Abstract
A thin film transistor array substrate suitable for being applied in an electronic ink display device is provided. The thin film transistor array substrate includes a substrate, scan lines, data lines, thin film transistors, pixel electrodes and testing signal lines. The data lines and the scan lines are disposed and define a plurality of pixel regions on the substrate. Each thin film transistor is disposed in the respective pixel region and driven by the corresponding scan line and data line. In addition, each pixel electrode is disposed in respective pixel region and electrically connected to the thin film transistor corresponding thereto. Furthermore, the testing signal line connects to the scan lines and/or the data lines in series. The testing accuracy as well as the production yield of the electronic ink display device and the thin film transistor array substrate can be improved by the design of the aforementioned testing circuit.
