The YE0437A07 excels in long-strip color-coded scenarios with its 117 DPI display and 3-color capability. It vividly presents dual-level information—red for promotions/urgent alerts, black for detailed text/barcodes, and white for background—making it perfect for long electronic shelf labels, logistics tags, and industrial terminals. Its 176×480 long-strip resolution is tailored for narrow and tall information display, such as product specifications or price tiers. The hard-coat antiglare surface eliminates glare under direct sunlight, maintaining readability in retail stores, warehouses, or outdoor kiosks. With an ultra-thin (0.90mm) design, it fits into space-constrained long devices, while ultra-low power consumption (≤3μA deep sleep) enables over 12 months of battery life for daily-updated applications.
The YE0437A07 is mainly designed for long Electronic Shelf Label (ESL) systems with diverse industry applications. In retail, it serves as long electronic shelf labels for beverages, cosmetics, and narrow-format products, using 3-color display to highlight promotions (red), detailed product descriptions/prices (black), and stock status (white background)—enhancing customer information access and reducing manual label updates. Its low power consumption reduces retail maintenance costs. In logistics, it functions as long cargo tags, displaying complete waybills, transportation statuses, and urgent markers (red for priority 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. With ROHS2.0+HF+REACH compliance and rigorous reliability testing (high/low temperature, vibration, drop impact), it meets global environmental and reliability demands for long-strip 3-color e-paper applications.
Core Advantages

◊ Long-Strip 3-Color Display: Clear Classification, Tailored for Narrow Scenarios

The YE0437A07 features a 4.37-inch long-strip active area (38.19×104.16mm) with 176×480 resolution (117 DPI), supporting 3-color display for dual-level information classification. Its optical performance is excellent: white state L*=63~65, black state L*=13~14, red state L*=25~28 (a*=36~40), white reflectance 30~35%, and contrast ratio 10~15:1. 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 or brightness deviation from any direction, supporting multi-person viewing for long shared devices.

◊ Ultra-Low Power & Stable Performance: Long-Term Reliability

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 long devices for over 12 months, reducing battery replacement frequency. It integrates the UC8253 driver IC with on-chip booster/regulator, generating VCOM, Gate (VGH/VGL), and Source (VDHR/VDH/VDL) voltages internally, simplifying external circuits. The internal/external temperature sensor (I2C) enables real-time waveform adjustment, ensuring stable operation in 0~40℃. It passed rigorous reliability tests, including 240-hour high/low-temperature storage, 168-hour high-humidity operation, and 50 temperature cycles (-25℃~60℃), ensuring long-term use.

◊ 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. It includes 10-byte OTP space for module identification, supporting custom programming. The flexible FPC (0.10±0.03mm) with PI stiffener (0.30±0.03mm) simplifies installation in non-flat long device layouts, reducing development cycle and cost.

◊ Durable & Wide Adaptability: Harsh Environment Resistant

With an outline of 46.6×115.86×0.90mm, the YE0437A07 is tailored for long-strip device integration. The hard-coat antiglare surface resists scratches and fingerprints, while ROHS2.0+HF+REACH compliance meets global environmental standards. It supports transportation temperature -25~60℃ (10 days) and storage temperature 0~40℃ (max 5 years), adapting to harsh environments like cold storage, warehouses, or outdoor retail. It passed vibration testing (1.04G, 20~200Hz) and drop impact (100cm height on concrete), ensuring durability during transportation and use. The 5-year design life (25℃/60%RH, daily updates) guarantees long-term reliable operation for long electronic shelf labels and industrial devices.
