4.37 Inch E-paper Display 176*480 Resolution 24pin Low Power Consumption E-Ink

The YE0437A08 E-PAPER display module excels in compact scenarios with its 4-color display and small form factor. As shown in the images, it can vividly present color-coded information—such as red for promotions, yellow for warnings, and black/white for basic content—making it ideal for mini electronic shelf labels, smart wearables, and portable terminals. Its 117 DPI resolution and rectangular pixels (0.217×0.217mm) ensure sharp text and graphics, even in limited screen space, while the hard-coat antiglare surface eliminates glare under direct light, maintaining readability in retail stores, logistics warehouses, or outdoor kiosks. Whether used for displaying product prices, cargo labels, or health data, its ultra-thin (0.90mm) and lightweight design fits seamlessly into space-constrained devices, while low power consumption ensures long battery life.

The YE0437A08 E-PAPER display module has a wide range of applications across multiple industries. In retail, it serves as mini electronic shelf labels for small-sized products (e.g., cosmetics, stationery), using 4-color display to highlight promotional items (red), new arrivals (yellow), and regular goods (black/white)—enabling customers to quickly identify key information. Its low power consumption (≤3μA deep sleep) eliminates frequent battery replacements, reducing retail maintenance costs. In logistics and warehousing, it functions as compact cargo tags, displaying waybills, destination details, and inventory statuses with color-coded alerts (e.g., yellow for urgent shipments), while withstanding transportation temperatures of -25~60℃ for up to 10 days. In smart wearables and portable devices, its ultra-thin (0.90mm) and lightweight design fits into fitness trackers, smart nameplates, and handheld terminals, serving as a low-power information display. Additionally, in industrial control, it works as small equipment status monitors, using color coding to indicate normal (white), warning (yellow), and fault (red) states—supporting landscape/portrait modes to adapt to different device layouts. With ROHS2.0+HF+REACH compliance and rigorous reliability testing, it meets environmental and long-term use requirements in diverse scenarios.

The YE0437A08 supports Black/White/Red/Yellow 4-color full-display, with precise color performance: red state L*=25~28 (a*=38~40), yellow state L*=55~62 (b*=63~68), white state L*=63~65, and black state L*=9~14. This enables color-coded information classification, ideal for scenarios like retail promotions and logistics alerts. Its compact outline dimension (46.6×115.86×0.90mm) and lightweight design fit into small devices, while the 176×480 resolution (117 DPI) ensures sharp text and graphics—even small fonts (8pt) remain legible. The pure reflective mode and high white reflectance (35% typ.) deliver a paper-like visual experience, while the hard-coat antiglare surface reduces glare under direct sunlight, maintaining readability in outdoor or bright indoor environments. With an ultra-wide viewing angle, there is no color/brightness deviation from any direction, supporting multi-person viewing.

Based on bi-stable display technology, the module only consumes power during screen refresh—panel power consumption is 150 mAs (typ. at 25℃), while deep sleep mode current is ≤3μA. When paired with a standard lithium battery, electronic shelf labels refreshed once daily can operate for over 12 months without replacement. The integrated on-chip booster generates VCOM, Gate (VGH/VGL), and Source (VSH1/VSH2/VSL) driving voltages internally, reducing external circuit complexity and optimizing power efficiency. It also supports low-voltage detection (LVD) to monitor battery status (VCC: 2.4~3.6V) and high-voltage ready detection to prevent abnormal operation due to insufficient driving voltages, ensuring stable performance in power-fluctuating environments.

The YE0437A08 features excellent environmental adaptability: operating at 0~40℃ (45~70%RH) and withstanding transportation/storage temperatures of -25~60℃ (max 10 days above 40℃). It has passed rigorous reliability tests, including 240-hour high-temperature (40℃) and low-temperature (0℃) operation, 50 temperature cycles (-25℃~60℃), 168-hour high-temperature high-humidity (40℃, 90%RH) operation, and ESD testing (contact ±2KV/air ±8KV)—ensuring no functional failures or appearance defects. The hard-coat screen is scratch-resistant and fingerprint-resistant, while ROHS2.0+HF+REACH compliance meets global environmental standards, making it suitable for international markets. With a designed service life of 5 years (under normal use: 25℃/60%RH, updated once daily), it meets long-term use requirements in industrial, retail, and logistics fields.

The module supports 3-wire/4-wire SPI interfaces (selectable via the BS pin) and I2C for internal/external temperature sensors, compatible with most microcontrollers, PLCs, and embedded systems—no complex driver development required. The IST7163CA1-C driver IC ensures stable signal processing and display control, while on-chip OTP stores waveform data, reducing external memory requirements. It includes an internal temperature sensor (with I2C master interface for external sensors) for real-time temperature monitoring and waveform adjustment, ensuring stable performance under temperature fluctuations. The 24-pin connector and easy-to-tear sticker design ensure secure and convenient installation, while support for landscape/portrait modes adapts to different device layouts. Additionally, it offers customizations like FPC length, cover glass processing, and waveform parameters to meet specific application needs.
