ASSEMBLY
• The art of making µLED displays consists in processing a bulk LED substrate into an array of micro-LEDs which are
poised for pick up and transfer to a receiving substrate for integration into heterogeneously integrated system: the
display (which integrates, LEDs, transistors, optics, etc.). Epiwafers can accommodate 100’s of millions of µLED chips
compared to 1000’s with traditional LEDs.
• The micro-LEDs can be picked up and transferred individually, in groups, or as the entire array of 100,000’s of
µLEDs:

TRANSFER FIELDS AND INTERPOSERS
Yield loss = hatched surfaces +
transfer fields where the number n
of KBD and point defects exceeds
specification.
Transfer field with ≥ n point defect
are eliminated.
Transfer directly to backplane or create interposers with transfer fields
that are within the wavelength bin and ≤ n KBD/point defects.
Some bad die are transferred and need to be repaired.
Epiwafer wavelength homogeneity
and defective die map.
If individual functional die testing
not available, use PL + traditional
surface inspection.

DEFECT DENSITY
For the smallest
die required for
TV or
smartphone
applications, the
largest
allowable defect
size will fall
below 1 µm
• The actual specification and the maximum acceptable defect
size will depend on:
• The die size
• The chip structure
• The yield and defect management strategy adopted by each
manufacturer: driven by cost of ownership (cost of increasing
yield vs managing defects)
• A plot of a simple Murphy defect density model with a
triangular distribution shows that to get 90% of 1x1 cm2
transfer fields defect free, the defect density needs be ≤
0.1/cm2.
• For 2x2 cm2 transfer fields, the requirement increases to
<0.03 defect/cm2. Larger stamps quickly lead to unacceptable
wafer yield losses and/or unrealistic demands on defect
density and can only be envisioned if efficient downstream
yield management and repair techniques can be deployed.
• Regarding defect size, abiding by the 1/5th rule used in
semiconductor manufacturing, a 3x3 µm µLED will likely
require ~1 µm features or less, which could be bringing the
acceptable defect size to about 0.2 um. Even if more relaxed
targets are acceptable, 0.5-0.8 µm seems like a reasonable
range.
Above: plot of a simple Murphy defect density model with a
triangular distribution. This model is widely used in the
semiconductor industry for estimating the effect of process defect
density. More complex models should be used to account from
the fact that defects often ten d to appear in clusters etc.

TRANSFER AND ASSEMBLY
• As of Q2-2018, massively parallel pick and place methods are the
most mature, lead by X-Celeprint and Apple with passive (PDMS
stamps) and active (MEMS) transfer head respectively. Various other
companies have demonstrated display prototypes assembled with
similar technologies: XXX, XXX, XXX and probably more who
haven’t publically shown their work.
• Semi-continuous or self assembly processes have also been pitched
and/or demonstrated by a variety of companies including Vuereal
and eLux.
• Semi-continuous process reduce the cycle time by reducing or
eliminating the X-Y print-head motion steps between donor and
receiver substrate (see discussion in the “Cost Analysis” section of
this report).
• Laser transfer potentially offers compelling benefits such as high
throughput and compatibility with KGD yield management
strategies. But development is less advanced than massively parallel
P&P. To our knowledge, glō is so far the only company to have
realized display prototypes using the concept.

EMISSION PATTERN AND COLOR MIXING
• If the red, green and blue emitters have different light emission patterns, the color calibration performed at one angle (typically
perpendicular to the display plane) will shift when viewed off-angle as the relative intensities of R,G,B viewed in that given
direction will changes.
• This issue often occurs when the red emitter is formed from a different material (InGaAlP) and has a different structure than
the green and blue die (InGaN).

Hypothetical beam pattern of Red, Blue and Green emitters (not actual, illustration purpose):

resulting in a shift of color balance at those different angles.

[1]: for all applications, it is assumed that the downconverter is deposited directly at the surface of the pixel (discussion next page). In addition, an overall
optical efficiency of 60% for the red and green pixels and 80% for blue (unconverted) was assumed.
[2]: optimal efficiency with GaN LED is achieved with current density in the 1-10 A/cm2 range. For applications where the required driving current is
significantly below that range, the LED will likely be driven in pulsed mode, ie at higher current density with a low duty cycle

INTRODUCTION
• The different functions required for active display
driving are shared between discrete ICs positioned
at the edges or behind the panel and Thin Film
Transistor (TFT) circuitry deposited directly onto
the display substrate (=backplane).
• Emissive displays such as OLED or microLED are
current-driven. The simplest mode of operation for
the TFT circuit requires 2 transistors and 1 capacitor
(2T1C).
• However, very small variations in current result in
visible brightness differences visible by the human
eye. The 2T1C simple design doesn’t compensate for
pixel to pixel variations in the threshold voltage,
carrier mobility, or series resistance that result from
TFT processing or from variability in the emitters
(LED or OLED)
• Compensation schemes relying on a larger number
of transistors per pixel (up to 7 in some designs) are
therefore used. The complexity of the TFT however
can be reduced in some designs by offloading some
of the compensation function onto external ICs [1].

ILLUSTRATION: 75” 4K TV
• MicroLED makers usually strive to:
• Use the smallest die possible to minimize cost.
• Operate close to peak efficiency in the typical brightness
range of the display.
• For a 75” 4K TV, a 1000 Nits brightness can be

TFTVERSUS DISCRETE MICRO IC.
• Another debate is whether TFT used for OLED panel driving (LTPS for smartphones and wearable, Oxide for TVs) are
suitable for microLED.
• Due to the non linear characteristics of microLED, the different ranges of operating currents and the added complexity
of using 2 types of semiconductors in RGB solutions (InGaN and InGaAlP), driving circuits will likely be more complex
than OLED and integration with traditional TFT be more challenging.
• Apple/Luxvue and X-Celeprint have both suggested using discrete Si-Based microdrivers to drive the pixels. X-
Celeprint has demonstrated multiple display prototypes using this concept.

COST ANALYSIS: INTRODUCTION
• At the current stage of maturation of the
industry, there are still many plausible technology
and process choices. This precludes
comprehensive cost modeling.
• However, there are some fundamentals that
anchor all those processes: alignment dominates
assembly cycle times, die size can’t get infinitely
small, and epitaxy has already been through a
more than 20 years cost reduction curve.
• Basic cost analysis can therefore be performed
to narrow the process space to a more
economically realistic window.
• The objective of this section is to provide such
analyses for the major building blocks and cost
contributors in to order validate the fundamental
economics of microLED displays and identify
credible cost-down paths and targets.
• The effort is focused on the 2 high volume
applications where microLEDs have the most
potential to both disrupt the existing display
chain and generate large, new business
opportunities:TV and Smartphones.
Many unknowns
in term of
technological
choices prevent
detailed cost
modeling but a
high level
analysis can still
provide valuable
insights
By defining cost targets and performing a basic cost analysis within realistic
process parameters, it is possibly to narrow the size of the process windows
compatible with economical targets for each application.

39. MicroLED technology could match or exceed
OLEDs for most key display attributes. However,
it is also an inherently complex technology.
Manufacturing a 4K resolution display implies
assembling and connecting 25 million microLED
chips the size of large bacteria without a single
error, with placement accuracy of 1 µm or less.
This challenge alone appears daunting, but many
others were still seen as potential showstoppers
as recently as early 2017. Eighteen months later,
some assembly technologies are delivering close to
99.99% or 99.999% yields, and small die efficiency
is approaching or exceeding that of OLEDs.
MOCVD reactor suppliers also have credible
roadmaps to deliver tools with the capabilities
and cost ownership that the industry needs. Color
conversion and other aspects are also progressing.
Increasingnumbersofcompaniesaredemonstrating
prototypes. Most are microdisplays on CMOS
backplanes but the number of “large” displays
prototypes is increasing as well, whether they are
using discrete microdrivers like X-Celeprint or
thin-film transistor (TFT) backplanes like AUO
and Playnitride.
Many are still focusing on realizing their first
prototype, but the most advanced have realized
that bringing up the technology from the level of
functioning demo to consumer-grade products
might require more effort than anticipated. Among
others, driving microLEDs is more complex than
OLEDs and using standard low temperature
polysilicon (LTPS) or oxide TFT backplanes might
not be as straightforward as expected.
The report presents a comprehensive analysis of all
critical technology blocks with a focus on the most
recent advancements, emerging options and remaining
challenges.

(Yole Développement, July 2018)
Sony’s demonstration of a full HD 55” microLED
TV at CES 2012, more than six years ago, was the
first exposure for microLED displays and generated
a lot of excitement. Since Apple acquired Luxvue in
2014, many leading companies such as Facebook,
Google, Samsung, LG or Intel have entered the
gameviasizableinternaldevelopments,acquisitions,
like those of mLED and eLux, or investments in
startups such as glō or Aledia.
Analyzing Apple’s microLED patent activity shows
that the company essentially halted its filing around
2015. This is a surprising finding in the light of
the fact that the consumer electronics giant has
maintained a large project team and consistently
spent hundreds of millions of dollars annually on
microLED development. A closer analysis however
brought up the name of a possible strawman entity
used by Apple to continue filing patents and shows
that the company is still advancing key aspects of
microLED technologies.

TECHNOLOGY ADVANCEMENTS PAVE THEWAY FORVARIOUS COST REDUCTION
PATHS TOWARDVOLUME MANUFACTURING, BUT NONE ARE STRAIGHTFORWARD
Dozens of technologies are being developed for
microLED assembly and pixel structures. The cost
and complexity range can be staggering. However,
there are some fundamentals that anchor all those
processes. Alignment dominates assembly cycle
times, die size can’t get infinitely small, epitaxy cost
has already been through more than 20 years on
the cost reduction curve. Cost analysis therefore
allows companies to narrow the process parameters
down to economically realistic windows and identify
efficient cost reduction strategies.
MicroLED companies must understand the cost
targets for each application and work backward,
making process choices and developing each step
so it fits the cost envelope. Processes that can’t
deliver the right economics will disappear. If none
can deliver the right economics, the opportunity
will never materialize. MicroLED is entering the
valley of death between technology development and
industrialization and commercialization.
As the technology improves, there are credible
cost reduction paths for microLED to compete in
the high-end segment of various applications such
as TV, augmented and virtual reality (AR/VR) and
wearables. With the right approaches, assembly cost
could become a minor contributor. For smartphones,
however, approaching OLED cost implies pushing
microLEDs toward what is likely to be the limits
of the technology in term of die size. To succeed,
microLEDs will have to count on some level of price
elasticity. It must deliver performance and features
that no other display technology can offer and that are
perceived by the consumer as highly differentiating.
Microdisplays for AR and head-up displays (HUD)
will be the first commercial applications, followed by
smartwatches. TVs and smartphones could follow
3-5 years from now.
The report features a detailed analysis of the contribution
of die and assembly costs, looking at factors such as die
size, redundancy, yield and assembly strategy for both TV
and smartphone applications.
Despite a later start compared to pioneers such as
Sony or Sharp, Apple’s portfolio is one of the most
complete, comprehensively covering all critical
technologies pertinent to microLEDs. The company is
the most advanced and still one of the best positioned
to bring high volume microLED products to the
market. However, it also faces unique challenges:
• It can’t afford to introduce a product featuring such
a highly differentiating technology that is anything
but flawless.
• It requires high volumes, which makes setting up the
supply chain more challenging than for any other
company.
• It has no prior experience in display manufacturing
and due to its need for secrecy, has to develop
pretty much everything internally, duplicating
technologies and infrastructures that others have
the option to outsource.
The report provides a detailed overview of key players
and analysis the challenges associated with setting up an
efficient microLED display supply chain, including front
end and display assembly.
