Problems solved by technology
Although the alignment method of laser marking can basically guarantee the alignment accuracy of FPC, due to the high cost of forming alignment marks by laser, the economic cost of the display module is increased.
At the same time, forming an alignment mark on the backplane by means of a laser will inevitably make the laser mark have a certain depth on the backplane, resulting in lower strength of the backplane
Backplanes with laser markings are easily broken or damaged when subjected to external shocks
Especially for thin and light display modules, too low strength of the backplane will also affect the yield of the entire display device production, increasing the difficulty of the process

Embodiment Construction
[0044] Aiming at the problem of realizing a low-cost, high-yield alignment FPC, the present application provides a display module and a display device. In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described below in conjunction with the accompanying drawings and embodiments.
[0045] It should be noted that specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar promotions without departing from the connotation of the present application. The present application is therefore not limited by the specific embodiments disclosed below.
[0046] On the one hand, if figure 2 As shown, the present application provides a schematic diagram of the back of...

The present application provides a display module and a display device, which are characterized in that they include a display panel, an alignment tape and a flexible circuit board; the alignment tape is arranged on the side of the display panel away from the light-emitting surface, and the flexible The circuit board is disposed on a side of the alignment tape away from the display panel. In this application, the FPC is accurately aligned and fixed on the backplane by arranging an alignment tape on the backplane of the display module. Different from traditional laser alignment marks, the FPC alignment provided by this application saves costs in the production process due to the use of relatively cheap adhesive tape. At the same time, since the cutting accuracy of the tape is easier to control than the laser marking accuracy, and the cutting accuracy of the tape also meets the requirements, the alignment accuracy of the FPC is also guaranteed.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] As a display component, a display device has been widely used 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 usually includes a backlight module, a flexible printed circuit (FPC), a heat dissipation component, and the like. In order to ensure the normal operation of the display panel, the above-mentioned components need to be accurately and stably stored in the display module. For example, after the FPC is pressed and bonded with the display module, it needs to be bent to the backplane of the backlight module. Since the FPC is bent along the backplane, there will be inaccurate alignment, which will easily cause deviations in the position of the FPC aft...
