Abstract

A display panel and a display device are provided. The display panel includes a display component layer and a first anti-reflective film arranged on the display component layer. The display component layer includes a first polarizer, a first substrate arranged on the first polarizer, a second substrate arranged on the first substrate and a second polarizer arranged on the second substrate. The anti-reflective film on the second polarizer may reduce reflected light energy while increasing transmitted light energy.

First claim

What is claimed is:

1. A display panel, comprising:
a display component layer, comprising:
a first polarizer;
a first substrate arranged on the first polarizer;
a second substrate arranged on the first substrate; and
a second polarizer arranged on the second substrate;

a first anti-reflective film arranged on the second polarizer;
a touch-control component arranged on the first anti-reflective film; and
a second anti-reflective film arranged on the touch-control component away from the first anti-reflective film.

2. The display panel of claim 1 , further comprising:
a light guide plate provided between the touch-control component and the first anti-reflective film, wherein the light guide plate is arranged on the first anti-reflective film; and
a light emitting component arranged at a lateral side of the light guide plate.

3. The display panel of claim 2 , further comprising:
an optical adhesive layer arranged on the light guide plate,
wherein the touch-control component is arranged on the optical adhesive layer.

4. The display panel of claim 2 , further comprising:
a circuit board connected to a bottom surface of the light guide plate and a bottom surface of the light emitting component.

5. The display panel of claim 1 , wherein
the touch-control component comprises a sensor layer and a cover arranged on the sensor layer.

6. The display panel of claim 1 , further comprising:
a light emitting component arranged at a lateral side of the first substrate.

7. The display panel of claim 1 , wherein a thickness of the first anti-reflective film is equal to a quarter of wavelength of light in the first anti-reflective film; and a thickness of the second anti-reflective film is equal to a quarter of wavelength of light in the second anti-reflective film.

8. A display device, comprising:
a display component layer, comprising a first polarizer, a first substrate, a second substrate and a second polarizer successively stacked;
a first anti-reflective film stacked on the second polarize;
a touch-control component arranged on the first anti-reflective film; and
a second anti-reflective film arranged on the touch-control component away from the first anti-reflective film.

9. The display device of claim 8 , further comprising:
a light guide plate provided between the touch-control component and the first anti-reflective film, wherein the light guide plate is arranged on the first anti-reflective film; and
a light emitting component arranged at a lateral side of the light guide plate.

10. The display device of claim 9 , further comprising:
an optical adhesive layer arranged on the light guide plate;
wherein the touch-control component is arranged on the optical adhesive layer.

11. The display device of claim 9 , further comprising:
a circuit board connected to a bottom surface of the light guide plate and a bottom surface of the light emitting component.

12. The display device of claim 8 , wherein
the touch-control component comprises a sensor layer and a cover arranged on the sensor layer.

13. The display device of claim 8 , further comprising:
a flexible circuit board connected to a top surface of the first substrate.

14. The display device of claim 8 , wherein a thickness of the first anti-reflective film is equal to a quarter of wavelength of light in the first anti-reflective film; and a thickness of the second anti-reflective film is equal to a quarter of wavelength of light in the second anti-reflective film.

15. A mobile terminal, comprising:
a display component layer, comprising a first polarizer, a first substrate, a second substrate and a second polarizer successively stacked;
a first anti-reflective film stacked on the second polarizer;
a touch-control component stacked with the first anti-reflective film; and
a second anti-reflective film arranged on the touch-control component away from the first anti-reflective film.

16. The mobile terminal of claim 15 , wherein a thickness of the first anti-reflective film is equal to a quarter of wavelength of light in the first anti-reflective film; and a thickness of the second anti-reflective film is equal to a quarter of wavelength of light in the second anti-reflective film.
