Abstract: The embodiments of the present disclosure provide an electrode plate, an electrolysis apparatus, and a laundry treatment device. Multiple through holes penetrating the electrode plate in the thickness direction of the electrode plate are formed in the electrode plate. The density of the through holes in the electrode plate is 1-10/cm2. According to the electrode plate in the embodiments of the present disclosure, on the one hand, because the density of surface charge at the junction of the inner wall of the through hole and the surface of the electrode plate is larger, and the electric field intensity nearby is higher, the electrolysis efficiency can be greatly improved, more active substances such as hydroxyl radicals and active chlorine can be generated, and more microbubbles can also be generated, which can improve the sterilization, cross color prevention and washing effects.

Abstract: A wafer level packaging structure of a high-pixel image sensor chip comprises an image sensor chip, a supporting substrate and a light-transmitting substrate, the image sensor chip comprises a base, a sensing region formed on a first surface of the base; the supporting substrate is attached to the first surface of the base and provided with a first opening penetrating through the supporting substrate at a position corresponding to the sensing region, and the sensing region is exposed from a bottom of the first opening; and the light-transmitting substrate is fixed on a first surface plane of the supporting substrate and covers a top of the first opening, and two surface planes of the light-transmitting substrate are parallel with a plane on which the sensing region is located.
