Reference 2. What is DLP?

Comparison LCD with DLP

Image Quality

Pixelization

(fill factor)

DLP= ‘Seamless’, Filmlike
LCD Grainy Pixellated

LCD= Grainy, Pixellated

DLP™ = large ‘active’ area

LCD = smaller ‘active’ area

Contrast Ratio

DLP= simple optics: easier light management
LCD= complex optics: more difficult light management

Sharpness

(color alignment)

DLP= no misalignment

LCD= misalignment likely over time

Video Quality

DLP™

LCD

Video Quality

DLP= fast switching: minimal ‘lag’ (few

LCD= slow switching: significant ‘lag’ (tens of ms)

smearing for fast moving video
