Thyristor-Controlled Light Emitting Component for Reliable Self-Scanning Arrays

The invention segments the semiconductor device into distinct functional regions: a light emitting element region with p-n junctions for light emission, and a transfer element region with p-n-p-n structures for control functions. This spatial segmentation allows independent optimization of light emission characteristics and driving characteristics while maintaining a single integrated semiconductor layer laminate, thus resolving the contradiction between device complexity and reliability.

The invention introduces thyristors as intermediary control elements between the signal source and the light emitting elements. These thyristors with p-n-p-n structure act as mediators that provide reliable switching control without the rectifying characteristic issues that plague direct diode connections. The thyristors enable precise driving control while eliminating erroneous operations caused by rectifying characteristics.

The invention applies local quality by providing reference potential specifically to the control electrodes of the thyristors in the transfer element region, rather than uniformly to all elements. This localized reference potential supply simplifies the driving control of the thyristor-based transfer elements while avoiding the rectifying characteristic malfunctions that would occur if reference potential were supplied directly to the light emitting diodes. Each region receives the appropriate electrical configuration for its specific function.
