixels, and a processor configured to determine a target color gamut of each of the plurality of pixels so that a difference in color gamut from at least one adjacent pixel is equal to or less than a predetermined threshold value, and to drive the panel driver for each of the plurality of pixels to have a grayscale value based on the target color gamut.
Claims10
A display apparatus, comprising:
- an LED module comprising a plurality of LEDs;
- a driver configured to drive the LED module;
- and
- a processor configured to control the driver to cause a color gamut difference between a color gamut of an LED among the plurality of LEDs and a color gamut of at least one LED adjacent to the LED to be equal to or less than a predetermined threshold value, based on color gamut information for each LED among the plurality of LEDs and based on summing color gamut differences between the LED and a plurality of LEDs adjacent to the LED from among the plurality of LEDs.
A display apparatus, comprising:
- an LED module comprising a plurality of LEDs;
- a driver configured to drive the LED module;
- and
- a processor configured to control the driver to cause a color gamut difference between a color gamut of an LED among the plurality of LEDs and a color gamut of at least one LED adjacent to the LED to be equal to or less than a predetermined threshold value, based on color gamut information for each LED among the plurality of LEDs;
- wherein the processor is configured to determine a color coordinate of the LED that enables a color coordinate difference between a color coordinate corresponding to a maximum grayscale value of the LED and a color coordinate corresponding to a maximum grayscale value of at least one adjacent LED to be equal to or less than the predetermined threshold value.
A calibration method, comprising:
- determining a color gamut difference between a color gamut of an LED among a plurality of LEDs and a color gamut of at least one LED adjacent to the LED based on information of a color gamut of each of the plurality of LEDs;
- obtain a value by summing color gamut differences between the LED and LEDs adjacent to the LED from among the plurality of LEDs, and
- driving an LED module comprising the plurality of LEDs based on the determined color gamut difference and the obtained value,
- wherein the determined color gamut difference is equal to or less than a predetermined threshold value.
