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.

Claims (32)

1. 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.

2. The backlight module of claim 1 , wherein the anti-blue light substance comprises at least one of lutein and zeaxanthin.

3. The backlight module of claim 1 , wherein a material of the light-penetration layer comprises a light-penetration structure, and the light-penetration structure encapsulates the anti-blue light substance.

4. The backlight module of claim 3 , wherein a material of the light-penetration structure comprises a heat-curing material or a light-curing material.

5. The backlight module of claim 1 , further comprising an adhesive layer, wherein the adhesive layer is adhered between the light-penetration layer and the light incident surface.

6. The backlight module of claim 5 , wherein a material of the adhesive layer comprises an optical clear adhesive or an optical clear resin.

7. The backlight module of claim 5 , wherein a material of the adhesive layer comprises a heat-curing material or a light-curing material.

8. The back light module of claim 1 , wherein the light incident surface is a rough surface.

9. The backlight module of claim 1 , wherein the light-penetration layer is an anti-blue light layer.

10. The backlight module of claim 1 , wherein the wavelength range is between 380 nm and 495 nm.

11. 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.

12. The display of claim 11 , wherein the anti-blue light substance comprises at least one of lutein and zeaxanthin.

13. The display of claim 11 , wherein a material of the light-penetration layer comprises a light-penetration structure, and the light-penetration structure encapsulates the anti-blue light substance.

14. The display of claim 13 , wherein a material of the light-penetration structure comprises a heat-curing material or a light-curing material.

15. The display of claim 11 , wherein the backlight module comprises an adhesive layer, and the adhesive layer is adhered between the light-penetration layer and the light incident surface.

16. The display of claim 15 , wherein a material of the adhesive layer comprises an optical clear adhesive or an optical clear resin.

17. The display of claim 15 , wherein a material of the adhesive layer comprises a heat-curing material or a light-curing material.

18. The display of claim 11 , wherein the light incident surface is a rough surface.

19. The display of claim 11 , wherein the light-penetration layer is an anti-blue light layer.

20. The display of claim 11 , wherein the wavelength range is between 380 nm and 495 nm.
