屏下指紋辨識成主流,面板雙虎搶商機!群創近期發表外掛式光學式屏下指紋技術,執行副總丁景隆表示,群創除了竹南T3廠外,高雄路竹LTPS廠也積極備戰,2020年放量可期;友達則在日前發表全螢幕光學內嵌式指紋掃描LTPS面板,搶高階智慧型手機面板商機。
隨著智慧手機高屏佔比成為市場主流後,傳統正面指紋模組逐步被淘汰,轉移至手機背部的使用體驗又不佳,屏下指紋辨識備受市場矚目。研調機構TrendForce預估,2019年屏下指紋辨識在手機市場滲透率滲透率有機會突破20%。
屏下指紋辨識技術以光學式與超聲波為主流,超聲波技術是高通所開發,目前和GIS業成、歐菲光合作,穿透性強,手指濕或髒都能清楚辨識。光學式技術成熟、成本低,支援OLED等智慧型手機。
群創TFT sensor事業處處長李淂裕指出,屏下指紋辨識技術依感測面積大小與屏幕整合度,可分為三個階段:外掛單點式屏下指紋辨識、外掛全屏式屏下指紋辨識,以及內嵌全屏指紋辨識。目前晶圓廠製作的外掛單點式屏下指紋辨識,如台積電、三星、中芯等晶圓廠所生產感測元件,成本高且無法與面板技術整合,因此沒有實際全屏指紋辨識感測器相關技術。
李淂裕表示,群創開發面板製程大面積影像感測器技術,取代晶圓單點式影像感測元件,設置於OLED顯示屏下方,實現外掛式屏下指紋辨識傳感器,目前積極洽談特定客戶,預計今年第三季送樣,明年第一季量產,可望搶下這波屏下指紋辨識市場成長商機。 (新聞來源:工商時報)
