2.9 Inch E-paper Display 128×296 Resolution 24pin Low Power Consumption 4-Color E-Ink Screen

The YE029A260 E-PAPER display module stands out with its 4-color display and balanced size, making it ideal for scenarios requiring rich information classification. As shown in the images, it can vividly present color-coded content—red for promotions, yellow for warnings, black for product names, and white for background—perfect for electronic shelf labels, smart cargo tags, and portable terminals. Its 111 DPI resolution and rectangular pixels (0.227×0.226mm) ensure sharp text and graphics, even small fonts (8pt) remain legible. The hard-coat antiglare surface eliminates glare under direct sunlight, maintaining readability in retail stores, logistics warehouses, or outdoor kiosks. With an ultra-thin (0.9mm) and lightweight (5g) design, it fits seamlessly into space-constrained devices, while low power consumption (≤3μA deep sleep) ensures long battery life without frequent replacements.

The YE029A260 E-PAPER display module has a wide range of applications across multiple industries. In retail, it serves as electronic shelf labels for medium-sized products (e.g., snacks, daily necessities), using 4-color display to highlight promotional items (red), limited-stock alerts (yellow), new arrivals (white background with black text), and regular goods (black text on 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 cargo tags, displaying waybills, destination details, and inventory statuses with color-coded alerts (e.g., red for urgent shipments, yellow for fragile goods), while withstanding transportation temperatures of -25~60℃ for up to 10 days. In smart wearables and portable devices, its balanced size and weight fit into fitness trackers, smart badges, and handheld terminals, serving as a low-power information display—showing steps, heart rate, or device statuses. Additionally, in industrial control, it works as equipment status monitors, using color coding to indicate normal (white), warning (yellow), fault (black), and urgent (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 YE029A260 supports Black/White/Red/Yellow 4-color full-display, with precise color performance: red state L*=24 (a*=37~40 typ.), yellow state L*=53 (b*=57~68 typ.), white state L*=63~65, and black state L*=9~14. This enables multi-level information classification, ideal for retail promotions, logistics alerts, and equipment status monitoring. Its balanced outline dimension (36.7×79×0.9mm) and lightweight design (5.0±0.2g) fit into various devices—from electronic shelf labels to portable terminals. The 128×296 resolution (111 DPI) and rectangular pixels (0.227×0.226mm) ensure sharp text and graphics—even small fonts (8pt) remain legible. The pure reflective mode and high white reflectance 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 70 mAs (max. 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 (VSH/VSHR/VSL) driving voltages internally, reducing external circuit complexity and optimizing power efficiency. It also supports low-voltage detection (LVD) to monitor battery status (VDD: 2.5~3.6V, selectable LVD level: 2.2~2.5V) and high-voltage ready detection to prevent abnormal operation due to insufficient driving voltages, ensuring stable performance in power-fluctuating environments. The internal/external temperature sensor (I2C interface) enables real-time temperature monitoring and waveform adjustment, maintaining display stability under temperature fluctuations (0~40℃).

The YE029A260 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, 100 temperature cycles (-25℃~60℃), 168-hour high-temperature high-humidity (40℃, 90%RH) operation, and ESD testing (contact ±200V/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℃/50%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 BS1 pin) and I2C for internal/external temperature sensors, compatible with most microcontrollers, PLCs, and embedded systems—no complex driver development required. The JD79661 driver IC offers rich commands for display control: resolution adjustment (128×296/128×250/112×204 selectable via R00H register), partial window refresh (via R83H register), and auto VCOM measurement (via R80H register). It also supports auto sequence control (R17H command: PON→DRF→POF/DSLP), minimizing idle time and reducing host control complexity. The 24-pin 0.5mm ZIF Socket 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—such as adjusting VCOM voltage (OTP-programmed) for optimized contrast in different scenarios.
