A multi-screen display for rear projection applications includes a supporting structure and a screen comprising a plurality of screen panels which are positioned and attached to one another and to attachment plates by joining wires. The seams between the screen panels are minimal, specifically less than half of a millmetre wide, even in the event of relatively inaccurate installation of the projection screen, in spite of manufacturing tolerances and under changing climatological conditions, such as temperature and relative atmospheric humidity, owing to the fact that the attachment plates to which the screen panels are fixed using the joining wires are deformable and/or movably joined to the supporting structure.

The invention relates to a process for the preparation of monolithic xerogels and aerogels of silica/latex hybrids under subcritical conditions. In the two-stage synthesis of these alcogels in the presence of an acid-base catalyst, the hydrolysis and polycondensation of a silicon alkoxide are carried out in an organic medium containing excess water. A latex consisting of polybutyl methacrylate and polybutyl acrylate, modified with alkoxysilane groups, is first synthesized and then incorporated in the mixture either in the first stage in order to effect its co-hydrolysis with the silicon alkoxide, or in the second stage to effect its co-condensation with the previously hydrolysed colloidal silica. The resulting alcogels are aged, washed, and dried under subcritical conditions. This process gives hybrid products containing 0.1-50 wt-% of latex and having a density of 300-1300 kg/m3, a porosity of 40-85%, a specific surface area of 400-900 m2/g and a mean pore diameter of 2-12 nm. The products are resistant to atmospheric humidity and moisture, have better mechanical properties than the corresponding inorganic products, and can be used as thermal, acoustic and electrical insulators.
