Abstract: A color backlight device and fabrication method thereof is provided. A surface conduction emitter display with more than one color serves as the color backlight device. The color backlight device can be used in a liquid crystal display (LCD) to obviate the use of a color filter. The invention also provides a color display control method of the LCD and a pixel arrangement method of the color backlight device.

Abstract: A piezoelectric fluid injection device and a driving voltage calibration method thereof. The piezoelectric fluid injection device includes at least one inkjet printhead comprising a plurality of nozzles, at least one voltage control element connecting to the inkjet printhead, a controller connecting to the voltage control element, a reference capacitor connecting to an auxiliary voltage control element and the controller in parallel with the inkjet printhead.

Abstract: A pattern printing system and data processing method thereof are disclosed, which are suitable for printing patterns on printed circuit boards or data format rearrangement printing used in displays. The pattern printing method includes a process for interpreting scription data into matrix data, a procedure for modulating the print head resolution and the printing resolution, a procedure for interpreting and transmitting data commands, a procedure for rearranging memory data, and a procedure for firing data synchronously so as to achieve high-resolution printing and to continuously modulate any print data.

Abstract: A temperature control apparatus for a printhead, disposed on a printer and controlled by a printhead driver. A printhead temperature detector detects and outputs a printhead temperature. A controller receives the temperature and searches a corresponding temperature-voltage table selected in accordance with a printhead mode signal to acquire a voltage value. A voltage regulator coupled to power and the controller outputs the corresponding voltage according to the voltage value to the printhead to adjust the temperature of the printhead.

Abstract: A method and a device are used to generate print data of any resolutions based on ink volume from the original print data. The print data in the form of halftoned levels are first transferred to the ink image according to the relation between halftone level and drop number obtained by the experiment of ink control. Then, the ink image of original resolution is converted to the ink image of desired resolution by the concept of conservation ink volume per pixel where the amount of ink drops in the unit area stays coherent in the conversion. Finally, each drop number of the converted ink image is transferred to the corresponding halftone level to generate the printing data that can be accepted by the printing device.

Abstract: A print alignment method comprises detecting a skew direction of the printhead, receiving column data, corresponding to columns of printhead nozzles, dividing column data into N sections, selecting individual N column data, when the skew is to the right, the printhead receives the first section of first column data, the second section of second column data, the third section of third column data and so on; and when the skew direction is to the left, the printhead receives the Nth section of the first column data, the (N-1)th section of the second column data, the (N-2)th section of the third column data, and so on.
