The YE042A203 is an Active Matrix Electrophoretic Display (AMEPD) optimized for large-size multi-level color classification scenarios. It features a 4.2-inch active area (84.8×63.6mm) with 400×300 pixels (0.212×0.212mm square pixel pitch, 119 DPI), supporting Black/White/Red/Yellow 4-color display—ideal for precise information categorization in electronic shelf labels. The module integrates a high-performance SSD2683 driver IC, including gate buffer, source buffer, timing control, oscillator, DC-DC converter, SRAM, and LUT, ensuring stable performance. With an outline dimension of 91.00×77.00×1.15mm (without masking film) and weight of 15±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 YE042A203 excels in large-size multi-level classification scenarios with its 119 DPI display and 4-color capability. It vividly presents multi-dimensional information—red for promotions/urgent alerts, yellow for new arrivals/stock warnings, black for detailed text/barcodes, and white for background—making it perfect for large electronic shelf labels, logistics tags, and industrial terminals. Its square pixel pitch (0.212×0.212mm) ensures sharp text and clear barcodes, even multi-line content remains legible. The hard-coat antiglare surface eliminates glare under direct sunlight, maintaining readability in retail stores, warehouses, or outdoor kiosks. With a slim design (1.15mm thickness) and lightweight (15±0.5g) profile, it fits into space-constrained large devices, while ultra-low power consumption (≤3μA deep sleep) enables over 12 months of battery life for daily-updated applications.

The YE042A203 is mainly designed for large Electronic Shelf Label (ESL) systems with diverse industry applications. In retail, it serves as large electronic shelf labels for home appliances, furniture, and bulk groceries, using 4-color display to highlight promotions (red), new arrivals (yellow), 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 large cargo tags, displaying complete waybills, transportation statuses, priority levels (red for urgent, yellow for regular), withstanding -25~60℃ transportation for 10 days. In industrial control, it acts as status monitors, indicating normal (white), fault (black), urgent (red), and maintenance alerts (yellow) 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 large-size 4-color e-paper applications.

Core Advantages

◊ 4-Color Large-Size Display: Multi-Level Classification, Rich Information

The YE042A203 features a 4.2-inch large active area (84.8×63.6mm) with 400×300 high resolution (119 DPI), supporting 4-color display for refined information classification. Its optical performance is excellent: white state L*=63~65, black state L*=9~14, red state L*=25~28 (a*=38~40), yellow state L*=55~62 (b*=63~68), white reflectance 30~35%, and contrast ratio 10:1 typ. 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 large shared devices like industrial monitors or retail price tags.

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

Powered by bi-stable technology, the module only consumes power during updates (max 240mAs at 25℃) and draws ≤3μA in deep sleep. A standard lithium battery can power daily-updated large devices for over 12 months, reducing battery replacement frequency. It integrates the SSD2683 driver IC with on-chip booster/regulator, generating VCOM, Gate (VGH/VGL), and Source (VSH1/VSH2/VSL) voltages internally, simplifying external circuits. The internal temperature sensor 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), compatible with most MCUs and embedded systems—no complex drivers needed. Pins 6 and 7 on FPC are pre-ground (no need for external handling). The 24-pin 0.5mm ZIF Socket enables quick, secure installation. Waveform is stored in on-chip OTP, supporting custom programming. The flexible FPC (0.10±0.03mm) with stiffener simplifies installation in non-flat large device layouts, reducing development cycle and cost.

◊ Durable & Wide Adaptability: Harsh Environment Resistant

With an outline of 91.00×77.00×1.15mm and weight of 15±0.5g, the YE042A203 is suitable for large-size 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 -25~60℃ (max 5 years), adapting to harsh environments like cold storage, warehouses, or outdoor retail. It passed vibration testing (1.04G, 10~500Hz) 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 large electronic shelf labels and industrial devices.
