Description
Technical field
The present invention relates to a kind of thin-film transistor display panel, especially in regard to a kind of film crystal with optical finger print identification
Tube face plate, and optical finger print identification is more incorporated into thin-film transistor display panel.
Background technology
Biological identification is as all ID authentication mechanisms, it has to be possible to reach the ability of identification and authentication,
It is the specific characteristic by differentiating biology, with accurate screens and confirm correct identity, most common biological identification
Feature includes the biological identifications features such as fingerprint, face picture, iris, voice, smell, palm shape, vein, but the biological characteristic of many of which
When being recognized, the biological characteristic point that different biological identification features needs differs, and the method judged is also not to the utmost
It is identical, for example, when carrying out iris identification, it is necessary at least pick out 240 characteristic points, the identification of fingerprint only needs about 50
Characteristic point, theoretically, the accuracy of iris identification should be higher than that the accuracy of fingerprint, but because the characteristic point that need to be recognized is more,
Required identification module is of high cost, and therefore, refers to also without rapid, the convenient and intuition of identification of fingerprint on usage behavior
The evolution of line technology and the emphasis that improvement is still presently relevant biological identification technology, and another advantage of identification of fingerprint, then
It is that fingerprint template is minimum inside all biological characteristics, it is however generally that, the Template Information amount that one piece of fingerprint needs accounts for 120~
180 bytes, this can allow finger print information to be easily stored in the terminal installation of limited capacity, such as chip credit card, E-Passport, core
Piece identity card etc., such advantage can allow consumer by personal information with walking.
Current developing identification of fingerprint technology is mainly comprising semiconductor-type, optical profile type and ultrasonic type, still, ultrasonic wave
The stage that identification of fingerprint technology still develops in the early stage, technical costs can not decline；Therefore, at present using semiconductor-type and optical profile type as
The identification of fingerprint technology of mainstream.Wherein, the common application principle of semiconductor-type fingerprint sensor has RF capacitance sensings, feeling of stress
Survey, thermal sensing etc., principle are that the micromation sensor such as highdensity capacitance sensor or pressure sensor is integrated in one
In chip, when fingerprint presses chip surface, inside micro capacitance sensor can be assembled according to fingerprint peaks and troughs and be generated
The different quantities of electric charge (or temperature difference) formed fingermark image.Optical fingerprint sensor is earliest fingerprint collecting equipment, is utilized
Light source, Mitsubishi's mirror, the camera of charge coupled cell form a set of fingerprint collecting equipment, after profit presses with finger Mitsubishi's mirror, refer to
The peaks and troughs of line obtains one piece of fingermark image for the absorption and destruction of total reflection, then via camera module by image
It captures and exports, this is also the framework and principle that all optical fingerprint sensors are copied now.Due to the acquisition of optical profile type
Mode be contactless chip in itself, that is, at fingerprint pressing be made of optical elements such as acryl or glass, therefore light
The advantage of formula maximum is exactly cheap and durable, but it the shortcomings that be that volume is larger, it is difficult to apply in hand-held device.
Based on the bottleneck that the prior art is met with, the present invention provides a kind of thin film transistor (TFT) face of optical finger print identification in screen
Plate can be embedded in thin-film transistor display panel, and by the light path of uniqueness design that environment light source and intense light source is greatly reduced
Interference in identification of fingerprint.
The content of the invention
It is a primary object of the present invention to which the total reflection light path of directive property light is designed in panel, to provide fingerprint
Required optical signal during identification, in the environment of the interference of any light, the identification of fingerprint can be effectively performed.
The secondary objective of the present invention is Photosensing Units being integrated on thin film transistor base plate, effectively to reduce, thin
Change the sensing area and thickness of identification of fingerprint, to apply the display in various portable electronic products or various thinnings design
On.
Another object of the present invention is to provide a kind of optical finger print identification thin-film transistor display panel, most panel
Plug-in element is arranged in time display area by product to the fingerprint receiving area as fingerprint, to realize full screen display
Identification of fingerprint panel.
To reach above-mentioned purpose and effect, the present invention provide a kind of thin-film transistor display panel of optical finger print identification in screen,
It is assembled in a backlight module and has main display area and time display area, the film of optical finger print identification in screen of the invention
Transistor display panel includes a light source, a light guide base plate, a colored optical filtering substrates, a thin film transistor base plate and light sensing member
Part, to provide a directive property light, the fingerprint receiving area of light guide base plate is effectively pressed light source with for finger, is come
Light guide base plate is entered to from signal ingress area from the directive property light of light source and be totally reflected and generate optical signalling, eventually certainly
Light guide base plate is left in signal export area, and enters in Photosensing Units and completed with converting optical signals into electric signal
The fingerprint characteristic identification of finger.Due to the present invention by the light with specific directive property as the optical signalling light of identification of fingerprint
Source, and to ensure the transmission validity of optical signalling by way of total reflection, therefore can reach fingerprint in the screen of full screen display and distinguish
Know effect, while by the way that Photosensing Units is integrated in thin film transistor base plate, more can reach the mesh of panel thinning, downsizing
's.
