摘要： Phosphor and a plasma display device are provided whose deterioration in brightness of phosphors and a degree of change in chromaticity are alleviated and whose discharge characteristics are improved and that has excellent initial characteristics. Phosphor of the present invention is an alkaline-earth metal aluminate phosphor containing an element M (where M denotes at least one type of element selected from the group consisting of Nb, Ta, W and B). In this phosphor, a concentration of M in the vicinity of a surface of the phosphor particles is higher than the average concentration of M in the phosphor particles as a whole. A plasma display device according to the present invention includes a plasma display panel (100) in which a plurality of discharge cells in one color or in a plurality of colors are arranged and phosphor layers (110B, 110R, 110G) are arranged so as to correspond to the discharge cells in colors and in which light is emitted by exciting the phosphor layers with ultraviolet rays. The phosphor layers include blue phosphor (110B), where the afore-mentioned phosphor is used as the blue phosphor (110B).

摘要： Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realised by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

摘要： When a gas discharge panel is driven, a voltage is applied between scan and address electrode groups to perform set-up. The voltage waveform has four intervals. In a first interval, the voltage is raised in a short time (less than 10 µs) to a first voltage, wherein 100 V ≤ first voltage
摘要翻译： 当气体放电板被驱动时，在扫描和地址电极组之间施加电压以执行设置。 电压波形有四个间隔。 在第一时间间隔内，电压在短时间内（小于10μs）升高到第一电压，其中100V≤第一电压<起始电压。 然后，在第二个时间间隔内，电压升高到不低于起始电压的第二个电压，绝对梯度小于第一个时间间隔内电压升高的绝对梯度（不超过9 V /μs）。 接下来，在第三时间间隔中，电压在短于第二电压的时间（不超过10μs）内降低至不超过启动电压的第三电压。 此后，在第四个时间间隔内，电压进一步降低（100μs至250μs），梯度小于第三个时间间隔内的电压下降。 整个电压波形占用的时间不应超过360μs。 这意味着可以适当地累积壁电荷，即使在寻址周期内施加的脉冲很短（不超过1.5μs），也可以执行稳定的寻址。 这延长了放电维持时间并提高了亮度。

摘要： A plasma display panel (PDP) driving method is disclosed for a PDP in which a plurality of discharge cells are arranged between a pair of substrates (11,12), the method repeating a number of steps to perform image display. One of the steps is a set-up step for applying a set-up pulse to each of the plurality of discharge cells to accumulate charge in each discharge cell. The set-up pulse is a staircase waveform which either rises or falls in at least two steps. For a rising waveform, the voltage jump for the first-step rise is no less than V f -70V but no greater than V f , where V f is a discharge voltage. For a falling waveform, the ratio of a first-step voltage fall (V 1 ) to a peak voltage (V st ) is no less than 0.05:1 and no more than 0.8:1 and the ratio of (a) a time (t p ) form the end of the first-step fall to the start of the second step-fall to (b) pulse width (t w ) being no less than 0.05:1 and no more than 0.6:1.
