Abstract

The embodiment of the invention provides a display driving method, a driving circuit and a display device. The display driving method comprises the following steps: detecting a data latch signal output to a data driving circuit by a time sequence control circuit; after a first data latch signal after startup is detected, the power supply circuit is controlled to output a common voltage to the pixel circuit; wherein the data latch signal is used for controlling a data driving circuit to output data voltage to the pixel circuit. According to the display driving method and the display driving circuit provided by the embodiment of the invention, the data latch signal TP is introduced into the power supply circuit as a condition for triggering the output of the common voltage, so that the common voltage Vcom and the data voltage Source output can synchronously enter the pixel circuit of the display area, and the problems of white flashing and ghosting during startup can be fundamentally solved.

Description

technical field [0001] Embodiments of the present application relate to the technical field of display driving, and in particular, to a display driving method, a driving circuit, and a display device. Background technique [0002] The liquid crystal display panel usually includes an array substrate, a cell-to-cell substrate, and a liquid crystal layer disposed between the two substrates. By adjusting the state of the liquid crystal layer according to the magnitude of the electric field applied to the liquid crystal layer, the transmittance of light is adjusted to achieve grayscale. order control. [0003] The power-on-off test is a common reliability test for liquid crystal display panels, and it is also an operation frequently involved by consumers. However, the existing liquid crystal display panel may have the problem of flickering white or afterimages at the moment of power-on. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of the embodiments of the p...
