A display driving circuit structure with spike reduction is provided, comprising an operational amplifier circuit, a switching element and an output inductor. The operational amplifier circuit includes a first terminal receiving an input signal and an inverting terminal. The switching element has a first end electrically connected with the operational amplifier circuit and a second end opposite to the first end. The output inductor is electrically connected between the second end of the switching element and an output node, where an output signal is generated and provided. By employing the generated output signal to drive a display panel, the spike voltage of the output signal can be significantly reduced, and as a result, the operating temperature of the display panel can be effectively reduced by at least 4° C. It is believed that the present invention is beneficial to maintaining both low complexity and process cost of the driver ICs.
