Abstract

An electronic device and a display method includes a main body apparatus with a processing unit which generates a first image and performs display control; a first fixing apparatus connected with the main body apparatus, which maintains a relative location relationship between the electronic device and at least a part of body of a user when the user wears the electronic device; and a first display unit arranged on the main body apparatus and/or the first fixing apparatus, which outputs the first image; wherein the first display unit comprises a first display component which displays the first image, and a first optical component which receives light corresponding to the first image emitted from the first display component, and changes the light path of the light corresponding to the first image to form a magnified virtual image corresponding to the first image.

Claims

1. An electronic device, comprising:

a main body apparatus comprising a processing unit which generates a first image and performs display control;

a first fixing apparatus connected with the main body apparatus, which maintains a relative location relationship between the electronic device and at least a part of body of a user when the user wears the electronic device;

a first display unit arranged on the main body apparatus and/or the first fixing apparatus, which outputs the first image; and

a sensor unit arranged on the main body apparatus or the first fixing apparatus, which generates a first control signal when sensing that a first predetermined condition is met, the processing unit controlling an on/off of the first display unit according to the first control signal;

wherein the first display unit comprises a first display component which displays the first image, and a first optical component which receives light corresponding to the first image emitted from the first display component, and changes the light path of the light corresponding to the first image to form a magnified virtual image corresponding to the first image.

2. The electronic device according to claim 1, wherein the first fixing apparatus has at least a first fixed state in which the first fixing apparatus can be at least a part of an annular space or an approximate annular space meeting a first predetermined condition, the annular space or the approximate annular space being capable of surrounding an outer side of a cylinder meeting a second predetermined condition.

3. The electronic device according to claim 2, wherein at least a part of the first optical component is a component the transmittance of which meets a predetermined condition in an outward direction of the annular space or the approximate annular space.

4. The electronic device according to claim 3, wherein the transmittance of the electronic device meets the predetermined condition in the outward direction of the annular space or the approximate annular space corresponding to at least a part of the first optical component.

5. The electronic device according to claim 2, further comprising a second display unit the type of which is different from that of the first display unit, wherein one of the first display unit and the second display unit is arranged on the main body apparatus, the other of which is arranged on the first fixing apparatus, and the display direction of the second display unit is the outward direction of the annular space or the approximate annular space.

6. The electronic device according to claim 5, wherein the first display unit is arranged on the main body apparatus, and the second display unit is arranged on the first fixing apparatus;

or the second display unit is arranged on the main body apparatus and the first display unit is arranged on the first fixing apparatus.

7. The electronic device according to claim 5, further comprising a third display unit arranged on the main body apparatus or the first fixing apparatus together with the first display unit, which outputs a third image, wherein the third display unit comprises a second display component configured to display the third image, and a second optical component configured to receive light corresponding to the third image emitted from the second display component and changing the light path of the light corresponding to the third image to form a magnified virtual image corresponding to the third image.

8. The electronic device according to claim 2, further comprising an image capturing unit arranged on the main body apparatus or the first fixing apparatus, and an image capturing direction of the image capturing unit is opposite to an image output direction of the first display unit in a radial direction of the annular space or the approximate annular space.

9. The electronic device according to claim 8, wherein the image capturing unit captures an interaction action of the user to generate a first image capturing signal, the processing unit converts the first image capturing signal into a second control signal to control the display of a second image.

10. The electronic device according to claim 8, wherein the image capturing unit captures a first sub image in the image capturing direction, and the processing unit generates a second sub image and superimposes the first sub image with the second sub image to generate the first image.

11. The electronic device according to claim 2, wherein diameter of the annular space or the approximate annular space is variable, and the difference between the maximum and the minimum of the diameter is larger than a predetermined threshold.

12. The electronic device according to claim 11, wherein the first fixing apparatus comprises at least a flexible unit having a relaxed first state in which the diameter of the annular space or the approximate annular space is the maximum, and a tight second state in which the diameter of the annular space or the approximate annular space is the minimum.

13. The electronic device according to claim 11, wherein the first fixing apparatus further comprises an adjusting unit which controls the diameter of the annular space or the approximate annular space to change between the maximum and the minimum.

14. The electronic device according to claim 2, wherein the main body apparatus comprises a first connecting unit, the first fixing apparatus comprises a second connecting unit, and the main body apparatus and the first fixing apparatus are connected with each other through the coupling between the first connecting unit and the second connecting unit;

the electronic device further comprises a second fixing apparatus having at least a second fixed state in which the second fixing apparatus is at least a part of an approximate rectangular space capable of surrounding an outer surface of an object meeting a third predetermined condition, the first fixing apparatus comprises a third connecting unit, and the electronic device is switched from the first fixed state to the second fixed state when the first connecting unit and the second connecting unit are discoupled and the first connecting unit and the third connecting unit are coupled.

15. The electronic device according to claim 1, wherein the sensor unit is an acceleration sensor, the acceleration component value in the gravity direction of the first control signal is larger than or equal to a predetermined value, and the processing unit controls the on/off of the first display unit according to the first control signal.

16. The electronic device according to claim 1, wherein the main body apparatus comprises at least one first sub unit, the first fixing apparatus comprises at least one second sub unit, and the at least one first sub unit and the at least one second sub unit form a data or electrical connection.

17. The electronic device according to claim 16, wherein the at least one second sub unit is connected to the first fixing apparatus through a dismountable connection interface.

18. The electronic device according to claim 16, wherein one or more of the at least one first sub unit and one or more of the at least one second sub unit are sub units with the same type and different performance parameters.
