Flash LED of Galaxy S5 and More

If you had to describe the back of your mobile device without having to take a look at it, how would you describe it? Among the words you can think of, was flash LED one of them? If you did, we salute you, because flash LEDs are something that a lot of people seem to take for granted. At the MWC 2014, Samsung is showcasing a range of LED component solutions for advanced mobile devices, such as reflector-integrated flash LED packages, flip-chip LED and side-view LEDs. Taking the newest Samsung reflector-integrated flash LED as an example, here are two reasons we should not take flash LED for granted.

First, flash LED plays a big role in determining the quality of photo you take on your mobile device. If you are interested in photography, you have probably heard of the term FOV (Field of view) angle. FOV angle pretty much determines the range of the observable scene that is imaged by a camera. Therefore, for better picture quality, you need a wider FOV angle. Samsung’s new reflector-integrated flash LEDs can provide a wide FOV within a small space with the integration of a light source, a lead frame, and a reflector with its own optics and diffusion features.’

Color Rendering is also a very important factor in taking a great quality photo. Color rendering is the ability of a light source to actualize the colors of objects compared with a natural light source, typically the sun. Therefore, if you want to take great photos regardless of the time of day, you want the flash of your camera to have solid color rendering. The quantitative measurement of the color rending is called the CRI. The sun has a CRI of 100. Samsung’s new reflector-integrated flash LED (3432 1.8t) has a CRI of 80. In fact, the Galaxy S5 uses Samsung’s new reflector-integrated flash LED (3432 1.8t). Yes, it is one of many reasons Galaxy S5 can take such a high quality photos.

A second reason we shouldn’t take flash LED for granted is because it is small. Many people have different preferences for the display size of their mobile devices. However, not a lot of people would prefer thick devices over thin ones. For example, if a new mobile device came out with a bigger display, we are happy (or at least indifferent). But if we were to see a new, thicker device, would we feel the same way? Probably not.  Samsung’s reflector-integrated flash LED (3432 1.4t) is only 1.4mm thick. (Average thickness of a paper ranges 0.05 to 0.1mm) It says that 1.4mm is the thickness ideal for smartphones and tablets thinner than 7mm.

At Booth 2G40, in Hall 2 of MWC 2014, there is much more than the new flash LED products; there are a variety of LED technologies and components that are being showcased. However, considering the effect LED components, such as the flash LED has on the user experience of a mobile device, it sure doesn’t get the recognition it deserves. However, Samsung definitely has a reputation for its extensive investment in LED technology and manufacturing, and it is good to see that Samsung is trying to improve products from various perspectives.
