Description of electronic seamless splicing and optical seamless splicing of LCD splicing screen
In recent years, the seamless splicing screen technology has been sought after by many users in the commercial display market. The main reason is that its display effect has achieved barrier free display. The physical splicing between screens is eliminated by unique technology. No matter how many large screens are spliced together, it can be perfect from any angle such as front and side. At the same time, Seamless splicing screen technology is also one of the few innovative technology products in the display market in recent years.
At present, there are two kinds of seamless splicing screen technology: one is electronic seamless splicing screen, and the other is optical seamless splicing screen.
1. Electronic seamless splicing screen: the principle of electronic seamless splicing screen is to directly remove the frame of LCD splicing screen and add less than P1 at the seam 5mm light-emitting material, composed of two rows of light beads inside. This light-emitting device will be directly connected to the PCB circuit. A chip is added on the side of the splicing screen to control the LED device to emit light and restore the image obscured by the black frame.
This electronic seamless is a real 0mm gap. It directly removes the black frame, and can also display the picture. The pixel consistency is up to more than 95%.
2. Optical seamless splicing screen: the principle of optical seamless splicing screen is that a layer of optical glass is covered on the surface of the LCD screen, and the four corners of the glass are treated with inclined planes. When displaying the screen, the refraction phenomenon is generated through the light passing through the glass, weakening and hiding the black edge of the splicing screen, so as to achieve the effect of seamless display.
The feature of optical seamless technology is to enable optical glass. As long as there is light, there will be seamless display after the screen is lit. Moreover, the refraction of optical glass weakens only the physical seam of 0.1mm. Even if it does not input the seamless conversion of 0.1mm gap, it is ignored, because the well-known DLP gap is 0.2mm, and now some people are still using DLP. However, DLP has obvious defects such as unclear, atomization, low definition and low brightness. We still like to use LCD splicing screen for indoor LCD splicing. Now it is better to have optical seamless splicing screen.
Conclusion: once the seamless splicing screen technology is launched, it has attracted the attention of the majority of system integrators in the display market. At the same time, according to the feedback of project users, both the maturity and stability of the product have met the requirements of users. I believe that with more people's recognition of seamless splicing screen technology, its share in the display market will be larger and larger in the next step.
