A liquid crystal driving device of the present invention is provided with a display data memory of a capacity that can be divided into two parts, and a switch circuit that is used to switch an addressing method of the display data memory between multi-tone display in a dual-scan and simple-tone display in a single-scan, so as to enable a driving IC to be shared between liquid crystal display devices that are used to display high-quality and multi-tone images and liquid crystal display devices that require less tone. Such a liquid crystal driving device can be used to reduce production cost of various types of liquid crystal display devices.

An apparatus and method for operating a plasma display panel (PDP) capable of removing or preventing peaking noise or voltage spike is disclosed. After substantial video data is completely recorded in the address electrode and/or after the last scan pulse or signal on the last scan electrode, the apparatus floats the address electrode or maintains the address electrode at a predetermined voltage, such that it prevents peaking noise from being received from the scan electrode and the sustain electrode, resulting in no erroneous discharge. As a result, the apparatus improves an image quality of the PDP, and increases operation efficiency of the PDP including use of single scan rather than dual scan.

A self light emission display device which substantially enables dual scan drive by one data driver comprises a plurality of scan lines K1, K2, . . . which are arranged in a horizontal direction, a plurality of data lines A1, A2, . . . which intersect these scan lines and are arranged in a vertical direction, and a plurality of light emitting elements Ra11, Rb11, . . . arranged on intersecting areas of the scan lines and the data lines. Cathode terminals of the light emitting elements whose anode terminals are connected respectively to the two adjacent data lines A1, A2 are connected to different scan lines one by one. Any two of the scan lines are selected for scanning simultaneously. Thus, since light emission duty of each EL element can also be approximately doubled, instantaneous light emission intensity of each EL element can be set low, and stress on the EL elements can be reduced. Further, since respective data lines can be drawn from one side end portion of the display panel, dual scan drive becomes substantially possible by one data driver.

A luminescent display device is disclosed. The luminescent display device is comprised of an array of pixels, a first driving chip and a second driving chip. The array of pixels is comprised of columns and rows of pixels. The first driving chip is connected a first pixel of the array of pixels, and the second driving chip is connected to a second pixel of the array of pixels. The second pixel is adjacent to the first pixel. The first driving chip is not connected to all pixels in a row of the at least one row of pixels.

The present invention relates to a plasma display panel with barrier ribs configured in a closed shape. The panel has sub-pixel cells each with a cell area that is defined by the closed shape barrier ribs, sustain electrodes each spaced apart in a row direction at a predetermined cell length, and data electrodes each overlapping a barrier rib wall in a column direction and extending under the cell area. A plurality of the sub-pixels cells in a delta configuration defines a color pixel, whereby a dual scan gap of a predetermined gap length is formed between a pair of the data electrodes in the column direction, and a gap is formed between the row barrier ribs and data electrodes.

The invention provides a method for the high-precision measurement of coordinates of at least one structure on a substrate. A stage traversable in X/Y coordinate directions is provided, which is placed in an interferometric-optical measuring system. The structure on the substrate is imaged on at least one detector (34) via a measuring objective (21) having its optical axis (20) aligned in the Z coordinate direction. The structure is imaged with the so-called Dual Scan. Systematic errors can thereby be eliminated.

The present invention describes a deposition system. The deposition system includes a deposition source that generates a deposition flux containing neutral atoms and molecules. A shield defining an aperture is located in the path of the deposition flow. The shield passes the deposition flux through the aperture and virtually blocks the deposition flux from propagating anywhere else behind the shield. There is an underlying support near the shield. A dual scanning system utilizes first and second motions to scan the underlying support associated with the well.

A single-chip column driver for organic light emitting diode (OLED) display is disclosed. Instead of using two column drivers for dual scan, the present invention uses one column driver driving both the upper and the lower OLED panels. The column driver has a two set of output circuitry: one for driving the upper panel and the other for driving the lower panel. The single chip solution of the present invention eliminates the problem of display uniformity without increasing the part count. The invention also enables independent control of RGB without further increasing the part count.

The screen of a liquid crystal panel is divided into two portions. In the divided screens (upper screen and lower screen), the corresponding common electrodes (each for one divided screen) are simultaneously driven. The driving signal (common signal C1) of the upper screen and the driving signal (common signal C2) of the lower screen change in one cycle of four frame periods. More specifically, in the above-mentioned cycle, the common signal C1 changes in a pattern (1->1->1->-1), and the common signal C2 changes in a pattern (1->-1->1->1) in synchronization with each other. Accordingly, upon comparison of the common signals C1 and C2, it appears that the signal having the same waveform is applied to the common electrodes while being out of phase with each other. Thus, a difference of the drive frequency between the upper screen and the lower screen is eliminated. It is thus possible to provide an inexpensive liquid crystal apparatus, which is connected to an existing dual-scan interface, without degrading the display quality.
