With the development of China's economy, splicing screens are becoming more and more widely used. We can all see them in fields such as banks, commercial buildings, and buildings.
Splicing screens usually have four main uses, namely command dispatch, video surveillance, video conferencing and information dissemination. According to the application, the general application field is different, so we can make a choice according to our own needs. There are many types of splicing screens, which can generally be divided into LCD seamless splicing screens, plasma splicing screens, LCD splicing screens, etc. They have functions such as image rotation, OSD input, and multiple logic. superior. The difference lies in the characteristics of the product itself. What are the specific aspects? Today, the editor will compare and analyze with you.
First, the characteristics of plasma splicing screen
1. Ultra-thin and light. The plasma splicing screen has the characteristics of thin thickness and light weight, and can be easily spliced and installed. The 46-inch dedicated plasma splicing screen weighs only 12.5KG and has a thickness of less than 10 cm, which is unmatched by other display devices.
2. Low power consumption and low heat generation. Plasma splicing screen display equipment, low power consumption, low heat has been recognized by users. The power of the small-sized plasma splicing screen does not exceed 35W, and the power of the 46-inch plasma splicing screen is only about 150W, which is only one-third to one-fourth of the plasma.
3. There is no trouble for a long time, and the maintenance cost is low. Plasma splicing screen is currently the most stable and reliable display device. Due to the low heat generation, the equipment is stable and will not cause malfunctions due to excessive temperature of the components.
4. Large viewing angle. For the early plasma splicing screen products, the viewing angle was once a big problem for the splicing screen, but with the continuous advancement of plasma splicing technology, this problem has been completely solved. The DID LCD screen used in the plasma splicing curtain wall has a viewing angle of more than 178 degrees, and has achieved an absolute viewing angle.
5. High resolution and bright picture. The dot pitch of liquid crystal is much smaller than that of plasma, and the physical resolution can easily reach and exceed the high-definition standard. The plasma splicing screen has high brightness and contrast, bright colors, and the plasma splicing technology realizes a pure flat display with no curvature at all, and the image is stable. No flicker
6. Long life and low maintenance cost. Samsung splicing screen is the most durable display device with a long service life. Even the shortest lifespan of the backlight is as high as 60,000 hours, and it will only be bright even after using it for such a long time. If the backlight is replaced, the original bright color can be restored. This is basically different from the rear projection type. The life span of the splicing screen backlight is ten times that of the rear projection bulb, and its advantages and disadvantages are self-evident.
Second, the characteristics of LCD splicing screen
1. The refresh rate of 120HZ multiplier, the 120Hz frequency multiplier liquid crystal display technology of DID products? Can effectively solve the problem of smearing and blurring in the process of fast image motion? Enhance the sharpness and contrast of the image? Make the picture clearer? Not easy to get tired.
2. Due to the color calibration technology developed for DID products, this technology allows the color calibration of dynamic images in addition to the color calibration of still images. This will ensure the accuracy and stability of the image output. In terms of color saturation, DIDLCD can achieve high color saturation of 80%-92%, while the current color saturation of ordinary CRT is only about 50%.
3. The brightness is uniform, the image is stable and does not flicker. Since each dot of the LCD maintains the color and brightness after receiving the signal, unlike the CRT, it needs to constantly refresh the pixels. Therefore, the LCD has uniform brightness, high image quality, and absolutely no flicker.
4. High brightness and high contrast: DID LCD splicing screen has higher brightness, which is different from ordinary TV and PC LCD screen. The brightness of a TV or PC LCD screen is generally only 250~300cd/m2, and the brightness of a DID LCD screen can reach more than 700 cd/m2. The contrast ratio of DID LCD splicing screen is 1200:1, even as high as 10000:1, which is more than twice that of traditional PC or TV LCD screens and three times that of ordinary rear projection. Third, the characteristics of LCD seamless splicing screen
1. The brightness of the light is very strong. When the sunlight is directly on the screen surface within the visible distance, the display content is clearly visible.
2. The automatic brightness adjustment with automatic brightness adjustment function can obtain the best playback effect under different brightness environments. 3. Video, animation, graphics, text, pictures and other information display, network display, remote control
4. Advanced digital video processing, technology distributed scanning, modular design/constant current static drive, automatic brightness adjustment 5. Super gray scale control, 1024-4096 gray scale control, display color above 16.7M, clear and vivid color, three-dimensional Strong sense of product advantage:
1. Low power consumption, light weight
2. Easy to install and can be spliced arbitrarily
3. Long life (usually 50,000 hours or longer)
4. No radiation, uniform brightness, good picture quality
5. Reduce maintenance costs
