Description

Organic light emitting diode display device and ultrasonic fingerprint recognition device thereof

The present invention relates to a fingerprint recognition technology, and in particular to an organic light emitting diode display device and an ultrasonic fingerprint recognition device thereof.

The fingerprint recognition device is installed in the display device because of its privacy protection function. The fingerprint recognition element can recognize the fingerprint of the finger placed on the fingerprint recognition element. When the user places his finger on the surface of the fingerprint recognition element, the fingerprint of the user's finger will be recognized, and then the user's identity information will be verified to enhance the user experience.

Fingerprint recognition electronic products use thin film transistor glass (TFT glass) as the switch for image control. The integrated circuit uses a flexible printed circuit board and thin film transistor to perform a flexible circuit substrate-glass bonding process (FPC on glass, FOG). The piezoelectric conversion unit of the fingerprint recognition device uses wet printing on its thin film transistor glass to complete the copolymer (CP) layer, silver electrode layer and chip adhesive film (DAF, Die Attach Film). The fingerprint recognition sensor and the organic light-emitting diode display module are soft-to-hard (STH) and hard-to-hard (HTH) to complete the entire under-screen fingerprint recognition device. The main cost of fingerprint recognition sensors lies in the glass substrate of thin film transistor pixels, polyvinylidene fluoride (PVDF) layer or copolymer layer, chip bonding film, silver electrode layer and integrated circuit on flexible printed circuit board. The silver electrode layer and chip bonding film mainly use screen printing process to simplify the process cost, but the image will be affected by foreign objects such as pores or impurities in the film layer to the acoustic image signal. However, through the evolution process of existing ultrasonic stacking, many film layers have simplified the interference of signals, but the printed electrode layer cannot be omitted in its stacking.

Therefore, the present invention aims at the above-mentioned troubles and proposes an organic light emitting diode display device and an ultrasonic fingerprint recognition device thereof to solve the problems generated by the prior art.

The present invention provides an organic light emitting diode display device and an ultrasonic fingerprint recognition device thereof, which can omit the existing silver electrode layer and die attach film (DAF) to avoid affecting the image signal of the acoustic transmission.

In one embodiment of the present invention, an ultrasonic fingerprint recognition device includes a transparent substrate, a control circuit layer, multiple sets of electrodes and a hydrophobic insulating piezoelectric layer. The control circuit layer is disposed on the transparent substrate, and the multiple sets of electrodes are disposed on the control circuit layer and are separated from each other.

In one embodiment of the present invention, the control circuit layer includes a first field effect transistor, a second field effect transistor, a third field effect transistor, a diode and a fourth field effect transistor. The first field effect transistor is connected between a first bias terminal and an anode block, and the second field effect transistor and the third field effect transistor are connected between the second bias terminal and a data line.

The fourth field effect transistor is connected between a reset voltage terminal and a data line, wherein the data line and the control terminals of the first field effect transistor, the third field effect transistor and the fourth field effect transistor are connected to an access integrated circuit.

In one embodiment of the present invention, an organic light-emitting diode display device includes a transparent substrate, a control circuit layer, multiple groups of electrodes, a hydrophobic insulating piezoelectric layer, a double-sided adhesive layer, and an organic light-emitting diode display module. The control circuit layer is arranged at the bottom of the transparent substrate, and the multiple groups of electrodes are arranged at the bottom of the control circuit layer and are separated from each other. Each group of electrodes includes an anode block and a cathode block, and the anode block and its corresponding cathode block are arranged at the bottom of the control circuit layer and are separated from each other.

In order to enable you to have a deeper understanding and knowledge of the structural features and effects achieved by the present invention, we would like to provide a better embodiment diagram and a detailed description as follows:

The embodiments of the present invention will be further explained below in conjunction with the relevant drawings. As much as possible, the same reference numerals in the drawings and the specification represent the same or similar components. In the drawings, the shapes and thicknesses may be exaggerated for the sake of simplicity and convenience. It is understood that the components not specifically shown in the drawings or described in the specification are in the form known to the ordinary skilled person in the relevant technical field. The ordinary skilled person in this field can make various changes and modifications based on the content of the present invention.

When an element is referred to as being "on", it can mean that the element is directly on the other element or that there are other elements between the two. Conversely, when an element is referred to as being "directly on" another element, there cannot be other elements between the two. As used herein, the term "and/or" includes any combination of one or more of the listed associated items.

The description of "one embodiment" or "an embodiment" below refers to a specific component, structure or feature associated with at least one embodiment. Therefore, multiple descriptions of "one embodiment" or "an embodiment" appearing in multiple places below are not directed to the same embodiment. Furthermore, specific components, structures and features in one or more embodiments can be combined in an appropriate manner.

The disclosure is particularly described with the following examples, which are used for illustration only, because for those skilled in the art, various changes and modifications can be made without departing from the spirit and scope of the disclosure, so the protection scope of the disclosure shall be determined by the scope of the attached patent application. Throughout the specification and the patent application, unless the content clearly specifies otherwise, the meaning of "one" and "the" includes such a description including "one or at least one" of the element or component. In addition, as used in the disclosure, unless it is clear from the specific context that the plurality is excluded, the singular article also includes the description of plural elements or components. Moreover, when applied in this description and the entire patent application below, unless the content clearly specifies otherwise, the meaning of "in which" may include "in which" and "on which". The terms used throughout the specification and the patent application generally have the ordinary meaning of each term used in the field, in the context of this disclosure, and in the specific context, unless otherwise noted. Certain terms used to describe the present disclosure will be discussed below or elsewhere in this specification to provide practitioners with additional guidance on the description of the present disclosure. Examples anywhere throughout the specification, including the use of examples of any term discussed herein, are used for illustrative purposes only and certainly do not limit the scope and meaning of the present disclosure or any exemplified term.

In addition, if the transmission and provision of electrical signals are described, those familiar with this technology should understand that the transmission process of electrical signals may be accompanied by attenuation or other non-ideal changes, but if the source and receiving end of the transmission or provision of electrical signals are not specifically described, they should be regarded as the same signal in essence. For example, if an electrical signal S is transmitted (or provided) from terminal A of an electronic circuit to terminal B of the electronic circuit, a voltage drop may be generated through the source and drain terminals of a transistor switch and/or possible stray capacitance. However, if the purpose of this design is not to intentionally use the attenuation or other non-ideal changes generated during transmission (or provision) to achieve certain specific technical effects, the electrical signal S at terminals A and B of the electronic circuit should be considered to be essentially the same signal.

In other embodiments, these features, components, or steps may not be required.

An organic light emitting diode display device and an ultrasonic fingerprint recognition device thereof are proposed below. The hydrophobic insulating piezoelectric layer is used as the insulating protective layer of the electronic components, so the chip bonding film can be omitted, and the anode block and the cathode block are used to replace the existing silver electrode layer to avoid affecting the image signal of the acoustic transmission.

FIG. 1 is a structural three-dimensional diagram of an ultrasonic fingerprint recognition device according to an embodiment of the present invention, and FIG. 2 is a structural top view of an ultrasonic fingerprint recognition device according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2, the ultrasonic fingerprint recognition device 1 comprises a transparent substrate 10, a control circuit layer 11, a plurality of sets of electrodes 12, and a hydrophobic insulating piezoelectric layer 13. The material of the hydrophobic insulating piezoelectric layer 13 may be a copolymer. Preferably, the transparent substrate 10 may be, but is not limited to, a glass substrate. The control circuit layer 11 is disposed on the transparent substrate 10, and the plurality of sets of electrodes 12 are disposed on the control circuit layer 11 and are separated from each other. Each set of electrodes 12 includes an anode block 120 and a cathode block 121. Preferably, the material of the anode block 120 and the cathode block 121 is indium tin oxide, but the present invention is not limited thereto. The anode block 120 and the cathode block 121 can be coplanar or non-coplanar. The anode block 120 and its corresponding cathode block 121 are arranged on the control circuit layer 11 and are separated from each other. In one embodiment of the present invention, the anode blocks 120 and the cathode blocks 121 of multiple sets of electrodes 12 can be arranged periodically. In another embodiment, the anode blocks 120 and cathode blocks 121 of the plurality of electrode groups 12 are arranged alternately. The present invention has no limitation on the size and arrangement of the anode blocks 120 and cathode blocks 121. The hydrophobic insulating piezoelectric layer 13 is disposed on the anode blocks 120 and cathode blocks 121 of the plurality of electrode groups 12. The hydrophobic insulating piezoelectric layer 13 can be printed on the same plane to ensure that it has a uniform thickness. There can be a gap between the anode block 120 and its corresponding cathode block 121 or it can be filled with insulating material. Alternatively, the hydrophobic insulating piezoelectric layer 13 is formed between the anode block 120 and its corresponding cathode block 121. For convenience and clarity, in this embodiment, a gap is shown between the anode block 120 and its corresponding cathode block 121. The hydrophobic insulating piezoelectric layer 13 serves as an insulating protective layer for electronic components, so the chip bonding film (DAF) can be omitted, and the anode block 120 and the cathode block 121 are used to replace the existing silver electrode layer to avoid affecting the image signal of the acoustic transmission. The hydrophobic insulating piezoelectric layer 13 and the plurality of electrodes 12 can form a capacitor structure arranged in parallel, namely a lateral capacitor located at the virtual frame position.

When a voltage is applied to the anode block 120 and its corresponding cathode block 121 through a gate line, an electric dipole moment and an electric field in the y direction can be formed, thereby cooperating with the piezoelectric strain constant of the hydrophobic insulating piezoelectric layer 13 to form a deformation in the z direction. If a high-frequency alternating voltage is applied to the anode block 120 and its corresponding cathode block 121, an ultrasonic wave in the z direction will be generated to form a stationary wave. If the ultrasound hits the crests and troughs of the fingerprint, strong and weak rebounds are formed. After being transmitted back to the hydrophobic insulating piezoelectric layer 13, it will cause its deformation and perform positive piezoelectric conversion, so as to generate a difference in voltage level on the anode block 120 and its corresponding cathode block 121, thereby describing the spectrum of the crests and troughs of the fingerprint. In other words, if the hydrophobic insulating piezoelectric layer 13 is deformed in the z direction by applying force with the fingertips, thereby cooperating with the piezoelectric strain constant of the hydrophobic insulating piezoelectric layer 13, the deformation is converted into the electric dipole moment and electric field in the y direction by positive piezoelectric conversion, so as to record the ridge characteristics on the fingertips.

FIG. 3 is an equivalent circuit diagram of a control circuit layer of an embodiment of the present invention. Referring to FIG. 2 and FIG. 3, in some embodiments of the present invention, the control circuit layer 11 may include a first field effect transistor 111, a second field effect transistor 112, a third field effect transistor 113, a fourth field effect transistor 114, a diode 115 and a data line 116. The first field effect transistor 111 is connected between a first bias terminal B1 and an anode block 120, and the second field effect transistor 112 and the third field effect transistor 113 are connected between a second bias terminal B2 and the data line 116. The anode of the diode 115 is connected to the first bias terminal B1, and the cathode is connected to the anode block 120. The fourth field effect transistor 114 is connected between a reset voltage terminal R and the data line 116, wherein the data line 116 and the control terminals of the first field effect transistor 111, the third field effect transistor 113 and the fourth field effect transistor 114 are connected to an access integrated circuit 2. The hydrophobic insulating piezoelectric layer 13, the anode block 120 and the corresponding cathode block 121 form a parasitic capacitor C.

FIG. 4 is a cross-sectional view of the structure of an organic light emitting diode display device of an embodiment of the present invention. Referring to FIG. 4 and FIG. 2, the organic light emitting diode display device is described below, which includes a transparent substrate 10, a control circuit layer 11, a plurality of electrodes 12, a hydrophobic insulating piezoelectric layer 13, a double-sided adhesive layer 14 and an organic light emitting diode display module 15. The control circuit layer 11 is disposed at the bottom of the transparent substrate 10, and the plurality of electrodes 12 are disposed at the bottom of the control circuit layer 10 and are spaced apart from each other. Each set of electrodes 12 includes an anode block 120 and a cathode block 121. The anode block 120 and its corresponding cathode block 121 are disposed at the bottom of the control circuit layer 11 and are separated from each other. The hydrophobic insulating piezoelectric layer 13 is disposed at the bottom of the anode block 120 and the cathode block 121 of the plurality of sets of electrodes 12. The double-sided adhesive layer 14 is disposed on the top of the transparent substrate 10, and the organic light-emitting diode display module 15 is disposed on the top of the double-sided adhesive layer 14. The transparent substrate 10, the control circuit layer 11, the plurality of electrodes 12 and the hydrophobic insulating piezoelectric layer 13 are the ultrasonic fingerprint recognition device mentioned above, which will not be described in detail here. The feasibility of the ultrasonic fingerprint recognition device is explained below in conjunction with the operation of the control circuit layer 11. When in use, the fingertip 3 can be attached to the top of the organic light-emitting diode display module 15.

FIG. 5 is a schematic diagram of the operation of the control circuit layer of an embodiment of the present invention for reverse piezoelectric conversion. Please refer to FIG. 5 and FIG. 4. When the voltage of the first bias terminal B1 is 4 volts and the voltage of the cathode block 121 is 0 volts, the access integrated circuit 2 can turn on the first field effect transistor 111, so that the first bias terminal B1 drives the current to pass through the first field effect transistor 111 to be injected into the anode block 120, and the hydrophobic insulating piezoelectric layer 13 is deformed according to the voltage change of the anode block 120 to complete the reverse piezoelectric conversion. Because the resistance of the first field effect transistor 111 is lower than the resistance of the diode 115 when it is turned on, no current flows through the diode 115 at this time.

FIG6 is a schematic diagram of the operation of the control circuit layer of an embodiment of the present invention when discharging the anode block. Referring to FIG6, when the voltage of the first bias terminal B1 is 4 volts and the cathode block 121 generates an alternating sine wave voltage due to positive voltage conversion, the voltage of the cathode block 121 may be the peak voltage or the valley voltage of the sine wave voltage. When the voltage of the cathode block 121 is a peak voltage, the anode block 120 couples a high voltage, and the access integrated circuit 2 turns on the first field effect transistor 111, so that the anode block 120 discharges the first bias terminal B1, and the voltage of the anode block 120 approaches 4 volts.

FIG. 7 is a schematic diagram of the operation of the control circuit layer of one embodiment of the present invention when charging the anode block. Referring to FIG. 7, when the voltage of the first bias terminal B1 is 4 volts and the voltage of the cathode block 121 is the valley voltage, the anode block 120 is coupled with a low voltage, and the access integrated circuit 2 turns off the first field effect transistor 111, so that the first bias terminal B1 charges the anode block 120, and the voltage of the anode block 120 approaches 4 volts. According to the mechanism of FIG. 6 and FIG. 7, it is possible to prevent the access integrated circuit 2 from receiving unwanted signals.

FIG. 8 is a schematic diagram of the operation of the control circuit layer of one embodiment of the present invention providing a bright signal, FIG. 9 is a schematic diagram of the operation of the control circuit layer of one embodiment of the present invention providing a dark signal, and FIG. 10 is a comparative waveform diagram of the sine wave voltage of the anode block of one embodiment of the present invention. Please refer to FIG. 8 and FIG. 10. When the voltage of the cathode block 121 is zero and positive voltage conversion occurs, a sine wave voltage will appear in the anode block 120, as shown in FIG. 10. Assume that the access integrated circuit 2 turns off the first field effect transistor 111, the third field effect transistor 113 and the fourth field effect transistor 114, and the voltage of the first bias terminal B1 is represented by Dbias. When the sine wave voltage of the anode block 120 is greater than the voltage Dbias, the diode 115 cannot be turned on, and the second field effect transistor 112 will be turned on, so that the second bias terminal B2 provides a current to pass through the second field effect transistor 112 to form a bright signal. Please refer to Figures 9 and 10. When the sine wave voltage of the anode block 120 is less than the voltage Dbias, the diode 115 is turned on, so that the voltage of the anode block 120 is limited to the voltage Dbias, and the second field effect transistor 112 will be turned off, so that the second bias terminal B2 cannot provide a current to pass through the second field effect transistor 112 to form a dark signal. That is, the diode 115 can be used as a peak detector, and only the first half cycle of the sine wave voltage of the anode block 120 will be transmitted to the access integrated circuit 2, and the second half cycle of the signal will be filtered out. Because the access integrated circuit 2 turns off the first field effect transistor 111, the third field effect transistor 113 and the fourth field effect transistor 114, the second field effect transistor 112 can maintain the voltage level to store the charge to confirm that the grayscale signal of the fingerprint spectrum is stable.

FIG. 11 is a schematic diagram of the operation of the control circuit layer outputting signals to the access integrated circuit of one embodiment of the present invention. Referring to FIG. 11, when the access integrated circuit 2 turns off the first field effect transistor 111 and the fourth field effect transistor 114, and turns on the third field effect transistor 113, the bright and dark signals can be output to the access integrated circuit 2 through the second field effect transistor 112, the third field effect transistor 113 and the data line 116 to store the fingerprint spectrum.

According to the above embodiments, the organic light emitting diode display device and the ultrasonic fingerprint recognition device thereof use the hydrophobic insulating piezoelectric layer as the insulating protective layer of the electronic components, so the chip bonding film can be omitted, and the anode block and the cathode block are used to replace the existing silver electrode layer to avoid affecting the image signal of the acoustic transmission.

The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Therefore, all equivalent changes and modifications based on the shape, structure, features and spirit described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
