- - - - TN vs IPS P.686
        
        Twisted Nematic (TN) use thin film transistor (TFT) (active matrix technology ) to display
        
        6 bits display - red, green, and blue
        
        18 bit display will not reproduce the full 24-bit true color
        
        Disadv
        
        Panel fudges a little bit when asked to do something it can't do
        
        This can produce noticeable problems with reproduction
        
        In-Plane Switching (IPS) P.689
        
        Create a wider viewing angle and far better color re-creation than TN panels can provide
        
        Used for graphic professionals
        
        Manufactures use many types of IPS technology to find the right mix of price-to-performance.
      - Fluorescent vs. LED backlighting P.689-690
        
        LCD Monitors with CCFL backlights
        
        Cold cathode fluorescent lam(CCFL)
        
        Low power use
        
        Brightness
        
        Long life
        
        Use AC power, but given the transformer converts the
        AC power--> DC power
        
        LED Monitor
        
        Light-emitting diode (LED)
        
        Disadv --> costs a lot more than the edge types
        
        The edge type function similarly to a CCFL-style display
        
        Reduces the overall electricity usage
        
        (X) use AC power
        
        outstanding contrast and color
        
        Reduces the thickness of the panel
        Used for many smaller devices such as smartphones and tablets
    - - Lights the screen with an organic of compound
      - Use less electricity than LCSs
      - Screens larger than half a dozen iches
      - Disadv
        
        Too expensive to make for mainstream consumer devices
        
        Don't use backlights at all - can display true black
