Embodiment
Embodiment below in conjunction with accompanying drawing detailed description the utility model more is expressly understood those skilled in the art and how puts into practice the utility model.Although should be appreciated that to combine its preferred specific embodiments to describe the utility model, these embodiments are intended and being set forth, rather than the scope of restriction the utility model.
As shown in Figure 1; The utility model relates to a kind of flat-panel monitor movement that is used for sliceable formula giant-screen; Comprise mainboard 1; Mainboard 1 is provided with main control module 2, cascade module 3, video signal input interface 4, video signal output interface 5, display pannel interface 6, and cascade module 3 is connected with main control module 2, and main control module 2 is connected with display pannel interface 6.
Common display is accepted to convert thereof into the video pictures broadcast through display pannel after the extraneous vision signal; The utility model needs to be used the effect that could realize that the giant-screen video pictures is play after a plurality of display screen splicings; So each flat-panel monitor that is used to splice; All to carry out cutting process and cascade, make the signal that each display can both receive needs demonstration the full graphics signal that receives.After the complete image signal that receives cut, each display only showed a part of image, and a plurality of displays splice and combine the back and form the complete stitching image of logic.The size of complete image is the spliced physical size of display unit.
Cascade module 3 comprises cascade chip 31 and is used to preserve the crypto key memory 32 of the HDCP key of cascade chip 31.Cascade chip 31 is for accomplishing the chip EP9132 (3) of signal cascade function, and this chip has been integrated the enciphering/deciphering engine, supports HDMI 1.3b and HDCP 1.2 versions.Video signal input interface 4, video signal output interface 5 are all DVI interface or HDMI interface; Cascade chip 31 can input or output DVI, HDMI signal; Also can handle HDCP deciphering and cryptographic operation; Be transformed into the output of two-way DVI/HDMI signal then, the one road to main control chip, and another road is to the cascade chip 31 of display.
HDCP (High-bandwidth Digital Content Protection), i.e. HDCP technology.HDTV (HDTV) epoch are coming, in order to adapt to the high bandwidth of HDTV, HDMI occurred.HDMI is a kind of high-definition digital interface standard, and it can provide very high bandwidth, nondestructively transmission digital video and sound signal.Can illegally do not recorded for the high-resolution signal that guarantees HDMI or DVI transmission, the HDCP technology just occurred.The HDCP technical manual is accomplished by Intel is leading, and when the user carried out bootlegging, this technology can be disturbed, and reduces the quality of the image that duplicates out, thereby content is protected.Cascade chip 31 will use the storer of an outside at the HDCP of this chip key.Crypto key memory 32 is EEPROM, and bandwidth is 25MHz-225MHz, and color depth 12BIT can reach the transmission of 1080P high definition image quality fully.
Video signal input interface 4, video signal output interface 5 are connected with cascade module 3 respectively, specifically, are to be connected with cascade chip 31, and then accomplish the cascading signals function.The display that each is used to splice, its vision signal all pass through cascade module 3 input and output on the display main board 1.N display, a N+1 display, N+2 display cascade successively (N is a natural number); The picture signal of N display video signal output interface output is delivered to the video signal input interface of N+1 display; The picture signal of N+1 display video 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 needs the images displayed signal.
The regular display panel can consume fixing energy, changes default up to the user.Wait very bright place out of doors, the user can improve the brightness of display pannel, to guarantee display effect.When environment change, during promptly outdoor light intensity decreasing, most of users can't change setting, cause system still to be in high brightness, high power consumption state.Will cause wasting of a lot of electric weight like this.Mainboard 1 is provided with photosensitive module 7, and photosensitive module 7 is connected with main control module 2 through the I2C bus, and photosensitive module 7 is the high sensitivity ambient light sensor, and optical sensor described in the utility model is the ISL29023 chip.The high sensitivity ambient light sensor, minimum light sensation is low to moderate below the 0.015Lux, and dynamic range is up to 64,000 Lux, and required working current is less than 65mA.Said high sensitivity ambient light sensor carries out exchanges data through I2C bus and main control module 2.Utilize the high sensitivity ambient light sensor, the utility model is the variation of acquisition environment situation automatically, adjusts to best brightness to display pannel through main control module 2, reduces the whole electric quantity consumption of display.
Mainboard 1 is provided with heat-sensitive module 8, dynamically controls 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 dynamically controlled radiating module 9 and is controlled heating radiator for measuring the thermosensitive device (like thermistor) of temperature, and temperature detect switch (TDS) 10 is a CS of dynamically controlling radiating module 9.Main control module 2 can be at any time through the temperature in the 8 monitoring moment of the heat-sensitive module monitor scope; When temperature variation; Corresponding the changing of resistance meeting of thermistor; Finally be reflected as the variation of chip AD interface voltage, after each AD sampling, temperature detect switch (TDS) 10 controls dynamically control radiating module 9 are opened or are closed.The user is dynamic design temperature threshold value also, and when temperature was higher than preset value in the monitor, cooling system started automatically and starts working, and going round and beginning again does not need manual intervention.For example, preset display is temperature 20-90 ℃, when environment temperature be elevated to 90 ℃ of the temperature thresholds of setting, when the display interior temperature is too high; Main control module 2 is opened temperature detect switch (TDS) 10; Radiating treatment is carried out in control dynamically control radiating module 9, thereby reduces display temperature, when temperature drops to 20 ℃ of the temperature thresholds of setting; Automatically close temperature detect switch (TDS) 10, control dynamically control radiating module 9 quits work.Go round and begin again, can realize intellectual temperature control.
Mainboard 1 is provided with radio receiving transmitting module 11, and wireless receiving module 11 is connected with main control module 2.Radio receiving transmitting module 11 comprises wireless receiving chip and antenna; Be used with the telepilot of outside; Operating personnel can use a teleswitch to send to instruct display is controlled, and the radio receiving transmitting module 11 on the mainboard is accepted instruction and instruction is delivered to main control module 2.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
