Driving circuit, method for determining connection information of driving circuit and display device

A method for determining connection information of a driving circuit, wherein the driving circuit comprises:

• a gamma chip configured to provide a plurality of initial binding point voltages;
• and a data driving chip comprising a processor and a plurality of operational amplifiers, output terminals of the operational amplifiers being correspondingly connected to terminals on the processor and being further connected to their own inverting input terminals;
• wherein the method comprises:
• acquiring, by a processor of a computer device, currents corresponding to the initial binding point voltages outputted by the gamma chip;
• determining, by the processor of the computer device, whether the currents are greater than a preset driving current;
• when the currents are less than the preset driving current, determining, by the processor of the computer device, that the output terminals of the gamma chip corresponding to the currents are a first type of output terminals, and generating, by the processor of the computer device, first connection information that makes the first type of output terminals of the gamma chip correspondingly connected to non-inverting input terminals of one part of the operational amplifiers;
• when the currents are greater than the preset driving current, determining, by the processor of the computer device, that the output terminals of the gamma chip corresponding to the currents are a second type of output terminals, and generating, by the processor of the computer device, second connection information that makes the second type of output terminals of the gamma chip correspondingly connected to inverting input terminals of the other part of the operational amplifiers and makes non-inverting input terminals of the operational amplifiers grounded;
• wherein the preset driving current is a current representing driving capability required for driving a display panel, and an output terminal of the data driving chip is connected to the display panel.
