Abstract
A display apparatus including a display panel is provided. The display panel has a plurality of display blocks, wherein each display block includes a light conversion circuit, a pixel array, and a data voltage selection circuit. The light conversion circuit receives the light pulse signal and has a pull-up circuit and a pull-down circuit, wherein the pull-up circuit and the pull-down circuit are coupled between a system high voltage and a system low voltage, and the pull-up circuit and the pull-down circuit output the system high voltage or system low voltage according to the light pulse signal to form a voltage pulse signal. The data voltage selection circuit is coupled to the light conversion circuit and the pixel array and receives an AC waveform voltage to supply a data signal to the pixel array according to the voltage pulse signal.
