We often hear that the grayscale of the LED display is what is the brightness and brightness, so how much do you know about the grayscale and brightness of the LED display? Let's take a look at the explanation given by itc professionals. Led display grayscale, also known as color scale or grayscale, refers to the brightness of the degree of brightness. For digital display technology, grayscale is the determinant of the number of colors displayed. In general, the higher the grayscale, the richer the color displayed on the display screen, the more delicate the picture, and the easier it is to express rich details. The gray level of the LED display mainly depends on the number of A/D conversion bits of the system. Of course, the system's video processing chip, memory and transmission system must provide the corresponding bit of support. At present, the domestic LED display mainly adopts an 8-bit processing system, that is, 256 (28) level grayscale. The simple understanding is that there are 256 brightness variations from black…

The use environment requirements for an LED display utilized in outdoor advertising are substantially greater than for typical displays. Due to the varied environment, outdoor LED displays are frequently affected by high temperatures, typhoons, rainstorms, lightning, and other poor weather. What precautions can we take to keep the display safe in bad weather?   First, high-temperature resistance Outdoor LED displays are generally larger, and as a result of the higher power consumption, the corresponding heat dissipation is also higher. When combined with the higher external temperature, if the heat dissipation problem is not addressed quickly, it is very likely to cause circuit board heating short circuit and other issues. Ensure that the display board is in good working order, and when building the housing, choose for a hollow design that promotes heat dissipation. When installing, ensure that the display has good air permeability and, if necessary, improve the heat dissipation equipment for the display, such as adding air conditioning or fans inside, to help the display cool. Second, typhoon prevention The location of an outdoor LED display is various, as is the installation method; there are wall types, mosaic types, column types, hanging types, and so on. Then, during typhoon season, tight criteria for the load-bearing steel frame structure of the outdoor LED display are put in place to prevent the screen body from sliding off. The engineering unit must be built and placed in strict accordance with anti typhoon level criteria, while also having a seismic ability to ensure that the outside LED display does not fall off, causing injuries. Third, prevent heavy rain In the south, there are many rainy days, thus the LED display must have a high level of waterproof protection to avoid being eroded by moisture. In an outside application, the outdoor LED display should have an IP65 rating, the module should be sealed, a waterproof box should be used, and the module and box should be connected with a waterproof ring.   Fourth, lightning protection Direct lightning protection: If the outdoor LED large screen is not within the direct lightning protection range of nearby high-rise buildings, a lightning rod should be set on…

The biggest function of an LED video processor is to convert an image signal from an external source into a signal acceptable to the LED screen. How does an LED video processor complete the perfect display of the LED screen? 1) Signal conversion and switching, video processing equipment can complete the format conversion between many signals. Another important function of the video processor is to manage a variety of signals when multiple signals are connected, having  the flexibility to switch between them quickly. 2) Screen zoom, the full-color display is point-to-point, which determines that the full-color LED screen can only display the same size as its own physical resolution of the picture. The LED video processor can scale the image, output the picture at any size, and map the entire desktop to the LED screen. 3) Image quality is improved because the pixel…

With the continuous improvement of LED display design technology, users have higher and higher requirements for LED display quality. Designing, producing and using high-quality LED display is the common wish of manufacturers and users! Its conversion frame rate determines the stability of LED display screen. What is the frame rate of LED display screen? Let's take a look at the frame rate change of LED display. The LED display is driven by the current flowing through. If the design of the system end is not considered, the refresh frequency is determined by the addressing time and the current speed flowing through the LED. The calculation formula of refresh rate is: X frame rate of horizontal synchronous scanning line = refresh rate. Generally, the refresh rate of flat panel display is set to be more than 75, otherwise, it will feel some "flash". In short, it is the number of times the display screen is repeatedly displayed by LED display screen; LED display frame rate: in addition to system support, the improvement of LED display frame rate needs to speed up the addressing speed, and there is a strong correlation between addressing time and transmission frequency (DCLK). The number of frames: that is, the frames used to display continuous…

When buying LED displays, the precautions for choosing fine pitch LED displays: users should consider their own cost, demand, the scope of application and other factors. Before buying a fine pitch LED display, decide whether you really need a small spacing. It should be decided according to the actual situation. The prerequisite is "low bright high gray". As a fine pitch LED screen of the display terminal, we must first ensure the viewing comfort, so when purchasing, the primary consideration is the brightness. Relevant studies have shown that, as an active source, the brightness of LED is twice that of passive luminescence (projector and LCD) in terms of human eye sensitivity. In order to make the eyes look more comfortable, the brightness range of fine pitch LED screen can only be between 100cd / m2 and 300cd / m2. When selecting point spacing, we should pay attention to the balance of "effect and skill" Ordinary LED screens want to get good visual effects. Some people can only see the sight distance and fine pitch LED screens. Users can simply measure P2 through sight distance = sight distance / 0.3 ~ 0.8. For example, the viewing distance of P2 fine pitch LED screen is about 6m. Select the resolution and pay attention to the matching with the "front-end signal transmitter". The smaller the dot spacing of the low spacing LED screen, the higher the resolution, and the higher the definition of the image. In practice, users want to construct a good LED display system with small spacing. While paying attention to the…

The LED screen has the advantages of energy-saving, environmental protection and long life, and has broad development prospects. However, temperature is very important for LED screens. The temperature has a great impact on LED screens: it is related to the service life, light efficiency, and color of LED screens. Therefore, the correct temperature is very important for the large LED screen. 1、 For LED screen, the influence of temperature is as follows: The high temperatures will cause complete damage to the working temperature of the large LED screen. Exceeding the load temperature of the chip will lead to a sharp decline in the luminous efficiency of the LED screen, resulting in obvious light attenuation and damage; Most LED screens are encapsulated with transparent epoxy resin. If the junction temperature exceeds the solid transition temperature (usually 125 ℃), the packaging material…
