0.42 Inch PMOLED Monochrome 72×40 Resolution SSD1315 Driver IC 4-wire SPII2C Interface Low Energy Consumption Passive E-Paper
This 0.42-inch PMOLED monochrome display module is an ultra-compact and ultra-low power consumption passive organic light-emitting display screen. Equipped with 72×40 resolution, mature SSD1315 driver IC and dual 4-wire SPI & I2C interfaces, it features self-luminous imaging, high contrast and stable performance. Different from traditional LCD screens requiring backlight power supply, this PMOLED panel adopts passive light-emitting structure with extremely low energy consumption, making it perfectly suitable for micro smart devices, wearable products, low-power IoT terminals, miniature industrial meters and portable medical detection equipment.
In terms of display performance, the ultra-small 0.42-inch screen with 72×40 precise resolution delivers neat and clear pixel presentation. It stably displays characters, numbers, status icons and simple graphical interfaces, fully meeting the visualization needs of micro equipment. Featuring pure monochrome imaging and ultra-high contrast, the screen presents distinct black-and-white display effect without stray colors and blurring. With self-luminous design, it requires no backlight module, achieving fast response, zero ghosting and high recognizability in various light environments.
Powered by the industrial mature SSD1315 driver IC, the module provides strong compatibility and stable long-term operation, effectively avoiding screen flicker and display disorder. The dual 4-wire SPI and I2C interface design greatly improves equipment adaptability, supporting fast connection with mainstream single-chip microcomputers and embedded mainboards. It simplifies secondary development procedures and adapts to maker projects, experimental teaching and mass production scenarios.
Benefiting from PMOLED passive light-emitting architecture and low-power driving solution, the module achieves extremely low operating and standby power consumption, effectively extending the battery life of battery-powered micro devices. The ultra-thin and mini structure occupies minimal installation space, which is easy to be embedded in compact devices such as smart bracelets, micro sensors and portable detectors. With excellent shock resistance and aging resistance, it maintains stable display performance during long-term high-frequency operation.
Each product is individually packaged with a package size of 13×8×9cm and a gross weight of 0.2kg. The lightweight and well-protected package prevents static damage and extrusion during transportation, reducing warehousing and logistics costs. Overall, this 0.42-inch 72×40 PMOLED monochrome display module integrates ultra-small size, ultra-low power consumption, high contrast and strong compatibility, which is a cost-effective and reliable display solution for low-power micro smart equipment and embedded development projects.
