76‐1: Invited Paper: A New Full Screen Flexible AMOLED Solution with Fingerprint

Abstract

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.

56.1: Invited Paper: Pinhole Matrix Fingerprint on Display Technology for CFOT OLED Display

“…Pinhole-based FOD requires only a sparse array of micrometer sized pinholes, perfectly suitable for CFOT OLED. It has also been demonstrated that this method is capable of producing high resolution fingerprint images beyond the ability of traditional optical FOD [2,5]. In this work, we report the successful integration of pinhole-based FOD with CFOT OLED, achieving high performance on both FOD and display.…”

“…Fingerprint on display (FOD) has become a widely used function in today's OLED mobile phones [1][2][3][4][5]. It provides user with convenience as well as larger screen ratio.…”

36‐5: A Novel FOD Solution with High‐PPI Flexible Sensor under OLED Panel

“…A pinhole image system was integrated in the 6inch OLED panel for the benefits of low thickness, high flexibility, and low dependency of OLED panel transmittance [2,3]. The pinhole array was fabricated in an opaque metal layer with the rest area completely shielded.…”

39‐2: Ultra‐Thin Integrations of Optical Array Sensors with Displays and any Transparent Surface for Fingerprint Imaging and Beyond ‐ toward a Universal Sensor for Display

“…For phones, the most common methods to implement fingerprint identifications include devices that measure either capacitive, or optical, or ultrasonic signals. Although capacitive fingerprint identification possesses advantages like robustness and maturity, it suffers from high cost and small detection areas [4]- [6]. Conventional optical imaging devices that use micro-lenses or collimators to collect the signals are normally thick, and hard to work in sunny outdoor environments from saturations of optical detectors [7]- [8].…”
