Abstract

A non-volatile display module has a display panel and a driving circuit. The display panel has a substrate at which at least one scan line, at least one data line and at least one thin film transistor (TFT) are disposed. The TFT is located at an intersection area of the scan line and data line. The driving circuit has a driving unit, a power converting unit and a multiplexing unit. The driving unit receives at least one image controlling signal according to a clock signal. The power converting unit generates a plurality of power signals. The multiplexing unit is electrically connected with the scan line, the data line, the driving unit and the power converting unit, and outputs one of the power signals to the scan line or the data line according to the image controlling signal. A non-volatile display apparatus is also disclosed.
