[0020] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] This application proposes an easily detachable display module, please refer to Figure 1 , including: a cover plate 10, an upper glass substrate 11, a lower glass substrate 12, a liquid crystal layer 13, a backlight assembly 20 and an adhesive 30. The cover plate 10, the upper glass substrate 11, the lower glass substrate 12 and the backlight assembly 20 are stacked in sequence, the adhesive 30 includes an adhesive layer 31 and a filling layer 32, the adhesive layer 31 and the filling layer 32 are connected, both sides of the adhesive layer 31 are adhesive, and the filling layer 32 is not adhesive, the adhesive 30 is arranged between the lower glass substrate 12 and the backlight assembly 20, the lower glass substrate 12 and the backlight assembly 20 are bonded by the adhesive layer 31, and the adhesive 30 is aligned with the lower glass substrate 12 and the backlight assembly 20. When the staff tear and separate the backlight assembly 20 and the lower glass substrate 12 by external force, since the filling layer 32 is not adhesive, the staff can start to separate the backlight assembly 20 and the lower glass substrate 12 from one side of the filling layer, reduce the stress between the two, reduce the difficulty of the staff's work, and ensure the functional integrity of the backlight assembly 20 and the lower glass substrate 12 to a certain extent. Preferably, the cover plate 10 is a TP cover plate. It should be noted that polarizers are disposed on both sides of the liquid crystal layer 13 to selectively filter out light in certain directions.

[0026] Since the function of the adhesive 30 is to connect the lower glass substrate 12 and the backlight assembly 20, it only needs to meet the bonding between the lower glass substrate 12 and the backlight assembly 20, so the thickness of the adhesive 30 is smaller than the thickness of the cover plate 10, the upper glass substrate 11, the lower glass substrate 12 and the backlight assembly 20, so that the structure occupies less space and is more compact as a whole. Preferably, the adhesive 30 is opaque black glue.

[0027] See also Figure 1, the display module of the present application also includes FPC40, the length of the lower glass substrate 12 is consistent with the length of the cover plate 10, and a notch 111 is provided at the edge of the upper glass substrate 11 and the liquid crystal layer 13, and the notch 111 is used to provide a connection position for the connection of the FPC40, and one end of the FPC40 is connected to the notch 111, and the notch 111 is provided directly above the filling layer 32. During the assembly process, since the filling layer 32 is not sticky, the staff does not need to press the filling layer 32 and the notch 111, so as to prevent the edge of the lower glass substrate 12 from being unsupported at the notch 111 and the lower glass substrate 12 from being pressed and broken. In order to ensure that the connection between the backlight assembly 20 and the lower glass substrate 12 is sufficiently firm, the length of the adhesive layer 31 is greater than the length of the filling layer 32, and the width of the adhesive layer 31 is greater than the width of the filling layer 32, and the adhesive layer 31 and the filling layer 32 are connected to form a rectangular parallelepiped structure.

[0028] In one embodiment, the backlight assembly 20 includes a backlight source assembly, a reflective sheet, a light guide plate, a backlight plate, an upper light enhancement plate, a lower light enhancement plate, and a diffusion plate. The backlight source assembly is arranged on the side of the backlight plate, the reflective sheet, the light guide plate, the diffusion plate, the lower light enhancement plate, and the upper light enhancement plate are stacked in sequence and arranged on the backlight plate, the reflective sheet abuts against the backlight plate, the light emitted by the backlight source assembly is reflected to the light guide plate via the reflective sheet, and the light passes through the light guide plate, the diffusion plate, the lower light enhancement plate, and the upper light enhancement plate in sequence. The light guide plate converts the point light source of the backlight source assembly into a surface light source for uniform illumination, the upper light enhancement plate and the lower light enhancement plate gather the scattered light emitted by the backlight source assembly in the front direction to increase the brightness, the diffusion sheet diffuses the light so that the light is more evenly illuminated, and the reflective sheet is used to enhance the brightness of the light. Furthermore, the backlight panel includes a backlight bracket and a plastic layer. The backlight bracket is made of an iron frame, and the plastic layer is made of plastic material. The plastic layer covers the backlight bracket. Since the density of plastic is lower than that of iron, the plastic layer is used to reduce the weight of the overall assembly.

[0029] In addition, the backlight source assembly includes at least one LED lamp. Specifically, the backlight source assembly is provided with 16 LED lamps, and the LED lamps are arranged in four rows and four columns on the backlight panel, so that the light emitted by the LED lamp is more uniform. When assembled on the display module, the brightness in the display area will not be inconsistent, and the viewing experience will be better.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
