Problem:

Industry urgently needs a thin and durable coatable polarizer for foldable and rollable OLED including Mobile, Tablet, PC and TV devices, earmarked for introduction in 2021.

Circular polarizer film needs to meet static bending test with no deformation. Current PVA-base POL would be peeled after rolling test.

Solution:

Light Polymers’ Polymer Polarizer successfully coated onto retarder films and cover films with OCA capped on top to achieve thinnest structures. Samples have passed initial RA and bend tests by several customers.

Application:

Direct coat polarizer on cover or retarder film to solve the deformation issue of PVA-based polarizers and enable new device form factors.

Specifications: TT: 40%, PE: 98%, R<6%, folding 2 mm (200k cycles)

Application Structure: Direct coating polarizer on retarder film (Structure 1) or on cover film (Structure 2)

Problem:

Looking for thin and durable coatable polarizer for stretchable applications in personal wearable device, display integrated in steering whee, etc.

Circular polarizer film needs to meet static bending test with no deformation. Current CPOL substate (TAC) would be broken after 4% stretching.  

Solution:

Light Polymers’ Polymer Polarizer has been coated successfully onto our selected cover film to become coating-type circular polarizer film to achieve thinnest structure.  Sample has passed initial RA and bend test and meets minimum optical performance. 

Application:

Direct coat polarizer on cover or retarder film to solve the deformation issue of PVA-based polarizers and enable new device form factors.

Specifications: TT: 40%, PE: 98%, R<6%, folding 2 mm (200k cycles)

Application Structure: Direct coating polarizer on cover film (Structure 1)

Problem:

Current after-market privacy display is not favorad by customers due to its thickness.

A built-in switchable solution is therefore proposed, where user can switch between normal display screen and privacy view screen.

Solution:

Light Polymers’ Polarizer solution is the thinnest in the industry (26um total without adhesive). It has good thermal stability (1,000 hours at 95ºC), good environmental durability (Passed 500 hours at 60ºC/90%rh) and was successfully coated onto retarder films and cover films with OCA capped on top to achieve thinnest structures. 

Application:

Add a 3rd or 4th polarizer layer to make a privacy cell with minimum thickness added. Current PVA based polarizer film is 120 um.

Specifications: PE: > 97% at 550 nm (TT:41-42%)

Application structure: Extra privacy cell inserted in existing LCD panel

Problem:

WGP is too expensive to be implemented to the commercial product.

The yield of conventional PVA polarizer lamination on wafer is too low.

Solution:

Direct coating of Light Polymers’ polarizer on wafer would enable a simpler process, better yield, and greater functionality integration in the future. The high temperature resistance our lyotropic liquid crystals ensures endurance during post process (>30 min at 150ºC).

Application:

Coating type polarizer on wafter to replace very expensive solution such as WGP for camera sensor, display sensor and other applications

Specifications: PE: > 99% (Tpar: Tper > 200:1)

Application structure: Direct coating polarizer on circuit wafer

Problem:

Application:

Directly coating our polarizer to be  third polarizer layer to significantly enhance contrast ratio for large-size LCD TV.

Specifications: Contrast ratio (Tpar/Tper) > 1.3 times than conventional polarizer

Application structure: Direct coating polarizer on color filter

Problem:

In 8k large size TV panels, TFT LCD companies are trying to develop new technology to compete against OLED TV.

A polarizer solution with simple manufacturing process, UV blocking properties and high temperature resistance is what LCD manufacturers are looking for.

Solution:

Light Polymers’ Polymer Polarizer is the thinnest polarizer solution available. With great potential for direct coating on other optical layers and films, and outstanding durability (1,000 hours at 95ºC), our lyotropic liquid crystal polarizers are the prime choice for Mini–LED LCD displays .

Application:

Direct coat polarizer on mini-LED LCD displays to reduce overall display thickness.

Specifications: PE> 99.9%

Application structure: Coating polarizer to replace current bottom polarizer

Problem:

Automotive market is lookin into adopting smart windows for side windows and sunroof applications to improve passenger comfort.

Competitive technology is SPD(Suspended particle device) which has several issues, being expensive ($700/m²), bluish, low transmittance range (5~50%) and high voltage driving (100V).

Solution:

Light Polymers’ lyotropic liquid crystals can be combined with the existing smart window technology (coating of cholesteric liquid crystals) between ITO coated films. The driving voltage is less than 10V and forward-thinking Korean car manufacturers are interested to apply this technology for their side windows and sunroof.

The required thickness is less than 200um for the smart window, making coated polarizer technology is indispensable.

Application:

Coating lyotropic liquid crystal polarizer on the backside of ITO-coated film for smart window, to be applied on automotive side windows and sunroof.

Specifications: TT: 40%, PE: 98% 

Application structure: Encapsulation PP001 coated smart window film with automotive side window glass.
