In daily life, we must keep the habit of “cleaning” the LCD advertising machine regularly. You can spray it on the LCD advertising machine screen with a special potion, and then gently wipe it with a clean white cloth. Try not to use a damp cloth with too much water content. Too much water content on the damp cloth can easily cause water to stay on the screen. Water entering the screen through the edge can cause a short circuit in the system and the LCD advertising machine cannot work normally. It is recommended to use soft scrubbing materials such as glasses cloth and lens paper to scrub the screen to avoid unnecessary scratches on the LCD advertising machine screen. The working environment of the LCD advertising machine directly affects the operation and service life of the LCD advertising machine. If the working environment of the LCD advertising machine is too bright, or even direct sunlight, this will not only affect the visual communication of the LCD advertising machine, but also damage the LCD advertising Machine screen electronic components. The air humidity of the working environment where the LCD advertising machine is located must be kept suitable, and two extremes must not be taken. Once the electronic equipment is too humid, it will only affect the circuit conditions and cause the LCD advertising machine to fail to work normally. No matter how good electronic products are, they will have their own longest operating time, and LCD advertising machines are no

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.

Improve the contrast of the LED display: Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. Increase the gray level of the LED display: the gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest of the single primary color brightness. The higher the gray level of the LED display, the richer the color , The color is brighter; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. Nowadays, many LED display manufacturers can set the gray scale of the display to 14bit~16bit, so that the image level can distinguish the details and the display effect is more delicate, vivid, and colorful. Narrowing the dot pitch of the LED display: narrowing the dot pitch of the LED display can greatly improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of ​​the LED display, and the more details that can be displayed More, the screen display is more delicate and lifelike. The combination of LED display and video processor: The LED video processor can use
