摘要： A plasma display apparatus comprises a waveform generator (WG) coupled between first and the second electrodes (SE1, CE1) to supply, across plasma cells (PCij), a sustain voltage (VCP) with slopes comprising a main part (MA) and a minor part (MI) succeeding the main part (MA). The main part has a duration longer than a formative time 5 lag (FTL) of the plasma cells (PCij), and the minor part has a smaller amplitude than the main part (MA). The plasma cells (pCij) are ignited and sustained by the minor part (MI). The main part (MA) has less steep slopes than the prior-art waveform. Consequently, the EMI produced by the main part (MA) will be at a lower frequency. The minor part (MI) has an amplitude which is relatively low and thus does not add considerably to the EMI, even 10 when its slopes are relatively steep. As the plasma is neither ignited nor sustained by the main part (MA), the main part (MA) further has a lower amplitude than the slope of the prior art and thus produces less EMI.

摘要： A method for driving pixels in a display device with an image signal is disclosed wherein the image signal comprises grey level information of an image to be rendered by the display device. The method comprises: dividing the image signal into sections, each section having a duration of a section period; dividing the section period into a plurality of adjacent, weighted sub-section periods; selecting for each of the pixels to be driven during the section period a sequence of adjacent sub-section periods in dependence on the grey level information, the selectable sequences lacking a common starting and ending point; driving the pixels during the sequences of adjacent sub-section periods. The method may be applied to displays driven by a pulse width modulated signal, such as sub-field as well as sub-line operated displays including plasma display panels, dynamic foil displays and passive displays.

摘要： The display apparatus displays a color image by controlling a number of emissions (NSP) in accordance with primary video signals (R, G, B). A calculating circuit (CC, CS) calculates a weighted sum (IL) of the primary video signals (R, G, B) and limits the number of emissions (NSP) dependent on the weighted sum (IL). In the weighted sum (IL), at least one of the primary video signals (R, G, B) is weighted differently than another one of the primary video signals (R, G, B). This allows selecting the contribution of the different primary colors (R, G, B) to the weighted sum (IL) such that the number of emissions (NSP) is controlled differently for different primary colors (R, G, B). Consequently, the power (P) can be limited for each of the primary colors (R, G, B) at substantially the same value.
摘要翻译：显示装置通过根据主视频信号（R，G，B）控制发射次数（NSP）来显示彩色图像。计算电路（CC，CS）计算主视频信号（R，G，B）的加权和（IL），并限制取决于加权和（IL）的发射次数（NSP）。在加权和（IL）中，主视频信号（R，G，B）中的至少一个与另一个主视频信号（R，G，B）的加权不同。这允许选择不同原色（R，G，B）对加权和（IL）的贡献，使得不同原色（R，G，B）的排放数量（NSP）被不同地控制。因此，基本上相同的值可以限制每种原色（R，G，B）的功率（P）。

摘要翻译：等离子体显示装置包括耦合在第一和第二电极（SE1，CE1）之间的波形发生器（WG），以便通过等离子体单元（PCij）提供具有斜率的维持电压（VCP）主要部分（MA）和次要部分（MI）在主要部分（MA）之后。主要部分的持续时间比浆细胞（PCij）的形成时间5延迟（FTL）长，并且次要部分具有比主要部分（MA）更小的幅度。血浆细胞（pCij）被小部分（MI）点燃并维持。主要部分（MA）具有比现有技术波形更陡峭的斜坡。因此，主要部分（MA）产生的EMI将处于较低的频率。次要部分（MI）的幅度相对较低，因此不会显着增加EMI，即使在斜率相对陡峭时也是如此。由于等离子体既不被主要部分（MA）点燃也不被维持，主要部分（MA）还具有比现有技术的斜率更低的幅度，因此产生更少的EMI。
