Abstract

A wearable electronic device and a display switching method thereof, includes turning on a first display apparatus of the wearable electronic device to make the first display apparatus in a working state; rendering a first image in a first display region of the first display apparatus with a first display effect by the first display apparatus; obtaining first parameter information related to an input operation, by a sensing apparatus of the wearable electronic device; judging whether a second display apparatus of the wearable electronic device is to be turned on or not, according to the sensing parameter; and rendering a second image in a second display region of the second display apparatus with a second display effect by the second display apparatus, when the second display apparatus is to be turned on to make the second display apparatus in the working state.

First claim

The invention claimed is:

1. A display switching method for a wearable electronic device, the method comprising:
turning on a first display apparatus of the wearable electronic device to make the first display apparatus in a working state;
rendering a first image in a first display region of the first display apparatus with a first display effect by the first display apparatus;
obtaining a sensing parameter related to an input operation by a sensing apparatus of the wearable electronic device;
judging whether a second display apparatus of the wearable electronic device is to be turned on or not and obtaining a first judging result according to the sensing parameter; and
rendering a second image in a second display region of the second display apparatus with a second display effect by the second display apparatus, when the first judging result indicates that the second display apparatus is to be turned on to make the second display apparatus in the working state,
a size of the first image rendered in the first display region with the first display effect which is viewed by a user is larger than a size of the second image rendered in the second display region with the second display effect which is perceived by the user, when a distance from the user to a frame of the wearable electronic device is a first distance;
wherein a size of the first image rendered in the first display region with the first display effect which is viewed by the user is equal to a size of the first display region, when a distance from the user to a frame of the wearable electronic device is a second distance; and
the step of rendering a second image in the second display region with a second display effect by the second display apparatus comprises:
controlling a display output of the second display apparatus at a first timing, so that the size of the second image rendered in the second display region with the second display effect which is perceived by the user is equal to the size of the first display region, when the distance from the user to the frame is the second distance; and
controlling the display output of the second display apparatus at a second timing after the first timing, so that the size of a third image rendered in the second display region with the second display effect which is perceived by the user is larger than the size of the first display region, when the distance from the user to the frame is the second distance;
and wherein display content of the second image is consistent with that of the first image.

2. The method of claim 1 , wherein the first display apparatus and the second display apparatus are different display apparatuses, and the first display region and the second display region are different display regions.

3. The method of claim 2 , wherein the first display apparatus and the second display apparatus are display apparatuses following different display principles, and a size of the first display region is larger than a size of the second display region.

4. The method of claim 2 , wherein the first display apparatus comprises a first display screen having a first size equal to a size of the first display region;
the second display apparatus comprises a second display screen having a second size smaller than a size of the second display region;
a size of the first image rendered in the first display region with the first display effect that is viewed by a user is equal to the size of the first display region, when a distance from the user to a frame of the wearable electronic device is a second distance; and
a size of the second image rendered in the second display region with the second display effect which is perceived by the user is larger than the size of the second display region, when a distance from the user to the frame is the second distance.

5. The method of claim 1 , wherein the sensing apparatus is a first sensing apparatus for obtaining spatial location information of the electronic device under a control of an input operation by a user; and
the step of judging whether the second display apparatus is to be turned on or not according to the sensing parameter comprises judging whether the electronic device is moved from a first location to a second location in a gravity direction or not, and judging whether the electronic device is rotated from a first angle to a second angle around a first operating body of the user as a center, according to the spatial location information.

6. The method of claim 1 , wherein the sensing apparatus is a second sensing apparatus for sensing control operation information generated when a second operating body of a user is approaching or contacting a sensing region comprising at least a part of the first display region and at least a part of the second display region; and
the step of judging whether the second display apparatus is to be turned on or not according to the sensing parameter comprises judging whether the second operating body slides from the at least a part of the first display region to the at least a part of the second display region or not, according to the control operation information.

7. The method of claim 1 , wherein a size of the first image rendered in the first display region with the first display effect that is viewed by a user is equal to a size of the first display region, when a distance from the user to a frame of the wearable electronic device is a second distance; and
the step of rendering a second image in the second display region with a second display effect by the second display apparatus comprises:
controlling a display output of the second display apparatus at a first timing, so that a size of the second image rendered in the second display region with the second display effect that is perceived by the user is equal to the size of the first display region, when the distance from the user to the frame is the second distance; and
controlling the display output of the second display apparatus at a second timing after the first timing, so that a size of a third image rendered in the second display region with the second display effect that is perceived by the user is larger than the size of the first display region, when the distance from the user to the frame is the second distance;
and wherein display content of the second image is consistent with that of the first image.

8. The method of claim 1 , wherein the step of rendering a second image in the second display region with a second display effect by the second display apparatus comprises:
controlling a display output of the first display apparatus at a first timing, so that a size of the first image rendered in the first display region with the first display effect that is viewed by a user is equal to the size of the first display region, when a distance from the user to a frame of the wearable electronic device is the second distance; and
controlling the display output of the first display apparatus at a second timing after the first timing, so that the size of the first image rendered in the first display region with the first display effect that is viewed by the user is smaller than the size of the first display region, when the distance from the user to the frame is the second distance;
controlling the display output of the second display apparatus at a third timing after the second timing, so that a size of the second image rendered in the second display region with the second display effect that is perceived by the user is smaller than the size of the first display region, when the distance from the user to the frame is the second distance; and
controlling the display output of the second display apparatus at a fourth timing after the third timing, so that a size of a third image rendered in the s
