Abstract
According to one aspect of the invention, a display panel, includes: a first layer; a light control member disposed on the first layer, the light control member including a light converting element to initiate a change in wavelength of a first light to be emitted from the first layer; and a filter disposed on the light control member, the filter including a photochromic compound having a conjugation bond reversibly elongatable by absorbable light in a wavelength region of the first light to allow selective transmission of light in a wavelength region of about 480 nm or longer.
Claims20
A display panel, comprising:
- a first layer;
- a light control member disposed on the first layer, the light control member comprising a light converting element to initiate a change in wavelength of a first light to be emitted from the first layer;
- and
- a filter disposed on the light control member, the filter comprising a photochromic compound having a conjugation bond reversibly elongatable by absorbable light in a wavelength region of the first light to allow selective transmission of light in a wavelength region of about 480 nm or longer.
A display panel, comprising:
- a first layer to emit a first light when activated;
- a light control member disposed on the first layer, the light control member comprising a first light controller to transmit the first light, a second light controller to convert the first light to a second light, and a third light controller to convert the first light to a third light, the second and third lights having wavelengths longer than that of the first light wavelength and different from each other;
- and
- a filter disposed on the light control member, the filter comprising a photochromic compound,
- wherein the photochromic compound comprises a conjugation bond reversibly elongatable when absorbing light in a wavelength region of the first light, and to selectively transmit light in a wavelength region of about 480 nm or longer.
A display panel, comprising:
- an emission element layer to emit a first light when activated;
- a light control member disposed on the emission element layer, the light control member comprising a first light controller to transmit the first light, a second light controller to convert the first light to a second light, and a third light controller to convert the first light to a third light, the second and third lights having wavelengths longer than that of the first light wavelength and different from each other;
- and
- a filter disposed on the light control member, the filter comprising a photochromic compound, wherein the photochromic compound comprises:
- a first photochromic compound having a first structure to transmit light in a whole visible wavelength range when deactivated, and having a second structure to block a blue light and to transmit a green light when activated;
- and
- a second photochromic compound having a third structure to transmit light in the whole visible wavelength range when deactivated and having a fourth structure to block the blue light and to transmit a red light when activated.
