Problems solved by technology

However, when the array substrate and the color filter substrate are aligned to form a box, due to the limitation of alignment accuracy, alignment deviation is very easy to occur, and alignment deviation will cause light leakage, lower transmittance and other defects; if the black matrix is ​​made Wide enough to avoid these problems, but will lose the transmittance of the panel and increase the cost of the backlight
