  • Publication number: 20240233663
    Abstract: Disclosed are a method for adjusting a signal of a display panel, a time controller integrated circuit, a display panel, and a storage medium. The method includes: converting first data into a first data voltage signal using a first data voltage, in response to a set condition being reached, sending the first data voltage signal to a chip on film integrated circuit, the chip on film integrated circuit identifies the first data voltage signal to obtain a second data; acquiring the second data from the chip on film integrated circuit, determining that the chip on film integrated circuit fails to identify the first data in response to the second data being different from the first data; and adjusting the first data voltage until a second data voltage signal converted from the first data using a second data voltage after adjustment being successfully identified by the chip on film integrated circuit.

  • 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.
