  • Publication number: 20180182305
    Abstract: The present disclosure relates to a storing method of compensation data of liquid crystal devices (LCDs) and a data compensation device. The storing method includes obtaining a target compensation data of a target display area, comparing a data range of the target compensation data and a storable data range of a predetermined storing space to determine a shift amount, adopting an adjusting process to the target compensation data with the shift amount to obtain the storing compensation data fitting the storable data range, and storing the shift amount and storing the compensation data. In this way, not only the precision of the data compensation may be enhanced, but also the mura issue may be effectively eliminated without increasing the volume of the flash and the cost.
