摘要： A test method of a liquid crystal display panel is provided. The liquid crystal display panel includes a plurality of pixels and a testing pad. The pixels are disposed at intersections between a first, a second, and a third data lines and a plurality of scan lines. In the test method, each of the scan lines is driven to connect liquid crystal capacitors of the pixels to the first, the second, and the third data lines. A first and a second test voltages are respectively supplied to the first and the second data lines, wherein the first test voltage is not equal to the second test voltage. The first data line is floated. The floated first data line is measured through the testing pad to determine whether the liquid crystal capacitors of the pixels electrically connected to the first and the second data lines are electrically connected with each other.

摘要： A light detecting circuit and a light detecting method thereof are provided. The light detecting circuit includes a first resistor, a light sensor, a current source, and a first current mirror. The light sensor generates a corresponding photocurrent according to the illumination while being illuminated by the high brightness light beam. By dividing the photocurrent corresponding to the low brightness light beam from the photocurrent through the current source, the light detecting circuit can mainly detects the high brightness light beam, so that the detecting accuracy can be enhanced. Accordingly, when being applied to detect the high brightness light beam, the light detecting circuit can provide a sensing voltage in a wide enough range and a large enough sense scale, so that the sensing voltage is easy to be distinguished by the rear stage.
