CPC classification number: G09G3/3466 , G02B26/001 , G09G2300/0473 , G09G2310/027 , H03K3/012 , H03M1/002 , H03M1/68 , H03M1/765 , H03M1/806
Abstract: This disclosure provides systems, methods and apparatus for providing an output voltage to be used in a display device. In one aspect, a circuit may include switches and a digital-to-analog converter (DAC). A charge recycling circuit may include a capacitive voltage divider providing voltage supplies for the switches to select from and provide to the DAC. A storage capacitor may be configured to be coupled one at a time and in parallel with individual capacitors of the capacitive voltage divider. The storage capacitor may store charge that may be reused. Additionally, a data control circuit may provide control signals for the switches and the DAC.
