在近日的MWC上海展會上,京東方副總裁劉曉東宣佈,京東方LCD屏下光學指紋感測技術已經研發成功,於今年年底量產。隨後,京東方在日前深交所互動易平臺上回答投資者提問時表示,“公司屏下指紋和螢幕發聲技術目前有幾種解決方案,部分方案已有相應樣品,產品化方案目前與終端品牌客戶持續溝通中。”再次印證此事的真實性。
資深行業觀察家董敏在接受採訪時表示,現在光學屏下指紋都是AMOLED螢幕,LCD實現屏下指紋後肯定對OLED產生很大衝擊。首先,這意味著未來用戶也會花更少的預算用到配備屏下指紋技術的手機,因為LCD的成本和OLED差距較大。董敏分析說,從市場上銷售的手機終端產品來看,同樣的配置的手機,採用OLED比使用LCD高出約30%-40%的價格,這一數字在面板的成本端還會差更多。其次,儘管屏下指紋目前多應用在中高端機型,但長遠來說,屏下指紋會得到進一步的普及,LCD屏下指紋也促進了該技術在中、高、低端機型的全面普及。
近年來,隨著蘋果手機開始採用OLED螢幕,OLED螢幕逐漸成為中高端手機的螢幕首選。除了OLED具有廣色域、高對比度、省電等優勢之外,還因其簡單的螢幕構造更適合應用一些手機解鎖技術,比如現在廣為流行的屏下指紋技術。
對於此次京東方推出LCD屏下指紋技術,北京交通大學教授徐征在接受記者採訪時表示,面板廠商總是在不斷通過創新來創造變化,吸引眼球促進消費。他認為,目前只有中高端手機可以負擔較高成本的OLED手機螢幕。LCD屏下指紋量產之後,可適用的手機價格區間相對較大,LCD螢幕既有可以媲美OLED螢幕的高端型產品,也有適用於低端手機的經濟型產品,搭配屏下指紋技術後仍然如此,這無疑是為低端手機使用屏下指紋敞開了大門。(新聞來源:中國電子報、電子資訊產業網)
