This work presents a new pixel circuit designed on glass by using hydrogenated amorphous silicon (a‐Si:H) technology for polymer‐stabilized blue‐phase liquid crystal (BPLC) display with vertical field switching (VFS) mode. In the VFS mode, the driving voltage of BP‐LC can be reduced, moreover, the hysteresis and residual birefringence are effectively suppressed as well. From the simulation results, the average error rate of storage voltage in pixel circuit is below 5.14% while operating frequency is 180 Hz.
