Since last year, the emergence rate of OLEDs in related reports in the display industry has been increasing. This new term has really caused many people to confuse them with LEDs with only one word difference. On the other hand, although OLED is currently mainly targeted at small-size screen applications such as mobile phones, in the field of professional large-screen display, some LED companies have already smelled the smell of gunpowder. So, what is the sacred OLED that is being fired? What is the connection with LED? Why do LED companies feel threatened?
The concept of LED and OLED
The well-known LED display technology is a display method in which LEDs (light-emitting diodes) are directly used as pixels. The color LED display is composed of red, green and blue LEDs, and is arranged in a dot matrix. The LED display usually consists of a display module, a control system and a power supply system. The control system controls the LEDs to emit light of different colors and then images. Since the diameter of the LED is large, the distance between pixels of the same color is also large, forming a dot pitch.
OLED (Organic Light-Emitting Diode) emits light by driving an organic film with current. The light emitted by it can be red, green, blue, white, etc., and can also achieve full color effect.
To put it simply, the LED and OLED technologies have different illumination principles, different materials, but all have self-luminous characteristics, and do not require a backlight, so they can be called thin display technology. In addition, flexible OLED displays can be bent, curled, or even folded.
In what ways can OLEDs threaten LEDs?
At this year's various professional display equipment exhibitions, OLED commercial displays have begun to show off. The focus of the industry in the large-screen display industry is mainly focused on the direct competition of OLED displays and LCD monitors and LCD splicing. In the face of the rapid rise of OLEDs, LED displays are also difficult to stay out of the way.
Small-pitch LED displays are the most likely type of product to cross the OLED business. In fact, the birth of the small-pitch LED display is mainly to solve the problem of "into the room" of the LED screen. After reducing the pixel pitch, zooming in on the visible distance, and solving the problems of low-light, high-gray, etc., the small-pitch LED screen finally came into the room, in the control room, command and control room, studio, theme park, stage background and other large-format videos. The wall field has become a big hit, impacting the status of DLP.
However, the addition of OLEDs has injected unrest factors into the three-legged pattern of DLP, LCD, and small-pitch LEDs. In terms of small and medium size, 55, 65-inch OLED commercial displays are currently available, which will compete with LCD and small-pitch LEDs in the mainstream size class, while the unique flexible and flexible properties of OLEDs bring subversive display. Means, especially for the creative display field represented by the digital signage industry, is extremely lethal.
In addition to showing the confrontation at the terminal level, the threat of OLEDs to LEDs is also manifested in: OLED lighting competition for LED lighting. It should be noted that the commercial display market is a relatively niche market, and its healthy development largely needs to be supported by a larger mass consumer application market, just like LCD TVs for LCD monitors and LED LEDs for LED displays. . Obviously, the potential threat of OLEDs to LEDs is not only in "leaves" but also in "roots."
In the face of the strength of OLED, can LED stabilize its position?
In the field of large-screen splicing, the biggest advantage of small-pitch LED display screens is that it has no natural seam-free characteristics. At least at present, OLED is difficult to achieve single-screen large-scale, so its application in the field of large-screen splicing is natural. Be subject to the restrictions of seams. Moreover, in the large-screen field, the small-pitch LED screen can also be used for surface mounting and profile mounting. Obviously, in large-size applications, the flexible and flexible characteristics of OLEDs are difficult to transform into exclusive advantages. In this sense, LEDs still have obvious advantages in applications where the seaming requirements are high. In the field of large-screen creative display, OLED may compete with LEDs on the same stage, but it is hard to say alternative.
Of course, the technical problem is not a problem at all, and new display technologies are always emerging. This returns to the fundamentals of display technology services, which is to meet the needs of users, solve user problems, and help users generate value. Therefore, LED screen companies may wish to dilute the hardware competition, on the one hand continue to dig deep into the application value of small-pitch LEDs, on the other hand, to do their homework at the service level, to achieve the "soft" service value enhancement, to create hardware parameters, A more lasting competitive advantage.
What can the Screen Protector Cutting Machine do?
This is a customized universal cutting machine that can cut Screen Protectors and Back Filmns suitable for mobile phones,
iPads, smart watches, macbook etc.
One Cutting Machine can cut all types of Mobile Phone Screen Protectors. The cutting accuracy is 0.1mm. It can cut more
than 22000+ mobile phone models and styles, and any model can be cut. 0 inventory, no need to worry about large
inventory, to meet the large needs of customers.
In the Mobile Phone Screen Protector industry, in order to meet the requirements of consumers in the traditional mobile phone film business model, many practitioners will prepare a large number of Mobile Phone Screen Protectors for popular mobile phones. However, the alternate iteration of new and old mobile phone models is too fast, and the cycle is greatly shortened, resulting in many screen protectors that have not been able to be sold in time, and can only be disposed of by themselves. and profit margins will suffer as a result. It is against this background that the Screen Protector Cutting Machine was born, and its appearance can improve the operating status of the Screen Protector industry.
