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 first arc auxiliary line 10 and a second arc auxiliary line 10a at the position close to the edge of a display screen 100, wherein the first arc auxiliary line 10 and the second arc auxiliary line 10a are arranged at intervals, the first arc auxiliary line 10 and the second arc auxiliary line 10a divide the display screen into a complete display area 20, a non-display area 30 and a transition display area 40, and the circle centers of the first arc auxiliary line 10 and the second arc auxiliary line 10a are positioned in the complete display area 20.
In the present embodiment, in which a plurality of transition pixel cells 42 intersecting the first arc auxiliary line 10 or the second arc auxiliary line 10a form the transition display area 40, this case corresponds to a case where the distance between the first arc auxiliary line 10 and the second arc auxiliary line 10a is relatively small, and in order to facilitate distinguishing between the transition pixel cell intersecting the first arc auxiliary line 10 defined as 42a and the transition pixel cell intersecting the second arc auxiliary line 10a defined as 42b in the present embodiment. In other embodiments, the distance between the first arc auxiliary line 10 and the second arc auxiliary line 10a may be relatively large, and in this case, a transition pixel unit 42c that does not intersect with the first arc auxiliary line 10 or the second arc auxiliary line 10a exists between the first arc auxiliary line 10 and the second arc auxiliary line 10a, as shown in fig. 3. The transition display area 40 at this time is formed by a plurality of transition pixel cells 42a and 42b intersecting the first arc auxiliary line 10 or the second arc auxiliary line 10a and a plurality of transition pixel cells 42c located between the first and second arc auxiliary lines 10, 10a and not intersecting the first or second arc auxiliary lines 10, 10 a.
Alternatively, in an embodiment, the first arc auxiliary line 10 is arranged in parallel with the second arc auxiliary line 10 a. In other embodiments, the first arc auxiliary line 10 and the second arc auxiliary line 10a may be in a non-parallel relationship, as long as a transition display area 40 can be added between the non-display area 30 and the full display area 20 of the display screen 100. Corresponding to various embodiments, the distance between the first and second arc auxiliary lines 10 and 10a is any one value of 1 to 3 times the height of the pixel unit.
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. 4, 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 transition pixel units 42 are intersected with the first arc auxiliary line 10 or the second arc auxiliary line 10a, so that the edges of at least four corner positions of the display area of the display screen 100 are arc-shaped.
Referring to fig. 5, 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, in an embodiment, the radius of the first arc auxiliary line 10 and/or the second arc auxiliary line 10a is calculated according to the following formula:
L＝R1/h；
R2＝L×h；
where R1 is a target radius of the first or second arc auxiliary line 10 or 10a, R2 is an actual radius of the first or second arc auxiliary line 10 or 10a, and h is a height of a pixel unit in the display screen, as shown in fig. 6. The target radius is the radius proposed by the user according to the actual product shape.
102: the pixel aperture ratio of the transition pixel unit 42 in the transition display area 40 is set to be greater than 0 and smaller than the pixel aperture ratio of the pixel unit in the full display area 20.
It should be noted that the aperture ratio of the pixel units 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 transitional pixel units 42 in the transitional display area 40 are necessarily smaller than the aperture ratio of the pixel units in the complete display area 20, and a plurality of transitional pixel units 42 with aperture ratios greater than 0 and less than 1 are arranged between the non-display area 30 and the complete display area 20 as the intermediate brightness transition, so that the phenomenon of jaggy feeling at the edge of the screen can be greatly improved, and the display effect of a part of the display screen 100 after the above control method is applied is as shown in fig. 7.
With continued reference to FIG. 2:
in one embodiment, the first arc auxiliary line 10 divides each transition pixel unit 42a intersecting the first arc auxiliary line 10 into a first portion 422 near the full display area 20 and a second portion 424 near the non-display area 30. If the first ratio of the area of the first portion 422 to the transitional pixel unit 42a is greater than or equal to the first preset value, the pixel transitional pixel unit 42a is defined as an effective transitional pixel unit, otherwise, the transitional pixel unit 42a is defined as an ineffective transitional pixel unit, and the aperture ratio of the effective transitional pixel unit 42a is determined according to the first ratio.
In this embodiment, the first preset value is 20%. In other embodiments, the first preset value may be any one of 20% to 40%. That is, the ratio of the area of the first portion 422 in each transition pixel unit 42a in the transition display area 40 to the total area of the transition pixel unit 42a is greater than or equal to any one of 20% -40%, that is, the transition pixel unit 42a is defined as an effective pixel unit.
In one embodiment, the second arc auxiliary line 10a divides each transition pixel unit 42b intersected with the second arc auxiliary line 10a into a third portion 422b close to the full display area 20 and a fourth portion 424b close to the non-display area 30, and determines the aperture ratio of the transition pixel unit 42b according to the ratio of the larger area of the third portion 422b and the fourth portion 424b to the total area of the transition pixel unit 42 b. Since the second arc auxiliary line 10a is disposed adjacent to the full display area 20, the aperture ratio of one pixel unit among the pixel units adjacent to the transition pixel unit 42b intersecting with the second arc auxiliary line 10a is 1, that is, the pixel unit located in the full display area 20, so that the aperture ratio of the transition pixel unit 42b intersecting with the second arc auxiliary line 10a can be prevented from being far different from the aperture ratio 1, and the phenomenon of abrupt change in aperture ratio between the adjacent pixel units can be avoided.
Further, in the embodiment where the distance between the first and second arc auxiliary lines 10 and 10a is relatively large, as shown in fig. 3, the first and second arc auxiliary lines 10 and 10a include a transition pixel unit 42c between them, which does not intersect with the first arc auxiliary line 10 or the second arc auxiliary line 10 a. The aperture ratio of the transition pixel cell 42c is set to be between the aperture ratio of the transition pixel cell 42a intersecting the first arc auxiliary line 10 in the same row and the aperture ratio of the transition pixel cell 42b intersecting the second arc auxiliary line 10a in the same row. With this arrangement, the aperture ratios of the plurality of transition pixel units 42 in the transition display area 40 are not too far apart, and thus, the abrupt change of the aperture ratios of the adjacent transition pixel units 42 is avoided. If a plurality of transition pixel units 42c which do not intersect the first or second arc auxiliary lines 10, 10a are included between the first and second arc auxiliary lines 10, 10a in the same column, the variation of the aperture ratio of the plurality of transition pixel units 42c which do not intersect the first or second arc auxiliary lines 10, 10a between the first and second arc auxiliary lines 10, 10a in the same column is set to be equal.
Further, in an embodiment, in a special case, according to the above method, if a case occurs in which the aperture ratio of the transition pixel cell 42a intersecting the first arc auxiliary line 10 is larger than the aperture ratio of the transition pixel cell 42b intersecting the second arc auxiliary line 10a in the same column, the aperture ratio of the transition pixel cell 42a intersecting the first arc auxiliary line 10 in the column is interchanged with the aperture ratio of the transition pixel cell 42b intersecting the second arc auxiliary line 10 a. As shown in column 11 in row 6 and row 8 of fig. 3.
Still further, in another embodiment, if a transition pixel unit 42c that does not intersect with the first or second arc auxiliary line 10, 10a is included between the first and second arc auxiliary lines 10, 10a, the aperture ratio of the transition pixel unit 42c is defined to be greater than the aperture ratio of the transition pixel unit 42a that intersects with the first arc auxiliary line 10 in the same column and less than the aperture ratio of the transition pixel unit 42b that intersects with the second arc auxiliary line 10 a. Alternatively, the aperture ratios of the transition pixel unit 42c and the transition pixel unit 42a intersecting the first arc auxiliary line 10 and the transition pixel unit 42b intersecting the second arc auxiliary line 10a in the same column are made to vary with an equal difference. The setting can better smooth and improve the saw-tooth feeling of the edge of the screen and optimize the visual effect.
Referring to fig. 6, in an embodiment, for the effective transition pixel units 42a in the transition display area 40, the black matrix 50 is disposed at a position where each transition pixel unit 42a is located in the area of the first arc auxiliary line 10 close to the non-display area 30, that is, the second portion 424, so as to reduce the aperture ratio of the effective transition pixel unit 42.
Referring to fig. 8, in another embodiment, the effective transition pixel unit 42a uses 2 black matrixes 50a to cross-block a portion close to the non-display area 30, so as to reduce the aperture ratio of the effective transition pixel unit 42 a.
Referring also to fig. 9, in yet another embodiment, the effective transition pixel unit 42a is covered by a black matrix 50b to cover any part of the area of the effective transition pixel unit 42 a. The blocked area is equal to the area of the effective transition pixel unit 42a located in the first arc auxiliary line 10 near the non-display area 30.
Similarly, for the transition pixel unit 42b intersecting the second arc auxiliary line 10a and the transition pixel unit 42c located between the first and second arc auxiliary lines 10, 10a and not intersecting the first or second arc auxiliary line 10, 10a, any partial area of the transition pixel unit 42b (or 42c) may be blocked by the black matrix 50b, and the ratio of the blocked area to the total area of the transition pixel unit 42b (or 42c) is equal to the aperture ratio of the transition pixel unit 42b (or 42 c).
The display screen 100 or 100a formed by the above method forms a transition display area 40 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 transitional display area 40 includes a plurality of transitional pixel units 42, so that the brightness change from the non-display area 30 to the full display area 20 is buffered, thereby smoothing and improving the jaggy feeling of the screen edge and optimizing the visual effect.
An embodiment of the present application further provides a display screen 100 or 100a, as shown in fig. 2 to 5, where the display screen 100 or 100a is as described in the above embodiments, whether each transition pixel unit 42a in the transition display area 40 on the display screen 100 or 100a is an effective pixel unit, and the aperture ratio of the transition pixel unit 42 is set by the method described in the above embodiments, which is not repeated herein.
Specifically, for the display screen 100 or 100a 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 or 100a 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. 10, 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.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
