DISPLAY DRIVER AND FLICKER SUPPRESSION DEVICE THEREOF |
摘要 |
A flicker suppression device applied in a display driver for preventing the output image data of the display driver from being affected by an electrostatic discharge (ESD) event is provided. The flicker suppression device includes an ESD detector and an output stage controller. The ESD detector is coupled to a first power wire of the display driver for determining whether an ESD level shift event occurs to the first system reference voltage signal on the first power wire. If so, a control signal corresponding to the first level is provided. The output stage controller controls the output stage circuit of the display driver to be in a high impedance state in response to the control signal corresponding to the first level to avoid the output stage circuit outputting an output image data that has been affected by an ESD event.
