The disadvantage of DLP is that it is prone to rainbow effect and the disadvantage of LCD projector is that the contrast ratio is average.
DLP and LCD Projector which is better?The disadvantage of DLP projectors is that they are prone to the rainbow effect, The disadvantage of monolithic LCD projectors is the average contrast ratio.
The biggest advantage of LCD projector is that the three primary colors of red, green and blue are done by 3 separated LCD plates, which can control the brightness and contrast of each color individually, and the three colors of light can reach the screen almost at the same time, so it can truly reproduce various colors.
The color separation of a single DLP projector is achieved by a color separation wheel, and the three colors of light are reflected using the same micro-mirror modulation, so the three colors of light arrive at the screen at different times, and due to the limitations of the color separation wheel speed and micro-mirror deflection speed, there is a certain gap in color reproduction compared to LCD projectors. Especially when displaying dynamic video images, LCD technology will have an advantage over DLP technology due to the faster image refresh rate and the higher modulation speed required for each color.
Because most DLP projectors use a monolithic structure with simple optics, they can achieve a smaller size and lighter weight. Because of the reflective principle, DLP projectors can achieve a higher black and white contrast ratio.LCD consists of three colors of light converging into one pixel point, while single-chip DLP projectors have all three colors of light reflected from the same micro-mirror to the same pixel point, so there is no convergence problem, so the edges of the pixel point do not have some shadows as in LCD, so when displaying some fine lines and small font size text, DLP projectors The DLP projector will be sharper than the LCD projector, with purer blacks and whites and richer grayscale levels.
