摘要： In an embodiment of the apparatus, a transparent inkjet head includes a first plurality of nozzles, and a color inkjet head includes a second plurality of nozzles. A color value measurement unit is configured to measure color values of ink applied to a plurality of pixels based on signals applied to the second plurality of nozzles of the color inkjet head and signals applied to the first plurality of nozzles of the transparent inkjet head. A control unit is configured to compare the measured color values of the ink applied to the plurality of pixels with a target value and to change the signals applied to the first plurality of nozzles of the transparent inkjet head such that the measured color values of the ink applied to the plurality of pixels are uniform.
摘要翻译：在该装置的实施例中，透明喷墨头包括第一多个喷嘴，彩色喷墨头包括第二多个喷嘴。颜色值测量单元被配置为基于施加到彩色喷墨头的第二多个喷嘴的信号和施加到透明喷墨头的第一多个喷嘴的信号来测量施加到多个像素的油墨的颜色值。控制单元被配置为将施加到多个像素的油墨的测量颜色值与目标值进行比较，并且改变施加到透明喷墨头的第一多个喷嘴的信号，使得测量的墨水的颜色值应用于多个像素是均匀的。

摘要： Example embodiments are directed to an ink discharge device that discharges uniform amounts of ink droplets from an inkjet head, and a control method thereof. Voltages applied to plural nozzles of the ink-head are changed based on different characteristics of the respective nozzles to discharge uniform amounts of ink droplets from the nozzles. Voltage increments are calculated using a fixed target color value so as to set color value dispersion and voltage increments are calculated using different target color values according to the nozzles so as to satisfy color value differences between the neighboring pixels and thus time required for a DPN process is shortened, and excessive changes of the applied voltages are prevented and thus a preparatory period required to mass-produce an LCD panel is shortened and yield of the LCD panel is increased.
摘要翻译：示例性实施例涉及从喷墨头排出均匀量的墨滴的排墨装置及其控制方法。基于各喷嘴的不同特性来改变施加到墨头的多个喷嘴的电压，以从喷嘴排出均匀的墨滴量。使用固定的目标色彩值计算电压增量，以便设定颜色色散，并根据喷嘴使用不同的目标色彩值来计算电压增量，以便满足相邻像素之间的颜色值差异，从而满足DPN处理所需的时间并且防止施加电压的过度变化，因此大量生产LCD面板所需的准备时间缩短，并且LCD面板的产量增加。

摘要： According to an example embodiment, an inkjet head cleaning apparatus that removes ink residue from an inkjet head after a purging operation in a non-contact manner includes a cleaning blade and a drive unit. The cleaning blade is at a distance from a bottom of the inkjet head. The drive unit is configured to move the cleaning blade in a direction parallel to the inkjet head bottom. The cleaning blade includes a flat upper surface parallel to the inkjet head bottom, and an ink film is produced between the flat upper surface of the cleaning blade and the inkjet head bottom. The cleaning blade also includes an elongated groove longitudinally in the upper surface of the cleaning blade.
