Abstract

A display system and vehicle that have novel structures are provided. The display system includes a display panel, a correction circuit, and a memory circuit. The display panel is flexible. The display panel includes a display region and a non-display region. The memory circuit has a function of storing first data about the display region and second data about the non-display region. The non-display region has a region which overlaps with the display region when the display panel is bent. The correction circuit has a function of generating image data to be written to pixels in the display region on the basis of the first data and the second data.

First claim

What is claimed is:

1. A display system comprising:
a display panel comprising:
a display region; and
a non-display region; and

a control IC attached to the non-display region, the control IC comprising:
a memory circuit configured to store display region data;
a correction circuit configured to compress or enlarge first image data based on the display region data and convert into second image data for a size of the display region; and
a display driver IC configured to output the second image data to the display panel,

wherein the non-display region comprises a bending portion and is configured to be bent at the bending portion, and
wherein the control IC overlaps with the display region.

2. The display system according to claim 1 ,
wherein the correction circuit is configured to generate third image data to be applied to the non-display region, and
wherein the third image data is blank or black display.

3. The display system according to claim 1 ,
wherein the correction circuit is configured to compress or enlarge the first image data in accordance with the size of the display region.

4. The display system according to claim 1 ,
wherein the memory circuit comprises a memory cell,
wherein the memory cell comprises:
a first transistor whose semiconductor layer includes an oxide semiconductor; and
a capacitor, one electrode of the capacitor electrically connected to one of a source and a drain of the first transistor.

5. The display system according to claim 4 ,
wherein the memory cell further comprises a second transistor whose semiconductor layer includes silicon, and
wherein a gate of the second transistor is electrically connected to the one electrode of the capacitor and the one of the source and the drain of the first transistor.

6. The display system according to claim 1 , wherein the display region is positioned on a curved surface.

7. The display system according to claim 6 , wherein the second image data is configured to have less distortion in the display region on the curved surface.

8. A display system comprising:
a host controller;
a first display panel comprising:
a first display region; and
a first non-display region,

a first control IC comprising:
a first memory circuit configured to store first display region data;
a first correction circuit configured to receive first image data from the host controller and compress or enlarge the first image data based on the first display region data and convert into second image data for a size of the first display region; and
a first display driver IC configured to output the second image data to the first display panel,

a second display panel comprising:
a second display region; and
a second non-display region, and

a second control IC comprising:
a second memory circuit configured to store second display region data;
a second correction circuit configured to receive third image data from the host controller and process the third image data based on the second display region data to generate fourth image data to be written to the second display region; and
a second display driver IC configured to output the fourth image data to the second display panel,

wherein the first non-display region comprises a bending portion and is configured to be bent at the bending portion, and
wherein the first control IC overlaps with the first display region.

9. The display system according to claim 8 ,
wherein the first display region and the second display region are different in size, and
wherein the first display region data and the second display region data are different from each other.

10. The display system according to claim 8 ,
wherein the first correction circuit is configured to generate fifth image data to be applied to the first non-display region, and
wherein the fifth image data is blank or black display.

11. The display system according to claim 8 ,
wherein the first correction circuit is configured to compress or enlarge the first image data in accordance with the size of the first display region.

12. The display system according to claim 8 ,
wherein the first memory circuit comprises a memory cell,
wherein the memory cell comprises:
a first transistor whose semiconductor layer includes an oxide semiconductor; and
a capacitor, one electrode of the capacitor electrically connected to one of a source and a drain of the first transistor.

13. The display system according to claim 12 ,
wherein the memory cell further comprises a second transistor whose semiconductor layer includes silicon, and
wherein a gate of the second transistor is electrically connected to the one electrode of the capacitor and the one of the source and the drain of the first transistor.

14. The display system according to claim 8 , wherein the first display region is positioned on a curved surface.

15. The display system according to claim 14 , wherein the second image data is positioned on a curved surface.
