    摘要： The present invention is directed to a driving method for compensating the response speed change of an electrophoretic display due to temperature variation, photo-degradation or aging of the display device, without a complex structure (e.g., use of sensors). This is accomplished by combining two waveforms, one of which causes the grey level to become dimmer and the other waveform causes the grey level to become brighter, as the response speed degrades.

    摘要： The color display of the present invention involves a two particle system and is capable of displaying multiple colors with high quality black and white states. The color states are suitable for highlighting function. The color display does not require alignment between the electrodes and the display cells in which a display fluid is filled, which significantly reduces the complexity of the design and also lowers the manufacturing costs.

    摘要： A method and mechanism for ensuring quality control in printed biological assays is provided. A multi-ejector system having a plurality of individual drop ejectors is loaded with a variety of biofluids. Biofluids include at least a carrier fluid, a biological material to be used in the testing, and markers, such as fluorescent dyes. Data regarding the biofluid loaded in each of the drop ejectors is stored along with an expected signature output of the biofluid. Particularly, the signature output represents signals from individual ones of the fluorescent markers included within the biofluid. Once a biological assay consisting of the biofluid drops has been printed, a scanner capable of detecting the markers scans the biological assay and obtains signature output signals for each of the drops of the biological assay. A comparing operation is undertaken to compare the obtained signature output through the scanning operation, with the expected signature output signals for the biofluid loaded in the corresponding drop ejector. The biological material itself may also be tagged with a marker to ensure its inclusion in the biofluid. By the comparing operation, it is possible to verify the biofluids were loaded in the proper drop ejector, including the proper biological material, and that the drop ejectors are functioning properly.
