20090009501 | Luminance sensing apparatus - The invention discloses a luminance sensing apparatus for sensing the luminance of any area on a panel. The luminance sensing apparatus comprises a base, a first shaft, a first actuator, a second shaft, a second actuator, and at least one luminance sensor. The first shaft is pivotally connected to the base, and the second shaft is pivotally connected to the first shaft. The luminance sensor is disposed on the second shaft. The first actuator is used for actuating the first shaft to rotate with respect to the base, and the second actuator is used for actuating the second shaft to rotate with respect to the first shaft, such that the luminance sensor on the second shaft is capable of sensing luminance of any area on the panel. Accordingly, the luminance on the panel can be uniformly calibrated. | 01-08-2009 |
