Sony has developed a new technology that will pave the way for the commercialization of an organic electroluminescence (OLED) TV.

The OLED display, used in the OLED TV, uses a material that emits light when voltage is applied, and an organic material is used for the illuminator.

One of the characteristics of the OLED display is a high contrast ratio.

Typically, liquid crystal displays and plasma displays have a contrast ratio of several thousands to one, but the OLED display has a contrast ratio as high as 1 million to one.

The higher the contrast ratio, the more vividly black is displayed.

Called Laser Induced Pattern-wise Sublimation, or LIPS, the latest technology selectively emits 800-nanometer-wavelength laser beams on a donor substrate coated with a light emitting material and placed on a glass substrate, and transfers the light emitting material to necessary parts.

This technology can form patterns without having to use a mask, so it can use low-molecular materials to create large screens.

Sony has already developed a 27-inch OLED TV prototype.

The company plans to ship within the year an 11-inch OLED TV, which does not use the latest LIPS technology but the conventional technology. Sony has not disclosed information on the price and sales volumes.
