Hands On LG’s 55-Inch 55EM9600 OLED HDTV Part II

May 28th, 2012 · 7 Comments · 3D HDTV, News, OLED

In part one we provided price, availability and other marketing information about LG’s upcoming OLED HDTV. We now look into the technical attributes and specifications of this new flat panel television, including a number of exclusive photos and a hands-on view of this revolutionary HDTV.

During a interview with LG’s top marketing people we obtained previously undisclosed technical information revealed below.

Structure

As seen in the photo above the white OLED is made up of a sandwich of blue (B), green(G) and red layers (R), with an overlay of R,G,B filters and a clear section that sends white light to the viewer. LG claims the RGB LED method has problems when scaled to large screen sizes.

Form Factor

As you can see in the photos, the TV’s edges are very thin. The active area ends about one-quarter of an inch from the physical edge of the panel. All three types of mounts use an optical cable between the panel and the electronics as noted in the pole model photo. Each type (pole, wall or table) mount can’t be converted to another mount type as the configuration is part of the 9600’s overall design. (Note: 55EM960V is the model number of the European version of the 55EM9600)

Audio

All three versions include a downward firing speaker section located below the panel. It is said to have multiple drivers though the number was not specified.  We were not given an opportunity to hear the internal speakers. The speakers appear to be permanently mounted and are the same on the wall mount and tabletop versions. (The pole model was not on display).

Technical Specifications

Color- The color gamut is 120% of the HDTV standard called Rec. 709 as outlined in the photo. This accomplished by the colors of the filters used over the white OLEDs and new algorithms that to calculate color and brightness utilizing the fourth (white) sub-pixel. Whether the EM9600 can also provide linear, accurate Rec. 709 reproduction remains to be tested when a review sample becomes available.

Maximum brightness -was specified at 116.475 ft. lamberts (equal to 400 nits). This is brighter than any recent LED LCD we’ve seen or read from other tests (typically 200 to 250 nits with highest around 350). Since the individual pixels can be shut off to zero light emission LG claims an infinite contrast ratio. The extra brightness will also aid the 9600’s passive 3D performance as we expect the brightest 3D images to date.

Refresh-An LG rep stated the refresh rate of the panel is 120 Hz although he did not state if the panel uses motion estimation/ motion compensation or simply frame repeat or the option of both. Regardless, they provided a motion response of 2 one hundred thousandths of a second (.02 milliseconds), which provides full motion response with blurring, adding this is far faster than any LCD by a factor of 100.

Lifespan-When asked about panel lifespan, the marketing executives stated the panels are still undergoing accelerated testing and a specification has not yet been established.

Final Notes

The LG OLED represents the first new flat panel large screen technology in decades. The jet black blacks were easily observed during the demonstrations, regardless of room lighting conditions.  OLED will set new standards for contrast ratio, form factor, image brightness and light weight. We are anxious to learn if this new technology’s color accuracy is adjustable and be able to set new performance benchmarks in this category as well.

Yes, at $10,000 retail this TV is super expensive, but so were large plasma and LCD at time of introduction. No doubt the economy of scale will quickly drive the price down, if large screen OLED technology gains consumer acceptance.
