FIG. 2 schematically shows a schematic diagram of tool options of an image editor according to an embodiment of the invention. As shown in fig. 2, the processor controls the image editor to display tool options. The user can select a 'pixel image' option from tool options on an interface of an image editor, click and drag the "pixel image" option in a drawing area to a certain size to form an image block, wherein the size of the image block is an integral multiple of the minimum grid of the background unit.
Fig. 3 schematically shows a schematic view of a preliminary display of an image editor according to an embodiment of the invention. As shown in fig. 3, the interface of the image editor is automatically changed to the interface shown in fig. 3 in response to the user's operation. Specifically, the processor displays all pixels of the repeating unit of the image block in a row-column arrangement, and each pixel is displayed in units of sub-pixels. For example, in fig. 3, 3 sub-pixels are used as one pixel, the number of column pixels in the repeating unit of the image block is 3, and the number of row pixels is 2.
In one example, a user may input the number of row pixels and the number of column pixels of a repeating unit of an image block at an interface of an image editor. The processor may receive an input number of row pixels and a number of column pixels of a repeating unit of an image block; all pixels of the repeating unit are displayed in a row and column arrangement according to the number of row pixels and the number of column pixels, and each pixel is displayed in a sub-pixel unit. As shown in fig. 3, if the number of column pixels and the number of row pixels of the repeating unit of the image block obtained by the processor are 3 and 2, all pixels of the repeating unit are displayed according to the number of column pixels and the number of row pixels being 3 and the number of row pixels being 2, that is, the repeating unit is displayed as an array of 2 rows and 9 sub-pixels. Fig. 4 schematically shows a schematic view of a preliminary display of an image editor according to another embodiment of the invention. As shown in fig. 4, if the number of column pixels of the repeating unit of the image block obtained by the processor is 4 and the number of row pixels is 3, all the pixels of the repeating unit of the image block are displayed according to the number of column pixels of 4 and the number of row pixels of 3, and each pixel has 3 sub-pixels, that is, the repeating unit is displayed as an array of 3 rows and 12 sub-pixels.
In another example, the user may select an option of color order at the interface of the image editor, and the processor receives the order of sub-pixels input by the user, and displays each pixel in sub-pixel units and according to the sub-pixel order, where the order of sub-pixels is the order of color components. For example, the sequence of the sub-pixels in fig. 3 is BGR, and accordingly, the sequence of the sub-pixels displaying each pixel in the display area of the repeating unit is BGR; as another example, the input sequence of sub-pixels is RBG as shown in fig. 5, and accordingly, the sequence of sub-pixels displaying each pixel in the display area of the repeating unit also becomes RBG. Therefore, a user can generate a suitable test image according to the sequence of the sub-pixels of the display module to be tested, and the requirements of the user can be met.

And after receiving the information, the processor edits and responds to the image block, and displays the image block at the corresponding position of the background grid. Embodiments of the invention can take advantage of this functionality to make multiple different image blocks. For example, an image block of a left half screen, an image block of a right half screen; an image block of the first preset background grid, an image block of the second preset background grid … …; or in a special scene (the display module to be tested controls the display through a plurality of same control units), the requirements for setting the lower band of each image block correspond to the pixel width and the pixel height which can be controlled by the minimum control unit to be displayed, and the like.
In yet another example, the processor may position the image block on a grid line closest to the target location in response to the first operation of dragging and dropping the image block to the target location. Specifically, the user may drag and drop the image block to the target position, but this first operation is not necessarily able to position the image block on the grid line. Therefore, the processor can adsorb and fix the image block on the grid line closest to the release position, so that quick positioning can be realized.
