Abstract

A portable electronic device comprises a double-sided display including a first display side and a second display side formed on a side opposite the first display side; a direct memory access (DMA) controller configured to read first image data from a memory; at least one sensor configured to detect at least one of a position change of the double-sided display and a movement of a user's pupil and to output a detection signal; a status signal generator configured to interpret the detection signal output and to output a status signal; a transmission order determiner configured to receive the first image data from the DMA controller, to determine a transmission order of the first image data based on the status signal, and to output second image data corresponding to the determined transmission order; and a display driver integrated circuit (IC) configured to transmit the second image data to the display.

First claim

What is claimed is:

1. A system, comprising:
a status signal generator configured to output a status signal to indicate one of a plurality of positions of at least one double-sided display; and
an image rotator coupled to the status signal, the image rotator configured to receive image data in a read order, and to output the image data in a transmission order, the transmission order being the same as the read order if the status signal indicates a first position of the at least one double-sided display, and the transmission order being a reverse of the read order if the status signal indicates a second position of the at least one double-sided display.

2. The system according to claim 1 , wherein the plurality of positions of the at least one double-sided display comprises an unfolded position and a folded position, and
wherein the first position comprises the unfolded position and the second position comprises the folded position.

3. The system according to claim 1 , wherein the at least one double-sided display comprises a double-sided display, a transparent double-sided display, a double-sided foldable display, a dual-sided foldable display, a double-sided foldable flexible display, or a dual-sided foldable flexible display.

4. The system according to claim 1 , wherein the at least one double-sided display comprises at least two double-sided displays.

5. The system according to claim 4 , wherein the status signal generator is further configured to output the status signal in response to at least one of an angle between the at least two double-sided displays, an orientation of one of the at least two double-sided displays, a rotation of one of the at least two double-sided displays or a rotation direction of one of the at least two double-sided displays.

6. The system according to claim 1 , further comprising:
a direct memory access (DMA) controller comprising an output coupled to the image rotator, the DMA controller being configured to output the image data to the image rotator; and
a display driver IC configured to receive the image data.

7. The system according to claim 1 , wherein the system comprises part of an electronic device comprising the at least one double-sided display.

8. A System on a Chip (SOC), comprising:
a direct memory access (DMA) controller configured to output image data in a read order;
a status signal generator configured to output a status signal to indicate one of a plurality of positions of at least one double-sided display, the plurality of positions comprising at least an unfolded position and a folded position, and a first position comprising the unfolded position and a second position comprising the folded position; and
an image rotator coupled to the status signal generator, the image rotator configured to receive the image data in the read order, and to output the image data in a transmission order, the transmission order being the same as the read order if the status signal indicates the first position of the at least one double-sided display, and the transmission order being a reverse of the read order if the status signal indicates the second position of the at least one double-sided display.

9. The SoC according to claim 8 , wherein the at least one double-sided display comprises a double-sided display, a transparent double-sided display, a double-sided foldable display, a dual-sided foldable display, a double-sided foldable flexible display, or a dual-sided foldable flexible display.

10. The SoC according to claim 8 , wherein the at least one double-sided display comprises at least two double-sided displays.

11. The SoC according to claim 10 , wherein the status signal generator is further configured to output the status signal in response to at least one of an angle between the at least two double-sided displays, an orientation of one of the at least two double-sided displays, a rotation of one of the at least two double-sided displays or a rotation direction of one of the at least two double-sided displays.

12. The SoC according to claim 8 , further comprising a display driver configured to receive the image data from the image rotator and to drive the at least one double-sided display with the image data received from the image rotator.

13. The SoC according to claim 8 , wherein the SoC comprises part of an electronic device comprising the at least one double-sided display.

14. The SoC according to claim 13 , wherein the electronic device comprises a computing device, a personal digital assistant (PDA), a laptop computer, a mobile computer, a web tablet, a wireless phone, a cell phone, a smart phone, a digital music player, or a wireline or wireless electronic device.

15. A system, comprising:
at least one double-sided display;
a status signal generator configured to output a first status signal to indicate an unfolded position of the at least one double-sided display and a second status signal to indicate a folded position of the at least one double-sided display; and
an image rotator coupled to the status signal generator, the image rotator configured to receive image data in a read order, and to output the image data in a transmission order, the transmission order being the same as the read order if the status signal generator outputs the first position signal, and the transmission order being a reverse of the read order if the status signal generator outputs the second position signal.

16. The system according to claim 15 , wherein the at least one double-sided display comprises a double-sided display, a transparent double-sided display, a double-sided foldable display, a dual-sided foldable display, a double-sided foldable flexible display, or a dual-sided foldable flexible display.

17. The system according to claim 15 , wherein the at least one double-sided display comprises at least two double-sided displays.

18. The system according to claim 17 , wherein the status signal generator is further configured to output the first status signal or the second status signal in response to at least one of an angle between the at least two double-sided displays, an orientation of one of the at least two double-sided displays, a rotation of one of the at least two double-sided displays or a rotation direction of one of the at least two double-sided displays.

19. The system according to claim 15 , wherein the system comprises part of an electronic device comprising the at least one double-sided display.

20. The system according to claim 19 , wherein the electronic device comprises a computing device, a personal digital assistant (PDA), a laptop computer, a mobile computer, a web tablet, a wireless phone, a cell phone, a smart phone, a digital music player, or a wireline or wireless electronic device.
