Good article! The authors claim that the 'edge-lit LED backlighting TV's provide good optical uniformity in screen sizes up to 40"...' but there are many brands that go higher, up to 60" that display reasonably good pictures. Perhaps these larger ones employ more sophisticated light guides? MP Divakar

This technology is growing so fast) 15 years ago I had a lamp TV. 5 years ago I bought a plasma. A year ago I replaced it for a LED Tv. Now what? I will have to buy this new direct backlit system TV? I know it's more efficient. But at the moment I have doubts.. cheap travel insurance

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
