Embodiment Construction

[0046] image 3 is a partial schematic diagram of a backlight module according to an embodiment of the present invention, and Figure 4 for image 3 The cross-sectional view of the backlight module. Please refer to image 3 and Figure 4 , the backlight module 300 is mainly composed of a light reflector 310 , a light guide plate 320 and a linear light source 340 . The light guide plate 320 has an incident side 322 , a back surface 324 and a light emitting surface 326 . The incident side 322 of the light guide plate 320 is embedded in the light reflection cover 310 . The linear light source 340 is disposed between the light reflection cover 310 and the incident side 322 of the light guide plate 320 . The light emitted by the linear light source 340 is reflected and concentrated by the light reflector 310, enters the light guide plate 320 from the incident side 322 of the light guide plate 320, and is converted into a surface light source by the function of the light guide...

Abstract

The invention relates to a laptop computer, a negative phototropic module and a light guiding pate. The laptop computer is formed by a host machine and a liquid crystal display apparatus. The liquid crystal display apparatus is connected with the host machine and is formed by a liquid crystal display plate and a negative phototropic module. The negative phototropic module is positioned under the liquid crystal display plate. The negative phototropic module is formed by a light reflecting cover, a light guiding plate and a linear light source. The light guiding plate possesses an association side. The association side is embedded in the light reflecting cover. The linear light source is positioned between the light reflecting cover and the light guiding plate. The light reflecting cover is touched on the surface of the light guiding plate.

Description

technical field [0001] The present invention relates to a computer, a light source module and its light guide plate, and in particular to a notebook computer, a back light module and its light guide plate. Background technique [0002] With the rapid development of science and technology, powerful and portable notebook computers have played an extremely important role in people's lives. The display screen of notebook computer is mainly based on liquid crystal display. However, since the liquid crystal display itself does not have the function of emitting light, a backlight module must be provided under the liquid crystal display to provide a light source to achieve the display function. [0003] figure 1 is a schematic diagram of a known notebook computer, and figure 2 It is a schematic cross-sectional view of a known backlight module in a notebook computer. Please refer to figure 1 , the notebook computer 20 is composed of a host computer 30 and a liquid crystal displ...
