Latest Patents
One of his latest patents is a capacitive fingerprint sensing apparatus. This apparatus includes sensing electrodes, a sensing driver, and a processing module. Under a first self-capacitive sensing mode, the sensing driver combines M adjacent sensing electrodes to form a first sensing electrode set to perform a first self-capacitive sensing to obtain a first self-capacitive fingerprint sensing signal. Under a second self-capacitive sensing mode, the sensing driver combines N adjacent sensing electrodes to form a second sensing electrode set to perform a second self-capacitive sensing to obtain a second self-capacitive fingerprint sensing signal. The processing module generates a first self-capacitive fingerprint pattern and a second self-capacitive fingerprint pattern according to the sensing signals and combines them into a third self-capacitive fingerprint pattern.
Another notable patent is for an in-cell touch panel and its trace layout. This in-cell touch panel includes a plurality of pixels, each with a laminated structure that consists of a substrate, a TFT layer, a liquid crystal layer, a color filter layer, and a
