Abstract: The present disclosure provides an adapter circuit including a bus capacitor, a PMOS power transistor, and a sampling control module; a positive terminal of the bus capacitor is connected to a DC bus voltage, and a negative terminal of the bus capacitor is connected to a drain of the PMOS power transistor; a gate of the PMOS power transistor is connected to a drive signal, and a source of the PMOS power transistor is grounded; the sampling control module is used to obtain the drive signal by detecting an AC mains input voltage and a power-down voltage when the bus discharges, so as to turn off the PMOS power transistor after the AC mains input voltage reaches a peak value, and turn on the PMOS power transistor after the power-down voltage reaches a set voltage; the drive signal includes a PMOS Turn-on signal and a PMOS Turn-off signal.

Abstract: The present disclosure relates to the technical field of display and discloses a polarizer, a display panel and a display device, where the polarizer includes two layers of protective films, as well as one layer of main polarizing film and at least one layer of auxiliary polarizing film between the two layers of protective films, and a set angular difference exists between an angle of a transmittance axis of the auxiliary polarizing film and an angle of a transmittance axis of the main polarizing film.

Abstract: The present disclosure provides a display device, including: a display panel including a first substrate and a second substrate arranged opposite to each other to form a cell, the display panel being provided with a bonding side, and the first substrate extending beyond the second substrate at the bonding side to form a bonding region on the first substrate; a first polarizer arranged at a side of the first substrate away from the second substrate; and a second polarizer arranged at a side of the second substrate away from the first substrate. An edge of the second polarizer extends beyond an edge of the second substrate at the bonding side of the display panel, a gap is formed between a portion of the edge of the second polarizer extending beyond the edge of the second substrate and the bonding region on the first substrate, and a filler is arranged in the gap.
