Product Picture

The YE0154A206 excels in ultra-compact high-definition scenarios with its 188 DPI square display and 2-color high contrast. It clearly presents black-and-white information, making it perfect for micro electronic shelf labels, smart wearables, and portable terminals. Its square pixels (0.135×0.135mm) ensure sharp text and barcodes, even 6pt 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 (2.1g) design, it fits into space-constrained devices like smart badges, while ultra-low power consumption (≤3μA deep sleep) enables over 12 months of battery life for daily-updated applications.
The YE0154A206 has diverse industry applications. In retail, it serves as micro electronic shelf labels for small products (e.g., cosmetics, jewelry), 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 mini 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 tiny status monitors, indicating normal (white background with black text) and fault (black background with white text) states. With ROHS2.0+REACH compliance and rigorous reliability testing, it meets global environmental and reliability demands.
Core Advantages

The YE0154A206 features a 200×200 square resolution (188 DPI) with 0.135mm square pixels, delivering sharp text, barcodes, and graphics—ideal for displaying dense information in compact spaces. Its 2-color performance is outstanding: white state L*≥67, black state L*≤18, with high white reflectance (30~35%) and 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, 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 10mAs 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 (VCI: 2.5~3.7V) 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 37.32×31.80×0.95mm and weight of 2.1±0.2g, the YE0154A206 fits into ultra-compact devices like smart wearables and micro labels. It passed rigorous reliability tests: 240-hour high/low-temperature operation (40℃/0℃), 100 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+REACH compliance meets global standards. Its 5-year design life (0~50℃, daily updates) ensures long-term use. The flexible FPC (0.10±0.03mm) with 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) can be freely configured if external sensors aren’t used, simplifying circuit design. The 24-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.
