Abstract

The invention relates to a signal modulation method and device and a display device. The signal modulation method comprises the following steps: providing a pulse width modulation signal; setting theoutput frequencies of a plurality of signals to be modulated by referring to the frequency of the pulse width modulation signal; determining the output interval time of a plurality of signals to be modulated according to the duration time of the pulse width modulation signal at the high potential; and modulating each to-be-modulated signal according to the determined output frequency and the output interval time and then outputting the modulated signal. According to the invention, the output frequencies of the plurality of signals to be modulated are set by using the pulse width modulation signal; the output interval time of a plurality of signals to be modulated is determined by using the duration time of the pulse width modulation signal at the high potential, so that a storage circuit originally used for storing the data can be omitted, the number of pins of a related circuit is reduced, and the cost of the GOA circuit is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a signal modulation method, device and display device. Background technique [0002] With the development of display technology, display devices are widely used due to their advantages of high image quality, power saving, thin body, and narrow frame. sense of experience. In order to narrow the frame of the display device, GOA (Gate driver on Array, array substrate gate drive integration) technology has emerged. GOA technology is a technology that can directly make the gate drive circuit around the display panel, which can reduce the production process. , and can reduce product costs, improve panel integration, and achieve narrow borders. [0003] In GOA technology, it is usually necessary to boost the input clock signal to obtain a higher voltage, and then output the boosted clock control signal to the GOA circuit according to the corresponding delay, so that the GOA...
