Electronic paper display device

Abstract

This invention provides an electronic paper display device, including a display module and an operation module. The display module has a display interface and a bottom surface. One edge of the bottom surface has a first connecting portion, and the bottom surface also has a support groove. The operation module has a second connecting portion corresponding to the first connecting portion. The operation module is connected to the first connecting portion of the display module through the second connecting portion, forming a first combination configuration. The operation module is detached from the first connecting portion, with one end of the operation module housed and engaged in the support groove of the display module, and the other end of the operation module extending and abutting against an external plane, forming a second combination configuration. Therefore, this invention allows the operation module to be positioned in different locations on the display module to form various different combination configurations, meeting the user's operational needs in different situations.

Claims

1. An electronic paper display device, comprising: A display module has a display interface and a bottom surface opposite to the display interface, the bottom surface having a first connecting portion and a bracket groove; and an operation module having a second connecting portion corresponding to the first connecting portion; wherein the second connecting portion of the operation module is combined with the first connecting portion of the display module to form a first combination configuration; the operation module is separated from the first connecting portion, and one end of the operation module is accommodated and engaged in the bracket groove of the display module, and the other end of the operation module extends and abuts against an external plane to form a second combination configuration.

2. The electronic paper display device as described in claim 1, wherein, The operating module houses an extended battery and a logic control unit, which provide power compensation and data transmission for the display module in the first combined configuration.

3. The electronic paper display device as described in claim 2, wherein, The operation module also includes an operation control interface, which is disposed on the surface of the operation module and electrically connected to the logic control unit.

4. The electronic paper display device as described in claim 1, wherein, The bottom surface of the display module is a flat surface, and the thickness of the display module is between 4 mm and 6 mm.

5. The electronic paper display device as described in claim 1, wherein, In this second configuration, the bracket groove has an inclined angle to limit the engagement angle of the operating module.

6. The electronic paper display device as described in claim 5, wherein, In this second configuration, the display module stands upright on the external plane at an angle between 45 and 75 degrees.

7. The electronic paper display device as described in claim 1 further includes a sensing module disposed within the display module.

8. The electronic paper display device as described in claim 7, wherein, The sensing module is a magnetic field sensor located near the bracket recess, used to detect changes in the magnetic field when the operating module enters the second combination mode.

9. The electronic paper display device as described in claim 7, wherein, The sensing module is a triaxial sensor used to detect the tilt attitude of the display module in space.

10. The electronic paper display device as described in claim 1, wherein, The first and second joints include mutually cooperating magnetic units, providing an adsorption force and a lateral anti-slip force between the first and second joints.

11. The electronic paper display device as described in claim 1, wherein, The first and second joints also include mutually cooperating transmission interfaces.
