Abstract
A display device includes a substrate, a driving circuit, an E-paper display layer and a protective coating layer. The driving circuit is arranged on the substrate. The E-paper display layer is disposed on and driven by the driving circuit. The protective coating layer is coated on and in contact with the E-paper display layer. The protective coating layer can provide protection and better optical performance, and it is advantageous to the manufacturing method to overcome the problems such as bubbles and low light transmittance occurring in the conventional manufacturing method.
Claims20
A display device, comprising:
- a substrate;
- a driving circuit, formed on the substrate;
- an E-paper display layer, formed on the driving circuit;
- and
- a protective coating layer, directly formed on the E-paper display layer by coating instead of adhering and in contact with the E-paper display layer without bubbles between the protective coating layer and the E-paper display layer.
A method for manufacturing a display device, comprising
- steps of:
- providing a substrate;
- forming a driving circuit on the substrate;
- forming an E-paper display layer on the driving circuit;
- and
- forming a protective coating layer on the E-paper display layer directly by coating instead of adhering, the protective coating layer being in contact with the E-paper display layer without bubbles between the protective coating layer and the E-Paper display layer.
