BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a liquid crystal display (LCD) assembly. 
     2. Description of Related Art 
     LCD devices are widely applied in electronic products such as television (TV) sets and computers. Usually, the LCD devices are mounted in a metallic inner frame and the inner frame is received in a plastic outer frame. The outer frame includes extending hooks for clamping the inner frame. When disassembling the LCD device, the hooks are pressed to disengage the inner frame, and the inner frame is pried out of the outer frame by tools such as a screwdriver. It is inconvenient to disassemble the LCD devices. 
     Therefore, it is desirable to provide a disclosure, which can overcome the limitations described.

The toothed bar  424  spatially corresponds to a receiving groove  2054  and includes a plurality of teeth for meshing with the gear  421 . 
     The LCD device  50  is received in the receiving space  103  for displaying images. 
     Referring to  FIGS. 2 to 5 , when assembling, the two screw holes  323  of each connection element  32  are aligned to the two mounting holes  1023  of a fourth surface  1022 , each connection element  32  is mounted to a fourth surface  1022  by two screws  43 . The two springs  33  of each clamping component  30  are respectively sleeved the outside of the shaft portions  313  of a hook  31 . The two shaft portions  313  are received in the two pivoting holes  2025  of an opening  2023 . Each spring  33  presses on an inner surface  2024 . Each toothed bar  424  is received and is adhered in a receiving groove  2054 . Each reposition spring  423  is sleeved around the outside of the rotation shaft  422 . The rotation shaft  422  is fitted into the central hole  4211  of the gear  421 . One end of the reposition spring  423  is fixed between the pair of protrusions  416  of one of the mounting surfaces  415 . The other end of the reposition spring  423  is fixed in the mounting groove  4212  of the gear  421 . Each gear  421  is received in the receiving gap  414  with the rotation shaft  422  mounted into the blind holes  417 , such that the gear  421  can be rotated about the rotation shaft  422 . The reposition spring  423  is in an initial position having no deformation. The two through holes  413  of each holding member  41  are aligned to the first aligning hole  1013  and the second aligning hole  1021  and each holding member  41  is fixed to the first frame  10  by two screws. Each base portion  411  holds the first frame  10 . Each hold member  41  is received in a leading groove  205 . 
     The four ejecting components  40  are mounted at four corners of the first frame  10 . Each hook  31  is pressed to rotate to a corresponding eighth surface  2022 , such that the first frame  10  can be pressed into the second frame  20  with each gear  421  meshing with a corresponding toothed bar  424 . Each gear  421  is rotated about the shaft portion  422  and the reposition spring  423  of each ejecting component  40  generates deformation, the two stoppers  4113  of each holding member  41  are received in two engaging grooves  2053  of a corresponding leading groove  205 . Then, each hook  31  is released and the hook portion  312  presses on the contact portion  322  of a connection element  32 . The first frame  10  is clamped in the second frame  20  by the two clamping components  30  mounted between the first frame  10  and the second frame  20 . The reposition spring  423  of each ejecting component  40  provides a driving force to the gear  421  to rotate back to the initial position. 
     Referring to  FIGS. 3 ,  6  and  7 , when disassembling the first frame  10  from the second frame  20 , each hook  31  is pressed to move away from a corresponding contact portion  322 . The reposition spring  423  drives the gear  421  of each ejecting component  40  to rotate back to the initial position with the diving force, the gear  421  moves relative to the toothed bar  424 , such that the first frame  10  is ejected out of the second frame  20  by the ejecting components  40 . Therefore, it is convenient to disassemble the first frame  10 . 
     The clamping components  30  clamp the first frame  10  in the second frame  20 . The ejecting components  40  provide a driving force for ejecting the first frame  10  out of the second frame  20 . In alterative embodiments, the number of the clamping components  30  and ejecting components  40  is not limited.
