Sony has developed a new technology that will pave the way for the commercialization of an organic electroluminescence (OEL or OLED) TV.
The OEL display, used in the OEL 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 OEL display is a high contrast ratio.
Typically, liquid crystal displays and plasma displays have a contrast ratio of several thousands to one, but the OEL 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 OEL TV prototype.
The company plans to ship within the year an 11-inch OEL TV, which does not use the latest LIPS technology but the conventional technology. Sony has not disclosed information on the price and sales volumes.
