Abstract

A display apparatus and a graphic display method are provided. A display apparatus includes a graphic processing unit which converts data received from an external device into graphics, and a display unit which displays a graphics. Accordingly, the display apparatus can display a high quality 3-dimensional image.

Claims

1. A display apparatus comprising:

an interface unit which receives data used to generate graphics from an external device;

a graphic processing unit which generates the graphics using the received data; and

a display unit which displays the graphics generated by the graphic processing unit.

2. The display apparatus according to claim 1, wherein the interface unit receives the received data through a Peripheral Component Interconnect Express (PCIe) bus which is mounted in the external device.

3. The display apparatus according to claim 2, wherein the PCIe bus has an x1 lane.

4. The display apparatus according to claim 1, wherein the graphics are three-dimensional (3D) graphics, and includes objects which are disposed in a 3D graphic space.

5. The display apparatus according to claim 4, wherein the received data comprises at least one of a graphic command containing information regarding a graphical function to be called to generate the graphics, and graphics data, and

wherein the graphics data comprises at least one of coordinate information indicating coordinates of the objects, and rendering information indicating a graphical effect of the objects.

6. The display apparatus according to claim 5, wherein the rendering information comprises at least one of color information, gradation information, shadow information, and direction information.

7. The display apparatus according to claim 1, wherein the graphics are two-dimensional (2D) graphics, and the interface unit receives non-compressed data indicating the 2D graphics from the external device.

8. The display apparatus according to claim 1, wherein the received data received by the interface unit has a differential signal format including a differential signal, wherein the differential signal is one of Low-Voltage Differential Signaling (LVDS) and Transition Minimized Differential Signaling (TMDS).

9. The display apparatus according to claim 1, wherein if the interface unit is connected to the external device through a cable, the display unit operates as a dual display together with an external display unit mounted in the external device.

10. The display apparatus according to claim 1, wherein the graphic processing unit is one of a graphics processing unit (GPU) and a graphics card, the external device is one of a personal computer, a portable computer, a laptop computer, a netbook computer, and a portable game device, and the display apparatus is one of a monitor, a television, a portable multimedia player (PMP), and a table-top device.

11. A method of displaying graphics by a display having a display screen and a graphics processing unit, the method comprising:

receiving data used to generate graphics from an external device;

generating the graphics in the graphics processing unit by processing the received data; and

displaying the graphics on the display screen.

12. The display method according to claim 11, wherein the receiving of the received data, the received data are received through a Peripheral Component Interconnect Express (PCIe) bus which is mounted in the external device.

13. The display method according to claim 12, wherein the PCIe bus has an x1 lane.

14. The display method according to claim 11, wherein the graphics are 3-dimensional graphics, and includes objects which are disposed in a 3-dimensional graphic space.

15. The display method according to claim 14, wherein the received data comprises at least one of a graphic command containing information regarding a graphical function to be called to generate the graphics, and graphics data, and

wherein the graphics data comprises at least one of coordinate information indicating coordinates of the objects, and rendering information indicating a graphical effect of the objects.

16. The display method according to claim 15, wherein the rendering information comprises at least one of color information, gradation information, shadow information, and direction information.

17. The display method according to claim 11, wherein the graphics are 2-dimensional graphics, and in receiving the received data, non-compressed data indicating the 2-dimensional graphics are received from the external device.

18. The display method according to claim 11, wherein the received data received from the external device has a differential signal format including a differential signal, wherein the differential signal is one of Low-Voltage Differential Signaling (LVDS) and Transition Minimized Differential Signaling (TMDS).

19. The display method according to claim 11, wherein the external device is one of a personal computer, a portable computer, a laptop computer, a netbook computer, and a portable game device, and the display is mounted in one of a monitor, a television, a portable multimedia player (PMP), and a table-top device.
