Embodiment Construction

[0021] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0022] Please refer to figure 2 , is a schematic diagram of a light guide plate according to an embodiment of the present invention. The light guide plate 100 includes a light incident portion 110 , a light exit surface 120 , a bottom surface 130 and a side surface 140 . The light emitting surface 120 is opposite to the bottom surface 130 . The light incident portion 110 and the side surface 140 are located between the light exit surface 120 and the bottom surface 130 , and are connected to the light exit surface 120 and the bottom surface 130 . The damage structure 150 is formed on the edge of the light guide plate 100 adjacent to the side surface 140 . In this example, the light guide plate 100 is a rectangular flat plate, and the damage structure 150 is formed ...

Abstract

The invention provides a light guide plate used for a light-emitting keyboard and the light-emitting keyboard. The light guide plate is provided with a light inlet part, a light outlet surface, a bottom surface and a lateral side, wherein the light outlet surface and the bottom surface are oppositely arranged, the light inlet part and the lateral side are located between the light outlet surface and the bottom surface, the bottom surface comprises a plurality of reflection points, light entering the light inlet part is guided outwards through positions, corresponding to the reflection points, of the light outlet surface after being reflected through the reflection points, and one edge, close to the lateral side, of the light guide plate is provided with a damaging structure for preventing the light from overflowing from the lateral side. Because the damaging structure is formed on the light guide plate to prevent light leakage, and the light can be guided outwards through the positions, corresponding to the reflection points, of the light outlet surface after being shot into the reflection points, light-emitting positions can be controlled, for example, a user can just let the center of a key emits light.

Description

technical field [0001] The invention relates to a light guide plate used for a luminous keyboard and a luminous keyboard, in particular to a light guide plate with a destructive structure. Background technique [0002] figure 1 It is a known light-emitting keyboard, including a keyboard part 01 and a light-emitting part 02. The light guide plate 021 is mostly used in the light emitting part 02 together with the side-facing backlight module 022, which can convert the point light source from the side into a surface light source with a front viewing angle, and use the reflection point 021a to guide the light to the keycap 011. However, the angle of light entering from the side cannot be completely converted, and some light sources will overflow from other sides, resulting in light leakage and affecting the aesthetics of the product. Contents of the invention [0003] The invention relates to a light guide plate used for a luminous keyboard, which prevents light leakage by f...
