Abstract

The embodiments of the present disclosure provide a display and a fabricating method thereof, and a fabricating method of a photosensitive film. The display comprises: a display screen for displaying a picture, and a photosensitive film disposed on a light emergent surface of the display screen, wherein the photosensitive film is configured to automatically adjust corresponding transmittance according to a gray level brightness of the picture displayed by the display screen, and the transmittance of the photosensitive film increases with the increase of the gray level brightness of the picture displayed by the display screen. The display provided by the embodiment of the present disclosure can increase the contrast ratio without changing the existing design, thereby improving the display effect of the display.

Claims

1. A display, comprising:

a display screen for displaying a picture; and

a photosensitive film disposed on a light emergent surface of the display screen, the photosensitive film configured to automatically adjust its corresponding transmittance according to a gray level brightness of the picture displayed by the display screen, with the transmittance of the photosensitive film increasing with an increase of the gray level brightness of the picture displayed by the display screen, the photosensitive film comprising a small organic molecular material including rigid and flexible groups, and transmittance of the small organic molecular material increasing with an increase of the gray level brightness of the picture displayed by the display screen under the effect of a photocatalyst.

2. The display according to claim 1, wherein a gray level brightness of a picture displayed by the display is a product of the gray level brightness of the picture displayed by the display screen and the adjusted transmittance of the photosensitive film.

3. The display according to claim 2, wherein the brightness of the picture displayed by the display is obtained from the following equation:

4. The display according to claim 1, wherein the small organic molecular material comprises a liquid crystal material.

5. The display according to claim 1, wherein a thickness of the photosensitive film is not more than 100 um.

6. The display according to claim 1, wherein the photosensitive film is attached to the light emergent surface of the display screen through an adhesive tape or a bonding agent.

7. The display according to claim 1, further comprising a semi-transmission and semi-reflection mirror fixed on the photosensitive film.

8. The display according to claim 7, wherein the semi-transmission and semi-reflection mirror is fixed on the photosensitive film through a bonding agent or a framework.

9. The display according to claim 1, wherein the display is an on-board rearview mirror display or a clock display.

10. A method of fabricating a photosensitive film for a display, the display including a display screen for displaying a picture, and the photosensitive film disposed on a light emergent surface of the display screen, the photosensitive film configured to automatically adjust its corresponding transmittance according to a gray level brightness of the picture displayed by the display screen, with the transmittance of the photosensitive film increasing with an increase of the gray level brightness of the picture displayed by the display screen, the method comprising:

forming the photosensitive film with a small organic molecular material including rigid and flexible groups, wherein a transmittance of the small organic molecular material increases with an increase of the gray level brightness of the picture displayed by the display screen of the display under the effect of a photocatalyst.

11. The fabricating method according to claim 10, wherein relations among the transmittance of the photosensitive film, a gray level brightness of a picture displayed by the display, and the gray level brightness of the picture displayed by the display screen, are given by the following equation:

12. The fabricating method according to claim 10, wherein the small organic molecular material comprises a liquid crystal material.

13. The fabricating method according to claim 10, wherein a thickness of the photosensitive film is not more than 100 um.

14. A method of fabricating a display, the display comprising a display screen for displaying a picture, and a photosensitive film disposed on a light emergent surface of the display screen, the photosensitive film configured to automatically adjust its corresponding transmittance according to a gray level brightness of the picture displayed by the display screen, with the transmittance of the photosensitive film increasing with an increase of the gray level brightness of the picture displayed by the display screen, the photosensitive film comprising a small organic molecular material including rigid and flexible groups, and transmittance of the small organic molecular material increasing with an increase of the gray level brightness of the picture displayed by the display screen under the effect of a photocatalyst, the method comprising:

attaching the photosensitive film to the light emergent surface of the display screen using an adhesive tape or a bonding agent.

15. The method of fabricating the display according to claim 14, further comprising:

fixing a semi-transmission and semi-reflection mirror on the photosensitive film through a bonding agent or a framework.

16. The method of fabricating the display according to claim 14, wherein a gray level brightness of a picture displayed by the display is a product of the gray level brightness of the picture displayed by the display screen and the adjusted transmittance of the photosensitive film.

17. The method of fabricating the display according to claim 16, wherein the brightness of the picture displayed by the display is obtained from the following equation:

18. The method of fabricating the display according to claim 14, wherein the photosensitive film comprises a liquid crystal material.

19. The method of fabricating the display according to claim 14, wherein a thickness of the photosensitive film is not more than 100 um.
