Abstract

An electronic apparatus includes first and second display devices having first and second display screens held in first and second housings, respectively. The second display screen is provided with a sensor which generates an output signal determining an input area in response to an external predetermined input to the second display screen. The first and second housings are connected together by a connecting mechanism so that an opening angle between the first and second housings can be adjusted. A first interface image is displayed on the second display screen. An instruction input to the interface image is determined on the basis of a sensor output signal. In response to the instruction input, a second display image is displayed in place of the first display image. In response to the instruction input, a second interface image is displayed in place of the first interface image.

Claims

1. An electronic apparatus comprising:

a first display device comprising a first housing and a first display screen which is held in the first housing;

a second display device comprising a second housing and a second display screen which is held in the second housing, the second display screen comprising a sensor which generates a sensor output signal depending on an input on the second display screen;

a connecting mechanism configured to connect the first and second housings together and be able to adjust an opening angle of the first housing and the second housing;

a display processing section configured to display a first display image on the first display screen and a first interface image on the second display screen;

a determining section configured to determine an instruction to the first interface image on the basis of the sensor output signal; and

a control section configured to control the display processing section in response to the instruction to display a second display image in place of the first display image on the first display screen and display a second interface image in place of the first interface image on the second display screen,

wherein the connecting mechanism sets the opening angle of the first housing and the second housing so that the first and second display screens can be viewed from one side of the electronic apparatus, and the second display screen is switched between display of the second interface image on the first interface image and non-display of the second interface image on the first interface image, the display of the second interface image on the first interface image being displayed on top of the first interface image as a translucent or opaque image.

2. The electronic apparatus according to claim 1, wherein the connecting mechanism sets the opening angle of the first housing and the second housing so that the first and second display screens can be viewed from opposite sides of the electronic apparatus, and the first and second display screens display the second display image and the second interface image corresponding to substantially the same image or the second display image and second interface image which are in a mirrored relationship.

3. The electronic apparatus according to claim 1, wherein the first display device further comprises a light source incorporated into the first housing to illuminate the first display screen, and the first housing comprises a structure configured to guide illumination light from the light source to the second display device as backlight illumination or a front-light illumination.

4. The electronic apparatus according to claim 1, wherein the first and second display screens forms one flexible and bendable display unit.

5. An electronic apparatus comprising:

a first display device comprising a first housing and a first display screen which is held in the first housing;

a second display device comprising a second housing and a second display screen which is held in the second housing, the second display screen comprising a sensor which generates a sensor output signal depending on an input on the second display screen;

a connecting mechanism configured to connect the first and second housings together and be able to adjust an opening angle of the first housing and the second housing;

a display processing section configured to display a first display image on the first display screen and a first interface image on the second display screen;

a determining section configured to determine an instruction to the first interface image on the basis of the sensor output signal; and

a control section configured to control the display processing section in response to the instruction to display a second display image in place of the first display image on the first display screen and display a second interface image in place of the first interface image on the second display screen,

wherein the first display device further comprises a light source incorporated into the first housing to illuminate the first display screen, and the first housing comprises a structure configured to guide illumination light from the light source to the second display device as backlight illumination or a front-light illumination.
