The operating configuration information can be stored in the storage unit of the device, such as the memory of a mobile phone, the hard disk of a computer, or in the storage unit of the server. When you need to obtain the operating configuration information, just let the device and the server create Communication connection, and then obtain the pre-stored operation configuration information from the server, the communication connection includes Wired communication connection or wireless communication connection.

Preferably, the shape of the sensing unit is a rectangle, and the size of the rectangle is located at the center of the display unit to ensure that the eyeball and imaging are not shifted. Optical axis. This can ensure that as long as the user's eyes are aligned with the display unit, no matter how the user's eyeball is moving, the sensor unit can accurately and quickly collect the user's iris information.

Then go to step S103 to determine whether the captured iris information matches the preset iris information in the operation configuration information, if so, go to step S104 to execute the operation instruction corresponding to the iris information, otherwise go to step S105 to not execute the operation instruction.

Please refer to FIG. 2, which is a flowchart of a method for iris recognition according to another embodiment of the present invention. The step of "presetting the operation configuration information" includes: first entering step S201 to receive a user setting command, and displaying the iris recognition area.

As shown in FIG. 6, in this embodiment, the sensing unit includes a TFT image sensing array film, and the infrared sensing layer includes an array formed by infrared photosensitive diodes. Existing liquid crystal display (LCD) panels or organic light emitting diode (OLED) display panels all use a TFT structure to drive and scan a single picture element to realize the display function of the picture element array on the panel. The main structure forming the switching function of TFT is a metal oxide semiconductor field effect transistor (MOSFET). The well-known semiconductor layer materials are mainly amorphous silicon, polysilicon, indium gallium zinc oxide (IGZO), or mixed with carbon nanomaterials. Organic compounds and so on. Since the structure of the photo-sensing diode can also be made of such semiconductor materials, and the production equipment is also compatible with the production equipment of the TFT array, in recent years, the TFT photo-detecting diode has begun to be produced by the TFT array preparation method. The TFT image sensor array film described in this embodiment is the aforementioned TFT photodetection diode (the part of the photodetection diode area in FIG. 6). For the specific structure, please refer to US Pat. No. 6,943,070B2, China The description of the structure of the sensing unit in the People's Republic of Patent CN204808361U. The production process of the TFT image sensing array film is different from the TFT structure of the display panel in that the original opening area of the picture element of the display panel is changed to the light sensing area in the production process. The TFT preparation method can use thin glass as the substrate, or use high-temperature resistant plastic material as the substrate, as described in US Patent No. 6,943,070 B2.

The sensor unit shown in Figure 6 is easily affected by the surrounding ambient light or the reflection and refraction of visible light emitted by the display screen pixels, causing optical interference and serious impact. In response to the signal-to-noise ratio (SNR) of the TFT image sensor array film embedded under the display panel, in order to improve the signal-to-noise ratio, the sensor unit of the present invention is based on the sensor unit shown in FIG. 6 A further improvement allows the TFT image sensor array film to detect and identify the infrared signal reflected by the iris of the user’s eyeball.

As shown in FIG. 7, in some embodiments, the infrared sensing layer is an array formed by infrared photosensitive diodes. In order to expand the wavelength of the light signal that can be recognized by the TFT image sensor array film from the visible light range to the infrared light range, the TFT image sensor array film in Figure 6 is improved, specifically by replacing the TFT image in Figure 6 with an infrared photosensitive diode The photodiode layer of the sensing array film, the infrared photodiode includes a microcrystalline silicon photodiode or an amorphous silicon photodiode.

Embodiment 1: The amorphous silicon p-type/i-type/n-type photodiode structure (photodiode layer in FIG. 6) is changed to a microcrystalline silicon p-type/i-type/n-type photodiode structure. In this embodiment, the degree of microcrystallinity of the photodiode is mainly in the chemical meteorological deposition process, mixed with gas silane (SiH4) with appropriate hydrogen concentration to control the dangling bond of hydrogen atoms to bond amorphous silicon. To realize the coating of microcrystalline silicon p-type/i-type/n-type photodiode structure. By adjusting the hydrogen concentration of chemical weather deposition, the operating wavelength range of the microcrystalline photodiode can be extended to the light wavelength range of 600nm to 1000nm.

In the embodiment using the microcrystalline photodiode, in order to further improve the quantum efficiency of photoelectric conversion, the microcrystalline silicon photodiode can also be formed in series with a p-type/i-type/n-type structure above the double junction. The p-type/i-type/n-type material of the first junction layer of the photodiode still has an amorphous structure, and the p-type/i-type/n-type material above the second junction layer may be microcrystalline Structure, polycrystalline structure.

Example 2: Change the amorphous silicon p-type/i-type/n-type photodiode structure (photodiode layer in Figure 6) to p-type/i-type doped with an amorphous silicon compound that can extend the photosensitive wavelength range /n-type photodiode structure, a preferred example of the compound is amorphous germanium silicide. In this embodiment, the essential layer (i-type) of the photodiode is deposited in the chemical weather deposition process, the gas germane (GeH4) is mixed with silane (SiH4) to realize the amorphous germanium silicide p-type/i The photosensitive range of the type/n-type photodiode reaches the range of light wavelength from 600nm to 1000nm.

In the embodiment using the amorphous silicon compound photodiode, in order to improve the quantum efficiency of photoelectric conversion, the amorphous silicon photodiode can also be formed in series with a p-type/i-type/n-type structure above the double junction. The p-type/i-type/n-type material of the first junction layer of the photodiode still has an amorphous silicon structure, and the p-type/i-type/n-type material above the second junction layer may have a microcrystalline structure, a polycrystalline structure or Doped with compound materials that can extend the photosensitive wavelength range.

When the infrared sensing layer is an array formed by infrared photosensitive diodes, in the actual application process, a bias voltage (including forward bias, or zero bias or negative bias) can be applied by TFT for scanning and driving. Between the p-type/i-type/n-type photodiodes, the TFT image sensing array film can emit infrared light. In some embodiments, the first trigger signal can pass through the p-type/i-type/n-type infrared A positive bias voltage is applied between the photosensitive diodes to trigger, and the second trigger signal can be triggered by applying a zero bias voltage or a negative bias voltage between the p-type/i-type/n-type infrared photosensitive diodes. For example, if the array formed by the infrared photosensitive diode has 10 columns (assuming the number is 1-10), then a forward bias can be applied to the odd-numbered pixel point array to make The odd-numbered pixel dot array can emit infrared light signals, and zero or negative bias is applied to the even-numbered pixel dot array, so that the even-numbered pixel dot array is in the state of detecting infrared light to capture and use The infrared light reflected by the iris of the eyeball is converted into an infrared image for output. Of course, in other embodiments, the first trigger signal can be triggered by applying zero bias or negative bias between the p-type/i-type/n-type infrared photosensitive diodes, and the second trigger signal can be triggered by the p-type/i-type/n-type infrared photodiode. /i-type/n-type infrared photosensitive diodes are triggered by applying a forward bias voltage.

In some embodiments, it is also possible to alternately apply a positive bias, or a zero bias or a negative bias between the p-type/i-type/n-type infrared photosensitive diodes to trigger the first trigger signal or The second trigger signal. Similarly, taking the array of infrared photosensitive diodes with 10 rows of pixel lattices as an example, the p-type/i-type/n-type infrared photosensitive diodes are forward biased in the first cycle to make 10 rows of graphs The element lattice is in the state of emitting infrared light; in the second period, zero bias or negative bias is applied to the p-type/i-type/n-type infrared photosensitive diode, so that the 10 columns of picture element lattices are all in the infrared light detection Measuring state, used to capture the infrared light information reflected by the iris of the user’s eyeball, and generate the corresponding infrared image output; in the third period, the p-type/i-type/n-type infrared photosensitive diode is forward biased Press to make the 10 columns of image element lattices are in the state of emitting infrared light, alternately repeatedly, and so on. The time interval between adjacent cycles can be set according to actual needs, and the preferred time interval can be set to the TFT array driving scan every frame (Frame) infrared photosensitive diode array can receive at least one frame of complete image signal time.

In some embodiments, the operation instruction is a screen switching instruction; the step "determine whether the preset iris information in the captured iris information and the operation configuration information is Match, if yes, execute the operation instruction corresponding to the iris information, otherwise do not execute the operation instruction" includes: judging whether the captured iris information matches the iris information corresponding to the screen switching instruction, if so, the screen is switched, otherwise the screen is not Switching. Since the video stream data is composed of one frame of images, the method of this embodiment is also applicable to the judgment of the video stream data.

In some embodiments, the operation instruction is a payment instruction; the step "determine whether the captured iris information matches the preset iris information in the operation configuration information, if so, execute the operation instruction corresponding to the iris information, otherwise it will not execute The "operation instruction" includes: determining whether the captured iris information matches the iris information corresponding to the payment instruction, if so, the payment is successful, otherwise the payment fails. Linking the payment instruction with the user's iris information identification can effectively enhance the security of transaction payment, and at the same time prevent other users from causing unnecessary losses to the head of the household due to misoperation.
