Abstract: A QLED light-emitting device is provided, including a first electrode layer, an electron injection layer, an electron transport layer, a light-emitting layer, a hole transport layer, a hole injection layer, and a second electrode layer. Wherein, the light-emitting layer includes a plurality of quantum dot layers disposed in a stack, and insulating layers are disposed among the quantum dot layers adjacent to one side of the electron injection layer. Through disposing the insulating layers among the quantum dot layers adjacent to the one side of the electron injection layer, an electron transmission rate is reduced, thereby balancing the electron transmission rate and a hole transmission rate and improving luminous efficiency of QLEDs.

Abstract: Please replace Abstract with the following amended Abstract: A reference voltage generation circuit is provided. The reference voltage generation circuit reduces a potential difference between a reference voltage less than a first data driving voltage and a data driving voltage, namely, the potential difference between a lower reference voltage and the data driving voltage is reduced. Therefore, the power loss of a voltage dividing module is reduced to prevent the problems of reduced reliability and reduced service life of a drive circuit board due to excessive internal temperature.

Abstract: The present application provides a light sensor and a display device. A light sensing transistor and a switching transistor in the light sensor are configured to form a light sensor circuit. In a structural design, amorphous silicon is configured as a first active pattern of the light sensing transistor, so that a thickness of a channel region of the first active pattern is greater than or equal to 5000 angstroms. Therefore, a number of photo-generated carriers of the light sensing transistor is increased, which makes the light sensor have higher responses and increases fingerprint or palmprint recognition success rates.
