Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
WirelessHD of the present utility model passes the screen multi-media display, comprise the drive plate, liquid crystal display, backlight and the power panel that are installed in the housing, drive plate connects liquid crystal display, power panel connects backlight, backlight connects the backlight of liquid crystal display, and power panel also connects drive plate, and its special character is: the WHDI receiver module that connects drive plate also is installed in the housing, comprise also that in addition the WHDI receiver module also connects power panel be used to the WHDI emission adapter that is inserted on the playback equipment.WHDI emission adapter has a plurality of, is used at most being inserted in four different output devices and selects for switching at any time.The loudspeaker that connects drive plate also is installed in the housing.Housing is provided with regulating key.WirelessHD of the present utility model passes the screen multi-media display, also comprises wired or wireless connections drive plate and can return mouse and/or the keyboard of control output device.
WirelessHD passes the panel type display internal circuit configuration and mainly contains the compositions such as mainboard, power panel, hardboard, liquid crystal display and WHDI receiver module.Each several part performance and effect are as follows:
(1) drive plate (also being mainboard): mainly be to receive the vision signal of coming in order to receive, to process from the outside, comprise the WirelessHD signal that receives by the WHDI receiver module, and send signal by the screen line and go to control the liquid crystal display normal operation.Contain the MCU unit on the drive plate, it is detection control center and the brain of liquid crystal display.
(2) power panel: be used for the alternating voltage of 90～240V is changed into the direct current supply display work of 36V, 18V, 24V 12V, 5V, 3V etc., wherein main improvement is the 5V direct supply part of supplying with the WHDI receiver module.
(3) backlight (also being hardboard): be used for the High Level AC Voltage that DC voltage with 36V, the 24V of mainboard or power panel output, 18V, 12V changes the 1500V～1800V of the high frequency that liquid crystal display needs into, be used for lighting the backlight of liquid crystal display.
(4) liquid crystal display: the liquid crystal display module, it is the core component of LCD TV, it comprises liquid crystal board and driving circuit.
(5) WHDI receiver module: corresponding video source has an emission adapter, and receiver module is used for receiving uncompressed video and the sound signal that the emission adapter sends.
It is to adopt existing 60 ~ 100 cun liquid crystal display products that this WirelessHD passes the screen multi-media display, and introduced the WHDI technical research and formed. WHDI (Wireless Home Digital Interface) (WirelessHD digital interface) agreement, based on global 5GHz frequency spectrum regulation, be operated in 4.9GHz ~ 5.875GHz frequency range, frequency range takies and is about 20M(1080i/720P)-40M(1080P), transfer rate can reach 3Gbps, support the 1080P image without compression, indoor maximum can cover the scope of 30 meters radiuses, and postpone less than 1 millisecond, support the 5.1-7.1 sound channel, the return path of 100Kbps.The WHDI technology has been set a new standard that wireless high-definition degree video connects.It provides a wireless connections mode high-quality, that harmless nothing is compressed.The MIMO technology that it adopts and the modulation system of OFDM can realize the transfer rate up to 3Gbps, and can the synchronous transmission Audio and Video.
Also there are at present the shortcomings such as the higher and power consumption of cost is larger with respect to the wired mode technique, the indoor transmissions scope only is 30 meters, need to patch the WHDI private adapter, along with the development of technology and cost, the WHDI transmitter module will be integrated in the equipment such as notebook.
It is built-in WHDI receiver module and speaker system on the basis of original large-sized monitor that this WirelessHD passes screen multi-media display, the emission adapter that also have outside corresponding with built-in WHDI receiver module, available four at most, realize the random switching of four signal sources.
The emission adapter is small and exquisite flexible, easy to carry.On direct-connected HDMI to signal output apparatus, the VGA interface, plug and play, convenient, flexible.
This WirelessHD passes the screen multi-media display and adopts the high-end widescreen display chip of Mstar a new generation, supports VGA, SVGA, and the multiple display modes such as WXGA+, this scheme display is frequency modulation technology, brightness, contrast, color is more even, shows that the response time is faster.
Advantage of the present utility model:
