11.3: Distinguished Paper: LTPSbased Transparent AM OLED

14.1” qFHD quarter Full High Definition Transparent Active Matrix Organic Light Emitting Display AM OLED was developed with the well known and reliable technology based on LTPS Low Temperature Poly Silicon backplane. The key concept of the transparent AM OLED display lies on the seethrough window on each pixel so that the objects across the device can be seen. In the design of pixel structure, functional separation of light emitting area and seethrough area was realized on the different regions. The features of transparency and transmitted image quality were investigated and optimized in the design of the pixel structure. Up to 38% transparency of the prototype panel was accomplished with the high transparent cathode material which transmittance was more than 75%. LTPS based Active Matrix and Top emission OLED structure was used for the prototype to provide wide range of color expression, more than 100% of color gamut.
