AI Technical Summary
Technical Problem
There is only one compensation table for the overdrive technology in the prior art, which cannot effectively improve the charging rate, especially when the polarity is reversed, the charging difference is significant.
Method used
According to whether there is polarity switching between rows, different compensation tables are selected for row overdrive compensation, which is compatible with grayscale and polarity changes, and balances charging differences.
Benefits of technology
By selecting different compensation tables, the picture quality problems caused by insufficient charging can be better solved and the problem of poor fine lines caused by uneven charging can be improved.

Abstract
The invention provides a driving method of a display panel and related equipment. The method comprises the following steps: determining whether the polarities of data voltages of two pixel units which are in adjacent rows and are connected with the same data line are the same or not; in response to determining that the polarities are the same, searching a data voltage compensation value from the first compensation table to compensate the data voltage of the next row of pixel units in the two adjacent rows of pixel units connected with the same data line; in response to determining that the polarities are different, searching a data voltage compensation value from a second compensation table to compensate the data voltage of the next row of pixel units in the two adjacent rows of pixel units connected with the same data line; driving the next row of pixel units based on the compensated data voltage; wherein the data voltage compensation value searched from the second compensation table is greater than the data voltage compensation value searched from the first compensation table.
