Micro LED Emission Pulse Compensation for Temperature-Stable Luminance

The patent applies preliminary action by pre-establishing linear function graphs that represent the relationship between on-pulse width and luminance at different temperatures. These graphs are generated in advance through measurements at first and second temperatures, and then used to determine the target linear function graph for temperature compensation without requiring real-time complex calculations during operation.

The patent utilizes parameter changes by adjusting the on-pulse width of the emission signal based on the determined target linear function graph. The processor modifies the pulse width parameter in response to temperature variations, leveraging the pre-established relationship between pulse width and luminance to maintain consistent optical performance across different temperature conditions.

The patent performs luminance measurements at different temperatures in advance to establish linear function graphs before actual operation. This preliminary measurement phase allows the system to capture the relationship between on-pulse width and luminance at various temperatures, storing this information for later use during temperature compensation without requiring repeated measurements during operation.

The patent implements periodic action by conducting measurements at discrete temperature points (first temperature, second temperature, and target temperature) to generate corresponding linear function graphs. This periodic measurement approach at key temperature intervals provides sufficient data for accurate compensation while minimizing the total measurement time compared to continuous monitoring.
