EditWhat does "MLA" stand for?
MLA stands for Micro Lens Array. For LCD projectors MLA is an array of tiny lenses that coat the LCD panels inside the projector and improve the quality of the projected image.
EditWhat does MLA do?
LCD Projectors without MLA:
On an LCD projector without MLA you may be able to see the fine black lines running horizontally and vertically across the projected image in a grid pattern. This is described as similar to looking through a flyscreen door; the 'screen door effect'. The screen door effect is more noticeable on large screens and where the viewer is close to the screen.
LCD projectors with MLA:
On a projector with MLA these fine black lines are minimised to reduce the screen door effect and create a smoother projected image.
