    摘要: A method of programming a driving waveform for an electrophoretic display (EPD) is provided, wherein the driving waveform includes several single pulses selected from K candidate pulse widths W1˜WK. First, K different constant pulse sequences corresponding to W1˜WK may be applied to the EPD, to obtain K sets of discrete electro-optical response data. A polynomial curve fitting algorithm is applied to obtain K relation curves C1˜CK between contrast ratios of the EPD to time, corresponding to the K sets of discrete electro-optical response data. After calculating the slope values S1˜SK of the curves C1˜CK at a current contrast ratio of the EPD, a maximum slope Smax among S1˜SK and a specific pulse width WS corresponding thereto are determined. A next contrast ratio of the EPD is calculated according to WS and Smax. The design process is repeated until the next contrast ratio of the EPD exceeds a target value.

    摘要: An electrophoretic display device is provided. The display device includes a first substrate, a second substrate opposite to the first substrate, a plurality of particles disposed between the two substrates, a driving circuit and a sensor. The driving circuit is configured for a display mode by imagewise driving the particles to display one or more images and configured for an idle mode by causing the particles to move away from at least one of the two substrates and to be non-imagewise dispersed in between the two substrates so as to form a substantially non-imagewise bistable state between the two substrates in the idle mode. The sensor senses or detects the usage status of the display device or the environmental parameters associated with a surrounding environment. The driving circuit is configured for either the display mode or the idle mode in accordance with the usage status or the environmental parameters.

    摘要: A method for compensating images, applied to an e-paper display where pixels are arranged as a pixel array displaying N-level grayscale images. Standard images from a first standard image to an N-th standard image which respectively correspond to a first-level grayscale value to the N-th-level grayscale value are provided. The e-paper display respectively displays the standard images. Actual grayscale values of each pixel of the e-paper display, from a first actual grayscale value corresponding to the first standard image to the N-th actual grayscale value corresponding to the N-th standard image, are obtained. Each m-th actual grayscale value is compared with an m-th-level grayscale value to generate an m-th compensating matrix, wherein m is a positive integer from 1 to N. Therefore, compensating matrices from a first compensating matrix to an N-th compensating matrix are generated and used to compensate an input image of the e-paper display.

    摘要: A halftone image generation method used in a system including a quantizer, a subtracter, a post-dithering module and an adder for generating a halftone image is disclosed. First, an original image including original pixels having original pixel values is received by the quantizer and a quantized image including quantized pixels having quantized pixel values according to a predetermined threshold is generated by the quantizer. The quantized pixel values from the original pixel values are subtracted by the subtracter so as to generate quantization error values. A post-dithering process is performed by the post-dithering module to generate dither values by using the quantization error values. The quantized pixel values of the quantized image are added to the dither values by the adder. Finally, the halftone image including halftone pixels having halftone pixel values is generated.
