backlight module

M. L. Huang, K. S. Chen, Y. H. Hung · 2002

Backlight application specializes in supplying light, with notable examples including liquid crystal display (LCD), hand-phone LCD, and PDA LCD. The integrated process capability and integrated process yield for cold cathode fluorescent lamp backlight are unknown. Process capability analysis is a highly effective means of assessing the process ability of backlight that meets specifications. A larger process capability index (PCI) implies a higher process yield, and lower expected process loss. Chen et al. [Int. J. Product. Res. 39 (2001) 4077], applied indices Cpu, Cpl, and Cpk to evaluate the integrated process capability for a multi-process product with smaller-the-better, larger-the-better, and nominal-the-best specifications, respectively. However, Cpk suffers from the weakness of being unable to reflect the specific process yield. This study selects index Cps to replace Cpk. Meanwhile, an integrated PCI for the entire backlight module is proposed, and the relationship between the PCI and process yield is described. A multi-process capability analysis chart, which reasonably accurately indicates the status of process capability for the backlight module, is designed for practical applications.

Backlight module

CHEN, PO-CHOU · Institutional Repository of Xi'an Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (Xian Institute of Optics and Precision Mechanics) · 2015

A backlight module includes a laser light source, a light guiding board located at a side of the laser light source, a first lens and a second lens both located at a light path of light beams emitted from the laser light source. The laser light source includes one laser diode or a plurality of laser diodes. The light guiding board includes a light incident face and a light emerging face. The first lens firstly converges and then diverges the light beams emitted from the laser light source. The second lens changes the light beams passed through the first lens to be parallel light beams. The parallel light beams have a larger width than that of the light beams just emitted from the laser light source. The parallel light beams enter the light guiding board via the light incident face of the light guiding board.

BACKLIGHT AND SHADOW

Gail Mason · 2010

Drawing on in-depth interviews with women reflecting a range of experiences of verbal hostility, physical violence and sexual violence, Spectacle of Violence explores the issues surrounding violence and hostility towards lesbians and gay men. Challenging current thinking, Gail Mason highlights the ways in which different identities, bodes and systems of through interact, and asks fundamental questions: * Where does violence come from?* What effects does it have?* How do lesbians and gay men manage the risk of violence?* What is the relationship between violence and power?She argues for the importance of thinking about homophobic violence in the context of other core issues such as gender and race. Focusing on 'real life' experiences of violence, The Spectacle of Violence is an important contribution to current thought about violence. Moving beyond issues of causation and prevention, it offers new ways of theorizing the relationship between identity, knowledge and power.

Backlight on the climber

Chen, Ying-Szu · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2022

The rise of rock climbing is a global phenomenon. Seven out of ten bouldering gyms opened during this decade in Stockholm. With the increasing sports climbing population, the lighting condition of sports facilities should be a concern, especially since electricity demand growth in buildings has been remarkably rapid. However, not much research has been conducted regarding investigating the effect of artificial lighting on indoor bouldering users' experiences. This thesis investigates a balance between addressing sustainable development goals number 7.3 and maintaining users' experiences while exercising, taking Klätterverket Gasverket as a case study. Different research methods have been used to provide a pilot study to be explored by others, including literature review, semi-structured interviews, and empirical study. This research has shown that it is hard to draw conclusions regarding the perceived qualities of light. The qualitative and quantitative results conclude that we can decrease electrical consumption in a situation that has sufficient daylight without sacrificing climbers’ experience. Adjusting the distance between the luminaire and climbing wall can slightly improve the average illuminance level and user experience.

An Optimized Backlight Local Dimming Algorithm for Edge-Lit LED Backlight LCDs

Seungwook Cha, Taehyeon Choi, Hoonjae Lee et al. · Journal of Display Technology · 2015

This paper presents an efficient optimized backlight local dimming method that minimizes power consumption under a given allowable distortion for liquid crystal displays with edge-lit light-emitting diode backlight. To reduce image quality fluctuation, an inequality constraint optimization problem is formulated using a given allowable distortion and the steepest descent method is used to solve the optimization problem. The experimental results show that the proposed method has better performance than previous methods at the same average power consumption in the unnoticeable level of the difference between the displayed images before and after dimming. Also, the proposed method reduces the risk of large performance degradation and reduces computation time by three times compared with the existing optimization based methods.

Ultracompact backlight-reversed concentration optics

Ming-Chin Chien, Yu Lung Tung, Chung-Hao Tien · Applied Optics · 2009

We demonstrate a concentration scheme based on a reversed tracing concept utilizing a conventional sidelit backlighting configuration. The optical arrangement consists of a groove sheet and a wedge plate without any coating or surface treatment. The proposed layout simultaneously exhibits two main features: coupling the collimated solar radiance into a wedge plate and guiding the flux to the exit plane of the wedge plate for use in direct daylight. The measurement revealed an optical efficiency of 52% in conjunction with an inverse aspect ratio of 9.51. In addition to the two-dimensional sidelit scheme, the proposed structure can also be rotationally convolved and extended to a three-dimensional solar concentrator with a high concentration ratio, which will certainly have an impact on solar energy and other optical functions because of its simplicity and versatility.
