7.5 Inch E Paper Display 800*480 Resolution 24pin Low Power E Ink Display Screen

The YE075A42 E-PAPER display module excels in clear information presentation and low-power operation. As shown in the images, it can vividly display product details, pricing, and promotional content—its high contrast (15 typ.) and white reflectance (35% typ.) ensure content remains sharp even under direct sunlight, while the hard-coat antiglare surface eliminates glare. Whether used for electronic shelf labels in retail stores, smart cargo labels in logistics, or digital notice boards in offices, its square pixel design (0.204×0.204mm) delivers balanced image quality, making key information easily recognizable for users.

The YE075A42 E-PAPER display module has a wide range of applications across multiple industries. In retail, it serves as electronic shelf labels, supporting real-time updates of product prices, stock levels, and discount information—its low power consumption (≤3μA deep sleep) eliminates frequent battery replacements, reducing maintenance costs. In logistics and warehousing, it functions as smart cargo labels, displaying waybills, destination details, and inventory statuses, withstanding transportation temperatures of -25~60℃ for up to 10 days. In smart offices and homes, it acts as digital notice boards or control panels, showing schedules, weather forecasts, or device statuses—its paper-like visual experience reduces eye strain during long-term viewing. Additionally, in educational institutions, it works as classroom information displays or electronic nameplates, supporting landscape and portrait modes to adapt to different installation environments. With its compact size (170.2×111.2mm), lightweight design (44g), and ROHS compliance, it meets the diverse needs of modern smart scenarios.

The YE075A42 adopts pure reflective display technology without a backlight, delivering a paper-like visual experience with a white state L* value of 63~65, dark state L* value of 13~14, and contrast ratio of 15 (typ.)—ensuring clear and sharp text and images. Its square pixel design (0.204×0.204mm) avoids image distortion, making it ideal for displaying barcodes, tables, and graphics. 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 or brightness deviation when viewed from any direction, supporting multi-person viewing scenarios such as retail shelves or office dashboards. 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 250 mAs (typ. at 25℃/40℃) and 450 mAs (max. at 0℃), 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 (VDH/VDL/VDHR) driving voltages internally, reducing external circuit complexity and optimizing power efficiency. It also supports low-power detection (LPD) to monitor battery status, ensuring reliable operation even when voltage drops to 2.2V (selectable via LVD_SEL).

The YE075A42 features excellent environmental adaptability: it operates stably at 0~40℃ (45~70%RH) 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℃), and 168-hour high-temperature high-humidity (40℃, 90%RH) operation—ensuring no functional failures or appearance defects. The hard-coat screen is scratch-resistant and fingerprint-resistant, preventing damage from daily friction. With a designed service life of 5 years (under normal use: 0~35℃, 45~70%RH, updated once daily) and ROHS compliance, 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 external temperature sensors, compatible with most microcontrollers, PLCs, and embedded systems—no complex driver development required. It includes an internal temperature sensor (with offset calibration) for real-time temperature monitoring and waveform adjustment, ensuring stable performance under temperature fluctuations. The UC8179 driver IC (COG package, 280μm thickness) enables compact module design, while rich commands (e.g., partial refresh, auto VCOM measurement, power saving) support customization for different scenarios. The 24-pin 0.5mm pitch connector ensures secure and easy installation, reducing integration difficulty for developers. Additionally, it supports cascade settings for multi-module synchronization, expanding application flexibility.
