Did LCD splicing screen and dlp rear projection difference
DID LCD display system consists of three major components, namely, splicing display wall, multi-screen splicing processor and signal source. Among them, multi-screen splicing processor is the core of the key technology, while supporting different pixel images on the large display wall display as well as in the large display wall arbitrary open window, window zoom in and out, cross-screen roaming display. But dlp large screen splicing system is the cold light source emitted through the UHP bulb through the condensing lens, through Rod will be light uniformity, after processing the light through a color wheel (ColorWheel), the light will be divided into RGB three colors (or RGBW and other more colors), and then the color by the lens projected on the DMD chip, and finally reflected through the projection lens on the projection screen imaging.
And DLP digital light processing technology: its imaging principle is based on chip-level full digital processing and the full use of light efficiency of the reflective imaging structure. In terms of resolution, contrast and other core index parameters, it has relative advantages over other display application technologies. Relatively more suitable for the application of industrial control image screen mainly for displaying fine graphics. Its professional box splicing process, the splicing gap can reach the level of less than 0.5mm, fully reflecting the scale advantage of the large screen (LSD) display mode, and the overall structure of the system is solid and stable.
But DID LCD splicing due to thin and light equipment, easy to install, suitable for small-scale decentralized display applications (generally more commercial applications), the main imaging principle in the presence of backlight plate, compared to plasma products, its display brightness is better. To say that the biggest difference between the two products is the visual above: DLP splicing way splicing only 0.5mm, the visual effect is better; and DID LCD splicing the current technology the smallest splicing 7.3mm, the splicing gives a greater intuitive impact, especially in terms of text.
Did LCD splicing screen and dlp rear projection with which good
A, the budget less with Did LCD splicing screen, high budget with dlp
Due to the different technical composition, Did LCD splicing screen and dlp in the overall price or a big difference, from the industry average price, the price of a Did LCD splicing screen according to the size and spacing is different probably in a few thousand dollars, while the smallest size of the dlp 60 inch screen price of about 30,000 yuan a piece, the price difference of several times. And in the after-sales costs, Did LCD splicing screen basically no, because its stability is better, rarely out of order, while dlp need to replace accessories regularly, the follow-up expenses are higher.
Therefore, we can design the size and area according to their needs first, so as to project the need for several screen splicing, so that you can calculate the overall cost, you can decide which one to use according to their affordability.
Second, want a small splicing with dlp
Whether it is Did LCD splicing screen or dlp, two have a certain spacing, but the dlp spacing is relatively small, the current minimum spacing Did LCD splicing screen for bilateral 0.88mm, while the dlp spacing is only one, about 0.2mm, resulting in the overall difference is the dlp splicing display effect is better, the screen and screen display barriers between smaller, the image does not have a sense of split.
Third, according to the installation environment selection
The installation environment is different, the products used are different, such as dlp brightness is lower, larger, so in some installation space is not much and good lighting occasions can not use dlp, because the brightness is low in the better light when the screen will reflect, resulting in not seeing the above content clearly, in addition dlp screen depth will reach about 50cm, and only after maintenance installation, very occupy space.
And Did LCD splicing screen support before maintenance, and its panel is only about 5 cm, easy to install, more space-saving. In addition is the LCD brightness is higher, even if the lighting is better or installed in the hall can also reach the normal viewing requirements, the screen will not reflect and so on.
Fourth, the future development trend
In recent years, with high cost, high stability and a series of advantages, did LCD splicing screen ushered in rapid development, almost every year the growth rate can reach more than 30%, in addition to the traditional security monitoring display field, but also to the meeting, display, advertising and other areas of expansion. And dlp due to its cost performance is not high, maintenance costs are also high, and with 0.88mm ultra-narrow LCD panel on the market, its spacing advantage is no longer obvious, so nearly to the use of the years less and less, the overall trend of decline.
So, in choosing whether to use did LCD splicing screen or dlp, must be considered from many aspects, both also have their own advantages and characteristics, but from the overall application and development, LCD is undoubtedly a better choice.
