Bistable display panel and data driving circuit thereof

摘要

An exemplary data driving circuit for providing a display data voltage to a data line includes a data driving module. The data driving module includes a display data buffer unit and a switching element. The display data buffer unit is used to provide the display data voltage. The switching element is electrically coupled between the display data buffer unit and the data line and determines whether to allow the display data voltage provided by the display data buffer unit to be transmitted to the data line according to a control signal. Furthermore, the control signal controls the switching element to be turned off when the display data voltage provided by the display data buffer unit equals a predetermined voltage. Moreover, a display panel using the above data driving circuit also is provided.

主权项

1. A data driving circuit for providing at least one display data voltage to at least one data line, comprising:
at least one data driving module, the data driving module comprising: a display data buffer unit, for providing the display data voltage; and a switching element, electrically coupled between the display data buffer unit and the data line and subjected to the control of a control signal to determine whether to allow the display data voltage provided by the display data buffer unit to be transmitted to the data line; wherein the switching element is controlled by the control signal to be turned off when the display data voltage provided by the display data buffer unit is the same as a predetermined voltage, wherein the predetermined voltage is a target common voltage for the display data voltage in each image frame.
