Abstract: Display data read out from a picture display memory region within a UMA memory is written in a FIFO, and display data is transferred from the FIFO at a timing required by a liquid crystal panel, wherein a timing of reading out display data from the UMA region and a timing of transferring display data to the liquid crystal panel are made asynchronous to each other. Also, upon detection of writing in a display data region, display data for one picture frame is transferred to the liquid crystal panel, whereby the reduction in the bandwidth for CPU's memory accesses to the UMA is prevented, and the reduction in the overall power consumption of the display system is realized.

Abstract: An acceptable duration is defined as the time necessary for allowing the diameter of a microdroplet that has reached the substrate to become a maximum acceptable droplet diameter. A scanning speed is set in such a manner that the microdroplet that has been received by the substrate reaches a radiating position from a droplet receiving position immediately after the acceptable duration has passed since reception of the microdroplet by the substrate. A laser beam is radiated onto the microdroplet immediately after the acceptable duration has passed since the reception of the microdroplet Fb by the substrate, or when the microdroplet is located at the radiating position.

Abstract: A drive waveform-determining device is configured and arranged to determine an exact drive waveform for a droplet discharge device with minimal trials. The drive waveform-determining device uses an analysis unit that stores optimal weight and velocity for droplets, and basic configurations of drive waveforms. A weight- and viscosity-determining unit measures the weight of droplets discharged from a discharge head. The analysis unit measures the velocity of the droplets with the aid of a CCD camera and a strobe light. The analysis unit reads a basic configuration of a drive waveform and adjusts the drive waveform so that the measured weight and velocity match the weight and velocity stored in the analysis unit. The analysis unit then stores the adjusted drive waveform.
