1. 1. Soft proofing using liquid crystal displays

   Författare :Sara Leckner; KTH; []
   Nyckelord :displays; lcd; crt; premedia; prepress; soft proof; workflows;

   Sammanfattning : Development of colour management systems, the level ofstandardisation, as well as the embedding of facilities forcolour management into computer operating systems and software,enables successful future interoperability of colour reproductionin the graphic arts industry. Yet colour reproduction from onemedium to another, still gives rise to inconsistencies. LÄS MER

3. 2. Process Development for Extraction and Separation of In and Y from Discarded Flat Panel Displays

   Författare :Jiaxu Yang; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LCD; Indium; Recycling; Cyanex 923; Leaching; DEHPA; Solvent Extraction; Yttrium;

   Sammanfattning : From the time of their invention in the 1970s, flat panel displays (FPDs) have slowly become the most used type of displays in televisions, computers, and cell phones. A major subgroup of FPDs is lLiquid crystal displays (LCDs). LÄS MER

4. 3. Optical Characterization and Optimization of Display Components : Some Applications to Liquid-Crystal-Based and Electrochromics-Based Devices

   Författare :Iryna Valyukh; Claes-Göran Granqvist; Ewa Wäckelgård; Hans Arwin; Ola Hundery; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ellipsometry; liquid crystal; LCD; optical anizotropy; electrochromic; inverse problems; Optics; Optik; Optical physics; Optisk fysik; Numerical analysis; Numerisk analys; Solid State Physics; fasta tillståndets fysik; Information Systems; data- och systemvetenskap;

   Sammanfattning : This dissertation is focused on theoretical and experimental studies of optical properties of materials and multilayer structures composing liquid crystal displays (LCDs) and electrochromic (EC) devices. By applying spectroscopic ellipsometry, we have determined the optical constants of thin films of electrochromic tungsten oxide (WOx) and nickel oxide (NiOy), the films’ thickness and roughness.

5. 4. Investigations of Optical Properties and Photo-Alignment in Bistable Nematic Liquid Crystal Displays

   Författare :Jesper Osterman; Claes-Göran Granqvist; Kent Skarp; Peter Raynes; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; LCD; liquid crystal; bistable; nematic; optical; modes; photo-alignment; Teknisk fysik; Engineering physics; Teknisk fysik;

   Sammanfattning : In recent years portable electronic devices, such as mobile phones and personal digital assistants, have increased the demand for high performance displays with low power consumption. An interesting candidate with the potential of fulfilling these demands is the reflective single-polarizer surface controlled bistable twisted nematic liquid crystal display. LÄS MER
