[0061] refer to figure 2 , the first embodiment of the method for spreading spectrum according to the present invention, the method for spreading spectrum includes:

[0062] Step S10, when a clock signal is detected, obtain a modulation signal corresponding to the clock signal;

[0063] In one embodiment, the liquid crystal display panel outputs a signal to the data driving chip and the gate driving chip through the timing control chip TCON, so that the data driving chip and the gate driving chip can drive and display according to the output signal. With the improvement of the display definition of the liquid crystal display panel, the data carried by the output signal also increases gradually. Therefore, the clock signal carried in the received display data will be split into two identical clock signals to The data driving chip and the gate driving chip are respectively controlled to drive and display according to the two clock signals. Since the two clock signals are iden...

Abstract

The invention discloses a method for spreading spectrum, comprising the following steps: when a clock signal is detected, acquiring a modulation signal corresponding to the clock signal; and performing spectrum spreading on the clock signal according to the modulation signal, wherein adjacent The modulation signal corresponding to the clock signal is an inverted signal. The invention also discloses a chip, a display panel and a computer-readable storage medium. The present invention controls two independent voltage-controlled oscillators to reversely spread the frequency of two adjacent clock signals by using two modulation signals that are mutually inverse signals, so that the frequency-spreading interval of the clock signal increases and the signal is distorted. The degree of frequency remains unchanged, which solves the technical problem that the spread spectrum effect of the dual clock signal is poor.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, a chip, a display panel and a computer-readable storage medium for spreading spectrum. Background technique [0002] With the improvement of people's living standards, large-size, high-resolution, high-frame-rate LCD panels are becoming more and more popular. The driving panel of the large-size LCD panel is outputted by TCON (Timing Controller, timing control chip), and transmits the signal to the data driver chip (Data driver) and the gate driver chip (Gate Driver) to control the LCD panel to drive and display. Nowadays, due to the improvement of the definition, the display data of the liquid crystal panel is getting larger and larger. In order to ensure that the valid data is transmitted within a limited time, when the TCON receives the display data sent by the front-end system, it will be received by the spread spectrum module. The received clo...
