Abstract: The invention provides an electroluminescent display screen and a method for preparing the same, and a display device, by which an electroluminescent display screen can automatically screen the irradiation of a laser, so that a mask can be omitted, the requirement on the manufacture process can be lowered, the production cost can be reduced, and the production capacity can be increased. An electroluminescent display screen according to the invention includes: a back plane; a package substrate; and a luminescent layer and a frit sealant provided between the back plane and the package substrate. The electroluminescent display screen further comprises a light-shielding pattern layer for shielding the region other than the frit sealant when a laser irradiates on the frit sealant, which is formed on one side of the package substrate that faces the back plane.

Abstract: A display substrate and a driving method thereof, and a display apparatus are provide. The display substrate includes an array of a plurality of sub-pixels having at least two colors, wherein the sub-pixels of each color constitute a plurality of sub-pixel sets, each of the sub-pixel sets includes at least two sub-pixels of the same color and arranged adjacently in a first direction, and sub-pixel sets of different colors are arranged alternately in the first direction. The display substrate may be applied to display devices, particularly to organic light emitting diode display devices using different organic light emitting layer materials for different sub-pixels.

Abstract: A battery identification system and method for an electronic device, and an electronic device are disclosed. A Hall sensor is set in the electronic device, and a magnetic induction component is set in a first-capacity battery, wherein, when the first-capacity battery is in an installation position, the magnetic induction component is in a sensing area of the Hall sensor; and when the first-capacity battery is installed in the electronic device, the Hall sensor senses approach of the magnetic induction component, and outputs a control signal used for identifying the first-capacity battery. With a Hall sensor switch and a magnetic component in the battery, batteries with different capacities used in the electronic device can be identified.

Abstract: A flush valve system may comprise a rail guide configured to extend between upper and lower portions of the flush valve system in a toilet tank. A float may be slidably coupled to the rail guide and be configured to be received by a reservoir associated with the float. The float may comprise a closed upper surface with a mating pocket and one or more circumferential walls extending from the closed upper surface. A lock mechanism may be slidably received by the mating pocket of the float. The lock mechanism may comprise one or more bias arms to fixedly engage the lock mechanism to the float and one or more locking members to fixedly engage the lock mechanism to the rail guide.

Abstract: An improved flush system as described herein may comprise a reservoir with a drain opening for egress of liquids disposed in the reservoir into a surrounding toilet tank. A lock mechanism is slidably received by the reservoir so that the lock mechanism is translatable between one or more fixed positions on the reservoir. In turn, translating the lock mechanism into the reservoir at increasing depths causes a size of the drain opening to be reduced and therefore adjusted.
