Research on field-sequential color LCD based on RGB Mini-LED backlight

As LCD televisions advance towards larger dimensions and ultra-high-definition resolutions, the issue of elevated energy consumption has become increasingly conspicuous. In pursuit of further power reduction, the industry has explored numerous avenues, including advancements in LCD panel transmittance and the integration of Local Dimming techniques. Amidst these efforts, the field-sequential color liquid crystal display (FSC-LCD) technology has garnered significant interest for its inherent power-saving attributes. Nonetheless, FSC-LCD technology has yet to attain mass production, partly hindered by the backlight's RGB LEDs' diminished luminous efficacy. This investigation introduces RGB Mini-LEDs as a replacement for conventional LEDs in the backlight system of FSC-LCDs. The research encompasses the experimental prototype's hardware design and assembly, leading to an energy efficiency index assessment. The outcomes reveal that the prototype successfully attains a top-tier energy efficiency rating, fulfilling the GB24850-2020 standards for a fourth-tier efficiency index applicable to 4K displays (3840*2160 resolution) and demonstrating substantial energy conservation capabilities.
