AI Technical Summary

Benefits of technology

The photosensitive material effectively forms a flexible substrate that maintains stability and design flexibility, overcoming the limitations of conventional plastic substrates by providing enhanced temperature resistance and preventing oxygen and moisture infiltration, thus enabling the production of thinner, more impact-resistant, and lighter flexible LCDs.

Problems solved by technology

The currently available liquid crystal display (LCD) technologies employ passive scan or active matrix to display images, which however requires considerable thickness stability for precision control.
Otherwise even slight deformation will lead to serious image distortion.
But in processes with temperature of 200° C. or higher, plastic material is prone to deformation or even decomposition, hence limiting its dimensions and applications.

example 1

Preparation of Photosensitive Material (I)

[0029] After mixing modifier Zonyl FSO (DuPont) at 0.1 wt % of photosensitive material and photosensitive material Norland Optical Adhesive 65 (NOA-65, Norland), apply the mixture to 50 μm PET film with 4# wire rod (9 μm) or dip coat the mixture on glass. Subject the mixture to irradiation of 365 nm ultraviolet light for 5 seconds, then measure its contact angle. The results are presented in Table 1.

example 2

Preparation of Photosensitive Material (II)

[0030] After mixing modifier BYK333 at 1.5 wt % of photosensitive material and photosensitive material NOA-65, apply the mixture to 50 μm PET film with 4# wire rod (9 μm) or dip coat the mixture on glass. Subject the mixture to irradiation of 365 nm ultraviolet light for 5 seconds, then measure its contact angle. The results are presented in Table 1.

example 3

Preparation of Photosensitive Material (III)

[0031] After mixing modifier BYK333 (BYK Chemie USA Inc.) at 1.0 wt % of photosensitive material , Surfynol OP340 (Air Products and Chemicals, INC) at 0.5 wt % of photosensitive material, and photosensitive material NOA-65, apply the mixture to 50 μm PET film with 4# wire rod (9 μm) or dip coat the mixture on glass. Subject the mixture to irradiation of 365 nm ultraviolet light for 5 seconds, then measure its contact angle. The results are presented in Table 1.

Abstract

The present invention provides a photosensitive material for non-substrate liquid crystal display. This photosensitive material includes photo-initiator selected from the free-radical type or cation type photo-initiator or mixture thereof, photosensitive polymerizable monomers or oligomers selected from the group consisting of double-bond compounds, compounds having epoxy functional group and mixtures thereof, and modifier selected from the group consisting of long-alkyl-chain functional group, silicone-alkyl compounds, double-bond compounds and mixtures thereof. The photosensitive material can surround liquid crystal display cell and separate from assisting substrates that a non-substrate liquid crystal cell surrounded by photosensitive material is acquired.

Description

CROSS REFERENCES TO THE RELATED APPLICATIONS [0001] This is a Continuation-in-part of U.S. application Ser. No. 10 / 792,813, filed Mar. 5, 2004, currently pending.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a photosensitive material for fabricating a flexible substrate used for non-substrate liquid crystal display that can separate from assisting substrates. [0004] 2. Description of the Related Art [0005] The application of flat panel display (FPD) has helped reduce the weight and volume of display. The currently available liquid crystal display (LCD) technologies employ passive scan or active matrix to display images, which however requires considerable thickness stability for precision control. Otherwise even slight deformation will lead to serious image distortion. To bring about thinner and more impact-resistant FPD, some of the FPD technologies for conventional glass substrate process have shifted focus to the R&D of plast...
