Latest Patents

Among his latest patents is a display device that includes a readout circuit designed to output a fingerprint sensing signal. This innovative display device comprises a display panel, a scan driver, a panel driving circuit, and a readout circuit. The display panel features a pixel that incorporates a light-emitting element and a sensor with a light-sensing element. The scan driver is responsible for outputting a scan signal to drive both the pixel and the sensor in response to a scan control signal. The panel driving circuit generates this scan control signal, while the readout circuit produces switching signals based on the scan control signal and outputs a fingerprint sensing signal corresponding to the sensing signal received from the sensor.

Another notable patent involves a display panel that has an input sensing function. This display panel consists of multiple light-emitting pixels that emit light in response to a first scan signal, a second scan signal, and a light emission control signal. Additionally, it includes several light-sensing pixels that output a sensing signal corresponding to external light in response to the first and second scan signals. Each light-emitting pixel features an organic light-emitting diode, while each light-sensing pixel includes an organic photodiode, which is electrically connected to the cathode of the organic light-emitting diode.
