OLED Film Keyboard Keycap Illumination Uniformity

The patent divides the illumination system into multiple independent OLED segments, with each OLED located at a specific key position. This segmentation eliminates hotspots by providing localized illumination and reduces overall power consumption compared to a single high-power light source, as each OLED only illuminates its specific key area.

Each key position receives customized illumination from its dedicated OLED, allowing different brightness levels and illumination characteristics for different keys. This local quality approach ensures uniform illumination across all keys while minimizing energy waste, as each OLED operates independently at optimal power levels.

The keyboard is segmented into multiple independent key units, each with its own OLED. This segmentation achieves uniform illumination across the keyboard while the modular nature of the segmentation allows for straightforward manufacturing and assembly, mitigating the complexity increase.

The OLED is integrated directly into the key structure, merging the illumination function with the keycap design. This integration eliminates the need for separate diffraction elements and light distribution mechanisms, achieving uniform illumination without proportionally increasing overall device complexity.

By segmenting the illumination into multiple low-power OLEDs distributed across the keyboard, the system achieves uniform illumination without the high power consumption of a single centralized light source. Each OLED operates at low power while collectively providing evenly distributed lighting.

Each OLED serves its own key position directly, eliminating the need for complex light distribution systems and diffraction elements required by conventional light sources. This self-service approach reduces power consumption while ensuring uniform illumination, as each OLED naturally illuminates its local area without requiring additional optical components.
