Abstract: A glass fiber and method for producing the same are provided. The method for producing the glass fiber includes a covering process, a mixing process, and a drawing process. The covering process is implemented by covering a plurality of silicon nitride powders onto a plurality of surfaces of a plurality of inorganic particles to form a plurality of modified inorganic particles. Based on a total weight of each of the modified inorganic particles being 100 wt %, a content of the silicon nitride powders is between 0.01 wt % and 5 wt %, and a content of the inorganic particles is between 95 wt % and 99.99 wt %. The mixing process is implemented by mixing the modified inorganic particles into a glass raw material. The drawing process is implemented by drawing the glass raw material having the modified inorganic particles mixed therein to form a glass fiber.

Abstract: A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods include (a) applying a first drive scheme to a non-zero minor proportion of the pixels of the display and a second drive scheme to the remaining pixels, the pixels using the first drive scheme being changed at each transition; (b) using two different drive schemes on different groups of pixels so that pixels in differing groups undergoing the same transition will not experience the same waveform; (c) applying either a balanced pulse pair or a top-off pulse to a pixel undergoing a white-to-white transition and lying adjacent a pixel undergoing a visible transition; (d) driving extra pixels where the boundary between a driven and undriven area would otherwise fall along a straight line; and (e) driving a display with both DC balanced and DC imbalanced drive schemes, maintaining an impulse bank value for the DC imbalance and modifying transitions to reduce the impulse bank value.

Abstract: A method and system for applying addressing voltages to pixels of a display involves receiving input data. The input data includes an indication of an addressing voltage impulse to be applied to a pixel via an electrode. One or more voltage sources are selected, to provide the addressing voltage impulse. The one or more voltage sources each have a pre-selected voltage, The selected one or more voltage sources are electrically connected to an electrode to apply the addressing voltage impulse to the pixel. The invention also provides a method of driving an electro-optic display which uses an intermediate image of reduced bit depth, and a method of driving an electro-optic display which uses a limited number of differing drive voltages, with higher voltage pulses being used before lower voltage pulses.
