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.
The 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 may 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. 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 top that corresponds the region in the display module assembly 100. 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 example, in an environment where the electronic device is well illuminated outdoors or indoors, light outside the electronic device may illuminate 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. In addition, according to the basic parameters of the PN junction 300, the intensity of light received by the PN junction 300 can be determined by the value of the output voltage of the PN junction 300, and in this case, the brightness of the environment where any display area on the electronic device is located can be determined by the change of the value of the output voltage of the PN junction 300, so as to correspondingly adjust the display brightness of the leds in each display area.
The display module 100 and each of the photo PN junctions 300 are connected to a processor, and specifically, the display module 100 and 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 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 may receive an output voltage value of each of the photo PN junctions 300, and may control a working state of a corresponding unit pixel in the display module 100.
The processor may adjust the brightness of the corresponding unit pixel according to the variation value of the output voltage of each photoelectric PN junction 300. In detail, in the working process of the electronic device, the photo PN junction 300 can receive the light on the display side of the display module 100 in real time, and the value of the output voltage of the photo PN junction 300 changes with the change of the light intensity, so that the processor can correspondingly control the display brightness of the display area according to the change of the light intensity.
The variation value of the output voltage of the opto-electric PN junction 300 is specifically the difference between the real-time value and the initial value of the opto-electric PN junction. The initial value may be a preset fixed value, the processor performs a difference between a real-time value of the output voltage of the photoelectric PN junction 300 and the initial value to obtain a variation value of the output voltage, and then, in combination with a basic parameter of the photoelectric PN junction 300, the illumination variation condition of the display area where the photoelectric PN junction 300 is located, that is, a difference between the preset illumination condition and a real-time illumination condition of the display area where the photoelectric PN junction 300 is located, may be determined, according to the difference, the processor may determine a brightness adjustment amplitude and an adjustment direction of a unit pixel corresponding to the photoelectric PN junction 300, where the adjustment amplitude is a magnitude of a variation of brightness, and the adjustment direction includes two adjustment directions of increasing the brightness or decreasing the brightness.
Alternatively, the initial value may be a real-time value of the output voltage at a time point before the time point at which the output voltage of the opto-electric PN junction 300 is the real-time value. For example, if the real-time value of the output voltage of the opto-electric PN junction 300 at the second time is the second voltage, the initial value may be the real-time value of the output voltage of the opto-electric PN junction 300 at the first time, which is recorded as the first voltage, and the first time is earlier than the second time, and the interval between the two may be determined according to the actual situation. In this case, the processor can also obtain whether the lighting environment of each display area in the display module 100 changes over time, specifically, if the second voltage is equal to the first voltage, it can be considered that the lighting environment of the electronic device does not change, and the processor can control the display brightness of the unit pixel corresponding to the photoelectric PN junction 300 to be unchanged; correspondingly, if the second voltage is different from the first voltage, it can be considered that the lighting environment of the corresponding unit pixel is changed, and the processor controls the brightness of the unit pixel corresponding to the photoelectric PN junction 300 to be changed according to the difference between the second voltage and the first voltage, i.e. the change value of the output voltage of the photoelectric PN junction 300.
Meanwhile, the change value is positively correlated with the brightness change condition of the corresponding unit pixel, in particular, when the change value is a positive value, it indicates that the illumination intensity of the environment in which the area corresponding to the photoelectric PN junction 300 is located is weakened, in this case, the processor may control the unit pixel to correspondingly reduce the brightness; in the case that the variation value is negative, the illumination intensity of the environment in which the area corresponding to the photoelectric PN junction 300 is located becomes stronger, in this case, the processor may control the boosted brightness corresponding to the unit pixel.
The application provides an electronic equipment, it includes display module assembly 100, photoelectricity PN junction 300 and treater, the demonstration side of display module assembly 100 is provided with two at least photoelectricity PN junctions 300, display module assembly 100 and each photoelectricity PN junction 300 all are connected with the treater, each photoelectricity PN junction 300 one-to-one sets up on a unit pixel, photoelectricity PN junction 300 is in the condition that received light intensity changes, the size of output voltage value is also different, the treater can be according to the change value of the output voltage of each photoelectricity PN junction 300, adjust the luminance of the unit pixel that corresponds, and at the in-process that the treater was adjusted, the change value is positive correlation with the luminance change condition of the unit pixel that corresponds. When the user touches the display module 100 to slide the display interface during the use of the electronic device, the living body such as the finger of the user or other objects may block the falling point region of the sliding operation, at this time, the user cannot see the blocked region in the display module 100, and the focus of the user is not in the region, and the brightness of the area will not have any adverse effect on the normal use of the display module 100, therefore, by adopting the above technical solution, in the case where a living body such as a user's finger or other object blocks one or more opto-electronic PN junctions 300, the brightness of one or more unit pixels 110 corresponding to the aforementioned opto-electronic PN junction 300 is reduced by the processor, the power consumption of one or some unit pixels 110 can be reduced under the condition that the use of the electronic equipment by a user is not influenced, and the cruising ability of the electronic equipment is improved.
In addition, in the electronic device provided in the above embodiment, the plurality of photoelectric PN junctions 300 may be used to replace a conventional infrared photosensitive sensor, so that the electronic device can automatically adjust the overall brightness of the display module 100. Specifically, the plurality of photoelectric PN junctions 300 may respectively obtain the illumination condition of the environment outside the display surface of each corresponding unit pixel 110, so that the processor may correspondingly determine the brightness required for the display of each unit pixel 110. Of course, under the condition that the variation values of the output voltages of the respective photoelectric PN junctions 300 are not very different, it can be considered that the shielding conditions of the display areas of the display module 100 of the electronic device are consistent, and are all shielded or not shielded, and at this time, the display brightness of the whole display module can be controlled by the processor to be the same or substantially the same. The relationship between the display area and the display brightness and the variation value of the output voltage of the photoelectric PN junction 300 may be a linear relationship, or may be other relationships, which is not limited herein.
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.
And, the processor may adjust the brightness of the corresponding display region according to the variation value of the output voltage of each photoelectric PN junction 300. That is, the luminance of the display region having a relatively large area is controlled by one or more opto-electric PN junctions 300 disposed in each display region to cover a relatively small area. Because the shielded area of the user in the process of touching to control the electronic equipment is certainly far larger than the area of one unit pixel, by adopting the technical scheme, the cruising ability of the electronic equipment can be greatly improved under the condition of basically not influencing the normal use of the electronic equipment.
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 PN junctions 300, and optionally, the number of the photo PN junctions 300 is the same as the number of the display areas, and the photo PN junctions 300 are arranged in a one-to-one correspondence, that is, each display area is provided with one photo PN junction 300, in this case, when any one or more display areas are blocked by a living body or an object, the processor can be ensured to control the display brightness of the corresponding display area to change according to the light intensity change received by the photo PN junctions 300.
As described above, the arrangement of the plurality of display areas is various, 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, compared with the technical scheme that the display areas are arranged along a certain direction, the display module 100 can be divided more normatively under the condition of adopting the technical scheme, so that no matter which 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 output voltage value of the corresponding photoelectric PN junction 300 to change, and the reliability of the photoelectric PN junction 300 as the basis for detecting whether the shielding object exists above the display areas 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, when one photoelectric PN junction 300 is disposed on each display area, the size of each display area can be relatively small, which can reduce the range size of the area represented by each photoelectric PN junction 300, so as to prevent the area of the corresponding photoelectric PN junction 300 in the display area, which cannot be shielded, from being in a shielded state, and thus the processor cannot know that the display area is shielded because the output voltage value of the photoelectric PN junction 300 is not changed.
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 photo PN junction 300, and since the size of the unit pixel 110 is extremely small, as long as the display module 100 is shielded by an external living body or object, the shielding situation can be represented by the change of the output voltage value of the photo PN junction 300 corresponding to the unit pixel 110, so that the processor can determine the shielded area on the display module 100 according to the position of the photo PN junction 300 where the output voltage value changes, and determine the change value of the display brightness of the display module 100, which needs to be adjusted, according to the change value of the output voltage value of the photo PN junction 300. 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 condition 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.
Further, the opto-PN junction 300 may be disposed in the middle of the light emitting diode along its length. In this case, the position of the photo PN junction 300 is relatively centered, so that the detection effectiveness of the photo PN junction 300 can be further improved in the process of determining the display brightness of the unit pixel 110 corresponding to the change value of the output voltage of the photo PN junction 300. Specifically, when the above technical solution is adopted, under the condition that the output voltage value of the photoelectric PN junction 300 changes, it can be considered that at least half of the area in the display area is blocked, at this time, the user cannot see the unit pixel 110 basically, and the processor reduces the display brightness of the unit pixel 110, so that the power consumption of the electronic device is reduced, and the normal viewing of the display module by the user is not affected basically. Correspondingly, if only a small portion of the unit pixel 110 is blocked, the brightness of the light received by the photo PN junction 300 will not change or the change amount is relatively small, in this case, the user can still see a large portion of the unit pixel 110, and since the output voltage value of the photo PN junction 300 is not changed or the change amount is small, the unit pixel 110 can still maintain the brightness, and the user can still view the display content of the unit pixel 110.
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. For example, the colors of the light emitted by the three elements may be red, green and blue, respectively, in which case, it can be ensured that each unit pixel 110 can normally display a color image, and the overall structure is relatively simple, and is convenient for assembly and production.
Based on the above-described structure of the unit pixel 110, alternatively, the display sides of the first, second, and third light emitting diodes 111, 112, and 113 may each be provided with a portion of the photo PN junction 300, that is, the photo PN junction 300 spans the first, second, and third light emitting diodes 111, 112, and 113. In this case, the light emitting uniformity of the first light emitting diode 111, the second light emitting diode 112, and the third light emitting diode 113 can be better, the light emitting effect of each unit pixel 110 can be improved, and the display quality of the display module 100 can be improved.
Further, as shown in fig. 2, the photoelectric PN junction 300 may include a photovoltaic conversion part 310, an anode 320, and a cathode 330, the anode 320 and the cathode 330 are both connected to the photovoltaic conversion part 310, the photovoltaic conversion part 310 may convert light energy into electric energy, and a voltage is output through the anode 320 and the cathode 330. Both the anode 320 and the cathode 330 may be connected to the processor to enable the processor to receive the value of the output voltage generated by the opto-electronic PN junction 300.
In the process of arranging the photo PN junctions 300, the anodes 320 of the photo PN junctions 300 may be located on the same side of the corresponding photovoltaic conversion parts 310, for example, the anodes 320 of the photo PN junctions 300 may be located on the left side of the photovoltaic conversion parts 310, and correspondingly, the cathodes 330 of the photo PN junctions 300 may be located on the right side of the photovoltaic conversion parts 310. Under this condition, be convenient for install photoelectricity PN junction 300 on the one hand, on the other hand can make arranging of photoelectricity PN junction 300 comparatively regular, is favorable to promoting display module assembly 100's demonstration homogeneity. The anode 320 of each PN junction 300 may be extended in the same direction, and the cathode 330 of each PN junction 300 may be extended in the same direction. In this case, the wiring work of each opto-electric PN junction 300 is facilitated, and the operational reliability of each opto-electric PN junction 300 can be improved.
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 brightness control method, which can be applied to the electronic device provided in any of the embodiments, where the brightness control method includes:
and S1, under the condition that the electronic equipment is shielded, receiving the change values of the output voltages of at least two photoelectric PN junctions. Specifically, a device for measuring the voltage magnitude may be connected to each of the PN junctions to output a voltage to the outside when the PN junctions are illuminated by light, and when the electronic device is shielded, the output voltage of the PN junctions may change, that is, a change value may be obtained, where the change value is a difference between a real-time value and an initial value of the PN junctions. Based on the physical parameters of the photoelectric PN junction, the change condition of the ambient illumination intensity of the unit pixel corresponding to the photoelectric PN junction in the display module can be obtained.
And S2, adjusting the brightness of the corresponding unit pixel in the electronic equipment according to the change value.
Specifically, the brightness of the unit pixel corresponding to the photoelectric PN junction in the electronic device may be adjusted according to the obtained variation value, the specific magnitude, the positive and negative, and the like of the variation value. Wherein, in the process of adjusting the brightness of the corresponding unit pixel, the change condition of the brightness is positively correlated with the change value of the output voltage. In more detail, in the case that the variation value is a positive value, it is considered that the illumination intensity of the environment in which the unit pixel is located is increased, and the luminance of the unit pixel may be enhanced in the process of adjusting the luminance of the unit pixel. On the contrary, in the case that the variation value is negative, the luminance of the unit pixel needs to be decreased. The adjustment range of the brightness is also related to the magnitude of the variation value, and when the absolute value of the variation value is relatively large, the adjustment range of the brightness is relatively large, and conversely, the adjustment range is small.
Further, the step S1 includes:
s11, receiving initial values of output voltages of at least two photoelectric PN junctions under the condition that the electronic equipment is not shielded;
s12, receiving real-time values of output voltages of at least two photoelectric PN junctions under the condition that the electronic equipment is shielded;
and S13, receiving the change value of the output voltage of at least two photoelectric PN junctions, wherein the change value is the difference value between the real-time value and the initial value.
Specifically, the initial value is a voltage value output when the photoelectric PN junction is not shielded, and correspondingly, the real-time value is a voltage value output when the photoelectric PN junction is shielded, in which case, the actual size of the initial value changes correspondingly with the illumination condition of the environment where the electronic device is located, rather than being fixed, so that the electronic device can more flexibly determine the adjustment condition required for the brightness of the corresponding unit pixel, and the adaptability of the electronic device to the brightness adjustment of the unit pixel is improved.
In addition, if the real-time values of the output voltages of the photoelectric PN junctions are all decreased from the initial values, and the decreased amplitudes are basically the same, the electronic equipment is moved to a dark environment as a whole. At the moment, the brightness of each unit pixel in the whole display module is reduced, so that the glasses of a user adapt to a darker environment, the electric quantity of the electronic equipment can be saved, and the cruising ability of the electronic equipment is improved. Correspondingly, if the real-time value of the output voltage of only a part of the plurality of photoelectric PN junctions is reduced from the initial value, it indicates that the unit pixel corresponding to the photoelectric PN junction is blocked by a living body or an object. At this moment, because the user is sheltered from and also can't see the content of this unit pixel, and the size of unit pixel is less than the size of live body or object far away to can divide into a plurality of interconnect's display area with the display module assembly, and make all be provided with at least one photoelectricity PN junction in each display area, with under the condition that the output voltage value of photoelectricity PN junction reduces, control the whole reduction of luminance of the display area that this photoelectricity PN junction is located, in order to save electronic equipment's electric quantity, when promoting electronic equipment's duration, still can not influence the user and normally use electronic equipment.
Based on the foregoing embodiment, further, the foregoing step S2 includes:
and S21, adjusting the brightness of the corresponding unit pixel in the electronic device according to the variation value, and adjusting the brightness of the corresponding unit pixel to the minimum brightness when the real-time value is smaller than the preset value. That is to say, in the process of adjusting the display brightness of the display module of the electronic device by using the variation value as the standard, the real-time value may be compared with the preset value, and when the real-time value is smaller than the preset value, the display brightness of the corresponding unit pixel may be adjusted to the minimum brightness. Specifically, the actual size of the preset value may be determined according to an actual situation, and accordingly, the minimum brightness may be zero, that is, a screen-turning state, or the minimum brightness may also be a brightness value that is not zero, which is not limited herein. In addition, as described above, the display module may be divided into a plurality of display areas, and in this case, when the real-time value of the PN junction is smaller than the preset value, the luminance of the display area corresponding to the PN junction may be controlled to the minimum luminance.
In the use process of the electronic equipment, under the condition that one or more display areas are shielded by living bodies or objects seriously in the display module, the shielding influence is caused, and a user can not check the content displayed by the display areas basically.
In addition, in the above technical solution, if the real-time values of the output voltages of the respective photoelectric PN junctions are all smaller than the preset value, it may be that the whole display module of the electronic device is blocked; or the environment where the electronic device is located is dark. Wherein, if the former, and the luminance of display module assembly 100 is not enough to guarantee user's normal use, then can increase display module assembly's luminance through double-click or pressing modes such as display module assembly, perhaps, can increase display luminance through modes such as dragging brightness control strip, guarantee that the user still can normal use electronic equipment in comparatively dark environment. If the display module is shielded, the user cannot normally check the display module, and the processor can reduce unnecessary electric quantity expenditure and improve the cruising ability of the electronic equipment by keeping the display module at the minimum brightness.

In the technical scheme, the brightness of the unit pixel is adjusted according to the change value of the output voltage, so that the electric quantity of the electronic equipment can be saved and the cruising ability of the electronic equipment can be improved under the condition that the normal use of a user is not influenced.
