Samsung Electronics reportedly has no plans to purchase quantum dot OLED panels from Samsung Display for the production of OLED TVs. Samsung Electronics would find that the brightness of screens based on the panels is not high enough.
The Samsung Electronics division that deals with televisions currently has no plans to use qd-oled panels, Business Korea writes, based on an industry source who is said to be familiar with the matter. There are two reasons for this: on the one hand, the finding that qd-OLED panels do not achieve the brightness desired by Samsung Electronics and, on the other hand, concerns about the risk of burn-in at the panels.
The Korean medium bases that point of clarity on Lee Choong-hoon, a former Samsung researcher and the current CEO of UBI Research. According to him, not yet achieving the desired brightness level of the qd-OLED panels means that it is difficult for Samsung Electronics to purchase these panels, because the company attaches great value to the screen brightness. The peak brightness can easily reach 1500cd / m² or higher with the more expensive QLED LCD televisions from Samsung, which is roughly twice the peak brightness of the current consumer OLED TVs.
The value that Samsung Electronics attaches to a high screen brightness would also be one of the reasons why the company would mainly focus its capabilities on micro-LED TVs in combination with quantum dots. Screens based on this technology would have little or no burn-in and can theoretically achieve a high brightness. Unlike LG Display’s OLED panels that form the basis of all current consumer OLED TVs, QD OLED TVs use blue OLEDs and quantum dots. In addition, red and green ‘filters’ are used for the color conversion, to create sub-pixels of those colors.
Both Samsung and LG have already released large screens based on microleds, but these are not yet products suitable for consumers. There are also a number of technical obstacles to overcome, such as lowering pixel pitch, improving the production process and increasing yields. At the beginning of this year, Samsung already showed four microled TVs for home use, which were televisions with sizes of 75, 88, 93 and 110 inches. Samsung could release its first microled TVs next year, but it will likely be several years before microled TVs become available to consumers in decent numbers and at reasonable prices.
Despite the alleged doubts of Samsung Electronics, sister company Samsung Display is investing heavily in QD OLED technology. According to research firm Omdia, Samsung Display would not only have supplied prototypes of quantum dot OLED panels to Samsung Electronics, but also to Sony and Panasonic. According to sources, TCL would purchase qd-oled panels from Samsung Display in the first half of next year. The Chinese TCL also seems to bet on several horses, as the company may next year show a qd-oled TV based on an inkjet printing method, which the company is developing in collaboration with the Japanese Joled.
