VGA LCD panel suits DSC industry standards

Samsung LCD panel with VGA resolution

Samsung Electronics Co. Ltd recently announced what it touts as the first three-inch LCD panel with VGA (640 x 480 pixels) resolution that meets industry interface standards for digital still cameras (DSCs).

Digital camera makers use an interface known as ITU-R601, an international standard for CRT TVs that operates at 30Hz. This standard is incompatible with LCDs, which normally run at 60Hz. Manufacturers have had to reconcile the difference either by compressing the images or by manipulating the signal. However, said the press release from Samsung, such approaches will only work with LCDs having a resolution of QVGA (320 x 240 pixels) or less. Samsung's new LCD operates on 30Hz, allowing VGA images to be obtained from a digital camera without having to create another interface.

The three-inch VGA LCD also incorporates a dot inversion scheme that helps lower power consumption while 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, said Samsung.

"This new LCD panel will make viewing of digital pictures distinctly more impressive on camera screens, personal multimedia players and other products requiring high-image resolution and low-power consumption," said Yun Jin-hyuk, executive vice president of Samsung, in a statement.

Samsung will exhibit its LCD panel at IMID 2006, which opens in Daegu, Korea next week. Samsung will begin commercially producing the VGA-resolution LCD panel in the first half of 2007.
