LED TVS: WHAT TO KEEP IN MIND
LEDS ARE LCDS TOO: LED televisions are actually LCD TVs, but with LED backlighting instead of the cheaper and more common CCFL. In LCDs, the backlighting using the fluorescent light strips is more uniform than an LED where the more efficient diodes adjust themselves according to the picture. THE DARK SIDE: This strength of the LED TV is also its biggest weakness. In more of these, the tiny diodes are arranged either along the edges —all four or just two sides. So the parts of the TV farthest from these light-emitting diodes appear darker than the rest of the screen. So most LEDs, at least the cheaper ones, suffer from the problem of uniformity. The costliest TVs have LEDs all across (full-array) the TV and have better uniformity, of course at a price. FRONT FACING: LEDs don’t really solve the biggest drawback of the LCDs, their limited viewing angles. So if you are trying to view the picture from the side of the TV the experience will be far from pleasurable. In fact, some LEDs worsen the problem even though they have better pictures when you are watching from the front. So look for TVs with the best viewing angles. Don’t go by the claims, actually go towards the sides and check for yourself. POWER SAVING, REALLY: LEDs are without doubt more efficient than LCDs. But a CNET survey claims this is at most a 10 per cent saving on power consumption when compared with LCDs. So maybe it’s not nearly a big plus.
