Abstract: A luminous keyboard includes a key module, a light guide plate, a top-view light-emitting element and a light-shading element. The top-view light-emitting element emits a light beam. The light guide plate is located under the key module. The top-view light-emitting element is located under the light guide plate. A light-outputting surface of the top-view light-emitting element is contacted with the light guide plate. The light-shading element is disposed on the light guide plate for shading the light beam. A portion of the light-shading element is inserted into the light guide plate opening and formed as a reflective part in the light guide plate opening. After the light beam is projected on the reflective part and reflected by the reflective part, the light beam is transferred within the light guide plate and projected to the key module.

Abstract: A keyboard device includes a key switch, a base plate, a connecting element and a replaceable key. The replaceable key includes a coupling plate and a keycap. The connecting element is connected between the coupling plate and the base plate. The coupling plate includes a first sliding part. The keycap includes a second sliding part. When the second sliding part is slid relative to the first sliding part, the keycap is combined with the coupling plate or the keycap is detached from the coupling plate. Consequently, the keycap is easily assembled or disassembled. Moreover, since the connecting element is not touched during the process of disassembling the keycap, the connecting element is not damaged.

Abstract: The present invention provides a luminous keyboard, including: at least one key cap; a support plate; a support component, connected to the key cap and the support plate and capable of guiding the key cap to vertically move relative to the support plate; a thin film circuit board, disposed on the support plate; at least one light emitting component, configured to emit a light ray to the key cap; and a shield, covering the light emitting component, where there is a gap between the shield and the light emitting component, and the shield is provided with a diffraction grating at a position where the light ray passes through the shield.

Abstract: The present invention provides a backlight structure, including: a light source module having a first slant surface, where a slot is provided on the first slant surface, and the slot is configured to accommodate a light emitting element; a light guiding module having a light guiding plate and a light shielding layer, where a second slant surface is provided at a side of the light guiding module; and a baseplate configured to bear the light guiding module and the light source module. The light source module is engaged with the second slant surface of the light guiding module by means of the first slant surface.

Abstract: A keyboard device includes a base plate, a connecting element and a keycap. The connecting element is connected with a hook of the keycap and the base plate. The keycap includes an elastic structure, a first hooking part and a second hooking part. The elastic structure hook is installed on an inner surface of the keycap. The first hooking part is arranged beside a first side of the elastic structure. The second hooking part is arranged beside a second side of the elastic structure. While the connecting element is assembled with the keycap, the first hooking part and the second hooking part are pushed by the connecting element and the keycap is bent in response to the elasticity of the elastic structure. Consequently, the first hooking part is moved away from the second hooking part.

Abstract: A luminous keyboard includes an illumination module, a keycap and plural light-guiding structures. The illumination module generates a light beam. The keycap includes a character/symbol region. The plural light-guiding structures are disposed on a bottom surface of the specified keycap and aligned with the character/symbol region. The light beam to be projected to the specified keycap is guided to the character/symbol region by the light-guiding structures. The light-guiding structures of the luminous keyboard are arranged according to the layout of the character/symbol regions in different countries. It is not necessary to change the light-guiding structures of the light guide plate according to the layout of the character/symbol regions of different countries.

Abstract: The present invention relates to a keyboard, including: a key, a switch circuit board, and a base plate, and the key includes a keycap and a balance bar. The keycap includes a first hook and a second hook, and the first hook is disposed on an inner surface of the keycap and is located on an outer side of the keycap. The second hook is disposed on the inner surface of the keycap and is located in a central area of the keycap. The balance bar is disposed below the keycap and is fastened in a first opening of the first hook and a second opening of the second hook. The first opening has a round shape, and the second opening has an elliptic shape.

Abstract: The present invention provides a backlight keyboard with a backlight adjusting function, a backlight adjusting system and a backlight adjusting method. The backlight keyboard includes plural keys and a backlight module. The backlight module includes a light guide plate and plural light-emitting elements. The backlight adjusting method includes the following steps. Firstly, the plural light-emitting elements emit light beams, so that plural backlight zones corresponding to the plural keys are formed on the light guide plate. Then, respective luminance values of the plural backlight zones are detected. Then, an overall average luminance value of the plural backlight zones is calculated. If a preset criterion is satisfied, brightness levels of the light-emitting elements corresponding to the backlight zones are adjusted according to the luminance value of the backlight zones and the overall average luminance value.
