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.

5. 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. - View Dependent Claims (6, 7)
