Embodiment Construction

[0025] In order to have a further understanding of the purpose, structure, features and functions of the present invention, the detailed description is as follows in conjunction with the embodiments.

[0026] see Figure 1 to Figure 3 . The display device 1 according to an embodiment includes a front frame 12 , a back cover 14 , a liquid crystal panel 16 , a backlight module 18 and a control module 20 . The front frame 12 is engaged with the back cover 14 to form an accommodating space for accommodating other components. The front frame 12 has a window 122 through which the liquid crystal panel 16 is exposed. The practical application of the liquid crystal panel 16 can be the liquid crystal panel of a general liquid crystal display as an example, and will not be repeated here. The backlight module 18 is disposed under the liquid crystal panel 16 to provide backlight for displaying images on the liquid crystal panel 16 . The control module 20 is electrically connected with ...

Abstract

The invention discloses a backlight module which comprises a light guide plate, a wavelength conversion layer and an opaque layer. The light guide plate has a light emitting surface and a side surface. The light emitting surface has a side, and the side surface is adjacent to the side. The light emitting surface includes an intermediate portion and an edge portion, and the edge portion extends along the side. The wavelength conversion layer covers the intermediate portion. The opaque layer covers the edge portion such that light in the light guide plate is not emitted from the edge portion tobecome backlight.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module using a light guide plate. Background technique [0002] Many backlight modules use a light guide plate to guide light to provide, for example but not limited to, a flat backlight for a liquid crystal display panel. However, the side surface of the light guide plate also reflects light, so that the brightness of the surrounding parts of the light-emitting surface is improved. In this case, in the backlight module using the quantum dot film, the surrounding part of the backlight module will also have a bluish phenomenon, which will affect the image display. When the display adopts a narrow frame design, the above-mentioned bright and bluish phenomenon is difficult to be covered by the frame of the display in principle. Contents of the invention [0003] In view of the problems in the prior art, the purpose of the present invention is to provide a backlight module, which...
