摘要： The embodiment of the present disclosure discloses a system and a method for loading and unloading a cassette. The system for loading and unloading the cassette comprises: a lifting device configured to vertically ascend and descend between a first height and a second height; a first conveying device mounted in the lifting device and configured to move the cassette in a horizontal direction; a second conveying device mounted at the first height and configured to move the cassette in a horizontal direction; a third conveying device mounted at the second height and configured to move the cassette in the horizontal direction; a plurality of first position sensors configured to detect a position of the lifting device; and a control device configured to control ascending and descending of the lifting device, and adjust a further rising or falling of the first conveying device in the lifting device based on an initial stop position of the lifting device detected by the first position sensor such that the first conveying device is aligned with the second conveying device at the first height, or is aligned with the third conveying device at the second height. The conveying device of the lifting device and the conveying device on the platform are capable to accurately align with each other so as to achieve the smooth loading and unloading of the cassette.

摘要： Provided are an AMOLED pixel unit circuit, a driving method thereof and a display panel for realizing the threshold voltage compensation. The AMOLED pixel unit circuit includes: a light emitting module; a driving module configured to drive the light emitting module; a light emitting control module configured to control the light emitting module to emit light; a threshold compensation module configured to perform threshold voltage compensation for the driving module; a data voltage writing module configured to input a data voltage to the driving module; and an initialization module configured to initialize the threshold compensation module. The threshold voltage compensation is realized by modifying the pre-charging fashion to fixedly set the gate of the driving TFT to be at a data level lower than the high level such that the subthreshold saturation cutoff state is reached before the drain-source voltage becomes zero in the compensation stage.
