Description

Method, device and chip for reducing power consumption of display panel module Technical Field

[0001] The present invention relates to the field of circuit technology, and in particular to a method, device, and chip for reducing power consumption of a display panel module. Background Art

[0002] The largest component of a display driver IC's (Integrated Circuit Chip) power consumption comes from the DC power consumed by the source opamp (source operational amplifier). For example, an FHD (Full High Definition) TDDI (Touch and Display Driver Integration) chip has 1080 channels, each utilizing a source opamp, which accounts for over half of the individual power consumption. To reduce IC power consumption, existing approaches typically reduce the power consumption of the source opamp, for example by reducing or disabling some or all of the opamp's paths to reduce overall power consumption. However, this approach can slow the opamp's speed, impacting its ability to charge and discharge the panel.

[0041] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] The structure of the existing display panel module is first briefly described below.

[0043] Taking a commonly used 720x1280 resolution LCD panel as an example, this panel has 720 vertical lines, each containing three columns of red, green, and blue (RGB) subpixels, resulting in a total of 2160 channels in the vertical direction. Each row of digital image signals is converted to analog signals by an analog-to-digital converter (DAC), then processed by an operational amplifier (OP) for output. In the example shown in Figure 1, two operational amplifiers (OP) form a group. A polarity conversion module (MV-SW) converts the polarity of the output signals of the group's operational amplifiers before outputting them to the corresponding channels.

[0044] As shown in FIG. 2 , in a conventional display panel module, taking a four-channel circuit as an example, the operational amplifier OP1 of the first channel CH1 and the operational amplifier OP2 of the second channel CH2 are a pair of operational amplifiers of opposite polarity. The input voltage of the operational amplifier OP1 is a positive voltage of 6V to 0V, and the input voltage of the operational amplifier OP2 is a negative voltage of 0V to -6V. Similarly, the operational amplifier OP3 of the third channel CH3 and the operational amplifier OP4 of the fourth channel CH4 are a pair of operational amplifiers of opposite polarity. The input voltage of the operational amplifier OP3 is a positive voltage of 6V to 0V, and the input voltage of the operational amplifier OP4 is a negative voltage of 0V to -6V.

[0045] Input voltages of the operational amplifiers in the four paths are respectively V_P1, V_P2, V_N1, and V_N2. The operational amplifiers in the four paths operate independently according to their respective input voltages.

[0046] Considering that in actual operation, the image input signals for each row of the input channel change in real time as the display image changes. Accordingly, the input voltage of the operational amplifier also changes accordingly. Furthermore, at certain times, the input voltages of the operational amplifiers of different channels may be the same. To address this issue, static power consumption can be reduced by multiplexing some channels with the same image input signal for the current row, disconnecting some of these channels, and reducing the current of the power-consuming units on these channels.

[0047] Taking the four-channel circuit shown in FIG2 as an example, as shown in FIG3 , when V_P1 = V_P2, switch EQ1 is closed and switch OE1 is opened, that is, operational amplifier OP3 is turned off, third channel S3 is coupled to the output terminal of operational amplifier OP1, and the current of power-consuming units, such as OP3, on third channel S3 is reduced, thereby saving power. Similarly, when V_N1 = V_N2, switch EQ2 is closed and switch OE2 is opened, that is, operational amplifier OP4 is turned off, fourth channel S4 is coupled to the output terminal of operational amplifier OP2, and the current of power-consuming units, such as OP4, on fourth channel S4 is reduced, thereby saving power.

[0048] Based on the above principles, an embodiment of the present invention provides a method and device for reducing the power consumption of a display panel module. By predetermining the multiplexing channel unit in the display panel module, the image input signal of each row of each channel in the multiplexing channel unit is monitored in real time. When the image input signals of the current rows of different channels are the same, the output ends of some of the channels are disconnected and the current of the power-consuming units on the channels is reduced. The disconnected channels are coupled to the output ends of the non-disconnected channels, and the multiplexed paths provide them with corresponding output signals.

[0049] As shown in FIG. 4 , FIG. 4 is a flow chart of a method for reducing power consumption of a display panel module according to an embodiment of the present invention.

[0050] Before the display panel module operates, step 401 is executed to predetermine a multiplexing channel unit in the display panel module.

[0051] It should be noted that, depending on the structure of the display panel module, each channel may include one or more passages.

[0052] Specifically, the multiplexing channel units can be determined based on the structural design of the display panel module, according to any one or more of the polarity type of each channel, the color mode, and the multiplexing of the channels (i.e., the ratio of multiplexers in the channels). For example, for channels that distinguish between positive and negative polarity, two or more positive polarity channels can be used as multiplexing channel units, and two or more negative polarity channels can be used as multiplexing channel units. For channels that independently perform gamma transformation on the three colors R, G, and B, two or more R channels can be used as multiplexing channel units, two or more G channels can be used as multiplexing channel units, and two or more B channels can be used as multiplexing channel units. For channels that multiplex an operational amplifier (OPA) across the three R, G, and B channels, these three channels can be considered as a single channel to determine the multiplexing channel units.

[0053] It should be noted that the above are merely several different examples of determining a multiplexing channel unit. In specific applications, the multiplexing channel unit needs to be determined based on the type of channel in each display panel module. Display panels are not limited to LCD panels, OLED panels, or LED panels, and LCD panels are not limited to IPS, VA, or TN display panels. An LCD panel includes upper and lower substrates and a light control layer formed between the upper and lower substrates. An OLED panel or LED panel includes upper and lower substrates and a light-emitting layer formed between the upper and lower substrates. The substrates may be made of glass or resin, which is not limited in this embodiment of the present invention.

[0054] During the operation of the display panel module, steps 402 to 404 are executed as follows:

[0055] Step 402: monitor in real time each line of the image input signal of each channel in the multiplexing channel unit.

[0056] Step 403: If the image input signal of the current row of the second channel is the same as the image input signal of the current row of the first channel, disconnect the output end of the second channel, reduce the current of the power unit on the second channel, and couple the second channel to the output end of the first channel.

[0057] Step 404: If the image input signal of the current row of the second channel is different from the image input signal of the current row of the first channel, disconnect the output end of the second channel from the output end of the first channel, restore the current of the power unit in the second channel, and restore the connection of the output end of the second channel.

[0058] It should be noted that the "channel" mentioned in the embodiments of the present invention may include one or more channels, and the above-mentioned "first channel" and "second channel" do not refer to the channel numbered 1 and the channel numbered 2 in order of arrangement, but are only used to refer to different channels in the multiplexing channel unit to distinguish the channels in the multiplexing channel unit that require different processing operations.

[0059] The aforementioned control of connecting and disconnecting the output terminals of each channel, as well as controlling the connection and disconnection of multiplexed channels, can be controlled by corresponding switch signals. It should be noted that the switches EQ1, EQ2, OE1, and OE2 in the example shown in FIG3 are merely schematic illustrations. In specific applications, they are not necessarily physical switches. For example, if the operational amplifier outputs high impedance when turned off, it can also perform a corresponding switching function and can be regarded as a logical switch. In this case, no corresponding physical switch is required; switches EQ1 and EQ2 can be designed as physical switches.

[0060] Furthermore, the disconnection of the second channel output terminal and the control of its coupling with the first channel can be achieved by the same switch signal or by different switch signals, which is not limited in this embodiment of the present invention. For example, the connection or disconnection of the second channel output terminal can be controlled by a first switch signal, while the coupling or disconnection of the second channel output terminal with the first channel can be controlled by a second switch signal.

[0061] The following examples illustrate channel multiplexing in a method for reducing power consumption of a display panel module according to an embodiment of the present invention with reference to Figures 5 to 8, respectively. The display panel is not limited to an LCD panel, an OLED panel, or an LED panel, and the LCD panel is not limited to an IPS, VA, or TN display panel. The LCD panel includes upper and lower substrates and a light control layer formed between the upper and lower substrates. The OLED panel or LED panel includes upper and lower substrates and a light-emitting layer formed between the upper and lower substrates. The substrates may be made of glass or resin, which is not limited in this embodiment of the present invention.

[0062] Referring to Figure 5 , in this example, the multiplexer MUX uses a 1:1 mode, meaning that different channels use independent operational amplifiers. Furthermore, the input image colors corresponding to the channels are arranged in RGB, with adjacent channels having opposite polarities.

[0063] In this example, the multiplexed channel units are: S1 and S7, S2 and S8, S3 and S9, S4 and S10, S5 and S11, S6 and S12. The first channels can be S1, S2, S3, S4, S5, and S6, and the corresponding second channels are S7, S8, S9, S10, S11, and S12. Both the first and second channels include only one path.

[0064] The channel output multiplexing control method is as follows:

[0065] When the current row input image data of channels S1 and S7 are the same (ie, the current row input image data of channels R1 and R3 are the same), the control signal EQ_L1 <1> The output of control channel S7 is disconnected and the control signal EQ_L2 is used <1> The control channel S7 is coupled to the output end of the channel S1; when the current line input image data of the channel S1 and the channel S7 are different (ie, the current line input image data of the path R1 and R3 are different), the control signal EQ_L2 <1> The control channel S7 is disconnected from the output terminal of the channel S1 and the connection of the output terminal of the channel S7 is restored.

[0066] Similarly, the control methods of other groups of multiplexing channel units are similar and will not be described one by one.

[0067] Referring to Figure 6 , in this example, the multiplexer MUX uses a 1:3 mode, meaning that the three channels (R, G, and B) share one operational amplifier. Furthermore, the input image colors corresponding to the channels are arranged in RGB, with adjacent channels having opposite polarities.

[0068] In this example, the multiplexed channel units are: S1 and S3, S2 and S4. Channel S1 contains three paths: R1 / G2 / B1, channel S3 contains three paths: R3 / G4 / B3, channel S2 contains three paths: R2 / G1 / B2, and channel S4 contains three paths: R4 / G3 / B4. The first channels can be S1 and S2, and the corresponding second channels can be S3 and S4. Both the first and second channels have three channels.

[0069] The channel output multiplexing control method is as follows:

[0070] When the current row input image data of channel S1 and channel S3 are the same (ie the current row input image data of path R1, G2, B1 is the same as the current row input image data of path R3, G4, B3), the control signal EQ_L1 <1> The output of control channel S3 is disconnected and the control signal EQ_L2 is used <1> The control channel S3 is coupled to the output end of the channel S1; when the current row input image data of the channel S1 and the channel S7 are different (i.e., the current row input image data of the path R1, G2, B1 is different from the current row input image data of the path R3, G4, B3), the control signal EQ_L2 <1> The control channel S3 is disconnected from the output terminal of the channel S1 and the connection of the output terminal of the channel S3 is restored.

[0071] Referring to Figure 7 , in this example, the multiplexer MUX uses a 1:1 mode, meaning that different channels use independent operational amplifiers. Furthermore, the input image colors corresponding to the channels are arranged in RGB, and adjacent channels have the same polarity.

[0072] In this example, the multiplexed channel units are: S1 and S4, S2 and S5, S3 and S6. The first channel can be S1, S2, and S3, and the corresponding second channel can be S4, S5, and S6. The first channel and the second channel each include only one path.

[0073] The channel output multiplexing control method is as follows:

[0074] When the current row input image data of channels S1 and S4 is the same (ie, the current row input image data of channels R1 and R2 is the same), the control signal EQ_L1 <1> The output of control channel S4 is disconnected and the control signal EQ_L2 is used <1> The control channel S4 is coupled to the output end of the channel S1; when the current line input image data of the channel S1 and the channel S4 are different (ie, the current line input image data of the path R1 and R2 are different), the control signal EQ_L2 <1> The control channel S4 is disconnected from the output terminal of the channel S1 and the connection of the output terminal of the channel S4 is restored.

[0075] Similarly, the control methods of other groups of multiplexing channel units are similar and will not be described one by one.

[0076] Referring to Figure 8, in this example, the multiplexer MUX uses a 1:6 mode, meaning that the six channels (R, G, and B) share a single operational amplifier. Furthermore, the input image colors corresponding to the channels are arranged in RGB format, with adjacent channels sharing the same polarity. Both the first and second channels have six channels.

[0077] The channel output multiplexing control method is as follows:

[0078] When the current row input image data of channels S1 and S2 are the same (i.e. the current row input image data of paths R1, G2, B1, R2, G1, B2 are the same as the current row input image data of paths R3, G4, B3, R4, G3, B4), the control signal EQ_L1 <1> The output of control channel S2 is disconnected and the control signal EQ_L2 is used <1> The control channel S2 is coupled to the output end of the channel S1; when the current row input image data of the channel S1 and the channel S2 are different (i.e., the current row input image data of the path R1, G2, B1, R2, G1, B2 is different from the current row input image data of the path R3, G4, B3, R4, G3, B4), the control signal EQ_L2 is <1> The control channel S2 is disconnected from the output terminal of the channel S1 and the connection of the output terminal of the channel S2 is restored.

[0079] In actual applications, other multiplexing channel unit forms may be used depending on the structural design of the display panel module, which is not limited in the embodiment of the present invention. Regardless of the form, the principle of multiplexing control is similar to the above examples, and will not be described one by one here.

[0080] Furthermore, the multiplexing channel unit may include one or more second channels, that is, two or more channels may be multiplexed, which is not limited in the embodiment of the present invention.

[0081] Accordingly, in a non-limiting embodiment of the method for reducing power consumption of a display panel module according to the present invention, a channel group to be multiplexed in the multiplexing channel unit can be pre-determined, wherein the channel group to be multiplexed includes one or more different channels. A first switching signal is used to control the connection or disconnection of the output terminals of each channel in the channel group to be multiplexed; a second switching signal is used to control the connection or disconnection of the output terminals of each channel in the channel group to be multiplexed with other channels. In other words, multiple channels to be multiplexed in the channel group to be multiplexed can be coupled to the multiplexed channel.

[0082] In addition, the first switching signal and the second switching signal may be generated according to each line of the image input signal of each channel in the channel group to be multiplexed.

[0083] The method for reducing the power consumption of a display panel module provided by an embodiment of the present invention predetermines a multiplexed channel unit in the display panel module, monitors the image input signal of each row of each channel in the multiplexed channel unit in real time, and when the image input signals of the current rows of different channels are the same, disconnects the output ends of some of the channels and reduces the current of the power-consuming units in the second channels, and couples the disconnected channels to the output ends of other channels that are not disconnected. That is, the connections of some power-consuming units of some channels are disconnected and their currents are reduced, and the multiplexed channels provide them with corresponding output signals, thereby effectively saving static power consumption without affecting the charging and discharging effects of the display panel module.

[0084] Reducing the current of the power-consuming unit in the second channel may specifically include shutting down the current of all or part of the paths in the power-consuming unit in the second channel, or reducing the current of all or part of the paths in the power-consuming unit in the second channel. In this way, power consumption can be further reduced.

[0085] It should be noted that the power-consuming unit may be an operational amplifier, a DAC (analog-to-digital converter), or other unit in a path included in a corresponding channel.

[0086] Here, restoring the current of the power-consuming unit refers to restoring the current on each path in the reduced or shut-down power-consuming unit to a normal value, so as to ensure the normal operation of the power-consuming unit.

[0087] Correspondingly, an embodiment of the present invention further provides a device for reducing power consumption of a display panel module, as shown in FIG9 , which is a structural diagram of the device.

[0088] In this embodiment, the apparatus 100 for reducing power consumption of a display panel module includes:

[0089] A setting module 11 is used to predetermine a multiplexing channel unit in the display panel module;

[0090] A monitoring module 12, configured to monitor in real time each line of image input signals of each channel in the multiplexing channel unit;

[0091] The first control module 13 is used to disconnect the output end of the second channel and couple the second channel to the output end of the first channel when the image input signal of the current row of the second channel is the same as the image input signal of the current row of the first channel; and disconnect the output end of the second channel from the output end of the first channel and restore the connection of the output end of the second channel when the image input signal of the current row of the second channel is different from the image input signal of the current row of the first channel.

[0092] The second control module 14 is used to reduce the current of the power-consuming unit in the second channel to reduce power consumption after the first control module 13 disconnects the connection of the output end of the second channel; and restore the current of the power-consuming unit in the second channel to enable the power-consuming unit to operate normally after the first control module 14 disconnects the coupling between the second channel and the output end of the first channel.

[0093] For example, after disconnecting the output end of the second channel, the second control module 14 may shut down the current of all or part of the paths in the power-consuming unit in the second channel, or reduce the current of all or part of the paths in the power-consuming unit in the second channel.

[0094] In practical applications, the second control module 14 may also be integrated with the first control module 13 , which is not limited in this embodiment of the present invention.

[0095] An embodiment of the present invention provides a device for reducing the power consumption of a display panel module. The device predetermines a multiplexed channel unit in the display panel module and monitors the image input signal of each row of each channel in the multiplexed channel unit in real time. When the image input signals of the current rows of different channels are the same, the output ends of some of the channels are disconnected and the current of the power-consuming units in the second channels is reduced, and the disconnected channels are coupled to the output ends of other channels that are not disconnected. In other words, the connections of some power-consuming units of some channels are disconnected and their currents are reduced, and the multiplexed channels provide them with corresponding output signals, thereby effectively saving static power consumption without affecting the charging and discharging effects of the display panel module.

[0096] It should be noted that in various embodiments of the apparatus for reducing power consumption of a display panel module of the present invention, each channel may include one or more paths depending on the structural design of the display panel module. In addition, the second channel may have one or more paths.

[0097] In a non-limiting embodiment, the setting module 11 may also be used to predetermine a channel group to be multiplexed in the multiplexing channel unit, where the channel group to be multiplexed includes one or more different channels.

[0098] Accordingly, the first control module 13 can control the connection or disconnection of the output end of each channel in the channel group to be multiplexed through the first switching signal, and control the coupling or disconnection of the output end of each channel in the channel group to be multiplexed with other channels through the second switching signal.

[0099] Furthermore, the apparatus may further include: a control signal generating module (not shown) configured to generate the first switching signal and the second switching signal according to each line of the image input signal of each channel in the channel group to be multiplexed.

[0100] Accordingly, an embodiment of the present invention further provides a chip including the aforementioned device for reducing power consumption of a display panel module, wherein the display panel is not limited to an LCD panel, an OLED panel, or an LED panel, and the LCD panel is not limited to an IPS, VA, or TN display panel. An LCD panel includes upper and lower substrates and a light control layer formed therebetween. An OLED panel or LED panel includes upper and lower substrates and a light-emitting layer formed therebetween. The substrates may be made of glass or resin, which is not limited in this embodiment of the present invention.
