Abstract: User expectations demand that keypad layout and size, as well as keypad performance and illumination remain the same or improve over time. In various implementations, the keyboards disclosed and detailed herein incorporate an array of thermoset bare die light emitting diodes in an effort to more evenly distribute light through a keyboard structure without increasing keyboard thickness, as compared to prior art designs.
