Description

Technical Field

[0001] This utility model relates to an electronic device with an independent graphics card. Background Technology

[0002] In recent years, the number of display interfaces on personal computers that have both integrated graphics and onboard discrete graphics has been decreasing, and there is usually no dedicated display interface for the discrete graphics card. Therefore, when calculating image information to display the screen, only the discrete graphics card is used for processing, but the integrated graphics still needs to output display signals to the display interface, which prevents the discrete graphics card from fully utilizing its performance. Utility Model Content

[0003] This invention provides an electronic device comprising a processor, a discrete graphics card, a first display interface, and a connector. The discrete graphics card is coupled to the processor and is used to output a first display signal. The connector is coupled to the discrete graphics card and is used to receive the first display signal. The connector is connected to the first display interface via a cable to transmit the first display signal to the first display interface.

[0004] In an embodiment of this utility model, it further includes: a core graphics card, configured inside the processor, for outputting a second display signal; and a second display interface, coupled to the processor, for receiving the second display signal.

[0005] In an embodiment of this utility model, the processor, the discrete graphics card, and the connector are integrated on the motherboard.

[0006] In an embodiment of this utility model, the connector is integrated on the motherboard near the discrete graphics card.

[0007] In an embodiment of this utility model, the first display interface is disposed on the bracket.

[0008] In an embodiment of this utility model, the bracket is installed in a slot provided on the outer casing of the electronic device.

[0009] In an embodiment of this utility model, the discrete graphics card and the processor are interconnected via a bus.

[0010] In an embodiment of this utility model, the discrete graphics card is an onboard discrete graphics card.

[0011] In embodiments of this utility model, the first display interface and the second display interface include at least one of a high-definition multimedia interface, a DisplayPort, a digital visual interface, and a video graphics array.

[0012] In an embodiment of this utility model, the discrete graphics card detects whether the first display interface is connected to the monitor. When the discrete graphics card detects that the first display interface is connected to the monitor, it outputs the first display signal.

[0013] Based on the above, the electronic device of this invention can, with the assistance of a connector, directly output display signals from a dedicated graphics card to the display interface. In this way, the performance of the dedicated graphics card can be fully utilized, improving image quality.

[0014] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below, and detailed descriptions are provided in conjunction with the accompanying drawings. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of an electronic device according to an embodiment of the present invention. Detailed Implementation

[0016] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element reference numerals are used in the drawings and description to denote the same or similar parts.

[0017] Please refer to Figure 1 The electronic device 100 of this utility model is, for example, a personal computer such as a desktop computer or a laptop computer. The electronic device 100 includes a processor 110, a dedicated graphics card 120, a first display interface 130, a connector 140, an integrated graphics card 150, and a second display interface 160.

[0018] Processor 110 is, for example, a Central Processing Unit (CPU), or other programmable general-purpose or special-purpose microprocessor, digital signal processor (DSP), programmable controller, application-specific integrated circuit (ASIC), or other similar components or combinations thereof. Processor 110 is integrated on a motherboard MB within electronic device 100. The motherboard MB is implemented, for example, by a printed circuit board (PCB) or a printed circuit board assembly (PCBA).

[0019] A discrete graphics card 120 is coupled to a processor 110. In this embodiment, the discrete graphics card 120 is an onboard discrete graphics card, integrated onto the motherboard MB within the electronic device 100, just like the processor 110. The discrete graphics card 120 and the processor 110 are interconnected via, for example, a PCIe bus BS. The discrete graphics card 120 can be used to output a first display signal Sd1.

[0020] The first display interface 130 and the second display interface 160 include, for example, at least one of High Definition Multimedia Interface (HDMI), DisplayPort, Digital Visual Interface (DVI), and Video Graphics Array (VGA), and can be connected to a corresponding display (e.g., a Liquid Crystal Display (LCD), a Light-Emitting Diode (LED), a Field Emission Display (FED), or other types of panels). In this embodiment, as... Figure 1 As shown, the first display interface 130 is mounted on a bracket BT. The bracket BT, for example, conforms to a general PCIe specification and can be installed in a slot provided on the housing of the electronic device 100.

[0021] Connector 140 couples to discrete graphics card 120. Connector 140, for example, can accommodate high-speed signal transmission, with shorter pin lengths. Figure 1 In the middle, connector 140 is integrated on the motherboard MB, near the discrete graphics card 120, to facilitate receiving the first display signal Sd1 from the discrete graphics card 120.

[0022] Furthermore, connector 140 is connected to the first display interface 130 via cable CB to transmit the first display signal Sd1 to the first display interface 130 via cable CB. Thus, the corresponding image can be displayed on the monitor connected to the first display interface 130.

[0023] The integrated graphics 150 is located inside the processor 110. The integrated graphics 150 can be used to output a second display signal Sd2.

[0024] The second display interface 160 is coupled to the processor 110. The second display interface 160 is used to receive a second display signal Sd2 from the integrated graphics 150. Thus, the corresponding image can be displayed on the monitor connected to the second display interface 160.

[0025] With the above structure, when calculating image information using the discrete graphics card 120, the discrete graphics card 120 can directly output the first display signal Sd1 to the first display interface 130 with the assistance of the connector 140, so as to display the corresponding image on the monitor connected to the first display interface 130. In this way, the performance of the discrete graphics card 120 can be fully utilized and the image quality can be improved.

[0026] When the discrete graphics card 120 outputs the first display signal Sd1, the core graphics card 150 will stop outputting the second display signal Sd2, but this invention is not limited thereto. In other embodiments, the discrete graphics card 120 and the core graphics card 150 may also output display signals simultaneously to display images on different monitors at the same time.

[0027] In one embodiment, the discrete graphics card 120 can detect whether the first display interface 130 is connected to the corresponding monitor. When the discrete graphics card 120 detects that the first display interface 130 is connected to the corresponding monitor, it outputs a first display signal Sd1 to the connector 140 to transmit the first display signal Sd1 to the first display interface 130 via the cable CB, and displays the corresponding image on the monitor connected to the first display interface 130.

[0028] In summary, the electronic device of this invention, with the assistance of a connector, allows the discrete graphics card to directly output display signals to the display interface. This not only expands the number of display interfaces while maintaining compatibility with typical onboard discrete graphics card solutions, but also fully utilizes the performance of the discrete graphics card, improving image quality.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
