Abstract

An electronic device includes a flexible display substrate including a transmission-type display region and a non-transmission-type display region, and the flexible display substrate is fixed on one or more of housings. Portion of the housing is transparent, and the transmission-type display region overlaps with this transparent portion. In addition, the non-transmission-type display region overlaps with opaque components such as an arithmetic processing unit, a battery, or the like stored in the housing. Display contents and display modes are used properly for the transmission-type display region and the non-transmission-type display region, thereby making it possible to display various images. Other embodiments are also claimed.

Claims

1. An electronic device comprising:

a flexible display substrate comprising a first display region and a second display region;

an arithmetic processing unit; and

a housing,

wherein the first display region comprises a first region which is transmission type,

wherein the second display region is a non-transmission-type display region,

wherein the arithmetic processing unit is configured to supply an image signal to the flexible display substrate, and

wherein the arithmetic processing unit is stored in the housing.

2. The electronic device according to claim 1,

wherein the arithmetic processing unit and the first display region do not overlap with each other and a background behind the first display region is visible when display is performed in the flexible display substrate.

3. The electronic device according to claim 1,

wherein the second display region is fixed to the housing.

4. The electronic device according to claim 1,

wherein the second display region and the arithmetic processing unit are fixed to overlap.

5. The electronic device according to claim 1,

wherein part of the housing is transparent.

6. The electronic device according to claim 1,

wherein the first display region and the second display region are coextensive with each other when the flexible display substrate is bent.

7. An electronic device comprising:

a flexible display substrate comprising a first display region, a second display region and a third display region;

an arithmetic processing unit fixed to the flexible display substrate; and

a housing,

wherein the second display region is provided between the first display region and the third display region,

wherein the third display region is provided between the second display region and the arithmetic processing unit,

wherein a part of the flexible display substrate is fixed to the housing,

wherein the second display region comprises a first region which is transmission-type,

wherein the first display region is a non-transmission-type display region,

wherein the third display region is a non-transmission-type display region, and

wherein the arithmetic processing unit is configured to supply an image signal to the flexible display substrate.

8. The electronic device according to claim 7,

wherein the arithmetic processing unit and the second display region do not overlap with each other and a background behind the second display region is visible when display is performed in the flexible display substrate when the third display region is not bent, and

wherein the arithmetic processing unit and the second display region do not overlap with each other and the background behind the second display region is visible when display is performed in the flexible display substrate when the third display region is bent.

9. The electronic device according to claim 7,

wherein the second display region is fixed to the housing.
