1 V I T S W E L L L o o k f o r a N e w A n g l e The New Standard of PDLC Technology

2 PDLC FILM Technology PDLC(Polymer-Dispersed Liquid Crystal) is smart window film technology, based on material which mixes Polymer and Liquid Crystal. When electricity is powered on PDLC film, the film becomes transparent, hence users can control its opacity / clarity by simple switchable device. Power ON Power OFF Power Off : Irregular arrangement of crystal polymer makes scattering of light phenomenon Power On : Regular arrangement of crystal polymer makes light transmission phenomenon

3 Developing Polymer & Liquid Crystal function 99% UV Block PDLC + PDLC + 86% IR Block Become available for shading products by enhancing UV & IR block function and durability Technology Operation Mode Operation Technology Specifications Power On: Clear/ Power Off: Opaque Power On: Section Division -20 ~100

4 New Product Line-Up from Vitswell PDLC 1. PDLC Standard 2. PDLC+ HT (High-Transmittance) 3. PDLC+ HR (Heat-Resistant)

5 1.0 PDLC Standard Due to our constant development, we have made our PDLC film thiner than the other PDLC film. This thin film characteristic helps easy cutting and convenient installation for PDLC film operation. Protective Film ITO(pet) Film Polymer Mixture ITO(pet) Film Protective Film 0.5mm 0.225mm 0.325mm 0.225mm for Normal Type 0.325mm for Sticky Type Protective Film ITO(pet) Film Polymer Mixture ITO(pet) Film Protective Film Rigid Flexible

6 2.0 PDLC + HT (High-Transmittance) Film State: ON Side Front Side Side Front Side PDLC Standard PDLC + HT Haze level 5~6 during ON state PDLC standard viewing angle issue: exsistent Side visibility: Bad Reduced Haze level as 2 during ON state PDLC standard viewing angle issue: improved Side visibility: Good

7 2.0 PDLC + HT (High-Transmittance) Side Front Side Film State: ON PDLC : PDLC Standard PDLC + : PDLC + HT

8 3.0 PDLC + HR (Heat-Resistant) 90 PDLC becomes clear in spite of OFF state as temperature rises since it s weak for temperature durability. PDLC + keeps OFF state until 100 so it is able to work for more variable application including outdoor area. Film State: OFF PDLC : PDLC Standard PDLC + : PDLC + HR

9 Key Technology 1. Discoloring Test, caused by UV exposure PDLC + other PDLC Film QUV Test conditions Exposure time : 500 hours / Level of Irradiance : 700mw/ m2 / UV LAMP : UVA -320nm Cylcle : 8 hours under UV irradiation at 60, 4 hours condensation at 50 / Test standard : ASTM G 154:2012

10 Key Technology 2. High Transmittance Due to Polymer & Liquid Crystal development, we reduced haze level for the front view and side view as well. Users are able to enjoy much more clear view, compared to other PDLC film. Power : ON PDLC + : Vitswell PDLC PDLC : Other PDLC Film Division Haze(OFF) Haze(ON) PDLC + 90±1 2±1 PDLC 91±1 5±1

11 Key Technology 3. Temperature Durability The other PDLC film becomes clear in spite of OFF state as temperature rises with poor temperature durability. PDLC + keeps OFF state until 100 hence is able to work for outdoor application as well. Power : OFF Japan A** 71 Korea D** PDLC : Other PDLC Film PDLC + : Vitswell PDLC 63
