Abstract: A method creates printing data applied to a printer that is capable of generating different sizes of ink drops. Firstly, a halftoning threshold table is created based on all possible combinations that are determined based on the quantity of the printheads and the sizes of ink drops quantity provided by each printhead. When the image data to be printed is received, each pixel of an image will correspond to one combination based on the halftoning threshold table. The corresponding combination is deemed as a halftoning encoded data and represented by several bits. These bits can be separated into plural groups, where the bits contained in each group are for driving a specific printhead. That is to say, each printhead has its own driving data so that the printing process will have superior efficiency.

Abstract: An overdrive device for driving a display panel includes a comparison circuit, a multiplexer, and an overdrive module. The comparison circuit receives pixel values of display cells of the display panel in a previous frame carried on a first decompressed data signal and in a current frame carried on a second decompressed data signal, and determines whether the brightness/color of each target display cell is static to assert or de-assert a selection signal. The multiplexer outputs an output signal to output at least a reference pixel value for the overdrive module according to the selection signal. The overdrive module receives the reference pixel value, and overdrives the target display cell according to an overdrive value corresponding to a combination of the received current and reference pixel values stored in a look-up table of the overdrive module.

The overdrive computation apparatus is used for generating a desired overdrive gray-level value and includes first and second addition/subtraction devices, a priority encoder, and a computation device. The first addition/subtraction device outputs a difference value indicating difference between a first overdrive gray-level value OD1 and a second overdrive gray-level value OD2. The priority encoder determines a decision signal according to the difference value. The computation device receives first gray-level data, determines a first computation according to the decision signal, and performs the first computation on the first gray-level data to output operated gray-level data. The first gray-level data indicates a value lying between the ith first gray-level index value X(i) and the (i+1)th first gray-level index value X(i+1).

Abstract: A cross color suppressing apparatus used for suppressing the cross color of a frame is provided. The frame has several pixels, and the image data of each pixel include a luminance and a chrominance. The apparatus includes a diagonal edge detector, a cross color detector and a chrominance suppressing unit. The diagonal edge detector is used for determining whether target pixel is on a diagonal edge according to the luminance of the target pixel and that of its neighboring pixels. The cross color detector is used for determining whether the chrominance of the target pixel is substantially different from that of its neighboring pixels. If both the determination results of the diagonal edge detector and the cross color detector are true, the chrominance suppressing unit suppresses the chrominance of the target pixel and its neighboring pixels.

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 cleaning device is mounted on either of the sides of an ink-jet printer. The cleaning device uses the power source of a paper delivering motor to transmit power to the cleaning units so that the cleaning units rotate to perform cleaning and scrubbing operations for an ink-jet print head. When the printer performs printing operations, the paper delivering motor is used to deliver paper without causing an interference with the ink-jet print head during the printing operation. When the ink-jet print head needs to be cleaned, an ink carriage moves to be opposed to the cleaning device under the ink carriage, then, the paper delivering motor supplies power to drive an external transmission device set. The external transmission device set drives the cleaning device on the revolving seat to rotate so as to clean the ink-jet print head of the ink carriage.

Abstract: A method of forming micro holes metal membrane by inkjet printing spray micro droplets of a catalyst in the holes after the substrate surface is treated. The catalyst adsorbs and dries on the inner walls of the holes. After that, the surface properties of the substrate are changed so that the coating solution readily enters the holes and forms a membrane on their inner walls. This can avoid incomplete metal coating due to residual air in the holes and forming a disconnected circuit. Moreover, the adhesive force between the inner wall of the holes and the metal improves the situation of coated layer peeling. The method reduces the use of precious catalyst, the fabrication procedure, and the production of photo resist etching waste. Since it does not require expensive equipment and space for exposure, developing, laser drilling, the method lowers the production cost and satisfies the environmental protection requirements.
