Abstract

The present disclosure provides devices and techniques for correcting misalignment in a multi-display system by identifying a misalignment between a plurality of displays in the multi-display device and determining a line start position of at least one of the plurality of displays in response to identifying the misalignment. The techniques further include transmitting a first line start signal at the line start position of the at least one of the plurality of displays to correct the misalignment.

First claim

What is claimed is:

1. A method for correcting a mechanical misalignment in a multi-display system, comprising:
identifying a mechanical misalignment between a plurality of displays in the multi-display system;
determining a line start position of at least one of the plurality of displays in response to identifying the mechanical misalignment; and
transmitting a first line start signal to a gate line corresponding to the line start position of the at least one of the plurality of displays to correct the mechanical misalignment.

2. The method of claim 1 , wherein identifying the mechanical misalignment between the plurality of displays in the multi-display system comprises:
identifying a size of the mechanical misalignment for displayed information across a first display of the plurality of displays and a second display of the plurality of displays.

3. The method of claim 1 , wherein transmitting the first line start signal to the gate line corresponding to the line start position comprises:
selecting a start gate line from a plurality of gate lines of a first display based on the line start position; and
driving an image signal initiated through the selected start gate.

4. The method of claim 1 , wherein transmitting the first line start signal to the gate line corresponding to the line start position comprises:
inserting a dummy image signal through a first gate line of a plurality of gate lines of at least one display of the plurality of displays; and
driving an initial image signal through a second gate line of the plurality of gate lines of the at least one display of the plurality of displays.

5. The method of claim 1 , further comprising:
controlling, by a timing controller (TCON) integrated with the multi-display system, one or more of the identifying of the mechanical misalignment, the determining of the line start position, or the transmitting of the first line start signal.

6. The method of claim 1 , wherein the multi-display system in a first position is folded and in a second position is unfolded with the plurality of displays arranged such that a first display of the plurality of displays is positioned adjacent to a second display of the plurality of displays.

7. The method of claim 1 , wherein the mechanical misalignment is identified either manually by a user or automatically by a display manager.

8. A multi-display system for correcting a mechanical misalignment comprising:
a processor;
a memory coupled to the processor, wherein the memory includes instructions executable by the processor to:
identify a mechanical misalignment between a plurality of displays in the multi-display system;
determine a line start position of at least one of the plurality of displays in response to identifying the mechanical misalignment; and
transmit a first line start signal to a gate line corresponding to the line start position of the at least one of the plurality of displays to correct the mechanical misalignment.

9. The multi-display system of claim 8 , wherein the instructions to identify the mechanical misalignment between the plurality of displays in the multi-display system are further executable by the processor to:
identify a size of the mechanical misalignment for displayed information across a first display of the plurality of displays and a second display of the plurality of displays.

10. The multi-display system of claim 8 , wherein the instructions to transmit the first line start signal to the gate line corresponding to the line start position are further executable by the processor to:
select a start gate line from a plurality of gate lines of a first display based on the line start position; and
drive an image signal initiated through the selected start gate.

11. The multi-display system of claim 8 , wherein the instructions to transmit the first line start signal to the gate line corresponding to the line start position are further executable by the processor to:
insert a dummy image signal through a first gate line of a plurality of gate lines of at least one display of the plurality of displays; and
drive an initial image signal through a second gate line of the plurality of gate lines of the at least one display of the plurality of displays.

12. The multi-display system of claim 8 , wherein the multi-display system in a first position is folded and in a second position is unfolded with the plurality of displays arranged such that a first display of the plurality of displays is positioned adjacent to a second display of the plurality of displays.

13. The multi-display system of claim 1 , wherein the mechanical misalignment is identified either manually by a user or automatically by a display manager associated with the processor.

14. A non-transitory computer-readable medium for correcting a mechanical misalignment in a multi-display system comprising instructions for:
identifying a mechanical misalignment between a plurality of displays in the multi-display system;
determining a line start position of at least one of the plurality of displays in response to identifying the mechanical misalignment; and
transmitting a first line start signal to a gate line corresponding to the line start position of the at least one of the plurality of displays to correct the mechanical misalignment.

15. The non-transitory computer-readable medium of claim 14 , wherein the instructions for identifying the mechanical misalignment between the plurality of displays in the multi-display system further include instructions for:
identifying a size of the mechanical misalignment for displayed information across a first display of the plurality of displays and a second display of the plurality of displays.

16. The non-transitory computer-readable medium of claim 14 , wherein the instructions for transmitting the first line start signal to the gate line corresponding to the line start position further include instructions for:
selecting a start gate line from a plurality of gate lines of a first display based on the line start position; and
driving an image signal initiated through the selected start gate.

17. The non-transitory computer-readable medium of claim 14 , wherein the instructions for transmitting the first line start signal to the gate line corresponding to the line start position further include instructions for:
inserting a dummy image signal through a first gate line of a plurality of gate lines of at least one display of the plurality of displays; and
driving an initial image signal through a second gate line of the plurality of gate lines of the at least one display of the plurality of displays.

18. The non-transitory computer-readable medium of claim 14 , further comprising instructions for:
controlling, by a timing controller (TCON) integrated with the multi-display system, one or more of the identifying of the mechanical misalignment, the determining of the line start position, or the transmitting of the first line start signal.

19. The non-transitory computer-readable medium of claim 14 , wherein the multi-display system in a first position is folded and in a second position is unfolded with the plurality of displays arranged such that a first display of the plurality of displays is positioned adjacent to a second display of the plurality of displays.

20. The computer-readable medium of claim 14 , wherein the mechanical misalignment is identified either manually by a user or automatically by a display manager.
