1. Optical seamless LCD splicing screen
The working principle of the optical seamless splicing screen is to install a layer of optical glass in front of the LCD screen. The four corners of the glass are treated with bevels. When an image is displayed, the refraction phenomenon caused by the light passing through the glass is on the black side. Hide and weaken seamless display. In fact, the optical seamless splicing screen has a physical edge with a 0.1mm black border, but after light refraction, the angle of the 0.1mm slit can be seen to become blurred. At present, the optical seamless LCD splicing screen is upgraded to the second-generation product, and the glass adopts a flat design, and the seamless display effect is better.
2. Electronic seamless LCD splicing screen
The electronic seamless splicing screen technology adopts the direct removal of the LCD splicing screen frame, and the LED lighting device is added on the top. There are two rows of lamp beads inside, and the lighting material is connected to the PCB line in the splicing screen and added through the side of the splicing screen. The chip controls the lighting of the LED device and restores the image that is obscured by the black frame.
Whether it is input seamless splicing screens, they have their own advantages and disadvantages. Optical seamless LCD splicing screens have low cost. Only a physical gap of 0.1 mm can be hidden and weakened to achieve a seamless splicing effect, which is not possible with traditional 1.7 mm LCD splicing screens. Comparable but it also has a small flaw. Although the second-generation optical system is designed with flat glass, the lighting is not serious for the first generation, but there is still a little, and sometimes a gap of 0.1mm is displayed; seamless LCD splicing screen It works well in seamless LCD splicing screens. It can achieve 0mm seamless display, but the price is much higher than the optical seamless splicing screen. Generally speaking, it is suitable for products with a good budget and a seamless effect.
In general, the introduction of seamless LCD splicing screens is a revolution in the LCD splicing screen industry, which solves the black border problem of traditional LCD splicing screens.
