Patent ID: 8797302

Claim:
A flexible display panel, comprising: a flexible substrate having a surface with a first display region, a second display region and a non-display region, the first display region being adjacent to the second display region and the non-display region surrounding the first display region and the second display region; a plurality of electro-phoretic pixel units disposed in the first display region of the surface of the flexible substrate, and each of the electro-phoretic pixel units comprising: a first reflecting layer; an electro-phoretic layer having a plurality of charged particles disposed above the first reflecting layer; a first pixel electrode disposed between the first reflecting layer and the electro-phoretic layer; and a first thin film transistor electrically connected with the first pixel electrode; a plurality of electro-wetting pixel units disposed in the second display region of the surface of the flexible substrate, and each of the electro-wetting pixel units comprising: a second reflecting layer; and an electro-wetting layer disposed above the second reflecting layer, wherein the electro-wetting layer comprises: a wall-based structure; a hydrophilic solution with electric conductivity or polarity filled in the wall-based structure; a hydrophobic solution undissolved with the hydrophilic solution filled in the wall-based structure under the hydrophilic solution; a second pixel electrode disposed between the second reflecting layer and the wall-based structure; and a second thin film transistor electrically connected with the second pixel electrode; a transparent protecting layer disposed on the plurality of electro-phoretic pixel units and the plurality of electro-wetting pixel units, wherein the electro-phoretic layer and the electro-wetting layer are sealed between the flexible substrate and the transparent protecting layer; and a driving circuit disposed in the non-display region of the flexible substrate, wherein the plurality of electro-phoretic pixel units and the plurality of electro-wetting pixel units are electrically connected to the driving circuit respectively, there is an interval formed between the electro-phoretic layer and the electro-wetting layer, and the transparent protecting layer covers the interval.
