Head mounted display device

1. A head mounted display device comprising:

a display unit divided into a first area having a high visibility to a user wearing the head mounted display device and a second area having a low visibility to the user wearing the head mounted display device; and

a memory which stores first compensation data corresponding to the first area of the display unit and second compensation data corresponding to the second area of the display unit,

wherein the first compensation data only requires larger storage than the second compensation data,

wherein each of the first compensation data corresponds to a unit of a first block and each of the second compensation data corresponds to a unit of a second block, and

wherein the number of pixels included in the second block is set different from that of pixels included in the first block.

2. The head mounted display of claim 1 , further comprising:

a lens unit which supplies an image displayed on the display unit to a user; and

a frame which fixes the display unit and the lens unit thereto.

3. The head mounted display of claim 1 , wherein the first area is set as a central area corresponding to each of left and right eyes of a user, and

wherein the second area is set as an area except for the first area.

4. The head mounted display of claim 1 , further comprising a position determiner which determines whether first data supplied from an outside belong to the first area or the second area.

5. The head mounted display of claim 4 , wherein the position determiner generates third data by adding position information corresponding to the first area or the second area to the first data.

6. The head mounted display of claim 5 , further comprising a timing controller for receiving the third data, and generating second data by changing bits of the third data using the first compensation data or the second compensation data.

7. The head mounted display of claim 5 , wherein the first area has a shape of a curve.

8. The head mounted display of claim 7 , wherein the first area has a shape of a circle.

9. The head mounted display of claim 8 , wherein, when following Inequality 1 is satisfied, the position determiner determines that the first data belong to the first area:

( x−x 0) 2 +( y−y 0) 2 <c,   Inequality 1

wherein, in Inequality 1, x0 and y0 denote a coordinate of a pixel located at a central portion of each of first panel and second panel, x and y denote a position coordinate of currently input first data, and c denotes a constant corresponding to a size of the first area.

10. The head mounted display of claim 7 , wherein the first area has a shape of an ellipse.

11. The head mounted display of claim 7 , wherein, when following Inequality 2 is satisfied, the position determiner determines that the first data belong to the first area:

( x−x 0) 2 +b ( y−y 0) 2 <c,   Inequality 2

wherein, in Inequality 2, x0 and y0 denote a coordinate of a pixel located at the central portion of each of first panel and second panel, x and y denote a position coordinate of currently input first data, c denotes a constant corresponding to a size of the first area, and b denotes a constant corresponding to the shape of the ellipse.

12. The head mounted display of claim 5 , wherein the first area has a shape of a polygon.

13. The head mounted display of claim 12 , wherein the first area has a shape of a quadrangle.

14. The head mounted display of claim 13 , wherein, when following Inequality 3 is satisfied, the position determiner determines that the first data belong to the first area:

( x 0′< x<x 1) and ( y 0′< y<y 1),  Inequality 3

wherein, in Inequality 3, x0′ denotes a coordinate of an X-axis start point of the first area, x1 denotes a coordinate of an X-axis end point of the first area, y0′ denotes a coordinate of a Y-axis start point of the first area, and y1 denotes a coordinate of a Y-axis end point of the first area.

15. The head mounted display of claim 1 , wherein each of the first compensation data is included in the first area, and corresponds to the unit of the first block including at least one pixel, and

wherein each of the second compensation data is included in the second area, and corresponds to the unit of the second block including at least two pixels.

16. The head mounted display of claim 15 , wherein the second block includes a larger number of pixels than the first block.

17. The head mounted display of claim 15 , wherein, when at least two pixels are included in the first block, the first compensation data is generated by a representative value of the at least two pixels of the first block.

18. The head mounted display of claim 17 , wherein the representative value is an average value of characteristics of the at least two pixels of the first block.

19. The head mounted display of claim 15 , wherein the second compensation data is generated by a representative value of the at least two pixels included in the second block.

20. The head mounted display of claim 19 , wherein the representative value is an average value of characteristics of the at least two pixels of the second block.
