>> Comparative analysis of LCD/quantum dot/OLED: a bunch of OLED problems, quantum dots are half dead 31th,July,2018
At present, OLEDs are not fully mature due to their technology, the yield is low, and the industrial chain is not perfect. The scale effect has not yet been formed, and the cost is still high. Moreover, Samsung's RGB OLED and LG's white OLED are different. The so-called white OLED is directly used as a white point OLED device (in fact, a yellow OLED and a blue OLED device are stacked together) as a pixel point source. The red, green and blue color filters filter out the color (similar to the LCD panel). RGB OLEDs are different in that each pixel produces its own RGB color by itself, without the need for a filter.
White OLED technology is low in technology, fast in mass production, high in profit, and beautiful in appearance. This is also the technology adopted by LG's leading OLED camp. The current OLED color TV market is full of TV products that are all white OLED technology. And if RGB OLED is used for large-screen production, the technology is complicated and difficult to mass-produce, and the yield is extremely low. LG Samsung has no good solution. This is why Samsung, Hisense and TCL are not willing to launch OLED TVs.
There is also a natural defect that OLED is currently very important: burnt screen.
But even if LG uses white OLED yield is not good, the cost has always been high. Moreover, not only the yield cost problem, white light OLED has insurmountable defects, that is, residual image, low brightness, large power consumption, short life, and poor pixel quality.
Many OLED TVs in shopping malls require that tellers can't put on the program of the logo, can't always put a still picture, and need to rest for a long time.
Comparative analysis of LCD/quantum dot/OLED technology: a bunch of OLED problems, quantum dots are half dead
And don't just see white light OLED problems, even Samsung's current production of RGB OLED is the same as burning screen, green line. Since Samsung's own s series and noto series enabled the OLED panel to start burning, the problem has not been broken, and the afterimage is accompanied by the mobile phone for a lifetime.
In addition to the cost factor, the problem of burn-in after the burn-in is more serious for the display. For example, the resident task bar at the bottom of the screen, the resident icon of the desktop, etc., is not a serious burnt screen, which is one of the reasons why OLED does not dare to involve the display.
to sum up
LG's LCD panel business was hit hard, with annual shipments falling and profits plummeting. However, it is not a very good idea to immediately hope that the transformation of OLEDs is still a problem. In the case of Samsung's two core technologies of quantum dots and OLEDs, the current LCD panel has not yet been shaken. The transitional propaganda of OLEDs and quantum dots in these years has led to the expectation of consumers, and the result is presented to consumers. A product with many defects. For now, even in the future, it is not realistic for OLEDs and quantum dots to win LCDs. Don't always publicize the new panel, or do you honestly solve the actual problem.
