  • Patent number: 11308859
    Abstract: A shift register circuit and a method of driving the same, a gate driver circuit, an array substrate and a display device. The shift register circuit includes an input subcircuit and a signal output subcircuit. The input subcircuit includes: a control module, which is configured to output a signal of the first voltage terminal to a voltage dividing node under a control of an input signal; an input module configured to output a signal of the voltage dividing node to the signal output subcircuit under a control of the control module; and a voltage dividing module, a resistance value of the voltage dividing module having a negative relationship with a temperature, and the signal output subcircuit is connected with an output terminal of the input module and configured to output a gate scan signal from an output signal terminal under a control of the input module.

  • Patent number: 11270096
    Abstract: Systems and methods for through-display imaging. An optical imaging sensor is positioned at least partially behind a display and is configured to emit shortwave infrared light at least partially through the display to illuminate an object, such as a fingerprint, in contact with an outer surface of the display. Surface reflections from the object are received and an image of the object can be assembled.
