DOWNCONVERTER REQUIREMENTS FOR LIGHTING: CRI
• The Color Rendering Index (CRI) is a measure of howwell a light source reproduces colors compared to areference illuminant.
• The CRI reports a unite-less value between 0 and 100,with 100 being a color reproduction identical to thereference.
• Depending on the color temperature of the observedlight bulb, the reference illuminant is sun light (when thecolor temperature is > 5000 K), or a black radiator(color temperature < 5000 K).
• The difference in color rendition between the sourcebeing evaluated and the reference is measured for 15reference colors. However, the result for only 8 colorsare averaged to obtain the CRI index.
• Because the CRI number is an average between those 8colors, it can give no valuable insight into the rendering ofany specific color. Comparing 2 light sources withidentical CRI of 70, one might render good yellow andpoor red while the other will de the exact opposite.
• Similarly, 2 sources with a very different spectra candeliver a similar CRI (next page).
CRI is an imperfect
indicator of the color rendering ability of a light source. Sources
with very different
characteristic can deliver the same CRI but very different
perception from the user.
Comparisons of 2 sources with same CRI. Note the different
rendering of the blue, yellow and red colors.

PHOSPHOR SHEETS
• Various processes have been developed by different companies to manufacture phosphor sheets. In this process, aphosphor material is embedded in a silicone binder and the mix is laminated or molded into a thin sheet. Typicalthickness varies from XXX to XXX µm.
Just like ceramic
preforms, phosphor
sheets allows for individual chromaticity testing and sorting and
precise matching with various LED
die bins.
• Depending on the mode of application (conformal or preform), full
curing is performed at the sheet level or after binding with the chips.
• Thickness control and uniform dispersion of the phosphor particles
are critical in controlling color uniformity.
• Light scattering particles can be added in order to further improve
color uniformity

MN4+ RED PHOSPHORS: PFS/KFS
GE has granted licenses to Sharp and Nichia for display applications but might keep exclusivity for lighting.
• GE has granted licenses to Nichia and Sharp Corporation. PFS is already used in various commercial displays fromsmartphone, tablets to TV (see Quantum Dot section of this report)
• Ge is also marketing the material for lighting applications under the brand name TriGainTM . The company already usesPFS in some of its own high CRI luminaire showing significant efficiency improvement for high CRI thanks to thenarrow emission band falling almost entirely into the human eye sensitivity curve.

COMPETITIVE LANDSCAPE
• Many of those companies rely on initial expertise developed in thefluorescent lamp phosphor market. Some are affiliates or jointventures with rare earth mining or processing companies (e.g.: XXX,XXX…) and derive cost benefits from access to cheap sources ofYttrium or Lutetium for garnet phosphors.
• Chinese phosphors manufacturers are still mostly focused on thedomestic market. Some of the leading ones such as XXX and XXXare attempting to export their products in Taiwan, Korea and the US.However, exports remain a challenge as very few can offer exclusive,internally developed composition that could be used by LED makerswithout infringing existing IP from their competitors or phosphormanufacturers. However, some LED packagers have secured licensesfrom Nichia for the use of YAG and are free to source the materialfrom whatever supplier they chose.
• As YAG mostly turns into a commodity for tier-2 LED makers, mostcompanies have shifted their focus on higher added valuecompositions such as LuAG, Ga-YAG, nitrides and oxynitrides.
• Chinese vendors offer significantly lower prices and the performanceat some leading players is closing the gap with historical leadersXXX, XXX or XXX. However, there are very large differences inperformance and consistency from one vendor to another.
Quality varies strongly from one vendor to another. But
leading players are closing the
gap with overseas
suppliers while offering
significantly lower prices.

Others:
2014 CHINA VOLUME BREAKDOWN
• We estimate that the LED phosphor market in China was XX metric tons in 2014 (including both on-chip andremote phosphor configurations)
• XXX, XXX, XXX and XXX dominated in volume thanks to large shipment of YAG.
• However, XXX, XXX and XXX dominated in revenue thanks to more favorable product mix comprised of higherASP materials such as LuAG and Nitrides.
Few reliable revenue data
point are available. We estimate that XXX led in
revenue while XXX and
XXX took the lead in
volumes.

15
YAG PRICE TRENDS
• The price of YAG has dropped dramatically in the last 3 years. In some cases, Chinese phosphor suppliers are offeringYAG below cost to lure LED packagers into buying higher added value products such as Nitrides. ASP in China rangebetween $XX to $XX/kg with $XX-$XX/kg typical.
• At those prices, not even the raw materials cost is covered. Suppliers often cut corners by employing lower purityraw materials (3N or less) and eliminating most of the quality controls.
• Outside of China, prices for high quality products from tier-1 vendors can still exceed $XX/kg small volumes and afew $XX’s for larger users.
We expect YAG prices to have essentially bottomed out
as the technology is
now fairly mature and there’s little additional
room for cost reduction

AVERAGE QUANTITY OF PHOSPHOR PER LED• The table below shows our hypothesis for the average quantities of phosphors per mm2 of GaN chip for each conversion
scheme.Those numbers factor in process waste and manufacturing yields.
• In addition, we have considered the following factors:
• Improvements over time in phosphor conversion efficiency (especially for the less mature Nitrides, Oxynitrides, PFS).
• Improvement of the pump efficiency (blue chip): the # of photons delivered per mm2 of chip will increase over time, thereby alsoincreasing the amount of phosphor required to maintain a given color point.
• Various manufacturing losses and LED packaging yields.
• Because of those factors, the quantity of phosphors per mm2 changes in time.

MAJOR COLOR GAMUT IN THE CIE 1931 AND 1976 SPACES
* the ACES AP1 standards make use of “imaginary colors” and pokes out of the color spaces (the ACES AP0 that will be used for encoding features an even broader gamut

QUANTUM DOTS IMPLEMENTATION
Edge (1D) and full surface (2D) configurations.
Due to stability
limitations (High flux,
temperature), QD are
currently used only in remote configurations
• Despite significant progress over the last decade, Quantum dots still suffer from limitations in term stability whenexposed to high flux of blue photons and high temperatures. Those limitations have, so far, prevented QDs frombeing utilized in on-chip configurations.
• For display applications, 2 configurations are currently competing:
Glass tube
with QDBlue LED
Edges:“Color IQ”

Full surface:“QDEF”, “QLAS” etc…

Enhancement Film

21
EDGE VS. FILM: COST STRUCTURE
QDs are not the major contributor to the cost of the remote components.
• At the full component level, we estimate that for a 55” TV produced in large volume, the additional cost resulting fromthe adoption of QD is around $xx for 1D solutions and $xx to $xx for film solutions depending on the backlight type(direct backlit films benefit less from photon recycling compared to edge lighting where the photons travels in the lightguide plate parallel to the plane of the film).
• QD components cost will drop as volume increase and QD performance and manufacturing process improve.Especially, it is expected that new generations of QD less sensitive to oxygen and humidity will be developed. Filmscould therefore been built without the 2 encapsulation barrier layers, allowing significant cost savings.
2D films are more
expensive but more
versatile and easier to
implement.

OLED AND QD DISPLAY COMPARISON
Each technology has fundamental strength and weaknesses
• Ultimately, one can expect OLED to remain superior in term of contrast ratio, viewing angles and response timewhich, on QD-LCD displays, are all limited by the fundamentals of LCD TV designs or materials.
• But continuous LCD TV technology improvements contribute to reducing the gap. Film-compensated multi-domainLC structures, polymer-stabilized blue phase liquid crystal (PS-BPLC [1]) local dimming or edge-lit ultra thin BLU areexample of such improvements. The major remaining challenges for LCD would be response time (best in class arearound 4ms).
• Both OLED and QD-LCD are moving targets. Ultimately cost will decide if both can survive in different marketsegments (entry level for QD / high end for OLED) or if one will eventually dominate the whole TV market.
Both technologies are moving
targets: QD-LCD will strive to improve
performance while OLED will attempt to reduce
cost.
[1]) PS-BPLC nanostructure and short coherence length could lead to LCD response < 1 ms, significantly better than current best in class LCD display at 4 ms
