    摘要： An image display device and method therefor, which improve a visual contrast feeling by regulating a contrast and light source with a correlation maintained therebetween. A feature detection unit (11) detects MAX, MIN and APL of an input image signal. A control data generating unit (12) determines Gain for amplifying the difference between the MAX and the MIN up to a dynamic range width, and Offset for affording a DC level shift amount at which the input image signal to be amplified by the Gain falls within the output dynamic range of a DC level regulating unit (13B). A signal amplitude regulating unit (13A) amplifies the input image signal based on the APL and according to the Gain. The DC level regulating unit (13B) level-shifts the amplified input image signal according to the Offset value. The light source control unit (16) controls a light source (18) based on the Offset so that a visual brightness level on the screen is identical with a brightness level of the input image signal.

    摘要： A display (1) for displaying an image and a method for driving such display is proposed. Therein, the display comprises: a background light (31), a first LCD panel (3) defining an array of pixel elements (13), a second LCD panel (5) defining an arrayofpixel elements (29) and a control unit(37) for driving the first and second LCD panels (3, 5). The second LCD panel (5) is a color display and is arranged between the first LCD panel (3) and the background light (31). The control unit (37) is adapted to controlthe second LCD panel (5) such that a white color point of the display (1) may be adjusted. Preferably, a diffuser (33) is arranged between the first display (3) and the second display (5). Accordingly, on the one hand, such display shows enhanced displaying properties such as an increased contrast and viewing angle, while, on the other hand, the white color point of the display can be adjusted as desired by using the controlunit(37) for correspondingly controlling the second LCD panel (5) being preferably a low resolution color display.
