Abstract:
1. A liquid crystal display (LCD) device, comprising: a scaler configured to generate an input image by adjusting a resolution of a received image signal to be a resolution of an LCD panel; a brightness extractor configured to separate a brightness and a color difference information from the input image received from the scaler; an average picture level (APL) restrictor configured to: an interface board configured to receive the RGB data from the APL restrictor via a first low-voltage differential signaling (LVDS) interface receiving circuit; and a driving circuit configured to: wherein the limit APL is decided by a selection of a user via a software input, wherein the limit APL from the user is input to the APL restrictor from the software input, and wherein the APL restrictor is further configured to, when the APL of input image is lower than the limit APL:
