2021 China's Backlight Display Module Market Status And Development Trend Forecast Analysis
Jul 21, 2021
The development of backlight display modules can be traced back to the Second World War, when ultra-small tungsten filament lamps were used as backlight display modules for aircraft instruments. This was the initial stage of the development of backlight display modules. After half a century of development, the backlight display module has now become an independent electronic subject, and has gradually formed a research and development hotspot.
Backlight display modules are closely related to the development of the LCD industry
The imaging principle of the liquid crystal display screen is that after the electrodes in the panel are energized, the liquid crystal molecules are twisted, so that the light of the backlight display module can pass and realize light emission, but the liquid crystal itself does not emit light, so the backlight display module is a liquid crystal display screen Important components that can be displayed normally. Therefore, the development of the backlight display module industry is closely related to the development of the liquid crystal display industry. According to the data, the shipment area of TFT- LCD display panels was 166 million square meters in 2014 and increased to 223 million square meters in 2019, with an average annual compound growth rate of about 6.07%.
The accelerating transfer of the LCD industry to the country drives the development of the domestic backlight display module industry
In the context of the continuous growth of the overall global market, my country is also playing an increasingly important role in the global consumer electronics and LCD industry, and has now become a major producer and consumer of consumer electronics such as LCD TVs, computers, and smartphones. , The production of mobile phones and color TVs has accounted for more than half of global shipments, and the LCD industry, as its key supporting industry, is also accelerating its transfer to the country.
With the development of my country's LCD industry, supporting enterprises in the industry chain have also developed correspondingly, and the gradual improvement of the industry chain has further supported the long-term development of the domestic LCD module industry and the backlight display module industry. At present, upstream and downstream enterprises in the LCD industry are also actively investing.
The development trend of the backlight display module industry
1. Backlight display modules are developing in the direction of thinner, ultra-narrow bezel, and profiled
In recent years, with the continuous development of emerging consumer electronics technology and the continuous improvement of people’s living standards, consumers have become increasingly demanding for the ultra-thin design of electronic products that are "fashionable, light and portable", prompting people to demand more and more screen displays. The higher the coming, the thinner and lighter screens, the backlight display module, as an indispensable part of the liquid crystal display, is also facing the trend of thinner and lighter. At the same time, with the rapid penetration of full-screen mobile phones into the smartphone market, showing the market's development direction towards ultra-narrow bezel screen phones, as the screen ratio increases, cutting or digging on the basis of non-shaped screens is required. It is used to place various parts, so profiled becomes one of the development directions of backlight display modules.
2. Backlight display modules are developing in the direction of large size
In the field of liquid crystal display technology, consumers often need products with a lighter and thinner appearance, a larger and clearer screen, and a richer display content. Liquid crystal display technology will continue to develop in this direction. From the perspective of the display interface alone, since large screens can bring better user experience in video and gaming experience, the size of mobile phone displays has increased year by year. Along with the increase of the LCD screen of mobile phones, the size of the backlight display module has also increased correspondingly.
3. The backlight display module is developing in the direction of high brightness and high uniformity
The performance of the backlight display module is mainly tested for its brightness and uniformity of light emission. Under the same light source conditions, more light can be projected to the screen to improve the brightness and the uniformity of illumination, thereby improving the quality of the screen display, and then Improve the user experience of consumers. The main links that determine the brightness and uniformity of the backlight display module are the microstructure optical design of the light guide plate, the manufacturing capability of the light guide plate, and the reflection and diffusion properties of various film materials. As the backlight display module has higher requirements for high brightness and uniformity, higher requirements are put forward for the optical structure design of the backlight display module and the manufacturing capacity of the light guide plate.
4. Backlight display modules are developing towards energy saving and low consumption
The display quality of liquid crystal displays is getting higher and higher, the display interface is getting bigger, and the content is getting richer and richer. Accompanied by higher and higher energy consumption, more importantly, the endurance of electronic products will also drop significantly. Therefore, in addition to improvements in batteries, the liquid crystal display industry also needs to improve in the direction of energy saving and low consumption. The backlight display module, as a main energy-consuming component, needs to be improved to enhance the display function while ensuring that the energy consumption will not increase, so as to effectively meet the needs of the market. In recent years, more energy-saving LED backlights have been used in backlight display modules and are constantly being improved and perfected. Energy saving and low consumption have become one of the important development directions of backlight display modules.
