DISPLAY AND CONTROL METHOD THEREOF

摘要

A display including: an LCD panel to display an inputted video signal from the outside; a middle level controller to increase a middle brightness signal level of the inputted video signal; a contrast controller to control a contrast of a video signal outputted from the middle level controller; a brightness mean calculating part to calculate a brightness mean of a video signal from one of the middle level controller and the contrast controller; and a controller controlling the contrast controller to control the contrast according to a result calculated by the brightness mean calculating part and a control method thereof. Thus, the contrast is controlled according to the brightness mean of one of the video signal having the controlled contrast and the video signal having the increased middle brightness signal level, which enables displaying an optimal image.
