The ultra narrow edge of the LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to achieve unified processing of multiple high-speed video signals, fundamentally replacing the plug-in splicing controller and solving the problem of limited VGA signal input.

Clarity, brightness, and color saturation are the three important performance indicators of liquid crystals. The ultra narrow edge LCD splicing unit has the characteristics of high definition, brightness, and high color gamut. Due to the use of backlight as the light source, the edges of LCD screens are generally wider. The edge width of a 40 inch ordinary LCD screen exceeds 11 mm. If used for splicing, the splicing gap should be at least 22 mm, which affects the visual effect.

The LCD splicing wall adopts a narrow edge structure design of the LCD screen, with the edges reduced by more than twice, which does not affect the visual effect when used for splicing. The edge of the LCD splicing screen is extremely narrow, and the number of splicing can be freely selected (row (m) X column (n)). There are also multiple options for screen size to meet the needs of different applications.

The ultra narrow edge of the LCD splicing screen can be personalized according to the requirements of different users, and functions such as single screen display, full screen display, and any combination display can be selected. In response to the issue of inconsistent LCD screen and driver circuit parameters used in LCD splicing screens, the Tianjin LCD splicing screen ultra narrow edge system adopts adjustment functions for brightness, contrast, chromaticity, and white balance. After debugging, the parameters are automatically saved, ensuring the color consistency and brightness uniformity of the entire splicing screen.

Compared with rear projection splicing walls, LCD splicing walls have low heat value, no radiation, no flicker, no harm to the eyes, and no harmful substances, making them a new generation of environmentally friendly and healthy splicing walls. LCD display technology is currently one of the most excellent flat panel display technologies. The lamp tube of the LCD splicing unit for ultra narrow splicing screens has a service life of over 60000 hours and a long time.
