Display system line extraction abnormal display cancelling method and its circuit

Abstract

The invention relates to a method for eliminating the abnormal display of the thread drawing phenomenon for a display system and a circuit thereof, which comprise the following steps: an image data line is input into a driving circuit and the driving circuit grasps the image data line to be deleted and the time pulse signal displayed by the image data line to be deleted on a display is eliminated; the circuit enables the signal for a grid driving integrated circuit to which a control switching element corresponds. The invention utilizes the driving circuit to generate a control waveform so as to effectively eliminate a plurality of displayed data lines, thereby converting the format of an image system into the format of another different image system. The invention can effectively reduce the interference caused by the grounding disturbance of the circuit and ensure that the panel avoids generating the bad phenomenon after the thread drawing.

Description

technical field [0001] The invention relates to a method for eliminating abnormal display of a display system and a circuit thereof, in particular to a method for eliminating abnormal display of a line-drawing phenomenon of a display system and a circuit thereof. Background technique [0002] The analog data format received by the drive system at the front of the flat panel display panel is the data format of the TV system. The receiving interface of the analog signal is usually the AV terminal (YC mixed signal) and S terminal (YC separated signal), and the current TV system is applicable There are three international standards for the data format, National Television Standards Committee (NTSC), Phase Alternating Line (PAL) and Sequential Color Avec Memory (SECAM). [0003] The front-end drive system of small and medium-sized flat-panel displays mostly supports two transmission standards, NTSC and PAL. The NTSC system transmits 30 frames per second, a total of 60 fields, and...

That is to say, the line drawing algorithm of the timing control circuit is to delay the display of the previous data H8 of the data to be extracted, that is, to display after the pre-extracted data passes, and to delay the previous data of the data to be extracted. When the data H8 is displayed, the signal AVSS disturbance will affect the sampled voltage, because the voltage of this data line remains in the circuit for a longer time than other data lines, and the signal AVSS disturbance will cause a greater impact on the voltage of this line. Affected by this, the lines at the drawing line are obviously different from other lines, resulting in abnormal display screen, as shown in Figure 6
