That is the 0mm seamless LCD splicing screen, which uses third-party pixel compensation.
The metal edge of LCD splicing screen is covered with the patch of the world's narrowest pixel LED with a small pitch of P < 1.5, and the whole process is accurately controlled by computer.
The compensation pixels display the picture information synchronously with the LCD splicing screen, and the consistency between the display color and the LCD screen is as high as 95%.
After the big screen is lit, there is no black edge gap in the whole seamless LCD splicing screen from any angle.
The above is the topology diagram of technical principles.
