The light emitting device array includes plural light emitting devices arranged in plural scan lines and plural data lines. In one frame, plural scan line switch circuits respectively electrically connect plural scan nodes in plural corresponding scan lines to a scan conduction voltage in a non-overlapping sequential order. Data line buffer circuits of the driver circuit provide predetermined dimming levels to corresponding data nodes respectively according to data operation signals. A pre-discharge control amplifier circuit of the driver circuit is coupled to the plural scan nodes and provides a pre-discharge level to at least one predetermined scan node during a predetermined pre-discharge time period according to a pre-discharge signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting device array circuit capable of reducing ghost image and driver circuit and control method thereof","description":"A light emitting device array circuit capable of reducing ghost image includes: a light emitting device array, plural scan line switch circuits, and a driver circuit.
