P‐8: A Novel Design for a Pixel‐Driver Circuit with Boost Function for UWFR Display

Abstract

In this paper, a novel design of pixel driver circuit with boost function for UWFR (Ultra wide frame rate) display is introduced. The design is appropriate for the high‐resolution and high frame rate display to overcome the shortage of charging time. The circuit can improve the the Ion of the driver TFT by promoting the Vgs of the TFT in AA to promote the charging performance without any higher Voltage of the power supply. An UWFR LCD panel with proposed circuit is fabricated, and the dynamic frame rate ranging from 5Hz to 120Hz could be achieved. The charge ratio of the panel with the optimum circuit in 120Hz is promoted by 6% compared with the normal design, and the boosted voltage of the Vgs in active area is also detected.
