Embodiment Construction

[0045] exist figure 1 A support piece 1 can be seen in the figure, and a very thin substrate 2 is connected to the support piece. The thickness of the ultra-thin substrate is much thinner than that of the support sheet. The very thin substrate can be, for example, a flexible substrate for liquid crystal display production (LCD-Displayherstellung). According to the invention, a spacer layer 3 is provided between the very thin substrate and the support sheet. The spacer layer 3 is made up of individual spacers 3.1 spaced apart from each other so that between the individual spacers 3.1 there are grooves 5 which reduce the pressure on the very thin substrate. 2 Adhesion when lifted from support sheet 1.

[0046] At the same time, the overall thickness is determined to a constant dimension by the selection of the thickness dA of the individual spacers 3.1 and the thickness of the support sheet or spacer layer. If the thickness of the spacer layer is small, for example in the ra...

Abstract

The invention relates to a composite part comprising a substrate, especially an extremely thin substrate with a thickness of less than 0.3 mm, and a support piece, wherein the base piece is at least indirectly detachably connected to the support piece. In the present invention, a spacer layer with grooves is inserted between the substrate and the support plate, wherein the grooves are provided at least on that surface of the spacer layer facing the substrate.

Description

technical field [0001] The invention relates to a composite part comprising a substrate, especially a very thin substrate, and a carrier sheet. There, the substrate and the support sheet are connected to each other so as to form a stable self-supporting structure. Specific substrates, for example made of glass or a glass-containing material, with a thickness of less than 0.3 mm are referred to below as ultra-thin substrates. Background technique [0002] In the display industry, according to the standard, glass with a thickness of 0.3-2mm is currently used to manufacture displays, especially for mobile phones and PDAs. Displays will use glass with a thickness of 0.7mm and 0.5mm (0.4mm). These glasses are hard, self-supporting, and display manufacturing equipment is optimized for such thicknesses. [0003] However, if an ultra-thin substrate such as a glass film or a polymer film with a thickness of less than 0.3 mm is used for digital or analog displays that have the advan...
