Sharp is not a powerhouse electronics company. It was reported this fall to be on the edge of bankruptcy. But even when financially healthy, it has played second or third fiddle, first to Sony and now to Samsung.
But among the big electronics firms at the International Consumer Electronics Show in Las Vegas, it had some of the coolest technology on display.
One theme at this years show was 4K TVs, with most major set-makers and some smaller ones showing off new, ultra-high-resolution sets. Like its rivals, Sharp showed off a full suite of 4K TVs in larger screen sizes. But the company also displayed an 85-inch 8K TV.
Yes, 8K. That means it has twice the number of vertical columns of pixels and twice the number of horizontal rows of pixels as 4K TVs.
While 4K sets are impressive enough in their own right, Sharps 8K is amazing. Despite its large screen size, I had to get within an arms length to start seeing its individual pixels. Even on smaller 4K televisions, you can start seeing their individual pixels farther away than that.
Sharp also had on display two flexible OLEDs, which are manufactured on plastic rather than glass, allowing them to be bent and flexed like a playing card. Both are about the size of a playing card and run full-motion, full-color video.
For someone like me Ive long dreamed of a smart device that I could retract from the side of a pen or roll up and throw in my pocket it was neat to see the technology that might make that possible.
Still, 8K TVs and flexible OLED screens are likely years away from mass market consumer products. So it was exciting to see at Sharps booth demos of a technology that may be in consumers hands much sooner.
That technology is called Igzo. Its a new semiconductor process that uses a combination of indium, gallium, zinc and oxygen (thus the name) in place of silicon. Sharp has started to use it in LCD displays and touch-screen elements.
Igzo transistors can be made smaller than those made of silicon and can move electrons faster. As a result, Igzo screens can be much more power-efficient and Igzo touch screens can be less susceptible to noise, allowing them to more accurately recognize when users touch them. An Igzo display also can hold an image much longer than a silicon-based one before having to be refreshed.
According to Sharp, the power savings can be in the neighborhood of 80 percent to 90 percent better than the standard display technologies. So a smartphone could last two days of typical use before its battery runs out about double the life of todays best smartphones.
