The cosmic microwave background (CMB) serves as a backlight to large-scale structure during the epoch of reionization, where Thomson scattering gives rise temperature anisotropies on small angular scales from kinetic Sunyaev Zel'dovich (kSZ) effect. In this paper, we demonstrate that technique kSZ tomography (velocity reconstruction), based cross correlations between CMB and 21cm surveys, can s...

Background: Preparing a formal transaction document is one of the specific duties of notaries public, which requires the use and observance of various substantive and formal conditions. Failure to comply with any of these conditions can lead to the annulment of the document by the court and the responsibility to compensate the clerks. Compensation by the clerks in various articles such as Artic...

We analyze how to realize Rec. 2020 wide color gamut with quantum dots. For photoluminescence, our simulation indicates that we are able to achieve over 97% of the Rec. 2020 standard with quantum dots by optimizing the emission spectra and redesigning the color filters. For electroluminescence, by optimizing the emission spectra of quantum dots is adequate to render over 97% of the Rec. 2020 st...

We propose a high dynamic range (HDR) liquid crystal display (LCD) with pixel-level local dimming. The device structure consists of a pixelated LCD dimming panel to control the backlight intensity entering the master LCD panel. According to our analysis and test cell experiment, this dual-panel display system possesses exceedingly high contrast ratio (> 1,000,000:1) and high bit-depth (> 14 bit...

Although there are different types of backlights (light sources) which are currently used for backlighting the latest Liquid Crystal Display modules, this paper will primarily focus on cold cathode fluorescent tubes (CCFT) which are currently the light source of choice in most LCD modules. The intent of the paper is to familiarize the reader with some potential problems and concerns associated ...
