Smartphone Grows, and then Smart Watch?? The shipment of smart phone rises year by year. However, the momentum slows down. Smart watch has become another device with great potential.
From Watch to Smart Watch Function Ecosystem Fashion
Multi-Functions, Worthwile or Worthless? Time Connection with Smartphone Camera Health Athletics Battery Touch Evolving from a device simply displaying time to a gadget connecting all functions Convenient or complicated as it involves with more features?
Ecosystem, Platform a Key Factor Google develops Android Wear and seeks possibilities to run Android on diverse applications by building and optimizing the platform. Google Now is the core to Android Wear Actual and useful information provided at precise time Simple operation and interaction Predict preference and habit Promptly voice response
Ecosystem, Everyone is Looking Forward to Apple Apple Watch uses closed platform and sees potential to lead the market. Apple highly integrates App developments, including heath monitoring and payment functions.
Fashion, Another Factor to Make Purchase Decision Shape: Circular, rectangle Flexible: Flexible substrate Thickness/weight Size: 1.3,1.6, 2.0 Possibility of cross-industry integration
Display Technology Passive matrix TN STN Digital watch/ calculator Active matrix TN VA IPS PDP E-Paper Black/White Color Mainstream technology on display applications Outdated technology on TV application E-reader, e-tag MEMS E-reader PMOLED Mono color display AMOLED Glass Plastic TV, smart phone
TFT-LCD Pros Highly-developed technology Ample capacity Sony Smart Watch Transflective LCD Cons Low panel transparency lifts power consumption Difficult to finish the abnormal shape Moto 360 Abnormal shape LCD
E-Paper Pros Power saving, long standby time E-paper display causes less harm to eyes Pebble Watch E-Paper Black and white Cons Poor color performance Slow screen image shift
MEMS Pros Uses ambient light and no backlight is needed Power saving Full color display Applies both IGZO+MEMS, retaining low energy consumption and improving color performance Cons Cost and yield issues Size constraint Qualcomm Toq Mirasol panel Qualcomm disposes the machinery of its subsidiary QMT and authorizes the MEMS technology to Sharp.
AMOLED Pros Flexible substrate is used Ideal color performance Samsung Gear S Apple Watch Cons Cost and yield issue LG G Watch R ASUS Zenwatch Apple Watch is the 1st product on which Apple uses AMOLED technology and flexible substrate
Comparison of Different Display Technologies Cost Power Color Bend Abnormal Shape STN-LCD Low Low No No - TFT-LCD Medium High Best Yes Yes E-Paper Medium Low Poor - - MEMS High Low Good No - PMOLED Medium Medium Good Yes Yes AMOLED High Medium Best Yes Yes Technologies have both their pros and cons and all see potential on the smart watch application.
LTPS Capacity in Fabs under Gen5 LTPS technology is mainly used on high-end smart phones, and Smart Watch is another possible application.
Smart Watch Forecast from the Supply Side With the entire existing capacity in fabs under Gen5, the output of Smart Watch would exceed 7.5 Billion units.
Smart Watch Forecast from the Demand Side Assumption: ¼ of smartphones are shipped with smart watches
AMOLED is the Potential Technology for Wearable Devices? AMOLED sees more advantages on small-sized and low-resolution devices. The application of flexible substrate expands possibilities for creation and imagination on wearable devices. With P-OLED technology, Apple Watch sees possibilities on various types of designs. Flat Curve Foldable Stretchable
Conclusion The connection function facilitates the data transfer. The implantation of excessive functions is not always valuable. Platform developers play a key role in the build-up of ecosystem. Apple holds potential to create demands. Ecosystem Function The design of wearable device determines the actual sales. Possibilities of cross-industry alliance with watch, consumer electronics, and luxury brands. Different display technologies have their pros and cons on wearable devices. The key is to set up foundation for more possible future usages instead of only digesting capacity. The application of AMOLED technology and flexible substrate brings imagination to wearable devices.
