Abstract
The utility model discloses the light-emitting-diode panels that optical finger print in a kind of screen recognizes, it is conducted in the way of total reflection in light guide base plate by the directive property light that light emitting diode provides, fingerprint with induction pressing in fingerprint receiving area, electric signal is converted optical signals by Photosensing Units, to distinguish the feature of fingerprint.Due to directly utilizing light emitting diode as light source, more usable photodiode is as Photosensing Units and is incorporated into the shading layer region of light-emitting-diode panel, the purpose of integration Photosensing Units can be realized there is no need to increase the area of substrate, in addition, since the surface of almost entire light guide base plate can provide the area touched as fingerprint, thus improve the convenience used.Because directive property light can be by specific optical microstructures to adjust light path before entering to Photosensing Units, therefore in the case of generally use, the influence of the direct light of environment or strong light can be preferably minimized, to ensure the accuracy of identification of fingerprint.
Description
Technical field
The utility model is related to a kind of light-emitting-diode panels, especially in regard to a kind of shining with optical finger print identification
Diode panel, and optical finger print identification is more incorporated into light-emitting-diode panel.
Background technology
Current developing identification of fingerprint technology includes mainly semiconductor-type, optical profile type and ultrasonic type, wherein semiconductor
Formula and the identification of fingerprint technology that optical profile type is more ripe technology and existing mainstream.Wherein, semiconductor-type fingerprint sensor
Principle is that the micromation sensor such as highdensity capacitance sensor or pressure sensor is integrated in a chip, is pressed in fingerprint
Press chip surface when, inside micro capacitance sensor can according to fingerprint peaks and troughs assemble and generate the different quantities of electric charge (or
It is the temperature difference), form fingermark image.Optical fingerprint sensor is collectively constituted a set of using light source, optical element, photoelectric sensor
Fingerprint collecting equipment, profit press with finger, and the peaks and troughs of fingerprint obtain one piece of fingerprint for the absorption and destruction of total reflection
Image, then by image capture and output to achieve the effect that differentiation.Since the acquisition mode of optical profile type is contactless chip itself,
Namely it is to be made of optical elements such as acryl or glass, therefore the maximum advantage of optical profile type is exactly price at fingerprint pressing
It is cheap and durable.
And be typically to be independently arranged identification of fingerprint on current running gear, because be can not to integrate display work and
Identification of fingerprint work is carried out at the same time, therefore by the independent region setting of identification of fingerprint, part dealer be set to running gear back-cover or
Side, so design often result in due to less meeting ergonomics and accidentally touch or be difficult to the awkward situation incuded, therefore have part industry
Identification of fingerprint is set to the non-touch-control region of running gear Touch Screen by person, and if the disadvantage is that, moral conduct moves dress at dark
When the finger print identification function set, which obviously shows then quite not convenient.
Gradually ripe with the technology development of light-emitting-diode panel, the utility model then can using light emitting diode itself
Luminous characteristic, and in combination with the technology of optical fingerprint identification shines two with provide optical finger print identification in a kind of screen
Pole pipe panel, can be embedded in light-emitting-diode panel, and designed by unique light path be greatly reduced environment light source with
Interference of the intense light source in identification of fingerprint.
Utility model content
The main purpose of the utility model is that the total reflection light path of directive property light is designed in panel, to provide

Pole pipe provides directive property light, and so there is no need to light source is additionally arranged.
The another object of the utility model is to use photodiode as Photosensing Units, and is integrated in luminous
In diode base plate.
A further object of the utility model is to provide a kind of optical finger print identification light-emitting-diode panel, most face
Plate suqare is to the fingerprint receiving area as fingerprint, while the screening in light emitting diode base plate is arranged in Photosensing Units by collocation
Photosphere region, therefore can realize the identification of fingerprint panel of full screen display.
To reach above-mentioned purpose and effect, the utility model discloses the light emitting diodes that optical finger print in a kind of screen recognizes
Panel, with main display area and time display area, the light emitting diode face of optical finger print identification in the screen of the utility model
Plate includes a light emitting diode base plate, a light guide base plate and a Photosensing Units, and light emitting diode base plate has multiple luminous two
Pole pipe, and an at least light emitting diode, to provide a directive property light, the fingerprint receiving area of light guide base plate is with for finger
It is effectively pressed, the directive property light from light source enters to light guide base plate from signal ingress area and is totally reflected simultaneously
Optical signalling is generated, leaves light guide base plate from signal export area eventually, and is entered in Photosensing Units to turn optical signalling
It is changed to electric signal and is recognized with the fingerprint characteristic for completing finger.
Since the utility model is optical signalling light source of the light as identification of fingerprint that will have specific directive property, and lead to
The mode of total reflection is crossed to ensure the transmission validity of optical signalling, therefore can reach identification of fingerprint effect in the screen of full screen display,
Simultaneously by the way that Photosensing Units to be substantially correspondingly arranged to the shading layer region of light emitting diode base plate, therefore do not influence not only
