OLED is a multilayer organic thin film structure to produce electroluminescent devices, it requires a low driving voltage, these key features make OLED in meeting the application of flat panel displays appear to be very prominent. OLED display than LCD is thinner, brighter, lower power consumption, faster response, high definition, good flexibility, high luminous efficiency, to meet the new consumer demand for display technology. And now more and more display manufacturers around the world have invested in research and development, greatly promoting the industrialization of OLED.
OLED screen has a very high contrast ratio, response speed and color saturation, OLED liquid crystal display with high resolution, thin, light weight, low energy consumption, long life, no radiation advantages! Using this OLED screen does not require a backlight, and its transparency is far better than the traditional LCD backlit box-type OLED screen.
In the diversified flat panel display market is seen as a very promising new display product. Can be applied to a very wide range of business environments. But we can't deny the importance of LCD. In airports, restaurants, hospitals, banks, schools, hotels, supermarkets, etc., indoor and outdoor, we can see the figure of LCD. It is closely related to our life. And LCD support customize the solution according to the customer's requirements,like LCD touch kiosk, self terminal kiosk, LCD advertising totem, information kiosk etc., which makes it very versatile and easy for people to use it. While OLED is different, it is just a screen, a OLED screen, there is no way to accept the customization of other accessory features, why OLED screen is much more expensive than LCD screen?
1. OLED color gamut is wider, the picture is more vivid color gamut is higher, the more vivid the display color. In principle, the use of LED backlight LCD screen can achieve a very high color gamut. But because the vast majority of manufacturers are using the general effect of WLED backlight, resulting in the mainstream LCD screen color gamut lags behind the OLED display.
2. OLED can be thinner than LCD screen OLED self-luminous, unlike LCD as the need for backlight, structural differences, so that OLED can be thinner than LCD screen.
3. Response speed, OLED is also seconds to kill LCD for displaying fast moving objects, OLED than LCD also has the advantage of seconds level. In picking up the game console to play games, watch action movies, sports events, very advantageous.
4. OLED flexible bendable. the advantages of the flexible bendable characteristics of the OLED screen, can be elaborated from the current and long-term respectively. In the short term, it seems that curved OLED TVs can already be bent into curvature. For the TV such a large size of the screen, curved screen has the innate advantage of allowing users to have a better sense of field and visual envelope.
In the past, LCD is technically difficult to achieve curved screen, while in the OLED era, there are already very mature curved screen TV products. In the long run, OLED's flexible and bendable characteristics can also make smart devices full of imagination. Combined with OLED thin characteristics, perhaps the future screen can be made into a form of paper, can be bent and folded at will, which is unimaginable in the LCD era.
5. Contrast slaughter LCD. black display perfect, dark details perfect all OLED TV in the technical conference display, will display this full of stars "Star Map", you know what the reason is?
Because this starry sky map want to realistic good, such as the requirements of the screen has a very good black bit (that is, the minimum luminous brightness) and excellent contrast. Only the black bit and contrast is good enough to show the purest broken black and dark details, and contrast with the bright star point to bring a strong visual impact. There is a statement that the contrast ratio of OLED is infinite, this statement is not true. the contrast ratio of OLED is at the million level, while the contrast ratio of mainstream LCD is about a thousand, the difference reaches a thousand times. Such a spike level gap makes LCD in the display of black and deep dark scenes are not in place.
