Abstract

A protection circuit (), a power supply circuit, and a display panel. The protection circuit () comprises a feedback circuit () and a current adjusting circuit (). The reaction circuit () is used for receiving a supply voltage, adjust the first general resistance thereof according to the temperature of a data drive chip, and generate a reaction voltage according to the supply voltage and the adjusted first resistance. The current adjusting circuit () is used for receiving the supply voltage and the reaction voltage, and generate and output a driving current according to the reaction voltage and the supply voltage, the driving current decreasing following a rise in the temperature of the data drive chip; when the driving current is reduced, the thermal energy power consumption of the data drive chip is reduced so as to prevent burnout due to the temperature at the interior thereof being too high.
