Abstract: The present application relates to a quantum dot ink, a quantum dot layer patterning method, and a quantum dot optoelectronic device. The quantum dot ink contains a quantum dot material; a cross-linking agent and a photoacid generator, wherein the quantum dot material comprises quantum dots and an organic ligand on surfaces of the quantum dots, the organic ligand comprises a crosslinking unit and a coordination functional group coordinated with the quantum dots, the crosslinking unit in the organic ligand can be subjected to a cross-linking reaction with a polyhydroxy compound cross-linking agent under the catalysis of hydrogen ions generated via the photoacid generator under ultraviolet irradiation. By means of the quantum dot ink, since photocrosslinking molecules directly participate in patterning of a quantum dot layer, there is no need to wash away a photoresist sacrificial layer compared to existing photoresist patterning methods, so that the process flow is greatly simplified.

Abstract: Embodiments relate to type-I PLLs that do not lock at a sub-harmonic frequency of a reference clock signal by controlling timing of charging or discharging of one or more capacitors in the PLLs. A phase frequency detector (PFD) of a type-I PLL can prevent sub-harmonic locking by generating a clear output signal to cause a sampling capacitor of PLL's loop filter to discharge only during a time period when the sampling capacitor is not being charged. For example, the PFD can include a gating element to control the time during which the clear output signal is generated. By ensuring that the sampling capacitor is not discharged during a time period while it is being charged, the PLL's voltage-controlled oscillator is controlled to oscillate at an intended frequency rather than at a sub-harmonic of the intended frequency.
