Methods and apparatus relating to wireless remote control are described. A photoresist layer is coated over the first and second color filters and the third color pixel region. When the key-input is invalid, the changing section changes the key-input to another key-input. The cell address enable unit receives an anti-fuse repair address to enable a cell address of an anti-fuse cell to be repaired upon receiving the data mask signal outputted from the data mask signal input circuit. In one embodiment, the method comprises comparing a permissible bandwidth usage with a data transfer rate to produce a comparison result and adjusting the data transfer rate for performing at least one data transfer operation based on the comparison result. The passivation of the flake material virtually eliminates subsequent corrosion from exposure to moisture.
