1 shows an example electronic device that adaptively changes drive frequency.

Referring to FIG. 1 , the electronic device 101 can display a screen through the display 110 . For example, the screen may be displayed based on at least some of the subpixels in the display 110 emitting light. For example, the screen may be displayed based on the driving frequency for light emission of the subpixels. For example, the driving frequency may be identified among a plurality of driving frequencies based on the screen or the state of the electronic device 101. For example, the plurality of driving frequencies may include a first driving frequency and a second driving frequency higher than the first driving frequency.

For example, as in state 100, the electronic device 101 may display the screen through the display 110 based on the first driving frequency identified among the plurality of driving frequencies. For example, as in state 150, the electronic device 101 may display the screen through the display 110 based on the second driving frequency identified among the plurality of driving frequencies. For example, state 100 and state 150 may be provided within different contexts or states.

For example, the quality of the screen displayed based on the first driving frequency may be lower than the quality of the screen displayed based on the second driving frequency. For example, the electronic device 101 may display the screen according to the second driving frequency of the first driving frequency and the second driving frequency in order to express scene transitions more smoothly.

For example, power consumed by displaying the screen based on the first driving frequency may be lower than power consumed by displaying the screen based on the second driving frequency. For example, the electronic device 101 may display the screen according to the first driving frequency of the first driving frequency and the second driving frequency in order to reduce power consumed by the display 110. there is. As a non-limiting example, the electronic device 101 in a power saving mode displays the screen according to the first driving frequency among the first driving frequency and the second driving frequency. can do. As a non-limiting example, the electronic device 101 may display the screen including a static image according to the first driving frequency among the first driving frequency and the second driving frequency.

For example, the electronic device 101 may determine the type (or properties) of the screen, the state of the electronic device 101 related to the display of the screen, and/or the state of the environment surrounding the electronic device 101. , the driving frequency can be adaptively changed or adjusted.

2 is a simplified block diagram of an example electronic device.

Referring to FIG. 2, the electronic device 101 includes a processor 210, a display 110 including a display driving circuit 202 and a display panel 203, a power management integrated circuit (PMIC) 220, and It may include an illumination sensor 230.

For example, the processor 210 may include at least a portion of the processor 720 of FIG. 7 . For example, the display 110 may include at least a portion of the display module 760 of FIG. 7 or at least a portion of the display module 760 of FIG. 8 . For example, the display driving circuit 202 in the display 110 may include at least a portion of the display driver IC (DDI) 830 of FIG. 8. For example, the display panel 203 in the display 110 may include at least a portion of the display 810 of FIG. 8. For example, PMIC 220 may include at least a portion of power management module 788 of FIG. 7 . For example, the illuminance sensor 230 may include at least a portion of the sensor module 776 of FIG. 7 .

For example, the PMIC 220 may be used to provide power for displaying a screen to the display 110 based on control of the processor 210. For example, PMIC 220 may be used to provide current to emit light for each of the subpixels in display 110 (or subpixels in display panel 203). For example, PMIC 220 can be used to identify the current. However, it is not limited to this.

For example, the illuminance sensor 230 may be used to obtain or identify data indicating the illuminance around the electronic device 101. As a non-limiting example, the illuminance sensor 230 may be adjacent to one of the edges of the display 110 . The illuminance sensor 230 adjacent to the edge will be illustrated through the description of FIGS. 3 and 4. As a non-limiting example, the ambient light sensor 230 may be located within the display 110 (e.g., display panel 203) or below the display 110.

For example, the processor 210 may change the driving frequency based on the data representing the illuminance obtained through an illuminance sensor. For example, current leakage may be caused from at least some of the sub-pixels in display 110 (or display panel 203) by light from the outside. For example, the current leakage may reduce the brightness of the screen displayed based on the subpixels emitting light. For example, the decrease in brightness of the screen may cause a flicker phenomenon. For example, the processor 210 may perform at least one operation to reduce the flicker phenomenon. The at least one operation may be illustrated through FIGS. 3 and 4.

3 and 4 show examples of luminance being reduced by light from outside.

Referring to FIG. 3, each of the subpixels within the display 110 may be connected to a transistor. For example, the transistor may be directly connected to each of the subpixels. For example, the transistor may be connected to each of the subpixels through another transistor (or other electronic component). For example, the transistor may be a transistor electrically related to each of the subpixels.

For example, the transistor connected to each of the subpixels may be used to initialize or reset each of the subpixels. For example, the other transistor connected to each of the subpixels may be a transistor for driving each of the subpixels. However, it is not limited to this.

For example, the transistor (or the gate of the transistor) may be exposed to light from the outside. For example, current leakage may result from at least a portion of the subpixels connected to the transistor (or the gate of the transistor) exposed to the light. For example, since the current applied to the at least part of the subpixels is reduced by the current leakage, the brightness of light emitted from the at least part of the subpixels may be reduced.

For example, the chart 300 shows the brightness decreased according to the current leakage while the screen is displayed according to the first driving frequency, and the chart 350 shows the brightness decreased according to the second driving frequency. While the screen is displayed, it shows the brightness decreasing according to the current leakage. For example, the horizontal axis of each of the

charts

300 and 350 may represent time, and the vertical axis of each of the

charts

300 and 350 may represent brightness (or luminance). For example, as shown in chart 300, the brightness is a value within a portion 315 of the time interval 310 corresponding to the first driving frequency while the screen is displayed according to the first driving frequency. It can be reduced by (320). For example, as shown in chart 350, the brightness changes to a value within a portion 365 of the time interval 360 corresponding to the second driving frequency while the screen is displayed according to the second driving frequency. It can be reduced by (370). For example, because the portion 315 of the time interval 310 is longer than the portion 365 of the time interval 360, the slope of the line 325 within the portion 315 of the time interval 310 is the time interval ( Value 320 may be higher than value 370 , even though it is the same as the slope of line 375 within portion 365 of 360 . For example, since the value 320 is higher than the value 370, the probability of seeing a flicker phenomenon while displaying the screen according to the first driving frequency is The probability of seeing flicker may be higher. For example, since the value 370 is lower than the value 320, the probability of seeing a flicker phenomenon while displaying the screen according to the second driving frequency is the probability of displaying the screen according to the first driving frequency. The probability of seeing flicker may be lower than before.

For example, the processor 210 may acquire the data representing the illuminance through the illuminance sensor 230 while displaying the screen through the display 110 according to the first driving frequency.

For example, the processor 210 may adjust the driving frequency for emission of the subpixels from the first driving frequency to the second driving frequency based on identifying that the illuminance indicated by the data is higher than the reference illuminance. By changing the driving frequency, the screen can be displayed according to the second driving frequency. For example, since the fact that the illuminance is higher than the reference illuminance indicates that the probability that the flicker phenomenon will be seen while displaying the screen according to the first driving frequency is relatively high, the processor 210 The first driving frequency can be changed or adjusted to the second driving frequency.

For example, the processor 210 may maintain the driving frequency at the first driving frequency based on identifying that the illuminance indicated by the data is lower than or equal to the reference illuminance. The screen can be displayed according to the first driving frequency. For example, since the fact that the illuminance is lower than or equal to the reference illuminance indicates that the intensity of the current leakage is relatively low, the processor 210 reduces power consumption by displaying the screen. In order to reduce the driving frequency, the driving frequency may be maintained at the first driving frequency.

For example, the intensity (or amount) of light received from the outside to the illuminance sensor 230 is received from the outside as part of the display 110 (or display panel 203), depending on the state related to the electronic device 101. The intensity of light may be different. For example, data acquired through the illuminance sensor 230 based on light from the outside may indicate a different illuminance that is distinct from the illuminance corresponding to the intensity of light received as part of the display 110 from the outside. As a non-limiting example, when the illuminance sensor 230 is obscured by an external object, at least one transistor connected to at least one subpixel in the portion of the display 110 is exposed to light from the outside, The data acquired through the illuminance sensor 230 may indicate that the at least one transistor is not exposed to the light. For example, the processor 210 operates at the driving frequency under conditions where the state of light indicated by the data obtained through the illuminance sensor 230 is different from the state of light received from the outside to the part of the display 110. You can perform actions to change or adjust.

Referring to FIG. 4 , the illuminance sensor 230 may be located within the display 110 . For example, the illuminance sensor 230 may be located below the display panel 203. However, it is not limited to this.

For example, the display 110 (or display panel 203) may include first subpixels and second subpixels. For example, the first subpixels may be adjacent to the illuminance sensor 230 with respect to the second subpixels. For example, the first subpixels may be located in area 440 and the second subpixels may be located in area 490 .

As a non-limiting example, when the illuminance sensor 230 is obscured by an external object, the intensity of light received in area 440 may be less than the intensity of light received in area 490. For example, the state of light indicated by the data obtained through the illuminance sensor 230 corresponds to the state of light received from the outside to at least some of the first sub-pixels in the area 440, but the illuminance sensor ( The state of light indicated by the data obtained through 230) may be different from the state of light received from the outside to at least some of the second subpixels in the area 490. The extent to which the transistor connected to the at least part of the first subpixels in the area 440 is exposed to light from the outside is determined by the degree to which the transistor connected to the at least part of the second subpixels in the area 490 is exposed to light from the outside. It may be less than the level of exposure to light. For example, the intensity of current leakage resulting from the at least some of the first sub-pixels in area 440 while the screen is displayed based on the first driving frequency may be determined based on the first driving frequency. It may be less than the intensity of current leakage caused by the at least some of the second subpixels in the area 490 while the screen is displayed. For example, the magnitude of the current applied to the at least a portion of the first subpixels in the region 440 may be greater than the magnitude of the current applied to the at least a portion of the second subpixels in the region 490. . For example, the brightness of light from the at least a portion of the first subpixels in the area 440 may be higher than the brightness of the light from the at least a portion of the second subpixels in the area 490 .

For example, chart 400 shows the brightness of light from the at least some of the first sub-pixels in area 440 while the screen is displayed according to the first driving frequency, and chart 450 shows the brightness of light from the at least some of the second subpixels in the area 490 while the screen is displayed according to the first driving frequency. For example, the horizontal axis of each of the

charts

400 and 450 may represent time, and the vertical axis of each of the

charts

400 and 450 may represent brightness (or luminance). For example, as shown in chart 400, the brightness of light from the at least some of the first sub-pixels in area 440 may vary depending on the first driving frequency while the screen is displayed. may be reduced by a value 420 within a portion 415 of the time interval 410 corresponding to . For example, as shown in chart 450, the brightness of light from the at least a portion of the second sub-pixels in area 490 may vary depending on the first driving frequency while the screen is displayed. may be reduced by a value 470 within a portion 465 of the time interval 460 corresponding to . For example, the time section 410 may correspond to the time section 310 in FIG. 3 . For example, the intensity of light received from the outside to the at least part of the second subpixels within the area 490 is the intensity of light received from the outside to the at least part of the first subpixels within the area 440. Because it is greater than the intensity of light, value 470 may be higher than value 420. For example, the slope of the line 475 in the chart 450 may be greater than the slope of the line 425 in the chart 400. For example, the probability that a flicker phenomenon will be seen within the area 490 may be higher than the probability that a flicker phenomenon will be seen within the area 440 .

For example, the processor 210 may configure the sub-pixels of the display 110, including the first sub-pixels and the second sub-pixels, to reduce the flicker that may be visible within area 490. A value representing the current applied to each pixel can be identified. For example, the value may be identified through PMIC 220. For example, the value may be identified based on the difference between the source voltage and drain voltage of the transistor for driving each of the subpixels. However, it is not limited to this.

For example, the processor 210 may use the data indicating the illuminance lower than the reference illuminance, obtained through the illuminance sensor 230, to reduce the flicker phenomenon that may be visible within the area 490. Based on this, it is possible to identify whether a value representing a current applied to at least some of the subpixels (or at least a portion of the second subpixels) is lower than a reference value. For example, the reference value can be used to identify the intensity of current leakage due to exposure to light from the outside. As a non-limiting example, the reference value may be the value representing the current that was obtained or stored when the screen was previously displayed. For example, when the screen is repeatedly displayed, the processor 210 displays the at least some of the subpixels (or the at least a portion of the second subpixels) while the first display of the screen is performed. Based on storing the value representing the applied current as the reference value and identifying a second display of the screen (e.g., a re-display of the screen) following the first display of the screen, the first display identifies the reference value that was stored while the display was performed, and said at least some of the sub-pixels (or said at least a portion of the second sub-pixels) while the second display of the screen was performed based on the first driving frequency. It is possible to identify whether the value representing the current applied to the first display is lower than the reference value that was stored while the first display was executed.

For example, if the value is lower than the reference value, it indicates that the intensity of the current leakage is relatively large, and if the value is equal to or higher than the reference value, it indicates that the intensity of the current leakage is relatively large. It can indicate smallness.

For example, the processor 210 changes the driving frequency to the second driving frequency based on the value that is lower than the reference value and displays the screen through the display 110 according to the second driving frequency. can do. For example, the length of the time section (e.g., time section 360 of FIG. 3) corresponding to the second driving frequency is the time section (e.g., time section 310 of FIG. 3) corresponding to the first driving frequency. ), and is shorter than the length of the time section 410 in FIG. 4, the probability of seeing a flicker phenomenon while displaying the screen according to the second driving frequency is the probability of displaying the screen according to the first driving frequency. The probability of seeing flicker may be lower than before.

For example, the processor 210 displays the screen according to the first driving frequency by maintaining the driving frequency at the first driving frequency based on the value that is higher than or equal to the reference value. It can be displayed through (110).

Referring again to FIG. 2, the processor 210 refrains from identifying whether the value is lower than the reference value while displaying the screen through the display 110 according to the second driving frequency ( refrain from) It can be bypassed. For example, as shown in FIG. 3, since the length of the time section (e.g., time section 360 in FIG. 3) corresponding to the second driving frequency is relatively short, the processor 210 While the second driving frequency is provided, the identification may not be performed.

As described above, the electronic device 101 generates a current applied to each of the subpixels (or a current applied to a transistor connected to each of the subpixels and used to drive each of the subpixels). Based on the size of , the quality of the screen displayed through the display 110 can be enhanced by adjusting or changing the driving frequency for light emission of the subpixels.

Although the above descriptions and the descriptions below describe operations performed by the processor 210, at least some of the operations may be performed by the display driving circuit 202 within the display 110. For example, when the display driving circuit 202 executes at least some of the above operations, data obtained through the illuminance sensor 230 may be transmitted from the illuminance sensor 230 through the processor 210 to the display driving circuit ( 202) or directly from the illuminance sensor 230 to the display driving circuit 202.

FIG. 5 illustrates an example method of changing the driving frequency according to a value representing the current applied to each of the subpixels while an illuminance lower than the reference illuminance is identified. This method may be executed by the processor 210 of the electronic device 101 shown in FIG. 2 .

Referring to FIG. 5 , in operation 501, the processor 210 may display a screen according to the first driving frequency. For example, the processor 210 may display the screen by emitting the subpixels of the display 110 according to the first driving frequency to reduce power consumed by displaying the screen. there is.

In operation 503, the processor 210 may obtain data representing the illuminance around the electronic device 101 through the illuminance sensor 230 while the screen is displayed according to the first driving frequency. For example, the data may include information about the state of light received by the illuminance sensor 230 from the outside.

At operation 505, processor 210 may identify or determine whether the illuminance indicated by the data is higher than a reference illuminance. For example, a pseudo-reference illuminance can be defined to identify or determine whether the flicker phenomenon illustrated above can be seen while the screen is displayed based on the first driving frequency. For example, the processor 210 executes operation 509 based on the data representing the illuminance that is higher than the reference illuminance, and based on the data representing the illuminance that is less than or equal to the reference illuminance. Thus, operation 507 can be executed.

In operation 507, the processor 210 identifies whether a value representing a current applied to at least some of the subpixels is lower than a reference value under the condition that the illuminance is lower than or equal to the reference illuminance. (or decide) For example, the reference value is that the intensity of light received by the illuminance sensor 230 from the outside is different from the intensity of light received by a part of the display 110 from the outside, so that the screen is displayed based on the first driving frequency. In order to identify (or determine) whether the flicker phenomenon illustrated above can be seen during display, it can be defined. For example, the processor 210 may execute operation 509 based on the value being lower than the reference value, and may execute operation 511 based on the value being higher than or equal to the reference value. .

In operation 509, the processor 210 drives the screen to the second drive frequency by changing the driving frequency to the second driving frequency under the condition that the illuminance is higher than the reference illuminance or the value is lower than the reference value. Depending on the frequency, it can be displayed through the display 110.

For example, the processor 210 adjusts the brightness level of the screen from a first brightness level lower than the reference brightness level to a second brightness higher than the reference brightness level, based on the data indicating the illuminance higher than the reference brightness level. You can change it by level. For example, the processor 210 may change the brightness level to the second brightness level under the condition that a function for identifying (or providing) a brightness level according to the illuminance is activated within the electronic device 101. there is. For example, the processor 210 may display the screen according to the second driving frequency by changing the driving frequency to the second driving frequency based on the second brightness level. For example, the reference brightness level may be a level for brightness provided within a defined mode to display a clearer screen outdoors. However, it is not limited to this. For example, because the higher the brightness level, the higher the probability of seeing a flicker phenomenon, the processor 210 may change the first driving frequency to the second driving frequency. However, it is not limited to this.

For example, the processor 210 may display the screen according to the second driving frequency by changing the first driving frequency to the second driving frequency based on the value that is lower than the reference value. . For example, the processor 210 may change the driving frequency to the second driving frequency in order to reduce a flicker phenomenon that may be seen when displaying the screen according to the first driving frequency.

Although not shown in FIG. 5, the processor 210 refrains from or bypasses identifying (or determining) whether the value is lower than the reference value while the screen is displayed according to the second driving frequency. can do. For example, because the length of the time section corresponding to the second driving frequency is shorter than the length of the time section corresponding to the first driving frequency, the processor 210 identifies (or determines) the value, Comparison of the value with the reference value may be bypassed or avoided. However, it is not limited to this.

In operation 511, the processor 210 displays the screen according to the first driving frequency by maintaining the driving frequency at the first driving frequency under the condition that the value is higher than or equal to the reference value. It can be displayed through the display 110. For example, if the value is higher than or equal to the reference value, a partial area of the display 110 spaced from the illuminance sensor 230 (e.g., area 490 defined through the description of FIG. 4) Since the state of ) corresponds to the illuminance indicated by the data obtained through the illuminance sensor 230, the processor 210 is configured to reduce the consumption of power by the display of the screen. The driving frequency can be maintained at the first driving frequency.

As described above, the electronic device 101 adaptively adjusts the driving frequency based on data acquired through the illuminance sensor 230 and the size of the current applied to each of the subpixels in the display 110. Or you can change it. For example, the electronic device 101 can enhance the quality of the screen displayed through the display 110 by adaptively adjusting the driving frequency.

FIG. 6 illustrates an example method of changing the driving frequency according to a value representing a current applied to each of the subpixels while the screen is displayed at a first brightness level. This method may be executed by the processor 210 of the electronic device 101 shown in FIG. 2 .

Referring to FIG. 6 , in operation 601, the processor 210 may display the screen at a first brightness level according to the first driving frequency. For example, the first brightness level may be identified based on the illuminance identified through the illuminance sensor 230. For example, the processor 210 responds to the illuminance identified through the illuminance sensor 230 based on activation of a function that sets the brightness of the screen to a brightness corresponding to the illuminance around the electronic device 101. The first brightness level may be identified, and the screen may be displayed at the identified first brightness level according to the first driving frequency.

For example, the first driving frequency may be lower than the reference frequency. For example, the reference frequency can be defined to identify whether the time period in which each of the subpixels of the display 110 emits light has a length in which a flicker phenomenon can be seen. For example, the fact that the driving frequency is lower than the reference frequency, such as the first driving frequency, may indicate that the probability of seeing a flicker phenomenon while the screen is displayed according to the first driving frequency is relatively high. However, it is not limited to this.

In operation 603, the processor 210 may identify whether a value representing the current applied to at least some of the subpixels of the display 110 is lower than a reference value. For example, the processor 210 may execute operation 605 based on the value that is lower than the reference value and execute operation 607 based on the value that is higher than or equal to the reference value.

In operation 605, the processor 210 changes the brightness level of the screen to a second brightness level higher than the first brightness level under the condition that the value is lower than the reference value, and drives the subpixels to emit light. By changing the frequency to a second driving frequency higher than the first driving frequency, the screen can be displayed through the display 110 at the second brightness level according to the second driving frequency. For example, the fact that the value is lower than the reference value indicates that, unlike the illuminance identified through the illuminance sensor 230, the intensity of light received from the outside to the at least some of the subpixels is relatively large, The processor 210 may change the first brightness level to the second brightness level. For example, because the intensity of light received from the outside to at least some of the subpixels is relatively high, which indicates that the probability of seeing a flicker phenomenon is relatively high, the processor 210 adjusts the first driving frequency can be changed to the second driving frequency.

For example, the second driving frequency may be higher than the reference frequency. For example, the fact that the driving frequency is higher than or equal to the reference frequency, such as the second driving frequency, means that the probability of seeing a flicker phenomenon while the screen is displayed according to the second driving frequency is relatively low. It can be expressed. However, it is not limited to this.

Although not shown in FIG. 6 , the processor 210 may refrain from or bypass identifying whether the value is lower than the reference value while the screen is displayed according to the second driving frequency. For example, because the length of the time section corresponding to the second driving frequency is shorter than the length of the time section corresponding to the first driving frequency, the processor 210 identifies the value, and combines the value with the reference. Comparing values can be bypassed or avoided. However, it is not limited to this.

In operation 607, the processor 210 maintains the brightness level of the screen at the first brightness level and adjusts the driving frequency to the first driving frequency under the condition that the value is higher than or equal to the reference value. By maintaining , the screen can be displayed through the display 110 at the first brightness level and according to the first driving frequency. For example, the value being higher than or equal to the reference value means that the intensity or state of light received from the outside to the at least some of the subpixels corresponds to the illuminance identified through the illuminance sensor 230. Since , the processor 210 can maintain the first brightness level and the first driving frequency.
