SPLICING BACKPLANE FOR BACKLIGHT MODULE AND BACKLIGHT MODULE EMPLOYING SAME

摘要

The invention provides a splicing backplane for a backlight module, which is arranged on the backside of the backlight module. The splicing backplane comprises a mounting portion and a supporting portion, wherein the horizontal height of the mounting portion is level with or lower than that of the supporting portion; and a plurality of the splicing backplanes are assembled together by the mutual superposition of various mounting portions. A plurality of the splicing backplanes are superposed with each other and combined into one, and the height differences between the mounting portions and the supporting portions of two adjacent backplanes are unequal, so that one backplane can be accommodated into the other backplane. In addition, after the superposition, the overall thickness of the backplanes is invariable.

1. A splicing backplane for a backlight module, arranged on the backside of the backlight module, wherein the splicing backplane comprises a mounting portion and a supporting portion;
the horizontal height of the mounting portion is level with or lower than that of the supporting portion; a plurality of the splicing backplanes are assembled together by the mutual superposition of various mounting portions; a stepped surface is formed between the mounting portion and the supporting portion of the backplane; the height difference of the stepped surface of one backplane between adjacent backplanes is more than that of the stepped surface of the other backplane; the mounting portions are combined into one through a fastener; in the case of the fastener arranged on side faces of the mounting portions, end portions of the fastener are fastened onto surfaces of the mounting portions to assemble both the mounting portions together; the horizontal height of an inner end portion of the fastener is lower than or level with that of the supporting portion; one splicing backplane is superposed with the other splicing backplane; and the mutually superposed mounting portions of the two backplanes are staggered in such a way that upper portions and lower portions of the splicing backplanes are balanced.
