Abstract

Disclosed are a display screen film and a preparation method therefor, and an energy saving method. The display screen film comprises an oriented carbon nanotube layer and a quartz glass layer, wherein the oriented carbon nanotube layer is located above the quartz glass layer, comprises an oriented growth carbon nanotube, and is configured to refract all incident light through the oriented growth carbon nanotube; the quartz glass layer is used for the carbon nanotube layer to grow orientately thereon, and is also used for absorbing the incident light so as to enable all the incident light to reach the oriented carbon nanotube layer.

First claim

What is claimed is:

1 . A display screen film, comprising: a quartz glass layer and an orientated carbon nanotube layer,
wherein the orientated carbon nanotube layer is located on the quartz glass layer, comprises orientated grown carbon nanotubes and is configured to refract all incident light through the orientated grown carbon nanotubes; and wherein the quartz glass layer is configured to enable the orientated carbon nanotube layer to grow on it, and is configured to absorb incident light and enable all the incident light to reach the orientated carbon nanotube layer.

2 . A preparation method for a display screen film, comprising:
growing an orientated carbon nanotube layer on a quartz glass layer; absorbing, by the quartz glass layer, incident light, and enabling all the incident light to reach the orientated carbon nanotube layer; and refracting, by the orientated carbon nanotube layer, all the incident light.

3 . The method according to claim 2 , wherein the orientated carbon nanotube layer is grown on the quartz glass layer using hydrogen-free chemical vapour deposition.

4 . The method according to claim 2 , wherein carbon nanotubes of the orientated carbon nanotube layer have orientated growth directions of 90°±15°.

5 . The method according to claim 2 , wherein growing the orientated carbon nanotube layer on the quartz glass layer is: vertically growing, on the quartz glass layer, carbon nanotubes for refracting all incident light.

6 . The method according to claim 2 , wherein gaps between carbon nanotubes on the oriented carbon nanotube layer have a size in the range of 400 nm to 700 nm.

7 . The method according to claim 2 , wherein carbon nanotubes on the oriented nanotube layer have a diameter in the range of 20 nm to 80 nm.

8 . An energy saving method using a display screen film, comprising:
growing an orientated carbon nanotube layer on a quartz glass layer; forming the quartz glass layer having the orientated carbon nanotube layer grown thereon into the display screen film, and attaching the display screen film onto the surface of a display screen; absorbing, by the quartz glass layer, incident light from the surface of the display screen and enabling all the incident light to reach the orientated carbon nanotube layer; and refracting, by the orientated carbon nanotube layer, all the incident light to enable the light to emit out vertically after passing through the display screen film.

9 . The method according to claim 8 , wherein the orientated carbon nanotube layer is grown on the quartz glass layer using hydrogen-free chemical vapour deposition.

10 . The method according to claim 8 , wherein growing the orientated carbon nanotube layer on the quartz glass layer is: vertically growing, on the quartz glass layer, carbon nanotubes for refracting all the incident light.

11 . The method according to claim 3 , wherein growing the orientated carbon nanotube layer on the quartz glass layer is: vertically growing, on the quartz glass layer, carbon nanotubes for refracting all incident light.

12 . The method according to claim 3 , wherein gaps between carbon nanotubes on the oriented carbon nanotube layer have a size in the range of 400 nm to 700 nm.

13 . The method according to claim 3 , wherein carbon nanotubes on the oriented nanotube layer have a diameter in the range of 20 nm to 80 nm.

14 . The method according to claim 9 , wherein growing the orientated carbon nanotube layer on the quartz glass layer is: vertically growing, on the quartz glass layer, carbon nanotubes for refracting all the incident light.
