On the basis of the above embodiments, the present embodiment further describes and optimizes the technical solution.
In the display panel pixel arrangement in which adjacent pixels share a subpixel, the subpixel sharing pattern is regular. According to the common sub-pixel mode of adjacent pixels of the pixel arrangement of the existing market mainstream OLED (Organic Light-Emitting Diode), the pixel arrangement mode of the display screen can be divided into two main categories: adjacent pixel sub-pixels are shared vertically, such as an RGB-Delta pixel arrangement, and adjacent pixel sub-pixels are shared vertically, such as an RGB-Pentile pixel arrangement. Moreover, because the pixel arrangement mode of the common sub-pixels is adopted, in order to avoid the situation of color cast during the display of the display screen, color trimming needs to be performed for different pixel arrangement modes, and the correction modes corresponding to different pixel arrangement modes are different. The embodiment of the invention judges the pixel arrangement mode of the display screen to be tested by presetting a regular test image and displaying the test image by using the display screen to be tested by using different correction methods for different sub-pixel sharing modes, and comparing a standard display result according to the color difference of color blocks when the display screen to be tested displays the test image.
Specifically, in this embodiment, the test image includes two stripe images disposed side by side or in parallel; wherein, one of the two stripe images is a black-and-white alternate horizontal stripe image, the other is a black-and-white alternate vertical stripe image, and the height of a single horizontal stripe or the width of a vertical stripe is a pixel;

and determining the pixel arrangement mode of the display screen to be detected by comparing the color block chromatism of the display color of the display screen to be detected and combining the placing direction of the display screen to be detected.
A schematic diagram of a test image provided in connection with the embodiment of the invention shown in fig. 3a and 3 b; fig. 3a shows a stripe image in a parallel arrangement, and fig. 3b shows a stripe image in a parallel arrangement. In this embodiment, the test image comprises two fringe images placed side-by-side or side-by-side; wherein, the parallel arrangement means that the two stripe images are on the same horizontal line, and the parallel arrangement means that the two stripe images are on the same vertical axis.
Specifically, black and white alternation means that the black stripes and the white stripes are mutually spaced, namely, the white stripes are used for spacing two adjacent black stripes, and the black stripes are used for spacing two adjacent white stripes; the black-white alternate horizontal stripe image refers to that black stripes and white stripes in the black-white alternate stripe image extend in a horizontal line shape along the horizontal direction, and the black-white alternate vertical stripe image refers to that black stripes and white stripes in the black-white alternate stripe image extend in a vertical line shape along the vertical direction. In addition, in this embodiment, the height of a single horizontal stripe or the width of a vertical stripe is one pixel, and the pixels of the black and white stripe in the stripe image are the same as the pixels of the display screen to be measured.
It should be noted that, based on the form of the test image set in the embodiment of the present invention, when the display screen to be tested is used to display the test image, the display color of the display screen to be tested is caused to have a color cast condition, that is, the display color of the display screen to be tested has a color block and color difference condition.
In addition, the placing directions of the display screen to be tested comprise horizontal placing and vertical placing, wherein the horizontal placing means that the length of the display screen to be tested is placed along the horizontal direction, and the width of the display screen to be tested is placed along the vertical direction; the vertical placement means that the length of the display screen to be tested is placed along the vertical direction, and the width of the display screen to be tested is placed along the horizontal direction. And determining the pixel arrangement mode of the display screen to be detected according to different placement directions of the display screen to be detected and the combination of color block chromatism of the display color of the display screen to be detected.
Therefore, according to the method of the embodiment, the pixel arrangement mode of the display screen to be detected can be conveniently and accurately determined.
As a preferred embodiment, when the stripe images in the test image are placed side by side and the display screen to be tested is placed vertically, determining the pixel arrangement mode of the display screen to be tested according to the display color of the display screen to be tested includes:
when the black-white interphase vertical stripe image is displayed greenish compared with the black-white interphase horizontal stripe image, determining that the pixel arrangement mode of the display screen to be tested is the horizontal sharing of the sub-pixels of the adjacent pixels;
and when the black-white interphase horizontal stripe image is displayed greenish compared with the black-white interphase vertical stripe image, determining that the pixel arrangement mode of the display screen to be tested is longitudinally shared by adjacent pixel sub-pixels.
In addition, when the stripe images in the test image are placed side by side and the display screen to be tested is placed transversely, the pixel arrangement mode for determining the display screen to be tested according to the display color of the display screen to be tested comprises the following steps:
when the black-white interphase vertical stripe image is displayed greenish compared with the black-white interphase horizontal stripe image, determining that the pixel arrangement mode of the display screen to be tested is longitudinally shared by adjacent pixel sub-pixels;
and when the black-white interphase horizontal stripe image is displayed greenish compared with the black-white interphase vertical stripe image, determining that the pixel arrangement mode of the display screen to be tested is the horizontal sharing of the sub-pixels of the adjacent pixels.
Specifically, when the stripe images in the test image are placed side by side, the black-and-white alternate vertical stripe image may be on the left side of the black-and-white alternate horizontal stripe image, or the black-and-white alternate vertical stripe image may be on the right side of the black-and-white alternate horizontal stripe image, which is not limited in this embodiment.
It should be noted that when the stripe images in the test image are placed side by side and the display screen to be tested is placed vertically, if the pixel arrangement mode of the display screen to be tested is that the sub-pixels of the adjacent pixels are shared horizontally, the black-and-white alternate vertical stripe image just attenuates the brightness of the blue and green shared sub-pixels, so that the display screen to be tested can have the condition that the display color is greenish when the black-and-white alternate vertical stripe image is displayed; and the horizontal pixels are closed in the black and white alternate horizontal stripe image, so that the pixels sharing the sub-pixels cannot be damaged, the color cast condition cannot be caused, and the display is normal. When the pixel arrangement mode of the display screen to be tested is that adjacent pixel sub-pixels are longitudinally shared, the situation is just opposite, the display screen to be tested displays normal images when black and white alternate vertical stripe images are displayed, and the display color is greenish when black and white alternate horizontal stripe images are displayed.
More specifically, for example, when the black-and-white vertical stripe image is set on the left side of the test image, the black-and-white horizontal stripe image is set on the right side of the test image, and the display screen to be tested is vertically placed, if the test image on the left side is displayed greenish compared with the test image on the right side, it is determined that the pixel arrangement mode of the display screen to be tested is horizontal sharing of the adjacent pixel sub-pixels, otherwise, it is determined that the pixel arrangement mode of the display screen to be tested is vertical sharing of the adjacent pixel sub-pixels; when the black-and-white alternate vertical stripe image is arranged on the left side of the test image, the black-and-white alternate horizontal stripe image is arranged on the right side of the test image, and the display screen to be tested is transversely arranged, if the test image on the left side is displayed greenish compared with the test image on the right side, the pixel arrangement mode of the display screen to be tested is determined to be the longitudinal sharing of the adjacent pixel sub-pixels, otherwise, the pixel arrangement mode of the display screen to be tested is determined to be the transverse sharing of the adjacent pixel sub-pixels.
As another preferred embodiment, when the stripe images in the test image are placed side by side and the display screen to be tested is placed vertically, determining the pixel arrangement mode of the display screen to be tested according to the display color of the display screen to be tested includes:
when the black-white interphase vertical stripe image is displayed greenish compared with the black-white interphase horizontal stripe image, determining that the pixel arrangement mode of the display screen to be tested is the horizontal sharing of the sub-pixels of the adjacent pixels;
and when the black-white interphase horizontal stripe image is displayed greenish compared with the black-white interphase vertical stripe image, determining that the pixel arrangement mode of the display screen to be tested is longitudinally shared by adjacent pixel sub-pixels.
In addition, when the stripe images in the test image are placed in parallel and the display screen to be tested is placed transversely, the pixel arrangement mode for determining the display screen to be tested according to the display color of the display screen to be tested comprises the following steps:
when the black-white interphase vertical stripe image is displayed greenish compared with the black-white interphase horizontal stripe image, determining that the pixel arrangement mode of the display screen to be tested is longitudinally shared by adjacent pixel sub-pixels;
and when the black-white interphase horizontal stripe image is displayed greenish compared with the black-white interphase vertical stripe image, determining that the pixel arrangement mode of the display screen to be tested is the horizontal sharing of the sub-pixels of the adjacent pixels.
Specifically, when the stripe images in the test image are placed side by side, the black-and-white interphase vertical stripe image may be located on the upper side of the black-and-white interphase horizontal stripe image, or the black-and-white interphase vertical stripe image may be located on the lower side of the black-and-white interphase horizontal stripe image, which is not limited in this embodiment.
It should be noted that, when the stripe images in the test image are placed in parallel and the display screen to be tested is placed vertically, if the pixel arrangement mode of the display screen to be tested is that the sub-pixels of the adjacent pixels are shared horizontally, the black-and-white alternate vertical stripe image just attenuates the brightness of the blue and green shared sub-pixels, so that the display screen to be tested has a greenish display color when displaying the black-and-white alternate vertical stripe image; and the horizontal pixels are closed in the black and white alternate horizontal stripe image, so that the pixels sharing the sub-pixels cannot be damaged, the color cast condition cannot be caused, and the display is normal. When the pixel arrangement mode of the display screen to be tested is that adjacent pixel sub-pixels are longitudinally shared, the situation is just opposite, the display screen to be tested displays normal images when black and white alternate vertical stripe images are displayed, and the display color is greenish when black and white alternate horizontal stripe images are displayed.
More specifically, for example, when the black-and-white vertical stripe image is set on the upper side of the test image, the black-and-white horizontal stripe image is set on the lower side of the test image, and the display screen to be tested is vertically placed, if the upper test image is displayed greenish compared with the lower test image, it is determined that the pixel arrangement mode of the display screen to be tested is horizontal sharing of the adjacent pixel sub-pixels, otherwise, it is determined that the pixel arrangement mode of the display screen to be tested is vertical sharing of the adjacent pixel sub-pixels; when the black-white alternating vertical stripe image is arranged on the upper side of the test image, the black-white alternating horizontal stripe image is arranged on the lower side of the test image, and the display screen to be tested is transversely arranged, if the upper test image is relatively greenish compared with the lower test image, the pixel arrangement mode of the display screen to be tested is determined to be longitudinally shared by adjacent pixel sub-pixels, otherwise, the pixel arrangement mode of the display screen to be tested is determined to be transversely shared by the adjacent pixel sub-pixels.
Therefore, according to the method of the embodiment, the pixel arrangement mode of the display screen to be detected can be conveniently and accurately determined by comparing the color deviation condition of the color block color difference of the black-white alternate horizontal stripe image and the black-white alternate vertical stripe image and combining the placing direction of the display screen to be detected.
As a preferred embodiment, the method further comprises:
and if the color cast phenomenon does not occur in the black-white alternate horizontal stripe image and the black-white alternate vertical stripe image, determining that the pixel arrangement mode of the display screen to be detected is single-pixel independent arrangement or non-shared sub-pixel arrangement.
Specifically, in actual operation, if the horizontal stripe image between black and white phases and the vertical stripe image between black and white phases are not color-shifted regardless of whether the stripe images in the test image are placed side by side or side by side, that is, after the horizontal stripe image between black and white phases and the vertical stripe image between black and white phases are displayed on the display screen to be tested, the display color is normally displayed as gray, it is determined that the display screen to be tested does not adopt a pixel-shared arrangement mode, and the pixel arrangement mode of the display screen to be tested is a single-pixel independent arrangement or a non-shared sub-pixel arrangement.
Therefore, according to the method of the embodiment, the pixel arrangement mode of the display screen to be detected can be further determined to be a single-pixel independent arrangement mode or a non-shared sub-pixel arrangement mode, and the pixel arrangement mode of the display screen to be detected can be comprehensively detected.
On the basis of the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and specifically, in this embodiment, after the display screen to be tested is used to display a test image, and the pixel arrangement mode of the display screen to be tested is determined according to the display color of the display screen to be tested, the method further includes:
and determining the display screen type corresponding to the display screen to be tested according to the corresponding relation between the preset pixel arrangement mode and the display screen type.
It should be noted that, in this embodiment, a corresponding relationship between the pixel arrangement mode and the Display screen type needs to be preset, for example, when the pixel arrangement mode is a single-pixel independent arrangement or a non-shared sub-pixel arrangement, the corresponding Display screen type may be a TFT (Thin Film Transistor) Display screen or an LCD (Liquid Crystal Display); the TFT display screen consists of liquid crystal pixel points and is driven by a thin film transistor integrated behind the pixel points; the LCD display screen is constructed by placing liquid crystal boxes between two parallel glass substrates, arranging TFT (thin film transistor) on the lower substrate glass, arranging color filter on the upper substrate glass, and controlling the rotation direction of liquid crystal molecules by changing the signal and voltage on the TFT, so as to control whether polarized light of each pixel point is emitted or not to achieve the display purpose.
When the pixel arrangement is that the adjacent pixel sub-pixels are shared horizontally or the adjacent pixel sub-pixels are shared vertically, the corresponding display screen type may be an OLED (Organic Light-Emitting Diode) display screen or a Super AMOLED (Super Active Matrix/Organic Light Emitting Diode) display screen.
More specifically, the display screen type corresponding to the horizontal sharing of the adjacent pixel sub-pixels is an RGB-Delta pixel arrangement display screen, and the display screen type corresponding to the vertical sharing of the adjacent pixel sub-pixels is an RGB-Pentile pixel arrangement display screen. As shown in fig. 4a to 4c, in the RGB-Delta pixel arrangement, fig. 4a is a pixel arrangement pattern of a single pixel, fig. 4b is a horizontal adjacent blue and red sub-pixel sharing arrangement pattern, and fig. 4c is a vertical adjacent pixel arrangement pattern. As shown in fig. 5a to 5c, in the RGB-Pentile pixel arrangement, fig. 5a shows a pixel arrangement pattern of a single pixel, fig. 5b shows a vertical adjacent blue and red sub-pixel sharing arrangement pattern, and fig. 5c shows a vertical adjacent pixel arrangement pattern.
In actual operation, after the pixel arrangement mode of the display screen to be detected is determined, the display screen type of the display screen to be detected is determined according to the corresponding relation between the preset pixel arrangement mode and the display screen type.
It is thus clear that this embodiment can further determine the display screen type that corresponds with the display screen that awaits measuring after determining the pixel arrangement with the display screen that awaits measuring through the further corresponding relation of predetermined pixel arrangement and display screen type, can be convenient for the user obtain more information of the display screen that awaits measuring directly perceivedly to further promote user's use experience.
On the basis of the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and specifically, in this embodiment, after the display screen to be tested is used to display a test image, and the pixel arrangement mode of the display screen to be tested is determined according to the display color of the display screen to be tested, the method further includes:
acquiring a pixel arrangement mode and corresponding test time;
and correspondingly storing the pixel arrangement mode and the test time.
Specifically, in this embodiment, after the pixel arrangement mode of the display screen to be tested is determined, the test time for determining the pixel arrangement mode of the display screen to be tested is further obtained, that is, the pixel arrangement mode and the corresponding test time are obtained; and then correspondingly storing the acquired pixel arrangement mode and the test time.
It should be noted that, a specific storage manner may be recorded in a form of text or a table, and the recorded information is stored in a Memory bank, a hard disk, a TF (Trans-flash Card) Card or an sd (secure Digital Memory Card) Card, which is specifically selected according to actual requirements, and this embodiment is not limited thereto.
In addition, the pixel arrangement mode and the test time can be written into a log file correspondingly; the log file is a record file or a file set for recording system operations, and has functions of processing history data, tracing diagnostic problems, and the like.
Therefore, the pixel arrangement mode and the test time of the display screen to be tested are further correspondingly stored, so that the test information can be conveniently inquired subsequently, and the use experience of a user is further improved.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
