Apparatus for controlling a pixel arrangement in a display unit
View Patent ↗A display unit may include a display screen device to display contents formed by pixels based on image data, a parallax barrier including pixels forming slit parts and mask parts and arranged to display an autostereoscopic presentation in combination with the display screen device, and a sensor to sense a rotation of the display unit about an axis perpendicular to a surface of the display screen device from a reference rotational position. A pixel arrangement of the display screen device and a pixel arrangement of the parallax barrier may be rotated depending on the rotation of the display unit from the reference rotational position.
1. A display unit comprising:
a display screen device configured to display contents formed by a plurality of pixels based on image data;
a parallax barrier including a plurality of pixels in a pixel arrangement forming slit parts and mask parts and configured to display an autostereoscopic presentation in combination with the display screen device;
a sensor configured to detect a rotation of the display unit about an axis perpendicular to a surface of the display screen device from a reference rotational position; and
a processor, wherein an arrangement of the plurality of pixels of the display screen device and the pixel arrangement of the parallax barrier are configured to rotate in a first direction in response to detection of the rotation of the display unit in a second direction opposite to the first direction from the reference rotational position by the sensor, the rotation of the pixel arrangement of the display screen device and parallax barrier is equal in magnitude and opposite in direction to the rotation of the display unit, so that the contents formed by the pixels of the display screen device and the slit parts and mask parts formed by the pixels of the parallax barrier are remapped to compensate for the rotation of the display unit, wherein the pixels of the mask parts of the parallax barrier are at least partially opaque in a first mode and transparent in a second mode,
wherein a resolution of the pixel arrangement of the parallax barrier is higher than a resolution of the pixel arrangement of the display screen device.
2. The display unit as claimed in claim 1 , wherein the processor variably adjusts a size of the contents to be displayed to fit within a display area of the display screen device of the rotated display unit.
3. The display unit as claimed in claim 1 , wherein the processor controls the pixel arrangement of the display screen device and the pixel arrangement of the parallax barrier based on the rotation of the display unit from the reference rotational position detected by the sensor.
4. An electronic apparatus comprising:
a display unit including a display screen device configured to display contents formed by a plurality of pixels based on image data, and a parallax barrier including a plurality of pixels in a pixel arrangement forming slit parts and mask parts and configured to display an autostereoscopic presentation in combination with the display screen device;
a sensor configured to the display unit to detect a rotation of the display unit about an axis perpendicular to a surface of the display screen device from a reference rotational position; and
a processing unit, wherein an arrangement of the plurality of pixels of the display screen device and the pixel arrangement of the parallax barrier are configured to rotate in a first direction in response to detection of the rotation of the display unit in a second direction opposite to the first direction from the reference rotational position by the sensor, the rotation of the pixel arrangement of the display screen device and parallax barrier is equal in magnitude and opposite in direction to the rotation of the display unit, so that the contents formed by the pixels of the display screen device and the slit parts and mask parts formed by the pixels of the parallax barrier are remapped to compensate for the rotation of the display unit, wherein the pixels of the mask parts of the parallax barrier are at least partially opaque in a first mode and transparentin a second mode,
wherein a resolution of the pixel arrangement of the parallax barrier is higher than a resolution of the pixel arrangement of the display screen device.
5. The electronic apparatus as claimed in claim 4 , wherein the processing unit variably adjusts a size of the contents to be displayed to fit within a display area of the display screen device of the rotated display unit.
