Samsung patents display layer that narrows viewing angle for touch screens
Samsung describes a display structure where a masking layer sits above the pixels to limit how wide the viewing angle is for specific areas. This design places the touch sensor between the mask and a transparent layer, with the sensor's insulating material removed under the light-passing sections to improve performance.
In the filing’s own words
This display device comprises a pixel layer including a plurality of pixels that include a first pixel and a second pixel positioned adjacent to the first pixel, black matrix parts, and a light transmission part disposed to emit light from the first pixel at a first viewing angle limited by some of the black matrix parts and emit light from the second pixel at a second viewing angle limited by some of the black matrix parts, wherein the second viewing angle includes a masking layer that is narrower than the first viewing angle, a transparent layer disposed between the pixel layer and the masking layer such that the masking layer is spaced a designated distance apart from the pixel layer for the second viewing angle, and a touch layer which is disposed between the masking layer and the transparent layer and which includes an insulating layer and a plurality of touch sensing electrodes, the insulating layer of the touch layer being omitted below the light transmission part of the masking layer.
What exactly they claim (claim 1)
1. A display device comprising: a pixel layer comprising a plurality of pixels including a first pixel and a second pixel positioned adjacent to the first pixel; a masking layer including black matrix (BM) portions and light transmittance portions disposed such that light from the first pixel is emitted with a first viewing angle limited by a portion of the BM portions and light from the second pixel is emitted with a second viewing angle limited by a portion of the BM portions, the second viewing angle being narrower than the first viewing angle; a transparent layer disposed between the pixel layer and the masking layer such that the masking layer is spaced apart by a specified distance from the pixel layer for the second viewing angle; and a touch sensitive panel (TSP) layer, disposed between the masking layer and the transparent layer, including an insulation layer and a plurality of touch sensitive electrodes, wherein the insulation layer of the TSP layer is omitted beneath the light transmittance portions of the masking layer.
