Abstract
An optical module and a tiled display device. The optical module comprises: a diffusion plate (10b); a color conversion layer (20b) provided on one side of the diffusion plate (10b); and a wavelength selective transmission layer (30) provided between the diffusion plate (10b) and the color conversion layer (20b), wherein the wavelength selective transmission layer (30) is configured to transmit light of a specific color and prevent the transmission of light of colors other than the light of the specific color.
Claims13
An optical module, comprising:
- a diffusion plate;
- a color conversion layer stacked on a side of the diffusion plate;
- a wavelength-selective transmission layer stacked between the diffusion plate and the color conversion layer, wherein the wavelength-selective transmission layer is configured to transmit light of a specific color and prevent transmission of light of other colors except the light of the specific color;
- wherein a side surface of the diffusion plate, a side surface of the wavelength-selective transmission layer, and a side surface of the color conversion layer are flush;
- and
- a frame sealing glue layer, wherein the frame sealing glue layer covers the side surface of the diffusion plate, the side surface of the wavelength-selective transmission layer, and the side surface of the color conversion layer;
- the frame sealing glue layer is configured to prevent blue light overflow at a display edge due to an edge failure of the color conversion layer;
- a cross-sectional shape of the frame sealing glue layer is arc-shaped, a maximum thickness of the frame sealing glue layer covering the color conversion layer is less than a maximum thickness of the frame sealing glue layer covering the wavelength-selective transmission layer, and the maximum thickness of the frame sealing glue layer covering the wavelength-selective transmission layer is less than a maximum thickness of the frame sealing glue layer covering the diffusion plate;
- wherein the wavelength-selective transmission layer is a color filter layer, and a material of the wavelength-selective transmission layer comprises a dispersant and a blue pigment.
