Thus, when an external light is emitted from a light source beneath the keycap, the external light will only pass through one light-transmissible color layer covering that light-transmissible symbol area, and not pass through the light-transmissible color layer covering the other light-transmissible symbol area. Therefore, a bleeding problem due to multiple light-transmissible color layers overlapped and covering the same light-transmissible symbol area is avoided. | 03-24-2016 |
| 20160097896 | LIGHT EMITTING STRUCTURE AROUND A KEYBOARD BACKLIGHT MODULE - A light emitting structure around a keyboard backlight module is disclosed to include a light guiding plate comprising a light source, a flat-shape reflecting layer disposed on one side of the light guiding plate, and a transparent film of a light blocking layer disposed on other side of the light guiding plate and comprising a light absorbing layer. A deflection portion is bending inwardly toward the reflecting layer and then extending outwardly to form a flat-shape positioning portion adhered to the reflection layer by an adhesive layer. The light source can project light toward the light guiding plate and pass part of the light from the light guiding plate to the deflection portion due to diaphaneity of the material of the transparent film. A light emitting area can be formed around the backlight module, lightening the connection port of the electronic device or other area needed to be lightened. | 04-07-2016 |
| 20160109636 | BACKLIGHT MODULE CAPABLE OF AVOIDING LIGHT LEAKAGE - In a backlight module, a shading film connected to the substrate has a first surface, a second surface and a first hole disposed thereon. The light guide plate is connected to the shading film while a second hole with a greater aperture than that of the first hole is disposed thereon. The shading film has an extra extending section compared to the light guide plate and a shading portion is disposed thereon. A third hole with a greater aperture than that of the second hole is disposed on the reflective sheet. A side of the reflective sheet near the third hole has an extra adhesive section while a side of the light guide plate near the second hole does not. The adhesive section connected to the extending section covers a side of the light guide plate near the second hole for preventing light from exiting through the second hole. | 04-21-2016 |
| 20160147004 | BACKLIGHT MODULE HAVING A PRISM STRUCTURE - A backlight module for illuminating a display or keypad is described. The backlight module may be provided in an electronic device along with a light source. In one embodiment, the backlight module comprises: a light diffuser; a light guide located directly below the light diffuser; a prism structure located directly below the light guide, the prism structure having a plurality of prisms extending towards the light guide, wherein an air gap is defined between the prism structure and the light guide; and a reflector located directly below the prism structure. | 05-26-2016 |

| 20160189892 | ILLUMINANT KEYBOARD AND MANUFACTURING METHOD THEREOF - An illuminant keyboard and a method thereof are provided. A plurality of protruding walls substantially parallel to each other are disposed on one of an upper surface of the transparent plate, a lower surface of the transparent plate and an upper surface of the planar light source. The protruding walls may be either I-shaped, L-shaped, U-shaped or square-shaped. When the protruding walls are made of an opaque material, the protruding walls can effectively reduce the intensity of the halo light surrounding a transparent keycap. When the protruding walls are made of a transparent material with a designated color, the halo light surrounding the keycap will be modulated with the designated color. | 06-30-2016 |
