Abstract: The present invention relates to an intelligent display panel device and method that can adjust its luminosity according to changing ambient light. The device first uses its built-in light detectors to obtain both external and internal luminosity values. A microcomputer system then goes on to compare the values and compute a proper value for adjusting the display panel luminosity. The value is then passed to an internal luminosity converter which first converts the value into a series of signals and then transmits the converted signals to a built-in Luminosity Control Module that will adjust the luminosity of the display panel according to this value. With the present invention, computer users won't have to manually adjust the luminosity of the display panel. The method will compare internal and ambient light and compute an optimum display panel luminosity value in response to changes in the ambient light.
