In an embodiment, the visible area 101 may also be used to implement other functions, such as an area for receiving a touch sensing operation in a display device having a touch sensing function. In an embodiment, the visible area 101 can be used as an area for displaying a display screen of the display panel 2 and an area for receiving a touch sensing operation in a display device having both a display function and a touch sensing function.
As shown in fig. 2, in the present embodiment, both the first ink layer 3 and the second ink layer 4 are ring-shaped. The outer edges of the first and second ink layers 3, 4 remote from the viewing area 101 are aligned and the outer edges near the viewing area 101 are misaligned. The coverage area of the second ink layer 4 on the cover plate 1 is smaller than that of the first ink layer 3.

The number of the ink layers is not limited, and only one ink layer or more than three ink layers may be printed on the peripheral region 102 of the cover plate 1 according to actual needs.
Referring to fig. 4, fig. 4 is a schematic plan view of a display panel 2 according to an embodiment of the invention, in order to clearly show a positional relationship between a cover plate 1 and the display panel 2, fig. 4 shows an outer edge of a first ink layer 3 near a visible area 101 and an opening 31 by a dotted line, in this embodiment, the display panel 2 is an organic light emitting electroluminescent (O L ED) display panel, the display panel 2 defines a pixel array 7, and the pixel array 7 includes a plurality of sub-pixels, in this embodiment, the pixel array 7 defines a plurality of first sub-pixels 71, second sub-pixels 72, and third sub-pixels 73 arranged in an array, and the sub-pixels are disposed not only in the visible area 101 but also in a peripheral area 102.
In the present embodiment, the first sub-pixel 71 is a blue sub-pixel (B), the second sub-pixel 72 is a red sub-pixel (R), and the third sub-pixel 73 is a green sub-pixel (G). The first sub-pixels 71 are arranged in a first direction (X direction in the drawing) to form a plurality of rows, and arranged in a second direction (Y direction in the drawing) to form a plurality of columns, the first direction intersecting the second direction, and in the present embodiment, the first direction and the second direction are orthogonal. The second sub-pixels 72 are arranged in the X direction in the figure to form a plurality of rows, and in the Y direction in the figure to form a plurality of columns. The third sub-pixels 73 are arranged in the X direction in the figure to form a plurality of rows, and in the Y direction in the figure to form a plurality of columns.
The first and second sub-pixels 71 and 72 are alternately arranged in the same column. Between every two adjacent columns arranged with the first sub-pixel 71 and the second sub-pixel 72, there is one column arranged with the third sub-pixel 73. Each adjacent one of the first sub-pixel 71, one of the second sub-pixels 72, and one of the third sub-pixels 73 constitutes one pixel unit of the display panel 2. In this embodiment, the pixel array 7 in fig. 4 is taken as an exemplary illustration, the arrangement of the pixel array 7 is not limited in the present invention, and the arrangement of the pixel array 7 is not limited to the arrangement shown in fig. 4, and may be other arrangements, which are not listed here.
As shown in fig. 4, the display panel 2 shown in fig. 4 is aligned with the cover plate 1 in an assembled position. In actual alignment assembly, there may be a certain alignment tolerance in the positional relationship between the display panel 2 and the cover plate 1. In the pixel array 7, at least one sub-pixel located in the peripheral region 102 and overlapping with the first ink layer 3 is defined as an alignment pixel 701. Defining a designated point in the display panel 2 as a rotation center (e.g. a center point thereof), the allowable deflection angle of the display panel 2 is smaller than θ in a direction parallel to the cover plate 1 compared to the cover plate 1.
As shown in fig. 4, when the alignment pixel 701 is located right in the middle of the corresponding first opening 311 and second opening 312, the deflection angle is 0. After the display panel 2 is rotated counterclockwise by θ degrees in a direction parallel to the cover 1, the first opening 311 overlaps the rotated position of the alignment pixel 701 in the direction of the cover 1, and after the display panel 2 is rotated clockwise by θ degrees in a direction parallel to the cover 1, the second opening 312 overlaps the rotated position of the alignment pixel 701 in the direction of the cover 1.
In the embodiment, when the alignment pixel 701 and the opening 31 are used for assembling the display device 100, it is determined whether the display panel 2 and the cover plate 1 are aligned accurately, and when the alignment pixel 701 and the opening 31 are not overlapped, the display panel 2 and the cover plate 1 are aligned accurately; when the alignment pixel 701 overlaps the opening 31, the alignment of the display panel 2 and the cover plate 1 is not accurate.
In the present embodiment, a row in which the first sub-pixels 71 are arranged in the middle of the row arranged in the X direction in fig. 4 is defined as a pair pixel row; the middle one of the columns arranged along the Y direction in fig. 4 in which the first sub-pixels 71 are arranged is taken as a pair of pixel columns, and a pair of pixel rows 703 and a pair of pixel columns 704 intersect. In one embodiment, any one of the rows arranged along the X-axis direction in fig. 4 may be defined as the alignment pixel row 703; any one of the columns arranged in the Y direction in fig. 4 is taken as a pair-pixel column 704. In the embodiment, the display panel 2 is circular, and the intersection point of the alignment pixel row 703 and the alignment pixel column 704 is the center of the display panel 2.
In the embodiment, the alignment pixel row 703 includes at least one first sub-pixel 71 covered by the first ink layer 3 after the display panel 2 is attached to the cover plate 1, and is defined as an alignment pixel 701; the alignment pixel row 704 includes at least one first sub-pixel 71 covered by the first ink layer 3 after the display panel 2 is attached to the cover plate 1, and is defined as an alignment pixel 701. The alignment pixel 701 at least partially overlaps the first ink layer 3 in a direction perpendicular to the cover plate 1.
In the present embodiment, each alignment pixel row includes two alignment pixels 701 respectively located at two ends of the alignment pixel row, each alignment pixel column includes two alignment pixels 701 respectively located at two ends of the alignment pixel column, and each alignment pixel 701 corresponds to one set of openings 31. But is not limited thereto, and the number of the bit pixels is not limited. In other embodiments, the display panel 2 may have only one alignment pixel 701.
Referring to fig. 3 and fig. 4, it is defined that the allowable deflection angle of the alignment pixel 701 with the center of the circle of the display panel 2 as the rotation center is smaller than θ in the process of assembling the display panel 2 and the cover plate 1. The alignment pixel 701 is rotated counterclockwise by θ degrees with the center of the display panel 2 as the rotation center, and overlaps the first opening 311 in the direction of the cover 1. The alignment pixel 701 is rotated clockwise by θ degrees around the center of the display panel 2 as the rotation center, and overlaps the second opening 312 in the direction of the cover 1. In the present embodiment, θ is 1 °. In one embodiment, 0 < θ < 2. In other embodiments, 0 ° < θ < 30 °.
In the present embodiment, the fluorescent ink 5 is a material that emits light when excited by blue light. Referring to fig. 5 and fig. 6, after the cover plate 1 and the display panel 2 are aligned and assembled, when the alignment pixel 701 and the first opening 311 are overlapped in the direction of the cover plate 1, the light emitted from the alignment pixel 701 excites the fluorescent ink 5 filled in the first opening 311, so that the fluorescent ink 5 emits light. Since blue light has a shorter wavelength and a higher energy than red light or green light, in the present embodiment, the fluorescent ink 5 can be excited only by blue light and is not excited by the second sub-pixel 72 emitting red light or the third sub-pixel 73 emitting green light. In other embodiments, the second sub-pixel 72 can be defined as an alignment pixel, and a material excited by red light is used as the fluorescent ink 5; or the third sub-pixel 73 is defined as a counter pixel and a material excited by green light is used as the fluorescent ink 5.
In the manufacturing process of the display device 100, when the cover plate 1 and the display panel 2 are assembled in alignment, there may be an alignment error between the cover plate 1 and the display panel 2. After the cover plate 1 and the display panel 2 are aligned and assembled, it is necessary to determine whether the deflection angle between the cover plate 1 and the display panel 2 due to the alignment error meets the specification.
When the deflection angle between the cover plate 1 and the display panel 2 is less than θ, the display device 100 is in accordance with the assembly specification. When the deviation angle between the cover plate 1 and the display panel 2 is larger than θ, the display device 100 is not in compliance with the assembly specification. In one embodiment, when the deviation angle between the cover 1 and the display panel 2 is not greater than θ, the first sub-pixels 71 in the alignment pixel rows 703 and the alignment pixel columns 704 are turned on to determine whether the fluorescent ink 5 emits light.
As shown in fig. 5 and 6, when the fluorescent ink 5 emits light, the alignment pixel 701 overlaps the projection of the opening 31 in the direction of the cover plate 1, and the deflection angle between the cover plate 1 and the display panel 2 is θ; as shown in fig. 2 and 4, if the fluorescent ink 5 does not emit light, the alignment pixel 701 is located between the corresponding first opening 311 and second opening 312, and the deflection angle between the cover plate 1 and the display panel 2 is smaller than θ.
For a display device 100 with a deflection angle between the cover plate 1 and the display panel 2 smaller than θ, the fluorescent ink 5 is not excited by the light emitted by the first sub-pixel 71, since the projection of the opening 31 and the first sub-pixel 71 in the direction of the cover plate 1 do not overlap.
In other embodiments, the opening 31 may not be filled with the fluorescent ink 5, and may be directly hollowed out or filled with other light-transmitting materials. When the light emitted from the alignment pixel 701 passes through the opening 31, the alignment pixel 701 overlaps with the projection of the opening 31 in the direction of the cover 1, and the deflection angle between the cover 1 and the display panel 2 is θ. When the light emitted from the alignment pixel 701 does not pass through the opening 31, the alignment pixel 701 is located between the corresponding first opening 311 and the second opening 312, and the deflection angle between the cover plate 1 and the display panel 2 is smaller than θ.
In this embodiment, the alignment assembly between the cover plate 1 and the display panel 2 of the display device 100 is described as an example, but the present invention is not limited thereto, and in other embodiments, the alignment assembly between elements of other electronic devices may be performed.
In one embodiment, an electronic device may include a first element and a second element, the second element being stacked with the first element, the first ink layer partially covering one side of the first element; the first ink layer is provided with at least one group of openings, and each group of openings comprises a first opening and a second opening which penetrate through the first ink layer and are arranged at intervals; the opening can be filled with fluorescent ink, the second element is defined with at least one light-emitting unit which is overlapped with the first ink layer in the direction perpendicular to the first element, and when the light-emitting unit is overlapped with the opening in the direction perpendicular to the first element, the fluorescent ink in the opening can be excited to emit light, so that the position relation between the first element and the second element is judged.
Referring to fig. 7, fig. 7 is a flowchart illustrating an assembling method of a display device according to an embodiment of the invention. The assembling method of the display device of the embodiment of the invention comprises the following steps:
the method comprises the following steps: providing a transparent cover plate 1, arranging a first ink layer 3 on one side of the cover plate 1, and partially covering the cover plate 1 by the first ink layer 3; the first ink layer 3 is provided with at least one group of openings 31, and each group of openings 31 comprises a first opening 311 and a second opening 312 which are arranged at intervals;
step two: providing a display panel 2, wherein the display panel 2 has a plurality of sub-pixels, and the plurality of sub-pixels include at least one alignment pixel 701;
step three: assembling the display panel 2 and the cover plate 1 to enable the display panel 2 and the cover plate 1 to be arranged in a stacked mode;
step four: judging whether the deflection angle between the cover plate 1 and the display panel 2 is larger than theta, and when the deflection angle between the cover plate 1 and the display panel 2 is larger than theta, indicating that the cover plate and the display panel are not aligned accurately.
In the present embodiment, θ is 1 °.
When the deflection angle is not more than theta, the following steps are performed:
step five: the alignment pixel 701 of the display panel 2 is lit.
In this embodiment, the first sub-pixels 71 in the alignment pixel rows 703 and the alignment pixel columns 704 of the display panel 2 can be lit, thereby avoiding the difficulty in the operation of lighting the single alignment pixel 701.
Step six: it is determined whether light is emitted from the opening 31. When the alignment pixel and the opening are overlapped in the direction perpendicular to the cover plate, light is emitted from the opening 31, and the deflection angle between the cover plate 1 and the display panel 2 is theta, which indicates that the alignment between the cover plate and the display panel is not accurate; when the alignment pixel is located between a set of the first opening and the second opening, no light is emitted from the opening 31, and the deflection angle between the cover plate 1 and the display panel 2 is smaller than θ, which indicates that the cover plate and the display panel are aligned accurately.
In this embodiment, the fluorescent ink 5 may be disposed in the opening 31, and when the alignment pixel and the opening overlap in a direction perpendicular to the cover plate, the fluorescent ink emits light, which indicates that the cover plate and the display panel are not aligned accurately; when the alignment pixel is located between the first opening 311 and the second opening 312, the fluorescent ink does not emit light, which indicates that the cover plate and the display panel are aligned accurately.
As shown in fig. 5 and fig. 6, in the present embodiment, if the fluorescent ink emits light, it can be determined that the deflection angle between the cover plate 1 and the display panel 2 is θ, and the alignment between the display panel and the cover plate is not accurate;
as shown in fig. 3 and 4, in the present embodiment, if the fluorescent ink does not emit light, it can be determined that the deflection angle between the cover plate 1 and the display panel 2 is smaller than θ, and the alignment between the display panel and the cover plate is accurate.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
