Abstract: A gate electrode and a method for manufacturing the same, and a method for manufacturing an array substrate are provided. The method for manufacturing a gate electrode may include: providing a substrate, wherein the substrate includes a gate electrode region and a non-gate electrode region; and forming a gate electrode layer on the substrate, wherein the gate electrode layer includes a conductive portion corresponding to the gate electrode region and a transparent portion corresponding to the non-gate electrode region. According to the gate electrode and the method for manufacturing the same, and the method for manufacturing an array substrate, step difference can be eliminated, thereby avoiding an influence of the step difference on the crystallization property of a polysilicon material when an Excimer Laser Annealing (ELA) process is performed on the amorphous silicon layer, and obtaining a better crystallization effect.

Abstract: The embodiments of this disclosure provide a luminescent complex, a luminescent material, a substrate for display and a production method thereof, and a display apparatus. This disclosure relates to the technical field of display. It is possible to increase the dispersibility of the luminescent particles, such as quantum dots or the like in the main material of a color filter to solve problems, such as uneven light emission, low light emission efficiency or the like of a substrate for display comprising the luminescent particles, so as to further reduce the loss of the back light brightness. This luminescent complex comprises a luminescent particle; an organic ligand attached to the surface of the luminescent particle; group A in the structural formula of the organic ligand is a binding group which binds to the luminescent particle; and in the structural formula of the organic ligand, the carbon-carbon double bond which is attached to the X1 group, the X2 group and the X3 group may be subjected to a crosslinking reaction with a photosensitive resin under an exposure condition. This disclosure further provides a luminescent material which is used for the luminescent complex and comprises the luminescent complex, a substrate for display comprising this luminescent material, and a production method of a display apparatus.

Abstract: A display panel includes a first substrate and a second substrate which are arranged opposed to each other. The space between the first substrate and the second substrate is separated into a plurality of sub-pixel regions. Within each sub pixel region, a first electrode, a first fluid layer, a second fluid layer, a hydrophobic dielectric layer and a second electrode are arranged in this order. The first fluid layer is made of hydrophilic liquid. The second fluid layer is made of ink. When no electric field is applied between the first electrode and the second electrode, the ink spreads over the surface of the hydrophobic dielectric layer. When an electric field is applied between the first electrode and the second electrode, the ink aggregates to expose the hydrophobic dielectric layer.

Abstract: An imprint template includes a first region and a second region located in the periphery of the first region. The first region is provided with a first imprint structure configured to imprint a first film layer pattern into a base material in a product region of a target substrate. The second region is provided with a second imprint structure configured to imprint a second film layer pattern into the base material in the periphery of the product region of the target substrate. And the second film layer pattern is used for assessing imprint quality of the first film layer pattern.
