Disclosed herein is an epoxy resin composition including a core-shell structure of microemulsion silica surrounded by surfactant. By using the epoxy resin, surface roughness of a printed circuit board can be formed in an ecofriendly and economic manner. Further, high-reliability microcircuits can be realized by enhancing interface adhesive strength between a resin substrate and a metal layer in a buildup type printed circuit board.

Disclosed herein is a method of manufacturing a build-up printed circuit board (PCB), the method including: providing a first resin substrate; forming a roughness by coating an epoxy emulsion solution on a surface of the first resin substrate; and providing a core layer by forming a core circuit layer on the first resin substrate on which the roughness is formed. According to the present invention, roughness of a substrate can be formed in an environment-friendly and economical way by introducing a process of coating epoxy emulsion on a resin substrate. Further, a highly reliable fine circuit can be implemented by enhancing an adhesive bond between a build-up board material and a metal circuit layer.

An electric generating system using a solar cell improves the quality of output power by including a converter for converting an output voltage generated from the solar cell into DC voltage in a pulse shape. An inverter converts the DC voltage in the pulse shape into an AC voltage and applies the AC voltage to a power system and a control device for determining whether an erroneous operation of the electric generating system using the solar cell is generated or not based on an output voltage of the solar cell, an output current of the solar cell and a voltage of the power system. At least one inverter switching device among a plurality of inverter switching devices performs a switching at a frequency higher than a frequency during a normal operation at an interval where the erroneous operation is generated.

A method of controlling a touch panel display device, and which includes displaying a first display screen on the display device; receiving, via a controller of the touch panel display device and a touching signal indicating a touching action at a specific point on the first display screen; magnifying, via the controller, a predetermined area surrounding the specific point on the first display screen; displaying a second display screen including the magnified predetermined area with the specific point located at a center of the magnified predetermined area; receiving, via the controller, a selection signal indicating a selection of release touch icon displayed on the display device; and displaying the first display screen in response to the received selection signal.
摘要:
A method of controlling a touch panel display device, and a touch panel display device using the same, facilitate a user selection (touching) of a specific icon to improve the reliability of registering a touch event for the specific icon, thereby enabling smaller icons to be used with greater accuracy. The touch panel display device includes a touch panel exhibiting a plurality of coordinates corresponding to a screen area of the touch panel display device, the screen area including a zoom icon area; a touch panel controller for recognizing coordinates of a touch event, for storing the recognized coordinates in an internally provided memory, and for outputting a coordinates signal corresponding to the touch event by converting a value generated by the touch event into a corresponding coordinates value; a microprocessor for determining whether the coordinates value output from the touch panel controller corresponds to the zoom icon area of the screen area; a touch driver for outputting a zoom function signal corresponding to the coordinates value output from the touch panel controller; and a display for displaying a magnified icon area corresponding to the zoom icon area, if the microprocessor determines that the coordinates value output from the touch panel controller corresponds to the zoom icon area of the screen area. A method of controlling the above touch panel display device includes steps of displaying a zoom icon area on at least part of a screen made up of a plurality of coordinates; recognizing coordinates of a touch event, to determine whether the touch event corresponds to the displayed zoom icon area; and displaying, if it is determined that the touch event corresponds to the displayed zoom icon area, a magnified icon area corresponding to the zoom icon area.
