Iris Optronics develops Cholesteric Liquid Crystal Display (CHLCD) e-paper technology, offering full-color reflective displays for digital signage, healthcare, and consumer electronics. The technology is manufactured using production lines similar to traditional liquid crystal displays (LCDs), which facilitates scaling and cost reduction as volume production begins. IrisCHLCD holds over 200 patents in CHLCD technology and collaborates with strategic partners including Modern Solid for healthcare distribution and Kent Displays for consumer products.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The CHLCD technology stacks red, green, and blue layers to produce up to 16 million colors, representing a significant color gamut expansion compared to electrophoretic (color E Ink) displays that are limited to 60,000 colors. Because CHLCD operates by controlling liquid crystal states between two glass substrates rather than physically moving pigment capsules, it avoids the color-mixing limitations inherent to ink-based reflective screens, maintaining color accuracy and full-palette reproduction.
For display sizes under 13 inches and up to the 31.5-inch panel shown, IrisCHLCD utilizes a passive matrix driving method. Passive matrix displays require fewer electronics per pixel, resulting in a higher aperture ratio and improved brightness since each pixel can reflect more light. The 31.5-inch passive matrix display features a Full HD resolution of 1920 by 1080 pixels, which maintains large enough individual pixel sizes to optimize reflectivity and brightness in outdoor ambient conditions. Smaller panels in the lineup feature VGA resolutions of 1024 by 768 pixels.
For display sizes exceeding 31.5 inches, including planned panels of 50 inches and larger, the company transitions to an active matrix driving method using thin-film transistors (TFT) on each pixel. Active matrix driving enables updating the entire display area simultaneously in under one second. Active matrix designs can theoretically support frame rates between 10 and 20 frames per second, though operating at higher refresh rates involves a trade-off with the low-power consumption benefits characteristic of bi-stable CHLCD technology.
Target deployments for these reflective displays include digital signage, public transit information boards like bus stops, and healthcare bedside patient monitors. In patient care settings, partner Modern Solid distributes the bedside displays to display medical information. In North America, Kent Displays is preparing to launch a digital photo frame utilizing the CHLCD panels. Volume production of the technology is scheduled to begin at the end of the year.
