Abstract: A flexible display, including a stand, a supporting mechanism, a flexible screen, a driving component, a driven component, and a link, is provided. The supporting mechanism is connected to the stand. The flexible screen is attached to the supporting mechanism. The driving component is disposed on the stand. The driven component is disposed on a side of the supporting mechanism distant from the stand. The link has a first end and a second end opposite to the first end. The first end is connected to the driving component, and the second end is connected to the driven component. The driving component drives the driven component through the link to move on a first horizontal plane to drive the supporting mechanism and the flexible screen to transform when the driving component moves between the first horizontal plane and a second horizontal plane that is parallel to the first horizontal plane.

Abstract: A filter structure includes a base and a filter. The base is provided with an aperture and multiple second slopes around the aperture. The filter is connected to the base and slidable relative to the base. The filter has a first sliding block and multiple second sliding blocks. The first sliding block passes through the aperture. Each second sliding block abuts against each second slope and is slidable along each second slope. Therefore, the gap between the main body and the filter may be reduced to increase the filtering efficiency of the air purifier and the filter structure.

Abstract: An airflow-generating device which can adjust an air chamber volume and a method applied thereto are provided. The device has a volume-adjustable air chamber and an airflow-generating unit. The volume-adjustable air chamber has an inlet structure, an outlet structure, and an adjustment unit. A deflector structure for adjusting pressure or direction of airflow is arranged in the outlet structure, and an air chamber space is formed between the inlet structure and the outlet structure. The adjustment unit is used to adjust an inlet-outlet distance between the inlet structure and the outlet structure for adjusting the volume of the air chamber. The airflow-generating unit is arranged in the volume-adjustable air chamber and used to generate the airflow introduced from the inlet structure into the air chamber space and exhausted from the outlet structure. The present disclosed example can increase the intensity or reduce the noise of the airflow.

Abstract: A centrally-controlled correlation system for testing a correlation wafer and comparing the testing results with the wafer's reference data that has been determined previously. The testing instructions and the correlation criteria are stored and transmitted from a central database. Such centrally-controlled correlation system improves the reliability of the correlation results and reduces the time to correlate a correlation wafer.

Abstract: A system and method thereof for test time forecasting. The system comprises a storage device and a first program module. The storage device stores Circuit Probing (CP) test records individually storing information regarding a test time and a yield of a test unit corresponding to a test program. The first program module receives the CP test records and generates a new test time forecast model according to the CP test records. The new test time forecast model determines a dependent variable corresponding to the test time by utilizing an independent variable corresponding to the yield.
