Embodiment Construction

[0039] see Figure 1 to Figure 6 . figure 1 The light guide plate 1 of the first preferred embodiment of the present invention is schematically shown in top view. figure 2 for figure 1 A partial cross-sectional view of the middle light guide plate 1 along line A-A. image 3 for figure 1 A partial cross-sectional view of the middle light guide plate 1 along line B-B. Figure 4 , Figure 5 and Figure 6 They are partial top views of the light guide plate 1 adjacent to the non-light-incident / non-light-out side 102 of the present invention, respectively. The light guide plate 1 of the present invention can be applied in backlight modules of electronic products such as liquid crystal displays and light-emitting keyboards.

[0040] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the light guide plate 1 of the first preferred embodiment of the present invention includes a substrate 10 , a plurality of microstructures 12 and a plurality of first anti-leakag...

Abstract

The invention provides a light guide plate which comprises a substrate and a plurality of light leakage preventive layers. The substrate is provided with non-incidence / non-emergence side edges, a back surface, a front surface and a plurality of first grooves, each first groove penetrates from the front surface to the back surface, the first grooves are arrayed along the non-incidence / non-emergency side edges, and first preset distances are kept among the various first grooves, so that the non-incidence / non-emergence side edges keep structurally connected with the substrate; each first light leakage preventive layer covers the inner wall of the corresponding first groove and comprises a first shading layer or a first reflecting layer or a combination of the first shading layer and the first reflecting layer, and the first light leakage preventive layers are used for preventing light conducted in the substrate from being transmitted out via the non-incidence / non-emergence side edges when the light is transmitted into the substrate and is conducted in the substrate.

Description

technical field [0001] The present invention relates to a light guide plate, and in particular to a light guide plate capable of blocking light from exiting from a non-light-incoming / non-light-emitting side. Background technique [0002] The light guide plate is a necessary component in the backlight module of electronic products such as liquid crystal displays and luminous keyboards. As this type of electronic product requires a thin and light design, the light sources in the backlight module are all placed on the side of the light guide plate, so that the light enters the light guide plate from the side of the light guide plate, passes through transmission, reflection, and finally emits from the front. These backlight modules do not want light to be emitted from the non-light incident side. [0003] However, there is no light guide plate whose structure can effectively block the light from the non-light-incident side, and these light-blocking structures can be easily manu...
