Latest Patents

One of Yu Hao Kao's latest patents is focused on a proximity sensor that includes devices, methods, and systems for detecting proximity. This invention features a first light emitter that emits light for a first time period while a light detector is not sensing. A second light emitter emits light for a second time period while the light detector is sensing. In certain implementations, the first light emitter directly illuminates the light detector during the first time period, while the second light emitter is obstructed from directly illuminating the light detector during the second time period. Additionally, the first light emitter may be obstructed from illuminating a display during the first time period, and the second light emitter may be obstructed from directly illuminating the light detector during the second time period. The first light emitter is designed to emit light during the first time period in such a way that the light detector maintains a linear responsivity during the second time period.

Another notable patent involves under-display sensors, systems, and methods. This invention includes a display device and a method for operating the display device, which involves transmitting a proximity signal from a proximity sensor positioned under a lower surface of a surface layer. An illumination component is positioned between the surface layer and the proximity sensor. In response to the illumination component being deactivated, the system receives a reflected proximity signal based on the proximity signal. It then determines a proximity value based on the reflected proximity signal and modifies the operation of the display device accordingly. This modification can include activating or deactivating the illumination component or altering its properties.
