"Do you know if the blurring can be corrected?" The refresh rate needs to be increased. To do that means formulating new LC materials and/or tweaking various parameters. "Is the backlighting connected to the blurring?" No. "How is plasma lit?" The plasma, which is a gas where the electrons have been stripped from the atoms, gives off UV which excites colored phosphors. So they glow. This is also the weak spot, over time the UV causes the phospors to degrade. So a plasma screen loses brightness over time. The problem with the backlights on LCD TVs is that because the LCD basically filters the backlight, they can't be as bright, nor have as good of a contrast ratio. So they are more sensitive to ambient light.
