Company News >> The advantages and disadvantages of OLED display and LCD display 16th,May,2018
                                              OLED display technology is considered as an almost ideal display technology and is an alternative to the popular LCD liquid crystal display technology. Therefore, understanding the OLED display technology requires careful understanding of the main differences between OLED display technology and LCD liquid crystal display technology.
In fact, the topic of replacing OLEDs with OLEDs is now mainly referring to active TFT-AMOLED technology instead of TFT-LCD technology. Both are active drive technologies and drive technology uses thin-film transistor circuit structures. However, due to the phase difference between the two technology systems, the display performance, product technology, applicable conditions, and cost factors of OLED and LCD have great differences.
First of all, OLED is much more perfect than LCD technology in display performance: it mainly includes OLED which has 3-5 times the contrast of LCD, more than 40% of the color range of LCD technology, OLED has a perfect viewing angle experience, and has more than LCD. Thousand times faster response, higher brightness per unit power consumption, true black display, higher dynamic resolution with equivalent physical pixel density, one-third LCD screen thickness (Theoretically OLED can manufacture 1 Mm thickness television). It can be said that in the main display indicators, OLED does not have less than LCD products. If you really want to find out some technical deficiencies, mainly reflected in the life factor (currently LCD's life is significantly higher than the OLED products, which is the LCD technology and OLED is the only one advantage) - but the lifetime of the OLED The level is also rising.
In the second product process, OLED technology has lower material consumption and fewer engineering steps. This is the most important reason people believe that OLED will become an LCD replacement technology. In addition to the material and process requirements are nearly 1/3 lower than the LCD, the OLED processing process is much simpler than the LCD. According to relevant data, OLED displays require 86 processing steps, while LCD screens require more than 200 steps.
From the product structure, LCD display products must include backlight components (light sources, light guide plates, reflectors, diffuser plates, prisms, and frames, etc.), LCD arrays, and TFT drivers. The OLED display technology only requires the oled array and the TFT driver. The difference in the structure of the TFT driving parts of the two is not significant, mainly reflected in the material and process of the thin film transistor may be different, but it can be made without any difference, using the same technology and materials. In terms of main and new materials LCDs and OLED arrays, the solid nature of OLEDs makes the overall structure and process flow simpler.
Third, OLEDs also have great advantages in terms of adaptation. OLED is a solid display, which is different from the liquid properties of LCD, so it is more insensitive to temperature and pressure, and can adapt to the needs of a wider temperature and pressure environment. OLED's viewing angle is more than double that of LCD, making OLED suitable for wider viewing angle applications. OLED is an autonomous light-emitting product. Black is particularly prominent, and it is suitable for higher-brightness light emission. Therefore, in the dark, or in high light conditions, they are eager to create devices that are ideal for display.
