Abstract

Official abstract text for this publication.

A liquid crystal display is disclosed. The liquid crystal display includes a power module, which senses an input voltage and outputs a mode conversion signal when the input voltage is equal to or less than a reference voltage, and a timing controller which changes a driving mode of a source driver integrated circuit (IC) in response to receiving the mode conversion signal from the power module.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid crystal display comprising: a power module configured to sense an input voltage and output a mode conversion signal when the input voltage is equal to or less than a reference voltage; and a timing controller configured to select one of a high impedance mode and a charge share mode in response to receiving the mode conversion signal, and to change a driving mode of a source driver integrated circuit (IC) in response to receiving the mode conversion signal from the power module. 2. The liquid crystal display of claim 1 , wherein the power module includes: a reference voltage generator configured to generate the reference voltage; and a comparator configured to receive the reference voltage and the input voltage and output the mode conversion signal when the input voltage is equal to or less than the reference voltage. 3. The liquid crystal display of claim 1 , wherein the timing controller changes a polarity inversion period in response to receiving the mode conversion signal. 4. The liquid crystal display of claim 3 , wherein the timing controller selects one of a horizontal 1-dot inversion scheme and a horizontal 2-dot inversion scheme in response to receiving the mode conversion signal. 5. The liquid crystal display of claim 3 , wherein the timing controller selects one of a vertical 1-dot inversion scheme and a vertical 2-dot inversion scheme in response to receiving the mode conversion signal.
