摘要： A display apparatus includes sub-pixels, at least one gate line group and a scan drive circuit. The gate line group includes a first gate line, a second gate line and a third gate line. The scan drive circuit outputs, in a frame scan cycle, a first scan signal to the first gate line, a second scan signal to the second gate line, and a third scan signal to the third gate line in sequence. Durations of effective scan periods of the scan signals are equal. A start moment of the effective scan period of the second scan signal is delayed by a first time length compared with that of the first scan signal. A start moment of the effective scan period of the third scan signal is delayed by a second time length less than the first time length compared with that of the second scan signal.

摘要： A method for driving a display panel, a display drive device, and a display device. The method includes, during a data refresh stage of at least one display frame, loading a gate turn-on voltage to a gate line, and loading, on each data line, a data voltage of an image to be displayed, so that each sub-pixel inputs a corresponding data voltage, and during a blanking time period, loading a gate turn-off voltage to a gate line, and loading a compensation voltage to each data line. When a data voltage in a sub-pixel connected to a data line is greater than a common electrode voltage, a compensation voltage is less than the data voltage in the sub-pixel connected to the data line, and/or when the data voltage in the sub-pixel is less than the common electrode voltage, the compensation voltage is greater than the data voltage in the sub-pixel.

摘要： The present application discloses an electronic device including a housing, support plates and a display panel. The housing is recessed inward to form one or more clearances penetrating the housing along a first direction. A number of the support plates is at least two, and one clearance is correspondingly arranged below adjoining parts of two adjacent support plates. The support plates are configured to support the display panel. The display panel is switchable between a folded position and an unfolded position. When the display panel is in the unfolded position, first surfaces of the support plates that abut against the display panel are flush. When the display panel is in the folded position, any two oppositely folded and adjacent support plates are separated by a part of the display panel that covers the any two oppositely folded and adjacent support plates when the display panel is in the unfolded position, and a part of the any two oppositely folded and adjacent support plates and a part of the display panel that covers the part of the any two oppositely folded and adjacent support plates when the display panel is in the unfolded position enter the clearance.
