The second engaging portion  118  engages with the second engaging recess  155 , so as to improve stability of the assembly of the second frame  15  and the back frame  11 . 
     Optionally, the second engaging portions  118  are arranged at intervals in a direction along the peripheral side of the second side wall  113 . Number of each of the second engaging portion  118  and the second engaging recess  155  is plural, and the they are disposed in a one-to-one arrangement to improve the stability of the assembly. 
     A second insertion portion  119  is disposed on a side of the second side wall  113  facing the second support portion  152 . A second insertion slot  156  is defined on the second support portion  152 , and the second insertion portion  119  is inserted in the second insertion slot  156 . 
     When the second frame  15  and the back frame  11  are assembled, the second side wall  113  is prone to deformation due to a thin thickness of the second side wall  113 . As a result, in this embodiment, the second insertion portion  119  and the second insertion slot  156  are configured to be adapted to each other, so as to reduce the risk of deformation of the second side wall  113 . 
     Optionally, number of each of the second insertion portion  119  and the second insertion slot  156  is plural, and they are disposed in a one-to-one arrangement. 
     Optionally, the first engaging portion  116 , the first insertion portion  117 , the second engaging portion  118 , and the second insertion portion  119  are disposed in parallel arrangement in a direction of the thickness of the display module  100 . 
     Please refer to  FIG.  10   . Alternatively, on the basis of the foregoing embodiment, this embodiment replaces the edge-lit first backlight module  12  in the foregoing embodiment with a direct-type first backlight module BU1. 
     Specifically, the first backlight module BU1 includes an LED light board  231 , a holding member  232 , a diffuser plate  233 , and a first optical film  234 . 
     The LED light board  231  is disposed on the first surface  1   a . The holding member  232  is disposed on a peripheral side of the LED light board  231 . An accommodation groove  235  is defined on a side of the holding member  232  away from the first surface  1   a . The diffuser plate  233  is disposed on a light output side of the LED light board  231 , wherein part of the diffuser plate  233  is located in the accommodation groove  235 . The first optical film  234  is disposed on a side of the diffuser plate  233  away from the backplane  111 . 
     Correspondingly, an embodiment of the present application further provides a display module, and the display module is the display module  100  of the display system  1000  of the above-mentioned embodiment as shown in  FIG.  2    to  FIG.  10   . 
     Since the structure of the display module of this embodiment is the same as the structure of the display module  100  of the display system  1000  of the above embodiment, it will not be repeated in this embodiment. For details, please refer to the display module  100  of the display system  1000  in the above-mentioned embodiment. 
     The display module and the display system provided by the embodiments of the present application are described in detail above. Specific examples are used in this article to explain the principles and implementation of this application. The descriptions of the above embodiments are only used to help understand the technical solutions and core ideas of this application. Also, for those skilled in the art, according to the idea of this application, there will be changes in the specific implementation and application scope. In summary, the content of this application should not be construed as a limitation on this application.
