LED display with small spacing DLP, LCD, etc. The difference between the traditional screen

1. Flat-fell seam. LCD and PDP has flat-fell seam problem, DLP slightly better, projection fusion when handled well able to rid of stitching area; Small spacing no flat-fell seam LED display technology.

2. According to the effect. From the gray level and contrast, brightness and refresh rate index, DLP rear projection and projection and the effect of fusion technology shows the worst ( By the projection of the physical attribute determines the worst) , LCD display effect is good, but after using for a long time, because of the brightness attenuation and appear dark side, black Angle, also can appear between the screen and screen brightness and color difference, and the human eye is sensitive to different things.

3. Resolution. DLP, LCD has higher resolution, 60 inches single hd display unit resolution can reach 2 k, and the small distance between the LED display technology due to the pixel is made up of lights, so on the premise of cost control, the resolution is lower than other techniques. Such as display and the resolution of the signal source matching problem, used for advertising in areas such as outdoor LED display don't need to have standard resolution, customer only care about display effect and brightness. Small spacing between the LED display after entering indoor application, the downstream applications rapidly expand, such as command, control, monitoring and other fields, often need to display to match the output of each subsystem is standard resolution signal, for example 1920 x 1080 signal of high-definition cameras, etc. And within the prescribed size, standard LED display cabinet resolution may not be able to piece together the required standards.

4. Cost problem. In all indoor large screen display solutions, and the lowest cost is LCD splicing and projection and fusion ( Because the cheapest LCD splicing in the field of indoor display wall accounted for the largest share of the) , followed by the PDP splicing. Compared to the small distance between the LED display and DLP rear projection splicing, hardly what does tall what is low, because of the differences between interval specifications of the LED display, small spacing cost difference is bigger, the P1. 9 display and sale price per SQM DLP rear projection splicing quite, but the account of the differences of gross margin, even higher than DLP Mosaic products. For material benefit is the highest of industry users, on the premise of meet the application requirements, consider cost-effective integrated, small spacing leds may not be preferred. Has always been the high cost is the main problem with small spacing LED, although small spacing LED has many advantages. But as the market continuously, small spacing LED technology of rapid ascension, technology cost is greatly reduced. The current P1. 2 of the following product commercial cost is too high, users still can't afford. This also means that, before the current LED the innovation of technology without big, small spacing, cannot be popularized.

5. The service life. From the point of use time length, pure LED display technology has the longest service life, because indoor applications, the LED display brightness demand is very low, 20% maximum output power can meet the requirements.
