Abstract

Disclosed is a design for an LCD (liquid crystal display) module becomes smaller and more reliable to reverse an LCD cell. Figure shows the example of this new LCD module design. Main features are as follows, 1. The LCD cell is designed to reverse the TFT (thin film transistor) glass and the CF (color filter) glass. Then, the TAB (tape automated bonding) film is able to bend shorter than outline of the TFT glass. 2. The tapered off rubbers which are little thicker than thickness of the polarizer are sandwiched between the metal bezel and the glasses of the LCD cell, and the rubbers are able to sandwich at four all sides. Then, the glasses as the most fragile article in the LCD module are able to contact with the rubbers to X, Y, and Z all directions.

LCD Module Design Reversed LCD Cell

   Disclosed is a design for an LCD (liquid crystal display)
module becomes smaller and more reliable to reverse an LCD cell.
Figure shows the example of this new LCD module design.  Main
features are as follows,
  1.  The LCD cell is designed to reverse the TFT (thin film
      transistor) glass and the CF (color filter) glass.  Then,
      the TAB (tape automated bonding) film is able to bend
      shorter than outline of the TFT glass.
  2.  The tapered off rubbers which are little thicker than
      thickness of the polarizer are sandwiched between the
      metal bezel and the glasses of the LCD cell, and the
      rubbers are able to sandwich at four all sides.  Then,
      the glasses as the most fragile article in the LCD
      module are able to contact with the rubbers to X, Y,
      and Z all directions.  (The current design is contacted
      only Z-direction, moreover by two sides.)

   Therefore, an LCD module using this new design is possible
to be smallest size and more reliable for the mechanical strength.
