摘要： The present invention provides an optical micromirror device and their array device and method for making the same. By introducing a sub coating layer and an over coating layer with a high reflective metal layer, the reflective layer of the micromirrors is protected from environmental circumstances, oxidation, degradation, acid, base, and galvanic corrosion of the micro-mechanical structures. Also the new coating structure enhances the performance of the micromirror array device by reducing degradation of the reflectivity of the metal layer, by providing anti-reflection in the optically non-effective area, and by protecting the micro-mechanical structures.

摘要： An organic light-emitting diode display driver adjusts the display scan period of the current driving the organic light-emitting diodes of a selected row based upon the sum of the display data corresponding to the selected row, thereby removing crosstalk in the OLED display panel. The driver includes an adder for adding the display data corresponding to the selected row and a scan period look-up table storing display scan period values. The scan period look-up table is configured such that it outputs display scan period values substantially proportional or inversely proportional to the sum of the display data to remove bright crosstalk or dark crosstalk, respectively, in the OLED display panel.

摘要： Provided is a method of using a complex salt as anti-spotting detergents, the complex salt being formed by the reaction of a photo-bleaching component having a water-soluble anionic substituent and a cationic surfactant. The complex salt is water insoluble in a stationary state, such as hand washing or pre-soaking for machine washing, so it effectively suppress the spotting of the photo-bleaching component into the interwoven webs of fabric. In addition, the complex salt can uniformly and rapidly dissolve in an agitating state, such as when machine washing, to allow the photo-bleaching component to absorb into fabric for effective bleaching and enhanced detergency.
