Abstract: A display device includes a substrate and a plurality of unit pixels disposed on the substrate. Each unit pixel includes a plurality of sub-pixels, a plurality of light sensing pixels, and a plurality of partition wall members. Each of the sub-pixels includes a light emitting element that emits light and a light emitting area from which the light is emitted. Each of the light sensing pixels includes a light receiving element that outputs a sensing signal corresponding to the light and a light receiving area that receives the light. In a plan view, each of the partition wall members surrounds the corresponding light receiving area and overlaps at least some of the sub-pixels.

Abstract: A display device includes a substrate having a first main display area, a second main display area, and a sub-display area positioned between the first main display area and the second main display area; a first driving circuit positioned on the sub-display area of the substrate; a first sub-pixel circuit and a second sub-pixel circuit positioned on respective sides of the first driving circuit in the sub-display area of the substrate; a first sub-light-emitting device connected to the first sub-pixel circuit and overlapping the first driving circuit; and a second sub-light-emitting device connected to the second sub-pixel circuit and overlapping the first driving circuit.

Abstract: A speaker device for a mobile terminal enlarges resonance space of a speaker while decreasing a size of the mobile terminal. The speaker device for a mobile terminal includes at least one speaker installed within a main body of the mobile terminal and a speaker bracket installed at one surface of an electronic circuit board mounted within the main body. In addition, the speaker bracket fixes the at least one speaker in place and has housing space to enclose the at least one speaker therein. At least one resonance groove is formed in a portion enclosed by the speaker bracket in one surface of the electronic circuit board. Because resonance space can be enlarged without increasing a size of the speaker bracket, an entire thickness of the mobile terminal can be reduced and thus a size and thickness of the mobile terminal can be decreased.

Abstract: A universal serial bus (USB) dongle device and method support a connection to a dongle expanded device to perform high speed and multiple communications while observing a USB standard form. The USB dongle device includes a body and a plug formed in an edge of one side of the body. The plug includes a basic connection unit corresponding to a USB basic connection port and an expansion connection unit surrounding the basic connection unit, in which at least one signal line is formed.

Abstract: A mobile phone charger with a sterilization function. The mobile phone charger includes a charging current generator and a sterilizer. The charging current generator generates a charging current to charge the battery of the mobile phone upon receiving an input current, and selectively generates the charging current upon receiving a charging initiation signal. The sterilizer is driven by the charging current received from the charging current generator, and sterilizes the battery and the mobile phone at predetermined time intervals. Therefore, the mobile phone charger prevents the propagation of microbes and germs adhered to the mobile phone, and prevents the surface of the mobile phone from being discolored.
