Abstract
A control unit activates a touch sensor according to a predetermined state, for example, an open or closed state of a casing or a side key depressed state and changes, after the elapse of time for performing calibration (about 500 ms), the touch sensor to a state in which contact operation by the touch sensor can be performed. On the other hand, the control unit causes a sub-display unit to display a predetermined rendered image, for example, a character string “touch sensor is operable.” after the elapse of the time for performing calibration.
Claims8
A display apparatus comprising:
- a display;
- a touch sensor that detects touch operation;
- and
- a control unit that performs control of the display and the touch sensor, characterized in that
- the control unit controls the display to display a predetermined rendered image after the touch sensor changes to a usable state.
A display apparatus comprising:
- a touch sensor that detects touch operation and requires first predetermined time from start of activation until the touch sensor changes to a usable state;
- a display that requires second predetermined time shorter than the first predetermined time from the start of activation until the display changes to a displayable state;
- and
- a control unit that controls an operation of the touch sensor and an operation of the display, characterized in that
- the control unit performs control for starting, after starting the activation of the touch sensor, the activation of the display and causing the display to display a predetermined rendered image before elapse of the first predetermined time.
A display apparatus comprising:
- a touch sensor that detects touch operation;
- a display unit that performs display related to content of operation by the touch sensor;
- and
- a control unit that performs control of the display unit and the touch sensor, characterized in that
- the control unit controls the display unit to perform display after the touch sensor changes to a usable state.
