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.

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.

E Ink Holdings announced that it partnered with TPV Technology to launch the first 25.3" E Ink Spectra 3100 color display to the transportation and smart retail markets.

The new E Ink display features four-color technology, with black, white, red, and yellow pigments. When used as transportation signage for railways and buses, it can display alerts and reminders, schedules and changes or other notifications for travel. And when applied in the retail field, it can be used as Point-of-Purchase signage to promotion product information, with vivid reds and yellows to attract consumers' attention.

US-based Solchroma develops a novel reflective inks and actuators based display technology, targeting the outdoor signage market (at least as a first step).

The company introduced its interesting technology at SID Displayweek 2021. The company's CEO, Dr. Roger Diebold was kind enough to explain the company's technology and business to E-Ink-Info.

Hello Roger, thank you for your time. Can you explain Solchroma's ePaper technology?

Solchroma creates reflective digital displays to change how we interact with the built environment and world around us. Solchroma’s technology is based on hydraulically forcing of colored liquid ink in and out of view. A backplane of actuators acts as an array of electrically-controlled pumps that push on nearby reservoirs of ink. Ink reservoirs are shielded from view by a white reflector, while simultaneously allowing passage of ink from the reservoirs behind the reflector to three sealed, viewable chambers stacked one atop the next on the viewable side.

E Ink Holdings has launched an on-cell touch ePaper module, which it says is the world's first. EIH's on-cell touch technology can be applied to the company's E Ink Carta monochrome displays and its Kaleido Plus color displays.

Most e-readers today add a touch layer onto the E Ink display. EIH says that the new technology will increase the contrast ratio by 30% compared to the standard added touch layer solution. For the Kaleido Plus displays, the on-cell will increase color contrast ratio by 40% and the color saturation by 15%. As an added bonus, the on-cell touch solution will be more cost effective and could help reduce eReader prices.

E Ink Holdings launched a new display called E Ink Spectra 3100, which is a next-generation four-color ePaper display aimed to support Electronic Shelf Labels (ESL) and retail signage.

Thew new Spectra 3100 features four-particle electronic ink, in black, white, red and yellow. It features an improved update time, and an expanded temperature range for red and yellow states. Spectra 3100 displays will be offered in panels with an updated all-in-one driver IC that supports premium ESLs with higher resolution across various sizes.

E Ink Holdings officially launched its new color ePaper display, the E Ink Kaleido Plus. The new display technology enables 16-levels of grayscale and 4,096 colors. The new display offers sizes up to 7.8-inch in size (larger than E Ink's first generation Kaleido displays).

E Ink explains that with the new Kaleido display, it has implemented an improved printed color filter array (CFA) technology, with an improved, faster and brighter ink player. These two improvements enable brighter colors with better text rendering.

In 2019 Sony released the DPT-CP1 color Digital Paper A5 device, and now the company is set to release a new version, called (at least for now) the DPT-CP1 Version 2.

The main new feature uses E Ink's upgraded color display (Kaleido 2.5), which features a thinner gap between the display and the color filters which enables the improved performance. The new display features a 1404x1872 resolution and faster refresh.

Plastic Logic's 2.1-inch Legio 240x146 full-color (ACeP) OTFT-driven E Ink display is now available through the ePaper Marketplace.

The display can show four colors (Red, blue, green, yellow plus black and white) and supports a bending radius of 30 mm for the display area and 40 mm for the chip area. The display is suitable for wearables, IoT, and other applications where color, flexibility, ultra low power consumption and a small display are all required.
