Abstract

A display apparatus providing light therapy includes a display panel configured to display an image to a display region based on input image data, and a lens part disposed on the display panel, the lens part configured to focus the image displayed by the display panel toward a first region in a therapy mode, in which the first region is smaller than the display region, and the first region may correspond to a position of a user'"'"'s face.

Claims

1. A display apparatus providing light therapy comprising:

a display panel configured to display an image to a display region based on input image data; and

a lens part disposed on the display panel, the lens part configured to focus the image displayed by the display panel toward a first region in a therapy mode, wherein the first region is smaller than the display region.

2. The display apparatus of claim 1, wherein the display panel uses a first color coordinate in a display mode and a second color coordinate in the therapy mode.

3. The display apparatus of claim 2, wherein a wavelength of blue light is about 415 nm in the second color coordinate, a wavelength of green light is about 550 nm in the second color coordinate and a wavelength of red light is about 633 nm in the second color coordinate.

4. The display apparatus of claim 1, further comprising a display panel driver driving the display panel and a lens driver driving the lens part,

wherein the display panel driver includes a therapy controlling part configured to output first image data in a display mode and second image data in the therapy mode, the therapy controlling part configured to output a lens driving signal to the lens driver in the therapy mode.

5. The display apparatus of claim 1, further comprising a user detecting part configured to determine a position of an object relative to the lens part.

6. The display apparatus of claim 5, wherein

the lens part adjusts a position of the first region to correspond to the position of the object.

7. The display apparatus of claim 5, wherein the user detecting part is configured to determine a distance of an object from the lens part, and

a focal length of the lens part is adjusted based on the distance of the object.

8. The display apparatus of claim 5, wherein the user detecting part is configured to determine a distance of an object from the lens part, and

intensity of the image of the display panel is adjusted based on the distance.

9. The display apparatus of claim 5, wherein the object is a human face, and the user detecting part determines distances of portions of the human face from the lens part,

the lens part comprises a plurality of lens units, and

focal lengths of the lens units are adjusted based on the distances of the portions of the human face.

10. The display apparatus of claim 5, wherein the object is a human face, and the user detecting part is configured to determine a skin condition of the human face,

the lens part includes a plurality of lens units, and

the lens units of the lens part focus light having different wavelengths to different regions each corresponding to a position of different portions of the human face based on the skin condition of the human face.

11. The display apparatus of claim 1, wherein the lens part comprises a liquid crystal lens.

12. The display apparatus of claim 1, wherein the display panel and the lens part have curved shapes.

13. A display apparatus providing light therapy comprising a display panel, the display panel configured to display a first image based on input image data in a display mode, and

the display panel configured to display a second image having a therapy wavelength in a therapy mode.

14. The display apparatus of claim 13, wherein the therapy wavelength is one of about 415 nm representing blue, about 550 nm representing green and about 633 nm representing red.

15. The display apparatus of claim 13, further comprising a user detecting part determining a position of an object relative to the display panel.

16. The display apparatus of claim 15, wherein the user detecting part determines a distance of the object from the display panel, and

intensity of the second image is adjusted based on the distance.

17. The display apparatus of claim 16, further comprising a display panel driver driving the display panel,

wherein the display panel driver includes a therapy controlling part configured to manage the therapy wavelength, duration of therapy, and the intensity of the second image based on the distance.

18. The display apparatus of claim 17, wherein the object is a human face and the therapy controlling part configured to compare a skin condition of the human face before therapy and a skin condition of the human face after therapy using the user detecting part and to provide a comparison result to the display panel.
