Advertising screen displays are a great way to promote the latest product line or custom service to a broad target market. These outdoor LED displays can be very large so passersby on the highway or major intersections can read them quickly and clearly from great distances. Because LED technology is relatively efficient and can be found in thin form factors, the wide range of applications has led to many common problems such as overheating, cracking, failure or outright permanent damage. This is why you must take precautions to ensure the longevity of different advertising screen displays. Reasons to maintain the display of the ad screen You want to maintain your LED advertising screen display because you are using it to increase online and in-person traffic to your business. For example, consider displays at major intersections such as Times Square in New York City, USA. These ads promote everything from upcoming Broadway shows to famous brands to watch from afar. Since a lot of commercials and user-generated content are created around these giant screens, you need them to run at their most efficient capacity at all times. Unfortunately, it also reduces operating costs because you don't have to spend resources on improving, repairing, or replacing such a large advertising wall display. Influencing factors of monitor life Here are a few things you need to keep in mind to improve the lifespan of your recently acquired ad display ads, including: 1. Heating High temperatures or extreme temperatures can warp or damage your LED screen display without proper consideration. This will help to double check that the LED display supplier you are using has excellent cooling components installed in the product. 2. Weather If any water gets inside the sealed LED screen, it will damage the screen and possibly replace the entire advertising screen display.

LED grayscale can also be called LED brightness. The gray level is also called half-tone (Half-tone), which is mainly used to transmit pictures, and it is 16.32.64. It uses matrix processing to process file pixels to 16.32.64 level, making the transmitted picture clearer. Whether it is a single-color, two-color or three-color screen, images or animations need to adjust the grayscale of each LED that makes up a pixel, and the accuracy of the adjustment is often referred to as grayscale. There are two ways to control the LED grayscale: one is to change the flowing current, and the other is to adjust the pulse width. 1. Change the current flowing through the LED. Generally speaking, the continuous working current of the LED tube is about 20 mA. Except for the red LED saturation, the other LED grayscales are basically proportional to the flowing current; 2. Use the visual inertia of the human eye and pulse width adjustment to achieve grayscale control, that is, the periodic change of the light pulse width (ie, the empty ratio). As long as the repeated illumination period is short enough (that is, the refresh rate is high enough), the human eye will not perceive the shaking of the light-emitting pixels. Since pulse width adjustment is more suitable for digital control, almost all LED screens use pulse width adjustment to control gray levels. LED control system usually consists of main control box, scanning board and display device.

led tv Strictly speaking, LED TV refers to a TV that completely uses LED (light emitting diode) as the display device, and is generally used for low-precision displays or outdoor large screens. At present, the strict name of the LED TV commonly referred to in the home appliance industry in mainland China is "LED backlight LCD TV", which refers to the LCD TV with LED as the backlight source, which is still a type of LCD. The difference between led TV and LCD TV First, the nature of LED TV. When many people hear about LED TV, they think it is a newly developed brand new TV. In fact, this is wrong. LED TV is also a kind of LCD TV. Its real name is LED. Backlight LCD TV, it only replaces the CCFL backlight technology of ordinary LCD TVs with LED backlights. Therefore, LED TVs are only a certain upgrade on ordinary LCD TVs. The essence is still a kind of LCD TV. Second, the difference in appearance LED TVs are generally much lighter and thinner than ordinary LCD TVs, as thin as 29.9mm, or even thinner, so it is very convenient whether it is placed on the TV cabinet or hung on the wall. Third, the difference between colors. People who have carefully compared the colors will find that the colors of LED TVs are more realistic than ordinary LCD TVs, especially for high-definition movies. This is because the color gamut of LED TVs can reach 105, while ordinary LCD TVs. TV is far from it. Fourth, the service life LED TV has a very big advantage in this regard. According to statistics, a general LED TV can support about 100,000 hours, that is to say, if you watch 8 hours a day, you can use it for 34 years; while ordinary LCD TVs It is easy to age, and the use time is much less.
