Title:
COLORED PLATE-SHAPED COMPONENT WITH STRUCTURED COVER PLATE AND COLOR FILTER LAYER
Document Type and Number:
WIPO Patent Application WO/2021/151374
Kind Code:
A1
Abstract:
The invention relates to a plate-shaped component (1) comprising a transparent cover plate (2) and a planar back element (3) attached to the cover plate (2), wherein the cover plate (2) has a front surface (4) facing the external environment and a back surface (5) facing the back element (3), wherein at least one surface (4, 5), selected from front and back surfac-es, has at least one structured region (8, 8'), and wherein at least one color filter layer (9, 9') for reflecting light within a predetermined wavelength range is arranged on at least one surface (4, 5), selected from front and back surfaces, - wherein the at least one structured region (8, 8') has the following features i) to iii) : i) perpendicular to the plane of the cover plate (2), a height profile comprising peaks and valleys, a mean height difference between the peaks and valleys being at least 2μm, ii) at least 50%of the structured area is composed of segments which are inclined with respect to the plane of the cover plate (2), wherein, with respect to the plane of the cover plate (2), at least 20%of the segments have an angle of inclination in the range from greater than 0° to a maximum of 15° and at least 30%of the segments have an angle of inclination in the range from greaterthan 15° to a maximum of 45°, wherein iii) the segments are each planar and have a segment area of at least 1μm 2, the seg-ments each having an average roughness of less than 15%of a layer thickness of the at least one color filter layer (9, 9'); and - wherein the at least one color filter layer (9, 9') contains at least one highly refrac-tive layer, the at least one refractive layer having a refractive index of greater than 2.5 in the wavelength range from 400 nm to at least 700 nm and an extinction coefficient of at least 0.2 below 450 nm and less than 0.2, in particular less than 0.1, above 700 nm.
