Display method, display controller, and display apparatus

A display controller for use with a display device and a light source, said display controller comprising:

• a video signal-analyzing unit operable to receive and analyze a video signal, and to generate adjustment parameter information and light source light-emitting amount information;
• a video signal-adjusting unit operable to receive the video signal, adjust the video signal in accordance with the adjustment parameter information from said video signal-analyzing unit, and to feed the adjusted video signal into the display device;
• and
• a light source-controlling unit operable to regulate a light-emitting amount of the light source in accordance with a value of maximum luminance of the video signal, and to feed a light source-controlling signal into the light source in accordance with the light source light-emitting amount information from said video signal-analyzing unit, the regulated light-emitting amount including 0%, 100% and a value therebetween,
• wherein said video signal-analyzing unit synchronizes a timing at which the display device is to display a picture based on the adjusted video signal from said video signal-adjusting unit, with a timing at which the light source is to change the regulated light-emitting amount in response to the light source-controlling signal from said light source-controlling unit, and
• wherein said video signal-adjusting unit adjusts transmissivity of the display device in accordance with the regulated light-emitting amount in a manner such that the transmissivity of the display device increases and the regulated light-emitting amount decreases.

A display apparatus comprising:

• a display device;
• a light source;
• and
• a display controller comprising:
• a video signal-analyzing unit operable to receive and analyze a video signal, and to generate adjustment parameter information and light source light-emitting amount information;
• a video signal-adjusting unit operable to receive the video signal, adjust the video signal in accordance with the adjustment parameter information from said video signal-analyzing unit, and to feed the adjusted video signal into said display device;
• and
• a light source-controlling unit operable to regulate a light-emitting amount of the light source in accordance with a value of maximum luminance of the video signal, and to feed a light source-controlling signal into said light source in accordance with the light source light-emitting amount information from said video signal-analyzing unit, the regulated light-emitting amount including 0%, 100% and a value therebetween,
• wherein said video signal-analyzing unit synchronizes a timing at which said display device displays a picture based on the adjusted video signal from said video signal-adjusting unit, with a timing at which said light source changes the regulated light-emitting amount in response to the light source-controlling signal from said light source-controlling unit;
• wherein said video signal-adjusting unit adjusts transmissivity of said display device in accordance with the regulated light-emitting amount in a manner such that the transmissivity of the display device increases and the regulated light-emitting amount decreases;
• wherein said display device is operable to display a picture in accordance with the adjusted video signal that is fed from said video signal-adjusting unit of said display controller;
• and
• wherein said light source is operable to illuminate said display device with light in accordance with the light source-controlling signal that is fed from said light source-controlling unit of said display controller.
