Latest Patents

Park is credited with 1 patent: “Pixel circuit, display device including the same and electronic device including the same.” The invention describes a pixel circuit with a light emitter, including an emission-driving transistor that supplies driving current based on a data voltage, and a write transistor that applies the data voltage in response to a write-gate signal. A light-emitting element emits light based on that current.

The circuit also includes a light sensor. Its sensing-driving transistor receives a reset voltage and sensing voltage at one control electrode and an adjustable photodiode voltage at another, generating a sensing current in response to the sensing voltage. Sensing-initialization and sensing-output transistors control the application of the reset voltage and the delivery of sensing current to a sensing line.
