This is a thin, extremely low-power 128x64 graphic LCD display module. It has no backlight, so consumes no power illuminating the display. However, if you wanted to backlight the module, the rear polarizer is transflective, so you could add your own lighting solution there. This display is perfectly suited for hand-held or any application requiring low power consumption or a very thin display. A row of icons is shown automatically top of the display without having to be rendered. This display has an integrated controller and the tail is designed to mate with standard 18-conductor 0.5mm pitch ZIF connectors (typical would be Omron XF2L18351A/ DigiKey P/N OR754CT-ND).

Do you need a display that draws the lowest current possible? Want long lasting battery-powered LCD project? Well, you have come to the right place. We compiled this list of digital displays that consume the least amount of power. These displays are perfect for when you are trying to extend the battery life of your product by pulling the least amount of current possible.

Other than a pen and paper, ePaper provides the lowest power consumption available for electronic displays. It does this via an electrochemical process that requires zero power once the pixels are in their desired location. These displays are ideal for when the content is not updated very often. Low-power ePapers only use power during updates, so the longer time between updates, the lower the power consumed.

The beauty of OLED displays and power consumption is that OLEDs only draw current for pixels that are on. For instance, when displaying a black and white checkerboard pattern, an OLED display consumes 50% less current than when displaying a completely white screen. Keeping that in mind, user interfaces can be designed to conserve as much power as possible by limiting how many pixels are lit.

A low-power display is a display that draws the lowest power possible. It is specifically designed to consume low levels of energy and they are often so-called bistable displays (read more about bistable displays). These displays rely on technologies that allow the device to operate using minimal power inputs and typically only consume energy when the image is changing and no power for static usage. Most, if not all, low power displays are so-called reflective displays. A reflective display is based on the principle of reflection, where light is bounced off the display"s surface rather than transmitted through it. As a result, reflective displays can create an image using only the light available in their environment rather than requiring an external light source, which makes them highly energy-efficient. Read more about reflective displays.

In recent times, there is a growing demand for low-power displays in order to lessen the stress on the environment. Another reason is customers needing wireless products without big power cables or the need for frequent charging. A low-power display is perfect when you try to improve the product"s hours of battery life by drawing the least amount of power possible. A device that uses less power to function is also cheaper to run.

LCDs were the only choice for low power until the arrival of two exciting options into the display market - E-ink display and Electrochromic e-paper display. This article will discuss these three low-power display technologies in brief and compare different features like power consumption, display quality, and more.

Reflective LCDs are prevalent in consumer electronics because of their low power consumption, ease of production, and cost-effectiveness. Low power seven segment display is widely used in calculators, digital clocks, radios, microwave ovens, and washing machines. It works by reflecting ambient light - such as natural light - from a reflective layer back to the viewer.

Electrophoretic display technology (which is used in E-ink displays) has a paper-like ultra contrast appearance that replicates the appearance of ordinary ink on paper. This display technology is popular because of its contrast, readability, thickness, low power consumption, and flexibility. It is widely used in e-readers like Amazon"s Kindle, real-time bus arrival information, electronic shelf label (ESL) segment, menu boards, etc. When the display is electrically charged, charged ink particles rise to the top of the display to create images.

Features:The electrophoretic displays are bistable, meaning they only need energy when there is a change in display. E-Ink display (a specific brand of electrophoretic displays) is the most suitable choice for low-frequency switching, i.e. if the display switches no more than approximately four times in a day.

An electrochromic e-paper display is the best low-power display technology in the market today. These ultra-low-power displays are lightweight, thin, energy-efficient, and cost-effective to produce and operate. They can also be bendable, meaning that they are easily customizable to individual business needs. As a result, these displays are widely used in logistics monitoring, consumer electronics, medical devices, smart cards, and more. Like the LCD, it works by reflecting ambient light. Using electrochromism, when a voltage is applied, the display will change color.

The electrochromic display is the most energy-efficient display technology for medium-frequency switching, i.e. if the display switches between 4-600 times a day.

In terms of display cost, electrochromic displays are among the cheapest technologies both to operate and produce - as they can be produced cheaply using roll-to-roll screen printing.

The design is highly customizable, allowing for a range of design options, including different sizes, shapes, and forms, and it can also easily incorporate a graphic overlay.

Of all the three technologies, only electrochromic displays are bendable. If you need a flexible display then, electrochromic displays are the best option for you.

Ultra-low-power displays consume very little energy, and the two primary technologies used for these types of displays are bistable and low refresh rate displays. They are used when there is a need for a battery-powered device, want maximum life between charges, and the content being displayed does not change very frequently.

The common uses for ultra-low-power displays are e-readers and electronic price tags. Some of the other applications we have seen are secondary displays for handheld devices and battery-powered products like locks, remote-mounted homes, and industrial products.

Probably the most well know bi-stable low-power display is e-paper technology historically used on e-readers. This technology is available in both monochrome and color.

In a monochrome e-paper display, millions of tiny liquid-filled capsules contain black and white charged ink particles. These capsules are sandwiched between a grid of electrodes. Applying a charge to the electrodes causes the ink particles to migrate to the top of the capsule, and depending on the polarity of the charge, it changes the color of the surface of the display.

E-paper is a reflective technology and, with good ambient light, has an excellent contrast ratio. One of the characteristics of e-paper is that the background is white, whereas many reflective display technologies like LCD have a gray or greenish background. One disadvantage is that E-paper requires front lighting if used in low-light conditions.

Displaying static images on an e-paper display uses very little energy (uW). However, it can require more power (mW) to update the screen than other technologies like LCD in the same size and resolution.

The backlight uses most of the power in a standard TFT display. For example, on a 7” TFT panel, the backlight uses almost 80% of the energy consumed for an average brightness display. The digital circuitry utilizes the remaining power to sustain the picture.

The first step of building a low-power TFT is to move to a reflective or transflective display and eliminate the power consumption of the backlight when the display can use ambient light.

Choosing a Transflective display is a good trade-off since it comes with a backlight that, when turned, the display becomes reflective. However, there is some trade-off in that the reflectance of a transflective display is lower than a pure reflective display. We use an advanced LCD driver chip to reduce the power further to drive the display at different refresh rates.

We use an advanced LCD driver chip to reduce the power further, which allows the display to be driven at different refresh rates. The drivers have two modes; a standard TFT mode that enables the display to operate like a standard TFT being able to do video rate, 60Hz, updates, and a low-power mode where the display refreshes at a rate of 1Hz. This mode is excellent for holding static images and using very little energy. Figure 2.0 depicts the driving methodology. Using these drivers, you can reduce the power of the digital portion of the display by 60%.

Table 2.0 shows a comparison study that we did for a thermostat application to compare different low-power technologies. In this study, the display is active for 15 minutes, and then it shows static images for the remainder of the day.

Conclusion: Depending on your application, either low-power TFT or e-paper may be suitable. If power is critical for your application and requires maintaining an image on display for long periods, consider these great technologies.

2. You’re right – the Sharp displays are expensive. Adafruit provides only the display for $45 (which I purchased and used for early prototyping). The NEWT includes the display plus:

That being said… $92 is a lot of money… so I’m all for people building their own – or better yet, building a better version. I’ll add a comment below with links to all the software (device and server side) and hardware designs.

A. I might use a NE555 to send a 1 HZ pulse to the display, and use a different RTC- as long as it was low cost, low power, and supported multiple alarms/timers. Or maybe I’d add a crystal to the ESP32 and use internal RTC (which is super inaccurate w/o an RTC).

C. I think I’d add a legit battery fuel monitor (I use a voltage monitoring chip right now, that goes HIGH when the batt voltage falls below 3.5V). There were few to no LiPO fuel gauge chips in stock when I launched NEWT

PLYMOUTH, Michigan and CHICAGO, Illinois, January 6, 2020 – Kyocera International, Inc. and Azumo today announced a new line of high-performance, extremely low power, reflective liquid-crystal displays (LCDs) illuminated using Azumo’s front light panels.  These LCDs incorporate Kyocera’s Memory-In-Pixel and reflective display technologies combined with Azumo’s front lighting technology to significantly reduce power consumption compared to traditional LCD and OLED displays.  The initial product lineup includes 1.03”, 1.81” and 2.16” displays, and offer excellent options for battery-powered applications including low powered industrial devices, wearable medical devices, Internet-of-Things (IoT) applications, and wearable consumer devices.

Reflective LCDs with MIP act similar to an e-reader (e.g., Kindle) offering an extended battery life, clear visibility in bright sunlight, and high contrast while consuming a minimal amount of power to hold the content on the display.  This new LCD technology achieves low power consumption by incorporating a randomly accessed stored bit in each pixel cell structure, enabling the product designer to address and refresh pixels individually. In addition, Azumo’s low power front light panel only uses one LED and delivers light off the highly reflective display when needed, maintaining low power consumption in dim ambient environments.

Kyocera and Azumo are teaming up to promote this solution to the market.  “These new reflective MIP displays continue Kyocera’s tradition of offering high-quality displays meant for robust industrial, medical and consumer applications,” said Jim Little, General Manager, Kyocera Display Division.  “We are excited to partner with Azumo to incorporate their industry-leading lighting technology for customers that require visibility in all lighting conditions.”

This relationship will enable Kyocera and Azumo to promote lit versions of Kyocera’s display which can be seen both in the dark and in bright sunlight. “We are thrilled to partner with Kyocera for these applications. The combination of their highly reflective LCD with Azumo’s low power front light offers an excellent energy-efficient option for the display industry,” said Mike Casper, CEO of Azumo. “We look forward to expanding these low power display options for tomorrow’s electronic devices.”

Kyocera and Azumo will be showcasing these new displays at the Consumer Electronics Show (CES) in Las Vegas, USA from January 7-10, 2020.  Contact Yulia Kern (ykern@azumotech.com) or Jim Little (Jim.Little@kyocera.com) to schedule an appointment.

LCD stands for liquid crystal display. This display technology uses liquid crystals to form images on the screen which are then made visible through ambient light or a light emitting diode (LED) backlight. Liquid crystal displays are currently the most popular display type on the market. If you have a display on your device, there is a high likelihood that it is a liquid crystal display (LCD).

The Chicago display start-up Azumo just got a vote of confidence from investors, securing $30 million in new financing to drive international expansion, increase manufacturing capabilities and launch new products that use its low-power reflective LCD technology.

“Our LCD 2.0 technology removes the restrictions around how and where we can interact with our devices, and for how long, because it helps displays to sip a fraction of the power and utilize available surrounding light to conserve battery life,” says Mike Casper, CEO of Azumo. “This new financing will allow us to expand sales and applications engineering support globally, grow our international team and continue to deliver on the promises of LCD 2.0 across a variety of industries.”

I did a podcast with Casper about 13 months ago, and described his company’s tech this way: Azumo has developed a micro-thin front light for LCDs, taking the place of the backlighting arrays that illuminate millions or billions of TVs and display monitors. By day, in bright light, an Azumo-equipped display doesn’t even need a light on, front or back. And at night, that front light illuminates the screen.

Right now, Azumo does smaller displays for industrial and medical uses, and is developing the tech for tablets. But the company is equipping its production lines to do larger displays, with the idea that customers like media companies and QSR chains would take a liking to digital posters and drive-thru order screens that didn’t run up big power bills just to be viewable.

Azumo’s technology, says PR, is intrinsically eye safe, extremely thin, and is opening new applications for reflective LCDs across consumer, medical, industrial, and educational markets.

“Azumo is ushering in a new category of display technology, allowing devices with reflective LCDs to work in indoor/outdoor environments, to last longer, and to fit into novel product form factors,”says John Ho, Partner at Anzu Partners, one of the backers.“Since our initial investment, Azumo has solidified its manufacturing and supply chain through a partnership with a leading, global electronics manufacturer, enabling global scale up capabilities and access to new markets.”
