Abstract

The invention provides a power supply management chip and a driving method and a driving system thereof. The power supply management chip comprises a register, a signal receiving module and a processing module, wherein the register is used for storing first voltage data, the signal receiving module is used for acquiring second voltage data, and the processing module is used for detecting the firstvoltage data and the second voltage data and rewriting data in the register into the second voltage data when the first voltage data is different from the second voltage data; after the signal receiving module receives the second voltage data, the first voltage data and the second voltage data are detected through the processing module, thereby preventing the first voltage data from being changedand causing the abnormality of a display image, and solving a technical problem that a conventional power management chip causes the abnormality of a display panel image because the data is changed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a power management chip, a driving method and a driving system thereof. Background technique [0002] The existing power management chip can output signals to the display panel, but due to the production problem of the power management chip, the data will be changed, resulting in differences in the data transmitted to the display panel, causing abnormalities in the display screen. [0003] Therefore, the existing power management chip has the technical problem that the data is changed, resulting in an abnormal picture of the display panel. Contents of the invention [0004] The invention provides a power management chip, a driving method thereof, and a driving system, which are used to solve the technical problem that the data of the existing power management chip is changed, resulting in an abnormal display panel picture. [0005] In order to solve the above problems, the te...
