Note To Readers: While monitoring patent activity is neither novel nor “ground breaking”, it is worthy to note the activity as it applies in certains areas of research with burgeoning interest … such as the application of “nanomaterials” in the OLED/ QLED markets, as being “the next generation display material.”

The quantum dot recently emerged as a next-generation display material. Quantum dots, whose diameter is just a few nanometers, are semiconductor crystals. The smaller its particle is, the more short-wavelength light are emitted; the larger its particle is, the more long-wavelength lights get emitted.
Considering that there are more advantages with the quantum dots over conventional light sources, it is not surprising that the quantum dot display gains a lot of attention. The quantum dot display consumes lower power and has a richer color than the conventional OLED. In addition, the white light produced by quantum dots has high brightness and excellent color reproduction, raising its potential to replace the backlight unit (BLU) using the LED. Not surprisingly, leading companies in the display industry are accelerating to secure relevant technologies.

Analysis of Patent Application Trends By country, 93 patents (or 34%) were filed in South Korea, 87 in the U.S., 36 in Japan, 22 in Europe, and 35 under the PCT. By technology, patents on quantum dot light emitting diodes (QLED) technology (188 patents, 69%) were applied the most, followed by those on BLU using the white light source; quantum dot display; and LED-using white light source technologies.

Implications As the quantum dot display has emerged as the next-generation display technology ever since the OLED, the leading companies in the display industry, including Samsung and LG, are making aggressive investment to take a lead in the technology. They not only develop their own technologies, but also purchase patents from; make technology licensing agreements with; or make equity investment in the companies of the field.

The competition to obtain key patents on the quantum dot display is expected to only increase. Monitoring published/issued patents on a regular basis and having a thorough analysis on them have become more important.

*** Excerpted from: Flexible OLED/ QLED Screen Markets to Reach $72 Billion by 2016

” … Once freed from today’s relatively heavy, breakable and fixed glass displays, tomorrow’s devices may look very different, with screens that can be rolled out, attached to uneven surfaces, or even stretched. But there’s still some way to go.

“It becomes a product designer’s paradise — once the technology is sorted out,” says Jonathan Melnick, who analyzes display technology for Lux Research.

There is no shortage of prototypes. South Korea’s Samsung Electronics this year showed off a display screen that extends from the side of a device — but obstacles remain: overcoming technical issues, figuring out how to mass produce parts cheaply, and coming up with devices compelling enough for gadget buyers.

Screen technology — with the global small display market expected to more than double to around $72 billion by 2016, according to DisplaySearch — is still dominated by liquid crystal displays (LCDs), which require a backlight and sit between two sheets of glass, making the screen a major contributor to the weight of a device, from laptops to tablets.”
