Review on driving method for low power consumption of TFT-based display screens

TFT的低功耗特性能够减少电子设备的能量消耗,从而达到节省能源、延长电池寿命、降低使用设备温度、提高显示质量的目的。因此,低功耗TFT在电子设备的设计和制造中具有十分重要的作用。TFT基板的结构有很多种类,通常可分为一般型、高温多晶硅型、低温多晶硅型、金属氧化物半导体型和柔性材料基板型。本文对现有的TFT基板显示器件的低功耗研究进行总结分析,主要包括两大方面:对TFT基板本身驱动进行优化;对TFT基板外设驱动进行优化。本文对两大方面的低功耗研究进行了综述,并对近年来国内外TFT低功耗方法研究进行详细介绍。根据所介绍的方法的特点与其尚未攻克的困境,对TFT基板显示设备低功耗驱动的未来发展进行了展望。

The low power consumption TFT can reduce the energy consumption of electronic devices,save energy,extend battery life,reduce device temperature,and improve display quality,which plays an important role in the design and manufacturing of electronic devices.The structure of TFT substrates can be divided into following types:high-temperature polycrystalline silicon,low-temperature polycrystalline silicon, metal oxide semiconductor, and flexible material substrate. This article summarizes and analyzes the research on low power consumption of existing TFT substrate display devices, including two main aspects: optimizing the driving of TFT substrate itself and optimizing the driving of TFT substrate peripherals. The research of low power consumption TFT in recent years at home and abroad is introduced in detail. Based on the characteristics and challenges of the methods introduced, the future development of low power consumption driving for TFT substrate display devices is discussed.
