摘要:
Provided are an ionic liquid and a method of preparing the same. The ionic liquid includes at least one type of compound represented by (Cat+)(R′COO−). Here, the Cat+ is a cation selected from the group consisting of quaternary ammonium, quaternary phosphonium, sulfonium, imidazolium, pyridinium, pyrazolium, piperidinium, pyrrolium, pyrrolidinium, triazolium, and a mixture of two or more thereof, and R′ is a hydrocarbon comprising at least one unsaturated bond, and having 4 to 30 carbon atoms. The ionic liquid is partially or completely miscible with various polar and/or non-polar solvents, and may be used as a solvent, a solvent additive, an electrolyte, a heat carrier, a charge carrier, a heat carrier additive, a charge career additive, or a phase transfer catalyst, at room temperatures and below. Furthermore, the cost of manufacturing the ionic liquid can be reduced.

A backlight assembly and an LCD device containing the same include a plurality of light source modules containing sequentially arranged red, green, green, blue and red LEDs. The backlight assembly can improve color realization ratio and light efficiency in an LCD device by uniform illumination of an LCD panel with color-mixed white-color light.
摘要:
An assembly of prefabricated panels, which may be attached to outer and inner walls of buildings, is disclosed. The assembly includes mounting brackets and a plurality of prefabricated panels. Each of the prefabricated panels has a panel body, a bent section extending from an upper end of the panel body to define at least a portion of a coupling recess, and an engagement protrusion downwardly protruded from a lower end of the bent section to engage the mounting brackets, thereby allowing the prefabricated panels to be supported by the mounting brackets. Each of the prefabricated panels further includes a lower bent section extending from a rear surface of the panel body near a lower end of the panel body such that the lower bent section of an upper one of the prefabricated panels is fitted in the coupling recess of a lower one of the prefabricated panels when the prefabricated panels are coupled together.
摘要:
A lamp electrode includes a sealed tube for generating light when powered by an external power supply and a pair of electrodes formed on the ends of the sealed tube. Solder is filled into the space between each electrode and the sealed tube, and formed on the surface of the exterior surface of the electrodes. A method for forming the lamp electrode includes forming a cylindrically shaped electrode on an end of a sealed tube; maintaining a supply of solder in the liquid state; and dipping the end of the tube on which the electrode is formed into the solder.
摘要:
An organic light-emitting display device and a method of fabricating the same is disclosed, to prevent contact defects, the organic light-emitting display device comprising a first substrate formed a sub-pixel driving array; a second substrate formed an OLED array; a sealant to bond the first and second substrates to each other; and a conductive material deformed when bonding the first and second substrates to each other so as to electrically connect the sub-pixel driving array and the OLED array to each other, the conductive material formed on the sub-pixel driving array.
摘要:
A mobile terminal supporting detachable memory cards and a method for managing the detachable memory cards attached to the mobile terminal is provided. The detachable memory card management method of the present invention includes displaying, if at least two memory cards are detected, icons representing the memory cards on an idle mode screen, detecting selection of at least one of the icons, and creating files, stored in a source memory card represented by one of the selected icons, in a destination memory card represented by another icon. The detachable memory card management method of the present invention is capable of displaying the card icons representing the memory cards attached to the mobile terminal on the idle mode screen such that the user can identify the attached memory cards.
