Samsung Develops Three-inch VGA LCD

Samsung Develops Three-inch VGA LCDSamsung announced today it has developed the world’s first three-inch VGA LCD panel that “directly meets industry interface standards for digital still cameras.”  What this means is that future LCD screens on digital cameras will allow multimedia to be viewed at a resolution of 640×480.

In layman’s terms, expect significantly brighter, more detailed LCD displays, which will enable you to review your photography more thoroughly after you take an exposure.  This innovation will make it easier to spot blurry images and ensure your photo is framed properly.

Presently, a majority of camera LCDs only display multimedia at a resolution of 320×240 — significantly lower in quality than Samsung’s new LCD.

An excerpt from Samsung’s official press release:

Executive Vice President Yun Jin-hyuk of Samsung Electronics said, “Our new LCD panel will make viewing of digital pictures distinctly more impressive on camera screens, personal multi-media players and other products requiring high-image resolution and low-power consumption.”

Digital camera makers 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. Manufacturers 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 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 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.

Samsung will start production on the new VGA LCD in 2007. The company plans to exhibit the LCD at IMID 2006 on August 23.

IMID is a a display manufacturing conference held annually in the Republic of Korea.

A 3 inch LCD sounds incredible for viewing digital images in the field but won’t that go through battery power quickly?

Lou: Maybe that’s why they’ve taken care to mention in the quoted press release how many power-saving features are a part of this new LCD?

Call me skeptical, but I’ll want some nice independent tests of the battery’s lifespan with this new LCD and not take Samsung’s word for it. But in any case, with a nice battery grip for my EOS 20D it shouldn’t matter…too much.

Innovation is of bringing things togeather work well. Samsung did it now. Others will too follow and find what better can be done in this technology.

Everyone can claim, i can do it.

But what matters is who has done it.

Congrats Samsung.

Why use R601 interface for digital cameras?

Cathode Ray Tubes have never been a component of any digital camera I have seen. Why would they choose such an obsolete interface standard, which now causes trouble with newer LCD designs?

This seems very short-sighted for an otherwise intelligent and agile industry sector.

Quite a few cameras offer composite video output to a TV monitor, so I can see a rationale behind having the on-board LCD take the same signal, more or less.
