Description
Technical Field

Background
Display devices have been widely used as display components in various electronic products, such as mobile phones, tablet computers, and the like. At present, a display device is composed of a display module and a display module, wherein the display module generally includes a backlight module, a Flexible Printed Circuit (FPC), a heat dissipation member, and the like. In order to ensure the normal operation of the display panel, the above components need to be accurately and stably accommodated in the display module. For example, after the FPC is press-fitted to the display module, the FPC needs to be bent onto a back plate of the backlight module. Because FPC can have the inaccurate condition of counterpointing when buckling along the backplate, causes the FPC to buckle the position after the deviation easily.
In the prior art, as shown in fig. 1, in a display module 10, a mark 13 (shown by a bold line segment in the figure) is generally formed on a back plate of a display panel 11 by laser, an FPC12 is aligned with the mark 13, and the FPC is fixed by an adhesive tape 14, thereby completing accurate storage of the FPC. Although the alignment mode of the laser mark can basically ensure the alignment precision of the FPC, the alignment mark formed by the laser mode has higher cost, so that the economic cost of the display module is increased. Meanwhile, forming the alignment mark on the back plate by using a laser method inevitably makes the laser mark have a certain depth on the back plate, resulting in low strength of the back plate. The back plate having the laser mark is easily broken or damaged when being impacted from the outside. Especially for the light and thin display module, too low strength of the back plate can also influence the yield of the whole display device, and the process difficulty is increased.
Therefore, how to accurately align the FPC with low cost and high yield is an urgent problem to be solved in the field.

Detailed Description
To the problem of realizing low-cost, high yield counterpoint FPC, this application provides a display module assembly and display device. In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is further described with reference to the accompanying drawings and examples.
It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import to those skilled in the art without departing from the spirit and scope of this application. The present application is therefore not limited to the specific embodiments disclosed below.
In one aspect, as shown in fig. 2, the present application provides a schematic back view of a display module 100, which includes a display panel 101, a flexible circuit board (FPC)102, and an alignment tape 103; the alignment tape 103 is disposed on a side of the display panel 101 away from a light emitting surface (shown by an arrow direction in the figure), and the flexible circuit board 102 is disposed on a side of the alignment tape 103 away from the display panel 101. Those skilled in the art will appreciate that the display module 100 may further include an electronic component 104 disposed on the FPC, and the electronic component 104 may include an IC chip, a processor, and the like, which is not limited herein. Because the alignment adhesive tape is arranged between the display panel and the FPC, the alignment of the FPC and the display panel can be realized by utilizing the geometric characteristics of the alignment adhesive tape, such as edge lines, holes and the like.
In some alternative embodiments, as shown in fig. 3 and 4, the alignment tape 103 includes a first alignment mark 1031, the FPC102 includes a second alignment mark 1021, the first alignment mark 1031 matches with the second alignment mark 1021, and both the first alignment mark 1031 and the second alignment mark 1021 are alignment lines. Specifically, when the FPC102 is aligned with the display panel 101, the contour 1021 of the FPC and the contour 1031 of the alignment tape are aligned in the direction perpendicular to the display panel by observation with human eyes, and then the accurate position of the FPC is determined. Because the FPC is a complete component, one end of the FPC is connected to the display panel, and the other end of the FPC is connected to the main board after being fixed, the FPC can be fixed at any position of the FPC, and the whole FPC can be fixed. Referring to fig. 3, the first alignment mark 1031 is disposed only on a portion of the edge profile of the alignment tape, for example, the first alignment mark may be disposed on the edge of the end portion near the upper portion of the display panel. Similarly, the second alignment mark 1021 is only arranged on a part of the edge profile of the FPC, and matches with the first alignment mark 1031.
Further, the contour of at least part of the alignment adhesive tape is the same as that of the flexible circuit board. That is, the first alignment mark 1031 and the second alignment mark 1021 may be set to completely coincide. Of course, the first alignment mark and the second alignment mark may be arranged in other matching relationships, for example, may be arranged in a pattern having a complementary relationship such as a latch.
Further, in the direction perpendicular to the display panel, the projection of the alignment tape is located within the projection of the flexible circuit board, that is, the alignment tape is located within the area of the FPC. As shown in fig. 5, the outline of the alignment tape is identical to the outline of the FPC, i.e. the projection of the alignment tape is located within the projection of the FPC in the direction perpendicular to the display panel. Of course, the area of the alignment tape may be set to be not larger than the area of the FPC, for example, may be set to extend only along the edge of the lower portion of the display panel, as shown in fig. 6.
Further, as shown in fig. 7 and 8, the first alignment mark 1031 and the second alignment mark 1021 may be circular holes. Specifically, when the FPC102 is aligned with the display panel 101, the alignment hole 1021 of the FPC and the alignment hole 1031 of the alignment tape are aligned in a direction perpendicular to the display panel by observation of human eyes, and then the accurate position of the FPC is determined. Those skilled in the art will understand that the alignment mark can be disposed in various forms of a point, a line, a protrusion, and a recess, and the alignment mark is not limited herein as long as the alignment can be achieved.
The inventors confirmed that the precision of cutting and attaching the adhesive tape can meet the production requirements through actual measurement. Generally, the position and accuracy of the FPC is defined by the distance from the FPC to a side edge of a cover plate of the display panel. The calculation of the precise positioning of the tape cutter can be estimated as follows: the adhesive tape attaching precision is +/-0.2 mm, the alignment precision of the adhesive tape protective film cutter is +/-0.01 mm, the size precision of the display panel is +/-0.1 mm, the attaching precision of the cover plate is +/-0.15 mm, the precision of the FPC attached to the display panel is +/-0.01 mm, and the precision of the FPC manufacturing appearance is +/-0.1 mm. Therefore, the tolerance of FPC position resulting from the whole production process is: sqr (0.22+0.012+0.12+0.152+0.012+0.12) < + -0.3mm in 0.2876mm, which can meet the current production requirement. Table 1 shows the error values of the alignment tape process measured by the experiment. The final specification value of 19.54+0.5/-0.3mm is obtained by measuring the position values of the tape release film in alignment of the alignment tape 1 and the alignment tape 2 designed according to the method of the embodiment for multiple times, and the value meets the production requirement. Meanwhile, the adhesive tape design method has a smaller and more stable process capability index CPK, so that the alignment method can achieve higher alignment precision.
