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

Embodiment 1

[0024] A display switching device based on multiple HDMI sources, including an HDMI display, at least one signal input source, and a channel controller 7, wherein: the channel controller 7 includes a plurality of switching requests for receiving displays, and the switching The request uses a piezoelectric signal or an infrared signal as a transmission carrier, and is used to connect the selected video input interface with the HDMI display according to the switching request. The channel controller includes a microprocessor and a piezoelectric input device 8 connected thereto, wherein: the signal input source simultaneously transmits a signal to the microprocessor of the channel controller; the piezoelectric input device 8 inputs The channel selection signal is transmitted to the microprocessor; the microprocessor connects the signal input source and the HDMI display according to the channel selection signal; the HDMI display displays the signal of the signal input source in real...

Embodiment 2

[0027] This embodiment makes the following further limitations on the basis of Embodiment 1: the microprocessor is further connected with an infrared receiver for receiving an external wireless input channel selection signal. After the signal is sent by the infrared remote controller, it is received by the infrared receiver connected to the microprocessor, converted into a control command, and the corresponding channel is turned on. The microprocessor is also connected with a digital display device 6 . Display the number of the current channel conduction, which is convenient for checking when wiring errors occur, and also serves as feedback after input. The signal input source is connected to the ARC interface 1 , the MHL interface 2 , the 4Kx2K interface 3 , the PS3 interface 4 , and the HD-DVD interface 5 on the channel controller 7 .

[0028] When in use, different from Embodiment 1, in addition to pressing the piezoelectric input device 8 to select the channel to be conne...

Abstract

The invention discloses a display switching device based on multipath HDMI sources, and relates to the field of display devices. The display switching device comprises an HDMI display and at least onesignal input source, wherein the display switching device further comprises a channel controller, the channel controller comprises a plurality of switching requests for receiving and displaying, theswitching requests use piezoelectric signal or infrared signals as transmission carriers, and the channel controller is used for connecting a selected video input interface and the HDMI display according to the switching requests. The display switching device disclosed by the invention has the characteristics of simple operation, high compatibility and friendliness to different interfaces of new and old signal input devices, meanwhile, the channel controller is deployed to separate the signal input source from the interface of the HDMI display, thereby protecting the interface of the HDMI display, avoiding the problems caused by frequent plugging and unplugging such as poor signal contact or the like, and prolonging the service life of the HDMI display; short-distance wireless control is realized by means of an infrared remote control mode; and the situation of channel conduction is visually displayed in a digital display mode.

Description

technical field [0001] The invention relates to a display device, in particular to a display switching device based on multiple HDMI sources. 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. At present, the form of adapters is usually used, but when mult...
