Embodiment

Embodiment 1

As shown in Figure 1, a kind of transceiver chip, comprise mainboard 1, mainboard 1 is provided with main control module 2, common port 3, radiofrequency signal input interface 4, radiofrequency signal output interface 5, display pannel interface 6, common port 3 is connected with main control module 2, and main control module 2 is connected with display pannel interface 6.

Convert thereof into video pictures by display pannel after common display accepts extraneous vision signal to broadcast, with the use of the effect that could realize the broadcasting of large-screen video pictures after the utility model needs multiple display screen to splice, therefore each flat-panel monitor for splicing, all to carry out cutting process and cascade to the full graphics signal received, make each display can receive the signal needing display.After cutting the complete image signal received, each display only shows

Show a part of image, multiple display splices and combines the complete stitching image of rear formation logic.The size of complete image is the spliced physical size of display unit.

HDCP(High-bandwidthDigitalContentProtection), i.e. HDCP technology.HDTV(HDTV (High-Definition Television)) epoch are coming, in order to adapt to the high bandwidth of HDTV (High-Definition Television), have occurred HDMI.HDMI is a kind of high-definition digital interface standard, and it can provide very high bandwidth, nondestructively transmission digital video and audio signal.In order to ensure that the high definition signal that HDMI or DVI transmits can not illegally be recorded, just there is HDCP technology.HDCP technical specification completes by Intel is leading, and when user carries out bootlegging, this technology can be disturbed, and reduces the quality of the image copying out, thus protects content.Crypto key memory 3-1 is EEPROM, and bandwidth is 25MHz-225MHz, color depth 12BIT, can reach the transmission of 1080P high definition image quality completely.

Video signal input interface 4, radiofrequency signal output interface 5 are connected with common port 3 respectively, and then the cascade function of settling signal.Each display for splicing, its vision signal all passes through common port 3 input and output on display main board 1.N number of display, a N+1 display, N+2 display cascade successively (N is natural number), the picture signal that N number of display radiofrequency signal output interface exports is delivered to the video signal input interface of N+1 display, the picture signal of N+1 display radiofrequency signal output interface output is delivered to the video signal input interface of N+2 display, by that analogy, all stand alone displays of splicing all receive the picture signal needing display.

It is MST6M16 chip that main control module 2 comprises main control chip 2-1, vision signal is delivered to main control chip 2-1 by common port 3, main control chip 2-1 can export after the TMDS signal shaping of source, and the object of shaping guarantees the signal quality of long range propagation and the signal quality of common port.Main control chip 2-1 and the good layout of common port 3 and communication, guarantee the signal quality of long range propagation, therefore can save " the splicing control appliance " that exist in prior art.

Display pannel interface 6 is HDMI, USB interface or AV interface, and the vision signal for the process by main control module 2 delivers to display pannel imaging.

Regular display panel can consume fixing energy, until user changes default.Wait very bright place out of doors, user can improve the brightness of display pannel, to guarantee display effect.When the environment changes, during namely outdoor light intensity decreasing, most of user can't change setting, causes system to be still in high brightness, high power consumption state.Wasting of a lot of electricity will be caused like this.Mainboard 1 is provided with photosensitive module 7, and photosensitive module 7 is connected with main control module 2 by I2C bus, and photosensitive module 7 is high-sensitivity environment optical sensor, and optical sensor described in the utility model is ISL29023 chip.High-sensitivity environment optical sensor, minimum light sensation is low to moderate below 0.015Lux, and dynamic range is up to 64,000Lux, and required operating current is less than 65mA.Described high-sensitivity environment optical sensor carries out exchanges data by I2C bus and main control module 2.Utilize high-sensitivity environment optical sensor, the utility model can the change of automatic detection environmental aspect, by main control module 2, display pannel is adjusted to best brightness, reduces the electric quantity consumption of display entirety.

Mainboard 1 is provided with heat-sensitive module 8, Dynamic controlling radiating module 9, temperature detect switch (TDS) 10, and heat-sensitive module 8, temperature detect switch (TDS) 10 are connected with main control module 2.Heat-sensitive module 8 is can the temperature-sensitive device (as thermistor) of measuring tempeature, and Dynamic controlling radiating module 9 is controlled radiator, and temperature detect switch (TDS) 10 is the control switch of Dynamic controlling radiating module 9.Main control module 2 can monitor the temperature in moment monitor scope at any time by heat-sensitive module 8, when the temperature is changed, the resistance of thermistor can correspondingly change, finally be reflected as the change of chip AD interface voltage, after each AD sampling, temperature detect switch (TDS) 10 controls Dynamic controlling radiating module 9 and opens or cut out.User also can dynamic design temperature threshold value, and when temperature in monitor is higher than preset value, cooling system automatically starts and starts working, and goes round and begins again and does not need manual intervention.Such as, default display is temperature 20-90 DEG C, when ambient temperature be elevated to the temperature threshold 90 DEG C of setting, display interior temperature too high time, main control module 2 opening temp. control switch 10, control Dynamic controlling radiating module 9 and carry out radiating treatment, thus reduce display temperature, when temperature drops to the temperature threshold 20 DEG C of setting, automatic cut out temperature detect switch (TDS) 10, controls Dynamic controlling radiating module 9 and quits work.Go round and begin again, intellectual temperature can be realized and control.
