Experts, what kind of camera do you need to use to shoot large outdoor ads, so that pixels can support it?
It depends on how large it is. If it's big enough, you can only use large frames. The general 135 is definitely not good. Nikon's D3x is higher, but it's not good if it's enlarged.

1. Strictly speaking, bitmap can not be converted into vector (that is to say, the software still supports conversion, but the distortion is very serious). Because the calculation method of vector graph is coordinates rather than pixels, the vector can be enlarged or reduced arbitrarily without distortion, that is to say, the vector can be converted into bit map, and the same size will not be distorted after being converted into bitmap

The basic unit of LED display is the light-emitting tube. The principle of the light-emitting tube is to package a group of three primary color (red, green, blue) light-emitting diodes in a plastic tube, and enhance the brightness through common light-emitting. Display screen is divided into graphic display screen and video display screen, which are composed of LED matrix block.

Hello, yes. It's brighter in 4-scan than in 8-scan. If the driving circuit lights up all the pixels on the screen each time, it is called static driving. If the rows or columns lit up each time are discontinuous, for example, there are 1,2,3,4,5,6,7,8,9,10... Rows of pixels, one and nine rows are lit up at one time, then in a very short time, 1 and 9 are off, 2 and 10 are on, and then in a very short time, 3 and 11 are on, that is 1 / 8 scan; If 1 and 5 are on, it will be replaced by 2 and 6 lines in a short time. Recursion is 1 / 4 scan; Because people have the characteristics of visual persistence, they can't see that the light has been off, and they still look like a/

Generally speaking, the row and column control mode is used in the general control method of indoor screen, which is commonly known as the scanning mode. At present, the driving mode of LED electronic display has two kinds: static scanning and dynamic scanning. The static scanning is divided into static real pixel and static virtual, and the dynamic scanning is also divided into dynamic real image and dynamic virtual. For example, buroke LED electronic display is divided into indoor full-color LED electronic display scanning mode: P4 and P5 are constant current 1 / 16, P6 and p7.62 are constant current 1 / 8; The scanning mode of outdoor full-color LED electronic display: P10 and p12 are constant current 1 / 2 and 1 / 4, p16, P20 and P25 are static; Single and double color LED electronic display screen/

How big is the area of the LED advertising electronic screen hanging on the outdoor wall? Which specification and model should we use
If the outdoor advertising screen is in the business circle and the viewing distance is relatively close, P8 and above models can be considered, so that there will not be a strong sense of particles in the case of close viewing. As for the area, it depends on the installation environment and cost budget. You can talk about your needs before you choose the LED screen engineer, ask him to give you a recommendation and quotation, and then find several peers to make a comparison, see the strength, and then make a decision.

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD splicing screen? That is, if the mosaic screen image is magnified several times, there will be a lot of small square points, these lower points are actually the so-called pixels. The following Shenzhen LCD panel manufacturers Prudential display technology to take you in-depth understanding of what is the LCD panel pixel splicing.
