Detecting Circuit, Detecting Method and Display Device

摘要

The present invention provides a detecting circuit, a detecting method and a display device, and the detecting circuit includes data signal input buses, switching units and control units, wherein the data signal input buses are used to provide data signals to the data lines and a predetermined number of data lines corresponding to a central region of the display panel constitute a first data line group; the switching units are arranged between the data lines and corresponding data signal input buses, all of which are divided into two switching unit groups, and all switching units in correspondence with the data lines in the first data line group constitute a first switching unit group; and the control units are used to control all switching units of corresponding switching unit groups to be turned on or turned off simultaneously.

主权项

1. A detecting circuit used to perform a detection of crosstalk on a display panel, comprising:
a plurality of data signal input buses, which are used to provide data signals to corresponding data lines on the display panel, a predetermined number of data lines corresponding to a central region of the display panel constituting a first data line group; a plurality of switching units, which have the same number as the data lines and correspond to the data lines one to one, the switching units being arranged between the data lines and corresponding data signal input buses, being used to control electrical connections between the data lines and the corresponding data signal input buses, all switching units being divided into at least two switching unit groups, and all switching units in correspondence with the data lines in the first data line group constituting a first switching unit group; and a plurality of control units, which have the same number as the switching unit groups and correspond to the switching unit groups one to one, and are used to control all switching units of corresponding switching unit groups to be turned on or turned off simultaneously.
