Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Fig. 1 is a cross-sectional view of an electronic paper display 1 with long-term display.

The long-acting display electronic paper display 1 comprises a backlight source 2, an electronic paper display screen 3, a touch screen 4 and a driving circuit (not shown in the attached drawings), wherein the backlight source 2, the electronic paper display screen 3 and the touch screen 4 are sequentially laid, and the driving circuit is used for detecting the touched position of the touch screen 4 and driving the electronic paper display screen 3 to display a corresponding picture. The whole outer part of the above parts is also covered with a shell 5.

The electronic paper display screen 3, the touch screen 4 and the driving circuit all adopt the existing technical scheme, such as the technical scheme recorded in "CN 101373305B".

The electronic paper display screen 3 comprises a sub paper lower substrate 31, microcapsules 32 and an electronic paper upper substrate 33 which are sequentially laid, wherein pixel electrodes are arranged on the upper surface of the electronic paper lower substrate 31, common electrodes are arranged on the lower surface of the electronic paper upper substrate 33, and the microcapsules 32 are fixed between the common electrodes and the pixel electrodes through adhesives.
