Zusammenfassung:	A display screen (1132) frequency conversion method, a DDIC chip (1131), a display screen module (1130), and a terminal (1100). The method comprises: initializing a display screen parameter according to a first refresh frequency (401); upon the receipt of first image data sent from an AP, performing image scanning according to the first refresh frequency (402); if second image data sent from the AP is not received within a preset delay duration of a vertical front porch (VFP) corresponding to the first refresh frequency, adjusting the first refresh frequency to a second refresh frequency, the second refresh frequency being lower than the first refresh frequency (403); and adjusting the display screen parameter according to the second refresh frequency (404). The DDIC chip (1131) adaptively adjusts the refresh frequency of the display screen (1132) according to the speed of image data transmission by the AP, so as to achieve the adaptive dynamic frequency conversion of the display screen (1132), thereby reducing the power consumed by the display screen (1132).
