Regarding the professional term “backlight”, most people don’t know what it is. Even if they do, few people will know. The function will also be different.
There are currently three types of backlight materials. Some backlights are made of black and white glue, some are made of black vinyl, and some are even made of black and silver glue. .
Generally, there will be black and white double-sided tape on the backlight. Therefore, the backlight using the black and white double-sided tape as the material can generally play the role of adhesive and avoid light exposure. Because of the black and white double-sided tape, generally, whether it is dimming or lighting, it can be easily covered. Because the backlight of this material has the effect of shading, people often call the backlight a shading sheet or a black-and-white film.
The other kind of backlight is made of black vinyl. The backlight of this material can still play a fixed role, but the light shielding effect will be better.
Finally, there is a backlight made of black and silver glue, which has a reflection function that the other two backlights do not have. However, not many people know about this material in Sunshine Courtyard, and there are relatively few places where it can be used.
At present, a detailed survey has been done on the sales of backlight sources of various materials in the backlight source market. According to the survey data, the current market is more popular with consumers, or the backlight source made of black and white glue. The reason why black-and-white glue-based backlights are sold most is that on the one hand, they are well known to consumers, and on the other hand, their functions are what people need.
