SPI Interface EPD 1.54 inch Product Introduction
SFEPM154ZYBW-7174AN is an active matrix electrophoretic display (AM
EPD) with SPI interface. This 1.54-inch e-ink display module has an
effective area of 152 × 152 pixels and can display images with
1-bit black and white capability. This module is a TFT array driven
electrophoretic display, and the integrated circuit includes gate
driver, source driver, MCU interface, timing controller,
oscillator, etc DC-DC,SRAM,LUT,VCOM. This module can be used for
portable electronic devices, such as electronic shelf labeling
(ESL) systems.
Features
- E-Ink display module, 1.54 inches, 152x152 resolution, communicates
through SPI interface, supports black and white display.
- No backlight, even if the power is turned off, the last content can
be displayed for a long time.
- SPI interface, used to connect Raspberry Pi/Galileo and other
controller boards.
- Ultra low power consumption, basically only requires refreshing the
power supply; Onboard voltage converter, compatible with 3.3V/5V
MCU.
- Application: Electronic Shelf Label System, e-paper readers,
monitors, wearable products.
