Publication number: 20100045585Abstract: A method for eliminating deficient image on a liquid crystal display (LCD) is provided. The method is used for eliminating the deficient image generated during the shutdown period in a normally white LCD. The method comprises the following steps. First, when a power indication signal changes from a first state to a second state, a black frame is displayed in a first period of time. At the end of the first period, a white frame is displayed in a second period of time. At the end of the second period, the supply of a negative scan voltage is stopped and a white frame is displayed in a third period of time. At the end of the third period, the power is turned off.Type: ApplicationFiled: November 6, 2009Publication date: February 25, 2010Applicant: NOVATEK MICROELECTRONICS CORP.Inventors: Wei-Chih Wang, Yi-Te Liu
