  • Brightness compensation apparatus and application method thereof
    Patent number: 8576258
    Abstract: For improving the brightness decay of a display due to its aging, a non-volatile memory such as Flash can be used to store a brightness accumulation value of each point of the display, and each point can be compensated for its brightness accordingly. However, the non-volatile memory suffers from incorrect write-in data or temporary power disconnection, and thus the error will exist all the time to make the display non-even. Hence, the present invention uses a multiple data backups and CRC error detection, plus new/old data comparison to protect data the non-volatile memory from incorrect brightness compensation value so as to uniform the brightness of the display.
    Type: Grant

  • Method for extending duration of a display apparatus having brightness compensation and apparatus realizing the same
    Patent number: 8379041
    Abstract: For improving the drawback of brightness decay of a display due to aging, a memory can be used to store the usage time of each pixel of the display, then based upon the usage time the brightness decay of each pixel of the display can be compensated and accordingly the value for the compensation can be stored in a volatile memory and a non-volatile memory. However, the usage of the non-volatile memory is limited. Hence, the present invention discloses a new approach for storing the data so as to decrease write-in sequence per unit area for the non-volatile memory rather than increasing its storing capacity proportionally.
