OLED lighting, replacing LED is in the not too distant future

At SID2014, it was proved that OLED lighting has competitiveness in terms of efficiency and can compete with LED for the general lighting.

Konica Minolta developed 131lm/W OLED lighting panel last March. It also released an OLED lighting panel with efficacy of 139lm/W at the SID 2014 and drew more attention. Panasonic also presented on OLED, and drew more attention unveiling a prototype in Author interview.

Considering that the efficacy of currently commercialized LED lighting is about 80~130lm/W, it is analyzed that the fruitful result at the SID 2014 showed the potential of the OLED lighting becoming the general lighting instead of the LED lighting.

The most concerned issues of the OLED lighting are lifetime and cost. For the general lighting, 40,000hr, which the OLED panel makers target, is estimated enough considering replace period of the lighting, but the issue is the cost. Compared to the LED, the OLED lighting is expensive and currently forms a high-end lighting market. However, it is inevitable to down the cost for entering the general lighting market. Although LG Chem. announced a price reduction to 200$/Klm from 600$/Klm, investment of the OLED lighting makers in mass-production is vital to reform the general lighting market with the OLED lighting.

The OLED lighting panel has reached the level equal to the LED lighting. Now is the time that the OLED lighting panel companies make a turning point and can leap again by investing as they did with display.

did with display.

Their detailed specifications were not publicized but assumed to be 8.4” and 10.5” with WQXGA (2560 x 1600) resolution. It is forecasted that M6 will be used in the unveiled AMOLED panel for the tablet PC which is an upgraded luminescent material from one used in Galaxy S5. Phosphorescence red and green of DS-Hi-Metal and Cheil Industries Inc. are applied to the M6 material.

Samsung has been focusing on the tablet PC area as a major business from early this year and expects that the tablet PC will become a device experiencing unprecedentedly rapid growth in IT history as display penetration rate for the tablet PC increases fast.

Samsung already launched 7.7” Galaxy tap, which adopted 7.7” AMOLED panel in 2011.

[SID 2014] Latecomers catching up aggressively

AMOLED latecomers; BOE, AUO and Tianma are rapidly catching up the AMOLED development of Samsung Display (SDC) and LG Display (LGD) at SID 2014.

BOE expressed possibility of investing in TV following mobiles by displaying 55” FHD AMOLED panel. In terms of technology readiness level, it is incompatibly lower than panels of LGD and SDC though, it is considerably fast that it was developed in six months and produced in a pilot line in Hefei.

AUO showed that its AMOLED technology had reached at certain level by unveiling 5.7” WQHD (513ppi) ultra-high resolution AMOLED panel. More attention drew towards AUO’s panel because its production method is RGB+FMM as SDC uses and the high resolution is realized with real RGB strip type rather pentile. AUO also expressed its will on AMOLED business by showing 5” HD flexible AMOLED panel and 1.6” AMOLED panel for a smart watch.

Tianma also unveiled 5.5” HD AMOLED panel. Its performance lags behind the current AMOLED panel, but it ai    ms to supply middle-end and low-end panel targeting mass-production of 5.5” FHD AMOLED through continuous R&D.

Challenges of Chinese and Taiwanese makers become serious in the AMOLED market, where Korean makers, SDC and LGD, are dominant, and the latecomers are about to invest in the sector. Thus, it is expected that the AMOLED industry will constantly grow.
