Abstract

A display device which can be put together without hooks or fasteners includes an outer frame and a backplane. The outer frame includes a side frame and a T-shaped fixture block protruding from the side frame. The backplane includes a side board. A T-shaped groove is formed on the side board. The T-shaped groove extends through the side board. The T-shaped groove includes a first groove and an inwardly extending groove communicating with the first groove. The fixture block can be inserted into or removed from the first groove. The fixture block can be moved along the inwardly extending groove to engage with the two sides of the inwardly extending groove.

Description

    FIELD
  • The subject matter generally relates to structure of a display device.
    • BACKGROUND
  • A television includes a display screen and a back plate. The display screen and the back plate may be connected by deformable hooks or screw locks. However, such hooks on the outer frame may easily break during assembly and disassembly, and the hooks on the outer frame need to be replaced when they are broken. Moreover, broken screw locks may fall inside the interior of the television, where they can cause damage to the television.
  • Thus, there is room for improvement in the art.
