The above and other aspects, features and advantages of certain embodiments of the present disclosure will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Referring to
The processor 110 may include various processing circuitry and may include at least a portion of a processor 920 of
The display 115 may include at least a portion of a display module 960 of
The display driver circuitry 120 may include at least a portion of a DDI 1030 of
The display panel 140 may include at least a portion of a display 1010 of
Each of the processor 110, the interface 112 for the image transmission, and the display driver circuitry 120 may be configured for a first mode and/or a second mode.
The first mode may indicate a mode of executing the image transmission based on a timing identified by the processor 110 (or timing for the processor 110). For example, the first mode may be a video mode of a mobile industry processor interface (MIPI) display serial interface (DSI) or a mode similar to the video mode. As a non-limiting example, the first mode may be partially different from the video mode. As a non-limiting example, it may be optional to store, in the memory 130, an image received from the processor 110 through the interface 112 according to the image transmission executed based on the first mode. For example, storing the image in the memory 130 in the first mode may be executed to reduce occurrence of afterimages on the display panel 140 or occurrence of blinking on the display panel 140. As a non-limiting example, a throughput of the image transmission executed based on the first mode may be less than a throughput of the image transmission executed based on the second mode. As a non-limiting example, a vertical sync start (VSS) packet may be provided to the display driver circuitry 120 to indicate the image transmission executed for the first mode before the image transmission executed for the first mode.
The second mode may indicate a mode of executing an image transmission from the processor 110 to the display driver circuitry 120 through the interface 112 based on a timing identified by the display driver circuitry 120 (or timing for the display driver circuitry 120). For example, the second mode may be a command mode of MIPI DSI. As a non-limiting example, it may be mandatory to store, in the memory 130, an image received from the processor 110 through the interface 112 according to the image transmission executed based on the second mode. As a non-limiting example, a throughput of the image transmission executed based on the second mode may be greater than a throughput of the image transmission executed based on the first mode. For example, the image transmission executed based on the second mode may be a data burst transmission, unlike the image transmission executed based on the first mode. As a non-limiting example, the second mode may be a mode for always on display (AOD). As a non-limiting example, a 2ch command may be provided to the display driver circuitry 120 to indicate the image transmission executed for the second mode before the image transmission executed for the second mode.
As a non-limiting example, the first mode may be changed to the second mode, and the second mode may be changed to the first mode.
For example, the display driver circuitry 120 may re-display, based on scanning an image stored in the memory 130, the image on the display panel 140. For example, the re-display of the image may be executed to maintain display on the display panel 140. For example, the re-display of the image may be executed to reduce occurrence of an afterimage on the display panel 140. For example, the re-display of the image may be executed to reduce occurrence of blinking on the display panel 140.
For example, the re-display of the image executed by the display driver circuitry 120 may be transparent to the processor 110. For example, since the re-display of the image is executed while the image transmission from the processor 110 to the display driver circuitry 120 is not being executed, the processor 110 may not recognize or identify the re-display of the image. As a non-limiting example, the processor 110 may be in a sleep state different from a wake-up state while the re-display of the image is being executed.
The processor 110 may provide a command to the display driver circuitry 120 to control display on the display panel 140. For example, the display driver circuitry 120 may execute display on the display panel 140, based on the command obtained from the processor 110.
For example, the processor 110 may provide the display driver circuitry 120 with at least one command for display on the display panel 140. For example, the at least one command may be provided for an image to be transmitted from the processor 110 to the display driver circuitry 120. For example, the at least one command may be applied to at least one targeted image. For example, the at least one targeted image may include the image to be transmitted from the processor 110 to the display driver circuitry 120 and/or at least one image to be transmitted to the display driver circuitry 120 after the image is transmitted to the display driver circuitry 120. For example, when the at least one command is applied to at least another image that is distinct from (or different from) the at least one targeted image, malfunction may occur within the display 115 or a quality of a service provided through the display 115 may be reduced. For example, it may be mandatory to transmit to the display driver circuitry 120 a targeted image to which the at least one command will be applied after the at least one command is transmitted.
For example, the processor 110 may provide the display driver circuitry 120 with at least another command for display on the display panel 140. For example, the at least another command may be provided regardless of the at least one targeted image (or independently of the at least one targeted image). For example, the at least another command may be applied to any image. For example, the at least another command is not targeted to a specific image, so even if the at least another command is applied to an arbitrary image, the malfunction and/or a decrease in the quality of the service may not be caused. For example, transmitting an image to the display driver circuitry 120 after the at least another command is transmitted may be optional.
As a non-limiting example, the at least one command may be used to change a refresh rate. For example, the at least one command may indicate activating of the memory 130 (or deactivating of the memory 130), a target refresh rate, a maximum refresh rate, a minimum refresh rate, and/or a timing of scanning for display on the display panel 140.
As a non-limiting example, the at least one command may be used to change the first mode to the second mode. For example, the at least one command may indicate a change (or transition) from the first mode to the second mode, a target refresh rate provided in the second mode, a maximum refresh rate provided in the second mode, a minimum refresh rate provided in the second mode, and/or a timing of scanning for display on the display panel 140 in the second mode.
As a non-limiting example, the at least one command may be used to change the second mode to the first mode. For example, the at least one command may indicate a change (or transition) from the second mode to the first mode, a target refresh rate provided in the first mode, a maximum refresh rate provided in the first mode, and/or a timing of scanning for display on the display panel 140 in the first mode.
As a non-limiting example, the at least one command may be used to change the first mode to the second mode for low power (e.g., hybrid low power mode (HLPM)). For example, the at least one command indicates a target refresh rate provided in the second mode for the low power, a maximum refresh rate provided in the second mode for the low power, and/or a minimum refresh rate provided in the second mode for the low power.
As a non-limiting example, the at least one command may be used to change the second mode for the low power to the first mode. For example, the at least one command may indicate a target refresh rate in the first mode changed from the second mode for the low power, a maximum refresh rate in the first mode changed from the second mode for the low power, and/or a minimum refresh rate in the first mode changed from the second mode for the low power.
As a non-limiting example, the at least another command may be used to change a brightness level of an image displayed on the display panel 140. For example, the at least another command may indicate a target brightness level of an image displayed on the display panel 140 when changing a refresh rate, changing the first mode to the second mode, or changing the second mode to the first mode. As a non-limiting example, the at least another command may be used to change a gamma curve used for display on the display panel 140. As a non-limiting example, the at least another command may be used to cancel or delay the at least one command. For example, the at least another command may be used to cancel or delay executing operations for re-display of an image based on the at least one command. For example, the at least another command may be used to cancel or delay executing operations to reduce occurrence of an afterimage on the display panel 140 based on the at least one command. For example, the at least another command may be used to cancel or delay use of at least one intermediate frequency for changing from a first frequency to a second frequency based on the at least one command. For example, the at least another command may be used to cancel or delay executing operations to reduce occurrence of blinking on the display panel 140 based on the at least one command. For example, the at least another command may be used to cancel or delay changing a refresh rate on the display panel 140 to a minimum refresh rate based on the at least one command. For example, the at least another command may be used to change a location or an image to which the at least one command will be applied. However, the disclosure is not limited thereto.
As described above, since the re-display of the image executed by the display driver circuitry 120 is transparent to the processor 110, the at least one command may be provided from the processor 110 to the display driver circuitry 120 while the re-display of the image is being executed. For example, the at least one command provided from the processor 110 to the display driver circuitry 120 while the re-display of the image is being executed may be applied to the image, which is different from a targeted image related to the at least one command. For example, since applying the at least one command to the image causes a decrease in the quality of the service and/or the malfunction, the processor 110 may provide the display driver circuitry 120 with the at least one command, in another time interval different from (or distinct from) a time interval during which the re-display of the image may be executed.
A method of providing the at least one command and a method of providing the at least another command may be described in greater detail below with reference to
Referring to
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command before a targeted image to which the at least one command is applied is transmitted to the display driver circuitry 120.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command to be applied to a targeted image, in a time interval in a vertical front porch (or extended vertical front porch) of a second vertical synchronization signal for the processor 110, wherein the time interval in the vertical front porch (or extended vertical front porch) of the second vertical synchronization signal for the processor 110 is before a reference time 201 from a start timing of a first vertical synchronization signal for the processor 110 used to transmit the targeted image to the display driver circuitry 120. For example, the reference time 201 may be defined, configured, or set for a time consumed to apply the at least one command to the targeted image.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command for the first targeted image, in a time interval 205 being before a reference time 201 from a start timing 204 of a vertical synchronization signal 203 used to transmit a first targeted image to the display driver circuitry 120, as indicated by arrow 202. For example, the time interval 205 may be included in a vertical front porch 207 (e.g., vertical front porch (VFP)) of a vertical synchronization signal 206 being before the vertical synchronization signal 203. For example, the time interval 205 may have a reference length. For example, the reference length may be identical to a length obtained by subtracting the reference time 201 from a length of the vertical front porch 207, as illustrated in
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command in the time interval 205, and then transmit the first targeted image to the display driver circuitry 120 based on the start timing 204. For example, the processor 110 may provide the display driver circuitry 120 with the at least one of the commands in the time interval 205, transmit a vertical sync start (VSS) packet indicating transmission of the first targeted image to the display driver circuitry 120 at the start timing 204, and transmit the first targeted image to the display driver circuitry 120 at a start timing 209 of a vertical active 208 of the vertical synchronization signal 203 (or an end timing 209 of a vertical back porch (VBP)). For example, the display driver circuitry 120 may display the first targeted image on the display panel 140, based on applying the at least one command obtained in the time interval 205 to the first targeted image received at the start timing 209.
For example, the processor 110 may extend the vertical synchronization signal 203 while a newly obtained image after transmitting the first targeted image based on the start timing 204 is not present. For example, until a new image is obtained, the processor 110 may obtain an extended vertical front porch (extended VFP) 212 of the vertical synchronization signal 203 being initiated from an end timing 211 of a vertical front porch (VFP) 210 of the vertical synchronization signal 203. For example, a length of the extended vertical front porch 212 may be a multiple of the emission period 200.
As a non-limiting example, the display driver circuitry 120 may store the first targeted image received from the start timing 209 in the memory 130. For example, since the extended vertical front porch 212 includes the emission periods 200 (e.g., two emission periods 200), the display driver circuitry 120 may re-display the first targeted image by scanning the first targeted image stored in the memory 130 within the extended vertical front porch 212.
For example, since the re-display of the first targeted image is executed within the extended vertical front porch 212 in which an image transmission from the processor 110 to the display driver circuitry 120 is not executed, the re-display of the first targeted image may be transparent to the processor 110.
For example, the processor 110 may obtain a second targeted image (e.g., an image to be displayed based on a vertical synchronization signal 223) and identify the at least one command for the second targeted image. For example, since the re-display of the first targeted image is transparent to the processor 110, the at least one command for the second targeted image when transmitted from the processor 110 to the display driver circuitry 120 may be applied to the first targeted image, in a portion of a time interval 213 (e.g., a time interval from the start timing 211 of the emission period 200) within the vertical front porch 212 in which the at least one command for the second targeted image is extended and/or a time interval 214 (e.g., a time interval from a start timing 215 of the emission period 200) within the extended vertical front porch 212. Since applying the at least one command for the second targeted image to the first targeted image may cause a decrease in the quality of the service or the malfunction, the processor 110 may refrain from, delay, or bypass providing the display driver circuitry 120 with the at least one command, in at least one time interval (e.g., a portion of the time interval 213 and the time interval 214) within the extended vertical front porch 212 in which the re-display of the first targeted image may be executed.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command in a time interval 225 within the extended vertical front porch 212, in order to apply the at least one command to the second targeted image among the first targeted image stored in the memory 130 and the second targeted image to be transmitted to the display driver circuitry 120 as indicated by arrow 222. For example, the time interval 225 may be a time interval within the extended vertical front porch 212 in which the re-display of the first targeted image cannot be executed. For example, the time interval 225 may be after scanning of the first targeted image in the memory 130 for the re-display of the first targeted image is terminated. For example, the time interval 225 may be before a reference time 201 from a start timing 224 of the vertical synchronization signal 223 for the processor 110 used to transmit the second targeted image. For example, the time interval 225 may be between an end timing of scanning of the first targeted image and a timing before the reference time 201 from the start timing 224. For example, a length of the time interval 225 may correspond to a length of the time interval 205.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command in the time interval 225, and then transmit the second targeted image to the display driver circuitry 120 based on the start timing 224. For example, the processor 110 may provide the display driver circuitry 120 with the at least one command in the time interval 225, transmit a VSS packet indicating a transmission of the second targeted image to the display driver circuitry 120 at the start timing 224, and transmit the second targeted image to the display driver circuitry 120 at a start timing 229 of a vertical active 228 of the vertical synchronization signal 223. For example, the display driver circuitry 120 may display the second targeted image on the display panel 140, based on applying the at least one command obtained in the time interval 225 to the second targeted image received at the start timing 229.
For example, the processor 110 may extend the vertical synchronization signal 223 while a newly obtained image after transmitting the second targeted image based on the start timing 224 is not present. For example, until a new image is obtained, the processor 110 may obtain an extended vertical front porch 232 of the vertical synchronization signal 223 being initiated from an end timing 231 of a vertical front porch 230 of the vertical synchronization signal 223. Although not explicitly illustrated in
For example, the processor 110 may provide the display driver circuitry 120 with the at least another command that does not have a targeted image (or may be applied to any image). For example, the at least another command may be provided to the display driver circuitry 120 within a vertical front porch (or extended vertical front porch) of a vertical synchronization signal for the processor 110. For example, the at least another command may be provided to the display driver circuitry 120, within a time interval being before a reference time 201 from an end timing of the vertical front porch. For example, since the at least another command is independent of an image transmission, the at least another command may be provided to the display driver circuitry 120 in a time interval being before the reference time 201 from an end timing of the vertical front porch of the vertical synchronization signal being before the extended vertical front porch of the vertical synchronization signal. For example, the amount of time resources used to provide the at least another command may be greater than the amount of time resources used to provide the at least one command.
For example, the processor 110 may provide the display driver circuitry 120 with the at least another command, within the time interval 205 being before a reference time 201 from a start timing 204 of a vertical synchronization signal 203. For example, the processor 110 may provide the at least another command to the display driver circuitry 120, in a time interval 245 being before a reference time 201 from an end timing 211 of a vertical front porch 210 being before an extended vertical front porch 212. For example, the processor 110 may provide the display driver circuitry 120 with the at least another command, in a time interval 213 being before a reference time 201 from a start timing 215. For example, the processor 110 may provide the display driver circuitry 120 with the at least another command, in a time interval 246 being before a reference time 201 from a start timing 224. For example, a portion of the time interval 246 may overlap the time interval 225 capable of providing the at least one command. For example, the processor 110 may provide the at least another command to the display driver circuitry 120, in a time interval 247 being before a reference time 201 from an end timing 231 of a vertical front porch 230 being before an extended vertical front porch 232. For example, the processor 110 may provide the display driver circuitry 120 with the at least another command in a time interval 248. For example, the time interval 248 may be within a portion of the extended vertical front porch 232.
As described above, the processor 110 may execute transmitting the at least one command to the display driver circuitry 120, before an image to which the at least one command will be applied is transmitted. For example, the electronic device 100 including the processor 110 may provide an enhanced service through the display 115.
Referring to
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command, before a targeted image to which the at least one command will be applied is transmitted to the display driver circuitry 120.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command to be applied to the targeted image, in a time interval within a vertical front porch (or extended vertical front porch) of a second vertical synchronization signal for the processor 110 that is before a reference time 201 from a start timing of a first vertical synchronization signal for the processor 110 used to transmit the targeted image to the display driver circuitry 120. For example, the reference time 201 may be defined, configured, or set for a time consumed to apply the at least one command to the targeted image. As a non-limiting example, a time interval that provides the at least one command while the image transmission is executed based on the vertical synchronization signal for the processor 110 may correspond to a time interval that provides the at least one command while the image transmission is executed based on the emission synchronization signal for the processor 110.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command for the first targeted image, in a time interval 305 being before a reference time 201 from a start timing 304 of a vertical synchronization signal 303 used to transmit a first targeted image to the display driver circuitry 120, as indicated by arrow 302. For example, the time interval 305 may be included within a vertical front porch (e.g., VFP) 307 of a vertical synchronization signal 306 being before the vertical synchronization signal 303. As a non-limiting example, a length of the time interval 305 may correspond to a length of the time interval 205 of
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command within the time interval 305, and then transmit the first targeted image to the display driver circuitry 120 based on the start timing 304. For example, the processor 110 may provide the at least one command to the display driver circuitry 120 within the time interval 305, transmit a vertical sync start (VSS) packet indicating transmission of the first targeted image to the display driver circuitry 120 at the start timing 304, and transmit the first targeted image to the display driver circuitry 120 at a start timing 309 of a vertical active 308 of the vertical synchronization signal 303 (or an end timing 309 of a vertical back porch (VBP)). For example, the display driver circuitry 120 may display the first targeted image on the display panel 140, based on applying the at least one command obtained within the time interval 305 to the first targeted image received at the start timing 309.
For example, the processor 110 may extend the vertical synchronization signal 303, while a newly obtained image after transmitting the first targeted image based on the start timing 304 is not present. For example, until a new image is obtained, the processor 110 may obtain an extended vertical front porch (extended VFP) 312 of the vertical synchronization signal 303 being initiated from an end timing 311 of a vertical front porch (VFP) 310 of the vertical synchronization signal 303.
As a non-limiting example, the display driver circuitry 120 may store the first targeted image received from the start timing 309 in the memory 130. For example, the display driver circuitry 120 may re-display the first targeted image by scanning the first targeted image stored in the memory 130 in the extended vertical front porch 312.
For example, since the re-display of the first targeted image is executed in the extended vertical front porch 312 in which an image transmission from the processor 110 to the display driver circuitry 120 is not executed, the re-display of the first targeted image may be transparent to the processor 110.
For example, the processor 110 may obtain a second targeted image (e.g., an image to be displayed based on a vertical synchronization signal 323) and identify the at least one command for the second targeted image. For example, since the re-display of the first targeted image is transparent to the processor 110, the at least one command for the second targeted image when transmitted from the processor 110 to the display driver circuitry 120 may be applied to the first targeted image, in a time interval 314 within the vertical front porch 312 in which the at least one command for the second targeted image is extended. Since applying the at least one command for the second targeted image to the first targeted image may cause a decrease in the quality of the service or the malfunction, the processor 110 may refrain from, delay, or bypass providing the at least one command to the display driver circuitry 120 in a time interval 314 within the extended vertical front porch 312 during which the re-display of the first targeted image may be executed.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command in a time interval 325 within the extended vertical front porch 312, in order to apply the at least one command to the second targeted image among the first targeted image stored in the memory 130 and the second targeted image to be transmitted to the display driver circuitry 120, as indicated by arrow 322. For example, the time interval 325 may be a time interval within extended vertical front porch 312 in which the re-display of the first targeted image cannot be executed. For example, the time interval 325 may be after scanning of the first targeted image in the memory 130 for the re-display of the first targeted image is terminated. For example, the time interval 325 may before a reference time 201 from a start timing 324 of a vertical synchronization signal 323 for the processor 110 used to transmit the second targeted image. For example, the time interval 325 may be between an end timing of scanning of the first targeted image and a timing before a reference time 201 from the start timing 324. For example, a length of the time interval 325 may correspond to a length of the time interval 305.
For example, the processor 110 may provide the display driver circuitry 120 with the at least one command in the time interval 325, and then transmit the second targeted image to the display driver circuitry 120 based on the start timing 324. For example, the processor 110 may provide the at least one command in the time interval 325 to the display driver circuitry 120, transmit a VSS packet indicating a transmission of the second targeted image to the display driver circuitry 120 at the start timing 324, and transmit the second targeted image to the display driver circuitry 120 at a start timing 329 of a vertical active 328 of the vertical synchronization signal 323. For example, the display driver circuitry 120 may display the second targeted image on the display panel 140, based on applying the at least one command obtained in the time interval 325 to the second targeted image received at the start timing 329.
For example, the processor 110 may extend the vertical synchronization signal 323 while a newly obtained image after transmitting the second targeted image based on the start timing 324 is not present. For example, until a new image is obtained, the processor 110 may obtain an extended vertical front porch 332 of the vertical synchronization signal 323 being initiated from an end timing 331 of a vertical front porch 330 of the vertical synchronization signal 323.
For example, the processor 110 may provide the display driver circuitry 120 with the at least another command that does not have a targeted image (or may be applied to any image). For example, the at least another command may be provided to the display driver circuitry 120 within a vertical front porch (or extended vertical front porch) of a vertical synchronization signal for the processor 110. For example, the at least another command may be provided to the display driver circuitry 120 within a time interval being before a reference time 201 from an end timing of the vertical front porch. For example, since the at least another command is independent of image transmission, the at least another command may be provided to the display driver circuitry 120 in a time interval being before the reference time 201 from an end timing of the vertical front porch of the vertical synchronization signal being before the extended vertical front porch of the vertical synchronization signal. For example, the amount of time resources used to provide the at least another command may be greater than the amount of time resources used to provide the at least one command.
For example, the processor 110 may provide the display driver circuitry 120 with the at least another command, within the time interval 305 being before a reference time 201 from a start timing 304 of a vertical synchronization signal 303. For example, the processor 110 may provide the at least another command to the display driver circuitry 120, in a time interval 345 being before a reference time 201 from an end timing 311 of a vertical front porch 310 being before an extended vertical front porch 312. For example, the processor 110 may provide the display driver circuitry 120 with the at least another command, in a time interval 346 being before a reference time 201 from a start timing 324. For example, since the display driver circuitry 120 executes display on the display panel 140 based on the vertical synchronization signal, a length of the time interval 314 capable of providing the at least another command within the extended vertical front porch 312 may be longer than a length of a time interval capable of providing the at least one command within the extended vertical front porch 212 of

For example, the processor 110 may transmit a packet 408 including the first targeted image to the display driver circuitry 120 according to the start timing 407, based on the timing signal 400 obtained at the timing 404. For example, the display driver circuitry 120 may store the first targeted image within the packet 408 in the memory 130 and display the first targeted image on the display panel 140 by scanning the first targeted image in the memory 130. For example, a 2ch command may be received from the processor 110 before the first targeted image is received.
For example, the display driver circuitry 120 may provide the processor 110 with the timing signal 400 at a timing 414. For example, since a new image obtained by the processor 110 does not exist, executing an image transmission based on the timing signal 400 obtained at the timing 414 may be bypassed or skipped. For example, the processor 110 may extend the vertical synchronization signal 406 until the timing signal 400 is obtained again from the display driver circuitry 120 after a new image is obtained.

For example, the processor 110 may provide the display driver circuitry 120 with the at least another command that does not have a targeted image from a timing at which a reception of a packet including an image is terminated (or completed). As a non-limiting example, the at least another command may be provided in a portion of a vertical active of a vertical synchronization signal for the processor 110 and/or at least a portion of a vertical front porch (and/or extended vertical front porch).
