For this reason, the absence of color difference has become a key publicity method for some LCD splicing manufacturers in their marketing promotion.Is it true that LCD splice screen is not easy to appear color?In fact, the color attenuation coefficient will also appear after the LCD splicing screen is applied for a period of time, and this kind of attenuation coefficient is irreversible, but its attenuation coefficient is not always generated, and for this, many manufacturers have certain adjustment methods, so as to reasonably increase the use period.
