Abstract
A multimedia displayer comprises a display panel (1) and a direct-type backlight source (3). When the multimedia displayer displays a frame via the display panel, luminous components, positioned within a specific range around the frame, in the direct-type backlight source are controlled to be non-luminous or lower in luminance, or luminous components relatively close to the periphery of the frame within the range are controlled to be non-luminous while other luminous components are lower in luminance, so that the frame is in the LOMO (Leningrad optical mechanical association) style. The multimedia displayer has the advantages that the frame is enabled to be in the LOMO style by means of controlling luminous modes of the luminous components in the direct-type backlight source, and thereby the problem of distortion or freeze in frame display is avoided due to the fact that burden of an internal image processing circuit cannot be increased additionally; moreover, power consumption of the backlight source can be reduced when the frame in the LOMO style is displayed.
