COLOR QUALITY METRICS: IES TM-30-15

• TM-30-15, developed by the Illuminating Engineering Society (IES), is a method for evaluating the color rendition

capabilities of a light source. It includes numerous measures that quantify different aspects of color rendering, such

as fidelity and gamut. It incorporates most of the NIST (national Institute of Standards and Technology) previous

work on its “Color Quality Scale (CQS).

• TM-30-15 encompasses several individual measures and graphics that provide a comprehensive characterization of

how the light will affect the color appearance of objects. The three highest-level components of the system are 2

index numbers and a graph:

TM-30-15 can help understand what source will be preferred in a given application. In contrast, the

CIE’s CRI is purely a method for

evaluating color fidelity

Fidelity Index (Rf):

The average of the color difference

between the test and reference conditions.

This is similar to the CRI but over 99 color

samples. The Rf values range from 0 to

100, with 100 indicating an exact match

with the reference.

Gamut Index (Rg):

Measures relative gamut (area enclosed by

the chromaticity of a set of 16 color

samples) and provides information about

saturation. A score >100 means increased

average saturation compared to the

reference source, and a score < 100

indicates decreased average saturation.

Color Vector Graphic:

A visual representation of hue and chroma

shifts for all colors. This graph conveys what

types of colors are more or less saturated

under the tested light source relative to

the reference illuminant. It also shows

where hue shifts occur.

SPECTRAL ENGINEERING

• In the early days of the SSL industry, adjusting the CCT by changing the concentration of the broadband garnet or

silicate yellow phosphors was essentially the only degree of freedom. Today, light source designers have a more

complete toolbox of downconverters and emitters allowing them to create essentially any spectral distribution:

Spectral engineering is the

ability to reproduce any spectral light

distribution to mimic natural or

artificial light sources or create

any unique spectra for a

specific application

Chlorophyll-a:

• Absorption peaks at 430nm and 662nm

• The primary pigment for photosynthesis in plants. Gives plants their green

color (absorbs red and blue). Present in all photosynthetic organisms

except from some bacteria.

Chlorophyll-b:

• Absorption peaks at 453nm and 642nm

• There is usually about half as much chlorophyll-b as the -a variety in plants.

• Exhibits a blue-green visual color. Present in all plants, green algae and some

prokaryotes.

Carotenoids (α/β-Carotene, Lycopene, Xanthophyll):

• Strong absorption between 420nm and 485nm

• Red-orange pigments abundant in plants, fruits, vegetables and whole grains

• Contributes to photosynthesis and protects from excessive light damage.

Other pigments:

• Present in some plants to extend the wavelength range of photosynthesis

to compensate for low light environments or poor use of light.

• Phytochromes (660 and 730 nm peak) : Influence germination, plant growth,

leave building and flowering.

COLOR FILTERS IN TRADITIONAL DISPLAYS

• In traditional LCD

displays, white light

constituted of the 3

primaries emerges from

the liquid crystal cell and

enters the color filters.

• Roughly 2/3rd of that

total light is therefore

absorbed by the filters at

each subpixels, leading to

very low overall

efficiency of an already

optically complex display

stack.

• The overall optical

efficiency of an LCD

display is typically only

about 6%.

In LC displays, about 2/3rd of

the light available after

the first polarizer is lost

in the color filters.

SINGLE CRYSTAL PREFORMS

• Alternatively to ceramic, garnet single crystals (YAG, GaYAG, LuAG…) can also be used for phosphor preform.

• Single crystal have no grain boundaries and therefore exhibit no backscattering and minimized self absorption while

thermal conductivity is maximized.

Single crystal phosphor

preforms further improve thermal performance and reduce scattering

compared to ceramic.

YAG/GaYAG PRICE TRENDS

• YAG prices have dropped

dramatically over the last 5 years. In

some cases, Chinese phosphor

suppliers are offering YAG below

cost to lure LED packagers into

buying higher added value products

such as Nitrides. ASP in China range

between $XXX to $XXX/kg and

contrary to the situation in 2015,

some excellent quality products can

be found in the middle of this range.

• Nevertheless, YAG price can still

reach up to $XXX for highly

customized products with top

performance.

• At the lowest prices, not even the

raw materials cost is covered.

Suppliers often cut corners by

employing lower purity raw

materials (3N or less) and

eliminating most of the quality

controls.

YAG prices have reached

bottom. The technology is

now fairly mature and there’s little

additional room for cost

reduction.

PFS/KSF: INTELLECTUAL PROPERTY

• PFS was developed and patented by GE. Its use has spread rapidly among display makers and as of Q4-2017, GE had

already granted licenses to 18 LED packaging companies for using the material in LEDs for display applications[1].

• The company manufactures and sells its own PFS, but the material is also available from other phosphor manufacturers.

This allows potential users to have multiple sources of material and a broad choice or specifications and prices.

• However, licenses do NOT include use for lighting applications which is strictly restricted to GE own lighting products

A license from GE is required to use PFS in displays. The

material itself is available from

multiple sources.

[1]: the technology is trademarked by GE as “RadiantRed™“.

2017-2022 MATERIAL FAMILY BREAKDOWN

• KSF or other Mn4+ phosphors will increase volume share significantly, however, this value also reflects the fact that

due to its low absorption, PFS quantity in LED packages is typically XX to XX times higher than for nitride.

• Unless performance increases further and cost decrease to levels comparable to YAG, we expect

Key patents held by Nichia and Osram have started expiring in 2017 and will continue to do so in 2018. While both companies have since built on those patents and created broad families of intellectual property (IP), it will become much more difficult for them to prevent competitors from using garnet phosphors in their LED packages.

As a result, phosphor families such as silicates and yellow nitrides (LYSN) are expected to lose market share as LED packagers transition to garnets. The switch will especially affect silicates, which are perceived to have lower performance than yttrium aluminum garnet (YAG) and other garnets, However, some of the most recent silicate compositions developed by tier-1 suppliers are now matching YAG performance but come at a premium price. Leading phosphor suppliers with

a strong focus on silicate materials must therefore diversify their portfolio. They need to create new silicate compositions with unique features to meet specific demands in various high added value lighting applications.

LYSN might fare better in the long term. Yellow nitrides have exhibited steady and continuous performance improvement since entering the market in 2010. The material is already matching garnet performance in most aspects and, being less mature, still offers significant room for improvement. Attractive features of yellow nitride include a lower infrared tail that could translate to higher efficiency compared to YAG. Leaders in nitride phosphors could therefore find a new growth driver as the red nitride market reaches saturation.

(Yole Développement, November 2017)

QUANTUM DOTS HAVE FINALLY TRANSITIONED FROM A SCIENCE PROJECT INTO A BILLION-DOLLAR INDUSTRY AND NEW PHOSPHORS ARE EMERGING

For wide color gamut (WCG) TVs and

monitors, potassium fluorosilicates (PFS/KSF)

and phosphors in general are being challenged

by quantum dots (QDs), which are gaining rapid

acceptance. In 2017, QDs can be found in 47% of

WCG TVs. QDs deliver the best color gamut and

higher efficiency, allowing LCD TV manufacturers

to deliver improved image quality rivaling that of

OLEDs in many regards without having to invest in new fabs.

QDs are therefore set to dominate the rapidly emerging market for high performance WCG TVs and monitors. However, the emergence of a narrow-band green phosphor with the appropriate center wavelength could challenge this dominance and disrupt the market.

PHOSPHORS AND QUANTUM DOTS 2017: LED DOWNCONVERTERS FOR LIGHTING AND DISPLAYS

SATURATING VOLUME AND CONTINUOUS PRICE PRESSURE CREATES A CHALLENGING ENVIRONMENT FOR PHOSPHOR SUPPLIERS.

After five years of cut-throat competition that has driven prices to levels that nobody would have believed sustainable just a few years back, phosphor prices halted their free fall in 2016.

The most mature compositions such as garnets have reached bottom. However, nitride, oxynitride and KSF still have room for significant decline that will offset modest volume growth as the LED market reaches saturation toward the end of the decade.

In this environment, we expect further rationalization of the industry landscape with tier-2 and -3 companies in China exiting the business. Most of those companies don’t have any elements of differentiation, be it on performance or manufacturing cost, that would allow them to survive in this business in the mid- and long-term. However, a handful of domestic players such as Grirem or Yuji Science are emerging as long term credible competitors alongside established leaders such as Intematix and Mitsubishi Chemical.

For most phosphor suppliers, the name of the game is to keep reducing costs as volumes increase and

revenue remain essentially flat. However, the LED industry still has unmet needs in terms of phosphors and new trends and applications such as high CRI lighting and human-centric lighting are generating new demands for efficiency and spectral engineering.

Companies able to develop and commercialize new narrow-band red and, to a lesser extent, green materials could last long-term if they can secure their innovations with strong intellectual property. Other needs, such as good cyan phosphors and red ceramics, could enable more companies, including new entrants, to succeed in this challenging market.

Despite increasing commoditization, the LED phosphor industry therefore still offers opportunities for innovative companies. While price ranges for established compositions will narrow, a significant gap between low end and top performers will persist. This will enable some suppliers to keep capturing significant added value through improved material performance, consistency, ability to deliver highly customized products and strong IP.

QDs have also made significant progress toward “on-chip” configurations. Lumileds and Pacific Light Technology have demonstrated the first commercial grade, high color rendering index (CRI) mid-power LEDs based on high-stability QDs. However, more work is needed to reduce the cadmium content to levels meeting international regulations on heavy metals. The technology could be ready for 2019 but whether or not LED makers will be willing to adopt a downconverter solution containing cadmium will depend on the performance gap that those QD-based LEDs will deliver compared to traditional phosphors.

In displays new phosphor compositions have also rapidly gained market share. After the rise of green silicon aluminum oxygen and nitrogen compounds (SiAlONs), red nitrides are being displaced by PFS which has already captured a 34% share in WCG TVs.
