摘要： PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus outputting an accurate drive signal while ensuring the follow-up property of the drive signal to a drive waveform signal.
SOLUTION: The drive waveform signal serving as a reference for driving a liquid jetting nozzle actuator is generated in a drive waveform signal generating circuit 25, and the drive waveform signal is pulse-modulated in a modulating circuit 26. The modulated signal is power-amplified by a pair of push-pull coupled switching elements of a digital power amplifier 28, and the power-amplified modulated signal is smoothed by a smoothing filter 29 and output toward the nozzle actuator. At this time, a modulation period of pulse modulation is changed based on data of the drive waveform signal. Specifically, the follow-up property to the drive waveform signal is ensured by shortening the modulation period when the electric potential of the drive waveform signal changes, to avoid such a short pulse that the switching elements cannot respond.

摘要： PROBLEM TO BE SOLVED: To provide an electro-optical device having a high display capability by using a photoconductive unit wherein light use efficiency of a light source is improved.
SOLUTION: In a backlight unit, such as an edge light system, for use in the electro-optical device such as a liquid crystal display, a photoconductor and a holder supporting the photoconductor are integrated by an injection molding method such as a two-color (multi-color) molding method. The holder is made of a resin material having a high reflectivity. Thus, incident light from a light source is not output through a gap between the photoconductor and the holder. In other words, the incident light is guided inside the photoconductor and effectively output to an electro-optical panel side. As a result, the electro-optical device having a high display capability is provided.
