The present disclosure provides a method for displaying a display panel which includes determining corresponding register values of selected groups of thin film transistors according to respective characteristics of the thin film transistors at different temperatures; writing the register values into a system; adopting, by the system, the corresponding register value according to a working temperature. Therefore, the system will select and adopt the corresponding register value from a register according to a real-time working temperature of the display panel, thereby reducing shift of optical parameters of a liquid crystal screen and improving displays of the screen.
