  • InfoComm 2017 In The Rear View Mirror

    June 22, 2017

    InfoComm 2017 has come and gone, and left us with lots to think about. For me, this year’s show was hectic, to say the least. I presented my annual Future Trends talk on Tuesday to kick off the Emerging Trends session, then conducted a 3-hour workshop on RF and wireless that afternoon to the largest crowd I’ve ever had for the class. (It may be the largest crowd I ever get as I’m thinking of shelving this class.) Bright and early on Wednesday morning, I taught a 2-hour class  on AV-over-IT (the correct term; you could also use “AV-with-IP”) to a full house. There were even some folks standing in the back of the room. I guessed at least 200 were in attendance. Thursday morning found me back in the same space, talking about 4K and Ultra HDTV to a smaller crowd (maybe not as “hot” a topic?) and urging them to set their BS meters to “high” when they headed to the show floor to talk to manufacturers about 4K-compatible/ready/friendly products. With other prese..Read more

  • Three Premium 2017 LCD-TVs Plot Different Paths to Enhanced Performance

    May 10, 2017

    The white LEDs used in conventional LCD-TV backlight units -- which are actually blue LEDs with a broadband yellow phosphor inside the package -- produce a white light that has insufficient output and purity in the green and red. All current approaches to improving LCD-TV color gamut and purity involve improving the intensity and purity of the red and green light that is produced by the BLU and makes its way to the matrix color filter. Interestingly, three premium 2017 sets now on the market adopt completely different approaches to solving this problem. Samsung's "QLED" Q Series uses a new type of quantum dot (QD) for converting some of the light from the backlight's blue LEDs to red and green. The novelty here is not the architecture of the QD-enhanced backlight, but the design of the Nanosys-developed QDs. Samsung says the QDs are fabricated with a metal alloy and end up with a light-transmissive metal alloy shell. Industry sources say the fabrication process produces "perfectl..Read more
