Abstract:
A method of driving an electrophoretic display is set forth for avoiding image-edge residual while sequentially displaying a first frame and a second frame. During the time of displaying the first frame, set a common voltage to be a first voltage, apply a second voltage different from the first voltage to a first pixel for writing a first data signal into the first pixel, and apply the first voltage to a second pixel adjacent to the first pixel for retaining a second data signal of the second pixel, which is different from the first data signal. During the time of displaying the second frame, set the common voltage to be the second voltage, apply the first voltage to the first pixel for writing the second data signal into the first pixel, and apply the first voltage to the second pixel for retaining the second data signal of the second pixel.
Abstract:
A method for producing a light reflecting structure in a transflective or reflective liquid crystal display uses one or two masks for masking a photoresist layer in a back-side exposing process. The pattern on the masks is designed to produce rod-like structures or crevices and holes on exposed and developed photoresist layer. After the exposed photoresist is developed, a heat treatment process or a UV curing process is used to soften the photoresist layer so that the reshaped surface is more or less contiguous but uneven. A reflective coating is then deposited on the uneven surface. One or more intermediate layers can be made between the masks, between the lower mask and the substrate, and between the upper masks and the photoresist layers. The masks and the intermediate layers can be made in conjunction with the fabrication of the liquid crystal display panel.
