The evolution of outdoor digital displays continues to transform cities around the globe, and change the way we interact - from transportation to retail shops, hospitality, real estate, construction, education and entertainment.

Increasingly, we are seeing digital outdoor displays such as signs on buildings, train stations, bus stops, parking meters, gas stations and ATMs. In the past couple of decades, large format LED displays have dominated the outdoor display applications.  Two display technologies that have begun to grow significantly for outdoor use are LCD (liquid crystal display) and ePaper. Below, we look at the growth and innovation of both, as well as design and function challenges, and what to expect in the future.

AU Optronics demonstrated a new 7.9-inch display, that utilizes the company's new reflective LCD display technology, called ChLC - cholesteric liquid crystal technology.

The display can cut the driving voltage when the display is static, and does not have any backlight. This reduces the power consumption of the display, which also does not use any color filters or polarizers and so offers higher reflectivity and color saturation compared to E Ink displays.

E Ink announced its latest color ePaper display, the Gallery 3, targeting applications in eReaders and Notes devices.

The Gallery 3 is based on E Ink's ACeP (Advanced Color ePaper) platform, where a full-color gamut is achieved through a four particle ink system: cyan, magenta, yellow and white, which allows a full color gamut at each pixel. Gallery 3 displays offers a faster refresh rate (350 ms for black and white, 500-1500 ms for color refresh), a substantial improvement over the first generation E Ink Gallery (which offers a black and white update in 2 seconds, and full-color in up to 10 seconds).

E Ink announced a new display type, called the E Ink Spectra 3100 Plus, which is a five-color ePaper aimed towards retail applications. The new displays support black, white, red, yellow and orange colors. This display is an enhancement of E Ink's current four-color Spectra 3100 ePaper, adding the new orange color.

E Ink will produce the Spectra 3100 Plus displays in a variety of sizes, including 1.64-inch, 2.36-inch, 3-inch, 4.37-inch, 7.3-inch and 8.14-inch.

E Ink announced that it is seeing increased demand for color ePaper displays, and it is working with six module production partners to promote its color (ACeP) displays and to increase production capacities of its Gallery Palette and Gallery plus panels.

The six partners are BOE Technology, DKE, Jiangxi Xing Tai Technology, Innolux Corporation, Qingyue Technology, and Yes Optoelectronics. E Ink supplies the color ePaper frontplane materials while the module makers manufacture the color ePaper modules in various sizes and shapes.

Exevio developed a new signage solution for EV charging stations, that is used to direct drivers to available charging locations. The idea is to deploy the signs at critical intersections, parking entrances and other places to help drivers find an available charging station.

The new signage is based on Ynvisible's ePaper display technology.

E Ink launched its latest color ePaper display, the Kaleido 3, with richer colors. E Ink says that the Kaleido3 improves the color saturation by 30% compared the previous-generation Kaleido Plus (which was launched in March 2021).

The Kaleido 3 display is based on E Ink's Print Color ePaper technology, where a color filter array (CFA) is used in conjunction with E Ink’s Carta black and white ink film. The Kaleido 3 also implements E Ink's new ComfortGaze front light technology. ComfortGaze has been engineered to reduce the amount of blue light reflected off the surface of the display, providing further comfort while reading with reduced Blue Light Ratio (BLR) and Blue Light Toxicity Factor (BLTF) by up to 60% and 24% respectively compared to the previous generation of front light design.

E Ink announced a new generation of its Advanced Color ePaper (ACeP) display, called the E Ink Gallery Plus. This full color display offers an improved contrast ratio and color gamut compared to the previous generation displays. E Ink targets commercial signage for these displays - such as retail, restaurants, transportation and public information displays.

E Ink says that the Gallery Plus displays, based on the ACeP platform, is a full-color electronic ink system with four color pigments: cyan, magenta, yellow, and white. The contrast ratio is improved by 40% (from 10 to 14). E Ink Gallery Plus will be available in various sizes for customers, including 13.3-inch, 25.3-inch, and 28-inch.
