Computer program, method, and device for controlling the brightness of a display

A method of controlling the brightness of a display, the display including a back light and a display module having an array of pixels that may be individually controlled to selectively block or pass light from the back light to create a desired image, the method comprising the steps of:

• adjusting the brightness of the back light to vary the amount of light passing through the pixels of the display module to control the brightness of the image;
• and
• when the back light has been dimmed to a pre-determined brightness level, adjusting the luminosity of the pixels to further reduce the amount of light passing through the pixels to reduce the brightness of the image.

A computer program stored on computer-readable medium for controlling the brightness of a display, the display including a back light and a display module having an array of pixels that may be individually controlled to selectively block or pass light from the back light to create a desired image, the computer program including code segments for:

• adjusting the brightness of the back light to vary the amount of light passing through the pixels of the display module to control the brightness of the image;
• and
• when the back light has been dimmed to its approximate lowest brightness level, modifying luminosity of the pixels to further reduce the amount of light passing through the pixels to reduce the brightness of the image.
