Ameya360:Powering E-Paper Displays with NFC Energy Harvesting

　　Based on innovative technology, e-paper displays offer significant advantages over traditional displays. Thanks to their unique characteristics, it is not necessary to continuously power the screen; it is sufficient to supply energy when the content of the displayed page is modified. In this way, significant energy savings are obtained, which, in battery-powered applications, translates into greater autonomy.　　Additionally, because power consumption is very low, e-paper displays can be powered through energy-harvesting solutions—for example, by converting the RF energy produced by a near-field communication (NFC) transceiver into electricity. Hence, by combining printed e-paper displays with NFC technology, a new range of battery-less products is enabled.　　In this article, we’ll provide a practical implementation guide on how NFC can be used to power Ynvisible’s e-paper displays.　　Ynvisible e-paper displays　　Ynvisible displays are based on an e-paper technology called Electrochromic Display (ECD), which uses organic electrochromic polymers. Unlike other display technologies that emit light, Ynvisible e-paper devices are categorized as reflective displays, meaning they reflect the ambient light instead of using a backlight. The displays are produced on inexpensive plastic (PET) substrates, making the displays thin and flexible.　　These printed e-paper displays achieve very low power consumption. One square centimeter of active display area requires about 1 mJ to be activated, while the recommended driving voltage is ±1.5 V. That allows Ynvisible’s e-paper displays to achieve the lowest energy consumption on the market for most use cases.　　Additionally, the displays include an image memory (or image retention), which is a crucial component for applications that don’t require batteries. The average image retention duration for Ynvisible’s standard displays is between five and 15 minutes. A brief refresh pulse may be necessary to retain full contrast after this time period, depending on the use case. The displays are manufactured using roll-to-roll screen-printing and lamination processes. They are non-toxic, ITO-free, and mainly comprised of PET plastic. The plastic substrate and roll-to-roll production means thin, flexible, scalable, and highly cost-effective displays.　　Ynvisible also offers a segment e-paper display kit, which allows customers to evaluate the ultra-low–power, thin, and flexible segment e-paper displays. Each e-paper display kit (see below figure) comes with different display designs and includes an e-paper display driver with I2C interface with related user manual.　　Harvesting NFC RF power　　NFC is a short-range data-exchange technology for electronic devices. An inductive pair between two antennas serves as the basis for the communication. NFC does not require that one of the two communicating devices has built-in power, in contrast to many other communication interfaces. Instead, the power transmitted by an NFC reader/writer (such as a smartphone) is harvested to generate power. Contactless payments are NFC’s most typical use case.　　To power an Ynvisible e-paper display with energy harvested from an NFC signal, an antenna and a rectifier diode are required. The power from the antenna will be transferred to the display by inductive coupling between the transceiver and the antenna itself. The signal needs to be rectified with a diode because the display requires direct current. If the display content is intended to fade off quickly after activation, the rectifying diode can be connected in parallel with the display.　　However, if the application requires communicating some data, such as reading an identification code (RFID) or writing data to the device, an NFC chip would be necessary. These chips come in a wide variety of models and vendors, and they each have unique features.　　They fall into three categories:　　1.NFC data storage chips. The transceiver can read and/or write data to the chip　　2.NFC data storage ICs with I2C communication and power output (energy harvesting). These chips can be used to power and/or communicate with an MCU over NFC.　　3.NFC chips with embedded processor. These chips can be thought of as MCUs with NFC capability, which means they have all of the standard MCU functionalities, plus the potential to be powered and/or communicated with via NFC.　　Each of the above IC groups requires a different connection scheme to the display. The following are the most common approaches adopted for implementing the display connection:　　1.Connect in parallel with NFC chip. Following this approach, the NFC chip and the display are connected in parallel. The IC and the display are not directly connected, while the NFC signal powers both the chip and the display. In this scenario, the display will turn on regardless of the transmitted data.　　2.Power output of the NFC chip. If the chip belongs to the second group, the display can be connected directly to the chip’s power output. Similarly to the previous case, the display will turn on regardless of the transmitted data.　　3.MCU in between the NFC chip and the display. Using a host controller in between the chip and the MCU is another method applicable to the second group of chips. Due to the MCU’s ability to read the data from the NFC chip, conditional display driving is made possible. If the user has the authority to read the label, this could be handy when the display needs to be turned on.　　4.Use built-in GPIOs to control the display. This approach is similar to the previous one, but because the MCU capabilities are embedded into the Category 3 NFC chips, no intermediate host controller is needed.　　The power of NFC　　NFC has the potential to replace batteries as the main power source in many applications. From a cost, sustainability, and recyclability perspective, batteries often limit the adoption of electronics and printed intelligence in new applications. Target markets for Ynvisible, its partners, and clients include those for medical technology, smart packaging, smart cards, brand protection, and security gadgets.　　The platform obtained combining NFC and e-paper display technologies can help to create the future of intelligent items, sensors, and other printed electronics.

Global demand growth for flat panel displays to slow

After hitting 7.3 percent growth in 2018, global demand for flat panel displays (FPDs) in terms of area, is forecast to expand 6.4 percent to 228 million square metres in 2019.This will be the first slowdown in year-on-year growth in four years, says IHS Markit.Although the FPD demand will continue to grow, mainly driven by migration to larger displays for major applications, such as TVs, desktop monitors, mobile PCs and smartphones, the pace is expected to slow through 2021.“The uncertainty from rising global trade tension may pose a threat to panel demand,” said Ricky Park, director at IHS Markit. “Huge investment in panel factories in China is also expected to continue to cause oversupply next year.”According to the world economy and global markets report by IHS Markit, world real gross domestic product (GDP) growth is forecast to grow 3.0 percent in 2019, following 3.2 percent in 2018 and 3.3 percent in 2017. The 2019 world real GDP growth was revised down from a 3.4 percent forecast in April 2018 as trade disputes between the United States and China worsened. This will partially contribute to slower growth in end-market demand and the lower demand for FPDs next year.Oversupply is also expected to have an impact as China Star initiates mass production of FPDs from its 10.5th generation fabrication plant (fab) – the world’s second largest – in Shenzhen, China, in the first quarter of 2019.HKC will also contribute to an increase in the production capacity by mass producing panels at its new 8.6th generation fab in the second quarter 2019, IHS Markit adds. As a result, the production capacity of thin-film transistor panels is expected to increase by 11 percent in 2019 compared to 2018, and the supply will surpass demand at a greater magnitude than 2018.“As the market forecast for both demand and supply does not look favourable, panel suppliers and set makers are trying to develop more advanced products and technologies, such as 8K resolution for TVs, quantum-dot organic light-emitting diode (QD OLED) TVs and foldable displays for smartphones and tablet PCs, to bolster consumer demand,” Park said.

Smartphone Displays Set to Move Rapidly to 18:9 and Wider Aspect Ratios in Second Half of 2018

With every smartphone brand applying the 18:9 and wider aspect ratio screens to its newer models, the rate of adoption is expected to quicken in the second half of 2018. Smartphones using 18:9 and wider aspect screens are forecast to increase to 66 percent of total smartphone shipments in the third quarter of 2018, soaring up from 10 percent in the same period last year, according to business information provider IHS Markit (Nasdaq: INFO). After Samsung Electronics and Apple released their phones last year with new wider aspect ratios of 18.5:9 and 19.5:9, respectively, most smartphone brands have similarly followed suit by applying wider aspect screens to their 2018 lineup to keep up with product differentiation.Improvements in display technologies have hastened the expansion of the wider screen adoption in smartphones. Initially, flexible active-matrix organic light-emitting diode (AMOLED) technology was required to realize a full-screen display, and thus, 18:9 or wider screens were expected predominantly to be used in premium and high-end smartphones in 2018. However, with rapidly improving designs in liquid crystal display (LCD) cell structure, thin-film transistor (TFT) array and light-emitting diode (LED) backlight, TFT LCD can now be used in full-screen smartphones.“With the improvement in TFT LCD technology, smartphone makers are now aggressively applying 18:9 aspect ratio of TFT LCD to their 2018 models even for mid-end and entry-level smartphones, instead of using high-priced flexible AMOLED panels,” said Hiroshi Hayase, senior director at IHS Markit.“It would be correct to assume that smartphone displays are undergoing a quick generation change to TFT LCD-based full screens later this year,” Hayase said. “The new generation of smartphones will be expected to stimulate replacement demand in the 2019 smartphone market.”

Smartphones, TVs Drive Surge in AMOLED Displays

　　The value of the global market for active-matrix organic light-emitting diode (AMOLED) panels is expected to reach $25.2 billion in 2017, an increase of 63 percent from 2016, thanks to growing use of AMOLED panels in smartphones and TVs, according to market research firm IHS Markit.　　According to Ricky Park, director of display research at IHS Markit, in addition to smartphones and TVs, the AMOLED panel market will also get a lift from rising demand in  head-mount displays and mobile PCs.　　AMOLED display use has rapidly risen in the smartphone market in particular as the flexible substrate allows phones to be produced in various designs with a lighter and slimmer bodies, IHS Markit said. Leading smartphone makers have competitively rolled out premium phones this year that boast a narrow bezel or nearly bezel-less designs, the firm noted.　　"The AMOLED display market is also expected to get a boost from Apple’s decision to use an AMOLED screen in its iPhone series to be released later this year, and Chinese smartphone makers’ moving to newer applications of AMOLED panels," Park said, in a press statement.　　Park said South Korean and Chinese display makers have been heavily investing in Generation 6 AMOLED fabs in order to increase capacity to meet the surging demand.　　The AMOLED TV panel market, the second largest market for AMOLED displays, is expected to grow to 1.5 million units this year, up from 890,000 units last year, according to IHS Markit's display demand forecast tracker. By 2021, the AMOLED panel market is projected to expand at a compound annual growth rate of 22 percent to exceed $40 billion, IHS Markit predicts.
