LG demos 15-inch double-sided LCD
While most manufacturers seem to be working on privacy tech to make LCDs harder to view by anyone not sitting right in front of them, LG is bucking the trend, demoing a prototype that can be read even by those sitting clear over on the back side. Unlike Samsung's tiny double-sided prototype from early last year, LG's shows the same image on both sides, but the 15-inch reflective display's 512 x 384 resolution and 14:1 contrast ratio also reflect just how early this tech is.[Via Hallu Tech]
Samsung unveils "world's first truly double-sided LCD"
They already tout the "world's slimmest" LCD panel for mobile phones, now Samsung is announcing the "world's first" truly double-sided LCD. Samsung's new double-sided LCD can display two entirely different sets of information simultaneously on the front and back of the same screen whereas conventional double-sided LCDs can only show a reverse image of the same data. The magic results from Samsung's new double-gate, thin-film transistor (TFT) architecture. The LCD has two gates -- not one -- which operate each pixel for separate control of the liquid crystal on the transmissive and reflective sides. The 2.22-inch display is 2.6-mm thick and features a QVGA (240x320) resolution, support for 265k colors, and a 250-nit brightness on the transmissive primary screen which drops down to a weak sauce, 100-nit on the secondary reflective screen. Still, thin is in and the new panel can shave a full millimeter off today's dual-panel devices. Hitting the streets in the form of consumable product sometime before July.
