4. A display control circuit is characterized by comprising a main control chip and a display chip, wherein the main control chip comprises a generation unit and a first interface; the display chip comprises a second interface, a storage unit and a third interface;
the generating unit is used for generating a first image;
the generating unit is connected with the first interface, and the first interface is used for sending the first image;
the first interface is connected with the second interface, the storage unit is respectively connected with the second interface and the third interface, the storage unit is used for storing the first image, the third interface is used for continuously outputting the first image to a display screen based on a first frame rate under the condition that the second interface does not receive the second image sent by the main control chip, and the first frame rate is determined based on the screen refreshing frequency range of the display screen.
5. The display control circuit of claim 4,
the generating unit is further used for generating a second image, and the first interface is further used for sending the second image;
the third interface is further configured to output image data to the display screen based on a second frame rate when the second interface receives the second image sent by the first interface, where the image data includes the second image, and the second frame rate is greater than the first frame rate.
6. The display control circuit of claim 5,
the generating unit is specifically configured to generate the first image or the second image when layer update information is detected.
7. A display control method applied to the display control circuit according to any one of claims 4 to 6, the method comprising:
the method comprises the steps that a main control chip generates a first image and sends the first image to a display chip;
and under the condition that the display chip does not receive the second image sent by the main control chip, continuously outputting the first image to the display screen based on a first frame rate, wherein the first frame rate is determined based on the screen refreshing frequency range of the display screen.
8. The method of claim 7, wherein after the display chip continuously outputs the first image to the display screen based on the first frame rate, the method further comprises:
the main control chip generates a second image and sends the second image to the display chip;
and the display chip outputs image data to the display screen based on a second frame rate under the condition of receiving a second image sent by the main control chip, wherein the image data comprises the second image, and the second frame rate is greater than the first frame rate.
9. The method of claim 8, wherein the master control chip generates the first image, comprising:
the main control chip generates the first image under the condition of detecting the layer updating information;
the master control chip generates a second image, including:
and the main control chip generates the second image under the condition of detecting the layer updating information.
10. An electronic device, comprising a display screen and the display control circuit of any one of claims 1 to 3, wherein the display screen is connected to a display chip in the display control circuit, and the display screen is configured to display the first image.
11. An electronic device, comprising a display screen and the display control circuit of any one of claims 4 to 6, wherein the display screen is connected to a display chip in the display control circuit, and the display screen is configured to display the first image.
