TOPLED Compact 4520 extends the range of TOPLED to provide intense and bright light pulses

The launch OSRAM Opto Semiconductors TOPled Compact 4520 new let super plane display possible. This LED is one of the smallest screen back light source, but also the application of the first use of UX:3 chip technology LED, so is the preferred source for pulse mode, load current can be very high, and contribute to the present extremely realistic picture. More and more flat display requirements of ultra-thin backlight systems and high-quality light, which is the unique attributes of the new TOPLED Compact 4520. This kind of micro light source brightness 35 LM (150mA time) and efficiency 72lm/W, suitable for light from the unilateral or bilateral injection of light guide plate (thickness of up to 2 mm) applications, and can cover more than 100% of the sRGB color gamut. Because of its UX:3 chip has good linear relationship between the current and brightness, so in high current pulsed mode, TOPLED Compact 4520 than all the other chip technology LED is more bright. OSRAM Opto Semiconductors LED backlight German headquarters marketing manager Winfried Schwedler said: "TOPLED Compact 4520 designed for ultra flat panel display design. Its extreme brightness and high current pulse mode helps to render high definition, high contrast screen, and will not produce a wipe effect. By adding black or light to the individual segments of the image, the pulse mode can provide a higher contrast for the dark image, but also can avoid the effect of fast moving image to produce the wiping effect. To achieve this goal, you need to temporarily turn off the backlight. Because the speed is very fast, so that the human eye can not capture the dark phase, so the whole picture appears bright and consistent color. Other members of and TOPLED family, TOPLED Compact also uses 4520 flat package, and not equipped with any lens, so it is very suitable for the light guide plate with unilateral or bilateral injection of light. TOPLED package size tested for 4.5 x 2 x 0.8 mm, high reliability, it can carry out mass production.
