  • Patent number: 9057902
    Abstract: A fixing device for connecting an optical film with a back plate is disclosed. The fixing device includes a supporting portion, and a protrusive portion. The supporting portion is for connecting to a sidewall of the back plate. The protrusive portion is for passing through a through hole on an extended portion of the optical film such that the optical film is fixed on the back plate. The extended portion extrudes from a main body of the optical film. The fixing devices relate to a pure mechanical or semi-mechanical connection. Such connection structure may prevent the optical film from falling off due to environment changes. In addition, the fixing devices may be used over and over. Furthermore, the connection structure is more compact than the typical ones. The fixing devices not only satisfy the trend toward narrower sidewall of liquid crystal modules, but also prevent the optical film from being bent due to thermal expansion and contraction.
