Abstract

A conventional liquid crystal display (LCD) LCD manufacturing technology restricts the glass assembly with a glass substrate LCD is shown in substrate LCD to a minimum thickness of 0.5 mm. Figure 1. Thickness of the conventional LCD and Hence, thickness of the conventional LCD assembly backlight assembly is due to the glass substrate can be reduced using a plastic LCD with gratings LCD and a light diffuser, Current constraints in for light diffusion.

PLASTIC LCD WITH GRATINGS AS A BACKLIT DISPLAY PANEL

by Phang Kien Yip

INTRODUCTION

  A conventional liquid crystal display (LCD) LCD manufacturing technology restricts the glass assembly with a glass substrate LCD is shown in substrate LCD to a minimum thickness of 0.5 mm. Figure 1. Thickness of the conventional LCD and Hence, thickness of the conventional LCD assembly backlight assembly is due to the glass substrate can be reduced using a plastic LCD with gratings LCD and a light diffuser, Current constraints in for light diffusion.

DESIGN DESCRIPTION

Shown in Figure 2 is a plastic LCD with a as to provide better contrast for displaying on the reflector replacing the light diffuser of Figure 1. plastic LCD.

The reflector is formed with an opaque material so

Technical Developments

In addition, the plastic LCD has gratings on gratings allow uniform light dispersion and a bottom surface, as shown in Figure 3. These propagation.

CONCLUSION

  Plastic LCDs may cost more than glass costs. The plastic LCD assembly, as described substrate LCDs at present. However, considering above, has better durability with good contrast for costs of replacing conventional LCD assemblies displays provided by the reflecto...
