Thedisplay panel 201 is disposed on thelight guide frame 103 of thebacklight module 100 , and thelight guide frame 103 includes afirst part 1031 and asecond part 1032 , thefirst part 1031 is disposed on thehousing 101 , and thefirst part 1031 is disposed around the mainlight source 102 ; Thesecond portion 1032 is disposed on thefirst portion 1031 , and thesecond portion 1032 surrounds thedisplay panel 201 . In thedisplay device 200 of the present embodiment, thelight guide frame 103 is used to carry thedisplay panel 201 , and other components for carrying thedisplay panel 201 are not additionally provided.

当然，显示面板、背光模组的具体结构以及其之间的其他膜层结构，在此不再详述。Of course, the specific structures of the display panel, the backlight module, and other film layer structures therebetween will not be described in detail here.

本发明的显示装置200，其背光模组100设置有导光框架103和辅助光源105，导光框架103除用于承载显示面板201之外，辅助光源105所发出的光线经由导光框架103的传导后自导光框架103传导至背光模组100内部，并与主光源102射至边缘处的光线进行弱化/混和/中和，从而背光模组100所提供的背光源可避免边缘处泛蓝的问题，保证了显示装置200的显示效果。In thedisplay device 200 of the present invention, thebacklight module 100 of thebacklight module 100 is provided with alight guide frame 103 and an auxiliarylight source 105 . Thelight guide frame 103 is used to carry thedisplay panel 201 , and the light emitted by the auxiliarylight source 105 passes through thelight guide frame 103 . After the transmission, the light is transmitted from thelight guide frame 103 to the interior of thebacklight module 100, and is weakened/mixed/neutralized with the light emitted from the mainlight source 102 at the edge, so that the backlight provided by thebacklight module 100 can avoid bluishness at the edge. problem, the display effect of thedisplay device 200 is guaranteed.

依照本发明的实施例，辅助光源所发出的光线与主光源所发出的光线在背光组件的端部进行混合，由此，辅助光源所发出的光线能够弱化/中和主光源所发出的光线，从而能够有效覆盖或转化蓝色光，提高防蓝光效果，进而提升显示装置的显示效果。According to the embodiment of the present invention, the light emitted by the auxiliary light source and the light emitted by the main light source are mixed at the end of the backlight assembly, so that the light emitted by the auxiliary light source can weaken/neutralize the light emitted by the main light source, Therefore, the blue light can be effectively covered or converted, the anti-blue light effect can be improved, and the display effect of the display device can be improved.

当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。Of course, the present invention can also have other various embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding Changes and deformations should belong to the protection scope of the appended claims of the present invention.
