A quantum dot optical function panel and its preparation method comprises a functional layer, a condensation layer and a diffusion layer which compose a multilayer structure. Said functional layer is located between condensation layer and diffusion layer. The functional layer comprises a main layer and quantum dots uniformly distributed in main layer. Said condensation layer comprises a condensation substrate layer and condensation bulges distributed over the upper surface of condensation substrate layer. Said diffusion layer comprises a diffusion substrate layer and diffusion bulges distributed over the lower surface of diffusion substrate layer. The condensation layer and diffusion layer of the quantum dot optical function panel of the present invention can resist oxygen and water vapor to a certain extent, protecting the quantum dots well.

Quantum dot optical function panel

The present invention provides a charging system and a charging circuit thereof, including a circuit of a charging apparatus and a circuit of a wireless portable electronic device capable of recognizing an electric connection relationship with the charging apparatus.

Charging system and charging circuit thereof

A power-on reset circuit includes a first circuit and a second circuit. The first circuit include a first NMOS transistor having a gate controlled by a low voltage supply VDD_L, a resistor connected between the source of the first NMOS transistor and a voltage supply VSS that is lower than VDD_L, and one or more diodes serially connected between a high voltage supply VDD_H and the drain of the first NMOS transistor. The second circuit includes a first PMOS transistor having a source connected to VDD_L, a second PMOS transistor having a source connected to the drain of first PMOS transistor, a second NMOS transistor connected between the drain of the second PMOS transistor and VSS, and an inverter configured to output a signal in response to the power on of the high voltage supply VDD_H and the low voltage supply VDD_L.
