What is the backlight

Backlight (BackLight) is a light source located behind the liquid crystal display (LCD), and its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). The liquid crystal display itself does not emit light, it displays graphics or characters as a result of its modulation of light.

Black and white glue for backlight

The rise of the TFT industry in mainland China has affected the investment eyes of the entire upstream supporting material manufacturers. The series of TFT panel and LCD module investment cases in Mainland China have made Japan, South Korea, and Taiwan, who have experience in upstream material production technology, all follow the pulse of TFT investment in Mainland China. For the key material backlight industry, Japan, South Korea, Taiwan, including mainland Chinese companies, the competition among backlight module companies has reached a fierce stage... It is especially worth mentioning that CCFL tape is even more star-studded, gathering all over the world Top-tier suppliers 3M., Nitto, Sekisui, Siwei, and South Korean Tapes are stationed in mainland China. The huge CCFL business opportunities will accelerate the localization of the TFT industry in mainland China, which will increase the cost of backlight materials a lot. The excellent innovation of adhesive technology, the current domestic high-quality material 3G-BW650M black and white double-sided adhesive has won wide acclaim in the industry for its high-quality quality, stable production capacity, and comprehensive service. It has won everyone's trust.......

Bonding technology in LCD backlight industry

·3G-BW650M black-and-white double-sided adhesive is mainly used in the backlight source to fix and shading (shielding the edge light and light from the lamp position), also called shading film, black-and-white film, or black-and-white adhesive for short.

·Compared with the backlight source used by TFT-LCD, the shading requirements are higher, so most of the black and white glue is applied to the backlight source of TFT-LCD.

·In addition to black and white glue, there is also black vinyl (black on both sides), the main function is still to fix and shading; black silver glue (black on one side, silver on one side), in addition to shading, the silver side has a reflective effect. Relatively black and white glue is the mainstream product in the market.

Characteristics of 3G-BW650M black and white double-sided tape

·Mainly fixed and shading. Relative to this feature, its own characteristics in production and use are mainly manifested in stickiness.

·The viscosity of the black surface and the white surface of the black and white glue is larger. The white surface needs to be larger because the white surface is connected to the rubber frame, and the black surface is connected to the glass. Compared with the adhesion of the glass to the glue, the rubber frame is worse, so the white surface is needed. The viscosity is greater to ensure the stability of the entire module. This is also a feature that the client is relatively concerned about when introducing it.

Market demand for 3G-BW650M black and white glue

·Since small-size TFT LCD modules are mainly used in mobile phones and MP3/4/5 terminal products, the annual production volume of mobile phones and MP3/4/5 is basically the demand for black and white double-sided tapes in the entire backlight industry.

· my country is expected to produce about 800 million mobile phones this year, which is one-third of the world's mobile phone output, while MP3/4/5 will basically have about 300 million units, which is more than half of the world's output.

·The average production of 300-500 small-size backlights requires one square meter of 3G-BW650M black and white double-sided tape, and the annual demand is about 30-40 million square meters.
