Samsung Electronics has introduced a new range of LED component solutions for use in advanced mobile devices such as smartphones and tablets. The new LEDs for mobile devices include two reflector-integrated flash LED packages: the 3432 1.8t (FH341A) and 3432 1.4t (FH341B), plus a flip-chip flash LED 2016 (FH201A), as well as two side-view LEDs: the 3810 0.6t (MS062F) and 3810 0.8t (MS082F).
These LED products will be showcased at the Mobile World Congress to be held in Barcelona, Spain, later this month. Samsung said that it will start mass producing the new mobile-market LEDs in March, which are likely to then begin appearing in the open market in the second quarter.
“Samsung is becoming an integrated LED component solutions provider that offers highly differentiated value to customers by producing outstanding LED component solutions which are shaping new directions in mobile devices,” said Bangwon Oh, senior vice president, LED strategic marketing team, Samsung Electronics.
Because high-quality smartphone cameras require a wider FOV (Field of View) angle for better picture quality, Samsung’s new reflector-integrated flash LEDs are designed to enable a great deal of flexibility by providing a wide FOV within a small space through the integration of a light source, a lead frame, and a reflector with its own optics and diffusion features.
Of the latest LED mobile offerings, Samsung’s new reflector-integrated flash LED: the 3432 1.8t (FH341A) delivers over 165 lux at 1A and a minimum CRI (Colour Rendering Index) of 80, assuring quality photos in daylight and at night – the3432 1.8t is expected to be used in leading-edge smartphones later this year.
Also new to Samsung’s reflector-integrated flash LED line-up is the 3432 1.4t (FH341B), which has been specifically designed for mobile OEMs seeking extra-slim LED solutions. The 3432 1.4t package includes a reflector and is only 1.4mm thick, a thickness seen as suitable for smartphones and tablets thinner than 7mm. In addition, it provides a minimum illuminance level of 165 lux.
Another addition to the Samsung mobile family, the new standard flash LED 2016 (FH201A) applies Samsung’s proprietary cell-film phosphor technology to flip-chip packages, which applies a thin film of phosphor to each package. Providing for increased design flexibility, the 2016 offers 220lm of light output and improves colour deviation by approximately 40 percent compared to packages using Samsung”s previous technology that dispensed phosphor on each chip. This more affordable LED solution also offers a high level of colour quality, which is rare to traditional flash LED products.
Other new LED packages for mobile applications are Samsung’s Side View LEDs – 3810 0.6t (MS062F) and 3810 0.8t (MS082F), which feature high colour reproducibility, thanks to their high brightness levels. Samsung’s Side View LED packages are also power-efficient, operating on less than 2.9 volts.
Samsung’s 3810 0.6t provides 3.1cd, while coming in at a mere 0.6mm in z-height – ideal for slim smartphones and tablets. The 3810 0.8t offers more luminous intensity at 3.2cd, with a 0.8mm thickness, making it suitable for tablet and notebook PCs.
