摘要： A backlight unit shortens the necessary time from the time immediately after the turn on to the time the emitted light is converged to a predetermined chromaticity while the quality of time-varying images is improved. Under the control of the backlight controller section, the Light-Emitting Diodes (LEDs), which are assigned to the respective light-emitting regions of the light-emitting surface, are driven to emit lights sequentially in the predetermined scanning light-emitting periods for the scan type lighting and the additional light-emitting periods in a single frame, responsive to the write scanning of an image signal to the LCD panel. The additional light-emitting periods are outside a corresponding one of the scanning light-emitting periods. In each additional light-emitting period, the LEDs emit light in synchronization with the supply of the optical leakage preventing signal (e.g., the black inserting signal) to the LCD panel.

摘要： An illumination system that makes it possible to generate light with less color irregularity with a simple structure while restraining the increase of size is provided. A tube-shaped reflector having a tube-shaped wall whose inner surface is reflective is provided. The wall includes an aperture extending along a longitudinal axis of the reflector. In the reflector, plural sets of LEDs are arranged, where colors of light to be emitted from the LEDs in each set are different (for example, red, green, or blue LEDs are used for each set). The LEDs in each set are arranged along the longitudinal axis of the reflector to form a linear light source. A collecting lens is fixed to the reflector in such a way as to fill the aperture of the reflector.
