摘要： A light emitting diode (OLED) display and pixel driving method thereof are disclosed. Each storage capacitor is discharged via the driving TFT and OLED until conductive current of each OLED is almost zero so as to record a sum of a voltage drop across each OLED under a specific condition and the threshold voltage of the driving TFT. By using the sum of the voltage drop across each OLED and the threshold voltage of the corresponding TFT in the subsequent OLED driving process, the luminance reduction issue caused by TFT threshold-voltage shift and OLED material decay can be solved.

摘要： In a memory card and accessing method and accessing system for the memory card, the accessing method and accessing system are adapted to data access between a memory card and a machine using a first operation system. The accessing method firstly checks whether the data in the memory card is stored according to a data storage type supporting both the first operation system and a second operation system. When the data is not stored according to the data storage type, the machine is prohibited from accessing the memory card. A version value is stored in the memory card, wherein the version value is a value different from a predetermined version value. The second operation system deems the memory card un-accessible when the version value is confirmed to be not the predetermined version value.
