First Claim
1. A display apparatus adapted for a portable device, comprising:
- a storage unit configured for storing information;
a primary display capable of displaying a virtual keyboard in a power off state, wherein the virtual keyboard includes keys for editing information and keys for displaying information;
a secondary display;
a touch pad, positioned on the primary display covering an area of the keys for editing information and an area of the keys for displaying information, structured and arranged for generating an operational signal in response to a touch operation on the virtual keyboard; and
a processing unit, configured for recognizing the operational signal from the touch pad and performing a corresponding control on the primary display and the secondary display;
wherein, when the operational signal is generated in response to a touch operation on the touch pad corresponding to the keys for editing information of the virtual keyboard, the processing unit acts to display information corresponding to the operational signal on the secondary display;
when the operational signal is generated in response to a touch operation on the touch pad corresponding to the keys for displaying information of the virtual keyboard, the processing unit obtains the information stored in the storage unit and acts to display the information on the primary display;
when the processing unit has not received the operational signal for a predetermined time period from the touch pad corresponding to the keys for displaying information of the virtual keyboard, the processing unit acts to display the virtual keyboard on the primary display and acts to power off the primary display.
