Abstract:
1. A system for displaying images, comprising: a display device, comprising: a data line operative to provide display signals and sweep signals; a scan reset line operative to provide scan reset signals; a first capacitor having a first end coupled to the data line, the first capacitor being operative to store charges from the data line; a first inversion unit having an input end coupled to a second end of the first capacitor, a first supply end coupled to a first voltage source, a second supply end coupled to a second voltage source larger than the first voltage, and an output end; a second inversion unit having an input end coupled to the output end of the first inversion unit and an output end; a first reset switch having a first end coupled between the second end of the first capacitor and the input end of the first inversion unit, a second end coupled to the output end of the first inversion unit, and a control end coupled to the scan reset line; a second reset switch having a first end coupled to the input end of the second inversion unit, a second end coupled to the output end of the second inversion unit, and a control end coupled to the scan reset line; a driving thin film transistor (TFT) having a control end coupled to the output end of the second inversion unit; and an illuminating unit coupled between a first end of the driving TFT and a third voltage source larger than or equal to the first voltage source.
