3M Uniformity Tape improves lighting quality on LED edge-lit LCDs, lowers production costs
Ever seen a display like the one on the left? That's long been a pesky phenomenon -- known as "head-lighting" -- with many LED edge-lit LCD panels, and 3M's new Uniformity Tape wants to make sure it won't be around for much longer. Basically, the tape sticks onto an LCD's internal light guide, and its printed-on optical pattern disperses each LED's light path at wider angles. This allows for up to three times the distance between each LED, while still maintaining an even all-around brightness level across the panel. There are other benefits to this as well considering future LCD panels could use fewer LEDs -- cutting manufacturing costs, and raising eco-friendliness. Hopefully the tape actually ends up working as well as the photo illustrates, but for now, you can view the full press release by clicking past the break.

Checking it out before this film makes its way into the latest LCDs will require a trip to the FPD International show next week in Japan, where the it will also show off film intended for autostereoscopic (no glasses) 3D handhelds, but just a note, tearing off a piece and sticking it on your VIZIO at home won't help, we've tried that.
