Description

Electronic device including display and method of operating same

Embodiments of the present disclosure relate to an electronic device including a display and a method of operating the same.

Displays in electronic devices are a core technology of the information and communication era, and are developing to become thinner, lighter, more portable, and have higher performance. For example, organic light-emitting diode (OLED) displays are attracting attention as flat panel display devices that can reduce the weight and volume, which are disadvantages of cathode ray tubes (CRTs). OLED displays can display images by arranging multiple pixels in a matrix form. Each pixel may include a light-emitting device, a plurality of driving devices (eg, thin film transistors (TFTs)) that independently drive the light-emitting device, and at least one storage capacitor.

The contents described above are provided only as background information to help understand the embodiments of the present disclosure. No decision has been made, and no claim has been made, as to whether any of the above may apply as prior art in connection with this disclosure.

Development is underway to increase the refresh rate (e.g., driving frequency) of the display. As the refresh rate of the display increases, the clarity of the displayed image increases, and more natural video expression may be possible. The power consumption of an electronic device may vary depending on the refresh rate of the display. As the refresh rate of the display increases, the power consumption of the electronic device may increase. When driving the display, the maximum frequency and driving frequency can be set. The maximum frequency of the display is set to 120Hz, and the driving frequency can be set to 120Hz, 60Hz, 30Hz, or 10Hz. The power consumption of an electronic device is affected by the maximum frequency of the display. Lowering the maximum frequency of the display can reduce the power consumption of the electronic device. The first frame may operate at a first maximum (max 1) frequency, and the second frame may operate at a second maximum (max 2) frequency lower than the first maximum (max 1) frequency. When changing the maximum frequency of the display, the 1H period and the speed (e.g. slope) of the EM scan signal change, and the difference in the instantaneous emission area causes flicker (e.g. Flickering) may occur.

In one embodiment of the present disclosure, when the maximum (max) frequency of the display is changed, an intermediate operating frequency (e.g., temporary operation) is provided between the first frame operating at the first operating frequency and the second frame operating at the second operating frequency. Improve the flicker (e.g. flicker) phenomenon by placing intermediate frames (e.g. temporary frames, bridge frames, connection frames, seamless frames) that operate at a frequency, bridge operation frequency, connection operation frequency, seamless operation frequency ( or prevention) and an operating method thereof can be provided.

At least one intermediate frame may be placed between a first frame operating at the first operating frequency and a second frame operating at the second operating frequency. It may be configured to operate at an intermediate operating frequency between the first operating frequency and the second operating frequency in the at least one intermediate frame.

Additionally, the difference between the light emission area of the middle frame and the second frame can be reduced. In this way, by reducing the difference in light emitting area between frames, it is possible to reduce (or prevent) the flicker phenomenon from occurring when the operating mode of the display is changed (e.g., the maximum frequency is changed).

An electronic device and a method of operating the same according to an embodiment of the present disclosure adjust the number of EM scan signals in the middle frame of the middle mode when changing the operation mode of the display from the first operation mode to the second operation mode. By increasing the light emitting area, the difference between the light emitting area of the first frame and the middle frame can be reduced. Additionally, the difference between the light emission area of the middle frame and the second frame can be reduced. In this way, by reducing the difference in light emitting area between frames, it is possible to reduce (or prevent) the flicker phenomenon from occurring when the operating mode of the display is changed (e.g., the maximum frequency is changed).

When changing the operation mode of the display 410, to prevent flicker (flickering) phenomenon from occurring, the processor 120 sets an intermediate operation mode ( The DDI 430 may be controlled to drive the display 410 in 930) (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode). When changing the operation mode of the display 410 based on the control of the processor 120, the DDI 430 sets an intermediate operation mode 930 (e.g., between the first operation mode 910 and the second operation mode 920). The display 410 can be operated in a temporary operation mode, bridge operation mode, connected operation mode, and seamless operation mode).

As an example, the DDI 430 may operate the display 410 at a first operating frequency (e.g., a maximum frequency of 120 Hz and an operating frequency of 60 Hz) in the first operating mode 910.

As an example, the DDI 430 may operate the display 410 at a second operating frequency (e.g., a maximum frequency of 60 Hz and an operating frequency of 60 Hz) in the second operating mode 920.

As an example, DDI 430 can be configured to operate at an intermediate operating frequency (e.g., any frequency between 60 Hz and 120 Hz) in an intermediate operating mode 930 (e.g., transient operating mode, bridged operating mode, connected operating mode, seamless operating mode). The display 410 can be operated.

As an example, in an intermediate operation mode 930 (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode), the maximum frequency at which the display 410 operates is set to any frequency between 60 Hz and 120 Hz. And the driving frequency can be set to 60Hz.

FIG. 10 is a diagram illustrating a change in a light emitting area when the operating frequency of a display changes from a first operating frequency to a second operating frequency as a method of operating an electronic device according to an embodiment of the present disclosure. 11 is a method of operating an electronic device according to an embodiment of the present disclosure. When the operating frequency of a display is changed, an intermediate frame is displayed between a first frame operating at a first operating frequency and a second frame operating at a second operating frequency. This is a diagram showing the change in light emitting area when an intermediate frame operating at the operating frequency is included.

Referring to FIGS. 9 to 11 , according to one embodiment, when changing from the first operation mode 910 to the second operation mode 920, the processor (e.g., processor 120 of FIG. 1) enters the intermediate operation mode. At 930, the DDI (eg, DDI 430 in FIGS. 4 and 5) can be controlled to drive the display 410.

For example, when the operation mode of the display 410 is changed from the first operation mode 910 to the intermediate operation mode 930 (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode), DDI ( The maximum frequency of the display 410 can be lowered by lowering the clock (CLK) frequency of the oscillator (430). By lowering the maximum frequency of the display 410, the 1H period and the speed (eg, slope) of the EM scan signal may be changed.

For example, when the operation mode of the display 410 is changed from the intermediate operation mode (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode) to the second operation mode 920, the DDI 430 By lowering the clock (CLK) frequency of the oscillator, the maximum (max) frequency of the display 410 can be lowered. By lowering the maximum frequency of the display 410, the 1H period and the speed (eg, slope) of the EM scan signal may be changed.

According to one embodiment, the processor 120 operates in the middle between the first frame 1010 operating at the first operating frequency according to the first operating mode 910 and the second frame 1020 operating at the second operating frequency. An intermediate frame 1130 (e.g., temporary frame, bridge frame, connected frame, seamless frame) operating at an operating frequency (e.g., temporary operating frequency, bridge operating frequency, connected operating frequency, seamless operating frequency) may be placed.

For example, the first operating frequency according to the first operating mode 910 of the display 410 may have a maximum frequency set to 120 Hz and a driving frequency set to 60 Hz. In the first operation mode 910, one horizontal (1H) period 911 of the frame may be 3.52 μs at a maximum frequency of 120 Hz.

For example, the maximum (max) frequency of the second operating frequency according to the second operating mode 920 of the display 410 may be set to 60 Hz, and the driving frequency may be set to 60 Hz. In the second operation mode 920, one horizontal (1H) period 921 of the frame may be 7.04 μs in accordance with the maximum frequency of 60Hz.

As an example, the intermediate operating frequency according to the intermediate operation mode 930 (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode) of the display 410 is a frequency value between 60 Hz and 120 Hz, with a maximum frequency. is set, and the driving frequency can be set to 60Hz. In intermediate operation modes 930 (e.g., transient operation mode, bridge operation mode, connected operation mode, seamless operation mode), 1 horizontal (1H) period of the frame is adjusted to the maximum (max) frequency (e.g., 70-110 Hz). 931) can be a value between 3.52 ㎲ and 7.04 ㎲ (e.g. 4.45 ㎲).

According to one embodiment, the DDI 430 performs an intermediate operation according to an intermediate operation mode 930 (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode) based on the control of the processor 120. Frequencies (e.g. transient operating frequency, bridge operating frequency, connected operating frequency, seamless operating frequency) can be generated (e.g. a maximum frequency of any value between 60 Hz and 120 Hz). As an example, the DDI 430 increases the horizontal front porch (HFP) and reduces the vertical front porch (VFP) (e.g., from 2380H to 1388H) to increase the intermediate operating frequency (e.g., temporary operating frequency, bridge operating frequency, and connection operating frequency). frequency, seamless operating frequency) (e.g., a maximum frequency of any value between 60 Hz and 120 Hz).

As an example, by increasing the HFP and decreasing the VFP in the DDI 430, the intermediate operating frequency is generated, so that one horizontal (1H) period of the intermediate frame 1130 is divided into the first frame 1010 and the second frame 1020. It is different from the 1 horizontal (1H) period of. As the 1 horizontal (1H) period of the middle frame 1130 varies, the speed (e.g., slope) of the EM scan signal of the middle frame 1130 varies between the first frame 1010 and the second frame 1020. It has a value between the speed (e.g. slope) of the emission scan (EM scan) signal. The difference in the light emitting area between the first frame 1010 and the second frame 1020 can be reduced to the light emitting area of the middle frame 1130, thereby reducing (or preventing) the flicker phenomenon from occurring. You can.

As an example, the intermediate operating frequency (e.g., temporary operating frequency, bridge operating frequency, connected operating frequency, seamless operation) according to the intermediate operating mode 930 (e.g., temporary operating mode, bridge operating mode, connected operating mode, seamless operating mode). One or more intermediate frames 1130 operating at a frequency (e.g., a maximum frequency of any value between 60 Hz and 120 Hz) may be disposed.

For example, when a plurality of intermediate frames 1130 are disposed between the first frame 1010 of the first operation mode 910 and the second frame 1020 of the second operation mode 920, the plurality of intermediate frames The intermediate operating frequencies of each of (1130) can be generated to be the same. When switching to an intermediate operation mode 930 (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode), a plurality of intermediate frames 1130 may be disposed.

For example, when a plurality of intermediate frames 1130 are disposed between the first frame 1010 of the first operation mode 910 and the second frame 1020 of the second operation mode 920, the plurality of intermediate frames The intermediate operating frequencies of each of (1130) may be generated differently. When switching to an intermediate operation mode 930 (e.g., temporary operation mode, bridge operation mode, connected operation mode, seamless operation mode), a plurality of intermediate frames 1130 may be disposed.

According to one embodiment, the DDI 430 operates at an operating frequency (e.g., temporary operating frequency, bridge operating frequency) in an intermediate operating mode 930 (e.g., temporary operating mode, bridge operating mode, connected operating mode, seamless operating mode). , connected operating frequency, seamless operating frequency) (e.g., maximum frequency of any value between 60Hz and 120Hz). As an example, the DDI 430 has a gamma value applied to the first operation mode 910, a gamma value applied to the second operation mode 920, and an intermediate operation mode 930 (e.g., temporary operation mode, bridge The gamma value applied to the operation mode, connected operation mode, and seamless operation mode) can be changed differently.

As shown in FIG. 10, when the display 410 operates at a first operating frequency according to the first operating mode 910 and then operates at a second operating frequency according to the second operating mode 920, the first operating mode 920 When moving from the first frame 1010 according to 910 to the second frame 1020 according to the second viewing mode 920, there is a momentary difference in the light emitting area 1030, causing a flicker phenomenon. It can happen.

As shown in FIG. 11, an intermediate operation mode 930 (e.g., a temporary operation mode) is formed between the first frame 1010 of the first operation mode 910 and the second frame 1020 of the second operation mode 920. mode, bridge operation mode, connection operation mode, seamless operation mode), the difference in the light emitting area 1140 when moving from the first frame 1010 to the middle frame 1130 is disposed (or inserted). You can reduce (or prevent) the flicker phenomenon from occurring. Additionally, the occurrence of flicker (flickering) can be reduced (or prevented) by reducing the difference in the light emitting area 1150 when moving from the middle frame 1130 to the second frame 1020.

When changing the operating mode of the display 410, the first frame 1010 operates at a first operating frequency according to the first operating mode 910 and the first frame 1010 operates at a second operating frequency according to the second operating mode 920. Between the second frame 1020, the intermediate operating frequency (e.g., temporary operating frequency, bridge operating frequency, Reduce (or prevent) the occurrence of flicker by placing an intermediate frame 1130 that operates at a connected operating frequency, seamless operating frequency (e.g., a maximum frequency of any value between 60 Hz and 120 Hz). )can do.

electronic devices

101, 200, and 300 can be reduced. By applying the above intermediate frame and intermediate operating frequency in the change situation of several operating modes with different 1H (1H) periods, even when high frequencies are not required, such as specific applications or still screens, such as 60HS → 60NS, 10HS → 10NS. Operating frequency can be replaced. Through this, power consumption of the

electronic devices

101, 200, and 300 can be reduced.

(For example, DDI 430 in FIGS. 4 and 5) can be controlled.

According to one embodiment, the DDI 430 changes the operation mode of the display (e.g., the display 410 of FIG. 9) from the first operation mode 910 to the second operation mode ( When changing to 920), the display 410 can be operated by changing the number of EM scan signals and/or the EM off time (AOR: AID off ratio) 1240.

For example, when the DDI 430 changes from the first operation mode 910 to the second operation mode 920, the emission (EM) off time (AOR) is changed in the middle frame 1130 of the intermediate mode 930. : By reducing the AID off ratio (1240), the difference between the light emitting area of the first frame (1010) and the light emitting area of the middle frame (1130) can be reduced. Additionally, the difference between the light emission area of the middle frame 1130 and the second frame 1020 can be reduced.

For example, when changing from the first operation mode 910 to the second operation mode 920, the DDI 430 increases the number of EM scan signals in the middle frame 1130 of the middle mode 930. This can reduce the difference between the light emitting area of the first frame 1010 and the light emitting area of the middle frame 1130. Additionally, the difference between the light emission area of the middle frame 1130 and the second frame 1020 can be reduced.
