Multi-signal source HDMI (High Definition Multimedia Interface) display switching device

Abstract

The invention discloses a multi-signal source HDMI (High Definition Multimedia Interface) display switching device and relates to the field of a display device. The multi-signal source HDMI display switching device comprises an HDMI display, at least one signal input source and a channel control device. The channel control device comprises a switching turntable, and a switching button, a separablecontact head which are set at one side of the switching turntable. The channel control device also comprises an input port, a converter, an output channel and an output port. Through adoption of an electromechanical combination thought, signals are freely switched by carrying out pressing and rotating operations on the switching button; the multi-signal source HDMI display switching device is characterized by high compatibility and is friendly to different interfaces of new and old signal input devices; the interface of the HDMI display is protected, the problem of bad signal contact resulting from frequent plug is avoided, and the service life of the HDMI display is prolonged; and through setting of a connection switching device, the multi-signal source HDMI display switching is realized, and the multi-signal source HDMI display switching device is convenient for use and reliable in connection.

Description

technical field [0001] The invention relates to a display device, in particular to a multi-signal source HDMI display switching device. Background technique [0002] HDMI, High Definition Multimedia Interface, is a fully digital video and sound transmission interface that can send uncompressed audio and video signals. HDMI is used in equipment such as set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio and televisions. HDMI can send audio and video signals, and audio and video signals use the same cable. [0003] With the continuous iteration of electronic equipment, the interface standards of new and old equipment usually cannot be adjusted immediately. There are still many video interface standards, such as VGA, DVI, DisplayPort, etc., so there are differences in interface standards between old and new equipment and HDMI displays. matching problem.

Problems solved by technology

[0003] With the continuous iteration of electronic equipment, the interface standards of new and old equipment usually cannot be adjusted immediately. There are still many video interface standards, such as VGA, DVI, DisplayPort, etc., so there are differences in interface standards between old and new equipment and HDMI displays. matching problem

At present, the form of adapters is usually used, but when multi-device connections are required, a large number of adapters are required, and at the same time only point-to-point connections can be realized, which brings a lot of inconvenience to users

When you want to switch the signal source, you can only unplug the currently connected signal source and adapter, and then replace the desired signal source and adapter. Not only is the operation troublesome, but frequent plugging and unplugging will cause damage to the connector
