Abstract
A computer keyboard with a monitor on the operating panel thereof. Data entered by users from the keyboard is synchronously displayed on the keyboard monitor, eliminating the need for a user to look back and forth at the positions of keys and the data displayed on the monitor during a data entry process. The keyboard can also be an independent input device used to enter data even when the keyboard is disconnected from the computer. Such a keyboard has a memory unit that can temporarily store the entered data while the keyboard is disconnected, and then load the data into the computer when the keyboard recovers its connection with the computer. Thus, the keyboard is capable of receiving and storing data when the keyboard is disconnected, and transmitted stored data upon reconnection with the computer.
Claims6
A computer keyboard for inputting data, capable of being disconnected from a computer system, comprising:
- a standard press key, having a plurality of keys for entering character data;
- a keyboard microcontroller (MCU) for generating a character code corresponding to the key;
- a monitor, disposed on the operating panel of the keyboard;
- a monitor microcontroller (MCU) for driving the monitor to display a bitmapped graphic pattern of the character entered from the standard press key;
- a memory unit for saving the character code;
- and
- a power supply unit for supplying the electric power required by the computer system,
- wherein, upon resuming a connection with the computer system, the keyboard microcontroller (MCU) sends the character code stored in the memory unit to the computer system, receives the bitmapped graphic pattern corresponding to the character code returned from the computer system, and then sends the bitmapped graphic pattern to the monitor microcontroller (MCU) for driving the monitor to display the bitmapped graphic pattern on the monitor.
