  • Publication number: 20220301468
    Abstract: A control method of a display apparatus is provided. The method includes: obtaining to-be-displayed data; starting to generate first image data of a first display panel based on the to-be-displayed data; sending image data to a second processing component based on the to-be-displayed data; and after generating the first image data, delaying sending the first image data to the first display panel based on a first difference between second duration taken by the second processing component to generate second image data and first duration taken by a first processing component to generate the first image data.
