The SPI controller operates in synchrony with a liquid-crystal display (LCD) vertical scan position in order to update the current settings for rows of LEDs in parallel with the updating of nearby rows of LCD pixels. When updating a row of LEDs, the SPI controller executes one or more SPI transactions included in an SPI program to write current settings for multiple LEDs nearly simultaneously. A compiler generates the SPI program based on the topology of LEDs included in the display device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques for updating light-emitting diodes in synchrony with liquid-crystal display pixel refresh","description":"A display controller within a display device includes a serial peripheral interface (SPI) that coordinates the updating of current settings for groups of light-emitting diodes (LEDs).
