Digital posters and information boards are increasingly replacing traditional print – they draw attention with modern design and enable remote content updates. For such solutions to be truly effective, they need displays that not only deliver high image quality but are also readable in daylight and distinguished by low power consumption. In these applications, e-paper is increasingly used. Sharp’s response to these needs is the LP285A6NW01 – a 28.5-inch EPD display matching the standard A2 paper size.

Sharp is a company with over a century of history, specializing in display technologies. With its expertise in TFT matrix design and the use of IGZO technology, the brand remains a leader in information visualization, consistently expanding its portfolio with new solutions, including color e-paper displays.
Features of the LP285A6NW01
The LP285A6NW01 stands out with parameters that make it one of the most advanced e-paper panels in its class. It combines a large format with high readability and low power consumption. The 28.5-inch diagonal corresponds to the A2 format, commonly used for printed posters. This makes the panel an excellent digital equivalent of traditional posters and boards, offering the benefits of an electronic medium: remote, fast content updates, and no need to print new materials. The display operates at a resolution of 2160 × 3060 px, ensuring sharp, detailed images – both for large graphics and small elements (text, logos, QR codes).
The product is based on E Ink’s Spectra 6 technology, which enables content presentation in six colors (white, black, red, green, blue, yellow), significantly expanding design possibilities compared to popular monochrome EPDs.
As with any EPD, the image on Sharp’s LP285A6NW01 is visible in ambient light and does not require backlighting. However, it should be noted that readability in limited lighting conditions requires an additional light source. Like every EPD display, it works in bistable mode – consuming power only when the image changes, which means static content can be displayed for many hours or days with minimal energy consumption. This makes it both cost-effective and environmentally friendly.
A full-screen image change usually takes 15–20 seconds, which is an optimal result for such a large color display. In addition, partial refreshing is possible, allowing faster updates of selected content areas.
The operating temperature range is specified from 0°C to +50°C, so the device is primarily intended for indoor applications; for outdoor use, additional components such as heaters or fans are required to ensure optimal operating conditions.

Structure and Control Technology
The key element of Sharp’s LP285A6NW01 is the TFT matrix based on IGZO technology (Indium–Gallium–Zinc Oxide – an oxide semiconductor technology used in the TFT transistor layer controlling the pixels). Compared to traditional solutions, it offers higher resolution, narrower bezels, and more stable operation with low power consumption. Thanks to IGZO, it is possible to efficiently drive a large, color e-paper display without compromising image quality.
The design uses COF (Chip-on-Film) driver technology – thin, flexible tapes with integrated circuits placed along the edges of the display. They handle pixel lines and transmit signals from the controller to the matrix. The use of COF technology keeps the construction thin and lightweight while maintaining high driving performance.
The central element of the accompanying electronics is the SG-PWB (Source/Gate Printed Wiring Board). It integrates the connections between the matrix and the external system, enabling communication via the mini-LVDS interface. This standard is used in large TFT displays, allowing fast and stable image signal transmission while minimizing electromagnetic interference.
For proper operation, the display also requires an appropriate controller (e.g., E Ink’s T2000 series). It generates the correct electrical waveforms that control the movement of pigment particles in the e-paper layer. As a result, the image is refreshed sequentially and retained without further power consumption. This approach provides great flexibility – the panel can be connected both to simple control modules and advanced content management systems in signage networks.
Applications of the LP285A6NW01
The Sharp LP285A6NW01 is ideal wherever large-format, print-like image aesthetics and energy efficiency are important. Its potential can be fully utilized in areas such as:
- transport – passenger information systems, including electronic timetables and platform/stop signage,
- retail – digital advertising, including POS (Point of Sale) applications,
- smart spaces – information boards in offices and public institutions, urban information systems,
- medical – electronic information boards in hospitals, clinics, and medical centers,
- education – information boards in schools, universities, and libraries,
- culture and art – advertising media in galleries and museums.
