A 0.6 mm side Narrow Bezel Back‐Plane (BP) was developed and applied in the 5.5 inch flexible AMOLED display for getting nearly 100% screen‐to‐body ratio. In order to achieve narrowbezel display, the VSS signal line on the side of GOA area, which was patterned at source/drain layer, has been patterned on the top of GOA area with an additional metal layer instead. By analyzing the impact of this second...
A mapis matrix has been integrated in the back plane of flexible AMOLED to form a high performance light path for the fingerprint sensor. Mapis fingerprint shows reasonable optical image properties and reliabilities.
To integrate the function of finger‐print recognition within the OLED display panel, a light‐shield (LS) metal layer is incorporated underneath the buffer layer to form fingerprint image on the sensor based on the principle of puncture‐forming picture. Since the LS metal layer is underneath the LTPS TFT, it has some impact on the IV performance of the p‐type LTPS TFT. It has been shown that the floating...
In order to improve the bending resistant of flexible AMOLED display, the stress of thin film should be well researched. In this paper, we analysis the defect of transversal line, which was very serious after module bending, metal crack was found in the process of TFT backplane. We solved the issue of metal crack by adjusting the stress of the backplane compound film. The bending resistant of the...
A mapis matrix has been integrated in the back plane of flexible AMOLED to form a high performance light path for the fingerprint sensor. GOP technology is applied to make the fingerprint unit as lower as possible in the cell phone. GOP IC's bump should be distributed uniformly for mechanical strain.
Recent progress has been reported regarding high color gamut
blue QDs development, improvement of QLEDs performance
including efficiency and lifetime, and development of printable
