Embodiment Construction
[0055] Figure 2A It is a partial cross-sectional view of a backlight module according to an embodiment of the present invention, and image 3 for Figure 2A A three-dimensional schematic diagram of the backlight module. Please refer to Figure 2A , the backlight module 200 of this embodiment includes a frame 210 , a light guide plate 220 , a light source carrier 230 and at least one light source element 240 . The frame 210 has at least one first positioning structure 212 . The first positioning structure 212 in this embodiment is an insertion hole, but the first positioning structure 212 may also be any other suitable positioning structure. The light guide plate 220 is disposed in the frame 210 and surrounded by the frame 210 , and has a light-emitting surface 222 and a light-incident surface 224 adjacent to the light-emitting surface 222 . Wherein, there may be direct contact or other components between the light guide plate 220 and the frame 210 . For example, the frame...

The invention discloses a backlight module and a liquid crystal display applying same. The liquid crystal display comprises the backlight module and a liquid crystal display panel; the backlight module comprises a framework, a light guiding plate, a light source carrier and at least one light source element; the framework is provided with a first positioning structure; the light guiding plate is arranged in the framework and surrounded by the same and is provided with a light emitting surface and a light incident surface abutted on the light emitting surface; the light emitting surface and the light injecting surface are exposed by the framework; the light source carrier is provided with at least one second positioning structure which can be combined with the first positioning structure to enable the light source carrier to cover the light incident surface; the light source element is fixed on the light source carrier and positioned besides the light injecting surface; and the liquid crystal display panel is arranged on the light emitting surface of the backlight module.
Description
technical field [0001] The present invention relates to a light source module and a display device using the light source module, and in particular to a backlight module and a liquid crystal display (LCD) using the backlight module. Background technique [0002] With the advancement of modern video technology, liquid crystal display devices have been widely used in mobile phones (mobilephone), notebook computers (notebook personal computer), personal computers (personal computer, PC) and personal digital assistants (personal digital assistant, PDA) Display screens of consumer electronics products. However, since the liquid crystal display panel (LCD panel) of the liquid crystal display device itself does not have the function of emitting light, it is necessary to configure a backlight module under the liquid crystal display panel to provide the light source required by the liquid crystal display panel, so that the liquid crystal display panel can achieve the desired effect o...
