Why are there seams on LCD video wall?
The basis of LCD video wall is LCD panel, which is formed by pouring liquid crystal molecules between two glass substrates. Due to the need for "sealing", there will be borders around the LCD panel, which leads to black seams when multiple screens are spliced.
LCD splicing seam distance:
3.5mm joint: formed by the right side frame 1.8mm of the screen and the left side frame 1.7mm of another screen.
1.8mm joint: formed by the right side frame 0.9mm of the screen and the left side frame 0.9mm of another screen.
0.88mm joint: formed by the right side frame 0.44mm of the screen and the left side frame 0.44mm of another screen.
Does the LCD splicing screen have 0 seams?
Due to the LCD screen itself, there is liquid inside and it needs to be protected by a frame, so it is impossible to achieve complete seamlessness with current technology, but according to current technology, a fake "0mm" seam can be achieved. The LCD screen splicing achieves the effect of a near 0mm seam, not by physically eliminating the frame, but by using special technical means to achieve a visually seamless effect.
Why is 3.5mm the most common LCD splicing screen?
The technology is mature and stable.
The 3.5mm splicing seam is one of the earliest technical specifications to be commercialized on a large scale in the field of LCD splicing screens.
Balance between cost and performance
From the perspective of cost performance, the 3.5mm bezel has achieved the best balance between display effect and cost. Compared with ultra-narrow bezel products such as 0.88mm and 1.7mm, the price of 3.5mm bezel is lower, but it can meet the display needs of most scenarios.
Wide application adaptability
The 3.5mm splicing LCD splicing screen covers a variety of scenarios from monitoring, exhibition halls to conferences. It has a variety of sizes (46, 49, 55, 65 inches) and can be flexibly spliced into large screens of different sizes.
How to quickly distinguish LCD and LED video walls?
Screen structure
Usage scenarios and brightness
LCD is suitable for medium and short distance indoors (such as conference rooms and monitoring centers), with high color reproduction, but the brightness is usually lower than LED.
LED screens are extremely bright and are often used outdoors or in strong light environments (such as billboards and stages), and have no viewing angle restrictions.
Cost Difference
The cost of small-pitch LED splicing screens is significantly higher than that of LCDs, while low-end LED advertising screens may be cheaper, but the picture quality is rough.
Conclusion
The above are the problems that buyers often encounter when building an LCD video wall in 2025. For merchants who want to wholesale LCD video walls, the above questions and answers can help you avoid many problems and buy the LCD display that suits you.
