The YE037A24 is an Active Matrix Electrophoretic Display (AMEPD) optimized for medium-to-large color-coded scenarios. It features a 3.7-inch active area (47.04×81.54mm) with 240×416 pixels (0.202×0.203mm pitch, 129 DPI), supporting Black/White/Red 3-color display—ideal for clear information classification in electronic shelf labels. The module integrates a UC8253C driver IC, including gate buffer, source buffer, timing control, oscillator, DC-DC converter, SRAM, and LUT, ensuring stable performance. With an ultra-thin outline (53×92.99×0.95mm without masking film) and lightweight design (8.5±0.2g), it fits seamlessly into devices like electronic shelf labels, logistics tags, and industrial terminals. The hard-coat antiglare surface and pure reflective mode eliminate glare under strong light, while bi-stable technology ensures ultra-low power consumption—only drawing current during screen updates.

Product Picture

The YE037A24 excels in medium-to-large color-coded scenarios with its 129 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, logistics tags, and industrial terminals. Its pixel pitch (0.202×0.203mm) 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 (0.95mm) and lightweight (8.5±0.2g) design, it fits into space-constrained devices like large smart labels, while ultra-low power consumption (≤3μA deep sleep) enables over 12 months of battery life for daily-updated applications.

The YE037A24 is mainly designed for Electronic Shelf Label (ESL) systems with diverse industry applications. In retail, it serves as large electronic shelf labels for home appliances, furniture, and groceries, using 3-color display to highlight promotions (red), product names/prices (black), and stock status (white background)—enhancing customer information access. Its low power consumption reduces retail maintenance costs. In logistics, it functions as cargo tags, displaying waybills and transportation statuses with red for urgent shipments, withstanding -25~60℃ transportation for 10 days. In industrial control, it acts as status monitors, indicating normal (white), fault (black), and urgent (red) states for equipment. In smart wearables, its compact size fits into large fitness trackers or industrial badges, showing work status or alert notifications. With ROHS2.0+REACH compliance and rigorous reliability testing, it meets global environmental and reliability demands.

Core Advantages

◊ 3-Color High-Contrast Display: Clear Classification, Precise Presentation

The YE037A24 features 240×416 resolution (129 DPI) with 0.202×0.203mm pixels, delivering sharp text, barcodes, and 3-color graphics—ideal for information classification. Its color performance is precise: red state L*=25~28 (a*=36~40), with high white 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. With an ultra-wide viewing angle, there’s no color deviation from any direction, supporting multi-person viewing for shared devices like electronic shelf labels.

◊ Ultra-Low Power: Long Battery Life, Energy Efficiency

Powered by bi-stable technology, the module only consumes power during updates (max 180mAs 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 (VDH/VDL/VDHR) voltages internally, simplifying external circuits and optimizing efficiency. Low-voltage detection (VDD: 2.5~3.6V) 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 0~40℃ environments.

◊ Compact & Durable: Easy Integration, Wide Adaptability

With an outline of 53×92.99×0.95mm and weight of 8.5±0.2g, the YE037A24 fits into medium-to-large devices like electronic shelf labels and industrial terminals. It passed rigorous reliability tests: 240-hour high/low-temperature storage (50℃/-25℃), 168-hour high-humidity operation (40℃, 90%RH), 50 temperature cycles (-25℃~60℃), and ESD testing (±250V). The hard-coat screen resists scratches and fingerprints, while ROHS2.0+REACH compliance meets global standards. Its 5-year design life (25℃/60%RH, daily updates) ensures long-term use. The flexible FPC (0.10±0.03mm) with stiffener simplifies installation in non-flat layouts.

◊ Flexible Interface & Easy Integration: Low Development Cost

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. Pins 6 (TSCL) and 7 (TSDA) must be grounded if external temperature sensors aren’t used (not NC). The 24-pin 0.5mm ZIF Socket enables quick, secure installation. Customizations include FPC layout/connector type, cover glass processing (logo/pattern printing), and OTP programming (10-byte module identification, waveform parameters), adapting to diverse application needs like electronic shelf labels and industrial monitors.
