Theoretically speaking, the biggest advantage of LCD projector is that the three primary colors of red, green and blue are completed by three separate LCD panels, which can control the brightness and contrast of each color separately, and the three colors can reach the screen almost at the same time, so it can reproduce all kinds of colors. The color separation of single-chip DLP projector is realized by a color separation wheel. The three color light is modulated and reflected by the same micro mirror, so the three color light reaches the screen in time.

What is the difference between DLP and LCD projectors?

the color separation of single DLP projector is realized by a color separation wheel.
the three color light is modulated and reflected by the same micromirror, so the three color light reaches the screen in time sharing. Due to the limitation of the rotation speed of the color separation wheel and the deflection speed of the micromirror, the three color light reaches the screen in time sharing, There is a certain gap in color reproduction compared with LCD projectors.
especially when dynamic video images are displayed.
because the image refresh speed is relatively fast and the modulation speed of each color is relatively high, LCD technology will have more advantages than DLP technology.
.
.
because most DLP projectors use single-chip structure.
the optical structure is simple, So it can achieve smaller volume and lighter weight.
because of the reflective principle.
DLP projector can achieve higher black-and-white contrast.
LCD is converged into a pixel by three color light.
while single DLP projector is reflected to the same pixel by the same micro mirror, so there is no converging problem, The edges of pixels will not appear any burr or shadow in LCD, so when displaying some thin lines and small text, DLP projector is clearer than LCD projector, black and white are purer, and gray level is richer.
.
.
in addition.
because every pixel of LCD projector has a transistor called light switch, The transistor can't transmit light, and there must be a certain gap between the pixels due to the existence of the transistor.
however, the DLP projector has a control transistor on the back of the micro mirror.
the DLP projector has a control transistor on the back of the micro mirrorThe gap between the micro mirrors can be very small.
therefore.
the gap between the pixels in the image projected by the LCD projector is larger than that of the DLP projector, Especially for low resolution products.
.
now the mainstream is LCD and DLP. Led, many technologies are immature and seldom used.
brightness is too low.
simply speaking, the price of LCD and DLP is difficult to compare.
LCD is an imported DMD chip. With the development of LCD, the price will be reduced.
of course, manufacturers will constantly introduce new models.
there is no comparability between the two in terms of price, Because things are not the same. LCD panels are bad, and DLP chips are high and low. From the point of view of the same lumen machine, LCD is higher than DLP.
DLP light path is dust-proof.
high contrast, strong sense of hierarchy, and rigid colors. It is suitable for engineering drawings.
LCD panels will turn yellow when used for a long time.
to clean, bright colors. It is suitable for graphic design
