  • Patent number: 10634966
    Abstract: A display substrate is disclosed, comprising a display area and a peripheral area surrounding the display area. The display substrate is fixed to a counter substrate in the peripheral area by a frame sealant. The display substrate comprises a substrate and a curing energy transmissive layer. A projection of the frame sealant on the substrate falls within or coincides with that of the curing energy transmissive layer. Since the curing energy transmissive layer transparent for the curing energy beam is provided in the display substrate, the frame sealant can be irradiated from the display substrate side through the curing energy transmissive layer, instead of from the counter substrate side. This improves the efficiency for curing the frame sealant. A display panel, a method for fabricating the display substrate and the display panel, and a display device are disclosed.

The method comprises irradiating predetermined regions of an optical, polymeric material with a laser to form refractive structures. To facilitate the formation of the refractive structures the optical, hydrogel polymeric material comprises a photosensitizer. The presence of the photosensitizer permits one to set a scan rate to a value that is at least fifty times greater than a scan rate without the photosensitizer in the material, yet provides similar refractive structures in terms of the observed change in refractive index. Alternatively, the photosensitizer in the polymeric material permits one to set an average laser power to a value that is at least two times less than an average laser power without the photosensitizer in the material, yet provide similar refractive structures.

The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

  • Publication number: 20110242631
    Abstract: A composition for producing optical elements having a gradient structure, particularly for holographic applications, is formed by a refractive index gradient. The composition is produced from one or more polymerizable and/or polycondensable monomers and at least one biological polymer. A potential difference is generated for the directed diffusion of the monomers by inducing a local polymerization or polycondensation. The result is the formation of a refractive index gradient.

  • Patent number: 7973094
    Abstract: A metal nanoparticle supported on or dispersed in a polymer is irradiated with photons from a laser source to address the nanoparticles. The polymer is transmissive to the photons and addressed nanoparticles transform the energy of the photon to heat which is transferred to a material in the vicinity of the nanoparticle. The locally heated material undergoes a physical or chemical transformation upon heating. The transformed material can be a material in the proximity of the metal nanoparticle supported polymer or metal nanoparticle/polymer composite. In this manner thermally induced physical or chemical transformations can be carried out in very small volumes of material without significant heating to the bulk of the material.
