Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, are not used to indicate a narrative number, and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the present embodiment provides an electronic apparatus 1 including: at least one processor 11, a memory 12 and a display carrier 13, a display panel of the display carrier 13 comprising: one of an LED panel, a small-pitch display screen, a miniLED panel, or a microLED panel. One processor is illustrated in fig. 1. The processor 11, the memory 12 and the display carrier 13 are connected by a bus 10, and the memory 12 stores instructions executable by the processor 11, and the instructions are executed by the processor 11, so that the electronic device 1 can execute all or part of the flow of the method in the embodiments described below.
In an embodiment, the electronic device 1 may be a mobile phone, a notebook computer, or the like, and the display carrier 13 may be a display screen of the electronic device 1, where the display screen may be controlled by a driving chip.
In one embodiment, referring to fig. 2, the display carrier 13 includes at least two display regions with different pixel densities, i.e., a first display region L and a second display region H. The electronic device 1 is configured to respectively obtain pixel densities of different display areas on the display carrier 13, and adjust a display effect of the display carrier 13 in a high-pixel-density display area based on the pixel densities of the two, so as to change a degree of distinction between the different display areas on a boundary.
In one embodiment, the pixel density of the first display region L may be less than the pixel density of the second display region H. For example, on the screen of the mobile phone, the front-facing camera is arranged below the first display area L of the display screen, and the pixel density of the first display area L is lower than that of the second display area H, so that the front-facing camera has higher light transmittance. At this time, a large difference in pixel density causes a visual boundary at the boundary between the first display region L and the second display region H, and therefore, the boundary needs to be processed.
Please refer to fig. 3, which is a display adjustment method according to an embodiment of the present application, and the method can be executed by the electronic device 1 shown in fig. 1 and can be applied in the scenario shown in fig. 2 to implement display adjustment in a display area with high pixel density for display areas with different pixel densities on the display carrier 13 based on the difference of the pixel densities thereof, so as to change the degree of difference between the different display areas on the boundary. The method comprises the following steps:
step 301: a first pixel density of the first display area L and a second pixel density of the second display area H of the display carrier 13 are obtained, wherein the first pixel density is smaller than the second pixel density.
In this step, the display carrier 13 takes a display screen of a mobile phone as an example, and a first display area L on the display screen is provided with an off-screen camera. When the mobile phone is started, the display screen is powered on, and a first pixel density of the first display area L and a second pixel density of the second display area H are respectively detected, wherein the first pixel density is smaller than the second pixel density.
Step 302: and adjusting the display state of the display carrier 13 corresponding to the second display area H according to the first pixel density and the second pixel density.
In this step, the second display area H belongs to a high pixel density area relative to the first display area L, and visually, the visual effect is poor due to the difference between the resolution of the second display area H and the resolution of the first display area L, so the display state of the second display area H corresponding to the high pixel density in the display carrier 13 can be improved by adjusting.
In one embodiment, the first display region L is adjacent to the second display region H. Step 302 may include: based on the first pixel density and the second pixel density, a lighting pixel parameter of a transition region W, which is located in the second display region H and within a preset region from a boundary of the first display region L, is calculated. The second display area H of the display carrier 13 is driven for display in dependence on the calculated illuminated pixel parameter of the transition area W.
In the above steps, in the scene of the off-screen camera, the second display region H with high pixel density is adjacent to the first display region L with low pixel density, and the boundary between the two regions causes a visual boundary due to the difference of pixel density. By providing the transition region W in the second display region H with a high pixel density, the size of the transition region W can be set according to an actual scene. Based on the pixel density difference at the boundary, the lighting pixel parameters of the transition area W are calculated, and then the display carrier 13 is controlled to display according to the calculated lighting pixel parameters of the transition area W, so as to reduce the difference between the first display area L and the second display area H on the boundary.
In the display adjusting method, the pixel densities of different display areas on the display carrier 13 are respectively obtained, and the display effect of the display carrier 13 is adjusted in the display area with high pixel density based on the pixel densities of the different display areas, so that the difference of the different display areas on the boundary is reduced.
Please refer to fig. 4A, which is a display adjustment method according to an embodiment of the present application, and the method can be executed by the electronic device 1 shown in fig. 1 and can be applied in the scenario shown in fig. 2 to implement display adjustment in a display area with a high pixel density based on the difference of the pixel densities of display areas with different pixel densities on the display carrier 13, so as to change the degree of difference between the different display areas on the boundary. The method comprises the following steps:
step 401: a first pixel density of the first display area L of the display carrier 13 and a second pixel density of the second display area H are obtained, wherein the first pixel density is smaller than the second pixel density. See the description of step 301 in the above embodiments for details.
Step 402: a first lighting pixel proportion of the first display region L and a second lighting pixel proportion of the second display region H are acquired, respectively.
In this step, after the display screen is powered on, the corresponding pixel points are lighted up under the control of the control chip according to the display content. Fig. 4B is a partially enlarged schematic view of the junction between the first display region L and the second display region H shown in fig. 2. Wherein, white point P represents a lighted pixel, and black point Q represents a blackened pixel. Before the adjustment, one pixel point is lighted up and three pixel points are blacked out in the first display area L from the line direction. And all pixel points are lightened in the second display area H, so that the density change of the pixels at the junction is overlarge, and a black edge is visually caused.
In one display region, the ratio of the lit pixel to the lit black pixel is referred to as the lit pixel ratio. Based on this, first, the first lighting pixel ratio of the first display region L and the second lighting pixel ratio of the second display region H are detected, respectively. As shown in fig. 4B, in the first display region L, when one pixel is lit up, and then three black pixels are lit up, as viewed in the row direction, the lit pixel ratio is 1/4, and when all the pixels in the second display region H are lit up, the second lit pixel ratio is 1.
Step 403: and gradually increasing the first lighting pixel proportion to be the same as the second lighting pixel proportion according to a preset proportion, and taking at least one third lighting pixel proportion obtained after each time of gradual increase as a lighting pixel parameter.
In this step, the preset ratio may be set according to an actual scene. For example, ppi (pixel Per inc) of the first display region L is one fourth of ppi of the second display region H, and ppi is gradually increased from a direction toward the second display region H to the same ppi as the second display region H by simulating an arrangement manner of pixel points in the first display region L. That is, assuming that the preset ratio is 2 times, the first lighting pixel ratio 1/4 is enlarged by 2 times to 1/2, and the third lighting pixel ratio is 1/2, which is the lighting pixel parameter of the transition region W.
In one embodiment, the term "identical" in this application allows for errors in engineering within 5%.
Step 404: in the second display region H, the transition region W in the display carrier 13 is controlled in accordance with the third lighting pixel ratio to display.
In this step, as shown in fig. 4C, a transition region W is simulated in the second display region H. If the processed edge is vertical (column direction), a transition in the row direction is needed. In the first display region L, the first lighting pixel ratio is 1/4 as viewed in the row direction. In the transition area W, the control chip lights up one pixel and then black one pixel according to the third lighting pixel ratio 1/2. Starting from the border of the first display region L, it is scaled up gradually to a second lit pixel scale of the second display region H. In the transition area W, the screen display brightness fluctuates due to the change of the resolution, and the brightness adjustment can be performed on the transition area W, or the brightness asymptotic transition can be performed at the same time.
In one embodiment, analogous to FIG. 4C, the boundary position changes from a longitudinal direction to a transverse direction as shown in FIG. 4D. The transition area W is seen longitudinally, two continuous black pixel points from the first display area L are formed, one black pixel point from the transition area W is formed, and then the pixel point from the transition area W to the second display area H is fully bright.
Please refer to fig. 5A, which is an embodiment of a display adjustment method, which can be executed by the electronic device 1 shown in fig. 1 and can be applied to the scenario shown in fig. 2 to implement display adjustment in a display area with a high pixel density based on the difference of the pixel densities of display areas with different pixel densities on the display carrier 13, so as to change the degree of difference between the different display areas on the boundary.
The method comprises the following steps:
step 501: a first pixel density of the first display area L of the display carrier 13 and a second pixel density of the second display area H are obtained, wherein the first pixel density is smaller than the second pixel density. See the description of step 301 in the above embodiments for details.
Step 502: and detecting a first distance from each pixel point in the transition region W to the boundary of the first display region L, and respectively detecting a first brightness of the first display region L and a second brightness of the second display region H.
In this step, the boundary between the first display region L and the second display region H may be a straight line segment as shown in fig. 4C, or may be an arc. A first distance exists between each pixel point in the transition region W and the boundary of the first display region L, and a plurality of corresponding first distances are obtained respectively. And detects first and second luminances of the two display areas, respectively.
Step 503: the ratio between each first distance and the width of the transition area W is calculated separately.
In this step, the first distance may be a distance from each pixel point in the transition region W to a boundary of the first display region L. If the display area is a straight line segment, the position relationship among the first display area L, the second display area H and the transition area W in fig. 4C can be simplified into a line, as shown in fig. 5B after the simplification, where the point N is the nth pixel point in the transition area W,n is a positive integer, and a first distance from the point N to the boundary of the first display region L is xnThe width of the transition region W is xwThen the ratio corresponding to the point N is RnThe following formula can be used for calculation:
Figure BDA0002367071320000111
in an embodiment, the first distance may also be a distance from each pixel point in the transition region W to a boundary of the second display region H. If the display area is circular arc as shown in fig. 5C, the positional relationship among the first display area L, the second display area H and the transition area W in fig. 5C can be simplified into a line, and the simplified display area is shown in fig. 5D, where the inner circular arc is the boundary line between the first display area L and the transition area W, the outer circular arc is the boundary line between the transition area W and the second display area H, and the inner circular arc and the outer circular arc are concentric. Setting point m (x)m，ym) The pixel points in the transition region W, passing through the center of circle and point m are taken as rays, and the rays are respectively intersected with the inner arc at point i (x)i，yi) Intersecting the outer arc at point o (x)o，yo). Then, the first distance corresponding to the point m is the distance from the point m to the outer arc, and the ratio of the point m to the outer arc can be calculated by using the following formula:
Figure BDA0002367071320000112
step 504: and according to the ratio, the first brightness and the second brightness, calculating to obtain third brightness corresponding to each pixel point as a lighting pixel parameter.
In this step, the third luminance may be calculated using the following formula:
Lj＝Ll+(Lh-Ll)*Rj
wherein Lj is a third brightness corresponding to the jth pixel point in the transition region W, and LlIs a first brightness, LhIs a second brightness, RjIs the ratio corresponding to the jth pixel point in the transition area W.
In one embodiment, the third brightness is between the first brightness and the second brightness.
Step 505: in the second display region H, the transition region W on the display carrier 13 is controlled to display according to the corresponding relationship between the third brightness and each pixel point.
In this step, the control chip controls the transition area W on the display carrier 13 to display according to the third brightness calculated in step 504 and the corresponding relationship between each pixel point. So that the display luminance is gradually transited from the first luminance of the first display region L to the second luminance of the second display region H.
Please refer to fig. 6A, which is a display adjustment method according to an embodiment of the present application, and the method can be executed by the electronic device 1 shown in fig. 1 and can be applied in the scenario shown in fig. 2 to implement display adjustment in a display area with a high pixel density based on the difference of the pixel densities of display areas with different pixel densities on the display carrier 13, so as to change the degree of difference between the different display areas on the boundary. The method comprises the following steps:
step 601: a first pixel density of the first display area L of the display carrier 13 and a second pixel density of the second display area H are obtained, wherein the first pixel density is smaller than the second pixel density. See the description of step 301 in the above embodiments for details.
Step 602: based on the first pixel density and the second pixel density, a first luminance of the first display region L and a second luminance of the second display region H are detected, respectively.
Step 603: and acquiring a transition gray-scale value of a preset transition region W based on the first brightness and the second brightness, wherein the transition region W is positioned in the second display region H and is in a preset region of the boundary of the first display region L.
In this step, please refer to the related description in the above embodiments of the method for the definition of the transition region W. The corresponding relationship between the first brightness and the second brightness and the transition gray scale value can be set as a relationship table, and after the first brightness and the second brightness on the current display screen are detected, the relationship table is searched to find the corresponding transition gray scale value. The transition gray scale value may range from 0 to 255.
