Display panel repair method, display panel and display

A display panel repair method for repairing a broken data line of a display panel, wherein the display panel comprises:

• a substrate;
• a plurality of data lines arranged on the substrate and extending in a column direction, for transmitting data signals;
• at least one repair line arranged on the substrate and overlapped with at least part of the plurality of data lines, for connecting with a broken data line when the broken data line with a breakpoint exists in the plurality of data lines, to repair the broken data line;
• at least one compensation line arranged on the substrate, and each compensation line being connected to the at least one repair line through a resistor;
• and
• a data driver comprising a plurality of first output channels connected to the plurality of data lines, at least one second output channel connected to an end of the at least one repair line away from the resistor and at least one third output channel connected to an end of the at least one compensation line away from the resistor, the data driver being configured to input data signals to the plurality of data lines, the at least one repair line and the at least one compensation line;
• wherein when a magnitude of the data signal input to the at least one compensation line by the data driver is less than the data signal input to the at least one repair line by the data driver, the at least one repair line leaks electricity to the at least one compensation line through the resistor to accelerate a voltage drop speed of the at least one repair line:
• when a magnitude of the data signal input to the at least one compensation line by the data driver is greater than a magnitude of the data signal input to the at least one repair line by the data driver, the at least one compensation line leaks electricity to the at least one repair line through the resistor;
• wherein one or more of the plurality of data lines is the broken data line, the broken data line being divided by the breakpoint into a first sub-data line connected to the data driver and a second sub-data line disconnected from the data driver, wherein the display panel repair method comprises:
• connecting the second sub-data line to the at least one repair line;
• configuring the magnitude of the data signal output by the data driver to the at least one compensation line connected to the at least one repair line to be less than a magnitude of a current row data signal, when a magnitude of a previous row data signal input to the at least one repair line by the data driver is greater than a magnitude of the current row data signal;
• and
• configuring the magnitude of the data signal output by the data driver to the at least one compensation line connected to the at least one repair line to be greater than the magnitude of the current row data signal, when the magnitude of the previous row data signal input to the at least one repair line by the data driver is less than the magnitude of the current row data signal.

A display, comprising:

• a display panel;
• and
• a backlight module arranged opposite to the display panel and configured to provide backlight for the display panel;
• wherein the display panel comprises:
• a substrate;
• a plurality of data lines arranged on the substrate and extending in a column direction, for transmitting data signals;
• at least one repair line arranged on the substrate and overlapped with at least part of the plurality of data lines, for connecting with a broken data line when the broken data line with a breakpoint exists in the plurality of data lines, to repair the broken data line;
• at least one compensation line arranged on the substrate, and each compensation line being connected to the at least one repair line through a resistor;
• and
• a data driver comprising a plurality of first output channels connected to the plurality of data lines, at least one second output channel connected to an end of the at least one repair line away from the resistor and at least one third output channel connected to an end of the at least one compensation line away from the resistor, the data driver being configured to input data signals to the plurality of data lines, the at least one repair line and the at least one compensation line;
• wherein when a magnitude of the data signal input to the at least one compensation line by the data driver is less than the data signal input to the at least one repair line by the data driver, the at least one repair line leaks electricity to the at least one compensation line through the resistor to accelerate a voltage drop speed of the at least one repair line:
• when a magnitude of the data signal input to the at least one compensation line by the data driver is greater than a magnitude of the data signal input to the at least one repair line by the data driver, the at least one compensation line leaks electricity to the at least one repair line through the resistor.
