Clearly, Samsung hopes to re-enable OLED technology: use a blue light-emitting organic layer to excite quantum dots, and red and green pixels through blue light. Compared with the previous quantum dot LCD TVs, the advantages are: independent viewing angle and high contrast. Compared with the previous quantum dot OLED TV, the advantage is that the color is very rich. Furthermore, quantum dot OLED combinations (QD-OLEDs) are very energy efficient because the complete light from the blue "OLED backlight" is used here for image generation. On the other hand, in an LCD TV, two-thirds of the light is filtered by the color filter, so it cannot be applied to the display.

In addition, QD OLEDs also require a yellow reflector that prevents ambient light from exciting and releasing the quantum dots even if the underlying organic layer does not illuminate. The quantum dots of the red and green sub-pixels are printed in the pixel grid, while the organic light-emitting layer is applied to the large-area surface. It consists of various organic layers, however, these organic layers can realize unstructured vapor deposition economically and efficiently by a CVD (Chemical Vapor Deposition) method. As a result, it is not necessary to accurately position the metal mask in production and move on a large television substrate. Unlike the technology used in smartphones, there is no loss of any expensive organic material when the luminescent layer is applied. These two factors, combined with other reasons, have led Samsung to no longer develop its 2013 OLED TV with red, green and blue organic dot matrix.

According to relevant information, Samsung hopes to redesign the 8th generation LCD factory for OLED TFT substrate production. In this way, Samsung can quickly launch mass production. For example, the first batch of samples will be available in the middle of 2019, and 25,000 substrates will be produced each month. If each substrate can cut 6 TV screens, it will produce 150,000 TVs per month. By 2020, production capacity will double. However, Samsung also needs to overcome some technical obstacles. Samsung plans to apply organic materials to Canon coating machines and print quantum materials through Kateeva machines.

How much is this QD OLED TV worth? It has not yet been finalized. As long as it is not higher than the current OLED price, it is acceptable.
