The disclosure provides a touch detection method and apparatus for a touch display screen, wherein a time period for scanning the touch display screen within each frame comprises a display scanning phase and a touch scanning phase, the method comprising: scanning a part of the touch display screen during the touch scanning phase to detect whether there is a touch signal; and reducing a frame rate of the touch display screen and scanning the whole touch display screen when the touch signal is detected. Accordingly, the charging time of the panel is guaranteed while displaying and touch detecting functions are multiplexed.

Touch detection method and apparatus for touch display screen

A display panel, a display device and a method for repairing a disconnected line. The display panel comprises a lower substrate and a repair circuit. The lower substrate comprises data lines. The repair circuit comprises a proximal repair circuit, a distal repair circuit and an amplifier circuit. An input terminal of the amplifier circuit is electrically connect to a signal input terminal of a disconnected data line, and an output terminal of the amplifier circuit is electrically connect to a terminal of the proximal repair circuit and a terminal of the distal repair circuit respectively; another terminal of the proximal repair circuit is connect to a terminal of the disconnected data line that is close to the signal input terminal, and another terminal of the distal repair circuit is connect to a terminal of the disconnected data line that is away from the signal input terminal.
