Various embodiments of the disclosure relate to, e.g., a case of a wearable electronic device wearable on a human body portion. According to certain embodiments of the disclosure, there may be provided an electronic device case for storing a wearable electronic device comprising a case housing forming a space for receiving the wearable electronic device, a conductive supporting member disposed in the case housing, and a contact member disposed in the space for receiving the wearable electronic device and exposed to an exterior when the case housing is opened, electrically connected with the conductive supporting member, and configured to at least partially contact a conductive portion of the wearable electronic device. Other various embodiments are also possible.

A display device has an anti-static layer extending from a cover member along a side surface of a display panel to an inner surface of a hole of a cushion plate. Thus, a contact area between the anti-static layer and the display panel may be increased, thereby reducing a brighter phenomenon and a greenish phenomenon at a distal end of the display panel.

A space-saving configuration for electronics is disclosed in which at least four circuit boards are arranged to form sides of a five-or-greater sided geometric prism that are perpendicular to a common plane. That is, they are stood up on their sides and connected with flex cable to approximate a cylinder. Each circuit board can include one or more sides with electrical components. The circuit boards make up at least half of the five-or-greater sided geometric prism such that the circuit boards wrap at least halfway around. A common connector on one of the circuit boards can be configured to receive power from an underlying motherboard, and flex cables connecting adjacent circuit boards in series distribute power received from the connector to each of the circuit boards in series.

A driving circuit includes at least one first module, an electrostatic charge/discharge module connected to the first module and a grounding module; each first module includes a driving module, a signal transmission module and a gating module; the signal transmission module is connected to and transmits a driving signal to the driving module; the grounding module is grounded; the gating module is connected with the signal transmission module; the gating module is turned on with its turn-on voltage less than or equal to a voltage of the signal transmission module, or turned off with the turn-on voltage greater than the voltage of the signal transmission module; the turn-on voltage of the gating module is greater than that of the driving module; the charge/discharge module is connected to the gating module and the grounding module, and configured to store charges flowing therethrough and release the charges to the grounding module.

A solid state drive apparatus includes a case including a base and side walls extending upward along a circumference of the base, an electrostatic prevention structure of a metal pillar spaced apart from the side walls and protruding from at least a partial surface of the base and an electrostatic absorbing member on at least a partial surface of the metal pillar, a package substrate module mounted on the electrostatic prevention structure in the case, and a cover covering the case and the package substrate module.

A driving circuit includes at least one first module, an electrostatic charge/discharge module connected to the first module and a grounding module; each first module includes a driving module, a signal transmission module and a gating module; the signal transmission module is connected to and transmits a driving signal to the driving module; the grounding module is grounded; the gating module is connected with the signal transmission module; the gating module is turned on with its turn-on voltage less than or equal to a voltage of the signal transmission module, or turned off with the turn-on voltage greater than the voltage of the signal transmission module; the turn-on voltage of the gating module is greater than that of the driving module; the charge/discharge module is connected to the gating module and the grounding module, and configured to store charges flowing therethrough and release the charges to the grounding module.

An electronic component includes a case body, an electronic circuit, and a conductor portion. The case body is formed by fitting a first housing and a second housing. The electronic circuit board is accommodated in the case body. The conductor portion is formed to continuously extend in a circumferential direction of the electronic circuit board at a portion of the first housing where the first housing is fitted to the second housing. The conductor portion is electrically connected to a ground of the electronic circuit board.

A display apparatus includes an antistatic coating disposed sequentially on the cover member, the display panel and the cushion plate, wherein the antistatic coating is configured to include a plurality of rod-shaped nanowires, thereby improving conductivity of the antistatic coating and effectively reducing a brightening phenomenon where light emission gets brighter at an end or on a side than other areas of the display panel.

A display panel includes a cover window, an ink layer formed with a multi-layer structure on a rear surface of the cover window and directly adhered to a middle frame, and an adhesive layer disposed on the rear surface of the cover window and overlapping with the ink layer, and at least one layer of the multi-layer structure of the ink layer may include a conductive material. An electric charge generated by the cover window is distributed to the middle frame via the ink layer and discharged by the middle frame to prevent a shift phenomenon, a green phenomenon, or both in the display panel.

An air stream controller and a system for static charge reduction comprising such air stream controller are disclosed. The air stream controller comprises an enclosed hollow body having a first surface and a second surface, wherein, an opening is on the first surface facing an incoming tubing of a device for static charge reduction for receiving air stream from the device for static charge reduction, wherein an outgoing tubing of the device for static charge reduction is attached onto the second surface of the enclosed hollow body for discharging the air stream. A technical solution to more effectively prevent the “leaking of air stream passage” can be achieved through the design of a multi-holes structure at the air passage to more broadly expand its air sucking area coverage without increasing the original suction power.
