摘要： The present application discloses a circuit for providing a temperature-dependent common electrode voltage. The circuit includes a sensing sub-circuit coupled between a power-supply terminal and a ground terminal and configured to generate a first voltage for controlling a switching sub-circuit to connect the power-supply terminal to a first node. The circuit further includes a compensation sub-circuit coupled between the first node and the ground terminal and be enabled, when the first voltage decreases below a threshold as temperature increases above a threshold temperature, to output a temperature-dependent second voltage proportional to the temperature to a second node. Additionally, the circuit includes an output sub-circuit coupled to the second node combined with a first input-voltage terminal and further coupled to a second input-voltage terminal, to generate a temperature-dependent output voltage based on a weighted mixing of the temperature-dependent second voltage, a first input voltage, and a second input voltage.
