Abstract
An LCD panel test apparatus for testing a liquid crystal display (LCD) panel of a notebook computer by a photo detector. The LCD panel test apparatus includes a base, a moving device, a rotary device and a clamping holder. The moving device is disposed on the base and is provided with a mounting portion for mounting the photo detector. The position of the photo detector can be changed by the movement of the moving device. The rotary device is disposed on the base. The clamping holder, for clamping the notebook computer, is disposed on the rotary device. The position of the notebook computer can be changed by the rotation of the rotary device and the clamping holder. Therefore, the LCD panel can be tested at different angles. As a result, the brightness testing of the LCD panel can be performed easily and accurately.
