Sony Super Top Emission OLED technology

Sony use for their professional monitors BVM-E170 and BVM-E250 the Super-Top Emission technology.

The BVM-E250 will deliver mid April and BVM-E170 will be available in June. At the NAB show in Las Vegas Sony introduce two new cheaper models the PVM-1741 and PVM-2541. Both models offer Full-HD (1080p) support, 89-degrees viewing angle, 10-bit drivers and a 1W mono speaker. Inputs include two 3G-SDI, HDMI, composite and Ethernet.
Sony will sell the PVM-1741 for about 4.900 dollars and the PVM-2531 for about 7.500 dollar. The BVM series costs 15.000, or 30.000 for the larger 25 inch display.

How works Super-Top Emission?

Typical OLED panels use bottom emission. This employs a metal cathode and a chemical desiccant to protect the OLED layer from air and water. It requires the light output to pass through the Thin Film Transistor (TFT) layer, reducing overall output.
Sony’s Super Top Emission™ structure emits light from the other side. This increases light efficiency, achieving higher screen brightness.

Micro-cavities enhance color purity
Like CRT phosphors, the chemistry of OLED emission layers naturally produces Red, Green and Blue light. But Sony goes even further. Red, Green and Blue each have different wavelengths. Sony provides each color with a different emission layer thickness, corresponding to the desired wavelength. These layers, called “micro-cavities” enable light to resonate inside, generating Red, Green and Blue light of substantially higher intensity and purity. In addition, RGB color filters reduce ambient light reflection and further enhance color purity.

Fast motion without blur
Another distinguishing characteristic of Sony’s Super Top Emission OLED panel is incredible response to fast motion. Because the OLED electroluminescent layer is not liquid crystal, it inherently responds to any electrical current input and emits light within millionths of a second. And the panel stays fast, even at low ambient temperatures.

Solid sealing structure
Sony’s Super Top Emission OLED panel is completely sealed by glass substrates, and the electroluminescent layer is wholly isolated from outside air and water.
