The invention discloses an electronic device. The electronic device is cooperated with a human tissue and includes a body. The body has a sensing area. The sensing area comprises a plurality of sensing units. Each sensing unit comprises a driving line, a signal line, a signal read-out line, a light-emitting element and an optical sensing element respectively. The signal line is disposed staggered with the driving line. The signal read-out line is disposed staggered with the driving line. The light-emitting element is electrically connected with the driving line and the signal line respectively. The optical sensing element is electrically connected with the driving line and the signal read-out line respectively. Wherein, the light-emitting element emits a light toward to the human tissue and received by the optical sensing element to generate a sensing signal.本發明揭露一種電子裝置。電子裝置與一人體組織配合,並包括一本體。本體具有一感測區,感測區包含複數感測單元,各感測單元分別包含一驅動線、一訊號線、一訊號讀出線、一發光元件以及一光感測元件。訊號線與驅動線交錯設置。訊號讀出線與驅動線交錯設置。發光元件分別與驅動線及訊號線電連接,光感測元件分別與驅動線及訊號讀出線電連接;其中,發光元件發出一光線射向人體組織,且被光感測元件所接收而產生一感測訊號。111‧‧‧發光元件112‧‧‧光感測元件D‧‧‧驅動線DL‧‧‧資料線Px‧‧‧次畫素結構R‧‧‧訊號讀出線S‧‧‧訊號線SL‧‧‧掃描線SU‧‧‧感測單元T1‧‧‧第一電晶體T2‧‧‧第二電晶體Vdd‧‧‧第二電壓源Vss‧‧‧第一電壓源
