The present invention has a pixel which includes a first switch, a second switch, a third switch, a first resistor, a second resistor, a first liquid crystal element, and a second liquid crystal element. Therefore, little friction and resistance is encountered when force fitting a pivot-bearing assembly into the upper portion of the stepped inner bore, thereby avoiding surface damage and the generation of unwanted debris particles. Accordingly, the media file format based on an ISO base media file can effectively store and reproduce stereoscopic contents. A state transition of the input threshold switch is detected and a value indicative of a number of cycles of charge transfer required to reach the state transition is determined. One adaptive logical block is stored in one adaptive metablock.
