At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which

LCD mainly consists of LCD black-and-white screen and TFT color screen. The following mainly introduces the relationship between the manufacturing difficulty and size of LCD black-and-white screen: According to expert statistics, the size and process difficulty of LCD segment code screen have such a rule: the larger the size, the more complex the manufacturing process. The main reasons are as follows:   The larger the size of LCD, the more difficult it is for staff to operate.   The larger the size of LCD is, the higher the requirement of equipment grade is.   The larger the size of LCD, the higher the defect rate of the product.   The larger the size of LCD, the more bad things will appear, such as darkening.

Compared with traditional advertising machines, what are the advantages of LCD advertising machines? The following editor will leave a brief introduction: The LCD advertising machine is very convenient to maintain the advertising content. The traditional advertising machine needs to copy the content with a computer first, and then a dedicated person will go to the advertising machine outlet to replace the CF card, which causes a waste of human resources and is very inefficient; the electronic online advertising machine is accessed through the Internet IP and passed in the office. Control the host, directly download the content to be updated to the advertising machine, and can delete, sort, set playback rules, interstitial control, aerial control, etc., all can be completed in a few minutes, and save a lot of labor costs. The advertising playback management of the LCD advertising machine has become more flexible and faster. Traditional LCD advertising players need to pre-arrange the program playlists. How to broadcast at the outlets usually takes a long time to implement after the arrangement is completed, and it is very inconvenient to replace one round and requires a lot of manpower; electronic online advertising players This problem can be solved easily. All outlets arrange programs, change, insert broadcast, and broadcast arrangements only need to be controlled by software on the server management side, and the order can be issued. It can be said that an advertisement can be placed overnight. To broadcast on designated outlets in various cities, the speed is very
