To align a display substrate comprising an array of pixels with a component substrate comprising an array of optical components, the display substrate is divided from a display motherglass formed with an array of panels each comprising an array of pixels sufficient for a single display substrate and with, in respect of each panel, a first alignment feature having a surface relief aligned with the array of pixels. The component substrate is formed with an array of optical components and a second alignment feature aligned with the array of optical components, the second alignment feature having a surface relief shaped to register with the first alignment feature. The display substrates is attached to the component substrate with the first and second alignment features in registration with each other. The alignment of the first alignment feature with the array of pixels may be carried out at the motherglass stage in respect of the entire motherglass. The registration of the alignment features during attachment is a straightforward mating process which does not require precision alignment apparatus. Thus the yield can be increased.
A method of aligning display substrates comprising an array of pixels with component substrates comprising an array of optical components, the method comprising:
A display apparatus comprising a display substrate comprising an array of visible pixels attached to a component substrate comprising an array of optical components, wherein the display substrate has a first alignment feature arranged outside the array of visible pixels and, aligned with the array of visible pixels, the component substrate has a second alignment feature aligned with the array of optical components, and the first and second alignment features have respective surface reliefs in registration with each other.
A display substrate comprising an array of pixels for attachment to a component
A component substrate comprising an array of optical components for attachment to a display substrate comprising an array of visible pixels and a second alignment feature arranged outside the array of optical features to be aligned with the array of visible pixels of the display substrate and having a surface relief aligned with the array of optical components.
A display motherglass comprising an array of panels each comprising an array of visible pixels sufficient for a single display substrate and with, in respect of each panel, a first alignment feature having a surface relief arranged outside the array of visible pixels and aligned with the array of visible pixels.
A component motherglass comprising an array of panels each comprising an array of optical components sufficient for a single component substrate for attachment to a display substrate comprising an array of visible pixels, and, in respect of each panel, a second alignment feature arranged outside the array of optical features to be aligned with the array of visible pixels of the display substrate and aligned with the array of optical components.
