Abstract
A driving circuit and a display device are disclosed. The driving circuit includes a driving chip, a first controllable switch and a resistor. A first lead pin of the driving chip is connected with a second terminal of the first controllable switch, a control terminal of the first controllable switch receives a switching signal, and a first terminal of the first controllable switch is connected with a display region through the resistor. When the driving circuit is under a voltage-dividing operation mode by the resistor, the switching signal is at a low voltage level, the first controllable switch is conductive, and the resistor performs a voltage-dividing, and the display region displays a first type of colors in order to increase the number of the displayed colors so that the delicate degree, aesthetics and layering of a displayed image can be improved.
