Round IPS 3.4″ DSI Capacitive Touch Display 800 × 800 for Raspberry Pi (C) - 3.4-DSI-TOUCH-C

Description

Round DSI display designed for applications that require a symmetrical screen format combined with multi-touch support in a compact form factor. The IPS panel with 800 × 800 pixels delivers high image detail, natural color reproduction, and wide 170° viewing angles, making it suitable for clear and readable user interfaces.

Image transmission is handled via a 2-lane MIPI DSI interface, enabling direct connection to compatible hosts without occupying GPIO pins. The integrated capacitive touch panel communicates over I2C and supports up to 10 touch points, depending on the operating system.

The front surface is protected by toughened glass (up to 6H hardness). Optical bonding reduces reflections, improves readability, and helps prevent dust ingress. The display offers brightness up to 300 cd/m², adjustable via software.

The display supports Raspberry Pi OS with 10-point touch, as well as RK3506, RK3576, and ESP32-P4 platforms with multi-touch and graphical interface support. Typical applications include smart home systems, in-vehicle devices, consumer electronics, and industrial equipment.
