Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
With the updating of electronic devices such as smart phones, tablet computers, wearable devices and the like, the electronic devices mostly adopt underscreen fingerprint identification. At present, the consumption terminal has more and more strong demand for identifying the fingerprint under the screen of the electronic device, the development of the fingerprint under the screen is promoted, and the fingerprint under the screen is mainly applied to the OLED screen at present. The OLED screen is a self-luminous screen, and a sensor is arranged on the back of the screen by utilizing the self-luminous characteristic of materials, so that the collection and identification of fingerprint images are realized.
In order to collect the fingerprint of the user better, the fingerprint identification is more sensitive, the problem that the fingerprint identification is difficult to identify or the identification is easy to make mistakes is avoided, the fingerprint identification is collected under the screen, and the display screen can additionally perform light supplement in the area where the user presses the fingerprint. Through a period of time's use, the regional luminescent material live time that is used for making fingerprint identification's regional correspondence in the display screen increases than other regions, and ageing is serious, and the luminance of highlight facula can take place the decay, because weakening of light intensity can influence the reduction of the hardware module received signal volume that fingerprint identification corresponds, reduces the fingerprint identification quality, and then influences user and uses experience. The solution provided by the present application enables to improve the problems set out above. The following is further illustrated with reference to examples.
Referring to fig. 1, a schematic flowchart of an embodiment of a method for controlling display of a display screen provided in the present application is shown, where the method includes: step 101 and step 102, wherein:
step 101: in the process of collecting fingerprints, the preset area forms a light spot area at the part for collecting the fingerprints, and controls part of pixels in the light spot area to be in a preset working state, wherein the preset working state is a non-working state or a state with reduced working current, and the resolution of the light spot area is reduced.
The basic framework of the pixels corresponding to the display area in the display screen comprises green pixels, blue pixels and red pixels, namely RGB is uniformly distributed. Fingerprint identification generally adopts white facula or green facula to gather and discern user's fingerprint. The luminescent material of the green, blue and red pixels all need to work when using the white light spot for collecting and identifying the fingerprint of a user. If the green light spot is used for collecting and identifying the fingerprint of the user, only the luminescent material of the green pixel needs to work.
It can be understood that, as described above, a light spot region is formed at a portion of the display screen where the user fingerprint is collected, that is, a part of pixels in the region need to increase current and increase brightness of light when the user fingerprint is collected, so as to collect a clearer fingerprint. In step 101, understandably, the portion of the collected fingerprint is covered by a finger, and high resolution is not needed, so that the method controls part of pixels in the speckle region to be in a preset working state in the process of collecting the fingerprint, and the preset working state is a state of no work or the working current is reduced compared with the current used in displaying. By adopting the method, part of the pixels can rest, and the condition that the fingerprint is in a high-brightness state every time is avoided, so that the service life of the pixels is prolonged.
It is to be understood that, optionally, in an embodiment, the preset area is a fixed local area in the display area of the display screen, that is, the location where the fingerprint of the user is captured is a fixed location. Further, optionally, the preset area may be any position in the display screen. In an embodiment, specifically, the display screen includes a center line passing through the center point, the predetermined area is close to the edge of the display screen, and an orthographic projection of the predetermined area coincides with the center line. For example, the preset area may be the left side or the right side of the lower half edge of the display screen, or other positions of the display screen, which is not limited herein.
Optionally, in another embodiment, the preset area is the entire display area of the display screen, and any position of the display area may form a light spot area when the fingerprint is acquired. And then the pixels in different areas take a rest in turn, the service life of the pixels is further prolonged, and the condition that local display is affected is improved.
It is to be understood that the light formed by the spot area is formed by the green pixel, the blue pixel and the red pixel or the light formed by the spot area is formed by only the green pixel.
Further, as shown in fig. 2, the light formed by the light spot region is formed by operating a green pixel, a blue pixel and a red pixel, and includes a first pixel 110 and a second pixel 120, where the first pixel 110 is a pixel in a preset operating state, and the second pixel 120 is a pixel for increasing current to supplement light so as to better collect a user fingerprint. The first pixel 110 and the second pixel 120 each include a green pixel 112, a blue pixel 114, and a red pixel 116, each color of the green pixel 112, the blue pixel 114, and the red pixel 116 forms a column, the pixel types of adjacent columns are different, for example, the red pixel, the green pixel, and the blue pixel are respectively arranged from left to right, and the pixels in the preset working state are arranged at intervals, that is, the pixels in the preset working state in the pixels in the adjacent columns are distributed in a staggered manner.
In another embodiment, as shown in fig. 3, the light formed by the light spot region is formed by only green pixels, and includes a third pixel 30 and a fourth pixel 40, where the third pixel 30 is a pixel in a preset operating state, and the fourth pixel 40 is a pixel for increasing current to supplement light so as to better collect the user fingerprint. The third pixels 30 and the fourth pixels 40 are spaced apart. It is understood that the portions not filled in fig. 3 are blue pixels and red pixels.
Step 102: and controlling different pixels in the preset area to be in a preset working state in turn at different time periods.
Specifically, it can be understood that the fingerprint collection frequency of the display screen in the electronic device is very high, for example, unlocking, such as payment, etc., so if only a fixed portion of pixels are in the preset working state, and other another portion of pixels are not controlled, the pixels that are not in the preset working state need to increase the passing current each time the user fingerprint is collected, and thus attenuation is easily formed. In step 102, different pixels in the preset area are controlled to be in a preset working state in turn at different time periods, so that the pixels in the spot area forming the light spot have a rest in turn.
For example, when the light formed by the light spot region is formed by operating green, blue and red pixels, the pixels in the preset operating state may be controlled to alternately switch between fig. 2 and 4. When the light formed by the spot area is formed by only the green pixels, the pixels in the preset operation state can be controlled to alternately switch between fig. 3 and fig. 5. And furthermore, when the user fingerprint is collected at each time, the pixels in the light spot area are not required to be completely used or are completely used, but the working current of part of the pixels is reduced, and the pixels are used alternately to emit light, so that the service life of the luminescent material in the light spot area can be prolonged, even the time is prolonged by one time or more, and the influence on the performance caused by the aging of the pixel luminescent material is reduced.
Referring to fig. 6, a schematic flowchart of another embodiment of a method for testing antenna performance of an electronic device according to the present application is shown. It can be understood that, when the preset area is the entire display area of the display screen, and any position of the display area can form a light spot area during fingerprint collection, it is necessary to detect where the user presses on the display screen before controlling a part of pixels to be in the preset working state, the method includes steps 201 to 203, where step 202 and step 203 are consistent with steps 101 and 102 in the previous embodiment, which is not described herein again specifically:
step 201: and detecting whether the fingerprint is being acquired, and if so, determining the light spot area.
It can be understood that when the user's finger touches the display screen, the capacitance of the touched local area changes. On the other hand, the user presses the fingerprint for a period of time when the user slides the screen, clicks the screen, or the typing action stays on the screen for a period of time significantly longer than the case of fingerprint unlocking or fingerprint payment. Therefore, according to the two aspects, whether the fingerprint is acquired or not can be detected, and if so, the facula area is determined.
Step 202: and controlling part of pixels in the speckle region to be in a preset working state.
Step 203: and controlling different pixels in the preset area to be in a preset working state in turn at different time periods.

the first control module 10 is configured to form a light spot region at a portion where a fingerprint is collected in a preset region in a fingerprint collecting process, and control a part of pixels in the light spot region to be in a preset working state, where the preset working state is an inoperative state or a state where a working current is reduced, and a resolution of the light spot region is reduced.
