The YE027A71 excels in medium-size high-definition scenarios with its 117 DPI display and 2-color high contrast. It clearly presents black-and-white information, making it perfect for electronic shelf labels, smart wearables, and portable terminals. Its pixel pitch (0.217×0.217mm) 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 (0.90mm) and lightweight (5.0g) 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 YE027A71 has diverse industry applications. In retail, it serves as standard electronic shelf labels for various products (e.g., groceries, electronics), using black-white high contrast to display product names, prices, and stock status—enhancing customer information access. Its low power consumption reduces retail maintenance costs. In logistics, it functions as cargo tags, displaying waybills and transportation statuses, 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 identification information. In industrial control, it acts as status monitors, indicating normal (white background with black text) and fault (black background with white text) states. With ROHS2.0+HF+REACH compliance and rigorous reliability testing, it meets global environmental and reliability demands.

The YE027A71 features 176×264 resolution (117 DPI) with 0.217mm pixels, delivering sharp text, barcodes, and graphics—ideal for displaying clear information in medium-size scenarios. Its 2-color performance is outstanding: white state L*≥64, black state L*≤14, with high reflectance and contrast ratio (white reflectance divided by dark reflectance) ensuring 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, maintaining readability in outdoor/bright indoor scenarios. With an ultra-wide viewing angle, there’s no brightness deviation from any direction, supporting multi-person viewing for shared devices.

Powered by bi-stable technology, the module only consumes power during updates (max 70mAs at 25℃) and draws ≤3μA in deep sleep. A standard lithium battery can power daily-updated devices for over 12 months, reducing replacement frequency. The on-chip booster generates VCOM, Gate (VGH/VGL), and Source (VSH1/VSH2/VSL) voltages internally, simplifying external circuits and optimizing efficiency. Low-voltage detection (VCC: 2.4~3.6V) monitors battery status, while high-voltage ready detection prevents abnormal operation. The internal/external temperature sensor (I2C) enables real-time waveform adjustment, ensuring stability in 0~50℃ environments.

With an outline of 45.8×70.42×0.90mm and weight of 5.0±0.2g, the YE027A71 fits into medium-size devices like electronic shelf labels and portable terminals. It passed rigorous reliability tests: 240-hour high/low-temperature operation (40℃/0℃), 50 temperature cycles (-25℃~70℃), 168-hour high-humidity operation (40℃, 90%RH), and ESD testing (contact ±2KV/air ±8KV). The hard-coat screen resists scratches and fingerprints, while ROHS2.0+HF+REACH compliance meets global standards. Its 5-year design life (25℃/60%RH, daily updates) ensures long-term use. The flexible FPC with PI stiffener simplifies installation in non-flat layouts.

The module 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. The 26-pin 0.5mm ZIF Socket and easy-to-tear sticker enable quick, secure installation. Customizations include FPC length/bending area (for non-flat devices), cover glass processing (anti-glare/anti-fingerprint), and OTP programming (10-byte user ID, waveform parameters), adapting to diverse application needs like electronic shelf labels and industrial monitors.
