Abstract

A computer, a graphic card, a display apparatus and a method of updating information is described, wherein, the computer has a first status and a second status, and the system power consumption of computer in the first status is larger than the system power consumption of computer in the second status. The computer includes a graphic card having display memory and a display apparatus connected to the graphic card, and further includes an input processing module for acquiring input information when the computer is in the second status, and updating first display information stored in the display memory outputted to the display apparatus according to the input information to obtain second display information. The graphic card outputs the second display information to the display apparatus when the computer is in the second status.

First claim

What is claimed is:

1. A computer having a first status and a second status, wherein, a system power consumption of the computer in the first status is larger than a system power consumption of the computer in the second status, and the computer comprises a graphic card having a display memory and a display apparatus connected to the graphic card, the computer further comprising:
an input processing module for acquiring input information when the computer is in the second status, and updating first display information stored in the display memory outputted to the display apparatus according to the input information to obtain second display information;
the graphic card outputting the second display information to the display apparatus when the computer is in the second status;
wherein the graphic card comprises
a conversion module for converting the second display information in the display memory into an image signal, and outputting it to the display apparatus;
a graphic card power supply management module and a graphic processing unit; and,
wherein the graphic card power supply management module controls the graphic processing unit to be in a non-powered status, and controls the display memory, the conversion module, and the input processing module to be in a powered status when the computer is in the second status according to a control instruction issued by a computer processing unit when the computer is in the first state.

2. The computer according to claim 1 , wherein, the display apparatus has a touch screen, and the input processing module comprises:
an acquiring module for acquiring the input information inputted through the touch screen;
an updating module for storing the input information at a location stored in the display memory corresponding to the location of the input information on touch screen according to the definition of the display apparatus, and superimposing the input information and the original first display information in the display memory to obtain the second display information.

3. A graphic card applied to a computer having a first status and a second status, wherein, a system power consumption when the computer is in the first status is larger than a system power consumption when the computer is in the second status, and the graphic card comprises a graphic processing unit and a display memory storing display information, the graphic card further comprising:
an input processing module for acquiring input information when the graphic processing unit is in a status corresponding to the second status of the computer, and updating the first display information stored in the display memory according to the input information to obtain the second display information;
a conversion module for converting the second display information into an image signal when the graphic processing unit is in a status corresponding to the second status of the computer, and outputting to a display on the display apparatus of the computer;
a graphic card power supply management module and a graphic processing unit; and,
the graphic card power supply management module is for controlling the graphic processing unit to be in a non-powered status, and controlling the display memory, the conversion module, and the input processing module to be in a powered status when the computer is in the second status according to a control instruction issued by a computer processing unit when the computer is in the first state.

4. A display apparatus applied to the computer including a graphic card, the computer having a first status and a second status, wherein, a system power consumption when the computer is in the first status is larger than a system power consumption when the computer is in the second status, and the display apparatus comprises a display screen, the display apparatus further comprising:
an input processing module for acquiring input information when the computer is in the second status, and updating the first display information stored in the display memory of the graphic card outputted to the display screen according to the input information to obtain the second display information;
the graphic card comprises:
a conversion module to convert the second display information into an image signal when the computer is in the second status, and outputting it to the display screen;
a graphic card power supply management module and a graphic processing unit; and,
the graphic card power supply management module is for controlling the graphic processing unit to be in a non-powered status, and controlling the display memory, the conversion module, and the input processing module to be in a powered status when the computer is in the second status according to a control instruction issued by a computer processing unit when the computer is in the first state.

5. The display apparatus according to claim 4 , wherein the display screen is a touch screen, and the input processing module comprises:
an acquiring module for acquiring the input information inputted through the touch screen;
an updating module for storing the input information at a location in the display memory corresponding to the location of the input information on the touch screen according to the definition of the display apparatus, and superimposing the input information and the original first display information in the display memory to obtain the second display information.

6. The display apparatus according to claim 5 , wherein, the input processing module is powered by a power supply of the display apparatus through the power supply management module of the display apparatus.

7. A method for updating the display information applied to a computing apparatus, the computing apparatus having a first status and a second status, wherein, a system power consumption when the computing apparatus is in the first status is larger than a system power consumption when the computing apparatus is in the second status, the computing apparatus comprises a graphic card including a display memory, and the display memory stores the first display information outputted to the display apparatus when the computing apparatus is in the second status, the method comprising:
acquiring the input information;
updating the first display information in the display memory according to the input information to obtain the second display information;
outputting the second display information to the display apparatus;
wherein the graphic card comprises:
a conversion module for converting the second display information in the display memory into an image signal and outputting it to the display apparatus;
the method further comprising controlling by the controlling, by the graphic power supply management module, the graphic processing unit to be in a non-powered status, and the display memory, the conversion module, and the input processing module to be in a powered status when the computer is in the second status according to a control instruction issued by a central processing unit when the computer is in the first status.

8. The method according to claim 7 , wherein, the step of obtaining the input information comprises obtaining the input information inputted through the touch screen of the display apparatus of the computing apparatus.

9. The method according to claim 8 , wherein, the step of updating the first display information in the display memory according to the input information comprises storing the input information at a location in the display memory corresponding to the location of the input information on the touch screen according to the definition of the display apparatus, and superimposing the input information and the original first display information in the display memory
