Detailed Description

So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.

Referring to fig. 1A and 1B, an embodiment of the present disclosure provides a terminal connection structure including: a plurality of terminals 110, a plurality of terminal-side conductive holes 120, an electrical connection layer 130, and a plurality of light emitting device-side conductive holes 140; wherein the content of the first and second substances,

the electrical connection layer 130 can be electrically connected with the plurality of light emitting devices 150 in the light emitting device layer 1510 through the plurality of light emitting device side conductive holes 140, and electrically connected with the plurality of terminals 110 through the plurality of terminal side conductive holes 120;

the plurality of terminals 110 are arranged in an array and do not exceed the coverage of the light emitting device layer 1510.

Thus, even if the size of the light emitting device 150 is very small, the terminal 110 for wiring from the light emitting device 150 can be effectively provided. In addition, it is also advantageous to miniaturize the terminal connection structure.

In some embodiments, the electrical connection layer 130 may include at least two electrical connection layers; the at least two electrical connection layers can each be electrically connected to the plurality of light emitting devices 150 through the plurality of light emitting device side conductive holes 140, and each be electrically connected to the plurality of terminals 110 through the plurality of terminal side conductive holes 120.

Referring to fig. 1B, in some embodiments, the plurality of terminals 110 may not extend beyond a longitudinal projection range of the light emitting device layer 1510. In some embodiments, the coverage of the light emitting device layer 1510 may be expressed as a longitudinal projection of the light emitting device layer 1510. Alternatively, the light emitting device layer 1510 indicated by a dotted line frame may represent a longitudinal projection range of the light emitting device layer 1510.

As shown in fig. 1B, the longitudinal projection range of the light emitting device layer 1510 may be smaller than the coverage range of the electrical connection layer 130. In some embodiments, the longitudinal projection range of the light emitting device layer 1510 and the coverage range of the electrical connection layer 130 may be the same. Alternatively, the longitudinal projection range of the light emitting device layer 1510 may be larger than the coverage range of the electrical connection layer 130. Alternatively, the relationship between the coverage of the light emitting device layer 1510 and the coverage of the electrical connection layer 130 may be considered according to practical situations such as process requirements.

Referring to fig. 2, in some embodiments, the plurality of terminals 110 may not extend beyond a longitudinal projection of a plane 1520 defined by some or all of the light emitting devices 150 in the light emitting device layer 1510. In some embodiments, a longitudinal projection of a plane 1520 defined by portions of the light emitting devices 150 in the light emitting device layer 1510 is within the coverage of the light emitting device layer 1510. Alternatively, the longitudinal projection of the plane 1520 defined by all of the light emitting devices 150 in the light emitting device layer 1510 may be within the coverage of the light emitting device layer 1510, or may be the same as the coverage of the light emitting device layer 1510.

Referring to fig. 3, in some embodiments, at least one terminal 110 of the plurality of terminals 110 may be located at an edge of a coverage of the light emitting device layer 1510. As shown in fig. 3, the leftmost two terminals 110 are located at the left edge of the coverage of the light emitting device layer 1510, for example: the left edges of the leftmost two terminals 110 are aligned with the left edge of the coverage of the light emitting device layer 1510; the two rightmost terminals 110 are located at the right edge of the coverage of the light emitting device layer 1510, for example: right edges of the rightmost two terminals 110 are aligned with right edges of the coverage of the light emitting device layer 1510. Alternatively, for the terminals 110 located at the edge of the coverage of the light emitting device layer 1510, the number and positions of the terminals 110 may be considered according to practical situations such as process requirements.

In some embodiments, as can be seen in fig. 1B, none of the plurality of terminals 110 may be located at an edge of the coverage of the light emitting device layer 1510.

Referring to fig. 4, in some embodiments, a center a of the at least one terminal 110, which is located at an edge of the coverage of the light emitting device layer 1510, may not be aligned with a center B of the at least one terminal-side conductive hole 120 to which the at least one terminal 110 is connected. As shown in fig. 4, the rightmost terminal 110 is located at the edge of the coverage of the light emitting device layer 1510, and the center a (represented by a center line, which may also be referred to as an axis) of the terminal 110 is not on the same vertical straight line as the center B (represented by a center line, which may also be referred to as an axis) of the terminal-side conductive via 120 connecting the terminal 110.

In some embodiments, a center a of the at least one terminal 110, which is located at an edge of the coverage of the light emitting device layer 1510, may be aligned with a center B of the at least one terminal-side conductive hole 120 to which the at least one terminal 110 is connected. Alternatively, the center a of the at least one terminal 110, which is located within the coverage of the light emitting device layer 1510, may be aligned with the center B of the at least one terminal-side conductive hole 120 connected to the at least one terminal 110, or not. Alternatively, the alignment relationship between the center a of the terminal 110 and the center B of the terminal-side conductive hole 120 may be considered according to practical circumstances such as process requirements.

Referring to fig. 5, in some embodiments, at least one terminal 110, which is located at an edge of a coverage of the light emitting device layer 1510, may have a shape different from other portions or all of the terminals 110. In some embodiments, the shape of some or all of the terminals 110 in the plurality of terminals 110 may be the same or different. Alternatively, since the thickness of the terminal 110 is generally very small, the shape of the terminal 110 may refer to the shape of a longitudinal projection of the terminal 110. Optionally, at least one terminal 110 of the plurality of terminals 110 may have a rectangular shape, a circular shape, a spherical shape, or other shapes such as a polygonal shape and a special shape according to practical situations such as process requirements.

In some embodiments, at least one of the terminals 110, which is located at an edge of the coverage of the light emitting device layer 1510, may have an area different from other portions or all of the terminals 110. For example: as shown in fig. 5, the terminals 110 having a circular shape are located at the edge of the coverage of the light emitting device layer 1510, and the area of the circular terminals 110 may be smaller than the area of other portions or all of the terminals 110.

In some embodiments, regardless of whether the shape of some or all of the plurality of terminals 110 is the same, at least one terminal 110 of the plurality of terminals 110 may have an area different from other some or all of the terminals 110, such as: at least one terminal 110, which is located at an edge of the coverage of the light emitting device layer 1510, may have an area different from other portions or all of the terminals 110; alternatively, at least one of the terminals 110, which is located within the coverage of the light emitting device layer 1510, may have an area different from other portions or all of the terminals 110. Alternatively, at least one terminal 110, which is located at an edge of the coverage of the light emitting device layer 1510, may have an area greater or smaller than other portions or all of the terminals 110; alternatively, at least one of the terminals 110, which is located within the coverage of the light emitting device layer 1510, may have an area greater or smaller than that of other portions or all of the terminals 110. In some embodiments, the area of some or all of the plurality of terminals 110 may be the same.

Referring to fig. 6, in some embodiments, a distance D between at least one terminal 110 located at an edge of a coverage of the light emitting device layer 1510 and an adjacent at least one terminal 110 may be different from an average distance D between the terminals 110. As shown in fig. 6, assuming that a distance between the two lowermost terminals 110 is an average distance D between the terminals 110, the two rightmost terminals 110 are located at edges of a coverage of the light emitting device layer 1510, and the distance D between the two rightmost terminals 110 may be greater than the average distance D between the terminals 110. Alternatively, the pitch D between the rightmost two terminals 110 may be smaller than the average pitch D between the terminals 110. In some embodiments, the spacing D between the leftmost two terminals 110 may be greater than or less than the average spacing D between the terminals 110. Alternatively, the distance d between the terminals 110 at different positions may be flexibly set according to practical situations such as process requirements.
