Abstract
A display device includes a color plate and a shutter device. The color plate includes color pixels configured to emit color lights included in a first color image. The shutter device is disposed on the color plate to receive the color lights of the first color image and includes shutter pixels adjusting the color lights of the first color image to output a second color image. The shutter device contains a first number of the shutter pixels in a unit area and the color plate contains a second number of the color pixels in the unit area, the first number being greater than the second number.
Claims20
A display device, comprising:
- a color plate comprising color pixels configured to emit color lights comprised in a first color image;
- and
- a shutter device disposed on the color plate to receive the color lights of the first color image and comprising shutter pixels, wherein the shutter device is configured to adjust the color lights of the first color image to output a second color image,
- wherein the shutter device contains a first number of the shutter pixels in a unit area and the color plate contains a second number of the color pixels in the unit area, the first number being greater than the second number.
A method of generating a color image, the method comprising steps of:
- receiving input image data;
- processing the input image data to generate first image data including color information of the input image data and to generate second image data including luminance information of the input image data, the first image data having a first resolution and the second image data having a second resolution higher than the first resolution;
- generating color lights to provide a first color image based on the first image data;
- and
- adjusting luminance of the color lights of the first color image to output a second color image based on the second image data.
