Application

Design takeaway

When designing electronic devices, select display technologies (e.g., OLED for small screens, LCD for large screens) that align with the intended size and brightness requirements to minimize energy usage.

How to apply

When specifying displays for a new product, create a matrix comparing the power consumption of different technologies (e.g., OLED, LCD, e-paper) at various sizes and typical brightness levels relevant to the product's use case.

Project actions

  • 01When researching display options for a design project, look for data on power consumption per unit area or per unit of brightness.
  • 02Consider how the user will interact with the display (e.g., always-on vs. intermittent use) as this affects overall energy impact.

Paragraph starter

The choice of display technology significantly influences a device's overall energy consumption. Research indicates that while OLED displays offer superior power density for smaller screen sizes, Liquid Crystal Displays (LCDs) become more energy-efficient for larger displays. This suggests that designers should carefully consider the intended screen size when selecting display technology to optimize power management and extend battery life in their products.
