Analysis of splicing mode and advantages of LCD splicing screen

As the performance setting equipment deployment of large screen industry, LCD splicing screen is now widely used in entertainment, security, transportation, energy, radio and television and other industries. LCD splicing screen can be used differently according to different needs to achieve the effect of single-screen or multi-screen displaying, deal with various defects of traditional TV curtain wall, and provide Z-good large screen for convenient, comprehensive and timely display of video information of various systems, especially for long-distance and timely command, conditioning and other engineering applications. The performance system of the curtain. In terms of application, LCD splicing screen has many performances:

1. Long life and low maintenance cost.

LCD is equipped with long life Z performance. Its life is very long. Even if it is a backlight department with short life Z, it can reach more than 50,000 hours. Even if it takes such a long time to override, it will only affect its brightness. Only by changing the backlight tube, it can recover and shine again. Color. This is different from back-projection in quality. The life of LCD backlight is ten times longer than that of back-projection gallbladder, and its advantages and disadvantages are self-evident.

2. Large visual angle.

For the early LCD products, the visual angle was once a major problem restricting the LCD, but with the continuous advancement of LCD skills, this problem has now been completely solved. The view angle of the DID LCD screen, which is accepted by the LCD spliced curtain wall, reaches over 178 degrees, and has reached the result of absolute view angle.

3. High discrimination rate and bright picture.

The point spacing of liquid crystal is much smaller than that of plasma. Physical discrimination rate can easily reach and override the high-definition scale. The brightness and analogy of liquid crystal are very high. The color of liquid crystal is beautiful and bright. BSV liquid crystal splicing skill is completely curvature-free when it reaches the pure plane, and the image is stable and not shining.

4. Ultra-thin and light.

LCD has the characteristics of thin thickness and light weight, which can be easily spliced and placed. The 40-inch special LCD screen weighs only 12.5KG and is less than 10cm thick, which is beyond the comparison of other performance devices.

5. Low power consumption and low calorific value.

LCD performance settings and equipment deployment, low power, low heat has been praised by people. Small size LCD screen power is not more than 35W, 40 inches above the LCD screen, its power is only about 150 W, only about one third to one quarter of the plasma. Shenzhen LCD splicing screen

6. Mobile and changeable stitching performance combination effect.

LCD splicing screen can be customized according to different user requirements, select single-screen performance, full-screen performance, arbitrary combination of performance, image travel, image overlay and other effects.

7. Unjustified barrier has a long time and low maintenance cost.

LCD is a reliable performance setup equipment deployment for Z-stable Z. Because of its small calorific value, the device is very stable, and will not be hindered by excessive temperature rise of components.

LCD splicing screen not only has vast performance advantages, but also is very mobile in splicing methods. Now Z is a common splicing method in the market, which includes drag-and-drop splicing controller, embedded and PCI card splicing.

I. External Drag-and-Splice Controller

External drag splicing controller can also be called large screen display splicing device or TV wall controller, TV wall splicing device. Its important effect is to divide a complete image signal into N blocks and distribute it to N video display units (such as back-projection units) to complete the construction of a large screen with multiple ordinary video units.

2. Embedded

The principle of embedded splicing screen is that each splicing unit has an independent video disposal penalty module. Through the matrix, complete signals are sent to each unit, and video disposal penalties are held respectively, which branch out the part that should be displayed by itself, and the signal of this part is amplified and displayed to realize the splicing table of large screen. Goals to be achieved. Since each punishment is handled separately, the number of units spliced together can theoretically be infinite.

3. PCI Card Type

The principle of PCI card is to split a complete video image into M*N sub-video signals by using a multi-screen splicing card on an industrial computer, and then transmit these sub-video signals to the corresponding units on the splicing curtain wall separately, so as to achieve the goal of large screen splicing performance. It can support multiple video settings deployed at the same time access, reaching the efficacy requirements of LCD mosaic large screen. "It is called pull-out, because this kind of splicing curtain wall is divided into two independent departments, one is the performance department, which can be composed of ordinary large screen splicing performance units such as LCD splicing screen; the other is the splicing controller, whose function is to achieve the combination of multiple physical outputs into a discriminant superposition. After the performance output, the screen shows a picture.
