Abstract
A method of repairing a display device, in which the display device includes a defective pixel area including a defective wavelength conversion patter, the method including removing the defective wavelength conversion pattern of the defective pixel area, injecting ink including a wavelength conversion material into the defective pixel area, and curing the ink injected into the defective pixel area.
Claims20
A method of repairing a display device, in which the display device comprises,
- a color filter, and
- a wavelength conversion layer on the color filter, configured to convert a wavelength of light incident on the wavelength conversion layer, and comprising a defective wavelength conversion pattern corresponding to a defective pixel area,
- the method comprising:
- removing the defective wavelength conversion pattern of the defective pixel area and without removing the color filter;
- injecting ink comprising a wavelength conversion material into the defective pixel area where the defective wavelength conversion pattern was removed;
- and
- curing the ink injected into the defective pixel area.
A method of repairing a display device, in which the display device comprises,
- a color filter, and
- a wavelength conversion layer on the color filter, configured to convert a wavelength of light incident on the wavelength conversion layer, and comprising a mixed wavelength conversion pattern configured to convert a wavelength of light incident on the mixed wavelength conversion pattern,
- the method comprising:
- removing the mixed wavelength conversion pattern without removing the color filter;
- and
- forming a repair pattern in a groove formed by the removing of the mixed wavelength conversion pattern.
A display device comprising a pixel which comprises a first sub-pixel configured to display a first color and a second sub-pixel configured to display a second color, the display device comprising:
- a color conversion substrate, the color conversion substrate comprises:
- a first substrate;
- a color filter on a surface of the first substrate;
- a color control layer on a surface of the color filter and comprising a wavelength conversion layer configured to convert a wavelength of light incident on the wavelength conversion layer, the wavelength conversion layer comprising a first wavelength conversion pattern belonging to the first sub-pixel and a repair pattern belonging to the second sub-pixel;
- and
- a mixed wavelength conversion layer between the first substrate and the repair pattern and configured to convert a wavelength of light incident on the mixed wavelength conversion layer.
