Patent ID: 8115202

Claim:
An E-ink display device, comprising: a thin film transistor array substrate, comprising: a substrate; a plurality of scan lines formed on the substrate; a plurality of data lines formed on the substrate, a plurality of pixel areas on the substrate are defined by the scan lines and the data lines; a plurality of thin film transistors formed in the pixel areas and activated by the scan lines and the data lines; a plurality of pixel electrodes formed in the pixel areas and connected to corresponding thin film transistors; a plurality of testing signal lines serially connected to the scan lines and/or the data lines a plurality of testing switch devices formed between the testing signal lines and the scan lines or the data lines; and a testing control line serially connected to the testing switch devices to turn on or turn off the testing switch devices, wherein the testing signal lines comprises a scan testing signal line and a plurality of data testing signal lines, the scan testing signal line is serially connected to all scan lines and the data testing signal lines are serially connected to all data lines, any two data lines connected to one data testing signal line are not formed next to each other; an E-ink material layer formed on the pixel electrodes of the thin film transistor array substrate; a transparent cover formed on the E-ink material layer; and a transparent electrode layer formed between the transparent cover and the E-ink material layer.
