Abstract: A timing controller device including a processor device and at least one storage device is provided. The processor device is configured to perform a data counting operation on a first image data according to a first look-up table to obtain a decay factor data and perform a compensation operation on a second image data according to the decay factor data and a second look-up table to obtain the first image data. The at least one storage device is configured to store different parts of the decay factor data. The processor device respectively stores the different parts of the decay factor data to the at least one storage device. A method for compensating an image data is also provided.

Abstract: A compensation method for pixel aging applicable to controlling circuit of a display device having a display panel is provided. The method includes: receiving a display content; predicting an aging of each of a plurality of pixels of the display panel resulting from the display content in order to obtain an aging prediction; generating a display data to compensate the display panel based on the aging prediction; and outputting the display content. Besides, a controlling circuit using the method for compensating a display device is also provided.

Abstract: An electronic device. A first operating mode (mobile phone) and a second operating mode (PDA) are provided by the electronic device. The electronic device has a host and a case. The host is provided with a first index portion. The case is disposed on the host for moving between a first position and a second position. When the case moves to the first position, the electronic device provides the first operating mode and partially covers the first index portion. When the case moves to the second position, the electronic device provides the second operating mode.
