In the future, touch display will develop in five directions: conformity, high definition, flexibility, diversification of applications and localization of materials.

In the future, touch display will develop in five directions: conformity, high definition, flexibility, diversification of applications and localization of materials.


From the visual presentation effect and other aspects, morphological integration is the future development trend.
As a new type of human-computer interactive input media, touch screen input is simpler, more direct and more convenient than traditional display, keyboard and mouse input. Whether mobile phones, tablets, smart watches and other products, or inquiry machines, KTV jukeboards, all have touch display technology, which has been very popular in our daily life and become an indispensable part.
Full-fit display screen is to completely paste protective glass, touch screen and display screen together in a seamless way, eliminating the air layer between the display screen and touch screen, making the thickness of the screen thinner. Let the visual effect present perfectly, it looks more beautiful, reduces the probability of graying, makes the picture more transparent, enhances the display effect, and also makes the screen thinner. In this way, the full fit is more aesthetic and practical.
Full-fit display is the physical integration of touch screen and display screen, while TDDI is the integration of touch control and display driver. At present, the touch and display functions of smartphones are independently controlled by two chips. The most important feature of TDDI is to integrate touch chips and display chips into a single chip. TDDI is another product innovation in the field of smartphones. Its fundamental requirement lies in the two-way expansion of display function and performance. TDDI technology is the extension of display function, representing the future development trend from complex functional module combination to single multi-functional integrated module. The display effect is more and more focused on the characteristics of human subjective experience, which is also the goal of TDDI chip manufacturers. TDDI chip can reduce display components, reduce complexity and cost, and simplify the supply chain production process. TDDI chip is also an important tool for mobile phone manufacturers to achieve narrower borders and full screen.
Fingerprint identification technology is the mainstream technology of biometric identification technology, which is widely used in all walks of life in the authentication. At present, devices with fingerprint function have to have a physical key to scan fingerprints. With the development of touch display chips, touch control and display are highly integrated. The future trend is to complete fingerprint identification at any position on the screen and embed fingerprint identification into touch display devices. This will not affect the limitations of equipment manufacturers in the design of equipment industry. The integration of fingerprint identification and touch display technology is becoming more and more mature, and its use will be more and more extensive.
With the improvement of user demand, it shows that HD can meet the market demand.
With 5G officially commercialized, 5G+8K era officially coming, the development of Internet era, the change of consumer's concept and the continuous progress of new display technology, consumers put forward higher and broader demand for the visual effect and use of LCD.
Common 2K display technology and emerging 4K display technology can not fully meet the needs of consumer groups for large-scale sports events, telemedicine, security monitoring and other ultra-high-definition display; 8K ultra-high-definition display is considered to be the highest standard in the future ultra-high-definition display era, and has become the highland occupied by the display industry of various countries.
According to the current plan, most panel manufacturers in the early stage of development will develop 60Hz 8K display screen based on amorphous silicon (a-Si) technology, while the next stage panel manufacturers may also develop 120Hz 8K display screen based on oxide technology. The latter has better opening rate and lower power consumption.
According to IHS, a market research institute, 8K ultra-high definition LCD TV will be the first to achieve explosive applications in China. It will exceed 1.4 million units in 2019 and more than 2 million units in 2020.
In the next few years, display technology will develop towards higher resolution technology, wider gamut, higher contrast and faster response time.
