LG display 15 inch OLED panel, in 2012 to market the product of 40 inches

South Korea's LG display in the "FPD International 2009" and set the seminar, "OLED TV LCD TV technology development over the direction of the" (October 28, 2009) published speech, introduced the development trend of large size OLED panel and future product plans. LG Kim is responsible for OLED sales and marketing vice president of the stage presentation Won. South Korea LG Electronics will use the LG display panel, in the end of 2009 listed 15 inches OLED tv.

15 inches of product performance parameters, the number of pixels is 1366 x 768, resolution of 105ppi. Full white brightness of 200cd/m2, the peak brightness of 450cd/m2, black brightness of 0.01cd/m2. Through the use of drive components based on SPC (Solid Phase Crystallization) "high-temperature crystallization process of low temperature polycrystalline silicon TFT. The structure of the component is the bottom luminous type. These performance parameters have been published in Korea in October 2009, "IMID 2009".

Kim also talked about future product plans. Plans to market in 2010 to more than 20 inches, in 2011 put more than 30 inches, in 2012 put more than 40 inches of products. He said: "by 2012, although the price of 40 inch products will be quite high, but still able to afford".

2016 cost advantage over LCD

For stable and low to the market to enlarge the size of the OLED panel facing the technical issues, Kim referred to (1) drive element (TFT), (2) OLED material and its film forming process, (3) packaging technology.

(1) driving element, Kim said it would probably be based on SPC or IGZO based low temperature polycrystalline silicon (In-Ga-Zn-O) oxide TFT. However, the use of these two materials TFT need to overcome the problems of large size. Based on SPC low temperature polycrystalline silicon TFT, "has been made clear in support of the sixth generation glass plate size. But to achieve a large size of 40 inches or so, you must also support the eighth generation glass floor. Need to develop SPC processing device capable of performing heat treatment above 700 DEG c". Oxide semiconductor is one of the candidates to achieve large size". However, the current batch of uneven is also very large, so poor reproducibility".

(2) OLED materials, Kim said: "intends to change before the 2011 fluorescent material, and then replaced with phosphorescent material. At the same time, it will start from the mask evaporation technology and promote the research of printing technology". As for (3) packaging, "consider the use of television, it is best to solid packaging". Through these efforts, compared with the LCD panel, will strive to make the material cost of 150% in 2012, the yield reached 70%, in 2016 the cost of materials to reach 70 ~ 80%, the yield reached the same level".

In addition, LG display on the FPD International 2009 exhibition also exhibited a 15 inch product. Although it had been publicly displayed at the Korean domestic exhibition, but also in Japan for the first time in the exhibition.
