Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, a gradual-change picture displayed on a display screen is inspected by naked eyes manually, because one color of the gradual-change picture is displayed on the display screen as a row or a column of lamp beads (namely, as a row or a column of pixels), and the color missing perception of partial lamp beads or all lamp beads of the row or the column of lamp beads by human eyes is not obvious, whether the display screen jumps dust or not can not be accurately inspected, especially a display screen with small space, and because the space between adjacent rows or adjacent columns is small, whether the display screen jumps dust or not is more difficult to find.
To this end, the present invention solves the above-mentioned problems by performing stretch display on each color in a gradient picture so that each color of the gradient picture can continuously display a plurality of pixels (i.e., a plurality of rows or a plurality of columns) according to a gradient sorting manner, specifically referring to the following embodiments:
[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, which is a schematic flow chart of a display screen ash drop detection method according to a first embodiment of the present invention, the display screen ash drop detection method includes:
step S1, acquiring a gradient color channel, a gradient level and a stretching amount;
step S3, obtaining a plurality of basic color data according to the gradient color channel and the gradient progression;
step S5, generating a gradient picture according to a gradient sorting mode, the stretching amount, and the plurality of basic color data, wherein the number of pixels of a color corresponding to each basic color data in the gradient picture that are continuously filled in the gradient sorting mode is equal to the stretching amount; and
and step S7, sending the gradually changed picture to a target display screen for displaying.
The color corresponding to the gradient color channel may be red, green, blue, white, yellow, cyan, or purple. For example, red for the red channel, green for the green channel, cyan for the green channel and blue channel. For example, the color may be represented as (R, G, B), where R is the grayscale value for the red channel, G is the grayscale value for the green channel, and B is the grayscale value for the blue channel, e.g., red is represented as (255,0,0), blue is represented as (0, 255), and cyan is represented as (0,255,255); of course, the color data may also include transparency data for representing transparency information of the color. The progression may be a 32-level, 64-level, 128-level, or 256-level progression. The stretching amount may be any positive integer such as 1, 5, 6, 10 or 20, and is not limited herein.
The gradient sorting mode may be a horizontal gradient sorting mode or a vertical gradient sorting mode, where the horizontal gradient sorting mode is to display colors corresponding to the basic colors in columns, for example, to display colors corresponding to the basic colors horizontally in columns from left to right, and the vertical gradient sorting mode is to display colors corresponding to the basic colors in rows, for example, to display colors vertically in rows from top to bottom. The gradation color channel, the gradation level and the stretching amount may be obtained in response to a user operation instruction, may be obtained in other manners, and may also be obtained in response to a user operation instruction.
The number of the plurality of basic color data is the same as the number of gradation levels, for example, the number of gradation levels is 64, and there are 64 corresponding basic color data; for example, if the color corresponding to the gradation color channel is red and is represented as (255,0,0), it is necessary to extract 64 red grayscale values from the red grayscale values 0 to 255 as grayscale values of 64 basic color data, for example, the grayscale values of the gradation color channels of the plurality of basic color data are arranged in an arithmetic progression with the tolerance of 4, where the 64 basic color data are (0,0,0), (4,0,0), (8,0,0) … … (252,0,0) starting from 0 and the grayscale values of the red grayscale values of the gradation color channel of the plurality of basic color data are (0,0, 0).
The stretching amount is the number of continuous pixels of each color corresponding to the basic color data displayed in the gradient picture according to the gradient sorting mode, that is, the number of continuous display rows or continuous display columns of each color corresponding to the basic color data in the gradient picture; specifically, when the gradient sorting mode is horizontal gradient sorting, the number of rows of colors corresponding to one piece of basic color data continuously displayed in the gradient picture changes with the size of the stretching amount; or when the gradient sorting mode is vertical gradient sorting, the line number of the color corresponding to one piece of basic color data continuously displayed in the gradient picture changes along with the stretching amount.
In one embodiment, the step S2 may further include: uniformly selecting a plurality of gray values with the number equal to the gradient progression in the gray value range of the gradient color channel as the gray values of the color channels of the plurality of basic color data respectively; the gradation value arithmetic sequence of the color channels of the plurality of pieces of basic color data is, for example, an arithmetic sequence starting from 0.
Wherein, the plurality of basic color data may be calculated by using a formula a ═ B ÷ C × C', where a is a gray value of a selected color channel in the basic color data, B is a maximum value of gray values of a color channel corresponding to the gradation color, and C is a gradation number; for example, the gradation level number C is 64 levels, the gradation color is green, and is expressed as (0,255,0), for example, and the color data B is 255 corresponding to the green data G in RGB, and when C ' is 0, the first base color data is obtained as (0,0,0), and when C ' is 1, the second base color data is obtained as (0,4,0), and so on until C ' is 63, the last base color data is obtained as (0,252,0), and 64 base color data are obtained.
The gradation color is yellow, for example, represented as (255,255,0), the color data B is 255 corresponding to the red data R and 255 corresponding to the green data G in RGB, when the gradation number is 128 levels, when C ' is 0, the first base color data is (0,0,0), when C ' is 1, the second base color data is (2,2,0), and so on until C ' is 127, the last base color data is (254,254,0), and 128 pieces of base color data are obtained.
In one embodiment, the step S5 may further include: and filling the colors corresponding to the plurality of basic color data one by one according to a gradient direction in the gradient sorting mode, wherein the number of continuous pixels filled by the plurality of colors corresponding to the plurality of basic color data respectively is the same, and the gradient picture is generated.
Further, the gradient sorting mode comprises horizontal gradient sorting or vertical gradient sorting; the gradation direction includes a forward gradation in which the plurality of base color data are arranged with gradation values increasing from a minimum value, for example, increasing from 0, or a reverse gradation in which the plurality of base color data are arranged with gradation values decreasing from a maximum value.
The gradual change direction can be a default direction, which can be a forward gradual change or a reverse gradual change, and can also be obtained in response to a user operation instruction.
When the gradient sorting mode is horizontal gradient sorting and the gradient direction is forward gradient, the 1 st to 10 th columns of pixels for displaying the color corresponding to the basic color data (0,0,0) are determined according to the stretching amount 10, then the 11 th to 20 th columns of pixels for displaying the color corresponding to the basic color data (2,2,0) are determined according to the stretching amount 10, and the like until the 1271 th and 1280 th columns of pixels of the color corresponding to the basic color data (254, 0) are displayed according to the stretching amount 10, so that the gradient picture is obtained.
When the gradient sorting mode is vertical gradient sorting and the gradient direction is reverse gradient, determining the pixels in the 1 st to 10 th columns for displaying the corresponding colors of the basic color data (254, 0) according to the stretching amount 10, then determining the pixels in the 11 th to 20 th columns for displaying the corresponding colors of the basic color data (252, 0) according to the stretching amount 10, and so on until the pixels in the 1271 st and 1280 th columns for displaying the corresponding colors of the basic color data (0,0,0) according to the stretching amount 10, thereby obtaining the gradient picture.
Referring to fig. 2, in one embodiment, the step S7 includes, for example:
step S71, acquiring a target display area on the target display screen;
step S73, displaying the gradient picture in the target display area of the target display screen.
In step S71, the target display area may be obtained in response to a user operation, or may be a whole area or a partial area on the display screen, where the target display area includes position information and size information, the position information may be an offset of a starting point of the target display area with respect to a starting point of the target display screen, and the size information may be a width and a height of the target display area.
The method comprises the steps that a gradient picture is displayed in a target display area of a target display screen, the gradient picture can be displayed on the top layer, namely, a layer where the gradient picture is located is always located on the uppermost layer and cannot be shielded.
For a better understanding of the embodiments of the present invention, the following detailed description of the embodiments of the present invention is provided:
responding to user operation to obtain that the color corresponding to the gradient color channel is red, the gradient level is 32, the stretching amount is 10, the gradient sequencing mode is horizontal gradient sequencing and the gradient direction is forward gradient; furthermore, a target display area on the target display screen is obtained in response to the user operation.
In view of the above, referring to fig. 3, which is a schematic structural diagram of a display of a gradient picture on a target display screen in an embodiment of the present invention, where the target display screen 100 may be an LED display screen, and a target display area 110 in the LED display screen is used for displaying the gradient picture generated in the embodiment of the present invention to perform gray jump detection on the target display screen 100, where an offset of a starting position 111 of the target display area with respect to a starting position 120 of the target display screen, a width W of the target display area 110, and a height H are obtained in response to a user operation, so as to determine the target display area 110 on the target display screen 100.
Further, 32 corresponding basic color data are obtained according to the gradient color channel and the gradient progression, which are respectively: (0,0,0), (8,0,0), (16,0,0) … … (240,0,0), (248,0, 0).
Further, the pixels in the 1 st to 10 th columns in the target display area 110 are rendered as the color corresponding to (0,0,0), the pixels in the 11 th to 20 th columns in the target display area 110 are rendered as the color corresponding to (8,0,0), until the pixels in the 311 st and 320 th columns are rendered as the color corresponding to (248,0,0), when the width of the target display area 110 is larger than 320, the pixels in the 321 st and 330 th columns in the target display area 110 are rendered continuously from the color corresponding to (0,0,0) until the target display area 110 is fully rendered; if the width of the target display area 110 is smaller than 320, all basic color data may not be used for the purpose of drawing the target display area 110.
Further, the gradually-changed picture 110 can be dynamically displayed in the display area, for example, the moving direction and the moving speed of the gradually-changed picture are determined in response to the user operation instruction, so that the gradually-changed picture 110 is dynamically displayed in the display area to realize the display effect similar to a ticker.
In summary, in the embodiment of the present invention, one basic color data is displayed in multiple rows or multiple columns (determined according to the stretching amount) corresponding to the color according to the gradient sorting manner, so that when one color is displayed in multiple rows or multiple columns, if a gray skipping problem occurs in the multiple rows or multiple columns of pixel points, a detection person can easily recognize the color by naked eyes, thereby improving the accuracy of the gray skipping detection of the display screen.
