LASER LIGHT SOURCE DEVICE AND DISPLAY APPARATUS |
| 摘要 |
A laser light source device includes a semiconductor laser, a current supplying unit to supply a driving current to the semiconductor laser, and a signal generator to generate current intensity data for setting an intensity of the driving current. The signal generator generates, for an input signal corresponding to continuous pixels for a same color, a plurality of sets of the current intensity data indicating current intensities different from each other, and transmits the plurality of sets of the current intensity data to the current supplying unit while sequentially switching the plurality of sets of the current intensity data. The current supplying unit drives the semiconductor laser based on the plurality of different sets of the current intensity data. |
