Referring to fig. 1, a schematic flowchart of an embodiment of a method for controlling display of a display screen according to the present application is shown, where the method includes the following steps, and referring to fig. 2, the method is shown in a schematic partial structure diagram of the display screen according to the embodiment of the present application.
101, setting a circular arc auxiliary line 10 at a position close to the edge of the display screen 100, wherein the circular arc auxiliary line 10 divides the display screen 100 into a complete display area 20, a non-display area 30 and a transition display area 40. The plurality of critical pixel cells 42 intersecting the circular arc auxiliary line 10 and the plurality of transition pixel cells 44 adjacent to the circular arc auxiliary line 10 and close to the full display area 20 together form the transition display area 40, and the center of the circular arc auxiliary line 10 is located in the full display area 20.
Specifically, the display screen 100 may be a display screen of a mobile phone, a camera, an Ipad, a watch, or other smart wearable device. The display screen 100 may have different shapes, such as rectangular, circular-like, oval, or other shapes, corresponding to different end products. Wherein the non-display area 30 is located at an edge position of the display screen 100, below which wiring, etc. can be used.
Referring to fig. 3, taking the display screen of the mobile phone or Ipad as an example, the display screen 100 is rectangular and includes four corners, and the four corners include the non-display area 30 and the transition display area 40. The full display area 20 is located in the middle of the display screen 100 and occupies most of the area of the display screen 100, and the transitional display area 40 is located between the full display area 20 and the non-display area 30. The display area of the display screen 100 is composed of the full display area 20 and the transitional display area 40. The critical pixel units 42 are intersected with the auxiliary circular arc line 10, so that the edges of at least four corner positions of the display area of the display panel 100 are circular arc-shaped.
Referring to fig. 4, it can be understood that in other embodiments, such as a circular watch, the edge of the whole display area is circular, i.e. the transition display area 40 is surrounded by a circle, which may be circular or elliptical.
Specifically, the step of setting the arc auxiliary line 10 at the edge position of the display screen 100 includes: the radius of the arc auxiliary line 10 is calculated according to the following formula:
L＝R1/h；
R2＝L×h；
where R1 is the target radius of the arc auxiliary line 10, R2 is the actual radius of the arc auxiliary line 10, and h is the height of the pixel unit in the display screen, as shown in fig. 5. The target radius is the radius proposed by the user according to the actual product shape.
With continued reference to FIG. 2:
102: the circular arc auxiliary line 10 divides each of the critical pixel units 42 into a first portion 422 near the full display area 20 and a second portion 424 near the non-display area 30, wherein the ratio of the area of the first portion 422 to the total area of the critical pixel units 42 is greater than or equal to a predetermined value, and the critical pixel unit 42 is defined as an effective pixel unit, otherwise, the critical pixel unit 42 is defined as an ineffective pixel unit.
Specifically, the preset proportion value is 10% -40%. That is, the ratio of the area of the first portion 422 in each of the critical pixel units 42 in the transitional display area 40 to the total area of the critical pixel units is greater than or equal to any one of 10% -40%, that is, the critical pixel unit 42 is defined as an effective pixel unit. The preset value of the ratio is different for different product requirements. In one embodiment, the predetermined ratio is 20%.
103: the aperture ratio of the critical pixel cell 42 is determined by the ratio of the area of the first portion 422 to the entire critical pixel cell 42. That is, the larger the area of the first portion 422 in each of the critical pixel units 42, the larger the aperture ratio thereof, that is, the larger the light emitting luminance of the critical pixel unit 42.
104: the aperture ratio of each transition pixel unit 44 is set to be greater than the aperture ratio of the critical pixel units 42 in the same column and smaller than the aperture ratio of the pixel units in the full display area 20 in the same column.
In different embodiments, the number of the transition pixel units 44 in the same column of pixel units is 1 or more. In one embodiment, the aperture ratio of the same column of pixel cells gradually increases from the critical pixel cell 42 to the transition pixel cell 44 to the first pixel cell of the adjacent transition pixel cell 44 within the full display area 20. In other embodiments, the above transition may be an equal difference change, so that the aperture ratio of each pixel unit in the transition display area 40 to the full display area 20 changes more uniformly.
Specifically, the aperture ratio in the full display area 20 is the largest aperture ratio in the entire display area, and the aperture ratios of each pixel unit in the full display area 20 are all equal. Since the pixel units are physically isolated in hardware, the effective photosensitive area of the pixel units is necessarily smaller when the density of the pixel units is higher, and therefore, the aperture ratio of each pixel unit cannot reach 100%. The aperture ratio of each pixel unit in the full display area 20 is defined as 1 in the present application. Therefore, the critical pixel unit 42 of the transitional display area 40 is necessarily smaller than the aperture ratio of the pixel unit in the complete display area 20, a plurality of critical pixel units 42 with aperture ratios larger than 0 and smaller than 1 and a plurality of transitional pixel units 44 are arranged between the non-display area 30 and the complete display area 20 as intermediate brightness transitions, and in the same column of pixel units, the brightness of the transitional pixel unit 44 is larger than that of the critical pixel unit 42, so that the phenomenon of jaggy appearance at the edge of the screen can be greatly improved through the arrangement.
Specifically, the number of transition pixel units 44 in each column of pixel units is determined by the following method:
referring to fig. 2 and 3, the number of transition pixel units 44 is equal to the number of effective pixel units in the column and the number of effective pixel units in the adjacent column, and the number of effective pixel units in the column is greater than the number of effective pixel units in the adjacent column. The effective pixel units are effective pixel units in the transitional display area 40 and the full display area 20. Specifically, taking the 7 th column in fig. 2 as an example, for the 1/4 th part of the display screen, the number of the 7 th column effective pixel units is 1 more than the 6 th column effective pixel units on the left side of the 7 th column effective pixel units, so that the number of the 7 th column transition pixel units 44 of the display screen 100 for the 1/4 part is 1. Referring to fig. 3, it can be appreciated that for the entire display screen 100, there are two more active pixel elements in column 7 relative to column 6, and thus there are two transition pixel elements 44 in column 7, one in the upper left corner and the other in the lower left corner.
Taking the column 5 of fig. 2 as an example, for the 1/4 portion of the display screen 100, there are 2 more column 5 active pixel elements relative to the column 4 to the left thereof. The number of transition pixel cells 44 for column 5 of the display screen for this section 1/4 is thus 2.
It will be appreciated that for the right area of the display screen 100 shown in fig. 3, the number of active pixel units in each column is greater than or equal to the number of adjacent active pixel units in the column to the right.
Further, in another embodiment, in the same row of pixel units, if the aperture ratio of the critical pixel unit 42 is smaller than or equal to the first threshold value and the number of the transition pixel units 44 in the row is smaller than or equal to the second threshold value, the number of the transition pixel units 44 in the row is increased, so that the aperture ratio from the critical pixel unit 42 to the first pixel unit of the adjacent transition pixel units 44 in the full display area 20 is uniformly changed.
Taking the 11 th column of fig. 2 as an example, as can be seen from fig. 2, the proportion of the area of the first portion 422 of the critical pixel unit 42 to the total area of the critical pixel unit 42 is small, and it is assumed that the proportion is 20%. For the 1/4 portion of the display screen 100, the 11 th column is 1 more active pixel elements than the 10 th column to the left. At this time, the number of the transition pixel units 44 in the 11 th column is 1, that is, in the transition from the transition display area 40 to the full display area 20, the aperture ratio of the first pixel unit in the 11 th column from the critical pixel unit 42 to the transition pixel unit 44 to the full display area 20 close to the transition display area 40 changes as follows: 0.2,0.6,1. The magnitude of this change is somewhat large, so that the present situation of jaggy feeling appearing on the edge of the display screen 100 can be further improved. When the opening ratio of the critical pixel unit 42 is less than or equal to the first threshold value, and the number of the transition pixel units 44 in the column is less than or equal to the second threshold value, the number of the transition pixel units 44 in the column, specifically, the number of the transition pixel units 44 in the column, may be increased, which is not limited herein.
In one embodiment, the first threshold is 0.2-0.4 and the second threshold is 1 or 2.
Referring to fig. 5, in one embodiment, for the effective critical pixel units 42 in the transitional display area 40, the black matrix 50 is disposed at the area of the arc auxiliary line 10 near the non-display area 30, i.e. the second portion 424, of each of the effective critical pixel units 42, so as to reduce the aperture ratio of the effective critical pixel unit 42.
Referring to fig. 6, in another embodiment, the effective critical pixel unit 42a uses 2 black matrixes 50a to cross-block the portion close to the non-display area 30, so as to reduce the aperture ratio of the effective critical pixel unit 42.
Referring to fig. 7, in another embodiment, the effective critical pixel unit 42b is covered by a black matrix 50b to cover any part of the area of the effective critical pixel unit 42. The blocked area is equal to the area of the effective critical pixel unit 42b located on the arc auxiliary line 10 near the non-display area 30. Similarly, for the transition pixel unit 44, any partial area in the transition pixel unit 44 is blocked by the black matrix 50b, and the ratio of the blocked area to the total area of the transition pixel unit 44 is equal to the aperture ratio of the transition pixel unit 44.
The display screen 100 is formed by the above method, and the transition display area 40 is formed between the full display area 20 located in the middle of the display screen 100 and the non-display area 30 located at the edge. The critical pixel 42 in the transitional display area 40 is an effective critical pixel unit only if the ratio of the area of the first portion 422 to the total area of the critical pixel unit 42 is greater than or equal to a predetermined value, otherwise, it is an ineffective critical pixel unit. For an effective critical pixel cell 42, the ratio of the area of the first portion 422 to the total effective critical pixel cell 42 determines the aperture ratio of the effective critical pixel cell 42, i.e., the greater the area 422 of the first portion, the greater the brightness of the effective critical pixel cell 42. And a plurality of transition pixel units 44 are further arranged between the critical pixel unit 42 and the complete display area 20, so that the brightness of the critical pixel unit 42 to the transition pixel unit 44 and then to the complete display area 20 gradually increases and changes to smooth and improve the jaggy appearance of the screen edge and optimize the visual effect, and the display effect of a part of the display screen 100 after the above control method is applied is as shown in fig. 8.
The present application also provides a display screen 100, as shown in fig. 3 or 4. The display screen includes a full display area 20 located at a central position of the display screen 100, a non-display area 30 located at an edge position of the display screen 100, and a transition display area 40 located at the full display area 20 and the non-display area 30. The transitional display region 40 includes a plurality of critical pixel cells 42 and a plurality of transitional pixel cells 44 respectively disposed adjacent to the critical pixel cells 42. The plurality of adjacent critical pixel units 42 form a circular arc shape, and the aperture ratio of the critical pixel unit 42 is greater than 0 and smaller than 1. The aperture ratio of each transition pixel unit 44 is greater than the aperture ratio of the critical pixel units 42 in the same column and less than the aperture ratio of the pixel units in the full display area 20 in the same column.
Further, in one embodiment, the aperture ratio of the pixel units in the same column gradually increases from the critical pixel unit 42 to the transition pixel unit 44 to the first pixel unit adjacent to the transition pixel unit 44 in the full display area 20.
Specifically, the specific structure of the display screen 100 and the arrangement of the black matrix are as described in the above embodiments, which are not repeated herein.
An embodiment of the present application further provides a display screen 100, as shown in fig. 3 and 4. The display panel 100 is as described in the above embodiments, and whether each of the critical pixel cells 42 in the transition display area 40 on the display panel 100 is an effective pixel cell or not, and the aperture ratios for the effective critical pixel cells 42 and the transition pixel cells 44 are set by the method described in the above embodiments.
Specifically, for the display screen 100 with the arc-shaped display area, the whole terminal is also made to have the appearance of an arc-shaped edge, and at this time, the corner of the rectangular display screen 100 is a chamfer or forms an arc chamfer to match the shape of the terminal. Of course, if the position of the terminal for placing the display screen is large enough, the corner of the rectangular display screen may not be chamfered or rounded.
Referring to fig. 9, an embodiment of the present application further provides a terminal 300, where the terminal 300 includes the display screen 100. The specific terminal 300 can be a mobile phone, an IPad, a smart wearable device, a digital audio/video player, an electronic reader, a handheld game console, a vehicle-mounted electronic device, a digital camera, a printer, and the like.
