标题: (EN) Fingerprint recognition display device
(ZH) 一种指纹识别显示装置
摘要: front page image
(EN) The invention discloses a fingerprint recognition display device. The display device comprises a light guide plate, a light emitting component and a plurality of photosensitive induction units, wherein the light guide plate is arranged on an emergent light face of a display panel, the light emitting component is capable of emitting modulating light which is transmitted between the light guide plate and a display face of the display device by adopting a manner of total reflection, and the photosensitive induction units are arranged below the light guide plate and arranged in an array manner. When a user touches the display face of the display device with a finger, the fingerprint ridge position contacts the display face to destroy the total reflection transmission of the modulating light at the position, and the modulating light is reflected to the photosensitive induction units below the modulating light, the fingerprint valley position does not contact the display face and cannot affect the total reflection transmission of the modulating light, and the photosensitive induction units below the modulating light cannot receive the modulating light, thus, the detection on fingerprint can be realized by the photosensitive induction units on the basis of photodynamic action, interference with inner part of the display device is not liable to occur, the influence caused by the distance between the photosensitive induction units and the display face of the display device is not liable to occur, and high-quality fingerprint detection can be easily realized.
(ZH) 本发明公开了一种指纹识别显示装置,在显示面板的出光面之上设置导光板,可发出在导光板至显示装置的显示面之间采用全反射方式传输的调制光的发光部件,以及设置在导光板下方的呈阵列排布的多个光敏感应单元。在用户手指接触显示装置的显示面时,由于指纹的脊位置处接触显示面时会破坏调制光在此处的全反射传输,将调制光反射至下方的光敏感应单元,而指纹的谷位置处不与显示面接触不会影响调制光的全反射传输,其下方的光敏感应单元不会接收到调制光,因此,通过光敏感应单元基于光敏效应可以实现对指纹进行检测,与显示装置内部部件不易产生干扰,且不易受到光敏感应单元与显示装置的显示面之间距离远近的影响,容易实现高质量的指纹检测。
