Abstract

An external display system for displaying data of an input operating interface comprises: a computer module comprising a host, a display and a keyboard; a mouse module comprising a sensor unit, a first USB transmission interface unit, a control unit and a switch unit; an external display module comprising a second USB transmission interface unit, a microprocessor, a storage unit and a display unit. Upon receiving the triggering signal, the mouse module sends a signal to the microprocessor via the host. The microprocessor retrieves the status non-video data or the setting non-video data, generates and displays a status video data and/or a setting video data on the display unit. Or the microprocessor retrieves and transfers the setting non-video data to the host, and the host generates and transfers the setting video data to the display.

Claims

1. An external display system for displaying data of an input operating interface, comprising:

a computer module (1) comprising;

a host (11) having a first USB connection port (111) and a second USB connection port (112);

a display (13) electrically coupled to the host (11); and

a keyboard (12) electrically coupled to the host (11);

a mouse module (2) comprising;

a sensor unit (25) configured to retrieve a status non-video data corresponding to current usage status of a mouse for controlling icon movement in the pictures displayed on the displayer (13);

a first USB transmission interface unit (22) electrically coupled to the first USB connection port (111);

a control unit (21) electrically coupled with the first USB transmission interface unit (22) and the sensor unit (25), and processing the first non-video data, wherein the control unit (21) further comprises a memory or an internal buffer for storing the status non-video data; and

a switch unit (23) electrically coupled to the control unit (21) for sending a triggering signal to the control unit (21); and

an external display module (3) electrically coupled with the host (11) of the computer module (1), comprising;

a second USB transmission interface unit (36) electrically coupled with the host (11);

a microprocessor (32) electrically coupled with the second USB transmission interface unit (36);

a storage unit (33) electrically coupled with the microprocessor (32), the storage unit (33) being preloaded or present with a setting non-video data corresponded to the parameters of the computer module (1) or the mouse module(2);

a display unit (34) electrically coupled with the microprocessor (32);

wherein upon receiving the triggering signal, the control unit (21) triggers the first USB transmission interface unit (22) to send a first signal to the host (11) via the first USB connection port (111);

in response to the first signal, the host (11) sends a second signal to the microprocessor (32) of the external display module (3) for processing via the second USB connection port (112); and

in response to the second signal, the microprocessor (32) retrieves the status non-video data from the control unit (21) or the setting non-video data from the storage unit (33), and generates a status video data and/or a setting video data according to the status non-video data and/or the setting non-video data, and display the status video data or the setting video data on the display unit (34) of the external display module (3);

or

the microprocessor (32) retrieves the setting non-video data from the storage unit (33) and transfers the setting non-video data to the host (11) via the mouse module (2), and then the host (11) of the computer module (1) generates the setting video data according to the setting non-video data, and transfers the setting video data to the display (13) for displaying.

2. The external display system of claim 1, wherein computer module (1) is a desktop computer or a notebook computer.

3. The external display system of claim 1, wherein the second USB connection port (112) is electrically coupled with the second USB transmission interface unit (36).

4. The external display system of claim 1, wherein the switch unit (23) at least comprises a left button, a right button and a wheel.

5. The external display system of claim 1, wherein the storage unit (33) is an Electrically-Erasable Programmable Read-Only Memory (EEPROM) or a Flash Memory.

6. The external display system of claim 1, wherein the display unit (34) is a LCD.

7. The external display system of claim 1, wherein the external display module (3) further comprises a scaler electrically coupled the microprocessor (32) and the display unit (34), the scaler transforms the first video data to a display format data corresponded to a display format of the display unit (34) and transfers the display format data to the display unit (34) for displaying.

8. The external display system of claim 7, wherein the display format data conforms to the standard of LVDS (Low-Voltage Differential Signaling).

9. The external display system of claim 1, wherein the status non-video data comprises a data of a key press count, a wheel roll count, an usage time length of the mouse module (2).

10. The external display system of claim 1, wherein the setting non-video data comprises the operation key settings of a computer games or a software, the default parameters of the mouse module (2) or the keyboard (12), or the parameter setting values of the sensors.
