Flexible Energy Storage: From Supercapacitor to Aqueous Electrolyte Battery

Presentation Abstract:

Our research focuses on development of flexible energy storage/conversion devices, including supercapacitors, batteries and metal air batteries. Here we introduce an extremely safe and wearable solid-state zinc ion battery (ZIB) comprising a novel gelatin and PAM based hierarchical polymer electrolyte (HPE) and an α-MnO2 nanorod/carbon nanotube (CNT) cathode. Benefiting from the well-designed electrolyte and electrodes, the flexible solid-state ZIB delivers a high areal energy density and power density (6.18 mWh cm−2 and 148.2 mW cm−2, respectively), high specific capacity (306 mAh g-1) and excellent cycling stability (97% capacity retention after 1000 cycles at 2772 mA g-1). More importantly, the solid-state ZIB offers high wearability and extreme safety performance over conventional flexible LIBs, and performs very well under various severe conditions, such as being greatly cut, bent, hammered, punctured, sewed, washed in water or even put on fire. In addition, flexible ZIBs were integrated in series to power a commercial smart watch, a wearable pulse senor, and a smart insole, which is the first time that has been achieved to the best of our knowledge.

Presentation Abstract:

Printed electronics has been paid attention for a long time as a technology that changes the rule of the future market. In particular, Printed Electronics technology became more meaningful because many experts and groups are working hard on the technology of Clean, Green and Flexible & Wearable Devices on which all are paying attention. Even though the number of the reports and published papers on the world’s leading technologies for the future tells the great growth, the current level of the technology and markets can not be said to be very positive. For that reason, I will talk about the hidden story of Printed Electronics that would lead the future, which factors are affecting this situation, and a strategic way how to break it through.

High Performance Oxide-Based Diodes and Transistors

 Time: TBD

Presentation Abstract:

Oxide semiconductors have attracted a great deal of interest due to their superior electrical properties compared with conventional thin-film semiconductors, such as high carrier mobility, optical transparency, large-area uniformity and low-processing temperatures. To date, most research on oxide-based devices has focused on material improvements and thin-film transistors, but the effort on diodes is much limited. This is largely because it is difficult to form stable and high-quality Schottky junctions, and oxide semiconductor surfaces and interfaces are very sensitive to process conditions. Like transistor, diode is also a basic building block in most electronic circuits. In many thin-film and/or transparent electronics applications, e.g., radio frequency identification tags, solar cells, amplifiers, and logic gates, high quality Schottky diodes are crucial. Furthermore, Schottky contacts are used in novel transistor structures, such as recently studied oxide-semiconductor-based, metal-semiconductor field-effect transistors. Here, our recent work on high performance oxide-based diodes and transistors is reported. These include very high quality IGZO Schottky diodes with an ideality factor of 1.09, high breakdown voltage, ultra-low noise, and operating speed >20 GHz on glass and 2.45 GHz on flexible substrate. The IGZO-based TFTs also reached a benchmark speed of 1 GHz. These are, to the best of our knowledge, fastest oxide-based diodes and transistors to date. By integrating SnO-based P-type TFTs with IGZO-based n-type TFTs, CMOS-like oxide logic gates and functional circuits are produced, including inverters with a gain up to 150, NAND gate, D-latch, 51 stage ring oscillator and a one-bit full adder, etc.

Recent development of MicroLED displays

Time: TBD

Presentation Abstract:

MicroLED display is believed to be the next generation of flat panel display. The concept of MicroLED display is simple. It can be treated as an LED video wall but shrunk into consumer product sizes with micro-meter scale LED chips as sub-pixel emitting elements. The reasons to develop MicroLED display are lower energy consumption and better reliability. Current LCD is a light absorbing device, which means most of light from backlight unit is wasted and transformed to heat. This will be a big energy crisis while we use more and more displays. OLED seems can reduce some energy consumption as an emissive display, but it is limited by material lifetime and weak environmental reliability. MicroLED could be a good solution by high efficiency and inorganic LED chips. By using PixeLEDTM display technology, we have built a 3.12”, 256×256 pixels, full color MicroLED sample. This sample was built by passive matrix backplane, red, green, and blue MicroLED chips, and a passive matrix OLED driver IC. The sample design parameters and display performance are shown in table 1. MicroLED display is an emerging technology with high brightness, wide color gamut, and high aperture ratio. In additional to traditional display applications, MicroLED display can be used for innovative display technology. Based on our proprietary PixeLEDTM Display technology, we demonstrated a high pixel density display as one possibility of many new applications.

OLCDs on TAC film: Manufacturing and Performance attributes of low temperature OTFT-based LCDs

Time: TBD

Presentation Abstract:

Paul A. Cain

FlexEnable Ltd., 34 Cambridge Science Park, Cambridge, CB4 0FX, UK

OLCDs are a new kind of LCD display built on plastic, made possible by OTFT backplanes, and are shortly entering mass production. Their unique attributes [1] are needed for applications including smart home appliances, notebooks, automotive, TVs and signage, and others where today’s flexible OLED displays are less suited.

 

Flexible OLED displays have many strengths including very high contrast and colour gamut, and are likely to be employed in foldable smartphones in the near future. However, they are expensive to manufacture as a result of both BOM and yield from the complex manufacturing process. Flex OLED display lifetime is also a limitation, particualrly in applications where high brightness is also required [2]. As a result of these attributes, Flex OLEDs are best suited to high value flagship smart phones and smart watches, and these applications will completely dominate use for the next 5+ years. For many other applications that require flexible displays, where large area, low cost, or high brightness with long lifetime is important, a different approach is required.

 

OLCD is a complementary display technology to Flex OLED, making use of existing a:Si TFT-LCD production lines and converting them to manufacture OTFT-LCD onto a TAC film substrate in place of glass. These displays are manufactured with a simple low cost process [3], can be scaled to large sizes, and can be very bright without affecting lifetime (similar to glass LCD). We will describe the process attributes of OLCD, and how the low processing temperature (100°C) results in a low cost process, and allows the best possible optical performance for an LCD, with the added benefits of flexibility, recently demonstrated down to 10mm ROC – a record for LCD displays (see figure 1). We will also how OLCDs will shortly be entering mass production for the first time, in China.

In recent years, growing interest has been focused on developing foldable display for next-generation portable consumer electronic devices. Active-matrix organic light-emitting diodes (AMOLEDs) are regarded as the most promising candidate for foldable display because of the inherent structural advantages [1]. From the perspective of foldable electronics, challenges including structure design, stress control, and reliability issues should be taken into consideration [2]. In particular, the mass production and commercial application of foldable AMOLED display greatly depends on product reliability, such as folding cycles, anti-scratch reliability and impact resistance.

In this work, dynamic bending tests, surface hardness tests, and ball/pen drop tests were studied on a series of 7.2-inch foldable AMOLED display modules, integrating AMOLED panel, polarizer, touch sensor, back plate film, cover film, etc. On the basis of innovative design and optimized processing condition, the display module exhibited good reliability. The 7.2-inch AMOLED display module passed 200,000 repeat folding times with 5mm radius, performed in outward direction. Destructive tests were carried out, and the possible failure modes were analyzed, in combination with simulation results. It was found that stress concentration could either result in film peeling during bending test, or lead to pixel damage while suffered from external impact. Our work sheds light on the reliability issues of foldable AMOLED display module, and we believe foldable smartphones will soon unfold in front of the world.
