The advantages and disadvantages of OLED and LCD, the difference between OLED and LCD

Secondly, in the product process, OLED technology has lower material consumption and fewer engineering steps. This is the most important reason why people believe that OLED will become an alternative technology for LCD. In addition to the requirements for materials and processes that are nearly 1/3 lower than that of LCDs, the processing technology of OLEDs is also much simpler than that of LCDs. According to relevant data, OLED display module require 86 processing procedures, while LCD screens require more than 200 procedures.

From the product structure, LCD display products must include backlight components (light source, light guide plate, reflective plate, diffuser, prism and frame and other components), LCD array and TFT driving part of three aspects. The OLED display technology only needs OLED array and TFT drive part. There is little difference in the structure of the TFT driving part of the two, which is mainly reflected in the differences in the materials and processes of the thin film transistors, but they can also be made with the same technology and materials without any difference. In terms of the main and new materials LCD and OLED arrays, the solid characteristics of OLED make its overall structure and process flow simpler.

Third, OLED also has great advantages in adapting conditions. OLED is a solid display, which is different from the liquid properties of LCD, so it is more unclear about temperature and pressure, and can adapt to the needs of a wider temperature and pressure environment. The viewing angle range of OLED is more than double that of LCD, making OLED suitable for wider viewing angle applications. OLED is an independent light-emitting product, the black performance is particularly outstanding, and it is suitable for higher brightness light-emitting. Therefore, it is eager to produce devices with ideal display effects under dark or high-brightness conditions.

On the other hand, OLED products can be made in a variety of bases-this is due to the characteristics of OLEDs that are solid-state displays, so OLEDs can be manufactured into special display products such as flexible display devices and transparent display devices. In addition, the simple structure of OLED itself can still play its unique advantages in close-to-eye display (helmet aiming equipment).
