Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The image display method provided by the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 may include a display device, where the terminal 102 may display a screen-extinguishing image on the display device, where the terminal 102 may obtain the screen-extinguishing image from the server 104 through a network, or may generate the screen-extinguishing image locally on the terminal 102, where the terminal 102 may display a current screen-extinguishing image frame corresponding to the screen-extinguishing image when the display device is in the screen-extinguishing display mode, and if the current screen-extinguishing image frame is not the last frame in all the screen-extinguishing image frames, the terminal 102 may determine a plurality of second outwards-diffused light-emitting pixels corresponding to the next screen-extinguishing image frame according to a plurality of first light-emitting pixels in the current screen-extinguishing image frame, and control the plurality of second light-emitting pixels to emit light, and other pixels do not emit light, so as to switch the current screen-extinguishing image frame in the display device to the next screen-extinguishing image frame. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, an image display method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step S202, displaying a current screen-extinguishing image frame corresponding to a screen-extinguishing image when the display device is in a screen-extinguishing display mode; the screen-off image corresponds to at least two screen-off image frames.
The display device may be a device disposed in the terminal 102 for displaying, and the terminal 102 may include a screen-off display mode, for example, the screen-off display mode may be entered after the terminal 102 is idle or locked for a period of time, in which the terminal 102 may display a specific screen-off image, which may be generated or acquired locally, or may be generated or acquired from the server 104. The off-screen image displayed by the terminal 102 in the off-screen display mode may include at least two off-screen image frames, and each of the off-screen image frames may be a different display effect. Specifically, the at least two screen-off image frames may be four screen-off image frames including a start frame, a second frame, a third frame, and a last frame. It should be noted that the at least two screen-extinguishing image frames may be not limited to four frames, but may be more than four image frames or less than four image frames. Each frame may display a different image in the display device, respectively. When entering the first-time screen-off display mode, the terminal 102 may first display a start frame, and may also display other screen-off image frames corresponding to the start frame.
Step S204, if the current screen-extinguishing image frame does not belong to the last frame of at least two screen-extinguishing image frames, determining a plurality of second light-emitting pixel points corresponding to the next screen-extinguishing image frame according to the plurality of first light-emitting pixel points in the current screen-extinguishing image frame; the plurality of second light-emitting pixel points are outwards diffused and distributed relative to the plurality of first pixel points.
The screen-off image frames may include at least two screen-off image frames, and may include a start frame, a second frame, a third frame, and a last frame, for example. Note that the screen-off image frame may be other number of image frames than four. The terminal 102 may detect a current screen-extinguishing image frame of the display device and determine, specifically, the terminal 102 may determine whether the current screen-extinguishing image frame is a last frame of the at least two screen-extinguishing image frames, if not, the terminal 102 may determine a plurality of second light-emitting pixels corresponding to a next screen-extinguishing image frame according to a plurality of first light-emitting pixels in the current screen-extinguishing image frame, for example, the terminal 102 may search, based on a plurality of first light-emitting pixels in the current screen-extinguishing image frame, a pixel position of a light-emitting pixel in the display device that may be used as the next screen-extinguishing image frame, thereby implementing a conversion effect from the current screen-extinguishing image frame to the next screen-extinguishing image frame. The outward diffusion distribution of the plurality of second light emitting pixel points relative to the plurality of first pixel points may be, for example, an effect of gradually diffusing the image frames of the frame-by-frame screen-extinguishing image, and the diffusion amplitude may be larger and larger. Specifically, the terminal 102 may select a corresponding second light emitting pixel point in a specific area around each first light emitting pixel point, and the terminal 102 may also use different transformation modes according to the positions of the current screen-extinguishing image frame in all the screen-extinguishing image frames.
In addition, if the screen-extinguishing image frame corresponding to the screen-extinguishing image includes four frames, such as the start frame, the second frame, the third frame and the last frame, the start frame, the second frame, the third frame and the last frame may be four frames that are sequentially carousel. The starting frame may be a line image frame, and in order to achieve gradual diffusion of the light emitting pixels in each of the screen-extinguishing image frames, the light emitting pixels in each of the screen-extinguishing image frames may be at least a preset number of pixels apart. For example, the light emitting pixels of the second frame are spaced apart from each other by at least a first number of pixels; the light emitting pixels of the third frame are spaced apart from each other by at least a second number of pixels; the last frame of luminous pixel points are at least separated from each other by a third number of pixel points; and, the number of the first number of pixels, the second number of pixels, and the third number of pixels may be sequentially increased. Specifically, the terminal 102 may set 3 pixels around the light-emitting pixel point a' of the second frame to be transparent, that is, not emit light, and form a distance D2 at least 3 pixels apart, that is, the first number of pixel points; the terminal 102 may be configured to not emit light around 10 pixels around the light-emitting pixel point a″ of the third frame, and form a distance D2' spaced by at least 10 pixels, that is, the second number of pixels; the terminal 102 may be set to not emit light at 20 pixels from the light emitting pixel point a' "of the last frame, forming a distance D2" of at least 20 pixels apart, i.e., the third number of pixels described above. Therefore, the corresponding distances of D2, D2' and D2″ can be gradually increased, so as to realize the effect that the screen-extinguishing image is diffused frame by frame and the light-emitting pixels are continuously reduced.
Step S206, the second light emitting pixels are controlled to emit light, and the other pixels do not emit light, so as to switch the current screen-extinguishing image frame of the display device to the next screen-extinguishing image frame.
The second light-emitting pixel points can be light-emitting pixel points in the next screen-extinguishing image frame, each second light-emitting pixel point can be determined according to the first light-emitting pixel point in the current screen-extinguishing image frame, and the first light-emitting pixel point can be light-emitting pixel point in the current screen-extinguishing image frame. After determining each second light emitting pixel point in the next screen-extinguishing image frame, the terminal 102 may control the plurality of second light emitting pixel points to emit light, and make other pixel points not emit light, so as to realize switching from the current screen-extinguishing image frame to the next screen-extinguishing image frame.
In the image display method, the current screen-extinguishing image frame corresponding to at least two screen-extinguishing images is displayed when the display device is in the screen-extinguishing display mode, if the current screen-extinguishing image frame does not belong to the last frame of the at least two screen-extinguishing image frames, a plurality of second light-emitting pixel points which are distributed outwards and correspond to the next screen-extinguishing image frame are determined according to a plurality of first light-emitting pixel points in the current screen-extinguishing image frame, the plurality of second light-emitting pixel points are controlled to emit light, and other pixel points do not emit light, so that the current screen-extinguishing image frame of the display device is switched to the next screen-extinguishing image frame. Compared with the traditional mode of displaying the screen-extinguishing image by moving the whole display block, the screen-extinguishing image diffusion display method and device achieve the effect of effectively slowing down the aging of the screen pixel points by controlling all the pixel points of the display device in the screen-extinguishing display mode.
In one embodiment, determining a plurality of second light emitting pixels corresponding to a next screen-extinguishing image frame according to the plurality of first light emitting pixels in the current screen-extinguishing image frame includes: selecting a plurality of spaced luminous pixel points from the luminous pixel points of the current screen-extinguishing image frame to serve as a plurality of first luminous pixel points; for each first light-emitting pixel point, acquiring a non-light-emitting pixel point which is at least spaced by a set distance from the first light-emitting pixel point, and taking the non-light-emitting pixel point as a second light-emitting pixel point corresponding to the first light-emitting pixel point; and obtaining a plurality of second light-emitting pixel points according to the second light-emitting pixel points corresponding to the first light-emitting pixel points.
In this embodiment, the terminal 102 may determine a plurality of second light emitting pixels corresponding to the next screen-extinguishing image frame according to a plurality of first light emitting pixels in the current screen-extinguishing image. The screen-extinguishing image frames may include at least two screen-extinguishing image frames, for example, four frames including a start frame and a non-start frame. The terminal 102 may select a plurality of spaced pixels from the pixels of the current screen-off image frame as a plurality of first pixels, and the terminal 102 may determine a different selection range for whether the current screen-off image frame is a start frame or a non-start frame. Specifically, if the initial frame is a line image, the terminal 102 may select a pixel point at a line edge of the line image as the first light emitting pixel point, and may continue to select the remaining line edge pixel points after the processing of the pixel point at the line edge selected at this time is completed, so as to know that all the light emitting pixel points in the line image are processed to form a non-line image. If the frame is a non-initial frame, the non-initial frame may be a non-line image, and the terminal 102 may select a part of the light emitting pixels from the current screen-extinguishing image frame as a plurality of first light emitting pixels, specifically, the terminal 102 may randomly select one of every n light emitting pixels in the screen-extinguishing image frame of the non-initial frame to be non-light emitting, for example, when the screen-extinguishing image frame is four frames, n of each frame may be gradually enlarged, specifically, the terminal 102 may randomly select one of every 20 light emitting pixels in the second frame to be non-light emitting, randomly select one of every 10 light emitting pixels in the third frame to be non-light emitting, and randomly select one of every 3 light emitting pixels in the last frame to be non-light emitting. So that the remaining light emitting pixels in each frame can be used as the plurality of first light emitting pixels.
The terminal 102 may acquire, for each first light emitting pixel, a non-light emitting pixel separated from the first light emitting pixel by at least a set distance after acquiring a plurality of first light emitting pixels of the current screen-extinguishing image frame, as a second light emitting pixel corresponding to the first light emitting pixel. The terminal 102 may determine different setting distances according to whether the current screen-off image frame is a start frame or a non-start frame. The terminal 102 may acquire the non-emitting pixels from different areas and different distances according to the current screen-extinguishing image frames. The terminal 102 may obtain the corresponding second light emitting pixel point for each first light emitting pixel point in the above manner, so that the terminal 102 may obtain a plurality of second light emitting pixel points according to the second light emitting pixel points corresponding to the plurality of first light emitting pixel points.
Through the embodiment, the terminal 102 may select a plurality of first light emitting pixels from the current screen-extinguishing image frame, and obtain the second light emitting pixels corresponding to each first light emitting pixel based on the set interval distance, so as to determine the light emitting pixels of the next screen-extinguishing image frame, realize dynamic screen-extinguishing image, and effectively slow down aging of the screen pixels.
In one embodiment, if the current screen-extinguishing image frame is a start frame, for each first light-emitting pixel, acquiring a non-light-emitting pixel at least spaced by a set distance from the first light-emitting pixel as a second light-emitting pixel corresponding to the first light-emitting pixel, including: acquiring carousel sequences of the next screen-off image frames in at least two screen-off image frames; acquiring a first distance corresponding to the carousel sequencing; for each first luminous pixel point, acquiring an adjacent first luminous pixel point which is closest to the first luminous pixel point, and acquiring a target direction which is perpendicular to the connecting line direction of the first luminous pixel point and the adjacent first luminous pixel point; and acquiring at least one non-light-emitting pixel point which is positioned in the target direction and is within a first distance from the first light-emitting pixel point as a second light-emitting pixel point.
In this embodiment, the screen-extinguishing image frame may include a plurality of frames including a start frame and a non-start frame, and the terminal 102 may determine the second light-emitting pixel point in a specific manner when the current screen-extinguishing image frame is the start frame. The multi-frame screen-extinguishing image frames may be sequentially carousel frames, and the terminal 102 may acquire a carousel order of a next screen-extinguishing image frame in at least two screen-extinguishing image frames, and acquire a first distance corresponding to the carousel order, where the first distance may be set according to an actual situation and may be represented by the number of pixel points. The terminal 102 may obtain, for each first light emitting pixel, an adjacent first light emitting pixel closest to the first light emitting pixel, and obtain a target direction perpendicular to the first light emitting pixel and a connecting line direction of the adjacent first light emitting pixel, and the terminal 102 may obtain, as the second light emitting pixel corresponding to the first light emitting pixel, at least one non-light emitting pixel located in the target direction and within a first distance from the first light emitting pixel. Specifically, as shown in fig. 3, fig. 3 is an interface schematic of a start frame in one embodiment. As shown in fig. 4, fig. 4 is an interface schematic of a second frame in one embodiment. When the current frame is the initial frame, since the initial frame is a line image, the terminal 102 can obtain the connection directions X1 and X2 of the light emitting pixel point A, C at the edge of the line and the nearest adjacent light emitting pixel point B, D; the scattering directions Y1 and Y2 perpendicular to the connecting line direction and the scattering directions Y3 and Y4 perpendicular to the connecting line direction are obtained; the terminal 102 may be spaced at least a first distance D1 from the original pixel in the scattering direction Y1, Y2, the random nonce may select pixels of the next frame, such as a 'C' in fig. 4, the terminal 102 may randomly nonce the colored pixel a 'of the next frame within 5 pixels D1 other than the pixel a of the starting frame, and the randomly selected a' may be 3 pixels from the original first pixel a.
The terminal 102 may select one of the n pixels to emit no light, so as to obtain a diffusion effect, so as to obtain a second pixel in the next screen image frame.
Through the embodiment, when the current screen-extinguishing image frame is the initial frame, the terminal 102 can determine the selection position of the second light-emitting pixel point corresponding to each first light-emitting pixel point through the connection of the plurality of first light-emitting pixel points, thereby realizing the dynamic display of the screen-extinguishing image and effectively slowing down the aging of the screen pixel points.
In one embodiment, if the current screen-extinguishing image frame is a non-initial frame, for each first light-emitting pixel, acquiring a non-light-emitting pixel separated from the first light-emitting pixel by at least a set distance as a second light-emitting pixel corresponding to the first light-emitting pixel, including: acquiring carousel sequences of the next screen-off image frames in at least two screen-off image frames; acquiring a second distance corresponding to the carousel sequence and setting the number of pixel points; and aiming at each first luminous pixel point, acquiring at least one non-luminous pixel point which is at least set in number with the first luminous pixel point at intervals within a second distance, and obtaining a second luminous pixel point corresponding to the first luminous pixel point.
In this embodiment, the multi-frame screen-extinguishing image frame may further include a non-start frame, and if the screen-extinguishing image frame is four frames, the non-start frame may include a second frame, a third frame, and a last frame. The terminal 102 may determine the second light emitting pixel point in a specific manner when the current off-screen image frame is a non-start frame. The terminal 102 may acquire the carousel sequence of the next screen-extinguishing image frame in at least two screen-extinguishing image frames, and acquire a second distance corresponding to the carousel sequence and set number of pixels, where the second distance may be set according to the actual situation and may be represented by the number of pixels. The terminal 102 may obtain, for each first light emitting pixel, at least one non-light emitting pixel that is at least a set number of pixels apart from the first light emitting pixel within a second distance, so as to obtain a second light emitting pixel corresponding to the first light emitting pixel. Specifically, as shown in fig. 5, fig. 5 is an interface schematic of a third frame in one embodiment. As shown in fig. 6, fig. 6 is an interface diagram of the last frame in one embodiment. The non-start frames may include a second frame, a third frame, and a last frame, the second distance and the number of set pixels may increase as the ordering of the rest image frames increases, for example, the second distance and the set pixels of the second frame may be smaller than the third frame, the second distance and the set pixels of the third frame may be smaller than the last frame. For the third frame, the terminal 102 may select the light emitting pixel point a″ of the next frame among 10 pixel points D1 'other than the light emitting pixel point a' of the second frame, and the randomly selected a″ is randomly selected between 3 to 10 pixel points, for example, 5 or 8 pixel points D1 'from the second frame a'. Wherein, the distance D1 of the second frame is smaller than the distance D1 of the third frame, and the distance D1 of the third frame is smaller than the distance D1 of the fourth frame. As shown in fig. 5, the terminal 102 may also set each of the light-emitting pixels to emit no light at other pixels within the D2 distance in a non-start frame. After determining the second plurality of light emitting pixels of the last frame, the terminal 102 may switch the screen-off image from the third frame to the last frame, and the interface schematic diagram of the last frame may be as shown in fig. 6.
It should be noted that, at the pixel point where the current screen-off image frame emits light, the next screen-off image frame does not necessarily emit light, for example, in the second frame as shown in fig. 4, the line area of the original starting frame appears blank. Or as in the third frame of fig. 5, the original image line area is non-luminous, and the outward diffusion effect is formed.
Through the embodiment, when the current screen-extinguishing image frame is a non-initial frame, the terminal 102 can determine each second light-emitting pixel point in the next screen-extinguishing image frame by using the second distance and the set number of pixel points, thereby realizing dynamic display of the screen-extinguishing image and effectively slowing down aging of the screen pixel points.
In one embodiment, further comprising: if the current screen-extinguishing image frame belongs to the last frame, acquiring a starting frame in at least two screen-extinguishing image frames; and switching the current screen-extinguishing image frame of the display equipment into a starting frame according to a preset time interval.
In this embodiment, the screen-extinguishing image frames may include multiple frames, the terminal 102 may sequentially broadcast each screen-extinguishing image frame in turn, and when the terminal 102 detects that the current screen-extinguishing image frame belongs to the last frame, the terminal 102 may obtain a start frame of the at least two screen-extinguishing image frames, and switch the current screen-extinguishing image frame of the display device in the terminal 102 to the start frame according to a preset time interval, thereby implementing the broadcasting of the screen-extinguishing image frames in turn. Specifically, the at least two screen-extinguishing image frames may include four frames, specifically including a start frame, a second frame, a third frame, and a last frame; when the terminal 102 displays the screen, the starting frame to the last frame can be displayed in a carousel mode at a time interval t 1; or the start frame displays the t2 time, then the second to last frames each display the t3 time, and t2 time > t3 time.
Through the embodiment, the terminal 102 may perform carousel on the screen-extinguishing image frames of the multiple frames, so as to dynamically display the screen-extinguishing image, and effectively slow down the aging of the screen pixels.
In one embodiment, further comprising: responding to a moving signal aiming at the display equipment, acquiring a current screen-extinguishing image frame and other screen-extinguishing image frames sequenced after the current screen-extinguishing image frame in a carousel mode; and sequentially displaying the current screen-extinguishing image frame and other screen-extinguishing image frames in the display equipment, and switching the display equipment from the screen-extinguishing display mode to the normal display mode when the last frame is displayed.
In this embodiment, when detecting a movement signal for a display device in the terminal 102, the terminal 102 may acquire a current screen-extinguishing image frame and other screen-extinguishing image frames ordered after the current screen-extinguishing image frame, and first display the current screen-extinguishing image frame and the other screen-extinguishing image frames in the display device, and when displaying the last frame, the terminal 102 may switch the screen-extinguishing display mode of the display device to the normal display mode. Specifically, when the screen-off display is performed, the terminal 102 senses an action of the user, for example, lifting the terminal 102, the display screen of the terminal 102 may still normally rotate the current frame to other frames sequenced after the current frame, for example, a default image of the start frame or a star of the last frame, and enter the normal display mode (normal) from the screen-off display mode (idle).
Through the embodiment, when detecting the movement of the terminal 102, the terminal can display the current screen-extinguishing image frame and other image frames sequenced after the current screen-extinguishing image frame, and can switch the display mode, thereby realizing the dynamic display of the screen-extinguishing image and effectively slowing down the aging of the screen pixel points.
In one embodiment, further comprising: and responding to the awakening instruction, acquiring a starting frame in at least two screen-extinguishing image frames, generating an awakening image according to the screen-extinguishing image and the unlocking image corresponding to the starting frame, and displaying the awakening image in the display equipment.
In this embodiment, the wake-up instruction may be triggered in various manners, for example, clicking on a display device of the terminal 102 or pressing a wake-up button of the terminal 102. The terminal 102 may acquire a start frame of the at least two screen-off image frames when detecting the wake-up instruction, and generate a wake-up image according to the screen-off image and the unlock image corresponding to the start frame and display the wake-up image in the display device. Specifically, as shown in fig. 7, fig. 7 is an interface schematic diagram of a wake-up image in one embodiment. When the terminal 102 goes out of the screen display state, the terminal 102 senses that a user clicks a screen or presses a power key, the display screen enters a normal display state (normal) from a screen display mode (idle), and the current frame being played is directly jumped to a screen display image corresponding to the initial frame, and an unlocking picture is generated in cooperation with an unlocking schematic image, such as a fingerprint pattern of fingerprint unlocking. For example, if the screen-off display image frame has four frames, when the screen-off display is played to the third frame or the last frame, the terminal 102 senses that the user clicks the screen, and displays an unlock image composed of the start frame image and the unlock prompt as a wake-up image, as shown in fig. 7.
According to the embodiment, the terminal 102 can switch the screen-extinguishing image to the initial frame when the wake-up instruction is detected, and generate the wake-up interface comprising the initial frame and the unlock prompt, so that dynamic display of the screen-extinguishing image can be realized.
