In an LED display, which outcome occurs when the drive current exceeds the rated forward current?

💡 Explanation

Thermal runaway occurs because increased current leads to higher junction temperature, enhancing carrier generation through increased electron-hole pair density; therefore, destructive positive feedback happens rather than stabilized performance at nominal settings or spectral adjustments absent the current constraint.
