Utilizing a patented technique, B-Module employs multi-chip LED sources and specialized refractive optics to generate a dynamic dappled lighting effect. In this issue, we will present two papers on backlight technology, one describing the general direction of backlight units (BLUs) and the second showing state-of-the-art design considerations for a compact optical structure with local dimming. There are two basic BLU concepts: (a) a cavity. The special feature of the B. This effect varies in light and dark intensities, adaptable to specific applications, while offering an eco-sensitive spectral range inspired. Most of the lights in the MQB car with “complex” logic are controlled by the BCM module (09 – Central Electronics in the network, J519 in current flow diagrams). They all start with Leuchte. names in the adaptations (“Lamp” in German). A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides light from the back or side of a display panel. Backlights. Backlight Module, the light source of TFT-LCD, is constructed by optical films, light guide plate, LED light bar, back-cover and plastic case. Because the liquid crystal molecule only function as the penetration level that doesn't illuminate spontaneously, it is necessary to add a backlight module.
