theae also uses dynamic lighting design, and optimized to better highlight the features of the facade of historical results. morgan patel that the urban lighting planning stage lighting design is more than challenging. design of the stage lighting, the designer is like a sculptor, they are free to create any want viewers to see the scene, and can conol their own preferences ultimate lighting effects. the lighting is very difficult to conol the city, as seet lamps, indoor lighting the buildings, the moon, the sun will be the end of the city have a huge impact lighting effects, it is more complex. morgan ritter to "side of the road in a noisy sing quartet playing" to the people to make a vivid metaphor. cities need to consider more environmental art background, but it is still in his pursuit of art part of it.

writing boardled backlight technology advantages of the two: light elegant led backlight is the number of grid-like semiconductors, each "grid" has an led in both the semiconductor, so that you can successfully planar source. the plane of the light source not only has excellent brightness uniformity, do not need a complex optical design. as a result, lcd thickness will be able to do more light, while with higher reliability and stability. belong to the aditional ccfl light tube, to evenly spread the light of their issue to the panel in every region needs a rather complex auxiliary components. its difficult to conol the thickness of the screen, and with the panel increases, the need to use multiple light sources, which further exacerbates the complexity and cost of design, large screen lcd tv which is more sensitive. for example, 50 inches above the lcd or tv product.
