Abstract
The impact of pixel leakage current and liquid crystal flexoelectric effect on flicker were studied with simulation and measurement methods. The impact rule of pixel architecture, TFT voltage, electrode design, liquid crystal material, driving signal, and other factors is obtained, and the key factors under different conditions are identified. The pixel design and liquid crystal mixture development scheme under different conditions are proposed, and a strategy of data voltage modulation at the blanking period combined with frequency-wise ACC brightness compensation is established to reduce flicker. Based on the proposed total flicker optimization scheme, flicker lower than -50 dB is achieved on 55/65/75 in. products when swapping between 48/120 Hz every 200 ms, meeting the G-Sync flicker standard.
期刊介绍：
The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
