  • Patent number: 11837138
    Abstract: A control circuit for a low-temperature poly-silicon array controls the low-temperature poly-silicon array including M rows×N columns of pixel units. The control circuit includes N operational amplifiers, a comparison unit, and a pixel input switch control unit. The comparison unit determines pixel values of N red subpixels, N green subpixels, and N blue subpixels in at least one row of pixel units of the M rows of pixel units are the same as each other. The pixel input switch control unit controls, when the pixel values of the N red subpixels, the N green subpixels, and the N blue subpixels in the at least one row of pixel units of the M rows of pixel units are the same as each other, the N red pixel input switches, the N green pixel input switches, and the N blue pixel input switches to be all turned on.
