OLEDs offer superior contrast and faster response times but may suffer from burn-in. LCDs are generally more cost-effective and offer better longevity for static, high-brightness applications.

Technical selection guide for integrated graphic display modules
What are Display Modules - LCD, OLED, Graphic components?
Graphic display modules are integrated assemblies used to provide visual feedback in embedded systems. Selection hinges on interface protocol (SPI/I2C/Parallel), power budget, ambient lighting conditions, and the specific controller IC requirements for your host processor.
How to Choose Display Modules - LCD, OLED, Graphic Components
Selecting the right display module requires balancing visual performance with system constraints.
Interface Protocol
Match the module's interface (SPI, I2C, RGB, or Parallel) to your MCU's available peripherals and bandwidth needs.
Display Technology
Choose OLED for high contrast and wide viewing angles, or LCD (TFT/STN) for cost-effective, sunlight-readable applications.
Controller Integration
Verify if the module includes a built-in display controller (e.g., ILI9341) to offload rendering tasks from the host MCU.
Environmental Specs
Check operating temperature ranges and IP ratings if the display is intended for industrial or outdoor environments.
Power Consumption
Evaluate peak current during full-screen updates versus sleep-mode power draw for battery-powered designs.
