Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 5, the present application discloses an electronic device, which includes a display module 100, an opto-electronic PN junction 300 and a processor, and of course, the electronic device further includes a housing 500, a main board, a battery and other components, which are not described herein again in view of brevity.
Each display module 100 includes a plurality of unit pixels 110, and more specifically, each unit pixel 110 includes a light emitting diode, and the plurality of unit pixels 110 can form a display layer of the display module 100 by the light emitting diodes to provide a display function. In the display module 100, each led can be independently powered, that is, the electronic device can control the plurality of leds to operate respectively. Of course, the light emitting diodes can also be supplied with power together, so that the processor can control the display brightness of the display module and the like together. In the foregoing process, the processor may provide the control instruction.
The number of the opto-electric PN junctions 300 is at least two, and specifically may be two, three, four or more. At least two photoelectric PN junctions 300 are installed on at least two unit pixels 110 in a one-to-one correspondence, that is, one photoelectric PN junction 300 is installed on one unit pixel 110, correspondingly, only one photoelectric PN junction 300 is also installed on any one unit pixel 110 on which the photoelectric PN junctions 300 are installed, and the photoelectric PN junctions 300 are installed in a one-to-one correspondence when the number of the photoelectric PN junctions 300 is equal to the number of the unit pixels 110, and certainly, the photoelectric PN junctions 300 are not installed on a part of the unit pixels 110 when the number of the photoelectric PN junctions 300 is less than the number of the unit pixels 110.
Each photoelectricity PN junction 300 all installs the demonstration side at the display module assembly to guarantee that photoelectricity PN junction 300 can receive the light that comes from the display module assembly 100 demonstration side, the intensity of the light that comes from the demonstration side can characterize the light intensity of the environment that display module assembly 100 is located, and whether there is the condition such as sheltering from in the display module assembly 100 arbitrary display area top. The photoelectric PN junction 300 may be fixed to the photodiode by bonding with transparent adhesive or the like, or the photoelectric PN junction 300 may be fixed to the display side of the display module 100 by other fixing structures, so as to ensure that the photoelectric PN junction 300 can stably receive light outside the display side.
The photo PN junction 300 can change the output voltage value according to the received light intensity, that is, the output voltage value of the photo PN junction 300 can change, and the change condition is related to the light intensity received by the photo PN junction 300, and the output voltage value can also change when the light intensity received by the photo PN junction 300 changes. Generally, the output voltage of the opto-electrical PN junction 300 is positively correlated to the light intensity received by the opto-electrical PN junction 300, that is, the greater the light intensity received by the opto-electrical PN junction 300, the greater the output voltage of the opto-electrical PN junction 300. For convenience of description, in the case that no other description is given, the output voltage value of the photoelectric PN junction 300 is in a positive correlation with the light intensity, for example, when the electronic device is in an environment with good outdoor or indoor illumination, light outside the electronic device may irradiate the photoelectric PN junction 300, the photoelectric PN junction 300 may receive strong illumination, and the output voltage value is relatively large; in the case of poor light at night or indoors, the intensity of the light received by the photoelectric PN junction 300 is weak, and the output voltage is relatively small.
The display module 100 and each of the photo PN junctions 300 are connected to a processor, and specifically, the display module 100 and each of the photo PN junctions 300 may be directly connected to the processor through a wire or a flexible circuit board, or the display module 100 and each of the photo PN junctions 300 may be indirectly connected to the processor through a main board or a sub-board of an electronic device, which may ensure that the processor can receive an output voltage value of each of the photo PN junctions 300, and correspondingly control a display frame rate of the display module 100 according to the output voltage value.
Specifically, the processor may include a central processing unit and a graphic processing unit, so that the processor can adjust the number of pixels output by itself according to the relationship between the output voltage value of each photoelectric PN junction 300 and a preset range, and change the display frame rate of the display module. In detail, in the working process of the electronic device, the photoelectric PN junction 300 may receive light from the display side of the display module 100 in real time, and when the light intensity changes, the output voltage value of the photoelectric PN junction 300 also changes, so that the processor correspondingly controls the display frame rate of the display module when the output voltage value meets the preset range. Of course, it should be noted that, in order to ensure that the display frame rate of the display module can be normally increased, the refresh rate of the display module needs to satisfy a certain condition, so as to prevent the frame rate from being wasted.
Specifically, in the working process of the electronic device, by comparing the output voltage value of the photoelectric PN junction 300 with the critical value of the preset range, it can be determined whether there is a living body or an object approaching to a position relatively close to the display module 100, and the processor can increase the display frame rate of the display module 100 when the output voltage value of the photoelectric PN junction 300 meets the preset range.
Wherein, the critical value of the preset range should be a voltage value output when the living body or the object is close to and shelters from the display module 100 and is not in contact with the display module 100, and the photoelectric PN junction 300 is sheltered from the living body or the object; moreover, the actual size of the critical value can be selected according to the actual situation, that is, the distance between the living body or the object and the display module 100 when the photoelectric PN junction 300 outputs the critical value can be determined according to the actual situations such as the photoelectric conversion performance of the photoelectric PN junction and the processing performance of the processor, which is not limited herein.
The embodiment of the application provides an electronic equipment, it includes display module assembly 100, photoelectricity PN junction 300 and treater, and the demonstration side of display module assembly 100 is provided with two at least photoelectricity PN junctions, and each photoelectricity PN junction is installed on a unit pixel 110 one-to-one, and display module assembly and each photoelectricity PN junction all are connected with the treater. When a living body or an object approaches the display module 100, the shielding effect of the living body or the object on the display module 100 is gradually enhanced, the intensity of the light received by the photoelectric PN junction 300 is gradually reduced, so that the output voltage value of the photoelectric PN junction 300 is continuously changed, when the output voltage value satisfies a preset range, it can be considered that the user has an idea of touching the display module 100 to control the electronic device to switch the display content, and further, after receiving that the output voltage value of the photoelectric PN junction 300 is within the preset range, the processor can increase the display frame rate of the display module, so as to increase the display frame rate in advance before the user touches the display module, so that when the user touches and slidingly controls the display content of the display module 100, the display frame rate of the display module is already in a relatively large state, and further when the display module switches the display content, the situation of blocking basically can not occur, and the user experience can be improved.
In addition, in the electronic device provided in the above embodiment, each of the photoelectric PN junctions 300 can be used to detect whether a living body or an object is approaching the display module 100. Wherein, under the condition that the output voltage value of each photoelectricity PN junction 300 all is located the default within range, can regard as the whole state that is in by sheltering from of electronic equipment's display module assembly 100, at this moment, because the user is sheltered from by living body or object and leads to also can't watch the display content of display module assembly, consequently, in order to save electronic equipment's electric quantity, can not promote the display frame rate of display module assembly, promote electronic equipment's duration, can reduce the display luminance of display module assembly even to further promote electronic equipment's duration.
Further, the display module 100 includes at least two display areas connected to each other, specifically, the number of the display areas may be two, three, four or more, and the distribution mode of the display areas may be determined according to parameters such as the shape of the display module 100. For example, the display module 100 may be a rectangular or approximately rectangular structural member, each display area may be in a rectangular or approximately rectangular structure, and the size of each display area may be determined according to the specific division condition of the display area, for example, each display area may be arranged along the length direction of the display module 100, and any two adjacent display areas are connected to each other. Correspondingly, when the shape of the display module 100 is other shapes, the shape of each display area can be determined according to actual conditions, and is not limited herein. It should be noted that, in order to ensure a better display effect and higher structural reliability, the display module 100 may have an integrated structure, that is, there may be no obvious physical partition boundary between the display regions in the display module 100.
Based on the above embodiments, optionally, at least one opto-electrical PN junction 300 is disposed in any one of the display regions, in which case, a plurality of opto-electrical PN junctions 300 may be disposed on the display module in a relatively dispersed manner. Specifically, one or more opto-electrical PN junctions 300 may be disposed in one display region, and the position of the opto-electrical PN junction 300 in the corresponding display region may be selected according to actual conditions, which is not limited herein.
Moreover, the processor can increase the display frame rate of the display module when the output voltage value of any one of the photoelectric PN junctions 300 is within the preset range. Under the condition of the technical scheme, even if the number of the photoelectric PN junctions 300 is small, the living body or the object can be effectively acquired to move close to the display module 100, so that the reliability of the electronic equipment is improved by touching the display module 100.
As described above, each of the plurality of unit pixels of the electronic device can be independently powered, and each of the display areas can be independently powered by using the above technical solution. For example, in the case that the display area includes a first display area and a second display area, the electronic device may individually control the light emitting diodes in the first display area to operate, and make the light emitting diodes in the second display area not operate, so that the first display area is in a lit state and the second display area is in a extinguished state.
As described above, each display area may be provided with the photo-electric PN junctions 300, and optionally, the number of the photo-electric PN junctions 300 is the same as the number of the display areas, and the photo-electric PN junctions 300 are arranged in a one-to-one correspondence manner, that is, each display area is provided with one photo-electric PN junction 300, in this case, when a living body or an object blocks any one or more display areas, the processor can control the display frame rate of the display module according to the relationship between the output voltage value of the corresponding photo-electric PN junction 300 and the preset range.
As described above, the plurality of display areas are arranged in various ways, and optionally, the plurality of display areas are arranged in rows and columns, that is, the number of the display areas is at least four, and compared with the technical scheme that the display areas are arranged in a certain direction, the display module 100 can be divided more normatively under the condition of adopting the above technical scheme, so that no matter what direction of the display module 100 the shielding object moves to the side of the display surface of the display module 100, the processor can rapidly receive the condition that the output voltage value of the corresponding photoelectric PN junction 300 changes, and the reliability of the photoelectric PN junction 300 as the basis for detecting whether the shielding object exists above the display area can be improved to a certain extent.
Specifically, in the case that the plurality of display regions are arranged in rows and columns, the shapes and sizes of the display regions may be correspondingly the same. Of course, the display module 100 is provided with a front-view opening, or the shapes of the display areas may be different when the four corners of the display module 100 are arc-shaped. In addition, under the condition that each display area is provided with one photoelectric PN junction 300, the size of each display area can be relatively small, the range size of the area represented by each photoelectric PN junction 300 can be reduced, and the situation that the corresponding photoelectric PN junction 300 in each display area cannot acquire the shielding situation is prevented from being in the shielding state, so that the output voltage value of the photoelectric PN junction 300 is not changed, the processor cannot know that the display area is shielded, the display frame rate of the display module cannot be normally increased, and the user experience is influenced.
Furthermore, the center of any display area can be provided with the photoelectric PN junction 300, and in this case, the uniformity of the arrangement of the photoelectric PN junction 300 on the display module 100 can be further improved, so that the sensing efficiency and reliability of each photoelectric PN junction on the shielding condition can be further improved under the condition that the number of the photoelectric PN junctions is relatively small.
Further, each unit pixel 110 in the display module 100 may be configured with the photo PN junctions 300, that is, the number of the photo PN junctions 300 is equal to the number of the unit pixels 110 in the display module 100, and the two are in one-to-one correspondence. In this case, any one of the unit pixels 110 corresponds to the photoelectric PN junction 300, and since the size of the unit pixel 110 is extremely small, whenever the external living body or object blocks the display module 100, the blocking condition can be represented by a change in the output voltage value of the photoelectric PN junction 300 corresponding to the unit pixel 110, and the display frame rate of the display module is increased by the processor when the output voltage value is within the preset range. Specifically, the size of the PN junction 300 is smaller than that of the unit pixel 110, so as to ensure that the light emitted by the light emitting diode in the unit pixel 110 after being energized can irradiate the outside of the display module 100. The size relationship between the photo PN junction 300 and the unit pixel 110 may be a compromise between the display effect and the photoelectric conversion efficiency, and is not limited herein.
As described above, the positional relationship between the photoelectric PN junction 300 and the unit pixel 110 can be determined according to actual situations, for example, the photoelectric PN junction 300 can be disposed at either end of the unit pixel 110 in the length direction thereof, or the photoelectric PN junction 300 can be disposed at either end of the unit pixel 110 in the width direction thereof; still alternatively, the photoelectric PN junction 300 may be disposed at a corner of the unit pixel 110.
In an embodiment of the present application, as shown in fig. 1, the distances between any two adjacent opto-electronic PN junctions 300 are equal, that is, the arrangement directions of the opto-electronic PN junctions 300 are the same, and the plurality of opto-electronic PN junctions 300 are uniformly arranged. In this case, the reliability of representing the ambient light-dark change around the display surface of each display region by the magnitude of the output voltage value of each photoelectric PN junction 300 can be further improved. Specifically, the positional relationship between each of the photo-PN junctions 300 and the corresponding unit pixel 110 may be the same, for example, each of the photo-PN junctions 300 is disposed at a specific end of each of the unit pixels 110, which may ensure that the distances between any two adjacent photo-PN junctions 300 are equal.
As described above, the relative position between each of the photo PN junctions 300 and the unit pixel 110 can be selected according to actual situations. Alternatively, as shown in fig. 2, each unit pixel 110 includes a first light emitting diode 111, a second light emitting diode 112, and a third light emitting diode 113 arranged side by side, and the light emitting colors of the first light emitting diode 111, the second light emitting diode 112, and the third light emitting diode 113 are different, that is, the colors of the light emitted by the three light emitting diodes are different from each other.

Based on the electronic device provided in any of the embodiments, as shown in fig. 6, an embodiment of the present application further provides a display frame rate control method, which is applied to the electronic device provided in any of the embodiments, and the display frame rate control method includes:
and S1, receiving the output voltage value of each photoelectric PN junction. Specifically, a device for measuring the voltage magnitude may be connected to each of the PN junctions to obtain the magnitude of the output voltage value of each PN junction when the PN junction is illuminated with light and the voltage is output to the outside.
And S2, under the condition that any output voltage value is within the preset range, increasing the display frame rate of the display module of the electronic equipment.
Specifically, in the working process of the electronic equipment, the output voltage value of the photoelectric PN junction is compared with the critical value of the preset range, whether a living body or an object is close to the position relatively close to the display module can be judged, and the display frame rate of the display module can be increased by the processor under the condition that the output voltage value of the photoelectric PN junction meets the preset range.
The critical value of the preset range should be a voltage value output when the living body or the object is close to and shelters from the display module and is not in contact with the display module, and the photoelectric PN junction is sheltered by the living body or the object, and the actual size of the critical value can be selected according to the actual situation, that is, the distance between the living body or the object and the display module when the photoelectric PN junction outputs the critical value can be determined according to the actual situations such as the photoelectric conversion performance of the photoelectric PN junction and the processing performance of the processor, and the like, and the preset range is not limited herein.
The above embodiment of the present application discloses a method for controlling a display frame rate of an electronic device, in which, when a living body or an object approaches a display module, a shielding effect of the living body or the object on the display module is gradually enhanced, and an intensity of light received by a photoelectric PN junction is gradually reduced, so that an output voltage value of the photoelectric PN junction is continuously changed, when the output voltage value satisfies a preset range, it can be considered that a user has an idea of touching the display module to control the electronic device to switch display contents, and further, after receiving a condition that the output voltage value of the photoelectric PN junction is within the preset range, a processor can increase the display frame rate of the display module, so as to increase the display frame rate in advance before the user touches the display module, so that when the user touches and slidingly controls the display contents of the display module, the display frame rate of the display module is in a relatively large state, so that the display module can be switched to display contents without jamming basically, and the user experience can be improved.
Further, the step S2 may include:
and S21, under the condition that at least one output voltage value is within the preset range and at least one output voltage value is outside the preset range, increasing the display frame rate of the display module of the electronic equipment. That is to say, when the output voltage value of a certain photoelectric PN junction does not satisfy the preset range and the output voltage value of a certain photoelectric PN junction satisfies the preset range among the plurality of photoelectric PN junctions installed on the display module, the processor controls the display frame rate of the display module to increase.
Under the condition of adopting above-mentioned technical scheme, can get rid of because of the luminance of the environment that electronic equipment is located is lower relatively for the luminous intensity that all photoelectricity PN junctions can be received on whole electronic equipment is all relatively less, thereby leads to even if living body or object such as user's finger do not shelter from the display module assembly, the output voltage value of photoelectricity PN junction also probably because of satisfying preset scope, and the condition that the treater misregistration shows the frame rate appears. Therefore, under the condition of adopting the technical scheme, the accuracy of the judgment result of whether the electronic equipment has the touch control display module group for switching the display content or not to the user can be improved, so that the user experience is improved, and meanwhile, the cruising ability of the electronic equipment is further improved.
Further, the step S2 may include:
and S22, increasing the display frame rate of the display module of the electronic device when any output voltage value meets the critical value of the preset range and the difference value between the output voltage value and the critical value is continuously increased or continuously decreased. The threshold value is an end value of the preset range, and in the process that the output voltage value changes from being outside the preset range to being within the preset range, the output voltage value is necessarily equal to the threshold value, that is, the output voltage value meets the threshold value of the preset range.
In the above-described embodiment, as shown in fig. 5, it is necessary to further determine the actual magnitude of the output voltage value. That is, it is determined whether the difference between the output voltage value and the threshold value continuously increases or continuously decreases. Under the condition that the output voltage value of the photoelectric PN junction is in positive correlation with the received light intensity, along with the fact that a living body or an object such as a finger of a user approaches the display module, the intensity of light received by the photoelectric PN junction corresponding to the living body or the object can be continuously reduced, the critical value of the preset range should be relatively smaller and at least smaller than the output voltage value of the photoelectric PN junction when the electronic equipment is in a normal light condition, in a period of time after the output voltage value is equal to the critical value, if the difference value between the output voltage value and the critical value is continuously reduced, the output voltage value is always reduced, the distance between the living body or the object and the display module is gradually reduced, and the user can be considered to have the touch control display module so as to switch the idea of display contents.
Correspondingly, under the condition that the output voltage value of the photoelectric PN junction is in negative correlation with the received light intensity, as a living body or an object such as a finger of a user approaches the display module, the intensity of light received by the photoelectric PN junction corresponding to the living body or the object is continuously reduced, the critical value of the preset range should be relatively larger and at least larger than the output voltage value of the photoelectric PN junction when the electronic device is in a normal light condition, and if the difference value between the output voltage value and the critical value is continuously increased within a period of time after the output voltage value is equal to the critical value, the output voltage value is continuously increased, and the distance between the living body or the object and the display module is gradually reduced, i.e. the user is considered to have the touch control display module to switch the idea of display contents.
Under the condition of adopting the technical scheme, as shown in fig. 4, if a living body or an object only passes through the upper part of the display module and does not continuously approach the display module, although the output voltage value of the corresponding photoelectric PN junction meets the preset range, the change condition of the output voltage value does not meet the above condition, the processor still cannot be triggered to increase the control content of the display frame rate, so that the accuracy of the processor in judging whether the touch control display module exists for the user to switch the display content can be improved, the user experience can be further improved, and the cruising ability of the electronic device can be improved.
Further, the display frame rate control method provided in the foregoing embodiment may further include, after step S1:
and S3, when the output voltage values are the same and the display content of the display module of the electronic equipment is static content, reducing the display frame rate of the display module to the minimum display frame rate. In detail, the static content may be text content, table content, or the like, and when the display content is the static content, the size of the display frame rate hardly affects the user to view the static content; meanwhile, under the condition that the ambient light levels of the display areas in the display module are the same or similar, it can be considered that no living body or object blocks the display module, and further, the idea that the user does not touch the display module to switch the display content in the next period of time is also explained. Therefore, under the condition that the conditions are met, the display frame rate of the display module can be reduced by the processor, and specifically, the display frame rate can be directly reduced to the minimum display frame rate, so that the overall power consumption of the electronic equipment is greatly reduced, the cruising ability of the electronic equipment is improved, and the normal use of the electronic equipment by a user is not influenced.
