Embodiment Construction
[0028] 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.
[0029] The invention provides a luminous keyboard, in particular, a luminous keyboard using light emitted from the edge of a light guide sheet. Specifically, the light-emitting keyboard of the present invention can be any independent keyboard device with light-emitting keys or a light-emitting keyboard integrated in electronic products (such as keys or keyboards equipped with mobile devices, tablet computers, etc.), but is not limited thereto. Taking a computer keyboard as an example, the details of the luminous keyboard according to the embodiment of the present invention will be described in detail with reference to the drawings.
[0030] Such as figure 1 As shown, in one embodiment, the luminous keyboard 1 of the present invention includes a key module 10 and a backlight mod...

The invention provides a luminescent keyboard, which comprises a key module with a plurality of key units and a backlight module arranged below the key module, wherein the backlight module comprises alight guide plate, a shading sheet and a light source unit; the light guide plate comprises a plurality of light guide sheets which are arranged at intervals corresponding to the plurality of key units and are mutually locally connected with the help of connection parts, and a light guide sheet gap exists between light outgoing side surfaces of adjacent light guide sheets; the shading sheet comprises a plurality of light transmission parts with light transmission part edges, and vertical projection of the light outgoing side surface of each light guide sheet on the corresponding light transmission part is located in the light transmission part, and a light outgoing gap exists with the edge of the light transmission part; and the light source unit comprises a light source circuit layer anda plurality of luminescent elements, each luminescent element provides light towards a corresponding light incoming side surface, and each light guide sheet guides at least part of the light to be ejected to the corresponding key unit from the light outgoing side surface via the light outgoing gap.
Description
technical field [0001] The present invention relates to a luminous keyboard, in particular, the present invention relates to a luminous keyboard emitting light from the edge of a light guide sheet. Background technique [0002] In order to operate the keyboard smoothly in a dim environment, light-emitting keyboards have gradually become the first choice of consumers. Conventional light-emitting keyboards usually use several light-emitting diodes as light sources, and use a light guide plate corresponding to the size of the keyboard to achieve the lighting effect of the entire keyboard. However, as the distance between the key and the light source is different, the luminance of the key is also different, resulting in poor uniformity of the overall light emission of the keyboard and affecting the visual effect. [0003] Therefore, how to improve the luminous uniformity of the luminous keys is one of the key points in the design of the luminous keyboard. Contents of the inve...
