Abstract

Disclosed is a High-aperture ratio Thin Film Transistor/Liquid Crystal Display (TFT/LCD) pixel structure which has electrical floating metal running parallel to the Signal-line. This metal assists the aperture ratio up because it shields the Back-Light and reduces the color-filter Black-Matrix area. The first purpose of electrical floating is never to make a narrow Sub-capacitor area which is easy to change by process vibration. The second purpose is reducing the line-defect.

Thin Film Transistor Pixel Design with Floating Metal

      Disclosed is a High-aperture ratio Thin Film Transistor/Liquid
Crystal Display (TFT/LCD) pixel structure which has electrical
floating metal running parallel to the Signal-line.  This metal
assists the aperture ratio up because it shields the Back-Light and
reduces the color-filter Black-Matrix area.  The first purpose of
electrical floating is never to make a narrow Sub-capacitor area
which is easy to change by process vibration.  The second purpose is
reducing the line-defect.
