Samsung's 3" LCD Screen for Digital Still Cameras with VGA Quality

Samsung Electronics says it has developed the first 3-inch LCD screen with VGA - 640 x 480 pixels - quality. The new product directly meets industry interface standards for digital still cameras. Digital camera manufacturers use an interface known as ITU-R601 (an international standard for cathode ray tube (CRT) TVs that operates at 30Hz). This standard is incompatible with LCDs, which normally run at 60Hz. Developers have had to reconcile the difference either by compressing the images or by manipulating the signal. However, such approaches will only work with LCDs having a resolution of qVGA - 320 x 240 pixels - or less. Samsung's freshly developed LCD operates on 30Hz, so that allows VGA images to be obtained from a digital camera without having to create another interface.

Samsung's 3-inch VGA LCD display incorporates a dot inversion scheme that lowers power consumption while substantially reducing the image flickering that has prevented such an approach in the past. Power consumption is further reduced because the 30Hz source driver requires less power than the 60Hz type, helping to better differentiate mobile display-based products.
