Presentation Title

Printing OLED Technology for Next Premium TV Application

Presentation Abstract:

 The premium TV market is rapidly shifting from LCD (Non-Emissive Display) to OLED (Emissive Display). Its differentiating factors include exhibiting excellent image quality (C/R, HDR, Viewing Angle, Image Clarity..) and providing the freedom of design (Rollable/Foldable). (Fig.1). However,  the current OLED TV MP technology, such as White OLED+CF(Color Filter) technology, faces technical challenges to meet the market requirement in terms of high resolution (8K) and cost. The printing OLED technology is proving to be as a strong candidate to become the next premium OLED TV mass production technology. Meeting the market demands of high resolution (8k) with high aperture ratio (65” 8K OLED TV, A/R:>50%), the printing OLED technology is also cost competitive due to its simple device structure, material usage, high productivity, and overall lower investment cost as shown in Fig.2

This paper will address and discuss the technical challenges & latest technology breakthrough of printing OLED technology for TV application.
