OLED is an organic light emitting diode, or organic semiconductor device.
Its basic structure is as follows: metal cathode, electron transmission layer, organic luminescence layer, hole transmission layer, anode and glass bottom etc.
Generally speaking, OLED has the following advantages: 1.
2. Fast reaction time (1 radical s magnitude);
3. Low operating voltage (3 ~ 10V);
4. Wide Angle (st13 above 170 °);
5. Thickness of the panel (upper 2mm);
6. Low power consumption, medium LCD power consumption is 50%;
7. Working temperature range (40 ~ + 85 ℃);
8. Suitable organic base materials can be used, as well as fully organic flexible devices that can be bent and folded.
At present, the application range of OLED lights is very wide, such as lighting panel for residential and commercial buildings;
It USES OLED "wallpaper" as a large billboard and signboard, even up to 200 square feet.
(I) coloured panel lights for homes and offices and panel lights for large walls and ceilings;
Backlight for large-area LCD TV and display;
Windows, walls and partitions of offices can double as both flat and computer screens.
Yu can also be used as an ultra-light wall-mounted TV monitor.
Leds are linked to OLED.
Then, compared to the two, LED lights can provide high energy efficiency and special long life, but the manufacturing cost is too high, so it is limited in special applications;
OLED lamp is different from LED point light source, it is very thin planar distributed light source, and can be manufactured in large scale, large area and low cost, so new application fields can be developed.
The application of OLED in small and medium-sized screens will come soon. However, the technology is still immature and very expensive in the application of TV screens. In the future, "LCD TVS will still be the market leader in the next 8-10 years.
Nowadays, the stability and encapsulation of OLED materials still need to be improved. OLED is very expensive, and it will be difficult to popularize OLED in the short term if there is no new technological breakthrough.
It is expected that LCD and LED will remain the mainstream technology in the next 10 years.
As OLED technology advances, it is expected to enter the mainstream market gradually, but it may just coexist with LCD and LED and complement each other instead of completely replace each other.
That is: LED people can be quiet to be a handsome man!
Perhaps OLED will enter display and lighting in the next few years, encroaching on some of the LCD and LED market share, and in 10 years' time.
