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.

A pulse generating apparatus includes a base current supply section for generating a constant DC current having a first prescribed current level for turning on a xenon lamp, and a pulse current section for adding a pulse current having a second current level greater than the first current level and a prescribed pulse duration within a prescribed repetition period to the constant DC current. The base current supply section and pulse current section should satisfy the following equations:1.4.ltoreq.Imax/Imini.ltoreq.60.2.ltoreq.t/T.ltoreq.0.7T.ltoreq.1/40Where Imax is the sum of the first and the second prescribed current levels, Imini is the first prescribed current level, T is the prescribed repetition period, and t is the prescribed pulse duration.When the pulse current added to the DC current is supplied to a xenon lamp, the xenon lamp outputs a strong light during the pulse duration of the pulse current, and a feeble light during the absence of the pulse current.

摘要:
This invention provides a small metal halide lamp which has a power input of 100 W or less, provided with: an arc tube having a pair of electrodes spaced apart from each other and containing a rare gas, mercury, sodium halide and scandium halide therein; and an envelope for housing the arc tube. The mixing ratio of sodium halide to scandium halide based on weight is 3:1 to 10:1, and the total content of the sodium halide and the scandium halide is 10 to 40 mg per unit volume (cc) of the arc tube. At least one phospor selected from the group consisting of a manganese-activated magnesium fluorogermanate phosphor and a cerium-activated yttrium aluminate phosphor is applied to the inner surface of the envelope. In addition, a green-emitting phosphor is preferably coated on the inner surface of the envelope.
