Iphone-4 Retina Display LCD-IPS vs Super AMOLED

Apple introduced the Iphone 4 with LG Displays LCD-TFT Ips Display. Apple calls this “Retina” Display.
iPhone 4 Retina Display is better than OLED says Steve Jobs, we can not believe this!

Here are the Iphone 4 Display details:

• 3.5 inch Display
• 960×640 pixel
• 326 pixel per inch
• 800:1 contrast ratio

Apple about the Retina Display:
The iPhone 4 Retina display uses technology called IPS (in-plane switching) — the same technology used in the Apple LED Cinema Display and iPad — to achieve a wider viewing angle than on typical LCDs. Which means you can hold iPhone 4 almost any way you want and still get a brilliant picture. That’s perfect when you’re sharing photos with a friend or moving your iPhone around while playing a driving or flying game. In addition, the Retina display offers four times the contrast ratio of previous models, so whites are brighter, blacks are darker, and everything is more beautiful.

Update! Samsung says:Apples Retina LCD-IPS cannot catch up with an AMOLED display

Super-Amoled vs Iphone 3GS LCD IPS

A OLED Display does not need a backlight, that does mean that black is black. As you see in the picture the contrast ratio of an IPS LCD Display can not compete with an AMOLED Display. And this problem does also have the Iphone 4 Retina Display.

Super AMOLED offers a better contrast ration then 800:1 OLED does not need a backlight so black is black.
The Super AMOLED is much more better visibillity in sunlight! Samsung suggested that this new Super OLED is five times more vivid than regular and performs 20 percent better when it is used outdoor. So excuse me but with your Iphone 4 the display is not really optimal for outdoor using.

• Samsung Galaxy-S
  4.0inch WVGA(480×800) 16M SUPER AMOLED

• Best outdoor readability
• Wider viewing angle
• No motion blurs on video play
• 100.000:1 contrast ratio
• Longer battery life (no backlight)

The LCD Display on the Iphone 4 is 960×640, 326 ppi resolution and 800:1 contrast ratio, the Super Amoled at the Galaxy S has a resolution of 800×480, 260ppi and a contrast ratio 100.000:1.

The contents used in display are classified as video, graphics, characters. The contrast ratio is the most important factor in video because typically the full video screen was offered about 30 percent of brightness in white base.

The human eye has far superior ability to identify objects in the dark place than in the bright sport. And the human eye can identify the things within certain distance even in the dark places and could not get tired with a long time use in the dark places.
So a high contrast product is much better for the human eye.
