3.7 Inch E-paper Display 240*416 Resolution 24pin Low Power Consumption E-Ink

The YE037A30 E-PAPER display module stands out with its compact size and high-performance monochrome display. As shown in the images, it can clearly present text, barcodes, and simple graphics—its 130 DPI resolution and rectangular pixels (0.196×0.196mm) 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 lightweight (8.5g) and ultra-thin (0.90mm) design fits seamlessly into space-constrained devices, while low power consumption (≤3μA deep sleep) ensures long battery life without frequent replacements.

The YE037A30 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 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 YE037A30 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 240×416 resolution (130 DPI) and rectangular pixels (0.196×0.196mm) 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 50 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 0x82 command, -0.1~-12.7V), Gate (VGH/VGL, 10~20V/-10~-20V selectable), and Source (VSH/VSL/VDHR, 2.4~15V/-2.4~-15V selectable) driving voltages internally, reducing external circuit complexity and optimizing power efficiency. It also supports power-saving mode (via 0xE3 command) to adjust VCOM/Source power-saving width, further reducing energy consumption during refresh. Low-voltage detection (LVD) monitors battery status (VDD: 2.5~3.6V), ensuring reliable operation even in power-fluctuating environments.

With an ultra-thin outline dimension of 53×92.99×0.90mm and lightweight design (8.5±0.5g), the YE037A30 fits into compact devices like smart wearables and mini electronic shelf labels. It features excellent environmental adaptability: operating at 0~50℃ (35~70%RH) and withstanding 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, 100 temperature cycles (-25℃~70℃), 168-hour high-temperature high-humidity (40℃, 90%RH) operation, and ESD testing (+/-250V, 0Ω, 200pF)—ensuring no functional failures or appearance defects. The hard-coat screen is scratch-resistant and fingerprint-resistant, while ROHS2.0 compliance meets global environmental standards, making it suitable for international markets. The FPC+PI stiffener design (total thickness 0.30±0.03mm) enhances mechanical stability during installation.

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 UC8253C driver IC offers rich commands for display control: resolution setting (via 0x61 command, 240×416 default, adjustable), gate/source start position setting (via 0x65 command), VCOM DC adjustment (via 0x82 command, -0.1~-12.7V), and power-saving mode (via 0xE3 command). On-chip OTP stores waveform data, reducing external memory requirements, while PLL control (via 0x30 command) supports frame rates from 5Hz to 200Hz, adapting to different refresh speed needs. 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 custom waveform programming and partial refresh (via RAM window settings) to meet specific application scenarios.
