摘要： The electro-optical glare protection filter comprises a liquid crystal cell which is a laterally extended liquid crystal cell defining a volume between two laterally extended sides, the volume containing liquid crystals and having, in a vertical direction perpendicular to lateral directions, a thickness being smaller than an extension of the volume in any lateral direction. The FFS cell comprises a first electrode structure and a second electrode structure, which are arranged to change an orientation of the liquid crystals in the volume when a voltage is applied between them, wherein both the first and the second electrode structure are present at the same laterally extended side of the volume. The first electrode structure may comprise a plurality of electrically separate electrodes and the second electrode structure may comprise a plurality of electrode lines.

摘要： An automatic-darkening filter 10, 10′ that comprises a first polarizer 14, a second polarizer 18, a first liquid-crystal cell 16, and a sensor 64. The first polarizer 14 has a first polarization direction, and the second polarizer 18 has a second polarization direction. The liquid crystal cell 16 is disposed between the first and second polarizers 14, 18 and contains first and second optically-transparent, flexible, glass layers 40 and 42 with the liquid crystal layer 48 being located between these layers. The sensor 64 detects incident light and causes a signal to be sent, which causes molecular rotation within the liquid crystal layer. The inventive automatic-darkening filter is beneficial in that overall product weight can be reduced and the view field can be increased.

摘要： The present invention relates to an automatic welding filter that changes from a light transmission state to a dark transmission state in response to incident welding light and includes a colour-tunable filter whose spectral transmittance can be varied to optimise the visual appearance of a welding task. The colour-tunable filter comprises at least one low twist liquid crystal cell disposed between polarisation filters having substantially parallel polarisation directions. The user is able to adjust the colour of the automatic welding filter in the dark transmission state, independently of the shade, in response to a user selected colour signal which alters the birefringence properties of the low twist liquid crystal cell.

摘要： A method for operating an auto-darkening welding filter for protecting a welder's eye in the course of a pulse mode welding process. During the pulse mode welding process at least a first time interval with strong light emission and a second time interval with reduced and/or negligible light emission are repeated with a repetition rate, and a point in time of a beginning of the first time interval is associated with a raising edge event. The method includes the step of darkening the auto-darkening welding filter to a first darkening level at a point in time of the raising edge event that is associated with a next first time interval.

摘要： The welding filter device includes a light sensor, a microprocessor, a liquid crystal display, and a user interface. The light sensor senses light to generate a welding signal and a light source intensity signal. The microprocessor comprises a determining module, a control module, a regulating module, and a storage module. The determining module receives the welding signal and determines whether to activate a welding mechanism. The control module receives the light source intensity signal and outputs a control signal. The liquid crystal display presents a first display status according to the control signal. The user interface is used to generate a setting signal; wherein when the liquid crystal display presents the first display status, the regulating module receives the setting signal to regulate the settings so that the liquid crystal display presents a second display status. Furthermore, a method for controlling the welding filter device is also disclosed herein.
