The present invention provides a display module 100. It is understood that the display module 100 can be applied to a mobile phone, a television, a digital camera, a computer, etc.
Referring to fig. 1 to 5, in an embodiment of the present invention, the display module 100 includes:
the storage space is formed on the inner side of the middle frame 10, an accommodating groove 11 is formed in the surface of the inner side of the middle frame 10, and a notch of the accommodating groove 11 faces the storage space;
the optical assembly 20 is arranged in the accommodating space, and the edge of the optical assembly 20 is inserted into the accommodating groove 11;
the display panel 30 is arranged on the front surface of the optical assembly 20 in a covering manner;
the back plate 40 covers the back surface of the optical assembly 20, and the edge of the back plate 40 is located on the side of the edge of the optical assembly 20 away from the display panel 30.
In the conventional technology, in order to implement a narrow-frame full-screen design, a display module as shown in fig. 1 is usually adopted, a fastening fixing flange 41 is adopted between the middle frame 10 and the back plate 40, since the optical assembly 20 needs a certain thermal expansion space in a direction parallel to the display panel 30, a certain space is generally reserved in the middle frame 10 for the expansion of the optical assembly 20, and the existing back plate 40 is installed at a side of the optical assembly 20, i.e., between the middle frame 10 and the optical assembly 20, so that the middle frame 10 needs to reserve a connection space with the back plate 40, the middle frame 10 cannot be extremely narrow, and meanwhile, the expansion space of the optical assembly 20 may be insufficient to affect the assembly reliability of the middle frame 10. Therefore, in the present invention, the accommodating groove 11 is formed in the middle frame 10, the optical assembly 20 is mounted in the accommodating groove 11, the back plate 40 is disposed outside the accommodating groove 11, i.e., on the back side of the optical assembly 20, and no additional space for mounting the back plate 40 is reserved between the optical assembly 20 and the middle frame 10, so that not only is the space of the middle frame 10 in the horizontal direction (along the length direction of the display panel 30) reduced, but also the optical assembly 20 has sufficient expansion space, and at the same time, the distance from the visible area of the display panel 30 to the outside of the middle frame 10 is reduced. The middle frame 10 and the display panel 30 may be fixed by gluing, and the display panel 30 is covered on the front surface of the optical assembly 20, where the front surface of the optical assembly 20 refers to a display surface of the optical assembly 20, that is, a surface facing a display screen, and the back surface of the optical assembly 20 refers to a backlight surface of the optical assembly 20, that is, a surface facing away from the display screen.

The optical assembly 20 includes an optical film, a light guide plate, and a reflective sheet, which are sequentially stacked. The back plate 40 is made of a strong and rigid material, such as metal or rigid plastic, for providing support and protection in the overall structure. The optical film is used to improve the backlight effect of the display panel 30, and the optical film may be a polarizing film for adjusting the light polarization effect, an antireflection film for increasing the light brightness, a diffusion film for improving the light uniformity, a filter film for filtering out stray color light, and the like. The light guide plate can change the propagation direction of light rays so that the light rays are emitted from the light guide plate toward the optical film as much as possible, providing a backlight for the display panel 30. The reflective sheet may be a thin film or layer made of a high-reflectivity material, and light reaching the reflective sheet is sufficiently reflected back to the display panel 30, which helps to provide a high-efficiency backlight to the display panel 30.
According to the technical scheme of the invention, the combination surface of the back plate 40 and the middle frame 10 is changed from the side edge of the optical assembly 20 to the back surface of the optical assembly 20, namely, a space for installing the back plate 40 does not need to be additionally reserved between the optical assembly 20 and the back plate 40, so that the size from the visible area of the display panel 30 to the outer side of the middle frame 10 is reduced. Specifically, the inner side surface of the middle frame 10 is provided with a containing groove 11 for installing the optical assembly 20, the display panel 30 is covered on the front surface of the optical assembly 20, the back plate 40 is covered on the back surface of the optical assembly 20, and the edge of the back plate 40 is located on the side of the edge of the optical assembly 20, which is away from the display panel 30, as can be understood, the combination of the back plate 40 and the middle frame 10 is arranged outside the containing groove 11, so that a space for installing the back plate 40 is not required between the side edge of the optical assembly 20 and the inner surface of the middle frame 10, and the space arrangement of the middle frame 10 in the direction parallel to the length direction of the display panel 30 is saved. Therefore, according to the invention, the size from the visible area of the display panel 30 to the outer side of the middle frame 10 is reduced by changing the mounting positions of the back plate 40 and the middle frame 10, so that the middle frame 10 can achieve an extremely narrow effect as much as possible, a comprehensive screen design with ultra-narrow frames or even no frames is realized, meanwhile, the arrangement of buckles is saved, and the production efficiency of the display module is improved.
