    • A gradation voltage adjustment section for increasing a positive gradation voltage VHX of an X-th gradation and a negative gradation voltage of the X-th gradation so that the increment corresponds to a charge pull-in amount ΔV is provided in a gradation voltage generation circuit of each source driver. In at least one embodiment, a center value between the positive and negative gradation voltages is adjusted for each driver in accordance with a slant of the charge pull-in amount ΔV in a direction of a gate signal line, thereby suppressing a flicker without varying a gradation characteristic. Further, a center value between the positive and negative gradation voltages is adjusted for each horizontal line or for every plural lines in a single frame in accordance with a horizontal direction deviation and a vertical direction deviation of the charge pull-in amount ΔV in a transfer block, thereby suppressing a flicker without varying a gradation characteristic.
    • 灰度电压调节部分,用于增加第X灰度的正灰度电压VHX和第X灰度的负灰度电压,使得增量对应于电荷引入量ΔV被提供在灰度电压产生电路 的每个源驱动程序。 在至少一个实施例中,根据栅极信号线的方向上的电荷引入量ΔV的斜率,针对每个驱动器调整正和负灰度电压之间的中心值,从而抑制闪烁而不改变 灰度特征。 此外,根据转印中的电荷引入量DeltaV的水平方向偏差和垂直方向偏差,针对每个水平线或单个帧中的每一行调整正和负灰度电压之间的中心值 从而抑制闪烁而不改变灰度特性。

    • A high pressure discharge lamp includes a glass enclosure defining a hermetically sealed discharge space filled with an ionizable gas. A pair of electrodes extend into the discharge space, each electrode having a connection end and a discharge end, between which electrodes, in the operating condition of the lamp, a discharge takes place. A pair of holding portions on opposite sides of the glass enclosure and hold the respective connection ends of the electrodes. Metal lead foils connected to the connection ends are sealed in the holding portions. One or both of the connection ends is shaped, e.g., as a conical frustrum or as a wedge, such that the thickness of its inner end is reduced with respect to the thickness of its outward end. The joining portion of the glass enclosure is internally necked at a position adjacent the reduced thickness portion of the connection end.
    • 高压放电灯包括限定充满可离子化气体的密封放电空间的玻璃外壳。 一对电极延伸到放电空间中,每个电极具有连接端和放电端,在这些电极的工作状态下,电极发生放电。 在玻璃外壳的相对侧上的一对保持部分,并且保持电极的相应连接端。 连接到连接端的金属铅箔被密封在保持部分中。 一个或两个连接端被成形为例如圆锥形或楔形,使得其内端的厚度相对于其外端的厚度减小。 玻璃外壳的接合部分在与连接端部的厚度减小部分相邻的位置处被内颈缩。
