The YE037A30 is an Active Matrix Electrophoretic Display (AMEPD) optimized for medium-to-large size high-info scenarios. It features a 3.7-inch active area (47.04×81.54mm) with 240×416 pixels (0.196×0.196mm pitch, 130 DPI), supporting Black/White 2-color display—ideal for clear presentation of detailed information 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 (53×92.99×0.9mm without masking film) and lightweight design (8.5±0.5g), it fits seamlessly into devices like large electronic shelf labels, logistics tags, and industrial control 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 YE037A30 excels in medium-to-large size high-info scenarios with its 130 DPI display and 2-color high contrast. It clearly presents detailed black-and-white information—ideal for displaying product descriptions, multi-line prices, and barcodes in large electronic shelf labels, logistics tags, and industrial terminals. Its square pixel pitch (0.196×0.196mm) ensures sharp text and graphics, 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) design, it fits into space-constrained devices, while ultra-low power consumption (≤3μA deep sleep) enables over 12 months of battery life for daily-updated applications.

The YE037A30 is mainly designed for Electronic Shelf Label (ESL) systems with diverse industry applications. In retail, it serves as large electronic shelf labels for bulky products (e.g., home appliances, furniture), displaying detailed product info, prices, and stock status—enhancing customer information access. Its low power consumption reduces retail maintenance costs. In logistics, it functions as large cargo tags, displaying complete waybills and transportation statuses, withstanding -25~60℃ transportation for 10 days. In industrial control, it acts as status monitors, indicating normal (white background with black text) and fault (black background with white text) states for equipment. With ROHS2.0 compliance and rigorous reliability testing, it meets global environmental and reliability demands.

Core Advantages

◊ High-Resolution Large Display: More Info, Sharper Details

The YE037A30 features 240×416 high resolution (130 DPI) with 0.196×0.196mm square pixels, delivering sharp text, multi-line content, and barcodes—ideal for displaying detailed information. Its 2-color performance is outstanding: white reflectance 30~35%, contrast ratio typ. 10:1, 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 brightness deviation from any direction, supporting multi-person viewing for shared devices.

◊ Ultra-Low Power & Broad Temperature Range: Versatile Adaptation

Powered by bi-stable technology, the module only consumes power during updates (max 50mAs at 25℃) and draws ≤3μA in deep sleep. A standard lithium battery can power daily-updated devices for over 12 months. It supports a broad operating temperature range (0~50℃) and transportation temperature (-25~60℃ for 10 days), adapting to harsh environments like cold storage or high-temperature workshops. The on-chip booster generates driving voltages internally, simplifying circuits. The internal/external temperature sensor (I2C) enables real-time waveform adjustment, ensuring stability in extreme temperatures.

◊ Durable & Easy Integration: Low Development Cost

With an outline of 53×92.99×0.9mm, the YE037A30 fits into medium-to-large size devices. It passed rigorous reliability tests: 240-hour high/low-temperature operation (40℃/0℃), 100 temperature cycles (-25℃~70℃), 168-hour high-humidity operation (40℃, 90%RH), vibration testing (1.04G, 20~200Hz), and drop impact (100cm height). The hard-coat screen resists scratches and fingerprints, while ROHS2.0 compliance meets global standards. Its long service life ensures long-term use, while the flexible FPC (0.10±0.03mm) with stiffener (0.30±0.03mm) simplifies installation in non-flat layouts.

◊ Flexible Interface: Wide Compatibility

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, adapting to diverse application needs like large ESLs and industrial monitors.
