LORDWORLD 3inch E-Paper (G) Raw Display Panel 400 × 168

SKU CH-3VMW-N8SV1

A 3-inch e-paper panel with 400 × 168 resolution retains images without power and includes driver resources for Raspberry Pi, Arduino and STM32

  • Ultra-low power draw, only needed during screen refresh
  • Retains last image indefinitely without any backlight power
  • 400 × 168 resolution on a 3-inch e-paper panel
  • SPI interface for direct microcontroller integration
  • Includes driver schematics and code examples for Raspberry Pi, Arduino, STM32

3-inch E-Paper Raw Display Panel

This raw e-paper panel measures three inches diagonally and presents a 400 by 168 pixel resolution. It connects through a SPI interface and requires power only during refresh cycles. The display retains its last image indefinitely without a backlight or continuous supply. Development resources including driver-board schematics and example code for Raspberry Pi, Arduino and STM32 platforms are provided.

Makers building low-power signage or sensor readouts

Developers creating battery-powered badges, shelf labels or environmental monitors will benefit from the ultra-low consumption and persistent image retention. Projects that demand colour reproduction, video-rate animation or touch interaction cannot be served by this monochrome passive panel. Buyers needing an integrated controller board or a larger active area should evaluate alternative modules.

400 × 168 pixel resolution

The 400 by 168 pixel grid defines the total information density available for text, icons or graphics. Every element must fit within this fixed matrix, so layout planning starts from this single constraint. Higher-detail dashboards or multi-line text displays will require a panel with more pixels.

Questions about this item

Does the 3-inch E-Paper panel need any periodic refreshing to maintain the image?

The display keeps the last content visible for a long time without power, so no periodic refresh is required once the image is set.

What limits how often I can update the 400 × 168 E-Ink screen?

Power is only drawn during a refresh, so the practical limit is the refresh cycle time of the panel itself.

How much heat or noise does the raw display produce during continuous operation?

With no backlight and power needed only while refreshing, the panel generates negligible heat and no audible noise.
