For backlights, the benefits of LED are first of all energy-saving, and its photoelectric efficiency is twice or even higher than that of CCFL. Secondly, LEDs only need low voltage drive and consume less power. When the power consumption of the liquid crystal display reaches 10W or less, it can be driven by USB (USB3.0), which will trigger the update of the desktop display. Third, LEDs do not contain mercury, which can reduce environmental pollution. LEDs will definitely pose a threat to CCFL, and the maturity and popularity of the former will become a new driving force for the LCD industry. The difference between the two in the diaphragm structure is that the LED system has higher backlight efficiency. LED applications have brought subversive changes to the backlight. 3M has developed a backlight system that does not require a light guide or diaphragm, or even both. The new light guide plate is a 0.2mm thick plastic film. With the LED light source, it can basically replace the functions of the original light guide plate, diffuser plate and prism film, so that the backlight thickness of the small liquid crystal device can be reduced by more than half, and the assembly is also more Simple. One of the diaphragms uses a nano-glue with a refractive index close to the air, and a material such as a diffusion sheet, a prism film, and a reflective polarizer that had to be separated by air before, is bonded into a single diaphragm, so that the conventional diaphragm cannot be realized. System structure. The transmittance of the liquid crystal glass panel is very low, and about 95% of the light is wasted on the liquid crystal panel. The polarizer can only transmit 50% of the light, and the other 50% of the light becomes dissipated as heat on the polarizer. 3M blocks the diaphragm in front of the polarizer and recycles the 50% of the light that has not passed through until it passes through the polarizer. This recycling mechanism, we call it light recycling, light recycling. We now have a program with major TV manufacturers, including some high-end models and LED models. This is a win-win situation, TV manufacturers have increased the scope of product use, reducing design difficulty and material costs. Our advantage is that the product line is very wide, combining many different technologies, namely platform crossing. There are many competitors, but we are the first to make this diaphragm. In terms of liquid crystal diaphragms, major manufacturers are manufacturing optical gain and more integrated diaphragms. Many of the ultraviolet rays in the earliest fluorescent TV backlights made the plastic yellow. Many of our diaphragms are glued to the layers and the glue is more unstable than plastic and is more prone to yellowing. At this time, the adhesive platform was used to develop an ultraviolet-resistant glue, which was then applied to the diaphragm, which had the best yellowing resistance in a fluorescent television. Now flat-panel TVs have LCD TVs, plasma TVs, and OLED TVs in the future. Some products for OLEDs can reduce optical loss, increase brightness and extend OLED lifetime. Others are waterproof. In terms of large display screens, there are more 3D glasses, and we use brightening technology to support the 3D TV's picture effect. In the small display such as mobile phones, a set of naked-eye viewing 3D technology is provided. It relies on a special optical structure and diaphragm to divide the light into the left and right eyes, one picture can only enter the left eye, and the other picture can only enter the right eye. The focus now is on energy savings. Consideration is being given to how to reduce the loss of the Earth's environment throughout the life cycle, using some material-saving applications. In the production and manufacturing sectors, it is necessary to reduce energy consumption and environmental pollution, making the products lighter and thinner. Our new philosophy is to save as much material as possible in the backlight while maintaining the same functionality. For example, in an LCD TV, using air as a light guide plate can make the TV lighter, thus eliminating the need for steel structure support. Cancel the use of air for the light guide, and it will not work without any modification. We have used some unique technology to allow light to diffuse fully in the air. The technology uses a 0.1 mm thick diaphragm to completely reach the optical display of existing TVs. China's first LCD panel backlight module optical film project--Shanghai Kaixinsen functional film industry project was officially put into operation at the end of July. They produced a variety of diaphragms, including diffusion film, brightness enhancement film, and backlight film. The entire industry chain is very wide. Now many Chinese local enterprises are directly involved in the production of optical products. With the advancement of technology, the localization rate of products will be higher, the cost will be lower, the industrial ecological chain will be more perfect, and localized procurement can be realized. At present, the upstream supporting infrastructure of China's liquid crystal display industry is relatively weak. Chinese companies should pay attention to the research and development of new backlight technologies and new products, and do a good job in talent accumulation to give full play to the value of talents. Now flat-panel TVs have LCD TVs, plasma TVs, and OLED TVs in the future. Some products for OLEDs can reduce optical loss, increase brightness and extend OLED lifetime. Others are waterproof.
