Sometime I wonder are this component really that expensive. Is the manufacturing try to cashing in on the new product? Cause it is the only way to make big profit before everybody jumping in.
LED LCD is not really new. It been 4yrs in the market and sony is the first to introduce LED LCD in their laptop. Well, maybe we here catchng slow probaly. Because of the price and spending power.
LED LCD have less component and less wattage to generate light compare CCFL. It has thinner LCD too. My Laptop LED LCD only 4mm thick.
One laptop already needs maybe 20~30 LEDs (depends on size) to provide enough back-light, CCFL might only need 2 sticks, 2 little LED might already cost close to 1 CCFL right now so it's still much expensive to produce, not to talk about those monitors and huge size TV.
Less wattage because of the bulb but consider all the components that needs to lights up the panel (yes don't forget that LCD panel also produce light) also consume power, so in the end CCFL still wins in price at the moment, until manufacturer can cheaply produce a bright and durable LED can the monitor makers reduce their cost.
China is catching up on the LED manufacturing, brighter LED but the durability and consistency still lacks, the lifetime still worst than the normal light bulb, so we might expect another few more years before IPS monitor makers fully transition to LED back-light.
