Array substrate of electronic paper, manufacturing method thereof and electronic paper

Abstract

The invention provides an array substrate used for electronic paper. The array substrate comprises a plurality of signal emission lines, a plurality of sensing signal lines and a plurality of photosensitive thin film transistors, wherein the source electrodes and the drain electrodes of the photosensitive thin film transistors are arranged on the sensing signal lines, the signal emission lines are connected with the grid electrodes of the photosensitive thin film transistors, and an active layer of each photosensitive thin film transistor corresponds to the gap between every two adjacent points of electronic ink in the electronic paper in position. The invention further provides a manufacturing method of the array substrate and the electronic paper comprising the array substrate. The photosensitive thin film transistors are additionally arranged on the array substrate of the electronic paper, so that touch and control operation on the electronic paper is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate of electronic paper, a manufacturing method thereof, and an electronic paper including the array substrate. Background technique [0002] Existing electronic paper generally includes an array substrate and a transparent electrode substrate facing each other, and electronic ink arranged between the array substrate and the transparent substrate. Thin film transistors are arranged on the array substrate, and the thin film transistors control the electric field between the pixel electrodes and the common electrodes. When the electric field is negative, the white ions in the e-ink are shown above, and when the electric field is positive, the black ions in the e-ink are shown above. However, the current electronic paper does not have a touch function, which affects the performance of the electronic paper. [0003] Therefore, how to enable the electronic p...
