LG Display creates world's thinnest large-screen LCD panels, throws future of OLED into doubt

The boffins at LG Display claim to have created the world’s thinnest large-screen LCD panels. Measuring just 5.9mm thin, the 42- and 47in screens employ an edge-lit LED backlight system instead of traditional CCFL (Cold Cathode Fluorescent Lamp).
The company says that its proprietary LGS (Light Guide Sheet) technology has enabled it to reduce the thickness of the Light Guide Plate (LGP) used for LED backlights by more than half.
It’s this LGP which changes the direction of the LED lamps, enabling an even illumination of the panel. The new screens are also half the weight of same size CCFL LCD screens, tipping the scales at just 6.1kg and 7.3kg each respectively.

In a statement, LG Display’s Executive Vice-President Chung In-Jae says: ‘The development of the world’s slimmest LCD TV panel demonstrates our leading edge-lit LED backlight technology that enables thinner designs in addition to our direct-lit type LED backlight assembly which delivers superior picture quality.’
We say: given how amazingly slim these LCD screens are, isn't expensive OLED tech starting to look a little bit redundant?
