Abstract
Official abstract text for this publication.
A display panel has an amorphous silicon gate driver. A variable capacitor is formed at one end of a gate line to prevent the deterioration of display quality due to high temperature noise. A predetermined level of capacitance is provided to the variable capacitor to the reduce ripple of gate voltage and eliminate the high temperature noise.
First claim
Opening claim text (preview).
What is claimed is: 1. A display panel, comprising: a display area that includes a gate line, the gate line having electrical characteristics comprising a gate line resistance and a gate line capacitance; a main gate driver that is connected to one end of the gate line, that applies a gate on voltage to the gate line, and is integrated on a substrate; and a sub gate driver that is connected to an other end of the gate line and includes at least one variable capacitor, wherei…
