Abstract

A display method, an electronic device, and a non-transitory storage medium are provided. The display method includes following steps. A picture having a first transparency is displayed on a touch screen of the electronic device. A touch operation on the touch screen is detected. A second transparency of the picture is determined according to a position of the touch operation, where the second transparency is higher than the first transparency. The picture having the second transparency and a screen image covered by the picture are simultaneously displayed on the touch screen.

Claims

1. A display method for an electronic device, wherein the electronic device has a touch screen, the display method comprising:

displaying a picture having a first transparency on the touch screen;

detecting a touch operation on the touch screen;

determining a second transparency of the picture according to a position of the touch operation, wherein the second transparency is higher than the first transparency; and

simultaneously displaying the picture having the second transparency and a screen image covered by the picture on the touch screen.

2. The display method according to claim 1, wherein the second transparency and a displacement of the touch operation have a positive correlation.

3. The display method according to claim 1, wherein the step of determining the second transparency of the picture according to the position of the touch operation further comprises:

calculating the second transparency of the picture according to a displacement of the touch operation.

4. The display method according to claim 1, wherein the step of determining the second transparency of the picture according to the position of the touch operation further comprises:

when a displacement of the touch operation is in a predetermined range, setting the second transparency as a predetermined transparency corresponding to the predetermined range.

5. The display method according to claim 1, wherein the step of determining the second transparency of the picture according to the position of the touch operation further comprises:

when the position of the touch operation is in a predetermined area of the touch screen, setting the second transparency as a predetermined transparency corresponding to the predetermined area.

6. The display method according to claim 1 further comprising:

displaying a switch boundary on the touch screen, wherein the step of determining the second transparency of the picture according to the position of the touch operation further comprises;

calculating a minimum distance between the position of the touch operation and the switch boundary; and

determining the second transparency according to the minimum distance, wherein the second transparency and the minimum distance have a negative correlation.

7. The display method according to claim 1 further comprising:

displaying a switch boundary on the touch screen, wherein the step of determining the second transparency of the picture according to the position of the touch operation further comprises;

defining that a start position of the touch operation is corresponding to a first predetermined transparency;

defining that the switch boundary is corresponding to a second predetermined transparency, wherein the second predetermined transparency is higher than the first predetermined transparency;

determining a value according to a linear distance between an end position of the touch operation and the start position and a linear distance between the end position of the touch operation and the switch boundary; and

performing an interpolation operation on the first predetermined transparency, the second predetermined transparency, and the value to obtain the second transparency.

8. The display method according to claim 1 further comprising:

displaying a switch boundary on the touch screen, wherein the touch screen is divided by the switch boundary into a start area and a switch area, wherein the step of determining the second transparency of the picture according to the position of the touch operation further comprises;

when the position of the touch operation is in the start area, defining that a start position of the touch operation is corresponding to a first predetermined transparency and the switch boundary is corresponding to a second predetermined transparency, wherein the second predetermined transparency is higher than the first predetermined transparency, determining a value according to a linear distance between an end position of the touch operation and the start position and a linear distance between the end position of the touch operation and the switch boundary, and performing an interpolation operation on the first predetermined transparency, the second predetermined transparency, and the value to obtain the second transparency; and

when the position of the touch operation is in the switch area, setting the second transparency as a predetermined transparency corresponding to the switch area.

9. The display method according to claim 1 further comprising:

updating the screen image in response to the touch operation detected on the touch screen.

10. The display method according to claim 1, wherein a covering range of the picture is equal to an actual maximum display area of the touch screen.

11. The display method according to claim 1 further comprising:

displaying at least one image on the touch screen, wherein

the touch operation is a touch operation corresponding to one of the at least one image, and the screen image is corresponding to the image.

12. The display method according to claim 11 further comprising:

displaying a switch boundary on the touch screen, wherein the touch screen is divided by the switch boundary into a start area and a switch area, and the image is displayed in the start area on the touch screen;

when the touch operation ends, determining whether an end position of the touch operation is in the switch area on the touch screen; and

when the end position of the touch operation is in the switch area, not displaying the picture on the touch screen.

13. The display method according to claim 12 further comprising:

when the end position of the touch operation is in the switch area, switching the electronic device from a screen locking mode to an unlocking mode.

14. The display method according to claim 12, wherein the step of displaying the switch boundary on the touch screen further comprises:

displaying the switch boundary on the touch screen in response to the touch operation detected on the touch screen.

15. The display method according to claim 14, wherein the switch boundary surrounds an initial display position of the image.

16. The display method according to claim 11, wherein the step of displaying the at least one image on the touch screen comprises:

displaying the at least one image according to at least one notify event.

17. The display method according to claim 1, wherein the screen image is one of a key frame, a short message service (SMS) screen image, an email screen image, a notebook screen image, a calendar or memo screen image, and a graphic screen image.

18. The display method according to claim 1, wherein the step of displaying the picture having the first transparency on the touch screen further comprises:

displaying the picture having the first transparency on the touch screen in response to the touch operation detected on the touch screen.

19. An electronic device, comprising:

a touch screen;

a memory;

at least one processor; and

at least one program, stored in the memory and configured to be executed by the at least one processor, wherein the at least one program comprises instructions for executing following operations;

displaying a picture having a first transparency on the touch screen;

detecting a touch operation on the touch screen;

determining a second transparency of the picture according to a position of the touch operation, wherein the second transparency is higher than the first transparency; and

simultaneously displaying the picture having the second transparency and a screen image covered by the picture on the touch screen.

20. A non-transitory storage medium storing at least one program instruction, and after the at least one program instruction is located into an electronic device having a touch screen, the at least one program instruction executes following steps:

displaying a picture having a first transparency on the touch screen;

detecting a touch operation on the touch screen;

determining a second transparency of the picture according to a position of the touch operation, wherein the second transparency is higher than the first transparency; and

simultaneously displaying the picture having the second transparency and a screen image covered by the picture on the touch screen.
