Abstract: A light source device includes a light source module having a light-emitting block, an image analysis part, a duty ratio calculation part, a duty ratio determination part and a signal generation part. The image analysis part extracts representative luminance data of the light-emitting block based on pixel data. The duty ratio calculation part calculates duty ratio data of the light-emitting block based on the representative luminance data. The duty ratio determination part generates determined duty ratio data of the light-emitting block based on the duty ratio data from a first period, and the signal generation part generates a driving signal having a duty ratio corresponding to the determined duty ratio data to drive the light-emitting block.

Abstract: A display apparatus includes: a display panel which displays an image based on a display mode; a data driver which provides data signals to the display panel; a gate driver which starts an operation thereof in response to a start signal, and comprises stages and at least two dummy stages, where the stages sequentially provides gate signals to the display panel; and a timing controller which selects a signal from the start signal and a reset signal based on the display mode and outputs the selected signal selected to the at least two dummy stages, where each stage receives a clock signal, a previous carry signal from a previous stage, a first subsequent carry signal from a first subsequent stage and a second subsequent carry signal from a second subsequent stage, and outputs a corresponding gate signal of the gate signals and a carry signal.
