20100248429 | METHOD FOR MANUFACTURING SEMICONDUCTOR MODULES - In a method for making a semiconductor module, a bump electrode and a recess are formed by etching a copper sheet. An insulating resin layer is formed, in the recess, up to a position lower than the height of the bump electrode, and then a semiconductor device and the copper sheet, including a wiring layer formed integrally with the bump electrode, are press-bonded together. The wiring layer is warped to protrude toward the semiconductor device, which assures the electrical connection between the bump electrodes and device electrodes. | 09-30-2010 |

20090058765 | Plasma Display Device - Between a sustain circuit outputting a sustain pulse and a scan circuit (even) driving a Y electrode of an even display line, there is provided a first switch capable of making the Y electrode of the even display line be in a high impedance state, and between the sustain circuit and a scan circuit (odd) driving a Y electrode of an odd display line, there is provided a second switch capable of making the Y electrode of the odd display line be in the high impedance state. By first and second switches, the Y electrode of the even display line and the Y electrode of the odd display line can be independently controlled to be in the high impedance states, whereby discharge of the even display line can be restrained in a sustain period of an odd frame, while a discharge of the odd display line can be restrained in a sustain period of an even frame, thereby realizing an interlace drive without complicating a circuit configuration. | 03-05-2009 |
20090135094 | Plasma Display Device and Method of Driving the Same - A plasma display device capable of realizing an interlace drive in one line display and an interlace drive in two lines display by switching thereof without deteriorating display quality, is provided. The interlace drive in one line display and the interlace drive in two lines display are realized such that: the interlace drive in one line display is performed by applying a sustain pulse for even display lines or odd display lines within a plasma display panel in each frame; and the interlace drive in two lines display is performed by applying the sustain pulse while setting the even display lines and the odd display lines adjacent above and below as one set and writing an identical data thereto. In addition, the all-cell reset is performed once per unit time at the interlace drive in two lines display, and an increase of background luminance is prevented by suppressing the increase in the number of times of the all-cell reset in the two lines display. | 05-28-2009 |
20090201226 | DRIVING METHOD FOR PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE - A driving method for a plasma display panel is disclosed in which sustain pulses are alternately applied to a pair of display electrodes of plural discharge cells provided in the plasma display panel to generate a sustain discharge, thereby causing an image to be displayed on the plasma display panel. The sustain pulses include a two-crests discharge voltage waveform having two maximum values in which discharges are generated twice in a half cycle. The driving method includes consecutively applying the two-crests discharge voltage waveforms to the pair of display electrodes; and making a time until the second one of the maximum values of the subsequently applied two-crests discharge voltage waveform is clamped longer than a time until the second one of the maximum values of the initially applied two-crests discharge voltage waveform is clamped. | 08-13-2009 |
20090201227 | PLASMA DISPLAY DEVICE - The plasma display device has a display panel having first and second display electrodes and address electrodes, an electrode drive circuit, and a drive control circuit for controlling the electrode drive circuit. The drive control circuit performs a reset drive control, address drive control and sustain drive control in each subfield. The drive control circuit performs an all cell reset drive control which resets all cells in a first subfield out of the plurality of subfields, and an ON cell reset drive control which resets ON cells in a second subfield.

20090201276 | DRIVING METHOD OF A PLASMA DISPLAY DEVICE AND A PLASMA DISPLAY DEVICE - At an on-cell reset, a positive ramp wave of an ultimate voltage, which is larger than a maximum voltage of a sustain pulse, and smaller than an ultimate voltage of a positive ramp wave applied to a Y electrode at an all-cell reset, is applied to the Y electrode to make a weak discharge occur at a cell where it is non-lighting at a previous sub-field and a wall charge thereof is decreased due to an influence from an adjacent cell, thereby, it makes it possible to return a wall charge state to a normal state, to be capable of lighting a cell to be lighted securely based on a display data. | 08-13-2009 |
