LED display gray scale identification level and brightness identification level test

LED display gray scale identification level and brightness identification level test   ALISEN specializes in commercial displays The grayscale level of ALISEN LED displays depends mainly on the number of A/D conversion bits of the system. Of course, the system's video processing chip, memory and transmission system should provide the appropriate number of bits to support. Currently ALISEN domestic LED display mainly uses 8-bit processing system, that is, 256 (28) levels of gray scale. Simple to understand is from black to white there are 256 kinds of brightness changes. Using RGB three primary colors can constitute 256 × 256 × 256 = 16777216 kinds of colors, that is, usually referred to as 16 trillion colors.ALISEN international brand display mainly uses 10-bit processing system, that is, 1024 levels of grayscale, RGB three primary colors can be composed of 1.07 billion colors.     Although the gray scale is the determining factor in deciding the number of colors, it is not that the larger the better without limit. Because the resolution of the human eye is limited, and then the increase in the number of bits of system processing will involve the system video processing, storage, transmission, scanning and other aspects of the change, the cost of a sharp increase in cost-effective rather than decline. Generally speaking, civil or commercial grade products can be used 8-bit system, broadcast grade products can be used 10-bit system. ALISEN Brightness identification level: The brightness discrimination level of ALISEN LED display refers to the brightness level between the blackest and whitest images that the human eye can distinguish. As mentioned earlier, some gray levels are very high and can reach 256 levels or even 1024 levels. However, due to the limited sensitivity of the human eye to brightness, and can not fully recognize these gray levels. That is to say, there may be many adjacent levels of grayscale human eyes look the same. Moreover, the eye's ability to recognize these levels varies from person to person. For LED display, the human eye to recognize the level is naturally the more the better, because the image displayed is, after all, for people to see. The more luminance levels the human eye can distinguish means the larger the color space of the display and the greater the potential to display rich colors. Brightness identification level can be tested with special software, the general display can reach more than 20 levels even if it is a better level.

Installation Steps and Precautions for Outdoor LED Display Screen

LED display screen is actually a new type of electronic device made of light emitting diodes arranged in a certain order, mainly used for "imaging", and its advantages are: high brightness, wide viewing angle, and long life. Therefore, most outdoor advertising screens are made of LED screens.   What is an outdoor LED display screen?   Outdoor LED display screens, as the name suggests, are LED displays installed and used outdoors. Outdoor LED display screens are the main carrier and means of outdoor display advertising at present and in the future. Currently, with the widespread application of outdoor LED screens, major customers have not only put forward requirements for beautiful appearance, but also have stricter requirements for installation quality and method. Below, I will share with friends the installation method of outdoor LED screens and the matters needing attention during the installation process. What are the installation steps for outdoor LED display screens?   The specific installation steps and procedures for installing outdoor LED display screens are as follows:   Step 1: Processing, manufacturing, and fixing the "home" of outdoor LED display screens.   Outdoor LED displays are not installed on the ground. Generally, outdoor LED displays should have a "home" at a high place. Currently, the "home" of outdoor LED displays is made of steel structures, which are the brackets on the back of the display screen. Due to the outdoor LED display screen will be fixed on the bracket for a long time after installation, so the bracket must be strong and firm.   Step 2: Install the outdoor LED display box.   The box of outdoor LED display screen is the main part, or the main body of outdoor LED display screen, which includes a sheet metal box, unit module, switching power supply, power cord, row cable, fixing screws, etc. In a word, after installing the LED display box, it can be said that the outdoor LED display is installed. Because, in general, the outdoor LED display screens we purchase are all manufactured and assembled in good condition, all on their boxes.   Step 3: Power on and debug the outdoor LED display screen.   After installing the outdoor LED display box properly, the rest is to turn on its power supply and start debugging. Only after the debugging is normal can the outdoor LED display installation be said to be smooth.   Step 4: Outdoor LED display screen decoration.   After installation and debugging, the outdoor LED display screen can be said to work normally, but in order to be beautiful, decoration is essential. After all, bare steel brackets and boxes are difficult to call beautiful.   After decoration, the outdoor LED display can be put into use. But what do you need to pay special attention to during the installation process?   What are the precautions during the installation of outdoor LED display screens?   1. Outdoor LED display screens should be equipped with necessary lightning protection devices. Outdoor LED display screens are installed outdoors, and thunderstorm weather is inevitable. In order to ensure their service life, lightning protection measures are very important.   Outdoor LED display screens must have necessary waterproof devices, or LED display screens must undergo special treatment and have waterproof performance. Rainwater is a common hazard during the use of outdoor LED displays. In order to ensure their normal use and service life, waterproof issues must be addressed. Therefore, during the installation process, supporting ventilation and moisture prevention devices and reserved drainage holes should be provided to prevent water from being unable to drain.   3. Outdoor LED display screens should use high brightness light emitting diodes. Because outdoor LED screens are mainly used for business promotion, most are installed in places with broad views and no obstructions, and are exposed to direct sunlight. In order to ensure that LED screens can still maintain remote visibility under strong light irradiation, using high brightness light emitting diodes is a necessary option.   In general, when installing outdoor LED display screens, attention should be paid to waterproof, ventilation, and moisture prevention, as well as lightning protection. Outdoor highlight modules should be selected, and the brackets and frames for fixing the display screen should be firm to prevent the screen from falling off due to bad weather.

These displays offer a superior viewing experience, with bright, crisp images and vibrant colors. But with so many options on the market, how do you choose the right one for your studio? Here are some key factors to consider when sourcing a fine pitch LED display:   Pixel Pitch Pixel pitch refers to the distance between each LED on the display. The smaller the pixel pitch, the higher the resolution and image clarity. For a studio setting, a pixel pitch of 1.5mm to 2.5mm is recommended for optimal image quality.   Brightness Brightness is another important consideration for studio LED displays. You'll want to choose a display with a brightness level of at least 800-1000 nits to ensure that your content is visible in all lighting conditions.   Contrast Ratio Contrast ratio refers to the difference between the darkest and brightest parts of an image. A higher contrast ratio means better image quality and more vibrant colors. Look for a display with a contrast ratio of at least 3000:1.   Viewing Angle In a studio environment, it's important that your LED display has a wide viewing angle so that everyone in the room can see the content clearly. Look for a display with a viewing angle of at least 160 degrees.   Serviceability Finally, you'll want to consider how easy it is to service and maintain your LED display. Look for displays that are designed for easy front or rear access, with modular components that can be easily replaced if necessary.   By keeping these factors in mind when sourcing a fine pitch LED display for your studio, you can ensure that you're getting a high-quality, reliable display that will meet your needs for years to come.
