[0034] Digitally encoded image and color model overview

[0035] figure 1 A typical digital image is shown. The encoded image includes a two-dimensional array of pixels 102 . exist figure 1 In , each small square, such as square 104, represents a pixel, which is generally defined as the smallest unit in an image specified by a numerical value in digital coding. Each pixel is a point, typically represented by a pair of values, corresponding to orthogonal x-axis 106 and y-axis 108, respectively. For example, pixel 104 has x,y coordinates (39,0), while pixel 112 has coordinates (0,0). In digital encoding, pixels are represented by numerical values ​​that describe how the area of ​​the picture corresponding to the pixel will appear on the screen, displayed on a computer monitor or other display. Usually, for a black and white image, each numerical value from 0-255 is used to represent the corresponding gray level that each pixel presents, with "0" representing black and "25...

Abstract

The invention discloses a system and method for processing standard video signal data and image data, selecting colors in a wide color gamut, and displaying color video and images on a bright reflective display panel. In some application examples, the incoming video / image signal is first converted from RGB encoding to encoding based on a new color system that encodes color using spectral, black and white components. Reflective display panels include an array of pixels, each pixel containing one or more self-parallel interferometric modulators ("SPIMs"). Each SPIM consists of multiple electrodes located on the bottom plate, a fixed top plate and a movable plate, where the top plate and the movable plate are separated by a cavity. Applying an appropriate voltage on the electrodes can adjust the cavity depth of the SPIM, making the SPIM reflect a specific wavelength of color or making the SPIM display black or white.

Description

[0001] Cross References to Related Patents [0002] This patent application claims the benefit of Provisional Patent 61 / 843,491 filed on July 8, 2013. technical field [0003] The present invention relates to reflective color displays, and more particularly to systems and methods for controlling interferometric dimmers in reflective displays for obtaining color images with high brightness and wide color gamut. Background technique [0004] Various display technologies have been developed by studying the properties of ink and paper, as well as transmissive liquid crystal displays ("LCD displays"), reflective liquid crystal displays, electroluminescent displays, organic light emitting diodes (OLEDs), electrophoretic displays and many others display technology. Reflective display is a recently developed display that is gaining more and more attention in the market and has been widely used in e-book readers. In contrast to conventional flat panel LCD displays, which require a ...
