Abstract
A backlight module including a back plate, a light guide plate, a light-penetration layer, and a light source is provided. The light guide plate is disposed on the back plate and has a light incident surface and a light-emitting surface. The light-penetration layer is disposed on the light incident surface and adapted to absorb a light in a wavelength range. The light source is disposed on the back plate and faces the light incident surface, wherein the light source is adapted to provide a light. After the light passes through the light-penetration layer, the light enters the light guide plate from the light incident surface and is emitted from the light-emitting surface. In addition, a display having the backlight module is also provided.
Claims20
A backlight module, comprising:
- a back plate;
- a light guide plate disposed on the back plate and having a light incident surface and a light-emitting surface;
- a light-penetration layer disposed on the light incident surface and adapted to absorb a blue light in a wavelength range without changing the wavelength range of the blue light;
- and
- a light source disposed on the back plate and facing the light incident surface, wherein the light source is adapted to provide a light, and after the light passes through the light-penetration layer, the light enters the light guide plate from the light incident surface and is emitted from the light-emitting surface,
- wherein the light-penetration layer comprises an anti-blue light substance.
A display, comprising:
- a display panel;
- and
- a backlight module, comprising:
- a back plate;
- a light guide plate disposed on the back plate and having a light incident surface and a light-emitting surface, wherein the light-emitting surface faces the display panel;
- a light-penetration layer disposed on the light incident surface and adapted to absorb a blue light in a wavelength range without changing the wavelength range of the blue light;
- and
- a light source disposed on the back plate and facing the light incident surface, wherein the light source is adapted to provide a light, and after the light passes through the light-penetration layer, the light enters the light guide plate from the light incident surface and is emitted from the light-emitting surface,
- wherein the light-penetration layer comprises an anti-blue light substance.
