Optimal dimension of edge-lit light guide plate based on light conduction analysis.

Dimensions of the edge-lit light guide plate (LGP) have a non-negligible impact on its output performance based on a pre-determined micro-dot array. However, how the LGP's dimension affects the performance has not been systematically researched. In this paper, the dimension of the LGP is numerically established as a function to the light output performance, which can be divided into four successive procedures.

Edge/direct-lit hybrid mini-LED backlight with U-grooved light guiding plates for local dimming.

Current mini-LED backlights improve high-dynamic-range liquid crystal displays (LCDs) by using tens of thousands of direct-lit sources for local dimming. However, relative thick profile and high power consumption are the inherent limitations while compared with edge-lit backlights. By synthesizing edge- and direct-lit advantages, we propose a novel hybrid mini-LED backlight equipped with a specially designed integrated light guiding plate (LGP) for large-area displays.

Numerical Analysis of Droplets from Multinozzle Inkjet Printing.

Multinozzle printing processing with the fabrication of a functional material film lays the foundation for the development of efficient scale production of a photoelectric device. However, a prominent challenge is how to realize the volume uniformity of the droplets. Here, a classical analysis method is introduced first by printing poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) to analyze the behavior of droplets.

Analytic design of light extraction array for light guide plate based on extended sources.

Light extraction array, comprised of millions of discrete scattering dots randomly distributed on edge-lit light guide plates (LGPs), determines both the light efficiency and spatial uniformity of liquid crystal displays. However, it is hard to define by a specific mathematical expression. Here, we propose a novel analytic design for light extraction array based on geometrical optical principles.
