Abstract
A display module includes a scan line, a data line, a driving circuit and a level converting circuit. The driving circuit has at least one first driving unit and at least one second driving unit electrically connected to the first driving unit. A non-DC signal is transmitted between the first driving unit and the second driving unit for controlling the first driving unit and/or the second driving unit. The first driving unit outputs a first driving signal to the scan line. The second driving unit outputs a second driving signal to the level converting circuit. The level converting circuit is electrically connected with the driving circuit and the data line, and outputs a display signal to the data line according to the second driving signal. A driving method of the display module is also disclosed.
