Abstract:
1. A voltage stabilizing circuit of a display driver integrated circuit comprising: a capacitor having a first electrode selectably connected to a first input voltage node through a first switch during a first time period and not during a second time period and having a second electrode selectably connected to a second input voltage node through a second switch during the second time period and not during the first time period, the first input voltage node being connected to a first voltage generator and the second input voltage node being connected to a second voltage generator, wherein a first stabilized voltage is output at a first output voltage node that is directly connected to the first electrode while the first switch connects the first electrode to the first input voltage node and while the second switch connects the second electrode to ground, wherein a second stabilized voltage is output at a second output voltage node that is directly connected to the second electrode while the second switch connects the second electrode to the second voltage node and while the first switch connects the first electrode to ground, wherein the first switch connects the first electrode to one of the first input voltage node and ground alternately, and wherein the second switch connects the second electrode to one of the second input voltage node and ground alternately.
