New Sony Thin Screens for Mobile Devices Realize CRT-Quality Picture Clarity and Color Gamut

This month, Sony Corporation will commence mass production of a full-color Organic Light Emitting Diode (hereafter OLED) display, which will be first implemented in the new Sony CLIE 'PEG-VZ90' personal entertainment handheld (also announced today for the Japanese market).

About OLED:
OLED or Organic LED is not made of semiconductors. It's made from carbon-based molecules. That is the key science factor that leads to potentially eliminating LEDs' biggest drawback – size. The carbon-based molecules are much smaller. And according to a paper written by Dr. Uwe Hoffmann, Dr. Jutta Trube and Andreas Klöppel, entitled OLED - A bright new idea for flat panel displays "OLED is brighter, thinner, lighter, and faster than the normal liquid crystal (LCD) display in use today. They also need less power to run, offer higher contrast, look just as bright from all viewing angles and are - potentially - a lot cheaper to produce than LCD screens."

OLED display is a self-luminous display that does not require a back-light, offering high contrast ratio, a quick response time and wide viewing angle-all in a package slimmer than current LCD modules. To enhance this display, Sony has employed its unique Super Top Emission technology for outstanding brightness and greater color gamut. These translate into image quality and clarity that could previously viewed only on CRT (cathode ray tube) displays.

The new 3.8-inch (or 9.7 cm) screen measures 2.14 mm thin, and makes it possible for users to enjoy a variety of high-quality content such as TV programs and digital still images on mobiles products such as the new CLIE VZ90 handheld without compromising on the viewing experience.

Key Features

1.Super Top Emission
As the name implies, Super Top Emission leads light emission from the upper side of the organic material, realizing a brightness level of 150cd per square meter. Also, by optimizing the thickness of the organic layer for each of the color components, RGB, Sony realized multi-interference of reflecting light. Additionally, with the cavity multi-reflection interference structure which enables emission of colors with high purity, bright and brilliant color gamut comparable to that of CRT is realized

2.Excellence in response time, viewing angle and contrast ratio
As OLED works with self-luminous organic materials, it has outstanding response time, without producing any afterimage even when displaying moving images (movies). Also with wide viewing angle and contrast ratio as high as 1000:1, high quality images can be realized on mobile products which are used in various occasions.
