Abstract
The utility model discloses a HDMI interface auto -change over device, including switching control button, central processing module and HDMI signal switch chip, the switching control button central processing module with the HDMI signal switch chip is consecutive. The utility model discloses directly use the built -in central processing unit quantity performed of display device according to the conversion of information, very big saving cost and manufacture craft, and realized better with display device's combination, when using direct touch screen touch button or use the remote controller can realize that the video source of external equipment switches.
Description
Technical field
The utility model relates to display device technical field, is specifically related to a kind of HDMI switching device shifter.
Background technology
HDMI is often referred to as HDMI (High Definition Multimedia Interface), and be the new interfaces of audio-visual separated transmission in the past of terminating, its maximum transfer speed can reach 5Gb/s, except image data, more can transmit the audio signals up to 8 sound channels simultaneously.The digital data transfer of this uncompressed formula, effectively can reduce signal disturbing and decay that the conversion of number/class causes.HDMI is that first being supported in single cable is transmitted, without the digital interface of the digital high definition of compression, multichannel audio and intelligent format and control command data.
Touching the conversion equipment being badly in need of HDMI in display device.
Utility model content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of HDMI switching device shifter, overcomes prior art and touches the defect of display device without HDMI conversion equipment.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of HDMI switching device shifter, comprise switching controls button, central processing module and HDMI signal switching chip, described switching controls button, described central processing module are connected successively with described HDMI signal switching chip.
According to embodiment of the present utility model, described central processing module is set to Android mainboard.
According to embodiment of the present utility model, described central processing module is set to ops computer.
According to embodiment of the present utility model, described switching controls button is set to touch key-press group or remote controller key group.
According to embodiment of the present utility model, the button of described touch key-press group is set to touch virtual key, and silk-screen at the touch key-press at the touch control device glassy layer back side, or is arranged on the capacitance touch button of frame.
According to embodiment of the present utility model, described HDMI signal switching chip connects described central processing module by HDMI wire or external HDMI.
According to embodiment of the present utility model, described HDMI signal switching chip connects external device by external HDMI, supports that described in multiple stage, external device accesses simultaneously.
According to embodiment of the present utility model, the model of described HDMI signal switching chip is set to AD8191, AD8196 or SIL9533.
The beneficial effect of utility model: the utility model directly applies the conversion that the built-in central processing unit of display device completes data message, cost and manufacture craft are saved greatly, and achieve the combination with display device better, directly the touch key-press of Touch Screen or the video source that can realize external device that uses a teleswitch switch in use.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model HDMI switching device shifter, comprise switching controls button, central processing module and HDMI signal switching chip, switching controls button, central processing module are connected successively with HDMI signal switching chip.According to embodiment of the present utility model, central processing module is set to Android mainboard or ops computer.Switching controls button is set to touch key-press group or remote controller key group.Wherein, the button of touch key-press group is set to touch virtual key, and silk-screen at the touch key-press at the touch control device glassy layer back side, or is arranged on the capacitance touch button of frame.HDMI signal switching chip connects central processing module by HDMI wire or external HDMI.HDMI signal switching chip connects external device by external HDMI, supports that multiple stage external device accesses simultaneously.The model of HDMI signal switching chip is set to AD8191, AD8196 or SIL9533.
As shown in Figure 1, switching controls button can be the button group of the remote controller that display device carries, and central processing module is in the display device built-in, for receiving the key information of remote controller and control HDMI signal switching chip switches external device.
As shown in Figure 2, HDMI switches touch key-press for touching virtual key, and silk-screen at the touch key-press at the back side of touch control device glassy layer, or is arranged on the capacitance touch button of frame.Central processing module is built in touch control device, for receiving touch-control order and being converted into key information (central processing module can be Android mainboard or ops computer).
As shown in Figure 3, HDMI switching switching part comprises: multiple HDMI input port, an output interface, and mcu/IC chip; Wherein one end of output interface is connected with the HDMI access port on touch control device, and the output interface other end is connected with mcu/IC chip, and multiple HDMI input port and mcu/IC chip electrical connect.External device such as pc/PAD etc. is connected with the HDMI input port of HDMI switching device shifter by HDMI wire.
Use procedure: open machine, when touching HDMI touch key-press, touch data information is input to central processing module, receive touch-control order and be modeled as key information, output to process chip by HDMI or HDMI wire, key information is assigned to HDMI by process chip, and correspondence is connected to external device, video data is flowed through HDMI wire by external device, shows the picture of the external device of current connection through process chip and central processing unit on touch display screen; When touching HDMI touch key-press continuously, the switching successively between multiple external device can be realized.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are done, is all contained within interest field of the present utility model.
