VIDEO DISPLAY DEVICE Russian patent published in 2013 - IPC H04N9/68 

FIELD: radio engineering, communication.

SUBSTANCE: video processing circuit (2) reduces and corrects the signal value of the input video signal, which represents the colours within the colour range to be corrected, which is within a specified saturation range from the highest saturation to the middle saturation inside a specified hue range centred on the red hue in the colour reproduction range (an expanded colour reproduction range wider than the sRGB standard colour reproduction range) of a liquid crystal panel (4), and which is within a specified brightness range from the highest brightness to the middle brightness inside that range, so that the saturation and brightness thereof change to saturation and brightness within a predetermined middle colour range between the expanded colour reproduction range and the colour reproduction range of the standard to which the input video signal complies.

EFFECT: displaying highly saturated and bright red hue on a display with a wide colour gamut, while eliminating the problem of seeing glaring images in the part of the red colour region near the highest brightness and saturation when displaying video based on a video signal which complies with a narrower colour reproduction range standard.
