Abstract

Disclosed is an LCD (liquid crystal display) cell design that reduces the fragility of a cell by shifting the locations of the sealant. An LCD cell is made of two panels of glass, and glass fragmentation is said to occur as a result of micro-cracks. Therefore, all LCD cells are chamfered in the final process but, as the thick lines in Figure 1 shows, not every corner is chamfered. Figure 2 shows an example of an LCD cell using the disclosed new design. An epoxy adhesive is often used as a sealant in an LCD cell. Its mechanical strength is greater than that of glass, and it is thus possible to strengthen three out of four corners without chamfering. Therefore, LCD cells using the disclosed design have lower fragility, and greater robustness to variations in the positioning of the sealant.

New Sealant Design on Liquid Crystal Display

   Disclosed is an LCD (liquid crystal display) cell design
that reduces the fragility of a cell by shifting the locations of the
sealant.  An LCD cell is made of two panels of glass, and glass
fragmentation is said to occur as a result of micro-cracks.
Therefore, all LCD cells are chamfered in the final process but, as
the thick lines in Figure 1 shows, not every corner is chamfered.
Figure 2 shows an example of an LCD cell using the disclosed new
design.  An epoxy adhesive is often used as a sealant in an LCD cell.
Its mechanical strength is greater than that of glass, and it is thus
possible to strengthen three out of four corners without chamfering.
Therefore, LCD cells using the disclosed design have lower fragility,
and greater robustness to variations in the positioning of the
sealant.
