Title:
DRIVING METHOD AND CIRCUIT FOR DISPLAY PANEL, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/051243
Kind Code:
A1
Abstract:
A driving method and circuit for a display panel (1), and a display apparatus. In the driving method for the display panel (1), a bandpoint voltage is first measured and a voltage difference between the bandpoint voltage and a common electrode voltage is calculated; and when the voltage difference between the bandpoint voltage and the common electrode voltage is less than a preset voltage difference, it is indicated that the display panel (1) has the problem of bright and dark lines, a data voltage waveform exhibits climbing, and the charging rate of blue pixels or green pixels is insufficient. At this time, by raising the bandpoint voltage, i.e., raising the charging voltage of red pixels, the charging loss during a climbing process is reduced, and the charging rate is improved, thus improving the bright and dark lines of the display panel (1), and enhancing the display effect.
