The scanning liquid crystal (LC) prism type 3D displays may solve the resolution degradation problem but introduce another issue, dynamic crosstalk. To improve the 3D perception, a novel impulsive driving backlight method with multi-electrode driving structure scanning LC prism is proposed. With this method, the dynamic crosstalk can be reduced by 35.2%.

FAN7340 is a single-channel boost controller that integrates an N-channel dimming MOSFET using Fairchild’s proprietary planar DMOS technology. The IC operates as a constant-current source for driving high-current LEDs. FAN7340 uses a current-mode control with programmable slope compensation to prevent sub-harmonic oscillation and provides protections such as Open-LED Protection (OLP) and Over-V...

PURPOSE Accurate characterization of diagnosis instruments is crucial in medical applications such as radiology and clinical neurosciences. While classical CRT medical displays have been replaced almost exclusively with liquid crystal devices (LCDs), the assessment of their temporal properties (response times) is still largely based on heuristic methods, which have not been evaluated thoroughly...

High dynamic range (HDR) displays with dual-panels are one type of that can provide HDR content. These composed a white backlight panel and colour LCD panel. Local dimming algorithms used to control the in order reproduce content high contrast at fidelity. However, existing local usually process low (LDR) images, which not suitable for processing images. In addition, these methods use hand-craf...

second. The other ciliates studied obviously have a much lower speed of coordinating impulse. These values are so far below the velocities of true neural impulses that it is not possible to consider a "neuromotor" factor in the coordination of these Protozoa. Further investigations are in progress along the lines indicated here and will be reported in detail. The writer is indebted to Dr. W. M....

A micro-projection dynamic backlight for multi-view three-dimensional (3D) display is proposed. The proposed includes a light emitting diodes (LEDs) array, lenticular lens and scattering film. LED the lens, film construct structure. In this structure, LEDs in array are divided into several groups. from each group can be projected to by forms series of bright stripes. different groups have horiz...

Color gamut and static and dynamic color shifts of a multi-domain in-plane-switching liquid crystal display (IPS LCD) are calculated quantitatively using RGB (red, green, and blue) light-emitting diodes (LEDs) and cold-cathode fluorescent lamp (CCFL) backlights. Simulation results indicate that the LED backlight exhibits a wider color gamut, better angular color uniformity, and 2-4X smaller sta...
