Abstract

An interface display method and an electronic device are provided. The interface display method comprises steps of: during processing an interface display request of an application program, determining whether the interface display request meets a preset condition or not ( 101 ); if the interface display request meets the preset condition, acquiring at least one fingerprint acquisition area according to the interface display request ( 102 ); displaying an interface according to the interface display request ( 103 ), and activating a fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area ( 104 ); and if the interface display request does not meet the preset condition, displaying the interface according to the interface display request, and controlling the fingerprint recognition sensor of the electronic device to be in an inactive state ( 105 ). The method reduces the power consumption of the electronic device, and prolongs the service life of the electronic device.

Claims (65)

1. An interface display method, comprising:

during processing an interface display request of an application program, determining whether the interface display request meets a preset condition or not;

if the interface display request meets the preset condition, acquiring at least one fingerprint acquisition area according to the interface display request;

displaying an interface according to the interface display request, and activating a fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area; and

if the interface display request does not meet the preset condition, displaying the interface according to the interface display request, and controlling the fingerprint recognition sensor of the electronic device to be in an inactive state,

wherein the preset condition is that the interface display request contains a preset fingerprint identifier;

wherein after displaying the interface according to the interface display request, the method further comprises:

determining whether or not the at least one fingerprint acquisition area can respond to a touch event; and

if the at least one fingerprint acquisition area can respond to a touch event, activating the fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area;

wherein said determining whether or not the at least one fingerprint acquisition area can respond to a touch event specifically comprises:

determining whether or not the at least one fingerprint acquisition area is shielded;

if the at least one fingerprint acquisition area is not shielded, determining whether or not the at least one fingerprint acquisition area is operable; and

if the at least one fingerprint acquisition area is operable, determining that the at least one fingerprint acquisition area can respond to a touch event.

2. The interface display method according to claim 1 , wherein the fingerprint identifier is contained in the interface display request by: adding the fingerprint identifier in a description of an area requiring fingerprint acquisition of the interface display request; and

said acquiring at least one fingerprint acquisition area according to the interface display request specifically comprises:

acquiring the at least one fingerprint acquisition area corresponding to the fingerprint identifier from the display interface request.

3. The interface display method according to claim 1 , wherein the fingerprint acquisition area is a rectangle, and said acquiring at least one fingerprint acquisition area according to the interface display request specifically comprises:

acquiring coordinates of two vertexes on a diagonal line of the at least one fingerprint acquisition area according to the interface display request.

4. The interface display method according to claim 1 , wherein said activating a fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area specifically comprises:

transmitting driving parameters to a driving module; wherein the driving parameters include an activating instruction and information characterizing the at least one fingerprint acquisition area; and

activating the fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area through the driving module.

5. An electronic device, comprising at least one processor, a display screen, a fingerprint recognition sensor, and a memory; the display screen, the fingerprint recognition sensor and the memory are respectively communicatively connected to the at least one processor; wherein a fingerprint recognition area of the fingerprint recognition sensor is located in at least part of a display area of the display screen;

the memory stores instructions executable by the at least one processor to enable the at least one processor to perform:

during processing an interface display request of an application program, determining whether the interface display request meets a preset condition or not;

if the interface display request meets the preset condition, acquiring at least one fingerprint acquisition area according to the interface display request;

displaying an interface according to the interface display request, and activating a fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area; and

wherein the preset condition is that the interface display request contains a preset fingerprint identifier;

wherein the processor is further configured to perform, after displaying the interface according to the interface display request:

determining whether or not the at least one fingerprint acquisition area can respond to a touch event: and

if the at least one fingerprint acquisition area can respond to a touch event, activating the fingerprint recognition sensor corresponding to the at least one fingerprint acquisition area;

wherein the processor is further configured to determine whether or not the at least one fingerprint acquisition area can respond to a touch event specifically by:

determining whether or not the at least one fingerprint acquisition area is shielded;

if the at least one fingerprint acquisition area is not shielded, determining whether or not the at least one fingerprint acquisition area is operable; and

if the at least one fingerprint acquisition area is operable, determining that the at least one fingerprint acquisition area can respond to a touch event.

6. The electronic device according to claim 5 , wherein the fingerprint recognition sensor is an optical fingerprint recognition sensor; and

the optical fingerprint recognition sensor reuses at least part of self-luminous display pixels of the display screen as a light source.
