It's been awhile, but earlier this year Hitachi unveiled a beautiful new 4.5-inch IPS LCD sporting 1280 x 720 resolution, a 1,100:1 contrast ratio and a retina display-like 329ppi. Well, in the time since, Hitachi's been hard at work on a virtually identical version of that screen that uses amorphous silicon instead of low-temperature polysilicon (LTPS) as its backplane material. What's the difference? Well, amorphous silicon's much cheaper to produce than LTPS, and the company figured out a way to use it in its new panel with only a scant drop in performance -- the new one's got a lower 1,000:1 contrast ratio, but all the other specs are the same. So, the screen's a comparative bargain while still providing 4.5 inches of 500-nit HD goodness. Thanks, Hitachi, we always did like eating our cake and having it too.
