    Abstract: A tiled display having pixels arranged in rows and columns, and including first and second tiles. The tiles comprise a substrate carrying a matrix of pixels arranged at a pixel pitch. The substrates comprise an edge extending between opposing faces in a depth direction. The substrate edges have a complementary shape, and face one another to establish a seam. The pixel pitch is maintained across the seam. Pixels of the second tile are not interposed between pixels of the first tile. The complementary shape includes a segment of the seam being oblique to the pixel rows, or the substrate edge of the first tile profiled in the depth direction whereby at least a section of the edge is non-perpendicular to the faces. The tiled display can maintain the pixel pitch at the seams at high resolutions (e.g., pixel pitch less than 0.5 mm).

    Abstract: A fluidic module includes a monolithic closed-porosity ceramic body that has a first region and a second region with the first region disposed between the second region. The first and second regions are configured to differ from one another with respect to a common attribute of a ceramic material of the ceramic body. The common attribute can differ by forming the first and second regions from ceramic particles that differ with respect their particle sizes. The fluidic module further includes a tortuous fluid passage that extends through the ceramic body. The fluid passage is surrounded by the first region such that the fluid passage is separated entirely from the second region at least within a planar region of the ceramic body. The fluid passage has an interior surface with a surface roughness of less than or equal to 5 μm Ra. A method for forming the fluidic module is disclosed.

    Abstract: A module and process for forming a ceramic fluidic module (300) that includes a unified closed-porosity ceramic body (200) and a tortuous fluid passage (P) that extends through the body (200). The body (200) has a first mean density within a first layer (222) that is greater than a second mean density within a second layer (226). The first and second layers (222, 226) are axially serially arranged between opposed major surfaces (228, 229) of the body (200). The fluid passage (P) adjoins the first layer (222) of the body (200). The process includes pressing a first volume of ceramic powder (120) to form a pre-pressed body (150). A passage mold (130) is then positioned on the pre-pressed body (150). The pre-pressed body (150) and the passage mold (130) are then covered with a second volume of ceramic powder (125). The body (150), the mold (130), and the second volume of ceramic powder (125) are then pressed to form a pressed body (160). The pressed body (160) is heated and sintered to form the ceramic fluidic module (300).
