Abstract
The disclosure discloses a display drive circuit, a display device, and a method for driving the same, where the display drive circuit includes a control circuit arranged between a power supply management circuit and a level conversion circuit, and the control circuit is configured to boost a standard gate turn-on voltage signal provided by the power supply management circuit, and to generate and then output a higher gate turn-on voltage signal to the level conversion circuit, upon determining that an ambient temperature is below a set temperature, and/or an output of a gate drive circuit of a display panel is abnormal, so that the level conversion circuit generates and then outputs a corresponding gate drive signal at higher voltage.
