Abstract
Official abstract text for this publication.
A method for driving an organic light-emitting display includes controlling a GIP signal and a data signal during a bootup process of the organic light-emitting display to enable the organic light-emitting display to sequentially pass through an initialization state, a black state, and a normal display state, to prevent a screen flicker problem of the organic light-emitting display during booting.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for driving an organic light-emitting display, a bootup process of the organic light-emitting display sequentially comprising a first preset time period, a second preset time period, and a third preset time period, wherein the method comprises controlling a GIP (Gate in Panel) signal and a data signal that are continuously provided to a plurality of pixels of the organic light-emitting display from a start of the first preset time period, through the second preset time period, to an end of the third preset time period, so as to enable the organic light-emitting display to sequentially pass through an initialization state, a black state, and a normal display state, wherein the organic light-emitting display is initialized during the first preset time period, and wherein a pixel positive voltage and a pixel negative voltage are provided to a plurality of pixels in the second preset time period, wherein, in the first preset time period, the data signal is set to a high-impedance state, and the GIP signal is set to an active output state; in the second preset time period, the data signal is set to a black state, and the GIP signal is kept in the active output state; and in the third preset time period, the data signal is set to a normal display state, and the GIP signal is kept in the active output state. 2. The method for driving an organic light-emitting display according to claim 1 , wherein each of the first preset time period, the second preset time period and the third preset time period is longer than a duration of one frame. 3. The method for driving an organic light-emitting display according to claim 1 , wherein the pixel positive voltage and the pixel negative voltage start to be provided to the plurality of pixels in the second preset time period simultaneously. 4. A method for driving an organic light-emitting display, a bootup process of the organic light-emitting display sequentially comprising a first preset time period, a second preset time period, and a third preset time period, wherein the method comprises controlling a GIP (Gate in Panel) signal and a data signal that are continuously provided to a plurality of pixels of the organic light-emitting display from a start of the first preset time period, through the second preset time period, to an end of the third preset time period, so as to enable the organic light-emitting display to sequentially pass through an initialization state, a black state, and a normal display state, wherein the organic light-emitting display is initialized during the first preset time period, wherein a pixel positive voltage and a pixel negative voltage are provided to a plurality of pixels in the second preset time period, wherein in the first preset time period, the data signal is set to 0 V, and the GIP signal is set to an active output state; in the second preset time period, the data signal is set in the black state, and the GIP signal is kept in the active output state; and in the third preset time period, the data signal is set to a normal display state, and the GIP signal is kept in the active output state. 5. The method for driving an organic light-emitting display according to claim 4 , wherein each of the first preset time period, the second preset time period, and the third preset time period is longer than a duration of one frame. 6. The method for driving an organic light-emitting display according to claim 4 , wherein the pixel positive voltage and the pixel negative voltage start to be provided to the plurality of pixels in the second preset time period simultaneously.
