Driving method of scanning line of plane monitor

Abstract

The invention is suitable for the technical field of plane monitor, providing a driving method of scanning line of the plane monitor. The method comprises the following steps: generating a gate frequency signal having a first group frequency and a second group frequency; generating a gate initiating signal having two pulse waves; orderly generating the multiple gate signals for controlling multiple scanning lines according to the gate frequency signal and the gate initiating signal; each gate signal has two pulse waves; covering the first gate signal for the pulse waves among the first group frequencies according to the enabling signals and outputs the gate signal at the pulse wave of the second group frequency; and starting the two scanning lines from the multiple scanning lines according to the multiple gate signals. The driving method of the invention can shorten the time of the scanning and the charging, reducing the mixed color among the colors and increasing the color saturation and the color saturation, enhancing the image definition.

Description

technical field [0001] The invention belongs to the technical field of flat-panel displays and provides a method for driving scanning lines of the flat-panel displays. Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram of a flat panel display in the prior art. The flat panel display 10 includes a gate driver 12 , a source driver 14 and a display panel 16 . The flat panel display is an active matrix flat panel display (AMLCD), an organic light emitting diode display (OLED) or a plasma display (PDP). The display panel 16 includes a plurality of pixels 18, the plurality of pixels 18 are electrically connected to the gate driver through a plurality of scan lines (scan lines) G1, G2, . . . line) S1, S2, . . . , SN are electrically connected to the source driver. A plurality of scan lines are electrically cross-connected with a plurality of data lines, the pixels 18 are turned on by the scan lines, and the data potentials are input by ...

AI Technical Summary

Problems solved by technology

The prior art flat panel display 10 can only drive one scan line at the same time, but cannot drive two or more scan lines at the same time.

[0005] When the gate driver 12 performs the above-mentioned scanning operation, not only must there be enough time to charge or discharge the capacitance of the pixel 18, but also the source driver 14 must have enough time to output data. If the scan line is activated quickly before the output of the data is completed, unexpected image values ​​will be written to the capacitance of the pixel 18, resulting in attenuation of the image displayed on the flat panel display 10.

Another similar situation is that when there is not enough time to charge the capacitance of the pixel 18, the capacitance of the pixel 18 will be insufficiently charged, and the picture will also fade
