DISCHARGE LAMP LIGHTING DEVICE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To digitize the peak current control flowing in the discharge tube while securing sufficient precision. <P>SOLUTION: In the image screen equipment using a cold cathode-ray tube as a light source, control of the current flowing in the discharge tube is carried out by PWM in the digital circuit and the resolution of the PWM is expanded in the bit reduction circuit. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
