In the period of rapid development in the 21st century, LED displays have also developed rapidly. Nowadays, small-pitch LED displays have become suitable star products, and their market applications are also very wide. Extensive. However, after various manufacturers have carried out marketing plans, for many industry users, small-pitch LED displays may not be new, but how to choose the products they need?
For small-pitch LED displays, the smaller the dot pitch, the higher the resolution, and the clearer the display effect; in the small-pitch LED display market , Manufacturers are concentrated here. However, in actual operation, users in the industry hope to build the best small-pitch LED display system. While paying attention to the screen resolution, they must also consider combining it with Combination of back-end signal transmission products.
Because there are multiple formats of video signals on the market, LED narrow-pitch screens are not compatible. Therefore, when users buy small-pitch LED boxes or modules, they must choose according to their needs, consciously catch up with the trend, and prevent waste of resources.
Element 2: When choosing the dot pitch of the LED display, pay attention to the effects and techniques of white balance.
Compared with the previous LED display, the small-pitch LED display shows the most significant feature of small dot spacing. Practical applications show that the smaller the display pitch, the greater the pixel density, the greater the amount of information displayed per unit area last time, and the closer the appropriate viewing interval . On the contrary, the interval suitable for observation becomes longer. Therefore, considering the popularity of the concept of small-pitch LED displays, many users in the industry naturally think that when buying display products, the smaller the spacing, the better , But this is not the case.
In order to obtain the best visual effect, the LED display has the best viewing distance, and the small-pitch LED display is no exception. Industry users want to stop simple measurement. The default formula is: best display interval = dot spacing/0.3~0.8. The cost of the small-pitch LED display should be known. The smaller the dot pitch, the higher the cost of the small-pitch LED display. Therefore, in actual selection, the user must Comprehensive consideration of cost, demand, application scope and other factors.
Element three: select the display brightness, "low brightness and high gray" is a prerequisite.
In order to ensure that people can see the warmth, the first thing users should consider when buying small-pitch LED display products is brightness. The brightness of LEDs is 2 times higher than that of passive light-emitting sources (projectors and liquid crystal displays), but in order to make people visible and warm, the brightness range of narrow-pitch displays is only 100cd/m2-300cd/ m2, however, in the existing LED display technology, reducing the brightness of the screen will cause grayscale loss, and grayscale loss will directly affect the image quality.
Therefore, an important criterion for high-quality small-pitch LED displays is to achieve the technical indicators of "low brightness and high grayscale". After actually selecting the option, the user can follow a benchmark, that is, "the more brightness levels that the human eye can recognize, the better." The brightness level is the brightness level of the image from the darkest to the whitest that can be recognized by the human eye. The more recognized, the greater the color space of the display, and the more likely the color is. Big
