Description

Display circuit device

This invention relates to a display circuit device, especially a display circuit device that does not require additional equipment. A display circuit card with a built-in bridge, especially one that can be used directly by using the switching function of the motherboard's hard disk bridge, so that the bandwidth can be directly upgraded without reducing the speed to achieve the required image transmission speed.

Peripheral Component Interconnect Express, PCIe) protocol is a type of computer bus protocol. It can be mainly used for interconnection within computers. It can also be used for interconnection with external chipset devices (such as display cards with display chips). It can also be used with computer peripherals. Input/output (I/O) devices are interconnected and can transmit data (such as multimedia data) to and from peripheral devices.

Taking a monitor as an example, a computer host may need to connect to multiple monitors due to actual needs. monitors, and each of these monitors has its own connection terminals, such as video graphic arrays (VGA) terminals, high definition multimedia interface (HDMI) terminals, serial digital interface (serial digital interface, SDI) terminal, and display port (display port, DP) terminal, etc. However, the I/O space is limited, and ordinary motherboards can only support up to three monitors to output images at the same time. This leads computer host suppliers to only configure three connection ports when designing the host casing.

For this reason, the traditional solution is to use a display that complies with the PCIe bus standard. card, which is mainly composed of several PCIe interfaces and a PCIe bridge. The golden finger of every PCIe interface The circuit is connected to the corresponding position of the PCIe bridge compatible with the PCIe interface on the display card, so that the display card can be plugged into a corresponding PCIe slot provided on a motherboard through the golden fingers. This allows monitors with specific connection terminals to be indirectly plugged into connection ports whose original shapes and specifications are incompatible with each other, and also enables the number of monitors plugged into a single host to exceed the number of connection ports on the chassis. However, in addition to being a cost, the use of a bridge will also occupy bandwidth, halving the network speed, weakening the signal, and easily generating noise.

In view of various problems in learning skills, in order to solve them simultaneously, a set of explicit techniques has been developed. The display card does not require a bridge and can be directly plugged into the motherboard for direct compatibility.
