The LEDs of OSRAM Opto Semiconductors meet the highest technical standards of Dolby LED backlit professional reference displays. This display is specifically designed for professional production in content production, and is especially suitable for the production and post production of movies and TV series. The Dolby PRM-4200 professional reference display features 1,536 Osram red, green and blue LEDs for a wider color gamut, higher color accuracy, greater dynamic range, and a deeper black order. .
The Dolby PRM-4200 Professional Reference Display is a 42-inch reference display with LED backlights tailored to professional application needs with accurate and realistic color reproduction, extended dynamic range, deep black order and delicate gray Order performance. The LED backlight and Dolby's proprietary dual modulation and calibration technology make this display meet the stringent requirements above. Conventional backlit displays typically use CCFL backlight technology (cold cathode fluorescent lamps), which are difficult to provide pure dark black, often showing only dark gray and narrow color gamut.
Dolby's LEDs are Ceramos MultiLED components from OSRAM Opto Semiconductors, providing the high performance necessary for the professional content creation industry. The red, green and blue chips of the LEDs are carefully arranged, and the color mixing is equally excellent regardless of the angle. With a height of 0.9 mm and an area of ​​3 x 4.5 mm, the LED package is the ideal planar light source. Thanks to the ceramic material, these LEDs are extremely stable over a long period of time and have a service life of more than 50,000 hours.
Winfried Schwedler, Marketing Manager, Osram Opto Semiconductors Germany, said: "We are proud to work with Dolby Laboratories to provide them with high-performance LEDs to meet their demanding applications. Currently, the trend of LED backlights for displays is very high. Obviously; our analysis also shows that more than half of consumer TV sets will be equipped with LED backlights in the next 1-2 years."
