PROJECTOR

摘要

A projector that outputs a first picture and a second picture alternately, wherein a control section performs first control and second control, controls a discharge lamp driving section. In the first control and the second control, the absolute value of a drive current is relatively small in a first period and relatively large in a second period. In the first control, the energy provided to a first electrode in the second period is greater than the energy provided to the second electrode in the second period. In the second control, the energy provided to the second electrode in the second period is greater than the energy provided to the first electrode in the second period.

主权项

1. A projector that outputs a first picture and a second picture alternately while performing switching between the first picture and the second picture with given switching timing, comprising:
a discharge lamp including a first electrode and a second electrode; a discharge lamp driving section that supplies, to the discharge lamp, a drive current that drives the discharge lamp; and a control section that controls the discharge lamp driving section, wherein
a switching period sandwiched between a time at which switching is performed and the next time at which switching is performed starts with a first period and ends with a second period,the control section performs a first control processing in a first control period which continues at least for one switching period and performs a second control processing in a second control period which continues at least for one switching period,in the first control processing and the second control processing, the control section controls the discharge lamp driving section so that the absolute value of the drive current becomes relatively small in the first period and becomes relatively large in the second period,in the first control processing, in the second period, the control section controls the discharge lamp driving section so that the drive current by which the energy provided to the first electrode becomes greater than the energy provided to the second electrode is supplied to the discharge lamp, andin the second control processing, in the second period, the control section controls the discharge lamp driving section so that the drive current by which the energy provided to the second electrode becomes greater than the energy provided to the first electrode is supplied to the discharge lamp.
