ultra low power lcd display manufacturer

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.

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).

E-Paper, also known as electrophoretic display or e-ink, has proven to be one of the most unique display technologies to date. Each E-Paper display is filled with microscopic capsules with different charges to display a wide array of colors (also comes in monochrome). When electrical charges interact with these capsules, it is able to portray and change the display image. Typically images being displayed with E-Paper are stationary and not moving.

The electronic ink charges that portray the images on the displays, appear as if it’s physical paper. The brightness does not change nor fading in any light; even in direct sunlight words on e-paper are still fully readable. E-Paper is considered to be bistable, meaning it only has two states of power; active or inactive. Once an image is projected on E-Paper, it will cease to consume power on the device until you decide to change the image resulting in great battery life.

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.

A lightweight, two-glass design plus an integrated driver in the panel provides an exceptionally thin module. Incorporating the Memory LCD into a design is simple with 3-wire SPI serial interface (SI, SCS, SCK).

Energy efficiency is crucial for future technologies. We need to make our products more power efficient to reduce the stress we put on the environment. Consumers demanding wireless products without bulky cables is another reason to reduce power. Hardware engineers developing IoT projects are struggling to stay within the power budget where the display often is the main problem. To meet these challenges there is a huge demand for ultra-low power IoT displays. In this article, we summarize the three most common low energy displays from a power perspective.

Reflective LCD displays, such as 7 segment displays, have been around for a long time. We recognize them from all kinds of household appliances including thermometers, ovens, watches, toys and medical devices. Until recently, LCD has been the only option for low power but now two alternative technologies exist on the market; the E Ink display based on electrophoresis and the Rdot display based on electrochromism, both offering features that LCD is lacking.

In this article, we investigate E Ink, Reflective LCD and the Rdot Display from a power perspective. All these technologies are categorized as reflective displays. Reflective displays are essentially required for ultra low power applications since emitting light is very power consuming (read more about reflective, transflective, and transmissive displays here). We want to clarify that displays from different manufacturers have slightly different energy consumption, and the data presented here is an average from the suppliers with the most energy efficient displays.

Before we go too deep it is important to understand the driving requirements of each display technology. Reflective LCD displays need an active driver that varies the polarity of the voltage across the pixel in a frequency of about 60Hz. E Ink, on the other hand, doesn"t need any active control once the display has been updated, this feature is often referred to as bistability. Rdot Displays is somewhere in between LCD and E Ink; once the display has been switched the controller can go idle for about 15 minutes (there exist versions that can be idle for up to 24 hours as well). We usually call this phenomenon "semi-bistability". After this time a small refresh pulse is required to maintain the state. For E Ink and Rdot, energy is only required during switching and updating while no energy is consumed during idle state. Typically, the energy required for a full switch on an E Ink display is about 7 to 8mJ/cm2. The corresponding number for the Rdot display is about 1mJ/cm2 with the addition of 0,25mJ/cm2 every 15-60 minutes. LCD continuously consumes about 6µW/cm2.

Followed by the different driving characteristics of the displays, we need to look into how often the display is updated to truly understand which display is the most energy efficient for your specific application. This is done by calculating the average power as a function of the number of switches per day. As seen in the diagram the E Ink display is the most power effective choice if the application is switching less than seven times a day. Between 4 and 600 switches, the Rdot display is the most energy efficient choice. If the display switches more than 600 times a day reflective LCD would be the best option from a power perspective.

To summarize the findings we can conclude that the Rdot display is the most power efficient choice if you need a display that is supposed to switch 4-600 times a day. However, we need to remember that there might be other features to take into consideration as well. For example, the Rdot display is flexible in its standard appearance and can be offered in multiple different colors without additional cost.
