DETAILED DESCRIPTION

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.

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

Take the commonly used 720X1280 resolution LCD panel in the market as an example. The panel has 720 vertical lines, and each line contains three columns of red, green and blue (RGB) sub-pixels. Therefore, there are 2160 channels in the vertical direction. Each row of digital image signal input is converted into an analog signal by the analog-to-digital converter DAC, and then processed by the operational amplifier OP for output. In the example shown in Figure 1, every two operational amplifiers OP are grouped together, and the polarity conversion module MV-SW converts the polarity of the output signal of the operational amplifier of the group and outputs it to the corresponding path.

As shown in FIG. 2 , in an existing display panel module, a four-channel circuit is taken as an example, wherein 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 ...0V to -6V. The voltage is 6V to 0V, and the input voltage of the operational amplifier OP4 is a negative voltage of 0V to -6V.

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

Considering that in actual operation, the image input signals of each row inputted by different channels also change in real time according to the difference and change of the displayed screen. Accordingly, the input voltage of the operational amplifier also changes accordingly, and at some time, the input voltages of the operational amplifiers of different channels may be the same. In view of this feature, by controlling some channels with the same image input signals of the current row through multiplexing, disconnecting some of the channels and reducing the current of the power unit on the channels, static power consumption can be saved.

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

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. The method predetermines a multiplexing channel unit in the display panel module, monitors the image input signal of each row of each channel in the multiplexing channel unit in real time, and 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, and the disconnected channels are coupled to the output ends of the non-disconnected channels, so that the multiplexed paths provide corresponding output signals for them.

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.

Before the display panel module works, step 401 is executed to predetermine a multiplexing channel unit in the display panel module.

It should be noted that, depending on the different structures of the display panel module, each channel may include one or more passages.

Specifically, the multiplexing channel unit can be determined according to the structural design of the display panel module, according to any one or more of the polarity type, color mode, and multiplexing condition of each channel (i.e., the ratio of multiplexers in the channel). For example, for channels that distinguish between positive and negative polarities, 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 perform GAMMA conversion on 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 the case where the three channels, R, G, and B, multiplex one operational amplifier, the three channels can be considered as one channel to determine each multiplexing channel unit.

It should be noted that the above are only several different examples of determining the multiplexing channel unit. In specific applications, it is necessary to determine it according to the type of the channel in each display panel module, wherein the display panel is not limited to LCD panel, OLED panel, LED panel, and the LCD panel is not limited to IPS, VA, TN display panel. The LCD panel includes an upper and lower substrate and a light control layer formed between the upper and lower substrates, and the OLED panel or LED panel includes an upper and lower substrate and a light-emitting layer formed between the upper and lower substrates. The material of the substrate can be glass or resin, which is not limited in the embodiment of the present invention.

During the operation of the display panel module, steps 402 to 404 are performed as follows:

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

Step 403, if the image input signal of the current line of the second channel is the same as the image input signal of the current line 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.

Step 404, if the image input signal of the current line of the second channel is different from the image input signal of the current line of the first channel, disconnect the coupling between the output end of the second channel and 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.

It should be noted that the "channel" mentioned in the embodiment 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 multiplexed channel unit to distinguish the channels in the multiplexed channel unit that need to perform different processing operations.

The above-mentioned control of connecting and disconnecting the output ends of each channel, and controlling the connection and disconnection of different channels for multiplexing, 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 only a schematic description. In specific applications, they are not necessarily physical switch tubes. For example, if the operational amplifier outputs high impedance when turned off, it can also play a corresponding switching function and can be regarded as a logical switch. In this case, the corresponding physical switch tube is not required; and the switches EQ1 and EQ2 can be designed as physical switch tubes.

In addition, the disconnection of the output end of the second channel and the control of coupling with the first channel can be achieved through the same switch signal or different switch signals, which is not limited in the embodiment of the present invention. For example, the connection or disconnection of the output end of the second channel can be controlled by the first switch signal; the coupling or disconnection of the output end of the second channel with the first channel can be controlled by the second switch signal.

The channel multiplexing in the method for reducing the power consumption of the display panel module according to the embodiment of the present invention is illustrated below with reference to FIGS. 5 to 8 respectively, 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. The LCD panel includes an upper and lower substrate and a light control layer formed between the upper and lower substrates, and the OLED panel or LED panel includes an upper and lower substrate and a light emitting layer formed between the upper and lower substrates, and the material of the substrate can be glass or resin, which is not limited in the embodiment of the present invention.

Referring to FIG. 5 , in this example, the multiplexer MUX adopts a 1:1 mode, that is, different The channels use independent operational amplifiers. Moreover, the input image colors corresponding to the channels are arranged in RGB, and the polarities of adjacent channels are opposite.

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 channel can be S1, S2, S3, S4, S5, S6, and the corresponding second channel is S7, S8, S9, S10, S11, S12. Both the first channel and the second channel include only one path.

The channel output multiplexing control method is as follows:

When the current row input image data of channel S1 and channel S7 are the same (i.e., the current row input image data of paths R1 and R3 are the same), the control signal EQ_L1<1> controls the output end of channel S7 to be disconnected, and controls channel S7 to be coupled to the output end of channel S1 through the control signal EQ_L2<1>; when the current row input image data of channel S1 and channel S7 are different (i.e., the current row input image data of paths R1 and R3 are different), the control signal EQ_L2<1> controls channel S7 to be disconnected from the output end of channel S1, and restores the connection of the output end of channel S7.

By analogy, the control methods of other groups of multiplexing channel units are similar and will not be described one by one.

6 , in this example, the multiplexer MUX adopts a 1:3 mode, that is, one operational amplifier is multiplexed for three channels of R, G, and B. Moreover, the input image colors corresponding to the channels are arranged in RGB, and the polarities of adjacent channels are opposite.

In this example, the multiplexed channel units are: S1 and S3, S2 and S4. Channel S1 includes 3 paths R1/G2/B1, channel S3 includes 3 paths R3/G4/B3, channel S2 includes 3 paths R2/G1/B2, and channel S4 includes 3 paths R4/G3/B4. The first channel can be S1, S2, and the corresponding second channel is: S3, S4. Both the first channel and the second channel include three channels.

The channel output multiplexing control method is as follows:

The current row input image data of channels S1 and S3 are the same (that is, the current row input image data of channels R1, G2, B1 and the current row input image data of channels R3, G4, B3 are the same). The control signal EQ_L1<1> controls the output end of channel S3 to be disconnected, and controls the output end of channel S3 to be coupled to the output end of channel S1 through the control signal EQ_L2<1>; when the current row input image data of channel S1 and channel S7 are different (that is, any of the current row input image data of paths R1, G2, B1 is different from the current row input image data of paths R3, G4, B3), the control signal EQ_L2<1> controls channel S3 to be disconnected from the output end of channel S1, and restores the connection of the output end of channel S3.

Referring to FIG7 , in this example, the multiplexer MUX adopts a 1:1 mode, that is, different channels use independent operational amplifiers. Moreover, the input image colors corresponding to the channels are arranged in RGB, and adjacent channels have the same polarity.

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

The channel output multiplexing control method is as follows:

When the current row input image data of channel S1 and channel S4 are the same (i.e., the current row input image data of paths R1 and R2 are the same), the control signal EQ_L1<1> controls the output end of channel S4 to be disconnected, and controls channel S4 to be coupled to the output end of channel S1 through the control signal EQ_L2<1>; when the current row input image data of channel S1 and channel S4 are different (i.e., the current row input image data of paths R1 and R2 are different), the control signal EQ_L2<1> controls channel S4 to be disconnected from the output end of channel S1, and restores the connection of the output end of channel S4.

By analogy, the control methods of other groups of multiplexing channel units are similar and will not be described one by one.

Referring to FIG8 , in this example, the multiplexer MUX adopts a 1:6 mode, that is, six channels of R, G, and B multiplex one operational amplifier. Moreover, the input image colors corresponding to the channels are arranged in RGB, and the polarities of adjacent channels are the same. The first channel and the second channel each include 6 channels.

The channel output multiplexing control method is as follows:

When the current row input image data of channel S1 and channel S2 are the same (that is, 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> controls the output end of channel S2 to be disconnected, and controls channel S2 to be coupled to the output end of channel S1 through the control signal EQ_L2<1>; when the current row input image data of channel S1 and channel S2 are different (that is, any of the current row input image data of paths R1, G2, B1, R2, G1, B2 is different from the current row input image data of paths R3, G4, B3, R4, G3, B4), the control signal EQ_L2<1> controls channel S2 to be disconnected from the output end of channel S1, and restores the connection of the output end of channel S2.

In practical applications, according to different display panel module structure designs, there may be other multiplexing channel unit forms, which are not limited in the embodiments 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.

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

Accordingly, in a non-limiting embodiment of the method for reducing the power consumption of the display panel module of the present invention, a channel group to be multiplexed in the multiplexing channel unit can also be predetermined, and the channel group to be multiplexed includes one or more different channels. The connection or disconnection of the output end of each channel in the channel group to be multiplexed is controlled by a first switch signal; the coupling or disconnection of the output end of each channel in the channel group to be multiplexed with other channels is controlled by a second switch signal, that is, the linkage of the coupling of multiple channels to be multiplexed in the channel group to be multiplexed with the multiplexed channel can be realized.

In addition, the first switch signal and the second switch signal may also be generated according to each line of the image input signal of each channel in the channel group to be multiplexed.

Wherein, reducing the current of the electric unit in the second channel may specifically be closing the current of all or part of the paths in the electric unit in the second channel; or reducing the current of all or part of the paths in the electric unit in the second channel. In this way, power consumption can be further reduced.

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.

Herein, 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.

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 schematic diagram of the device.

The second control module 14 is used to reduce the current of the power unit in the second channel after the first control module 13 disconnects the output end of the second channel, so as to reduce after the first control module 14 disconnects the coupling between the second channel and the output end of the first channel, the current of the power unit in the second channel is restored so that the power unit works normally.

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.

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.

In other words, 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 and not affecting the charging and discharging effect of the display panel module.

It should be noted that in each embodiment of the device for reducing power consumption of a display panel module of the present invention, each channel may include one or more paths according to different structural designs of the display panel module.
