Description

Display module Technical Field The disclosure belongs to the technical field of display, and particularly relates to a display module. Background With rapid development of display technologies, organic Light-Emitting Diode (OLED) display technologies are gradually advancing to medium and large-sized products, and products such as Television (TV)/touch panel display (TPC)/notebook computer (NB) gradually adopt OLED display panels to replace traditional Liquid crystal (Liquid CRYSTAL DISPLAY, LCD) display panels. The frame of the display panel needs to be reduced as much as possible to be compatible with different types of products. However, due to the problem of excessive edges of the touch substrate, the touch is very easy to generate to cause cracking of the crack during the display module process and the whole machine assembly process, thereby causing the problems of touch failure and the like. Disclosure of Invention The invention aims to at least solve one of the technical problems in the prior art and provides a display module. The technical scheme includes that the display module comprises a display panel, a touch substrate and a composite film layer, wherein the touch substrate is located on the light-emitting surface side of the display panel, the composite film layer is located on the side, away from the light-emitting surface side, of the display panel, a supporting component is arranged in the edge area of the touch substrate and is located at least on two opposite sides of the touch area of the touch substrate, the supporting component is used for connecting the touch substrate with the composite film layer and limiting a containing space, and the display panel is located in the containing space. In some embodiments, the support assembly is an integrally formed structure with the composite membrane layer. In some embodiments, the support assembly and the composite membrane layer are integrally formed and form a U-shaped member. In some embodiments, the touch substrate includes a substrate layer and a touch assembly disposed on a side of the substrate layer away from the display panel, where the support assembly and the substrate layer are integrally formed. In some embodiments, the support assembly and the substrate layer are integrally formed and form a U-shaped member. In some embodiments, the side surface of the support component away from the accommodating space is projected forward on the plane where the display panel is located, and falls on the outline of the projected forward of the touch substrate on the plane where the display panel is located. In some embodiments, the display module further includes a polarizer located at a side of the touch substrate facing away from the display panel, a cover plate located at a side of the polarizer facing away from the touch substrate, and a first adhesive layer for adhering the cover plate and the polarizer. In some embodiments, the first adhesive layer covers the touch substrate. In some embodiments, the display module further includes a second adhesive layer between the display panel and the touch substrate, the second adhesive layer filling a gap between the display panel and the touch substrate in the accommodating space. In some embodiments, the composite film layer includes a conductive heat dissipation layer, a buffer layer, and a third adhesive layer sequentially disposed in a direction adjacent to the display panel.
