China Touchscreen News, 2021 China backlight display module market status and development trend forecast analysis. The development of backlight display module can be traced back to the World War II period, when ultra-small tungsten lamps were used as the backlight display module of aircraft instrumentation, which was the initial stage of the development of backlight display module. After half a century of development, now the backlight display module has become an electronic independent discipline, and gradually formed a hot spot for research and development.

Backlight display module is closely related to the development of liquid crystal display industry.

Liquid crystal display screen imaging principle is to rely on the electrode in the panel after the electrode is energized, the liquid crystal molecules are twisted, so that the backlight display module light can pass through and realize the light-emitting, while the liquid crystal itself does not emit light, so the backlight display module is an important component of the liquid crystal display screen can be displayed normally. Thus, the development of the backlight display module industry is closely related to the development of the liquid crystal display industry. Data show that in 2014, TFT-LCD display panel shipments of 166 million square meters, increased to 223 million square meters in 2019, with a compound annual growth rate of about 6.07%.

LCD industry to accelerate the transfer to domestic drive the development of domestic backlight display module industry

In the context of the overall global market scale is growing, China is also in the global consumer electronics products and LCD industry plays an increasingly important role, has become a large country in the production and consumption of LCD TVs, computers, smartphones and other consumer electronics products, cell phones and color TVs have accounted for the production of more than half of the world's shipments, and the LCD industry as a key supporting industries are also accelerating the transfer of the LCD industry to the domestic market. Shift.

With the development of China's LCD industry, the industry chain supporting enterprises have also been the corresponding development, the gradual improvement of the industry chain also further support the long-term development of the domestic LCD module industry and backlight display module industry. At present, the upstream and downstream enterprises of the industrial chain of the liquid crystal display industry are also actively investing.

Backlight display module industry development trend

1. Backlight display module is developing in the direction of thin and light, ultra-narrow bezel, and heteromorphism.

In recent years, with the continuous development of emerging consumer electronics technology and the continuous improvement of people's living standards, consumers' demand for ultra-thin design of electronic products "fashionable appearance, lightweight and portable" has become stronger and stronger, prompting more and more high requirements for the screen display, and the screen is getting thinner and lighter, and the backlight display module is also facing the challenge of thinning as an essential part of the liquid crystal display. Backlight display module, as an indispensable part of the LCD screen, is also facing the trend of thin and light requirements. At the same time, with the rapid penetration of full-screen cell phone smartphone market, showing the market to the ultra-narrow bezel screen cell phone development direction, the screen accounted for an increase in the case, the need to cut or dug holes in the basis of the non-anomalous screen, used to place a variety of parts, so the anomalous to become a backlight display module development direction.

2. Backlight display module is to the direction of large size development

In the field of liquid crystal display technology, consumers often need a thinner and lighter appearance, the picture is bigger and clearer, display content is richer products, liquid crystal display technology will continue to develop along this direction. From the point of view of the display interface alone, due to the large screen can bring better user experience in video, game experience, cell phone display size increases year by year. Accompanied by the increase in cell phone LCD screen, the size of the backlight display module also increased accordingly.

3. Backlight display module to the direction of high brightness, high uniformity development

The performance of the backlight display module is mainly examined for its luminous brightness and uniformity, under the same light source conditions, more light can be thrown to the screen to enhance the brightness and enhance the uniformity of irradiation in order to improve the quality of the screen display, thereby enhancing the consumer's user experience. Determine the brightness and uniformity of the backlight display module is the main link for the light guide plate microstructure optical design, light guide plate process manufacturing capacity, and a variety of film reflective, diffusion performance. With the backlight display module for high brightness and uniformity of higher requirements, the backlight display module optical structure design, light guide plate manufacturing capacity puts forward higher requirements.

4. Backlight display module to energy-saving, low-consumption direction of development

LCD display quality is getting higher and higher, the display interface is getting bigger and bigger, the content is getting richer and richer, accompanied by higher and higher energy consumption, more importantly, the endurance of electronic products will also be greatly reduced. Therefore, in addition to battery improvements, the LCD industry also needs to improve the direction of energy saving and low consumption. Backlight display module as the main energy-consuming components, need to make certain improvements, so as to ensure that energy consumption will not rise at the same time to enhance the display function, to effectively meet market demand. In recent years, more energy-saving LED backlighting has been applied in backlight display modules, and is constantly being improved and perfected. Energy saving and low consumption has become one of the important development directions of backlight display module.
