[0056] Figure 9 A schematic configuration of a droplet ejection device according to a second embodiment of the present invention is shown. This droplet ejection device uses ink as droplets. Such as Figure 9 As shown, the droplet ejection device 800 has a base portion 810 . On the base portion 810, a Y-axis stage 820 on which a liquid droplet ejection object is mounted, for example, a color filter for a display device is placed. The Y-axis table 820 can be Figure 9 Movement in the Y-axis direction. In addition, above the Y-axis table 820, the installation can be along the Figure 9 The X-axis table 830 moves in the X-axis direction. On the X-axis table 830, the inkjet type head 150 shown in the above-mentioned first embodiment of the droplet ejection section is mounted. In addition, the driving device (not shown) shown in the above-mentioned first embodiment connected to the shower head 150 by the FFC is also provided. The inkjet head 150 can move along the X-axis di...

Abstract

An ink jet type head control circuit is provided to reduce an influence of noise and to lower power consumption which includes a latch circuit (111) which respectively stores a first data block and a second data block following the first data block, for ink liquid drop discharge, and a data determination unit (112) which calculates a state transition data block based on the stored first and second data blocks. If the first data block is the same as the second data block, the data determination unit (112 outputs a state transition data block having a first value (Low), and if the first data block is different from the second data block, the data determination unit outputs a state transition data block having a second value (High). The invention also provides an ink jet type head module, a data transmitting method and a droplet discharging apparatus.

Description
