Abstract
Disclosed is a display apparatus including a display panel including a plurality of light-emitting areas and a non-light-emitting area between the plurality of light-emitting areas, and a transmittance control film including a first area having first visible light transmittance, wherein the first area is disposed on the display panel and overlaps at least a portion of the non-light-emitting area, and a plurality of the second areas having second visible light transmittance higher than the first visible light transmittance, wherein the plurality of the second areas overlap the plurality of light-emitting areas.
Claims16
A display apparatus comprising:
- a display panel including a plurality of light-emitting areas and a non-light-emitting area between the plurality of light-emitting areas;
- and
- a transmittance control film disposed on the display panel and including a first area having first visible light transmittance, wherein the first area overlaps at least a portion of the non-light-emitting area, and a plurality of second areas having second visible light transmittance higher than the first visible light transmittance, wherein the plurality of the second areas overlap the plurality of light-emitting areas,
- wherein the transmittance control film contains a photochromic dye irreversibly discolored by UV irradiation and a photoacid generator, and
- wherein a main absorption peak of the photoacid generator is equal to or lower than 400 nm, and is lower than a main absorption peak of the photochromic dye by 150 nm or more.
A display apparatus comprising:
- a display panel including a plurality of light-emitting areas and a non-light-emitting area between the plurality of light-emitting areas;
- and
- a transmittance control film disposed on the display panel and including an opaque area and at least overlapping wirings and thin-film transistors disposed in the non-light-emitting area and a plurality of transparent areas overlapping the plurality of light-emitting areas,
- wherein the transmittance control film contains a photochromic dye irreversibly discolored by UV irradiation and a photoacid generator, and
- wherein a main absorption peak of the photoacid generator is equal to or lower than 400 nm, and is lower than a main absorption peak of the photochromic dye by 150 nm or more.
