AI Technical Summary

Benefits of technology

The solution effectively reduces light leakage and charge coupling, resulting in improved image quality by blocking unwanted light and minimizing irregular vertical crosstalk, thereby enhancing the overall luminance and clarity of the display.

Problems solved by technology

With the conventional LCD module of the above structure, light is apt to leak in the gap between the data line and pixel electrode to make poor image quality.
However, the black matrix may result in a smaller aperture ratio of the overall LCD module to decrease the luminance of the display resulting in poor image quality.
Namely, charge coupling between the data line and pixel electrode can occur causing irregular vertical crosstalk along the data line.

Abstract

A liquid crystal display panel with enhanced image quality is disclosed. The liquid crystal display panel has a plurality of gate lines, a plurality of data lines, a plurality of thin film transistors connected to gate line and data line, a plurality of pixel electrodes, and floating electrode(s). The floating electrode extends along the data line to prevent light leakage and vertical crosstalk. Throughout the whole liquid crystal display panel, the floating electrode is electrically interconnected to lessen vertical crosstalk.
