Embodiment Construction

[0024]The technical solutions of the present invention will be better understood by those skilled in the art, and the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025]Embodiments of the present invention provide a display driving method for driving the light emitting diode D1 display panel. The light-emitting diode D1 display panel is particularly, for example, an organic light emitting diode D1 display panel, quantum point light emitting diode D1 display panel.

[0026]Such asfigure 1 As shown, the light-emitting diode D1 display panel includes a plurality of gate lines G1, a plurality of data lines DL, a plurality of light-emitting control lines EML, and a plurality of pixel units. The pixel unit may be a matrix arrangement, and the gate line GL extends, for example, in the row direction, and the data line DL extends, for example, along the column direction, and the light-emitting control line EML extend, ...

Abstract

The invention provides a display driving method, a display driver and a display device. In the display driving method, a first driving signal is provided for a pixel unit connected with at least one grid line in at least one frame period of the pixel unit, wherein the frame period where the first driving signal is located is divided into a first writing stage, a first light-emitting stage and an extinguishing stage, and the first driving signal comprises the steps that in the first writing stage, effective voltage is provided for grid lines and all data lines, and invalid voltage is provided for light-emitting control lines corresponding to the grid lines so as to write data voltage into pixel units; in the first light-emitting stage, invalid voltage is provided for the grid lines, and effective voltage is provided for the light-emitting control lines corresponding to the grid lines, so that the pixel units emit light; and in the extinguishing stage, invalid voltage is provided for thelight-emitting control lines corresponding to the grid lines, so that the pixel units are extinguished. By applying the display driving method, the color cast of the light emitting diode display panel can be delayed, and the service life is prolonged.

Description

Technical field[0001]The present invention belongs to the field of display, and more particularly to a display driving method, a display driver, a display device.Background technique[0002]For the actuated diode display panel such as an organic light-emitting diode display panel or quantum dot light emitting diode display panel, the organic luminescent substance of different colors or the amount of quantum dot light-emitting substances of different colors is different from time to time. . For example, the life of blue organic luminescent substance is shorter than red and green organic luminescent substances. As used time, the organic light-emitting diode display panel will be yellow. Especially in the case where the lower grayscale (darker display screen) is more obvious. How to suppress the problem of color bias that exhibits the increase in the luminescent diode display panel, called the technical problem to be solved.Inventive content[0003]The present invention provides a display ...
