Display Interface Selection
The three different interfaces represent three distinct technical paths and market positions, allowing for optimal selection based on project requirements.
RGB Interface (RTL8721F) - High Integration and Performance
Advantages:
High Integration: Chip integrates LCD Controller, Image Processing Engine, and MJPEG decoder. No external IC needed, compatible with a wide range of RGB screens.
Simple Development: Mature software drivers shorten development cycles and enable rapid mass production.
Good Display Performance: Supports higher resolution (e.g., 800x480), higher refresh rates, and richer color performance for a better user experience.
Applicable Solutions:
Smart Home Appliance Panels (Refrigerators, AC Units, Washing Machines, etc.)
Basic Smart Control Panels
Two-Wheeler Dashboards
Consumer Electronics (Portable Medical Devices, Smart Speakers with Display)
MIPI DSI Interface (RTL8730E) - High Performance
Advantages:
High Bandwidth: MIPI DSI 2-lane (up to 1Gbps per lane), supports very high resolutions (e.g., 720p and beyond) and high refresh rates for smooth display effects.
Strong Anti-Interference: Differential signaling is more suitable for complex electromagnetic environments and longer transmission distances.
Powerful Compute: Dual-core Cortex-A32 1.2GHz can run Linux/FreeRTOS, decode H.264 video (720p), handling stunning UIs and complex applications.
Applicable Solutions:
High-End Smart Home Hubs
High-End Smart Robots
Streaming Media Display Devices
QSPI Interface (RTL8721Dx) - Ultimate Cost-Effectiveness
Advantages:
Ultra-Low Cost: Integrates image processing engine, requires very few QSPI wires, reducing PCB design complexity and connector cost.
Low Power Consumption: Ideal for battery-powered devices or those extremely sensitive to power consumption.
Saves Pins: Frees up more GPIOs for connecting other sensors and peripherals.
Applicable Solutions:
Electronic Shelf Labels (ESL) / Smart Labels
Smart Home Sensor Panels
Low-Power Smart Meters
Software Support
A comprehensive SDK provides a full-stack software solution from chip to system to cloud, supporting FreeRTOS, Linux, and Zephyr operating systems, helping brands realize highly competitive “user-friendly” smart terminals.
