Product Picture
The YE035A32 excels in medium-to-large size high-info scenarios with its 122 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 (0.2075×0.2075mm) 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 YE035A32 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+HF+REACH compliance and rigorous reliability testing, it meets global environmental and reliability demands.
Core Advantages
The YE035A32 features 184×384 high resolution (122 DPI) with 0.2075×0.2075mm square pixels, delivering sharp text, multi-line content, and barcodes—ideal for displaying detailed information. Its 2-color performance is outstanding: white state L*=67, black state L*=18, with high reflectance and contrast ratio 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.
Powered by bi-stable technology, the module only consumes power during updates (max 26mAs 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 (-15~65℃), adapting to harsh environments like cold storage or high-temperature workshops (normal use 0~50℃). 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.
With an outline of 45.03×91.75×0.9mm, the YE035A32 fits into medium-to-large size devices. It passed rigorous reliability tests: 240-hour high/low-temperature operation (40℃/0℃), 50 temperature cycles (-25℃~60℃), 168-hour high-humidity operation (40℃, 90%RH), and ESD testing (machine model ±250V). 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 (0.10±0.03mm) with PI stiffener (0.30±0.03mm) simplifies installation in non-flat layouts.
The module supports 3-wire/4-wire SPI (selectable via BS1 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), adapting to diverse application needs like large ESLs and industrial monitors.
