Abstract

The disclosed display device may include a display screen having (1) a front surface and (2) at least one display region that emits image light from the front surface, the at least one display region including a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixel columns, the plurality of pixel rows and the plurality of pixel columns each extending obliquely relative to a peripheral edge of the front surface. The display device may also include a display driver circuit for driving the plurality of pixels of the at least one display region. The display driver circuit may be disposed adjacent to the peripheral edge of the front surface. Various other methods, systems, and devices are also disclosed.

First claim

What is claimed is:

1. A display device comprising:
a display screen that comprises:
a front surface; and
a pair of display regions that emit image light from the front surface, the pair of display regions being disposed apart from each other in a longitudinal direction of the display screen, each of the pair of display regions comprising a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixel columns, the plurality of pixel rows and the plurality of pixel columns each extending obliquely relative to a peripheral edge of the front surface; and

a display driver circuit for driving the plurality of pixels of each of the pair of display regions, wherein the display driver circuit is disposed adjacent to the peripheral edge of the front surface,
wherein:
a first display region of the pair of display regions comprises a first set of scanning lines;
a second display region of the pair of display regions comprises a second set of scanning lines; and
each of the first set of scanning lines extends in a first scanning line direction and each of the second set of scanning lines extends in a second scanning line direction that is different than the first scanning line direction.

2. The display device of claim 1 , wherein:
each of the plurality of pixel rows of the first display region extends in the first scanning line direction and each of the plurality of pixel rows of the second display region extends in the second scanning line direction; and
the pair of display regions each further comprise a plurality of data lines extending parallel to the plurality of pixel columns.

3. The display device of claim 2 , wherein the display driver circuit is electrically coupled to the first set of scanning lines, the second set of scanning lines, and the plurality of data lines of each of the pair of display regions.

4. The display device of claim 1 , wherein:
the plurality of pixel rows of each of the pair of display regions each extend in a row direction having an angle of approximately 45° with respect to the peripheral edge of the front surface; and
the plurality of pixel columns of each of the pair of display regions each extend in a column direction having an angle of approximately 45° with respect to the peripheral edge of the front surface.

5. The display device of claim 1 , wherein a perimeter of the plurality of pixels in each of the pair of display regions comprises a nonrectangular shape.

6. The display device of claim 5 , wherein the perimeter of the plurality of pixels in each of the pair of display regions comprises an octagonal shape.

7. The display device of claim 5 , wherein at least one side of the perimeter of the plurality of pixels in each of the pair of display regions intersects multiple scanning lines and multiple data lines.

8. The display device of claim 1 , wherein:
the display driver circuit is disposed apart from each display region of the pair of display regions in a lateral direction of the display screen.

9. The display device of claim 1 , wherein the display screen comprises a nonrectangular periphery surrounding the front surface.

10. The display device of claim 1 , wherein the display screen further comprises a backlight unit comprising:
a light source; and
light guide plate comprising a pattern of microstructures for diffusing light from the light source, wherein a density of the microstructures is lower in a non-display region of the display screen.

11. The display device of claim 10 , wherein the microstructures of the pattern of microstructures are not formed in the non-display region of the display screen.

12. The display device of claim 10 , wherein the pattern of microstructures comprises a plurality of diffuser dots.

13. The display device of claim 10 , wherein the non-display region of the display screen is located between the pair of display regions.

14. The display device of claim 10 , wherein the light source is disposed adjacent to a peripheral side of the display screen adjoining the peripheral edge of the front surface.

15. A head-mounted-display device comprising:
the display device of claim 1 ; and
a display housing surrounding the display device.

16. A display device comprising:
a display screen that comprises:
a front surface;
a pair of display regions that emit image light from the front surface; and
a backlight unit comprising:
a light source; and
a light guide plate comprising a pattern of microstructures for diffusing light from the light source, wherein a density of the microstructures is lower in a non-display region of the display screen located between the pair of display regions.

17. The display device of claim 16 , wherein the pattern of microstructures comprises a plurality of diffuser dots.

18. A method comprising:
receiving initial image data for displaying an image on a display device in an initial orientation;
modifying the initial image data to generate modified image data for displaying the image on the display device in a rotated orientation that is rotated by a selected angle of rotation relative to the initial orientation; and
driving the display device based on the modified image data, the display device comprising:
a front surface; and
at least one display region that emits, from the front surface, image light forming the image, the at least one display region comprising a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixel columns, at least one of the plurality of pixel rows or the plurality of pixel columns extending at an extension angle relative to a peripheral edge of the front surface, wherein the extension angle is equivalent to the selected angle of rotation.

19. The method of claim 18 , wherein:
the at least one display region comprises a first display region and a second display region;
receiving the initial image data further comprises:
receiving a first set of initial image data for displaying a first image in the first display region in a first initial orientation; and
receiving a second set of initial image data for displaying a second image in the second display region in a second initial orientation; and

modifying the initial image data further comprises:
modifying the first set of initial image data to generate a first set of modified image data for displaying the first image in the first display region in a first rotated orientation that is rotated by a first selected angle of rotation relative to the first initial orientation; and
modifying the second set of initial image data to generate a second set of modified image data for displaying the second image in the second display region in a second rotated orientation that is rotated by a second selected angle of rotation relative to the second initial orientation, wherein the second selected angle of rotation is different than the first selected angle of rotation.
