Lejin Display (LGD) has gradually reduced its investment in large-size active matrix organic light-emitting diodes (AMOLEDs) and has turned its attention to the transverse electric field effect (IPS) thin film transistor liquid crystal display (TFT-LCD).
Due to the delay in the large-volume AMOLED mass production challenge and the overall large-size panel demand slippage, LGD has slowed down into large-size AMOLED R&D and changed its IPS TFT-LCD security card to stabilize the large-size panel market.
According to industry analysts, the global demand for large-size panels is generally poor this year, and the turmoil in the next year will lead to conservative investment in large-size products and R&D strategies. In particular, AMOLED is limited by the nature of the material itself. To increase the panel size, it is necessary to pay a small price to improve the yield, which will be inconsistent with the current panel factory's strategy of strictly controlling capital expenditure. Therefore, LG Gold will continue to focus on improving the yield of 4-inch AMOLED production lines in the newly opened 4.5-generation plant in the short term, rather than rushing to mass-produce large-size AMOLED panels, so as not to be emptied in the face of unstable market demand.
Because the medium and large size AMOLED panels have to overcome the high cost of the metal evaporation process and are not as good as the IPS TFT-LCD in terms of resolution, brightness and battery life, they are still in the technology development stage. At present, the largest size of AMOLED panels that can be mass-produced is mounted on the Galaxy Note's 5.3-inch smart phone. Whether it can be mass-produced over 7 inches in the next 1-2 years, it can be regarded as an indicator of AMOLED technology breakthrough. .
Industry insiders stressed that AMOLED is indeed a promising next-generation display technology. However, the current application market is still limited to smart phones below 4 inches. If you can score 7 or 10 inch tablets later, it is possible to further Developed towards large-size panels for television.
