With ever-increasing screen ratios of displays in electronic devices, full-screen devices have become trendy. For a full screen, a sensor (such as a light sensor) previously located on a display may have to be provided under the full screen. Take a photosensitive sensor as an example.

In some applications, a photosensitive sensor may be made of a photosensitive Thin-Film Transistor (TFT) according to a solution of a large-area optical fingerprint under a low-cost Organic Light-Emitting Diode (OLED) screen. A quality fingerprint image may form a basis of fingerprint unlocking interpretation. That is, the better a contrast of a fingerprint image, the better fingerprint unlocking may work.
To acquire a better contrast, a photosensitive sensor may have to be exposed to light for a certain duration. Under normal light, a certain duration of exposure may result in a signal base as shown in part A of
In this case, a sum of the signal base and the signal per se may exceed a dynamic range of a readout integrated circuit (ROIC) of a rear end of the photosensitive sensor. In other words, in case of a higher signal base, a ROIC may truncate a signal and cause signal distortion, decreasing accuracy in detection.
In view of this, some embodiments of the present disclosure provide a light sensor module and a method for acquiring light intensity. A first detection region may be provided on a substrate of a light sensor module according to some embodiments of the present disclosure. At least one photosensitive device may be provided inside the first detection region. That is, with embodiments herein, light sensor data (referred hereinafter as first light sensor data) under current incident light may be acquired using the at least one photosensitive device. It may be determined, using the first light sensor data, whether light sensor data collected by the light sensor module under the current incident light are to be compensated. For example, when the first light sensor data exceed a set threshold, light sensor data collected by the light sensor module may be compensated. When the first light sensor data are no greater than the set threshold, it may not be necessary to compensate the light sensor data collected by the light sensor module. Accordingly, with embodiments herein, light sensor data detected by a light sensor module may match current incident light, avoiding occurrence of an insufficient dynamic range of the ROIC, increasing accuracy in detection.
A specific structure of a light sensor module is introduced below. Referring to
At least one photosensitive device may be provided inside the first detection region 21. The at least one photosensitive device may be adapted to collecting first light sensor data under current incident light. The first light sensor data may be used for determining whether light sensor data collected by the light sensor module under the current incident light are to be compensated.
A number of photosensitive devices may be provided inside the second detection region 22. The photosensitive device may collect second light sensor data under the under current incident light. The second light sensor data may be the light sensor data collected.
Understandably, the second light sensor data may be the light sensor data collected by the light sensor module. The first light sensor data are assist data that assist in determining whether the second light sensor data are to be compensated. The assist data per se may not necessarily be output by the light sensor module.
Consider a scene of application of a light sensor module, such as a fingerprint sensor. With embodiments herein, the first detection region 21 may be provided outside the second detection region 22. In addition, considering time and an amount of computation required to process light sensor data, with embodiments herein, an area of the first detection region may be less than an area of the second detection region, thereby reducing the light sensor data collected by the at least one photosensitive device inside the first detection region. Understandably, the size of the area of the first detection region and of the second detection region may be provided according to a specific scene, which is not limited herein.
With embodiments herein, the first detection region may include at least one sub detection region.
For example, there may be one sub detection region. Refer to
Note that according to the embodiment, by providing a bar region, it may be avoided that a finger of a user covers up the entire first detection region. In application, it may be provided that a length of a bar region is greater than a width of a finger, ensuring that a photosensitive device inside the first detection region may detect incident light. In addition, a bar-shaped first detection region may be manufactured with ease, improving yield.
For example, there may be multiple sub detection regions. Refer to
Note that according to the embodiment, by providing a sub detection region at a vertex, a distance between two sub detection regions on a diagonal may be maximized. Accordingly, it is unlikely that a finger may cover the two sub detection regions simultaneously, ensuring that a photosensitive device inside the first detection region may detect incident light.
Also note that when there are multiple sub detection regions, a solution formed by a combination including a bar sub detection region and a square sub detection region may likewise fall into the scope of the subject disclosure.
With embodiments herein, an area of a photosensitive device inside the first detection region 21 may be greater than an area of a photosensitive device inside the second detection region 22, ensuring an amount of incident light incident on a photosensitive device, reducing a collecting time. According to an example, a photosensitive device may include multiple photosensitive devices. That is, photosensitive devices (such as a TFT) may be made on a substrate using one process. Then, gate lines of the multiple photosensitive devices inside the first detection region 21 may be connected to each other. Data lines of the multiple photosensitive devices may be connected to each other. That is, the multiple photosensitive devices may sense incident light simultaneously and output light sensor data simultaneously. In other words, according to these embodiments, a ratio of an area of a photosensitive device to an area of the photosensitive device may be 1:n. The n may be 4˜9.
Referring again to
To collect new light sensor data, the GOA 40 may turn on each row of photosensitive devices in turn. In this case, a data line may input a set value to a photosensitive device. That is, the photosensitive device may be cleared (or reset). Then, the photosensitive device may sense incident light for a duration (such as 70 ms). The GOA 40 may input a valid signal to each row of gates to turn on each line of photosensitive devices. The ROIC 30 may read light sensor data. Note that a light sensor module made based on a TFT may work according to a principle similar to that of an array substrate made based on a TFT, which is not repeated herein.
Note that when multiple sub detection regions are provided inside the first detection region, the ROIC 30 may read light sensor data in an order. The GOA 40 may provide a number of dedicated pins to be connected to respective sub detection regions. For example, there may be a one-to-one correspondence between the dedicated pins and the sub detection regions. In this case, the ROIC may read light sensor data in each sub detection region sub region by sub region. According to an example, a dedicated pin may correspond to one row of sub detection regions. In this case, the ROIC may read light sensor data in each row of sub detection regions row by row. According to an example, all sub detection regions may be connected to one dedicated pin. In this case, the ROIC may read light sensor data in all rows of sub detection regions simultaneously.
With embodiments herein, a photosensitive device may be provided in the first detection region. A photosensitive device may be provided in the second detection region. Accordingly, the light sensor module may work in a cycle as follows.
First, light sensor data collected by a photosensitive device inside the first detection region may be acquired, in a process as illustrated above. Maximal light sensor data may be taken as the first light sensor data.
Then, light sensor data collected by a photosensitive device inside the second detection region may be acquired, in a process as illustrated above.
That is, according to these embodiments, a frame of light sensor data may be acquired in two parts. A first part to be acquired may be light sensor data corresponding to the first detection region, i.e., the first light sensor data. The second part to be acquired may be light sensor data corresponding to the second detection region, i.e., the second light sensor data. In addition, the first part and the second part may have to be acquired in the fixed order. This is because electronic equipment using the light sensor module may have to determine, according to the first light sensor data, whether the second light sensor data are to be compensated.
First, light sensor data collected by pixels inside the first detection region may be read. Then, light sensor data collected by pixels inside the second detection region may be read. That is, pixels may be enabled respectively in the order of gate lines 0)→1) 2) 3) 4) 5). Light sensor data may be read while all pixels are enabled. Pixels along the gate lines 0) may be enabled first, and then the row 1) of pixels may be enabled, with a variable interval in between. The rows 1)˜5) of pixels may be enabled row by row in a variable order, generally with a fixed interval. Accordingly, readout time may be saved when a large amount of light sensor data are acquired.
When the first detection region includes multiple sub detection regions, light sensor data collected by pixels inside the multiple sub detection regions may be read in an order as follows.
According to some embodiments of the present disclosure, light sensor data collected in respective sub detection regions may be read simultaneously. Then, the second light sensor data inside the second detection region may be read row by row.
According to some embodiments of the present disclosure, first, light sensor data collected by pixels inside multiple sub detection regions located at one row may be read simultaneously or sub region by sub region. Then, light sensor data in multiple sub detection regions at another row may be read. For example, sub detection regions may be provided at four corners. Then, light sensor data in the two sub detection regions at the upper row may be read first. Then, light sensor data in the two sub detection regions at the lower row may be read. After light sensor data in all sub detection regions have been read, light sensor data inside the second detection region may be read row by row.
When multiple sub detection regions are provided, compensation may be performed as long as light sensor data in one of the sub detection regions exceed a set threshold. When light sensor data in multiple sub detection regions exceed the set threshold, the maximal light sensor data (i.e., the first light sensor data) may be set as a compensating value. In some embodiments, light sensor data within a distinct interval may be set to correspond to a compensating value. Then, a compensating value may be input to a compensating circuit, which then may perform compensation.
With embodiments herein, light sensor data may be compensated via hardware. To this end, the light sensor module may further include a compensating circuit provided at a front end of a ROIC. Referring to
The compensating circuit may work as follows.
In a first mode, the compensating circuit may perform compensation using a compensating current source.
Current of a light sensor may be pointed downward. That is, electric charge may move toward the feedback capacitor CF (electric charge may be drawn by the CF). In this case, output voltage Vo may increase by IC*t/CF. The t may denote time during which electric charge continues moving toward the feedback capacitor CF. Accordingly, in this case, the first switch S1 may be switched on to connect the compensating current source. In this case, current of the compensating current source may be −IC*t/CF. That is, compensated voltage Vo′=Vo−Cc/CF*Vc, thereby decreasing light sensor data.
In a second mode, the compensating circuit may perform compensation using the compensating voltage source VC and the compensating capacitor CC.
When a base of a light sensor is overly large and compensation has to be performed, the second switch S2 may be switched on. The feedback capacitor CF may be supplemented with electric charge in a reverse direction by adjusting compensating voltage Vc. In this case, the compensating voltage Vc may produce a change −Cc/CF*Vc in the output of the operational amplifier. That is, compensated voltage Vo′=Vo−Cc/CF*Vc, thereby decreasing light sensor data.
Note that with embodiments herein, it may be set beforehand whether calibration is performed using a voltage compensating circuit or a current compensating circuit. For example, only a voltage compensating circuit may be provided. That is, compensation may be performed only by voltage compensation. In some embodiments, only a current compensating circuit may be provided. That is, compensation may be performed only by current compensation. In some embodiments, a voltage compensating circuit and a current compensating circuit may be provided simultaneously. A trigger condition for triggering current compensation or voltage compensation may be provided beforehand, such as by providing a threshold. When a signal excess exceeds the threshold (i.e., large light sensor data may have to be deducted), the current compensating circuit may be triggered. That is, the current compensating circuit may be triggered by a trigger condition that the first light sensor data exceed the threshold, as a current compensating circuit may calibrate a wide range, i.e., a large signal interval. When a signal excess is no greater than the threshold, the voltage compensating circuit may be triggered, as voltage supplement is more precise when a signal excess is within a small interval.
So far, the specific structure of the light sensor module has been illustrated.
It may be seen that with embodiments herein, light sensor data under current incident light may be collected by at least one photosensitive device inside a first detection region on a substrate. Then, compensating data under the incident light inside a second detection region in a light sensor module may be determined using the light sensor data. Accordingly, light sensor data corresponding to the second detection region in the light sensor module may be compensated according to the compensating data. Compensated light sensor data may be set as final detected light sensor data. With embodiments herein, the amount of light sensor data acquired by a photosensitive device may be far less than the amount of light sensor data acquired by all photosensitive device on the substrate. Processing time may be reduced. Thus, light sensor data acquired subsequently may be compensated according to scenes of different incident light, thereby decreasing a signal base. Accordingly, a sum of a signal base and a signal per se may be made less than a dynamic range of a readout integrated circuit (ROIC), avoiding occurrence of an insufficient dynamic range of the ROIC.
Based on the light sensor module, embodiments herein may further provide a method for acquiring light intensity. The method is applicable to electronic equipment provided with a light sensor module shown in

A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them.
Moreover, while a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially-generated propagated signal. The computer storage medium can also be, or be included in, one or more separate components or media (e.g., multiple CDs, disks, drives, or other storage devices). Accordingly, the computer storage medium can be tangible.
The operations described in this disclosure can be implemented as operations performed by a data processing apparatus on data stored on one or more computer-readable storage devices or received from other sources.
The devices in this disclosure can include special purpose logic circuitry, e.g., an FPGA (field-programmable gate array), or an ASIC (application-specific integrated circuit). The device can also include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, a cross-platform runtime environment, a virtual machine, or a combination of one or more of them. The devices and execution environment can realize various different computing model infrastructures, such as web services, distributed computing, and grid computing infrastructures.
A computer program (also known as a program, software, software application, app, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a portion, component, subroutine, object, or other portion suitable for use in a computing environment. A computer program can, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more portions, sub-programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
The processes and logic flows described in this disclosure can be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA, or an ASIC.
Processors or processing circuits suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory, or a random-access memory, or both. Elements of a computer can include a processor configured to perform actions in accordance with instructions and one or more memory devices for storing instructions and data.
Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), to name just a few.
Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented with a computer and/or a display device, e.g., a VR/AR device, a head-mount display (HMD) device, a head-up display (HUD) device, smart eyewear (e.g., glasses), a CRT (cathode-ray tube), LCD (liquid-crystal display), OLED (organic light emitting diode), or any other monitor for displaying information to the user and a keyboard, a pointing device, e.g., a mouse, trackball, etc., or a touch screen, touch pad, etc., by which the user can provide input to the computer.
Implementations of the subject matter described in this specification can be implemented in a computing system that includes a back-end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front-end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back-end, middleware, or front-end components.
The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).
While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any claims, but rather as descriptions of features specific to particular implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination.
Moreover, although features can be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination can be directed to a subcombination or variation of a subcombination.
Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing can be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
As such, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking or parallel processing can be utilized.
It is intended that the specification and embodiments be considered as examples only. Other embodiments of the disclosure will be apparent to those skilled in the art in view of the specification and drawings of the present disclosure. That is, although specific embodiments have been described above in detail, the description is merely for purposes of illustration. It should be appreciated, therefore, that many aspects described above are not intended as required or essential elements unless explicitly stated otherwise.
Various modifications of, and equivalent acts corresponding to, the disclosed aspects of the example embodiments, in addition to those described above, can be made by a person of ordinary skill in the art, having the benefit of the present disclosure, without departing from the spirit and scope of the disclosure defined in the following claims, the scope of which is to be accorded the broadest interpretation so as to encompass such modifications and equivalent structures.
It should be understood that “a plurality” or “multiple” as referred to herein means two or more. “And/or,” describing the association relationship of the associated objects, indicates that there may be three relationships, for example, A and/or B may indicate that there are three cases where A exists separately, A and B exist at the same time, and B exists separately. The character “/” generally indicates that the contextual objects are in an “or” relationship.
In the present disclosure, it is to be understood that the terms “lower,” “upper,” “under” or “beneath” or “underneath,” “above,” “front,” “back,” “left,” “right,” “top,” “bottom,” “inner,” “outer,” “horizontal,” “vertical,” and other orientation or positional relationships are based on example orientations illustrated in the drawings, and are merely for the convenience of the description of some embodiments, rather than indicating or implying the device or component being constructed and operated in a particular orientation. Therefore, these terms are not to be construed as limiting the scope of the present disclosure.
Moreover, the terms “first” and “second” are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, elements referred to as “first” and “second” may include one or more of the features either explicitly or implicitly. In the description of the present disclosure, “a plurality” indicates two or more unless specifically defined otherwise.
In the present disclosure, a first element being “on” a second element may indicate direct contact between the first and second elements, without contact, or indirect geometrical relationship through one or more intermediate media or layers, unless otherwise explicitly stated and defined. Similarly, a first element being “under,” “underneath” or “beneath” a second element may indicate direct contact between the first and second elements, without contact, or indirect geometrical relationship through one or more intermediate media or layers, unless otherwise explicitly stated and defined.
Some other embodiments of the present disclosure can be available to those skilled in the art upon consideration of the specification and practice of the various embodiments disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present disclosure following general principles of the present disclosure and include the common general knowledge or conventional technical means in the art without departing from the present disclosure. The specification and examples can be shown as illustrative only, and the true scope and spirit of the disclosure are indicated by the following claims.
