Abstract
A liquid crystal display in which the construction of an inverter is not complex and which can change the luminance wider than the changeable range of regulating light of the inverter is provided. An image is formed at a display control circuit and the gradations of the image is converted at a luminance regulating circuit and the converted image is inputted to a liquid crystal display section. The liquid crystal display section displays the image on a panel controlling by image data inputted a backlight which is controlled by changing an effective value of a tube current in an inverter. The luminance regulating circuit controls display gradations responding to a user setting value.
Claims8
A liquid crystal display which regulates the light of a backlight disposed at the back of a liquid crystal display section using a regulating current type inverter, comprising:
- a luminance regulating means for controlling a display luminance of display data at said liquid crystal display section, by changing gradations of the display data displaying on said liquid crystal display section to low values responding to an external instruction.
