Publication number: 20140347411Abstract: There is provided a driving method for a display, which includes a display unit and a phase modulation unit. The display unit includes a plurality of pixel rows and generates image signals having a polarization direction. The phase modulation unit includes two oppositely disposed electrodes and an LC layer sandwiched between the two electrodes. The driving method changes a potential difference provided on the two electrodes of the phase modulation unit to control the twist of the LC layer thereby changing the polarization direction of the image signals generated by the display unit and passing through the phase modulation unit.Type: ApplicationFiled: August 8, 2014Publication date: November 27, 2014Inventors: Heng-Cheng TSENG, Ra-Bin LI, Mu-Kai KANG
