Power supply circuit for liquid crystal display device |
摘要 |
A power supply circuit of a liquid crystal display device includes a first positive polarity charge charging unit including a first capacitor connected to positive and negative power terminals through switches to charge a charge, a second positive polarity charge charging unit including a second capacitor connected to the positive power terminal and a ground terminal through switches to charge a charge, a first positive polarity charge loading unit loading the charge supplied through the positive power terminal to a negative polarity terminal, a second positive polarity charge loading unit loading the charge charged in the first capacitor to a negative polarity terminal, a third positive polarity charge loading unit loading the charge charged in the second capacitor, and a positive polarity charge charging/loading control unit outputting charging control signals with a same phase to the switches, and periodically or irregularly changing durations of the charging and loading control signals. |
