Abstract

An apparatus and a method for sensing a display panel are provided. The apparatus includes a gate driving circuit and a sensing circuit. The gate driving circuit may scan the scan-lines during a plurality of scan-line periods within a frame period. The sensing circuit is coupled to a plurality of pixel circuits. A corresponding scan-line period of the scan-line periods is divided into a test data period and a display data period. In the test data period, the sensing circuit controls a corresponding pixel circuit to receive the test data, and the sensing circuit senses the electrical characteristic of the corresponding pixel circuit. In the display data period, the sensing circuit controls the corresponding pixel circuit to receive the display data from a corresponding data line, and the sensing circuit does not sense the corresponding pixel circuit.
