Abstract: The present invention provides a positioning device for light guide plate and the backlight module. The positioning device for light guide plate includes a backboard and a spring member which can be deformed when exerted with external force, and resumes to its original position when the external force is relieved. The spring member is arranged adjacent to the incident surface of the light guide plate, and includes a connector attached to the backboard, and a positioning hand having a fixing end and a free end. The fixing end is secured to the connector, and the free end abuts against to the sidewall of the light guide plate so as to hold up the light guide plate. The spring member is set to have a certain elastic modulus. When the light guide plate expands under heat or other reasons, the spring member will provide a buffer zone for the light guide plate and deform in accordance with the light guide plate which is therefore prevented from being warped. Once the light guide plate resumes to its original position, then the spring member resumes also back to its original position. As a result, the light guide plate is constantly kept in position by the positioning device made in accordance with the present invention. Accordingly, the coupling distance between the light guide plate and the light source can be ensured. This will increase the light quality of the backlight module. In addition, the positioning device can ensure reliable and durable positioning to the light guide plate.
Abstract translation: 本发明提供一种导光板和背光模块的定位装置。 用于导光板的定位装置包括背板和弹簧构件，当外力施加时弹簧构件可以变形，并且当外力被释放时恢复到其初始位置。 弹簧部件配置在导光板的入射面附近，并且包括连接到背板的连接器，以及具有固定端和自由端的定位手。 固定端固定在连接器上，自由端抵靠导光板的侧壁，以便保持导光板。 弹簧构件设定为具有一定的弹性模量。 当导热板在加热或其他原因下膨胀时，弹簧构件将为导光板提供缓冲区，并根据导光板变形，从而防止其翘曲。 一旦导光板恢复到其初始位置，则弹簧构件也恢复到其初始位置。 结果，导光板通过根据本发明制造的定位装置恒定地保持就位。 因此，可以确保导光板与光源的耦合距离。 这将增加背光模块的光质。 此外，定位装置可以确保对导光板的可靠和耐用的定位。
