Abstract

The invention discloses an electronic ink display device and a repair method thereof, which are used for repairing a thin film transistor array substrate of the electronic ink display device. Each pixel unit of the thin film transistor array substrate is connected by a scanning wiring and a data wiring driving, and each pixel unit includes a thin film transistor and a pixel electrode. The repairing method firstly provides the thin film transistor array substrate, and then forms a repairing point on the defective pixel unit, the repairing point is located in the area above the scanning wiring, and the repairing point is used to electrically connect the pixel electrode and the scanning wiring.

Description

technical field [0001] The present invention relates to a display device and its repair method, in particular to an electronic ink display device and its repair method. Background technique [0002] The electronic ink (E-ink) used in the electronic ink display device (Electro Phoretic Display, EPD) is a liquid with multiple charged particles. Under the influence of an electric field, the charged particles move in the liquid, and the distribution state of these charged particles determines The display status of the electronic ink display device is shown. Since the charged particles have a similar specific gravity to the liquid, the charged particles remain stable when the electric field disappears. In addition, the electronic ink display device can adopt a reflective display method, so it does not need a backlight. Based on the above reasons, the electronic ink display device has the characteristics of power saving, and thus gradually attracts the public's attention. [000...
