Description

Calibration method of electronic device including packaging box and fingerprint sensor thereof

Various embodiments relate to an electronic device including a packaging box and a fingerprint sensor recognition method thereof.

Calibration is one of the processes performed during the production and assembly of electronic components assembled in an electronic device, and may be performed to equalize component performance, detect defective components, and/or optimize performance.

As part of strengthening security, electronic devices provide a function to authenticate the user using the user's biometric information (e.g., fingerprint, iris). For example, the fingerprint recognition function is the most widely used technology in biometric authentication, and with the recent release of electronic devices in the form of full front screens that use the entire front as a display, optical fingerprint sensors (( Example: There is a trend to equip electronic devices with FOD (fingerprint on display) or in-display fingerprint (FOD)).

An optical fingerprint sensor can detect a fingerprint by receiving reflected light generated by an external object (e.g., a user's finger) and generating and processing an image based on the reflected light. However, when the optical fingerprint sensor is located at the bottom of the display, the optical fingerprint sensor receives reflected light that is reflected while passing through a material that distorts the subject, such as glass or a display. Due to these characteristics, the image obtained from the optical fingerprint sensor is distorted, so the fingerprint sensor is calibrated.

In this way, an electronic device including an optical fingerprint sensor improves recognition performance by improving the image quality distorted by the display, and at the same time performs a calibration process to check for defects by correcting the display characteristic deviation and the fingerprint sensor unit. You can proceed.

Calibration of the fingerprint sensor is performed during the manufacturing process of the electronic device, but an environment may arise in which calibration must be performed again during the user's use of the electronic device. For example, if the display or fingerprint sensor is replaced, if the display characteristics change (e.g. light source brightness changes or display deterioration), or if the user wants to recheck the performance of the fingerprint sensor, calibration may need to be performed again. There is a need.

Generally, if a problem occurs with the fingerprint sensor performance, the user must visit the electronic device manufacturer's repair shop directly to replace parts (e.g. display or fingerprint recognition sensor) and then re-calibrate the fingerprint sensor through the repair shop. It may cause inconvenience.

Alternatively, in order for the user to directly calibrate the fingerprint sensor, an additional calibration kit or tool for a separate calibration environment is required, and a surrounding environment for calibration must be created. However, even if the user uses a separate calibration kit or tool, it is not only difficult to create an environment suitable for the calibration process, but also the values or images generated through incorrect calibration affect the performance of the fingerprint sensor, reducing recognition performance. It can deteriorate.

In addition, even though there is no actual problem, if calibration fails due to the influence of an incorrect external environment, it may be mistaken for a defective part.

The technical problem to be achieved in the present disclosure is not limited to the technical problem mentioned above, and other technical problems not mentioned can be clearly understood by those skilled in the art from the description below. There will be.

An electronic device according to an embodiment may include a display, a fingerprint sensor, and a processor.

The processor according to one embodiment may be set to output result information depending on whether calibration of the fingerprint sensor is successful or not as an audio signal or display it on a display.

Hereinafter, specific operations for step-by-step calibration of the fingerprint sensor are shown in FIG. 5. Let me explain.

FIG. 3A shows the external appearance of an electronic device packaging box according to one embodiment, and FIG. 3B shows a cross-sectional view of the electronic device packaging box. Figure 4 shows an example of the shape of a three-dimensional tool according to one embodiment.

Referring to FIGS. 3A and 3B, the packaging box 301 of an electronic device (e.g., the electronic device 101 of FIG. 1) according to one embodiment includes a lower case that forms a space for accommodating the electronic device and electronic device accessories. It may include (310), an upper case (320) covering the open upper part of the lower case (310), and an intermediate support (330).

The packaging box 301 of the electronic device 101 is manufactured to package the main product and accessories (e.g., charger, cable, earphone, and user manual) of the electronic device 101, and may be distributed as a packaging box.

According to one embodiment, the upper case 320 may be formed to have a predetermined width larger than the outer area of the lower case 310 and may be configured to surround the side of the lower case 310 where the upper part is open.

According to one embodiment, the middle support 330 may separate the internal space created by combining the lower case 310 and the upper case 320 into two spaces (eg, upper/lower). For example, the packaging box 301 stores the electronic device 101 in a first space based on the intermediate support 330, and accessories provided in addition to the electronic device 101 (e.g., charger, cable) are stored in the second space. , earphones, and user manual) can be manufactured.

According to one embodiment, the packaging box 301 guides the electronic device to be seated in a fixed position on the upper surface of the middle support 330 (e.g., z-direction) or the upper surface of the lower case 310 (e.g., z-direction). It may include a first side support 370 and/or a second side support 380.

According to one embodiment, the first side wall support 370 prevents the electronic device 101 from moving up, down, left, or right when the electronic device 101 is placed on the upper surface (e.g., z-direction) of the middle support 330. Since the position can be fixed to prevent the electronic device 101 from shaking or changing its position, a stable calibration environment can be created.

According to one embodiment, the second side wall support 380 fixes the position of the electronic device 101 when the electronic device 101 is seated on the upper surface (e.g., z-direction) of the lower case 310, thereby It is possible to create a stable calibration environment by preventing shaking or change in position of the device 101.

The packaging box 301 of the electronic device 101 according to one embodiment may include tools for calibrating the fingerprint sensor, as shown in FIG. 3B.

For example, the tools include at least a first tool 340 for reflection (white calibration), a second tool 350 for absorption (black calibration), or a third tool 360 for pattern photography (stereoscopic calibration (or 3D calibration)). It can contain one.

According to one embodiment, the first tool 340, the second tool 350, and the third tool 360 are located in the space between the lower case 310 and the intermediate support 330 (e.g., the first space (a) ), the space between the upper case 320 and the middle support 330 (e.g., the second space (b)), at least a part of the middle support 330, or at least a part of the space of the lower case 310, It can be placed in a location. The arrangement structure shown in FIG. 3B is only an example and is not limited thereto. For example, the positions of the first tool 340, the second tool 350, and the third tool 360 may be changed. For example, at least one of the first tool 340, the second tool 350, and the third tool 360 may be omitted.

According to one embodiment, the first tool 340 may include a flat reflective surface 340a to perform white calibration. For example, the first tool 340 may include a highly reflective colored material such as skin color, pink, or white. For example, the first tool 340 may include at least one of rubber, silicone, paper, cloth, or plastic, but is not limited thereto. The first tool 340 is arranged to cover the display area used as the fingerprint sensor 220 and the light source 215 by reflecting the light emitted from the light source 215 to the top of the display and making it enter the fingerprint sensor 220. It can be. For example, the first tool 340 may have a rectangular parallelepiped shape with one side open.

According to one embodiment, the second tool 350 may include a flat absorption surface 350a to perform black calibration. For example, the second tool 350 may include a material with a low reflectance color, such as gray or black. For example, the second tool 350 may include at least one of rubber, silicone, paper, cloth, or plastic, but is not limited thereto. The purpose of the second tool 350 is to absorb the light emitted from the light source 215 to prevent the light that exits the top of the display from entering the fingerprint sensor again, and to allow only the light that exits the bottom to enter the fingerprint sensor 220. It can be arranged in a size that covers the display area used by the sensor 220 and the light source 215. For example, the second tool 350 may have a rectangular parallelepiped shape with one side open.

According to one embodiment, the third tool 360 performs three-dimensional calibration, unlike the flat surfaces (e.g., the reflecting surface 340a and the absorbing surface 350a) of the first tool 340 and the second tool 350. In order to do this, a three-dimensional pattern surface 360a including curves may be included. For example, the third tool 360 may include a material that can adhere to the fingerprint sensor 220 by a certain pressure (eg, the effect of finger pressure).

For example, the third tool 360 may have a shape including a curved shape by etching rubber or silicon in an engraved form, as shown in <401> of FIG. 4 . For example, the third tool 360, as shown in <402> of FIG. 4, has a shape of a printed pattern drawn on a paper material 362 with a thickness to which a certain pressure can be applied together with the reinforcing material 361. You can. The three-dimensional pattern formed on the third tool 360 may have various shapes and corresponds to well-known technology, so detailed description will be omitted. In one embodiment, the third tool 360 covers the display area used as the fingerprint sensor 220 and the light source 215 by reflecting or absorbing the light emitted from the light source 215 and incident on the fingerprint sensor 220. It can be arranged in any size.

Although not shown in the drawing, in one embodiment, guidance text related to the fingerprint sensor calibration procedure may be printed on the packaging box close to the area where each tool is placed. When performing fingerprint sensor calibration, the user can check the position or posture of placing the electronic device in the packaging box through the guidance text.

FIG. 5 illustrates a fingerprint sensor calibration method using a packaging box of an electronic device according to an embodiment. Each operation shown in FIG. 5 may be performed sequentially, but is not necessarily performed sequentially, and the order of each operation may be changed or at least some of the operations may be omitted.

Referring to FIG. 5, according to one embodiment, the processor of the electronic device (e.g., processor 120 of FIGS. 1 and 2) (or fingerprint sensor calibration module (e.g., fingerprint sensor calibration module 230 of FIG. 2)) In operation 510, a user guide user interface (UI) for the calibration procedure of the fingerprint sensor is displayed (e.g., the display of FIG. 2) based on the calibration requirement of the fingerprint sensor (e.g., the fingerprint sensor 220 of FIG. 2) being detected. (210)).

For example, the processor 120 monitors electronic components (e.g., display, fingerprint sensor, or main board) associated with the operation of the fingerprint sensor to detect defects in the electronic components, or when a specified replacement period is reached, the fingerprint sensor It can be recognized that a calibration requirement has been detected. For example, the processor 120 detects a decrease in recognition performance related to the fingerprint sensor operation based on an internal standard set in relation to the electronic component, or detects a decrease in the fingerprint sensor performance by attaching (or replacing) a protective film on the display 210. If environmental factors affecting the sensor are detected, the fingerprint sensor calibration requirement can be recognized as detected.

According to some embodiments, the processor 120 may recognize that a fingerprint sensor calibration requirement has been detected when a user input entered into the fingerprint sensor calibration progress menu is detected.

According to one embodiment, the processor 120 may display the user guide UI in a pop-up form or in a notification window. The user guide UI may include text and a start item (or start menu) for a description of the fingerprint sensor method.

When the user selects a startup item, the user can perform self-fingerprint sensor calibration.

In operation 515, the processor 120 may output a first guidance voice for white calibration (e.g., audio such as “Please place the electronic device at the location for the first stage calibration in the packaging box”).

According to one embodiment, the user aligns the first area in the packaging box 301 where the first tool (e.g., 340 in FIG. 3B) is placed with the light source of the fingerprint sensor (e.g., the display area where the fingerprint sensor is placed). The electronic device 101 may be placed in the packaging box 301 and the upper case (e.g., 320 in FIG. 3B) and the lower case (e.g., 310 in FIG. 3B) may be coupled so that they are aligned to face each other. As the upper case 320 and lower case 310 are combined, a calibration environment can be created inside the packaging box 301.

In operation 520, the processor 120 may perform white calibration (or first-stage calibration) based on a set time elapsed after the first guidance voice is output or when an input such as a “start” voice is detected from an external source. For example, the processor 120 emits a light source and receives the reflected light reflected through the first tool 340 through the fingerprint sensor 220, and measures the amount of light received (or brightness value) of the fingerprint sensor 220. You can. The processor 120 may generate first correction data or check optical characteristics (eg, exposure time) based on the measured amount of received light.

In operation 525, the processor 120 may determine whether white calibration is successful depending on whether the reflected light reflected through the first tool 340 falls within a set range of the fingerprint sensor 220. If the white calibration fails, the processor 120 proceeds to operation 530 and compares whether the number of white calibration attempts is the set N times in order to attempt white calibration a set number of times. As a result of comparison, if the number of white calibration attempts is lower than N (e.g. pass), proceed with operation 520, and if the number of white calibration attempts exceeds N but fail (e.g. fail), proceed with operation 585. there is.

If the white calibration is successful, the processor 120 sends a second guidance voice (e.g., “Please place the electronic device in the location for black calibration within the packaging box”) to perform black calibration (or second-level calibration) in operation 535. audio such as ” can be output. For example, the user may view the second area in the packaging box 301 where the second tool 350 is placed and the light source of the fingerprint sensor 220 (e.g., the display area where the fingerprint sensor is placed) 215 facing each other. The electronic device 101 may be placed in the packaging box 301 and the upper case 320 and lower case 310 may be coupled to each other so that the electronic device 101 is aligned.

In operation 540, the processor 120 may perform black calibration based on a set time elapsed after output of the second guidance voice or when an input such as a “start” voice is detected from an external source. For example, the processor 120 emits light from the light source 215 and receives light from the fingerprint sensor 350 through the second tool 350, and uses the background image or amount of light received (or brightness) from the fingerprint sensor 350. value) can be measured. The processor 120 may generate second correction data or acquire a background image based on the measured background image or amount of received light, and check noise signal characteristics.

In operation 545, the processor 120 may determine whether black calibration is successful based on whether the amount of light or image received based on the second tool 350 falls within a set range of the fingerprint sensor 220. If black calibration fails, the processor 120 proceeds to operation 550 and compares whether the number of black calibration attempts is the set N times. As a result of comparison, if the number of black calibration attempts is lower than N (e.g. pass), proceed with operation 540, and if the number of black calibration attempts exceeds N but fail (e.g. fail), proceed with operation 585. there is.

If the black calibration is successful, the processor 120 sends a third guidance voice (e.g., “Please place the electronic device in the location for stereoscopic calibration within the packaging box”) to perform stereoscopic calibration (or three-step calibration) in operation 555. audio such as ” can be output. For example, the user may view the third area in the packaging box 301 where the third tool 360 is placed and the light source of the fingerprint sensor 220 (e.g., the display area where the fingerprint sensor is placed) 215 facing each other. The electronic device 101 may be placed in the packaging box 301 and the upper case 320 and lower case 310 may be coupled to each other so that the electronic device 101 is aligned.

In operation 560, the processor 120 may perform stereoscopic calibration based on a set time elapsed after the third guidance voice is output or when an input such as a “start” voice is detected from an external source. For example, the processor 120 emits the light source 215 to receive light received through the third tool 360 through the fingerprint sensor 220 and generates a pattern image based on the received light signal. You can. For example, the processor 120 analyzes the stored curved pattern of the third tool 360 and the pattern image acquired through the fingerprint sensor 220 to generate third correction data or adjusts the resolution, noise, or sharpness, etc. You can check the fingerprint sensor characteristics.

In operation 565, the processor 120 may determine whether stereoscopic calibration is successful depending on whether the quality of the pattern image generated based on the optical signal received by the third tool 360 satisfies a reference value. If the stereoscopic calibration fails, the processor 120 proceeds to operation 570 and compares whether the number of stereoscopic calibration attempts is the set N number in order to attempt the stereoscopic calibration a set number of times. As a result of the comparison, if the number of stereoscopic calibration attempts is lower than N (e.g. pass), proceed with operation 560, and if the number of stereoscopic calibration attempts exceeds N but fail (e.g. fail), proceed with operation 585. there is.

In operation 580, the processor 120 may once again check whether all steps of calibration have been successful, and if all steps of calibration have succeeded, may provide termination guidance.

In operation 585, if

operation

530, 550, 570, or 580 fails, the processor 120 may provide the user with information on the reason for the failure and a guide to inspect tools (e.g., voice guidance). .

In operation 590, when an input for re-calibrating the fingerprint sensor is received by the user, the processor 120 may perform operations 510 to 580.

In operation 595, when the processor 120 does not receive an input for re-proceeding fingerprint sensor calibration, it may output guide information inducing a visit to a service center (or repair shop) as an audio signal or display it on the display.

According to one embodiment, the processor 120 may guide the user to perform only white calibration or black calibration, or may guide the user to perform only three-dimensional calibration, depending on the operating performance of the fingerprint sensor 220 or environmental factors.
