Abstract

Embodiments of the present invention include a display panel for the blind, a method for manufacturing the same and a display device for the blind. The display panel for the blind includes an array substrate, a touch substrate and an elastic film. The array substrate includes a glass substrate and data lines and gate lines formed on the glass substrate. The data lines and gate lines intersect each other so as to form pixel units, with each of the pixel units including a pixel electrode. The touch substrate includes a flexible film layer and charged columnar structures provided on the flexible film layer. The elastic film layer is provided between the array substrate and the touch substrate. The side of the touch substrate on which the charged columnar structures are formed faces the side of the array substrate on which the pixel electrodes are formed, and the charged columnar structures on the touch substrate correspond to the pixel electrodes on the array substrate one to one.

First claim
