SCANNING LIGHT-EMITTING DEVICE WITH INCREASED LIGHT INTENSITY

A scanning light-emitting device with increased light intensity includes a light-emitting circuit and a shift circuit including a plurality of shift thyristors, a plurality of diodes and a plurality of shift signal lines. The plurality of shift thyristors is divided into a plurality of groups at intervals. Each of the shift signal lines is electrically connected to the shift thyristors belonging to one of the groups. The light-emitting circuit includes a plurality of light-emitting thyristors and a plurality of light-emitting control lines. Each of the light-emitting thyristors is correspondingly electrically connected to one of the shift thyristors. Each of the light-emitting control lines is electrically connected to the light-emitting thyristors electrically connected to the shift thyristors belonging to one of the groups. The total light-emitting intensity can be increased through partial overlap during light-emitting of the light-emitting thyristors in adjacent groups.
