  • Publication number: 20170097650
    Abstract: An adaptive voltage source, comprising a signal output end, and a reference resistance forming circuit and a sensing module connected in series between a voltage source and a low power level; the sensing module comprises a sensing end coupled to a transistor to be sensed to sense the threshold voltage drift of the transistor to be sensed in a device circuit; the equivalent resistance of the sensing module increases with the increase of the sensed threshold voltage drift; and the signal output end is coupled to a first node coupled to the reference resistance forming circuit and the sensing module, and is used to output adaptive voltage. The output adaptive voltage is adjusted via the threshold voltage drift sensed by the sensing module. Based on the circuit, also disclosed are a shift register and unit thereof, and display.

    Abstract: An ultraviolet light sensing circuit and sensing system. The ultraviolet light sensing circuit comprises a modulation unit and a phase delay unit, wherein the modulation unit comprises a first stage of inverter which is used for sensing ultraviolet light and is used as a voltage feedback modulation stage; and the phase delay unit comprises N stages of inverters which are connected in sequence, where N is an even number which is greater than or equal to 2. The modulation unit is connected to the phase delay unit in sequence, and the output voltage of the phase delay unit is fed to the modulation unit; and the modulation unit is modulated by a control signal which is a pulse signal. The ultraviolet light sensing circuit and sensing system can be used for ultraviolet light information communications. The ultraviolet light sensing circuit can sense ultraviolet light signals and output amplitude modulation wave signals.
