The reason why OLED technology can be widely used is that compared with other technologies, OLED technology has the following advantages:
(1) low power consumption
Compared with LCD, OLED does not need backlight, and backlight is a part of energy consumption in LCD, so OLED is more energy-saving. For example, the power consumption of 24 in AMOLED module is only 440 MW, while that of 24 in polysilicon LCD module is 605 MW.
(2) fast response
Compared with other technologies, OLED technology has a faster response speed and a response time of microseconds. The higher response speed better realizes the moving image. According to the data analysis, the response speed of LCD is about 1000 times.
(3) wide perspective
Compared with other displays, OLED is active, so the picture will not be distorted in a wide range of viewing angles. Its upper and lower, left and right angle width is more than 170 degrees.
(4) high resolution display
Most high-resolution OLED displays use active matrix, which is AMOLED. Its light-emitting layer can absorb 260000 true colors with high resolution. With the development of science and technology, its resolution will be improved in the future.
(5) wide temperature characteristics
Compared with LCD, OLED can work in a wide range of temperature. According to relevant technical analysis, OLED can operate normally from – 40 ℃ to 80 ℃. In this way, the regional restriction can be reduced and it can also be used normally in extremely cold areas.
(6) OLED can realize soft screen
OLED can be produced on different flexible substrate materials such as plastics and resins. The soft screen can be realized by evaporating or coating the organic layer on the plastic substrate.
(7) the quality of OLED products is relatively light
Compared with other products, OLED has smaller quality, smaller thickness compared with LCD, higher anti-seismic coefficient, and can adapt to larger acceleration, vibration and other harsh environment.
Because OLED has many advantages, OLED technology is more widely used than LCD technology, which can be extended to the field of electronic products, business, transportation, industrial control and medical fields. In addition, in recent years, major international enterprises are constantly strengthening the research on OLED technology, OLED technology will be further improved.
In the commercial field, small size OLED screen can be installed in POS, copier and ATM. Because OLED screen can be bent, thin and anti-aging, it is beautiful and practical. Large screen can be used as business promotion screen, as well as advertising display screen in stations, airports, etc. This is because OLED screen has wide viewing angle, high brightness, bright color, and much better visual effect than LCD screen.
In the field of electronic products, the most widely used OLED is smart phones, followed by notebook, display screen, TV, tablet, digital camera and other fields. Because OLED display screen is more colorful and can adjust the color (different display modes), it is very widely used in practical applications, especially today’s curved TV, widely praised by the masses.
A little VR technology needs to be mentioned here. LCD screen has a very serious drag when viewing VR equipment, but it will alleviate a lot in OLED screen. This is because OLED screen is to light up light molecules, while LCD is to light liquid flow. Therefore, in 2016, OLED screen officially surpassed LCD screen and became the new darling of mobile phone industry.
In the field of transportation, OLED is mainly used for ships, aircraft instruments, GPS, video phones, vehicle display screens, etc., and mainly in small size. These fields mainly focus on OLED’s wide-angle performance, which can clearly see the screen content even without direct vision, LCD is not.
In the field of industry, the industry of our country is developing towards automation and intelligence. More and more intelligent operating systems are introduced, which requires more screens. Whether it is on the touch screen display or on the viewing display, OLED has a wider application range than LCD.
In the field of medical treatment, the influence of medical diagnosis and the monitoring of operation screen are all inseparable from the screen. In order to meet the requirements of wide field of vision of medical display, OLED screen is the “best choice”.
It can be seen that OLED display has a very high development space and huge market potential. However, compared with LCD screen, OLED manufacturing technology is not mature enough. Due to low mass production rate and high cost, only some high-end devices in the market will adopt top-level OLED screen. However, from the data in the first half of 2017, all manufacturers have increased their research investment in OLED technology, and many mid-range electronic products in China have applied OLED displays. From the perspective of mobile phone industry, since 2015, the proportion of OLED screens has increased year by year. Although there are still not many LCD products, the most advanced OLED screens are used in high-end smart phones. Therefore, the development of electronic products such as smart phones is bound to further promote OLED development.
