A method for applying an optical mark to a spectacle lens mounted in a spectacle frame includes determining an intended position of the optical mark at the spectacle lens based on the spectacle frame. The method further includes taking an image of at least a part of the spectacle frame and arranging the spectacle frame in a marking device having a marking appliance and adjusting the relative position of the spectacle frame and the marking appliance such that an actuation axis of the marking appliance intersects with the spectacle lens at the intended position of the optical mark. Additionally, the optical mark to the spectacle lens is applied at the intended position by using the marking appliance. The use of a spectacle frame as a positioning reference for an optical mark and a marking device are also disclosed.

A solar cell module includes: a solar cell module body and a print layer formed further toward a light-receiving surface side than the solar cell module body by printing with specific transparency in a specific region. A rear surface side is visible from the light-receiving surface side in at least part of the specific region. The specific transparency is set to satisfy a condition that spectral sensitivity integral ratio A defined by formula (1) below is not less than a specific value A* that the spectral sensitivity integral ratio A takes when printing is performed with transparency resulting in a short circuit current ratio of 0.6. λ is wavelength (nm), f(λ) is quantum efficiency IPCE (%) in a case in which the print layer is formed, and f.sub.SC(λ) is quantum efficiency IPCE (%) in a case in which the print layer is not formed.

A method of producing a spectacle lens includes providing a substrate having a front surface and a back surface and coating or covering at least one of the front surface or the back surface of the substrate, in full or in part, with a layer. The surface topography of the substrate surface is changed by bringing the surface into contact with a medium and the medium is removed. A product made according to the method and including (i) a spectacle lens or (ii) a representation of the spectacle lens in the form of computer-readable data present on a data medium or (iii) a data medium including a virtual representation of the spectacle lens in the form of computer-readable data or (iv) a representation of the spectacle lens in the form of a computer-readable data signal, is also disclosed.

A method of providing a light control member includes providing a plurality of barrier walls spaced apart from each other and defining a concave portion therebetween, providing a light control resin including a quantum dot in the concave portion, providing a first light having a wavelength equal to or greater than about 430 nanometers and equal to or smaller than about 500 nanometers to the light control resin, providing a second light having a wavelength shorter than the wavelength of the first light to the light control resin to which the first light is irradiated, and providing heat-treating the light control resin to which the second light is irradiated.

A LED display fabrication tool includes first and second dispensing chambers to deliver first and second color conversion precursors onto a workpiece for fabrication of a light emitting diode (LED) displays, first and second curing stations to cure the workpiece to form first and second color conversion layers over a first and second set of LEDs on the workpiece, and first and second washing/drying chambers to remove uncured portions of the first and second color conversion precursors from the workpiece and then dry the workpiece. Each of the chambers is independently sealable. A controller controls a workpiece transport system to move the workpiece sequentially between the chambers.
