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 this application, the terms "first," "second," and the like are used merely to distinguish between descriptions, are not used to indicate a 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, the 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 via the bus 10, the memory 12 storing instructions executable by the processor 11, the instructions being executable by the processor 11 to cause the electronic device 1 to perform 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, the display carrier 13 may be a display screen of the electronic device 1, and the display screen may be controlled by a driving chip.
In an embodiment, referring to fig. 2, the display carrier 13 includes at least two display areas with different pixel densities, namely a first display area L and a second display area H. The electronic device 1 is configured to obtain pixel densities of different display areas on the display carrier 13, and adjust a display effect of the display carrier 13 in a display area with a high pixel density based on the pixel densities of the two to change a distinction degree of the different display areas on a boundary.
In one embodiment, the pixel density of the first display area L may be smaller than the pixel density of the second display area H. For example, on the mobile phone upper screen, the front camera is arranged below a first display area L of the display screen, and the pixel density of the first display area L is lower than that of a second display area H, so that the front camera has higher light transmittance. At this time, a large drop in pixel density on the boundary between the first display region L and the second display region H causes a visual boundary, and therefore, it is necessary to process the boundary.
Please refer to fig. 3, which is a display adjustment method according to an embodiment of the present application, which can be executed by the electronic device 1 shown in fig. 1 and can be applied to the scene shown in fig. 2 to realize display adjustment for display areas with different pixel densities on the display carrier 13, and based on the difference of the pixel densities, display adjustment is performed in the display areas with high pixel densities to change the distinction degree of the different display areas on the boundary. The method comprises the following steps:
step 301: a first pixel density of a first display area L and a second pixel density of a second display area H of the display carrier 13 are acquired, wherein the first pixel density is smaller than the second pixel density.
In this step, the display carrier 13 takes the display screen of the mobile phone as an example, and the first display area L on the display screen is provided with an under-screen camera. When the mobile phone is started, the display screen is electrified, and the first pixel density of the first display area L and the second pixel density of the second display area H are detected respectively, wherein the first pixel density is smaller than the second pixel density.
Step 302: the display state in the display carrier 13 corresponding to the second display area H is adjusted 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 with respect to the first display area L, and visually, the resolution difference between the resolution of the second display area H and the resolution of the first display area L is large, so that the visual effect is not good, and thus, 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 area L is adjacent to the second display area H. Step 302 may include: the lighting pixel parameters of the transition area W are calculated based on the first pixel density and the second pixel density, the transition area W being located in the second display area H and within a preset area from the boundary of the first display area L. The second display area H of the display carrier 13 is driven for display in accordance with the calculated lighting pixel parameters of the transition area W.
In the above steps, in the scene of the under-screen camera, the second display area H with high pixel density is adjacent to the first display area L with low pixel density, and the boundary between the two areas is a visual boundary due to the fall of the pixel density. By setting the transition region W in the second display region H of high pixel density, the size of the transition region W can be set according to the actual scene. Based on the pixel density drop 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 distinction degree of the first display area L and the second display area H on the boundary.
According to the display adjustment 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 two to reduce the distinction degree of the different display areas on the boundary.
Please refer to fig. 4A, which is a display adjustment method according to an embodiment of the present application, which can be executed by the electronic device 1 shown in fig. 1 and can be applied to the scene shown in fig. 2 to realize display adjustment for display areas with different pixel densities on the display carrier 13, and based on the difference of the pixel densities, display adjustment is performed in the display areas with high pixel densities to change the distinction degree of the different display areas on the boundary. The method comprises the following steps:
step 401: a first pixel density of a first display area L of the display carrier 13 and a second pixel density of a second display area H are acquired, 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: the first lighting pixel ratio of the first display area L and the second lighting pixel ratio of the second display area H are acquired, respectively.
In this step, after the display screen is powered on, the corresponding pixel point is turned on under the control of the control chip according to the display content. Fig. 4B is a partially enlarged schematic view of the boundary between the first display area L and the second display area H shown in fig. 2. The white point P represents a light pixel point, and the black point Q represents a black pixel point. Before being adjusted, one pixel is lit and three pixels are lit and black in the first display area L as seen in the row direction. In the second display area H, all the pixels are turned on, which results in excessive pixel density variation at the boundary and visually causes a black border.
In one display area, the ratio of the light-up pixel to the light-down pixel is referred to as the light-up pixel ratio. Based on this, first, the first lighting pixel ratio of the first display area L and the second lighting pixel ratio of the second display area H are detected, respectively. As shown in fig. 4B, in the first display area L, one pixel is turned on, and then three pixels are turned on, and the ratio of the turned-on pixels is 1/4, and the pixels in the second display area H are all turned on, and the ratio of the second turned-on pixels is 1.
Step 403: and 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 increase as a lighting pixel parameter.
In this step, the preset ratio may be set according to the actual scene. For example, ppi (pixel density) of the first display area L is one fourth of ppi of the second display area H, and ppi is increased from the direction toward the second display area H to the same ppi as the second display area H by simulating the arrangement of the Pixels in the first display area L. That is, assuming that the preset ratio is 2 times, the first lighting pixel ratio 1/4 is enlarged by 2 times to become 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 an engineering error within 5%.
Step 404: in the second display region H, the transition region W in the display carrier 13 is controlled to display in accordance with the third lighting pixel ratio.
In this step, as shown in fig. 4C, in the second display area H, a transition area W is simulated. If the edges processed are longitudinal (column direction), a transition in the row direction is required. In the first display area L, the first lighting pixel ratio is 1/4 as seen in the row direction. In the transition area W, the control chip lights one pixel point according to the third lighting pixel proportion of 1/2, and then the pixel point is black. Starting from the boundary of the first display area L, the proportion gradually increases to a second lit pixel proportion of the second display area H. In the transition area W, due to the resolution change, the brightness of the screen display may fluctuate, and brightness adjustment may be performed on the transition area W, or brightness asymptotic transition may be performed at the same time.
In one embodiment, analogous to FIG. 4C, the boundary position changes from portrait to landscape as shown in FIG. 4D. The transition area W is seen from the vertical direction, and two consecutive pixels are turned from the black pixel of the first display area L to the black pixel of the transition area W, and then to the pixel of the second display area H to be fully lit.
Referring to fig. 5A, an embodiment of a display adjustment method is shown, which can be performed by the electronic device 1 shown in fig. 1 and can be applied to the scene shown in fig. 2 to implement display adjustment for display areas with different pixel densities on the display carrier 13, and based on the difference of the pixel densities, display adjustment is performed in the display areas with high pixel densities to change the distinction degree of the different display areas on the boundary.
The method comprises the following steps:
step 501: a first pixel density of a first display area L of the display carrier 13 and a second pixel density of a second display area H are acquired, 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: a first distance from each pixel point in the transition area W to the boundary of the first display area L is detected, and a first brightness of the first display area L and a second brightness of the second display area H are detected respectively.
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. Each pixel point in the transition area W has a first distance from the boundary of the first display area L, and a plurality of corresponding first distances are respectively obtained. And detects the first luminance and the second luminance 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 the boundary of the first display region L. If the display area is in a straight line segment shape, the positional 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, and the line is shown in fig. 5B after simplification, wherein the point N is the nth pixel point in the transition area W, N is a positive integer, and the first distance from the point N to the boundary of the first display area L is x n The width of the transition area W is x w The corresponding ratio of the point N is R n The following formula can be used for calculation:
in an embodiment, the first distance may also be a distance from each pixel point in the transition area W to the boundary of the second display area H. If the first display area L, the second display area H, and the transition area W in fig. 5C are arc-shaped, the positional relationship between the first display area L and the second display area H in fig. 5C may be simplified to be a line, and after the simplification, the line is shown in fig. 5D, where the inner arc is the boundary line between the first display area L and the transition area W, the outer arc is the boundary of the transition area W in the second display area H, and the inner arc and the outer arc are concentric. Set point m (x) m ，y m ) Is a transition zoneThe pixel points in the domain W cross the center of the circle and point m as rays and cross the inner arcs at points i (x i ，y i ) Intersecting the outer arc at point o (x o ，y o ). The first distance corresponding to the point m is the distance from the point m to the outer arc, and the ratio corresponding to the point m can be calculated by adopting the following formula:
step 504: and according to the ratio, the first brightness and the second brightness, calculating the 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＝L l +(L h -L l )*R j
wherein Lj is the third brightness corresponding to the j-th pixel point in the transition area W, L l For a first brightness, L h For a second brightness, R j The ratio corresponding to the j-th 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 area H, the transition area W on the display carrier 13 is controlled to display according to the correspondence 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 correspondence between the third brightness calculated in step 504 and each pixel point. So that the display brightness transitions increasingly from the first brightness of the first display area L to the second brightness of the second display area H.
Please refer to fig. 6A, which is a display adjustment method according to an embodiment of the present application, which can be executed by the electronic device 1 shown in fig. 1 and can be applied to the scene shown in fig. 2 to realize display adjustment for display areas with different pixel densities on the display carrier 13, and based on the difference of the pixel densities, display adjustment is performed in the display areas with high pixel densities to change the distinction degree of the different display areas on the boundary. The method comprises the following steps:
step 601: a first pixel density of a first display area L of the display carrier 13 and a second pixel density of a second display area H are acquired, 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: the first luminance of the first display region L and the second luminance of the second display region H are detected based on the first pixel density and the second pixel density, respectively.
Step 603: and acquiring a transition gray scale value of a preset transition area W based on the first brightness and the second brightness, wherein the transition area W is positioned in the second display area H and is positioned in a preset area of the boundary of the first display area L.
In this step, the definition of the transition area W is detailed in the description of the method embodiment described above. The corresponding relation between the first brightness and the second brightness and the transition gray scale value can be set, and after the first brightness and the second brightness on the current display screen are detected, the relation table is searched to find the corresponding transition gray scale value. The transition gray scale value may range from 0 to 255.
Step 604: the transition area W on the display carrier 13 is controlled to display according to the transition gray scale value such that the fourth luminance in the transition area W is between the first luminance and the second luminance.
In the step, partial pixel points are randomly displayed in the transition area W according to the transition gray scale values, so that black pixel points are randomly inserted in the transition area W.
