[AMDp1-11L] Effect of Barrier Layer Properties of LTPS TFT Devices on AMOLED Short-term Image Sticking Performance
LTPS TFTs, AMOLED, short-term image sticking, barrier layer, surface roughness
As evidenced by our correlation analysis, reducing barrier layer roughness enhances AMOLED short-term image sticking performance. The results of microwave photoconductivity and interface trap density test demonstrated an reduced defect state density of polysilicon as the roughness of barrier layer decreased, leading to improved short-term image sticking performance.
