Solution Approach 1:

The sub-pixel is divided into two light-emitting units connected in series through a light-transmitting layer. Each unit can be independently controlled, allowing the display module to reduce energy consumption by activating only necessary units while maintaining the required color output, thus resolving the energy consumption issue without excessive complexity increase

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The light-transmitting layer serves multiple functions: it electrically connects the two light-emitting units in series while simultaneously allowing light to pass through with high transmittance. This multi-functionality reduces the need for additional separate components, thereby managing device complexity while achieving energy savings
