However, in actual situations, the width of the gap 28 above the display substrate 26 is limited. If the above method is adopted, the spacer may be pushed beyond the range of the gap 28 after the glass cover plate 20 is pressed together; There is a polarizer on the top, and it falls from the side edge of the polarizer, which will still cause the optical glue 29 to overflow
Therefore, there is still room for improvement with the above approach

Embodiment Construction
[0021] Figure 2A It is a schematic diagram of an embodiment of the display device 100 of the present invention. As shown in FIG. 2 , the display device 100 has a display module 200 and a backlight module 300 . The display module 200 includes a display panel, an outer cover 202 and a compressible rubber strip 204 . The display panel includes a substrate set 210 with a display surface, an upper polarizer layer 208 a attached to the display surface, and a lower polarizer layer 208 b attached to the back of the substrate set 210 . The substrate set 210 preferably includes an upper substrate 210a and a lower substrate 210b. In this embodiment, the upper substrate 210a is a substrate containing a color filter layer, and the lower substrate 210b is a substrate carrying a thin film transistor layer, but not limited thereto. A liquid crystal layer (not shown) is preferably sealed between the upper substrate 210a and the lower substrate 210b to modulate light to generate images.

A display module is provided. The module comprises a display panel, an outer cover plate and a compressible adhesive tape. The display panel comprises a substrate group with a display surface and a polarized light layer adhered to the display surface. The polarized light layer is provided with a first end edge, and a segment difference is formed on the substrate group. The outer cover plate is arranged outside the substrate group and is used for allowing the display surface to display images outside through the outer cover plate. The compressible adhesive tape is arranged between the substrate group and the outer cover plate and extended along the first end edge. The compressible adhesive tape is covered on the polarized light layer and the substrate group and strides over the segment difference, The part of the compressible adhesive tape covering on the polarized light layer is compressible compared with the part covering on the substrate group. The display module can be used for preventing optical glue from spilling.
Description
technical field [0001] The present invention relates to a display module; in particular, the present invention relates to a display module with compressible adhesive strips. Background technique [0002] In the assembly process of display devices, especially for notebook computers, tablet computers and large-size display devices, in order to improve the assembly yield, the direct bonding method is often used at present, that is, the display panel is first bonded to the glass. The cover plate and the touch module are bonded together, and then the backlight module is assembled. However, with the full lamination method, there will be a problem of glue overflow, as detailed below. [0003] figure 1 It is a schematic diagram of a conventional display device. like figure 1 As shown, in the display device 10 , the display module 20 includes a glass cover 22 , a polarizing layer 24 and a display substrate 26 . Before the full lamination, the optical glue 29 is coated on the pol...
