Abstract

To provide a mobile phone which can be used without hampering convenience in a condition where functions of the mobile phone are switched and can improve operability. The mobile phone includes an optical sensor, a display element, a pixel circuit portion where a plurality of pixels having a plurality of transistors are arranged in matrix, an optical sensor control circuit which is connected to an optical sensor driver circuit for driving the optical sensor and reads a signal from the optical sensor, a display portion control circuit which is connected to a display element driver circuit for driving the display element and outputs an image signal for displaying an image on a display portion, a gradient detection portion for outputting a signal in accordance with a gradient of the mobile phone, and an arithmetic circuit for performing display in the pixel circuit portion by switching image signals output to the display portion control circuit with a signal from the gradient detection portion.

Claims

1. A mobile information-communication device comprising:

a housing having a long-side and a short-side;

a display portion;

a gradient detection portion;

an arithmetic circuit; and

a display potion control circuit,

wherein an output signal of the arithmetic circuit is configured to be switched by a signal for the display potion control circuit based on signals from the gradient detection portion,

wherein an image is configured to be displayed in the display portion based on the signal for the display potion control circuit, and

wherein the image is configured to be displayed in a first input key display region and a second input key display region with a character display region interposed therebetween so that a user operates the first input key display region with his/her left hand and the second input key display region with his/her right hand.

2. The mobile information-communication device according to claim 1, wherein the display portion includes one of a liquid crystal element, an EL element and an electrophoretic element.

3. The mobile information-communication device according to claim 1, wherein the mobile information-communication device is a mobile phone.

5. The mobile information-communication device according to claim 1, wherein the long-side of the housing is fixed when the short-side of the housing is inclined horizontally.

6. A mobile information-communication device comprising:

a housing having a long-side and a short-side;

a display portion;

a gradient detection portion;

an arithmetic circuit; and

a display potion control circuit,

wherein the display portion is configured to display a first input key display region on a left side of the display portion and a second input key display region on a right side of the display portion,

wherein the first input key display region is configured to be operated by a left hand of a user, and the second input key display region is configured to be operated by a right hand of the user,

wherein an output signal of the arithmetic circuit is configured to be switched by a signal in accordance with a degree of gradient of the housing when the short-side of the housing is inclined horizontally, and

wherein an image is configured to be displayed in the display portion using the output signal.

7. The mobile information-communication device according to claim 6, wherein the display portion includes one of a liquid crystal element, an EL element and an electrophoretic element.

8. The mobile information-communication device according to claim 6, wherein the mobile information-communication device is a mobile phone.

9. The mobile information-communication device according to claim 6, wherein the short-side of the housing is inclined horizontally by both hands of the user.
