7.3inch e-Paper (E) Key Features

7.3inch e-Paper (E) features E Ink Spectra 6 (E6) full-color technology, delivering high-contrast, high-saturation color reproduction. 7.3inch e-Paper (E) offers 800×480 pixel resolution, a display area of 160×96mm, and a dot pitch of 0.2×0.2mm. The technology is based on four-color charged ink particles (red, blue, yellow, and white) that migrate under electric fields to achieve full-color display.

7.3inch e-Paper (E) display performance includes 2 grayscale levels, a full refresh time of approximately 25 seconds, and a viewing angle of >170°, closely resembling traditional paper. 7.3inch e-Paper (E) power consumption is extremely low: refresh power < 70mW, sleep current < 0.01µA, and the display retains content after power-off, making it ideal for battery-powered and long-term static display applications.

7.3inch e-Paper (E) uses a 3-wire SPI / 4-wire SPI communication interface with onboard level-shifting circuitry, compatible with 3.3V and 5V logic levels for easy integration with various controller platforms. The HAT version features a standard 40-pin GPIO header for direct connection to Raspberry Pi series boards, Jetson Nano, RDK X3, and more.

Two versions are available: bare screen (7.3inch e-Paper (E)) and module with driver board (7.3inch e-Paper HAT (E)). 7.3inch e-Paper (E) bare screen measures 170.20×111.20×0.91mm for direct embedded integration, while the HAT version includes a driver board for easy connection to development boards.

7.3inch e-Paper (E) Applications

With its full-color display, ultra-low power consumption, and wide viewing angle, 7.3inch e-Paper (E) is widely used in:

Electronic Shelf Labels (ESL): Price tags and product information displays in supermarkets, convenience stores, and warehouses

Conference Name Tags & Desktop Signs: Electronic nameplates for meetings, corporate receptions, and office desks

Industrial Instruments & Equipment Panels: Parameter displays and status indicators for industrial equipment

Smart Home & IoT: Smart home information dashboards, weather stations, calendar displays

Medical & Public Facilities: Hospital bedside cards, department signage, public information displays

Education & Prototyping: e-paper display projects based on Raspberry Pi, Arduino, and STM32

7.3inch e-Paper (E) Advantages and Highlights

The key advantage of 7.3inch e-Paper (E) lies in its E Ink Spectra 6 full-color technology, delivering superior color reproduction and ultra-low power consumption. Unlike traditional LCD screens, 7.3inch e-Paper (E) requires no backlight, remains clearly visible under direct sunlight, and produces no blue light for eye-friendly viewing. The display retains its content after power removal with near-zero power consumption, making it ideal for long-term static display applications.

7.3inch e-Paper (E) onboard level-shifting circuitry supports both 3.3V and 5V logic levels, enabling direct connection to Raspberry Pi, Jetson Nano, RDK X3, Arduino, STM32, and other mainstream controller boards with a low development barrier. Waveshare provides comprehensive documentation including driver board schematics and sample programs for Raspberry Pi, Jetson Nano, RDK X3, Arduino, and STM32 platforms.

7.3inch e-Paper (E) large screen with a 160×96mm display area and 800×480 resolution delivers rich, clear visual content for various commercial and industrial display needs. With a viewing angle of >170°, the display remains readable from all angles, closely mimicking the reading experience of traditional paper.

FAQs:

Question: What display technology does this 7.3-inch e-Paper use?
Answer: 7.3inch e-Paper (E) uses the latest E Ink Spectra 6 (E6) full-color technology, supporting microcup mixing of white, red, yellow, and blue particles to produce vivid, high-saturation images.
Question: What is the resolution and size?
Answer: 7.3inch e-Paper (E) resolution is 800 × 480 pixels, with an active area of 160 × 96mm and a dot pitch of 0.2 × 0.2mm.
Question: How is the power consumption?
Answer: 7.3inch e-Paper (E) has ultra-low power consumption, only drawing power during refresh (< 70mW), and its standby current is almost zero (< 0.01uA). It retains the last image even when unplugged.
Question: How long does a full refresh take?
Answer: 7.3inch e-Paper (E) full refresh time is approximately 25 seconds.
Question: What interfaces does it support?
Answer: 7.3inch e-Paper (E) supports 3-wire or 4-wire SPI interfaces, compatible with Raspberry Pi, Jetson Nano, Arduino, or STM32 controllers.
Question: What versions are available?
Answer: 7.3inch e-Paper (E) has a "Raw display" version (3.3V, without driver board) and a "HAT version" (3.3V/5V, with driver board attached).
Question: How does it differ from the 7-color (ACeP) version?
Answer: The 7-color version uses ACeP technology, while 7.3inch e-Paper (E) uses red, yellow, and blue particles to achieve better contrast and saturation, resulting in brighter and clearer colors.
