Abstract:
Provided are a driving circuit and driving method of a display panel and a display device. A drive voltage signal converted from an Nth-row data of current-frame data is inverted into an Nth-row data of previous-frame data relative to next-frame data and the Nth-row data of previous-frame data relative to next-frame data is cached, so that the Nth-row data of previous-frame data can be cached without using a double-data-rate synchronous dynamic random access memory.
