Waveshare 4inch IPS Capacitive Touch Display 480x480
Description
Waveshare LF40-480480-ARK is a compact 4-inch IPS capacitive touch display with 480 × 480 resolution, designed for Luckfox Pico Ultra and Luckfox Pico Ultra W RGB screen projects. It uses a parallel RGB LCD interface and RGB666 data transmission, making it suitable for embedded UI, compact dashboards, and touch-based control interfaces.
This Waveshare 4inch IPS capacitive touch display integrates a GT911 touch chip, 400cd/m² brightness, and a square display layout that works well for device status panels, icon-based control pages, and round-style UI compositions. It is a practical module for developers building small smart terminals and embedded HMI systems on Luckfox platforms.

Other Content
The LF40-480480-ARK is built for RGB screen workflows on Luckfox Pico Ultra series boards. In the official RGB screen setup, image data uses RGB666. The provided image defaults to 720×720 in the shared example workflow, and for 480×480 resolution screens the display setting can be switched by pressing the development-board BOOT button after startup as documented in the official RGB screen guide.
For practical development, the 480×480 square format is often easier to use than narrow rectangular displays when building compact control pages, quick setting panels, and center-focused instrumentation layouts. The Luckfox Pico Ultra W shown in example images is for reference only and is not included.
