3.5 Inch E Paper Display 184*384 Resolution 24 Pin Low Power Consumption E Ink Display

The YE035A32 E-PAPER display module excels in compact scenarios with its high-resolution monochrome display and wide temperature adaptability. As shown in the images, it can clearly present text, barcodes, and simple graphics—its 122 DPI resolution and rectangular pixels (0.2075×0.2075mm) ensure sharp details, even for small 8pt fonts, making it ideal for displaying product prices, inventory codes, and basic data. The hard-coat antiglare surface eliminates glare under direct sunlight, maintaining readability in retail stores, logistics warehouses, or outdoor kiosks. Whether used for mini electronic shelf labels, smart cargo tags, or portable data terminals, its ultra-thin (0.9mm) design fits seamlessly into space-constrained devices, while low power consumption (≤3μA deep sleep) ensures long battery life without frequent replacements.

The YE035A32 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, snacks), displaying real-time prices, stock levels, and promotional information—its low power consumption eliminates frequent battery replacements, reducing retail maintenance costs. The high contrast (10 typ.) ensures clear readability even in dimly lit stores. In logistics and warehousing, it functions as compact cargo tags, displaying waybills, destination details, and inventory statuses, withstanding transportation temperatures of -25~60℃ for up to 10 days. In smart wearables and portable devices, its lightweight and thin design fits into fitness trackers, smart nameplates, and handheld scanners, serving as a low-power information display. Additionally, in industrial control, it works as small equipment status monitors, showing parameters like temperature, pressure, and running status—supporting landscape/portrait modes to adapt to different device layouts. With ROHS2.0+HF+REACH compliance and rigorous reliability testing (including high-temperature, low-temperature, and vibration tests), it meets environmental and long-term use requirements in diverse scenarios.

The YE035A32 adopts pure reflective display technology without a backlight, delivering a paper-like visual experience with a white state reflectance of 35% (typ.) and contrast ratio of 10 (typ.)—ensuring clear and sharp text and images even in bright environments. Its 184×384 resolution (122 DPI) and rectangular pixels (0.2075×0.2075mm) avoid image distortion, making it ideal for displaying barcodes, small fonts, and simple graphics. The hard-coat antiglare surface reduces glare under direct sunlight, maintaining readability in outdoor or bright indoor scenarios. With an ultra-wide viewing angle (no color/brightness deviation from 12 o'clock, 3 o'clock, 6 o'clock, 9 o'clock directions), it supports multi-person viewing, suitable for retail shelves or public information displays. Additionally, it supports both landscape and portrait modes, adapting to different installation orientations.

Based on bi-stable display technology, the module only consumes power during screen refresh—panel power consumption is 26 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 (programmable via commands), Gate (VGH: 10~20V selectable, VGL: -5~-17V selectable), and Source (VSH1/VSH2: 2.4~17V selectable, VSL: -5~-17V selectable) driving voltages internally, reducing external circuit complexity and optimizing power efficiency. It also supports soft start control (via 0x0C command) to adjust booster phase current and duration, preventing voltage surges and further reducing energy consumption. Low-voltage detection (LVD) monitors battery status (VCI: 2.5~3.7V), ensuring reliable operation even in power-fluctuating environments.

The YE035A32 features excellent environmental adaptability: it operates stably at -15~65℃ (45~70%RH, normal use guaranteed 0~50℃) and can withstand transportation temperatures of -25~60℃ for up to 10 days. 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 (+/-250V, 0Ω, 200pF)—ensuring no functional failures or appearance defects. The FPC+PI stiffener design (total thickness 0.30±0.03mm) enhances mechanical stability during installation, while the hard-coat screen is scratch-resistant and fingerprint-resistant. With ROHS2.0+HF+REACH compliance, it meets global environmental standards, making it suitable for international markets. The module also supports special waveform customization for 0~50℃ operation, ensuring stable display quality in extreme temperature environments.

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 SSD1685 driver IC offers rich commands for display control: resolution adjustment (via 0x21 command, 168×384/184×384/200×384/216×384 selectable), RAM window setting (via 0x44/0x45 commands), and border waveform control (via 0x3C command). It includes 10-byte OTP space for storing module identification (e.g., production batch, serial number), enabling easy device management and traceability. The 24-pin 0.5mm ZIF Socket ensures secure and easy installation, while the easy-to-tear sticker design simplifies assembly in mass production. Additionally, it supports partial refresh (via RAM address counter settings) and waveform LUT loading from OTP or MCU, adapting to different refresh speed and display quality requirements.
