In the past two years, the continuous shrinking of LCD splicing screens and the rapid rise of small-pitch LED displays have challenged the market application status of DLP seamless splicing screens. It has become an indisputable fact that application market share has been eroded. Suddenly, the decline of DLP seamless splicing screens became widespread. So, has the DLP seamless splicing screen really reached the “place where heroes are useless”? The answer is of course no. In the high-end large-screen display market that focuses on image quality, DLP seamless splicing screens are still the mainstream. Take the power industry as an example. Driven by the tide of social informatization, the construction of power informatization continues to accelerate-with the help of informatization means, the unified management of specialized functions such as grid dispatching, operation mode, relay protection, and communication can be realized. This means that in actual operation, the power dispatch center needs to monitor and monitor all the data, environmental parameters, and images of each substation, understand the situation of each station in real time, and be able to respond to emergencies in a timely manner. With a huge and complex power supply line, if you want to ensure the accuracy of monitoring information, a fine screen display will naturally become a guarantee. DLP seamless splicing screen not only has the unique advantage of “zero” stitching, it guarantees the exquisiteness of the display screen, but also can display static images for a long time to meet the continuous monitoring needs of

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.

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
