Abstract: Disclosed are a protective coating composition for an electronic board and a method for preparing the same. The protective coating composition includes urethane-modified alkyd resins that can prevent poor grounding caused by low molecular weight siloxanes generated in a conventional silicone-type coating compositions and preventing performance degradation caused by tin whisker growth while lowering emissions of volatile organic compounds (VOCs).

Abstract: Disclosed are an epoxy coating composition for protection of electronic circuit boards and a preparation method thereof to improve the reliability and durability of the electronic circuit board. The epoxy coating composition includes an amount of about 35 to 70 wt % of a modified epoxy resin including a fatty acid-acrylic epoxy resin, an amount of about 30 to 65 wt % of a first solvent, an amount of about 0.1 to 1.2 wt % of a metal catalyst, an amount of about 0.05 to 0.45 wt % of a defoamer, and an amount of about 0.1 to 0.5 wt % of a surface conditioner, based on the total weight of the epoxy coating composition. The fatty acid-acrylic epoxy resin is prepared by polymerizing a reactant that is obtained by a reaction between an epoxy resin mixture and an unsaturated fatty acid with an acrylic resin using a polymerization catalyst.

Abstract: Disclosed is a light emitting display device including a substrate on which first to third sub-pixels are provided, and first to third light emitting devices that are respectively provided in the first to third sub-pixels to emit light of different wavelengths. The first to third light emitting devices each include first to third intermediate layers between a first electrode and a second electrode that face each other. The first to third intermediate layers include a red light emitting layer, a green light emitting layer, and a blue light emitting layer in order on the first electrode, in which the blue light emitting layer of the first intermediate layer has a vertical phase higher than those of the blue light emitting layers of the second and third intermediate layers.

Abstract: A display device can include a first sub light-emitting element, a second sub light-emitting element and a third sub light-emitting element. The first sub light-emitting element includes a 1-1 hole transport layer, a 1-2 hole transport layer disposed on the 1-1 hole transport layer, and a first organic light-emitting layer disposed on the 1-2 hole transport layer. The second sub light-emitting element includes a 2-1 hole transport layer, a 2-2 hole transport layer disposed on the 2-1 hole transport layer, and a second organic light-emitting layer disposed on the 2-2 hole transport layer. The third sub light-emitting element includes a 3-1 hole transport layer, a 3-2 hole transport layer disposed on the 3-1 hole transport layer, and a third organic light-emitting layer disposed on the 3-2 hole transport layer.

Abstract: A display device can include a display panel having a first display area in which first pixels are disposed, and a second display area in which second pixels and a light-transmission area disposed between the second pixels are disposed, and a sensor disposed to correspond to the second display area. One of the second pixels includes sub-pixels. The display panel can include a circuit layer, a light emitting element layer disposed on the circuit layer, and an anti-reflection layer disposed between a planarization layer of the circuit layer and an anode electrode of the light emitting element layer. Further, a space is formed between an anode electrode of one sub-pixel and an anode electrode of another adjacent sub-pixel, and a path of light directed to the sensor through the space is changed by the anti-reflection layer. Accordingly, the display device can minimize the amount of light reaching the sensor.

Abstract: A prefabricated tuned top and a launcher for launching the tuned top, manufactured in a small size with five components of a knob, a rim, beads, a body and a spinning spindle. The tuned top can be readily assembled by sequentially inserting and then tightening the components. The tuned top implements a changeable spinning form based on induction of a change in difference between the centripetal force and centrifugal force, generated during spinning, since the center of gravity can be eccentrically disposed freely according to the user's selection. The tuned top is prevented from being reversely loosened so it can be safely, semi-permanently, and easily enjoyable at any location. The tuned top enables accurate and stable mounting when a launcher is used, such that the top is not easily separated therefrom but is quickly launched without a launch failure, thereby providing accurate launching without the loss of spinning power.
