  • Patent number: 9922606
    Abstract: The present invention provides a display driving circuit and a display device. The display driving circuit comprises a timing controller and a driving chip, and the timing controller comprises a first generation module and a first timing module. The first generation module is connected with the first timing module and the driving chip respectively, and configured to generate a row starting signal for triggering the first timing module to start timing and the driving chip which is idle to turn on. The first timing module is connected with the driving chip, and configured to trigger the driving chip which is idle in a non-effective pixel display duration to turn off, in case a current timing duration equals to an effective pixel display duration. The display driving circuit can prevent an idle driving chip from staying in the on-state and consuming power, so that current requirements for energy saving against a display device can be satisfied, and the quality of display device can be improved.(FIG.
