Product Introduction

DESCRIPTION

HICENDA The SPI AMOLED 2.4-inch display module integrates a 450(RGB) × 600 resolution panel, delivering up to 800 cd/m² brightness and driven by the RM690B0 IC. Supporting SPI, MCU, and MIPI interfaces, and equipped with a touch panel, this module combines full-color rendering, wide viewing angles, and high contrast performance within a compact mechanical structure, making it suitable for a wide range of embedded and intelligent display applications.

GENERAL SPECIFICATION

Overview of Display Architecture

The module adopts a rigid AMOLED structure, which ensures mechanical robustness while maintaining the intrinsic advantages of organic light-emitting technology. Each pixel is self-emissive, eliminating the need for a backlight and enabling precise luminance control.

With a pixel arrangement of 450(RGB) × 600 and a pixel pitch of 81.6 μm, the display achieves a density of 311 PPI. This specification supports fine image rendering and smooth graphical transitions, particularly beneficial in compact human-machine interfaces.

Key Structural Characteristics

· Self-emissive AMOLED technology for high efficiency

· Full-color depth with 16.7 million colors (24-bit)

· Symmetrical viewing characteristics with unrestricted viewing direction

· Integrated capacitive touch panel for interactive functionality

 

Electrical and Optical Performance

The RM690B0 driver IC provides a stable and flexible control platform, supporting multiple interface protocols including SPI, MCU, and MIPI. This versatility simplifies system integration across different hardware architectures.

The display achieves a luminance level of 800 cd/m², ensuring readability under various ambient lighting conditions. Combined with an ultra-high contrast ratio of 100,000:1, the module delivers deep blacks and vivid color reproduction.
