Description
Technical field
The present invention relates to the detection equipment technical field of product master control borad, especially relate to a kind of inspection automatically
Survey the method and device of 4K2K product master control borad.
Background technology
Along with multimedia display product image quality is improved constantly by user, the TV such as super large screen, ultra high-definition
Machine is close to our life the most increasingly.Such as Sony, Toshiba, LG, Samsung, Hisense, Haier, wound
The Ge great TV producer both at home and abroad such as dimension, TCL, Konka, Changhong releases the 4K2K of various model this year
The ultra-high-definition television of interface, also Ge great liquid crystal panel manufacturer such as group create photoelectricity, Youda, three
Star, Sharp Corp releases various sizes of 4K2K liquid crystal panel, is applied to various multimedia display and produces
In product, ultra high-definition 4K2K multimedia display product uses the data transfer mode that V-BY-ONE is brand-new
Completing the transmission of super large data volume, the most apparently V-BY-ONE is the development trend of a technology,
Follow-up have more product and do ultra high-definition and show, the most higher resolution ratio.
The new data transfer mode that V-BY-ONE Shi You THine company proposes, similar LVDS, eDP
Or the transmission means of iDP, mainly transmitted by a pair differential signal.
The meaning of V-BY-ONE interface is " video by one ", i.e. transmits LVDS by " single line "
Or TTL signal, popular saying just is the reduction of PCB layout, the especially application on large-size screen monitors, example
Carry out some screens as 4K2K60Hz TV LVDS line needs 96, but carry out some screens with v-by-one line
If, it is only necessary to 18 lines；4K2K120Hz TV LVDS line needs 192 and carrys out some screens,
But if v-by-one line, have only to 34 lines, so can greatly reduce on PCB layout
Problem, but also the interference problem of EMI/EMC can be reduced.
Shown in the composition diagram 1 of 4K2K product, 4K2K multimedia display product is by power module, 4K2K
Product master control borad, 4K2K display floater, voice output, input unit form；Power module is complete
Become to be inputted by outside 110V/220V alternating current and be converted into road required for 4K2K master control borad
12V 5V 3.3V the DC voltage of 24V, be supplied to 4K2K master control borad, 4K2K master control borad can be by
The signal inputs such as various input terminals such as AV, YPBPR, HDMI, TV, SCART or VGA,
After 4K2K decoding process, image section is exported with V-BY-ONE by V-BY-ONE interface
The display floater display image of interface, by voice output output audio signal to loudspeaker power amplifier etc.,
Complete audio signal output, input unit such as touch panel, keyboard, mouse can also be responded simultaneously
Input order performs corresponding function.
At present, for the inspection of band V-BY-ONE interface multimedia display product master control borad (PCBA)
Survey method and detection equipment is: such as with liquid crystal display television core board, the superelevation of V-BY-ONE interface
Clear projecting apparatus machine master control borad, current detection method is that band V-BY-ONE interface product master control borad directly connects
The display screen connecing a band V-BY-ONE interface is identified by artificial naked eyes, and the method is limited to inspection
Survey workman detects duty during product, and therefore testing result exists the biggest subjectivity and fluctuation,
Uniformity is excessively poor, and product quality can not be ensured reliably.The whole production efficiency of the sector at present
Bottleneck in the test side of product, personnel can only be continuously increased at p-wire for this Ge great producer and ensure
Whole product output efficiency and yields；But, owing to recent year labor cost quickly increases,
So certainly will be greatly increased production cost.Multimedia display product industry Ge great producer is all one after another at present
Knock down price to exchange the bigger market share for, it is therefore necessary to release new detection method, can protect
Production efficiency can be greatly improved again on the premise of card product quality.
