The method for eliminating the water ripples caused by the spread spectrum comprises a database establishing step, an acquisition step, a first calculation step, a second calculation step, a third calculation step, a fourth calculation step, a segmentation step, an offsetstep and a circulation step. By adjusting the starting frequency points of different frames of spread spectrum, data charging is carried out in a cyclic frame, so that the problem of panel brightnessdifference caused by different charging electric quantities of different rows of data lines is solved, the display effect of the panel is improved, and meanwhile, the electromagnetic interference of the display equipment is reduced through spread spectrum signals.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the field of mobile device technology, and in particular to a method for eliminating water ripples caused by spread spectrum, a storage medium and a display panel. Background technique [0002] Spread spectrum (SSC) disperses the energy concentrated in the narrow frequency range to the set wide frequency range by means of frequency modulation, and reduces the electromagnetic frequency of the system by reducing the amplitude (energy) of the clock at the fundamental frequency and odd harmonic frequencies. The purpose of the radiation peak. Generally, digital clocks have very high peaks, that is, all energy is concentrated in a narrow frequency range, which is shown as relatively high energy peaks. On the spectrogram, it is easy to see that there is a high peak at the middle frequency, and a lower peak at the odd harmonic position; spread spectrum reduces the peak energy b...

AI Technical Summary

Problems solved by technology

On the spectrogram, it is easy to see that there is a high peak at the middle frequency, and a lower peak at the odd harmonic position; spread spectrum reduces the peak energy by increasing the clock bandwidth, reduces the peak of the clock, and reduces electromagnetic waves. The purpose of interference (EMI); but the current method of enabling spread spectrum, for the touch electrodes at different frequency points, the charging time of different lines is different. With the high resolution and high frame rate display technology requirements, the charging time Increasingly shrinking, the spread spectrum opens the touch electrode at different frequencies, the data output time is different, and water ripples are easy to occur
