Keyboard with improved backlight module for key structures
A recently granted patent (Publication Number: US11967472B2) discloses a novel keyboard design featuring a backlight module with a light source, reflective layer, light guide layer, and shielding layer. The light guide layer includes a through-hole, with the reflective layer and shielding layer in contact through this hole. The keyboard also includes a base plate with a positioning portion corresponding to the through-hole, a membrane circuit, and key structures. Various embodiments of the keyboard involve fixing members, reflective extension portions, and shielding extension portions to enhance the functionality and structure of the keyboard.
Furthermore, the patent describes a keyboard with a backlight module, base plate, membrane circuit, and key structures. The positioning portion of the base plate protrudes towards the membrane circuit and includes a recess facing the backlight module. The reflective layer features a reflective extension portion that extends to the through-hole of the light guide layer, enhancing the interaction between components. Fixing members are utilized to secure the reflective extension portion, positioning portion, and membrane circuit, ensuring stability and functionality. Additionally, the design includes features such as exposed extension portions and connecting portions for efficient operation and assembly of the keyboard.
