It can be understood that the present embodiment is different from the previous embodiment in that the light emitting directions of the first backlight 17 and the second backlight 18 are different. In this embodiment, the light emitting directions of the first backlight 17 and the second backlight 18 are away from the side of the electronic paper substrate 1a, i.e. toward the inner side wall of the first accommodating space 151 of the package 15. Therefore, the reflective coating 1g needs to be disposed on a side surface of the package 15 adjacent to the first backlight 17 and/or the second backlight 18 in the direction perpendicular to the stacking direction, that is, the reflective coating 1g is disposed on an inner sidewall of the first receiving space 151, so that light emitted from the first backlight 17 and the second backlight 18 can be reflected into the electronic paper substrate 1a.

In one possible embodiment, please refer to fig. 2 and fig. 10 together, fig. 10 is a schematic cross-sectional view of an electronic paper display panel according to an embodiment of the present application. The reflecting member 14 is disposed on a side surface of the electronic paper substrate 1a facing away from the substrate 13, or on a side surface of the electronic paper substrate 1a adjacent to the substrate 13.
It can be understood that, in this embodiment, as shown by the dashed arrow in fig. 2, when the reflecting member 14 is disposed on the surface of the side of the electronic paper substrate 1a facing away from the substrate 13, most of the light can be incident to the reflecting member 14 from the direction of the side of the reflecting member 14 adjacent to the electronic paper substrate 1a, so that the reflecting member 14 can effectively reflect the light toward the side of the display assembly 1b, and the arrangement mode makes the light utilization rate higher; in contrast, as shown by the dashed arrow in fig. 10, when the reflecting member 14 is disposed on the side surface of the electronic paper substrate 1a adjacent to the substrate 13, a portion of light is incident on the reflecting member 14 from two sides perpendicular to the stacking direction, and accordingly, the reflecting member 14 reflects the portion of light back along the direction perpendicular to the stacking direction, but cannot reflect toward the side where the display assembly 1b is located, so that the light utilization rate is lower than that of the arrangement in which the reflecting member 14 is disposed on the side surface of the electronic paper substrate 1a facing away from the substrate 13, but since the reflecting member 14 is disposed on the side surface of the electronic paper substrate 1a adjacent to the substrate 13, that is, disposed inside the electronic paper substrate 1a, the reflecting member 14 can be effectively protected from abrasion.
It will be appreciated that the reflecting member 14 may be selectively disposed on a side surface of the electronic paper substrate 1a facing away from the substrate 13, or on a side surface of the electronic paper substrate 1a adjacent to the substrate 13, according to practical situations, which is not limited in this application.
In one possible embodiment, please refer to fig. 11, fig. 11 is a schematic cross-sectional view of an electronic paper display panel according to another embodiment of the present application. The electronic paper display panel 1 further comprises a protective layer 1h, wherein the protective layer 1h is arranged on one side of the reflecting piece 14, which is away from the electronic paper substrate 1a, and is used for protecting the reflecting piece 14.
It will be appreciated that, when the reflecting member 14 is disposed on a side surface of the electronic paper substrate 1a facing away from the substrate 13, as shown in fig. 11, the reflecting member 14 may be worn, so as to affect the light reflection effect, thereby resulting in poor display effect of the electronic paper display panel 1. Therefore, in this embodiment, the protective layer 1h is disposed on the side of the reflecting member 14 away from the electronic paper substrate 1a, and the protective layer 1h is wrapped on the reflecting member 14, so as to achieve the purpose of protecting the reflecting member 14, ensure that the reflecting member 14 has a good reflection effect of reflecting light toward the side of the display assembly 1b, and improve the display effect of the electronic paper display panel 1.
In one possible embodiment, the material of the electronic paper substrate 1a includes any one or more of glass, polymethyl methacrylate (PMMA), methyl methacrylate styrene copolymer (MS), polystyrene (PS), or Polycarbonate (PC).
It can be understood that the electronic paper substrate 1a is used as a light guide plate of the first display panel 11 and the second display panel 12, and the electronic paper substrate 1a is used as a carrier plate of the display assembly 1b in the first display panel 11 and the second display panel 12, which itself needs to have a characteristic of being capable of reflecting light, and also needs to have a certain supporting strength. Therefore, in the present embodiment, the material of the electronic paper substrate 1a includes any one or more of glass, polymethyl methacrylate (PMMA), methyl methacrylate styrene copolymer (MS), polystyrene (PS), and Polycarbonate (PC).

The electronic paper display panel 1 further comprises an anti-reflection layer 1i, wherein the anti-reflection layer 1i is arranged on one side of the reflection piece 14, which is away from the electronic paper substrate 1a.
It will be appreciated that the light emitted by the first backlight 17 and the second backlight 18 propagates in the electronic paper substrate 1a, and may not be totally reflected by the reflecting member 14 toward the side of the display unit 1 b. In this embodiment, in order to improve the light utilization rate, the anti-reflection layer 1i is disposed on a side of the reflecting member 14 away from the electronic paper substrate 1a, so that a portion of the light that is not reflected to the reflecting member 14 can be reflected back into the electronic paper substrate 1a for reflection and propagation, until the light is reflected to the reflecting member 14, and is reflected by the reflecting member 14 toward a side of the display assembly 1b, thereby improving the light utilization rate.

It can be understood that, in this embodiment, by multiplexing the electronic paper substrate 1a as the light guide plate of the electronic paper display panel 1, the screen thickness of the electronic paper display panel 1 is effectively reduced, and at the same time, the cost of separately manufacturing the light guide plate is reduced, thereby reducing the thickness of the electronic device 2 and the cost of the electronic device 2; the arrangement of the reflecting member 14 improves the light utilization rate and the display effect of the electronic device 2.
