AI Technical Summary
Technical Problem
In existing technologies, aging compensation methods for OLED displays cause sudden aging of the displays, resulting in poor display quality and failing to meet users' replacement cycles.
Method used
By setting up memory in the application processor to store screen attribute parameters in the order of sector usage, the number of writes to any sector in the memory is reduced, the duration of display compensation is extended, and a brightness compensation model is used for accurate display compensation.
Benefits of technology
It extends the aging compensation time of the display screen, improves the display quality, reduces the number of writes to the memory, saves the component cost of the FPC, and provides more space for other electronic components.

Abstract
本申请实施例提供数据存储方法和装置，涉及终端技术领域。该方法包括：应用处理器从DDIC中获取第一参数，从存储器的第一存储位置开始对第一参数进行存储，存储器设置在应用处理器中；DDIC利用第一参数对显示屏进行显示补偿；应用处理器从存储器的第二存储位置开始对第二参数进行存储，第一存储位置与第二存储位置不同；DDIC从存储器中获取第二参数，并利用第二参数对显示屏进行显示补偿。这样，电子设备也可以按照扇区的使用顺序将屏幕属性参数依次写入到存储器中的不同扇区中，减少存储器中任一扇区的写入次数，进而提高数据的总写入次数，延长显示屏显示补偿的时长。
