In recent years, with the increasingly fierce competition in the domestic mobile phone market, many manufacturers have had to upgrade their products in an all-round way, including the optimization of mobile phone screens. This also pushes panel manufacturers to accelerate their own level of technology research and development to a certain extent, so as to break through the bottleneck and truly promote the upgrading of screen products, in order to jointly promote the improvement of product competitiveness with terminal manufacturers and help upgrade and expand the terminal market.
"Black technology" solves the problem of high refresh and high energy consumption
Since 2019, in addition to the popularity of 5G technology, another trend change in the mobile phone industry has focused on the screen field - the screen with high refresh rate is gradually popularized in smartphone products. To some extent, the high refresh rate of mobile phone screens is also related to the arrival of 5G technology. The improvement of network transmission speed has spawned higher quality video and game content, which also puts forward new requirements for display technology.
Therefore, since 2019, mobile phone manufacturers have begun to try to carry high refresh rate screens on the latest products. In May of that year, the flagship mobile phone oneplus 7 Pro released by OnePlus used a 90Hz refresh rate screen. Previously, the refresh rate of general flagship mobile phone products was mostly 60Hz.
Since its development, high refresh rate screens have become standard. Huaxi Securities research reports that solutions with high refresh rates, from 90Hz to 120Hz or higher, will become a new hot model choice. But at the same time, problems such as high power consumption accompanied by high refresh rate screens also plague mobile phone manufacturers and consumers. For panel manufacturers, how to optimize the use experience of high-refresh rate screens has become the next issue that needs to be overcome.
At the 2021 SID Display Conference in the United States, TCL Huaxing exhibited "Full LTPS 15Hz ~ 144Hz Broadband Display Technology" for the first time. The significance of this technology is that in different use scenarios, it can achieve intelligent switching of the dynamic refresh rate of the screen, thus bringing a balance between the use experience and energy consumption. From the data presented by the conference, compared with the current mainstream products, TCL Huaxing's ultra-broadband display at a 15Hz refresh rate has reduced the peak brightness jitter by more than 4 times, the maximum brightness jitter is less than 0.5%, and there is no flickering phenomenon on the screen. This means that users can not be interfered with by factors such as screen flickering in low-frequency usage scenarios, ensuring a good use experience to the greatest extent.
Data from the laboratory shows that when applied to small products such as mobile phones, 15Hz is displayed compared to 60Hz, and the power consumption can be reduced by 9.6%, and the mainstream products are calculated by 10 hours of standby time, and the comprehensive standby time can be extended by about 1 hour. This also means that TCL Huaxing's broadband display technology can maintain mobile phone products at a relatively low energy consumption level, thereby solving the problem of high energy consumption of high refresh rate screens to a certain extent, and providing a solution for the current "volume and volume" mobile phone battery life problem.
Therefore, when mobile phones and other products are equipped with this broadband display technology, when entering different use scenarios, the refresh rate will also be dynamically adjusted, such as in the voice call or music playback and other static pictures, the refresh rate will be correspondingly reduced to ensure effective energy savings.
Mobile phone panel recovery, how manufacturers respond to new demand
TCL Huaxing is a pioneer in "precautionary planning" in broadband display technology. In 2019, TCL Huaxing has launched a mobile phone panel that can achieve 30Hz-120Hz dynamic frame rate switching with the help of dynamic frame rate technology at the first World Display Industry Conference. Today's technology has achieved an update and upgrade on the basis of the original.
Behind the technological upgrade, the diversified product line provides a foundation for TCL Huaxing to stand firm in the mobile phone panel market.
At the 2021 AMERICAN SID Display Conference, in addition to the "full LTPS 15Hz ~ 144Hz broadband display technology", TCL Huaxing also launched a series of leading products, including a 6.53-inch 110% NTSC mobile phone screen, a 6.3-inch super full screen, a 6.53-inch camera mobile phone screen, a 6.67-inch AMOLED cloud scroll screen, and a 6.67" teardrop-shaped YIR3 inner folding screen.
As can be seen from the product name, these panel products are aimed at the needs of users in different forms. Each mobile phone manufacturer can also use different TCL Huaxing panel products according to its own market positioning and user portraits, and finally launch the corresponding mobile phone terminal products.
According to the global quarterly mobile phone tracking report launched by the market research agency IDC, the global smartphone market shipments in 2021 will be 1.3548 million units, an increase of 5.7% year-on-year, and the recovery and growth of the smart phone market and the full popularization of 5G technology will further promote the synchronous development of the upstream and downstream industry chain of mobile phones. According to a latest research report by market research firm Strategy Analytics, the global smartphone display panel market achieved $46 billion in revenue in 2021, and the annual revenue growth of smartphone display panels exceeded 5%. When Korean companies and Taiwan companies gradually withdraw from the market, this will provide greater development space for domestic panel manufacturers.
If production capacity is the basis for panel manufacturers to compete in the market, then technological innovation has become an important thrust for panel manufacturers to stand out in the market. Huaxi Securities quoted the Report of Liding Industry Research Network in the research report that the current global mobile phone display panel main capacity supply is still based on a-Si (amorphous silicon) LCD and LTPS LCD, on this basis, LCD applications are developing towards several dimensions, one dimension is to continuously expand the market towards the professional display field, and the other dimension is to increase the added value of products through continuous innovation in the application of smart machine display.
For TCL Huaxing, the introduction of innovative technologies such as "full LTPS 15Hz ~ 144Hz broadband display technology" will help them further meet the needs of the smartphone industry for panel technology applications. It is also foreseeable that with the further recovery and development of the smartphone industry, similar technological innovations around the panel field will appear more frequently.
