So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
FIG. 1 is a first schematic flow chart illustrating an implementation of a control method according to an embodiment of the present invention; the electronic device includes a light emitting device; as shown in fig. 1, the method includes:
step 101: after receiving a first application program starting instruction, starting a first application program;
step 102: adjusting a first parameter of the light-emitting device through the first application program, and controlling the electronic equipment to be in a first working state or a second working state;
the first working state is used for representing the state that the light-emitting device works in a first mode so that the electronic equipment has a light sensing function;
the second working state is used for representing the state that the light-emitting device works in a second mode to enable the electronic equipment to have a backlight function.
In this embodiment, the electronic device may specifically be an electronic device with a light emitting device, such as a mobile phone and a tablet computer.
In this embodiment, the light emitting device is a Light Emitting Diode (LED) array; specifically, the light emitting device is an LED array composed of inorganic LEDs with multiple emission wavelengths such as red (R), green (G), and blue (B); wherein, the inorganic LED material corresponding to the red light is gallium arsenide phosphide (GaAsP) compound; the inorganic LED materials corresponding to the blue light and the green light are indium gallium nitride/gallium nitride (InGaN/GaN) compounds.
In an embodiment, the electronic device adjusts a first parameter of the light emitting device to make the first parameter have a first characteristic, for example, the first parameter is a voltage parameter applied to the light emitting device, and a parameter value corresponding to the voltage parameter has a first direction relative to the light emitting device, that is, a voltage applied to the light emitting device is a forward bias voltage, at this time, the electronic device is in the second working state, the light emitting device is an active light emitting source, and the electronic device can implement a backlight function by using the light emitting device.
Further, when the electronic device adjusts a first parameter of the light emitting device to make the first parameter have a second characteristic, for example, the first parameter is specifically a voltage parameter applied to the light emitting device, and a parameter value corresponding to the voltage parameter has a second direction relative to the light emitting device, where the second direction is different from the first direction, that is, a voltage applied to the light emitting device is a reverse bias voltage, at this time, the electronic device is in the first working state, the light emitting device is a light sensor, and the electronic device can implement a light sensing function by using the light emitting device.
When the voltage applied to the light emitting device is reverse bias voltage and the light emitting device is a light sensor, each LED in the lighting arrangement may be present as a photodetector for the corresponding light emission wavelength, in particular, as many sub-pixels per LED as many photoreceptors, for example, a white LED has RGB three-color sub-pixels, where each sub-pixel is a photoreceptor with a corresponding wavelength, i.e., multiple photoreceptors make up a light detector, multiple light detectors make up a light sensor, thus, the light-emitting device according to the embodiment of the invention can form a Complementary Metal Oxide Semiconductor (CMOS) matrix similar to a camera, and then, a photosensitive function is realized, for example, background light intensity detection, image acquisition, service time detection of an LED array, transparent fingerprint detection and the like are realized by utilizing the light-emitting device.
In this embodiment, the voltage applied to the light emitting device is a reverse bias voltage, the light emitting device is a photosensor, and at this time, the parameters affecting the light sensing function of the light emitting device are an open-circuit voltage, a short-circuit current, a temperature, and the like applied to the light emitting device; for example, the larger the reverse open-circuit voltage applied to the light emitting device, the smaller the light sensing current of the light emitting device, and the worse the light sensing function. It should be understood by those skilled in the art that in practical applications, the reverse voltage applied to the light emitting device can be arbitrarily set according to the actual required light sensing function.
Therefore, the working state of the electronic equipment is controlled by controlling the first parameter corresponding to the light-emitting device of the electronic equipment, so that the electronic equipment realizes the light-sensing function by using the light-emitting device on the premise of realizing the backlight function by using the light-emitting device, and therefore, the electronic equipment for realizing the method provided by the embodiment of the invention can also have the light-sensing function on the premise of not additionally arranging other light sensors, and the cost of the electronic equipment is reduced.
FIG. 2 is a schematic diagram illustrating the operation of a light emitting device under reverse bias according to an embodiment of the present invention; as shown in fig. 2, when a reverse bias is applied, that is, the voltage applied to the light emitting device is a reverse bias, and as shown in fig. 2, the voltage applied to the LED in the light emitting device is a reverse bias, and the light emitting device is illuminated by the background light, photons in the LED are converted into carriers, and the carriers drift under the action of the internal electric field, at this time, the external electric field widens the space charge region, so that the internal electric field is strengthened, the progress of diffusion motion is prevented, the progress of drift motion is strengthened, a reverse current, that is, a photosensitive current is formed, and thus, a photosensitive function is achieved.
Example two
Based on the control method in the first embodiment, in the embodiment of the present invention, the controlling the electronic device in the first working state includes:
acquiring an ambient light parameter corresponding to the electronic equipment by using the light-emitting device working in the first mode; storing the ambient light parameter.
In this embodiment, when the electronic device is in a first operating state, that is, the voltage applied to the light emitting device is a reverse bias voltage, and the light emitting device is a light sensor, the electronic device can acquire an environment corresponding to the electronic device by using the light emitting device as the light sensor, that is, an ambient light parameter of the environment where the electronic device is located, and further store the ambient light parameter.
Specifically, the method further comprises:
when the electronic equipment is in the second working state, the stored ambient light parameters are obtained;
and adjusting the light-emitting parameters corresponding to the light-emitting device according to the acquired environment light parameters, so that the light-emitting parameters are matched with the environment light parameters.
Specifically, when the voltage applied to the light emitting device is a reverse bias voltage and the light emitting device is a light sensor, three color light sensors of (R), green (G) and blue (B) in the light sensor are used to measure a three color light ratio of the background light in the environment corresponding to the electronic device, so as to obtain an environment light parameter, such as a CIE color coordinate and a color temperature, and the CIE color coordinate and the color temperature are fed back to the control circuit and stored. When the electronic equipment is in a second working state, namely the voltage applied to the light-emitting device is forward bias, and the light-emitting device is an active light-emitting source, the CIE color coordinate and the color temperature are obtained, and then the light-emitting parameters of the light-emitting device are adjusted through the control circuit according to the CIE color coordinate and the color temperature, so that the light-emitting device of the electronic equipment realizes the color temperature, the color coordinate and the color rendering index which are consistent with the background light, and the detection of the background light intensity is realized.
EXAMPLE III
Based on the control method in the first embodiment, in the embodiment of the present invention, the controlling the electronic device in the first working state includes:
acquiring first characteristic parameter information corresponding to the light emitting diodes in the light emitting diode array by using the light emitting device working in the first mode;
judging whether first characteristic parameter information corresponding to the light emitting diodes in the light emitting diode array meets a first preset rule or not;
and when the judgment result represents that the first characteristic parameter information corresponding to the light emitting diodes in the light emitting diode array meets the first preset rule, recording the identification of the light emitting diodes of which the first characteristic parameter information meets the first preset rule.
In this embodiment, the first characteristic parameter information is information corresponding to a light sensing parameter when the light emitting device realizes a light sensing function; specifically, the first characteristic parameter information is a light sensing current corresponding to the light emitting device when the light emitting device realizes a light sensing function.
In this embodiment, the first preset rule may specifically be that first characteristic parameter information corresponding to the light emitting diodes in the light emitting diode array is within a threshold range; specifically, the first preset rule may specifically be that a light sensing current corresponding to a light emitting diode in the light emitting diode array is within a first current threshold range.
In this embodiment, after the electronic device records the identifier of the light emitting diode of which the first characteristic parameter information satisfies the first preset rule, the method further includes:
when the electronic equipment is in the second working state, acquiring the identifier of the light emitting diode meeting the first preset rule;
and adjusting a second parameter of the light emitting diode corresponding to the identifier according to the identifier so as to enable the adjusted light emitting diode to be in a normal working state.
That is to say, when the reverse bias voltage is a reverse bias voltage, that is, the voltage applied to the light emitting device is a reverse bias voltage, and the light emitting device is a light sensor, the electronic device determines the identifier of the light emitting diode of which the first characteristic parameter information satisfies the first preset rule by using the light emitting device having a light sensing function, and further, when the forward bias voltage is a forward bias voltage, that is, the voltage applied to the light emitting device is an active light emitting source, the electronic device adjusts a second parameter, such as a current, of the light emitting diode corresponding to the identifier according to the recorded identifier, so that the adjusted light emitting diode is in a normal operating state, that is, the current of the adjusted light emitting diode is within a second current threshold range.
In a specific embodiment, since the electronic device utilizes the backlight function and the light sensing function of the same light emitting device, the reverse light sensing characteristic of the light emitting device is directly proportional to the forward light emitting characteristic, that is, under the same background light irradiation, when a light sensing current of a certain LED, for example, a first LED in the LED array, is significantly smaller than that of other LEDs in the LED array under a reverse bias, it indicates that the light sensing current is significantly smaller than that of the first LED of other LEDs, and therefore, when the voltage applied to the light emitting device is a forward bias, the light sensing current is significantly smaller than that of the first LED of other LEDs, so that the light emitting intensity of the LED array in the light emitting device is uniform.
In another embodiment, the method of the embodiment of the invention can also be used for detecting the service time of the LED array; specifically, as the service time of the LED is prolonged, the aging phenomenon of the LED becomes obvious, so that under the same background light irradiation condition, compared with an aged LED, a newer LED has a larger light sensing current and a smaller light sensing current, and therefore, by using the above principle, the purpose of detecting the service time of the LED array can be achieved through the light sensing current, the existing detection method for detecting the service time of the LED array is increased, and the user experience is enriched.

step 302: when the parameter value of the first parameter has the preset change rule, acquiring second characteristic parameter information of user operation applied to a display area of the electronic equipment; the second characteristic parameter information is used for representing the reflected light intensity characteristic corresponding to the operation body of the first operation;
step 303: and determining physiological characteristic parameters of the operation body corresponding to the user operation according to the reflected light intensity characteristics represented by the second characteristic parameter information.
In a specific embodiment, the driving circuit corresponding to the light emitting device is controlled to make the current corresponding to the light emitting device have a preset variation rule, for example, the current corresponding to the light emitting device has a rule of a sawtooth wave between positive 5V and negative 5V, at this time, the light emitting device is switched from the second working state to the first working state, and then switched from the first working state to the second working state, so as to reciprocate, that is, the light emitting function and the light sensing function of the electronic device are continuously switched, when an operating body, such as a finger, is on a display screen of the electronic device, the electronic device is in the second working state, that is, when the light emitting device is used as an active light emitting source, the reflection light intensity of the LED light formed at different places of the fingerprint is different due to reflection of the fingerprint, and further, when the electronic device is switched to the first working state, the light intensity sensed by the light emitting device serving as the light sensor is different, so that the aims of fingerprint scanning and fingerprint detection are fulfilled.

and generating an image corresponding to the target body according to the image characteristic information.
In this embodiment, since the light-emitting device can form a CMOS matrix similar to a camera, the light-emitting device with a light-sensing function is used as a photoreceptor corresponding to image pickup, photography, or even projection, so as to realize an image capturing function.
