Abstract: Disclosed are a light source system and control method thereof, as well as a display device and control method thereof. The light source system comprises: an array light source, comprising M illuminants with independently adjustable brightness; an optical switch, arranged on an emergent optical path of the army light source, for guiding illumination light emitted by the M illuminants to N sub-regions of a preset light region; and a control device for controlling an optical switch to adjust at a preset frame rate the direction of the illumination light emitted by at least part of the M illuminants, and guiding the illumination light emitted by at least part of the illuminants to sub-regions different from the previous one or more image frames of the current image frame.

Abstract: Provided is an array light source. The array light source includes light-emitting modules, a wavelength conversion apparatus configured to convert excitation light into excited light, a control apparatus configured to transmit a light modulation signal, and a light modulation apparatus configured to modulate the excited light based on the light modulation signal, emit the modulated light, and form a modulated image. Each light-emitting module is configured to emit the excitation light. The light-emitting modules include edge light emitting modules distributed along an edge of the array light source and center light-emitting modules surrounded by the edge light-emitting modules. A maximum luminous intensity of the edge light-emitting modules is greater than that of the center light-emitting modules.
