2.9 Inch E Paper Module 128×296 Resolution 24pin Ultra Low Power 3 Colour E Ink Display

The YE029A241 excels in medium-size color-coded scenarios with its 112 DPI display and 3-color capability. It vividly presents classified information—red for promotions/urgent alerts, black for text, and white for background—making it perfect for electronic shelf labels, smart wearables, and portable terminals. Its pixel pitch (0.226×0.227mm) ensures sharp text and barcodes, even small fonts remain legible. The hard-coat antiglare surface eliminates glare under direct sunlight, maintaining readability in retail stores or outdoor kiosks. With an ultra-thin (0.9mm) and lightweight (5.098±0.5g) design, it fits into space-constrained devices like smart labels, while ultra-low power consumption (≤3μA deep sleep) enables over 12 months of battery life for daily-updated applications.

The YE029A241 is mainly designed for Electronic Shelf Label (ESL) systems, with diverse industry applications. In retail, it serves as standard electronic shelf labels for groceries, electronics, and more, using 3-color display to highlight promotions (red), product names/prices (black), and stock status (white background)—enhancing customer information access and reducing manual update costs. In logistics, it functions as cargo tags, displaying waybills and statuses with red for urgent shipments, withstanding -25~60℃ transportation for 10 days. In smart wearables, its compact size fits into fitness trackers or smart badges, showing steps, heart rate, or alert notifications. With ROHS2.0+HF+REACH compliance and rigorous reliability testing (high/low temperature, humidity, vibration, ESD), it meets global environmental and reliability demands.

The YE029A241 features 128×296 resolution (112 DPI) with 0.226×0.227mm pixels, delivering sharp text, barcodes, and 3-color graphics. Its color performance is precise: red state L*=25~26.5 (a*=38~40), white state L*=64~65, and black state L*=11~14. The high contrast ratio (white reflectance divided by dark reflectance) ensures clear visibility in low light. The pure reflective mode saves power by eliminating backlighting, while the hard-coat antiglare surface reduces glare under direct sunlight. With an ultra-wide viewing angle, there’s no color deviation from any direction, supporting multi-person viewing for shared devices.

Powered by bi-stable technology, the module only consumes power during updates (max 80mAs at 25℃) and draws ≤3μA in deep sleep. A standard lithium battery can power daily-updated devices for over 12 months, reducing replacement frequency. It has a 5-year design life (25℃/60%RH, daily updates) and passed rigorous reliability tests: 240-hour high/low-temperature operation (40℃/0℃), 168-hour high-humidity operation (40℃, 90%RH), ESD testing (contact ±2KV/air ±8KV), and UV exposure resistance (765 W/㎡ for 168hrs).

With an outline of 36.7×79.0×0.9mm and weight of 5.098±0.5g, the YE029A241 fits into medium-size devices like electronic shelf labels and portable terminals. The flexible FPC with PI stiffener (0.30±0.03mm) simplifies installation in non-flat layouts. It supports 3-wire/4-wire SPI (selectable via BS pin) and I2C for temperature sensors, compatible with most MCUs and embedded systems—no complex drivers needed. Pins 6 (TSCL) and 7 (TSDA) can be grounded if external sensors aren’t used, simplifying circuit design.

The module complies with ROHS2.0+HF+REACH standards, meeting global environmental requirements. It features a hard-coat antiglare surface that resists scratches and fingerprints, protecting the display from daily wear. The 12+1 months warranty (1 month delivery time included) provides peace of mind for bulk purchases. Strict shipment inspection ensures defect-free delivery: spot defects ≤0.4mm (N≤4) in active area, no display malfunctions or errors, and scratch defects ≤5mm (W≤0.3mm, N≤2).
