Abstract:
1. A liquid crystal backlight apparatus, comprising: a backlight configured to illuminate a liquid crystal display panel, the backlight having a plurality of light emitting diodes arranged in a matrix of rows and columns as a light source; a control part configured to use white light emitting diodes as the plural light emitting diodes and control luminance of the white light emitting diodes separately; and a plurality of control circuits configured to receive information for controlling a luminance of the light emitting diodes, with each control circuit configured to control a corresponding light emitting diode, wherein the information is generated by image signals supplied from an image signal process circuit to the liquid crystal backlight apparatus, wherein the image signals are serially supplied to the light emitting diodes arranged in the matrix of rows and columns from a top row to a bottom row starting with a light emitting diode at a position of a first row and a first column, and wherein the light emitting diodes are lit after the image signals are supplied.
