The replacement of old and new, natural selection is the law of evolution that we are familiar with, and it is also the inevitable law of many technological developments. As we all know, LCD technology is not a perfect technology. Although it has dominated the display field for several decades and in recent years it has seen significant improvements in color performance and viewing angles, it is still inseparable from the shackles of backlight components. Limits the evolution of display devices. 
How to break through the "wrong" OLED Although the current OLED "impact" is very strong, but many of their "fault" is still difficult to overcome. In fact, OLED technology is not new. Since its inception in 1979, there have been more than 30 years of development history, but some problems have remained difficult to remove until now.
In addition, the low luminous efficiency is also one of the inevitable defects of OLED, especially in the blue light part. The OLED power-saving feature is that when the black screen is displayed, the pixels are not turned on and the power consumption is lower than that of the LCD. However, when the white screen is fully opened, the OLED shows its weak point of low luminous efficiency, which means that it is less power-efficient than the LCD.
Many advantages have also been tying LCD to virtual OLED
Although OLEDs now have the advantages of high contrast, wide color gamut, etc., these advantages are lost on the same cost basis. Because on the basis of the same cost, the traditional liquid crystal technology can achieve the level of OLED through the blessing of some technologies on various data indicators.
Self-luminous represents future but not necessarily OLED
At present, OLED is mainly used in televisions and mobile phones. Take the TV field as an example. We have data that shows that in 2016, global shipments of LCD TVs totaled 142 million units and global shipments of OLED TVs reached 900,000 units. In 2017, global LCD TV shipments are expected to reach 173 million units. Taiwan, OLED TV sales are expected to be between 1.6 million to 1.7 million units.
Although it has nearly doubled its sales volume, OLEDs are still less poor in terms of total sales, and are still not an order of magnitude compared with LCD TVs. From a technical point of view, self-illumination will gradually replace LCD backlights, but self-luminescence is not just OLEDs, such as competing quantum dots.

Can OLEDs really represent the future of display technology?
With the increasing exposure of various OLED screens, it seems that OLED screens have become the focus of the industry and consumers. In the past, OLEDs have always been the focus of industry attention, but there are not many finished products. Today, OLEDs have begun mass production. This kind of screen supply is not only what manufacturers want, but also what many users want. OLED is now widely used in mobile phones
Ultra-thin, self-luminous, wide viewing angle, almost infinite contrast, many of these characteristics of OLED are already familiar. With Apple's adoption of Samsung's OLED screen on the iPhone X, the head of next-generation display technology seems to have been borne by OLED. So, can OLED really represent the future of display technology? How to break through the "wrong" OLED Although the current OLED "impact" is very strong, but many of their "fault" is still difficult to overcome. In fact, OLED technology is not new. Since its inception in 1979, there have been more than 30 years of development history, but some problems have remained difficult to remove until now.
OLED afterimage phenomenon
Recently, there have been quite a lot of OLEDs on the OLED, and afterimages and burning screens have been frequently exposed. This phenomenon is due to the long-term image stillness and strong contrast between the screen and the screen. After the screen was switched, the original bright part There will still be some shadows left in the picture. In a slight situation, this type of residual image will fade gradually, but if you play a still picture for a long time or it accumulates for a long time, it will cause permanent damage and be irreversible, that is, it will cause burn-in. For OLEDs, this is due to the inherent defects of organic materials. Many advantages have also been tying LCD to virtual OLED
Although OLEDs now have the advantages of high contrast, wide color gamut, etc., these advantages are lost on the same cost basis. Because on the basis of the same cost, the traditional liquid crystal technology can achieve the level of OLED through the blessing of some technologies on various data indicators.
Local dimming technology
For example, high-definition LCDs adopt HDR technology and adopt high-density direct local dimming. In addition, IPS LCDs open horizontal viewing angles to more than 160. Although they are still OLEDs in value, the visual gap between consumers is minimal. Turn HDR on and off
We all know that the advantages of OLED in color are obvious, and the color gamut is very wide, but the LCD with quantum dot technology can improve the color and tone of the display screen. Quantum dots can absorb specific spectrum, which usually depends on their size. It can eventually be used or create better colors such as red, green, and blue, giving the user more saturated colors and a wider color gamut. Self-luminous represents future but not necessarily OLED
At present, OLED is mainly used in televisions and mobile phones. Take the TV field as an example.

In 2017, global LCD TV shipments are expected to reach 173 million units. Taiwan, OLED TV sales are expected to be between 1.6 million to 1.7 million units.
QLED has become OLED's biggest competitor
It can be said that the overall situation of OLEDs is still not very optimistic. Although the voice of OLEDs in the mobile phone field is high, the exposed problems have also made more people question the maturity of the technology. Many fatal defects have not been solved so far. solve. So for the current OLED, to achieve higher recognition and more sales, to overcome these defects is the key.
