Abstract

Provided is a display device, which detects the proximity state of a display screen and an object on the display screen, based on capacitance detected by a capacitance detecting unit configured on the display screen, and corresponding to the proximity state, the display device determines one user interface to control out of a plurality of user interface screens that are displayed in layers on the display screen.

Claims

1. A display device comprising:

a proximity state detection unit that detects a proximity state between a display screen and an object on the display screen based on an electrostatic capacitance detected by an electrostatic capacitance detection unit configured on the display screen; and

a control user interface (UI) determination unit that determines which of a plurality of UI screens displayed in layers on the display screen is controlled in response to the proximity state.

2. The display device according to claim 1, wherein the proximity state detection unit detects one of a touch state, a proximity state, and a non-proximity state based on an amount of change in the electrostatic capacitance.

3. The display device according to claim 2, wherein the control UI determination unit determines that a UI screen in a lower layer of two UI screens displayed in layers is controlled when the proximity state is the touch state, and determines that a UI screen in an upper layer of the two UI screens is controlled when the proximity state is the proximity state.

4. The display device according to claim 1, further comprising:

an operation instruction reception unit that receives an operation instruction on the UI screen, and

an operation control unit that performs an operation control corresponding to the operation instruction received by the operation instruction reception unit for the UI screen determined to be controlled.

8. The display device according to claim 2, further comprising:

an operation instruction reception unit that receives an operation instruction on the UI screen, and

an operation control unit that performs an operation control corresponding to the operation instruction received by the operation instruction reception unit for the UI screen determined to be controlled.

9. The display device according to claim 3, further comprising:

an operation instruction reception unit that receives an operation instruction on the UI screen, and

an operation control unit that performs an operation control corresponding to the operation instruction received by the operation instruction reception unit for the UI screen determined to be controlled.

5. A display method of a display device comprising:

detecting a proximity state between a display screen and an object on the display screen based on an electrostatic capacitance detected by an electrostatic capacitance detection unit configured on the display screen; and

determining which of a plurality of UI screens displayed in layers on the display screen is controlled in response to the proximity state.

6. A program for causing a computer of a display device to function as:

a proximity state detection unit that detects a proximity state between a display screen and an object on the display screen based on an electrostatic capacitance detected by an electrostatic capacitance detection unit configured on the display screen; and

a control UI determination unit that determines which of a plurality of UI screens displayed in layers on the display screen is controlled in response to the proximity state.

7. A terminal device comprising:

a proximity state detection unit that detects a proximity state between a display screen and an object on the display screen based on an electrostatic capacitance detected by an electrostatic capacitance detection unit configured on the display screen; and

a control UI determination unit that determines which of a plurality of UI screens displayed in layers on the display screen is controlled in response to the proximity state.
