“…For many reflective display technologies, the appearance of the display depends on the exact luminance (position and distribution of the apparatus providing the illumination) and on the viewing angle of the user (receiving detector with optics) due to many of the issues we have already highlighted. 32,33 To provide a reasonable characterization, both specular and diffuse reflectance should be measured. 32,34 Appropriate ambient lighting conditions must also be considered, such as daylight readability and contrast, in a continued effort to define reflective-display standards.…”

Abstract— The commercial success of monochrome electronic paper (e‐Paper) is now propelling the development of next‐generation flexible, video, and color e‐Paper products. Unlike the early battles in the 1980s and 1990s between transmissive and emissive display technologies, there is a extraordinary diversity of technologies vying to become the next generation of e‐Paper. A critical review of all major e‐Paper technologies, including a technical breakdown of the performance limitations based on device physics and commentary on possible future breakthroughs, is presented. In addition, the visual requirements for color e‐Paper are provided and compared to standards used in conventional print. It is concluded that researchers have much work remaining in order to bridge the significant gap between reflective electronic displays and print‐on‐paper.

“…Angular dependant measurements have been carried out in the past and are still obtained in many situations with mechanical goniometric equipment [6], [7]. Those equipments are based on a mechanical scanning of the half space by moving the sample and/or the LMD (Light Measurement Device).…”

In this presentation, we will discuss recent advances and improvements in FPDs characterization methods. Several new and/or improved methods have been introduced in the past. After reviewing measurement requirements and basic principles of these methods, we will further focus on the characterization of reflective LCDs displays and introduce a new measurement methods allowing independent extraction of the characteristics of the display itself and the properties of the front surfaces.

“…Sometimes this task is solved by the development of both new electrooptic media such as ferroelectric or vertically aligned LC and new tiny TFTs (polysilicon or LCoS). [1][2][3][4] However, this process changes the display image quality rather slowly. Another way is to develop new driving circuitry with improved signal address algorithms.…”

Neuro‐filters used to enhance the image quality of video displays

Abstract— Digital images can be affected by external factors. There are many types of noise which affect digital images. Image filtration is a basic method used to suppress such hindrances. The disadvantage of most filtration methods and hardware filters created on their behalf is their inability to react to changes in the input signal. The structure of the filters used for image processing is similar to the structure of a bi‐dimensional neural‐network matrix. Investigations have shown that a system with serial‐parallel filters of any degree of complexity can be created on the basis of the neural‐network matrices. Each neural‐network matrix layer acts as a separate neuro‐filter which can be trained and adapted to changes in the characteristics of the images. The neural‐network matrices allow for the creation of various types of linear and nonlinear filters, as well as combinations on the basis of a uniform structure. It allows for the design of a universal hardware neuro‐filter structure that can perform as different types of filters by means of loading the connectors weight. In our paper, we consider the realization of neuro‐filters based on a neural‐network matrix, which allows the processing of both static and moving images and increases the image sharpness, suppresses the noise, and detects movable objects in the processed image.
