AM OLED and AM LCD Display Characteristics
AM OLED AM LCD
Thickness/weight Thinner, best is 0.05 mm; lighter Thicker, best is 0.8 mm; heavier
Diagonal Size Limited to small/medium sizes; largest demo is 55"
Can be larger; largest demo is ~100"
Viewing Angle Up to 180° Narrower, depends on liquid crystal type
Color Gamut >100% NTSC (top emission), ~70% NTSC (bottom); high at all gray levels
~70%, up to ~100% NTSC (LED backlight and new color filter); falls at low gray levels
Color Reproduction Better; gamut independent of view angle Good; gamut changes with viewing angle
Resolution Lower; 308 dpi (SM), 202 dpi (polymer) Higher; best is 498 dpi
Response Time Faster, nanoseconds. No motion blur, good for 3D
Slower, milliseconds
Contrast Ratio Higher Lower
Sunlight Readability Better than transmissive LCD, worse than transflective LCD
OK if transflective
Operating Temperature
Range is larger, can operate at low temps like –40°C.
Range is smaller, lowest temp is –10°C.
Power Consumption Lower at typical video content if ~30% of pixels are on
Higher at typical video content
Lifetime Shorter, up to 30K hour, but improving Much longer, above 50K hour
Manufacturing Investment
Lower, but lack of standards keeps the investment only slightly lower
Higher
Production Cost Expensive; low yield, potential to be low cost
Cheaper than AMOLED

Obstacles and Solutions for Large OLED
Obstacles Potential Solutions
Scale to larger back plane a-Si TFT, oxide TFT, etc.
(Tile is another choice, but expensive.)
Color patterning Nozzle printing, LITI, white with color filter, blue
with color change methods
Lifetime
Material improvement, hermetic sealing. Red and
green is more than good enough. Blue still needs
some work.
Cost Improve yield of TFT backplane, material
utilization rate, White with color filter, TAC time
Competing with LCD Flexible/curve form factor, transparent TV?

Comparison of Patterned RGB and White OLED with CF
• LG’s 55” AMOLED TV used white OLED with CF method. • Samsung’s 55” AMOLED TV used RGB.
Advantages Disadvantages
Patterned RGB
(Samsung)
High efficiency Good color
No color filter cost
Yield Cost
Material utilization efficiency Scalability is limited Aperture ratio issues
Differential aging Requires circular polarizer
White with RGBW
Color Filter (LG)
No mask Aperture ratio unaffected Fewer OLED process steps Reduced differential aging
Less color shift Lower voltage
No circular polarizer Higher material utilization
Scalable to large size
Loss of efficiency due to CF absorption
Color gamut a function of white spectrum

Flexible OLED Display • Flexible OLED display has been demoed for several years;
it is easier than flexible LCD, due to solid state. • Samsung will commercialize flexible displays in 2012. LG targets 2013. Sharp
demonstrated flexible AMOLED at SID 2012.

Challenges:
Substrates and encapsulation layer moisture and O2 barrier: plastic, metal foil, ultra-thin glass (<0.1 mm)
Electrode material, TFT material, manufacturing process (bonding/de-bonding, roll-to-roll)
Flexible OLED Display Market Drivers
• iPhone 5 reviews indicated “no wow factor.” The next “wow factor” will come from flexible displays.
• Near term will be fixed/curved, thin, and light weight, but not dynamic bendable.

Summary and Business Strategy Recommendations
• OLED display revenue reached $4B in 2011; DisplaySearch forecast that revenue will surpass $40B by 2019.
• Breakthroughs in oxide TFT and a-Si TFT backplanes and in color patterning are needed for AMOLED to move to larger sizes.
• OLED works in niche applications where LCD cannot compete: » Flexible displays » Transparent displays » Dual view (or even 3 or 4 views) » Lighting
• OLED lighting will reach $6.3B by 2018. » OLED lighting costs need to be reduced and efficiency needs to be improved for mass
adoption.
• Add touch screens
