Q. I keep reading about new OLED TVs and new 4K TVs. What's the difference between the two? Is one better than the other? -- Boris, Cleveland, Ohio.

OLED, which stands for organic light-emitting diode, is used to manufacture everything from TVs to computer monitors to even small mobile devices. The OLED display works without a backlight which enables an OLED TV's panel to be ultra-thin. In fact, an early OLED TV from LG is just 0.15 inches thick.

The OLED TV also combines some of the best features of Plasma and LCD sets, displaying deep blacks and high contrast levels. The result is that the OLED TV's eye-popping picture and sleek style is a real dazzler.

The 4K TV, also known as an Ultra HD TV, purports to offers a display resolution four times greater than today's 1080p HDTVs. While many display experts say the 4K picture can not be truly appreciated unless you watch it on a TV 60 inches or larger, industry officials believe the set has the potential of replacing the high-def TV.

The biggest drawback for both 4K and the OLED TV right now is the price. Early 4K TVs can cost up to $40,000 while the first OLED TVs are going for around $10,000 or more.

The OLED TV also is having manufacturing issues. TV makers are struggling to mass produce the set's ultra-thin panels.

If you read the mainstream press, you might think the two TV technologies are in competition with each other. But, actually, they are not. A 4K TV can be an OLED TV, too. In fact, Sony unveiled a
56-inch 4K OLED TV last January at the Consumer Electronics Show, although it may be awhile before it hits retail shelves.
