Abstract

Disclosed is a cell press method without spacer contacting with cell surface to prevent mechanical damages on the cell surface such as scratches and dimples, and it will eliminate the spacer cost for the process. Conventional spacer is made by solid material or artificial cloth and it often causes the mechanical damages during cell press process. On the other hand, this new method utilizes compressed air to press cell instead of the conventional spacers as contact material and it also reduces the process cost of spacer as consumption material.

Spacerless Cell Press Method

      Disclosed is a cell press method without spacer contacting with
cell surface to prevent mechanical damages on the cell surface such
as scratches and dimples, and it will eliminate the spacer cost for
the process.  Conventional spacer is made by solid material or
artificial cloth and it often causes the mechanical damages during
cell press process.  On the other hand, this new method utilizes
compressed air to press cell instead of the conventional spacers as
contact material and it also reduces the process cost of spacer as
consumption material.

      Fig. 1 shows the press holder consists of a frame and two inner
seals to maintain the hermeticity of compressed air when a cell is
put between two press holders.  Fig. 2 shows the press method by
using the press holders.  The press holders and cells are stacked
alternately between two rigid fixtures and compressed air is supplied
through the air supply ports on the press holder frame.  Thus, the
cell pixel area can be pressed by controlled air pressure instead of
direct contact force.

      Since the press holder has rigid frame construction, this
method can be enhanced to process automation by modification with
sliding mechanism to the press holder.
