  • The Wires Remain The Same. Only the Format Has Been Changed (to Confuse the Innocent)

    July 16, 2015

    For the longest time, the pro AV industry was characterized by proprietary cabling formats: One piece of coax with BNCs (or yellow RCA plugs) for composite video. A 15-pin DB9 connector for VGA. DIN connectors for S-video. And RJ-45 plugs for twisted-pair analog signal extenders. With the advent of digital signal interfacing, we’ve got a slew of new connectors that look nothing like their predecessors: The 19-pin HDMI plug. The 20-pin DisplayPort plug. Micro USB. Type-C USB. DVI. And RJ-45 plugs for twisted-pair digital signal extenders. Wait – what? We’re still using RJ-45 plugs, and category wire? Apparently, and we’ve now migrated to the more robust category 6 wire (rated for 1GigE connections); more often than not equipped with shielding to minimize crosstalk and ground wires for longer signal transmission distances. The thing is; we’re now facing a new set of challenges in the way we multiplex and transport video, audio, RS232, IR, USB, metadata, and even power...Read more

  • How Sharp Makes Its “Free-form” Displays

    July 22, 2015

    For some time Sharp has been showing examples of its “free-form” displays, which do both the “row” and “column” driving through the same edge of the display, leaving the rest of the display to be cut in curves or other unusual shapes. But Sharp had not been willing to describe in detail how it distributed the gate drivers throughout the display so that no conventional row drivers mounted on a vertical display edge are necessary. At the most recent SID Display Week held in San Jose in early June, that changed. In the Sharp booth, Automotive Marketing Director for Display Products Thomas Spears did his best to explain the innovation, but it was hard for him to do so in any detail amidst the cut and thrust on the show floor. More detail was available from the invited paper by Hidefumi Yoshida and 13 colleagues from Sharp in Nara, Japan. The paper, “flexible Flat-Panel Display Designs with Gate Driver Circuits Integrated within the Pixel Area,” described Sharp’s truly ..Read more
