Description

Technical Field

[0001] The present application relates to the field of liquid crystal display technology, and in particular to a display panel and its energy-saving driving method, device, medium and product. Background Art

[0002] Liquid crystal display products are widely used in televisions, computer monitors, and mobile devices. With the continuous development of LCD display technology, users' energy efficiency requirements for LCD display products are also constantly increasing.

[0003] The power consumption of LCD products is composed of two parts: the driving power consumption of the display itself and the power consumption of the backlight module. Among them, the power consumption of the backlight module is the main source of power consumption for LCD products. Specifically, when the light emitted by the backlight module is projected onto the color filter, only light with the same color as the color filter is allowed to pass through, while light other than the color of the color filter will be absorbed or reflected by the color filter, resulting in significant light loss. In order to ensure sufficient brightness and clear colors on the display, the backlight module has to consume more electricity to generate additional light to compensate for the light filtered out by the color filter, which directly leads to an increase in the power consumption of the backlight module, resulting in a significant increase in the energy consumption of LCD products.

[0004] Therefore, how to reduce the energy consumption of liquid crystal display products is a technical problem that needs to be solved urgently. Summary of the Invention

[0050] Liquid crystal display products are widely used in televisions, computer monitors, and mobile devices. With the continuous development of LCD display technology, users' energy efficiency requirements for LCD display products are also constantly increasing.

[0051] The power consumption of LCD products is composed of two parts: the driving power consumption of the display itself and the power consumption of the backlight module. Among them, the power consumption of the backlight module is the main source of power consumption for LCD products. Specifically, when the light emitted by the backlight module is projected onto the color filter, only light with the same color as the color filter is allowed to pass through, while light other than the color of the color filter will be absorbed or reflected by the color filter, resulting in significant light loss. In order to ensure sufficient brightness and clear colors on the display, the backlight module has to consume more electricity to generate additional light to compensate for the light filtered out by the color filter, which directly leads to an increase in the power consumption of the backlight module, resulting in a significant increase in the energy consumption of LCD products.

[0052] In order to solve the technical defect of high energy consumption of existing liquid crystal display products, the present application provides a display panel and its energy-saving driving method, device, medium and product.

[0053] The present application provides a display panel, referring to Figure 1 As shown, Figure 1 This is a structural block diagram of the first embodiment of the display panel of the present application. The display panel includes: a plurality of pixel units 100 arranged in an array, each pixel unit 100 including a plurality of monochrome sub-pixels of different colors, each pixel unit 100 in the same row being electrically connected to a row scan line Gn of the corresponding row, each monochrome sub-pixel of the same color being arranged along a column direction to form a monochrome sub-pixel column, each monochrome sub-pixel column being electrically connected to a column scan line Sn of the corresponding column; a target sub-pixel column, each monochrome sub-pixel in the target sub-pixel column being electrically connected to a black insertion signal line Kn of the row in which it is located, the target sub-pixel column being a monochrome sub-pixel column of any one color among a plurality of monochrome sub-pixel columns of different colors; and a color filter assembly 200 including a transparent glass substrate covering the target sub-pixel column and a plurality of color filters, each color filter having a different color from the target sub-pixel column, each color filter covering a monochrome sub-pixel column of the same color.

[0054] In this embodiment, the monochrome sub-pixels in the target sub-pixel column can be understood as Figure 1As shown in the target sub-pixel 11, for example, the plurality of monochrome sub-pixels of different colors can be three monochrome sub-pixels of different colors, and the three monochrome sub-pixels of different colors are respectively Figure 1 The shaded square rectangles, shaded diagonal rectangles, and shaded diamond rectangles in the pixels shown are represented, and Figure 1 The hatched rectangle is a target sub-pixel, and the multiple target sub-pixels are all monochrome sub-pixels of the same color, and the target sub-pixel 11 can be the monochrome sub-pixel with the highest luminous efficiency among the multiple monochrome sub-pixels of different colors. In other words, the present application replaces the color filter of the same color as the target sub-pixel in the original color filter assembly with a colorless transparent glass substrate, also called a transparent glass substrate, which can be used Figure 1 The dotted shaded area shown is represented; alternatively, the color filter of the same color as the target sub-pixel in the original color filter assembly is replaced with a hollow frame; next, during one display frame time of the display panel, the row scan line Gn of each row is connected to the gate drive signal row by row to start charging multiple monochrome sub-pixels of different colors, but since the column scan line Sn corresponding to the target sub-pixel 11 provides a power signal to the target sub-pixel 11, and the column scan line Sn corresponding to the monochrome sub-pixels other than the target sub-pixel 11 does not provide a power signal, the target sub-pixels 11 of all rows are connected to the power signal under the drive of the gate drive signal and light up row by row, and the target sub-pixels of each row on the display panel are connected to the gate drive signal. The target sub-pixels 11 are activated in sequence according to the row scan order and display the target frame time within the display frame time. The target sub-pixels 11 in each row are then connected to the black insertion signal output by the black insertion signal line Kn of the corresponding row for black insertion, thereby ensuring that the target sub-pixels 11 in each row only display the target frame time while optimizing the display efficiency of the target sub-pixels 11. After the target sub-pixels 11 in the last row of all rows have completed black insertion, the monochrome sub-pixels (i.e., the sub-pixels of other colors) other than the target sub-pixel 11 are connected to the power signal provided by the corresponding column scan line Sn. All other color sub-pixels are driven by the gate drive signal and connected to the power signal to display the same light-on time as the target frame time. In other words, the present application alternates the light emission of the target sub-pixel 11 and the sub-pixels of other colors, so that after the target sub-pixels 11 in each row display the target frame time, the sub-pixels of other colors are enabled to display the same light-on time as the target frame time under the power signal provided by the corresponding column scan line Sn. This not only improves the color contrast and clarity of the displayed image, but also significantly reduces the overall energy consumption of the liquid crystal display product.

[0055] It should be noted that the plurality of pixel units 100 may include at least a red sub-pixel, a green sub-pixel and a blue sub-pixel; illustratively, Figure 1 Taking the pixel unit 100 shown as an example, Figure 1The shaded squares in the pixel unit 100 can be understood as representing red monochromatic sub-pixels (i.e., red sub-pixels). Figure 1 The hatched rectangle in the pixel unit 100 can be understood as representing a green monochromatic sub-pixel (ie, a green sub-pixel). Figure 1 The shaded diamond-shaped rectangles in the pixel unit 100 can be understood as representing a blue monochromatic sub-pixel (ie, a blue sub-pixel).

[0056] In a specific embodiment, referring to Figure 2 As shown, the backlight module is arranged above the display panel. Figure 2 The circle in the backlight module shown represents the LED light. Figure 2 The square convex shape (i.e., red filter), the oblique convex shape (i.e., green filter), and the diamond convex shape (i.e., blue filter) shown can represent the color filter component 200. A black matrix is ​​arranged between the color filter component 200 and the color filter component substrate. A strip frame glue is arranged under the color filter component 200. The shaded strip shape arranged between the strip frame glue and the liquid crystal layer is an orientation film. A thin film transistor and a storage capacitor are arranged between the liquid crystal layer and the thin film transistor substrate. The thin film transistor can be represented by a rectangular box in the convex shape arranged between the liquid crystal layer and the thin film transistor substrate, and the storage capacitor can be represented by a black square in the convex shape arranged between the liquid crystal layer and the thin film transistor substrate. For example, the white light emitted from the backlight module loses about 52% of its light when passing through the lower polarizer. The remaining 48% of the white light passes through opaque materials such as metal wiring and black matrices, and another 3.5% is lost. After the remaining 48% of the white light reaches the color filter, only about 10% of the light passes through the color filter because only the light of the color corresponding to the color filter can pass through the color filter. Of the remaining 10%, only 7% of the light is projected to the human eye through the upper polarizer. Since green light accounts for the largest proportion when the backlight emits white light, followed by red light, and white light accounts for the least, the target sub-pixel 11 set in this application is a monochrome sub-pixel representing green (i.e., a G pixel). Specifically, Figure 3 The green filter (i.e., green filter) in the normal color filter shown in (a) is directly removed and only the frame structure of the original green filter is retained, or replaced with a colorless transparent glass plate (i.e., transparent glass substrate), forming the color filter set in this application. Figure 3 The color filter assembly 200 shown in (b) of FIG. 1 significantly reduces the light loss of the green light emitted by the backlight module on the G pixel, thereby effectively reducing the overall energy consumption of the liquid crystal display product.

[0057] In addition, it should be noted that the above-mentioned embodiment partially sets the target sub-pixel 11 as a monochrome sub-pixel representing green, which is only a feasible embodiment of the present application. The target sub-pixel 11 can also be set as a monochrome sub-pixel representing red or blue, and the present application does not impose any restrictions on this.

[0058] Figure 3 The "R" shown here represents the red filter in the color filter assembly 200. Figure 3 The "G" shown here represents the green filter in the color filter assembly 200. Figure 3 The “B” shown represents the blue filter in the color filter assembly 200 .

[0059] In summary, the present application provides a display panel with target sub-pixels 11 in each row electrically connected to the black insertion signal line Kn of the corresponding row. Since the target sub-pixel 11 is the single-color sub-pixel with the highest luminous efficiency among the three single-color sub-pixels of different colors, and the transparent glass substrate of the color filter assembly 200 is only provided above each target sub-pixel 11 in the same column instead of the color filter, while the other color sub-pixels retain the color filter of the corresponding color. As a result, the light emitted by the backlight module applied to the display panel acting on the target sub-pixel 11 can be directly displayed without color filtering by the color filter assembly 200. That is, by arranging a transparent glass substrate above the target sub-pixel 11, the phenomenon of the light emitted by the backlight module acting on the target sub-pixel 11 being filtered out by the color filter component 200 is avoided, thereby effectively improving the light utilization rate of the light emitted by the backlight module acting on the target sub-pixel 11, and significantly reducing the light loss of the light emitted by the backlight module acting on the target sub-pixel 11 when passing through the color filter component 200, thereby making it unnecessary for the backlight module to generate additional light to compensate for the filtered light, and effectively reducing the energy consumption of the liquid crystal display product by significantly reducing the power consumption of the backlight module.

[0060] Further, in some feasible embodiments, referring to Figure 4 , Figure 4This is a schematic diagram of the circuit principles involved in an embodiment of a display panel of the present application. A single-color sub-pixel of the same color as the target sub-pixel column constitutes a target sub-pixel 11. The target sub-pixel 11 includes at least a first thin-film transistor T1, a second thin-film transistor T2, a first capacitor C1, and a second capacitor C2. The gate terminal of the first thin-film transistor T1 is electrically connected to the row scan line Gn of the corresponding row, the first path terminal of the first thin-film transistor T1 is electrically connected to the column scan line Sn of the corresponding column, and the second path terminal of the first thin-film transistor T1 is electrically connected to the first end of the first capacitor C1, the first end of the second capacitor C2, and the first path terminal of the second thin-film transistor T2, respectively. The gate terminal of the second thin-film transistor T2 is electrically connected to the black insertion signal line Kn of the corresponding row, the second path terminal of the second thin-film transistor T2 and the second end of the second capacitor C2 are electrically connected to the second voltage terminal AVcom, and the second end of the first capacitor C1 is electrically connected to the first voltage terminal Vcom.

[0061] In this embodiment, referring to Figure 4 The display panel provided in the present application may further include a first voltage terminal Vcom and a second voltage terminal AVcom. Figure 4As shown, the gate terminals of the first thin-film transistors T1 in each row of target sub-pixels 11 are connected to the gate drive signal output by the corresponding row scan line Gn, and charging is started row by row, so that the first thin-film transistors T1 in each row are switched from the off state to the on state. At this time, the first path terminals of the first thin-film transistors T1 in the same column are connected to the power signal provided by the corresponding column scan line Sn. The first thin-film transistors T1 in each row are driven by the gate drive signal to connect to the power signal in accordance with the row scan sequence to charge the second capacitors C2 in each row, so that the charged second capacitors C2 in each row discharge to the corresponding LED lights in the backlight module in accordance with the row scan sequence and emit the same light as the target sub-pixel 11. Since a transparent glass substrate is provided above the target sub-pixel 11, the light of the target sub-pixel 11 can directly pass through the transparent glass substrate, significantly reducing the light loss of the light of the target sub-pixel 11 during the light transmission process. Next, the charged second capacitors C2 in each row discharge to the corresponding LED lights in the backlight module in accordance with the row scan sequence and emit the same light as the target sub-pixel 11. When the target frame time in a display frame time of the display panel is displayed, the gate terminal of the second thin-film transistor T2 in each row of target sub-pixels 11 is sequentially connected to the black insertion signal output by the corresponding black insertion signal line Kn according to the row scanning order, and the power signal connected to the first end of the first thin-film transistor T1 electrically connected to the second capacitor C2 is pulled down to the second voltage terminal AVcom row by row, so that the second capacitor C2 of each row no longer provides power to the corresponding LED lamp in the backlight module in sequence according to the row scanning order. This not only avoids the occurrence of ghosting in the light that is the same as the target sub-pixel 11 that is lit up row by row, but also significantly improves the display quality of the light that is the same as the target sub-pixel 11 that is lit up row by row, but also makes the corresponding LED lamp in the backlight module that emits the same light as the target sub-pixel 11 go out, ensuring that the target sub-pixel 11 in each row only displays the target frame time according to the row scanning order.

[0062] It should be noted that the target sub-pixel 11 set in this application is a monochrome sub-pixel representing green (ie, a G pixel). Figure 4 The three column scan lines Sn shown are arranged from left to right as the first column scan line, the second column scan line and the third column scan line, wherein the first column scan line can be understood as Figure 4 The R pixel (i.e., the monochrome sub-pixel representing red) shown in the “R” provides a power signal; the second column scan line can be understood as Figure 4 The G pixel shown by "G" provides power signal; the third column scan line can be understood as Figure 4 The B pixel indicated by “B” (ie, a monochrome sub-pixel representing blue) provides a power signal.

[0063] Furthermore, in some other feasible embodiments, referring to Figure 4The display panel includes other color sub-pixels, each of which is a monochrome sub-pixel other than the target sub-pixel. The other color sub-pixels include at least a third thin-film transistor T3, a third capacitor C3, and a fourth capacitor C4. The gate terminals of the third thin-film transistors T3 are electrically connected to the row scan line Gn connected to the first thin-film transistor T1 in the same row, the first path terminal of the third thin-film transistor T3 is electrically connected to the column scan line Sn of the corresponding column, and the second path terminal of the third thin-film transistor T3 is electrically connected to the first terminal of the third capacitor C3 and the first terminal of the fourth capacitor C4, respectively. The second terminal of the third capacitor C3 is electrically connected to the first voltage terminal Vcom, and the second terminal of the fourth capacitor C4 is electrically connected to the second voltage terminal AVcom.

[0064] In this embodiment, referring to Figure 4 After the target sub-pixels 11 in each row are sequentially black-inserted in accordance with the row scan sequence to ensure that the target sub-pixels 11 in each row display the target frame time, the third thin-film transistors T3 in all other color sub-pixels are synchronously connected to the gate drive signal provided by the corresponding row scan line Gn, which is provided in accordance with the row scan sequence. Therefore, at this time, the third thin-film transistors T3 in all other color sub-pixels are switched from an off state to an on state. When the column scan lines Sn corresponding to all other color sub-pixels provide power signals of corresponding colors, the fourth capacitors C4 in all other color sub-pixels are charged by the power signals of corresponding colors. The charged fourth capacitors C4 in each row are discharged to the corresponding LEDs in the backlight module, emitting the same light as the other color sub-pixels and displaying the same light-on time as the target frame time. This achieves a mixed display effect of three monochrome sub-pixels of different colors with the same display time, utilizing the residual inertia of the human eye, thereby ensuring color uniformity of the display panel image.

[0065] In a specific embodiment, referring to Figures 4 and 5 In this application, the target sub-pixel 11 is set as a G pixel, the other color sub-pixels are set as R pixels and B pixels, and the display frame time is from T1 to T5. The energy-saving driving principle of the display panel is as follows:

[0066] At time T1, each row scan line Gn starts to scan and charge row by row. Since the liquid crystal light valve electrically connected to the second column scan line is open, the second column scan line provides a power signal to the G pixel, but the liquid crystal light valve electrically connected to the first column scan line and the liquid crystal light valve electrically connected to the third column scan line are closed, so that the first column scan line and the third column scan line do not provide a power signal to the R pixel and the B pixel. The corresponding LED light in the backlight module acts on the G pixel to emit green light (that is, the backlight G is on), and the corresponding LED light in the backlight module acts on the R pixel and the B pixel not to emit light (that is, the backlight RB is black), but since the liquid crystal light valves of the R pixel and the B pixel are open, the R pixel and the B pixel start to charge at time T1; since the time from T1 to T2 is 0.2 5 frames (i.e., target frame time), after the G pixels in the corresponding rows display the target frame time, the black insertion scan lines of each column are sequentially connected to the black insertion signal in accordance with the row scanning order for black insertion, that is, at time T2, the backlight G of the first row of all rows begins to turn off, until at time T3, after each row scan line Gn completes charging of all rows, the backlight G of the last row of all rows from time T3 to time T4 lights up, and after at time T4, the backlight G of the last row of all rows is turned off, because the backlight G of all rows is charged with the voltage AVcom when the second thin-film transistor T2 is turned on, the liquid crystal light valve electrically connected to the second column scan line is closed. At this time, the backlight G of all rows completes display and the backlight G display time of all rows is 0.25 frame, thereby ensuring the uniformity of full-screen display of the display panel. Until the backlight G of the last row among all the rows is connected to the voltage AVcom and blacked out, so that the liquid crystal light valve corresponding to the backlight G of the last row is closed, power signals are provided to the R pixels and B pixels through the first column scan line and the third column scan line respectively, so that the R pixels and B pixels are fully charged and the 0.25 frame from T4 to T5 is displayed to complete the display of the backlight RB.

[0067] In another embodiment, the energy-saving driving principle of the display panel can also be used for Figure 6 In the circuit shown, two row scan lines Gn are provided for each row of pixels, one row scan line Gn of the two row scan lines Gn is electrically connected to any two monochrome sub-pixels of three different colors, and the other row scan line Gn of the two row scan lines Gn is electrically connected to the monochrome sub-pixels not connected to one row scan line Gn of the two row scan lines Gn. Figure 6 , Figure 6 The two column scan lines Sn shown are arranged from left to right as the first column scan line and the second column scan line. In addition, the first pixel row is provided with two row scan lines Gn, which can be represented by gate scan line G1 and gate scan line G1'; the second pixel row is provided with two row scan lines Gn, which can be represented by gate scan line G2 and gate scan line G2'; the third pixel row is provided with two row scan lines Gn, which can be represented by gate scan line G3 and gate scan line G3'. Figure 6 The red pixels and the green pixels in the first pixel row are electrically connected to the gate scan line G1. Figure 6 The red pixels and the green pixels in the second pixel row are electrically connected to the gate scan line G2. Figure 6 The red pixels and green pixels in the third pixel row are electrically connected to the gate scan line G3. Figure 6 The blue pixels in the first to third pixel rows are electrically connected to the gate scan line G1 ′, the gate scan line G2 ′, and the gate scan line G3 ′, respectively; Figure 6 The red pixel and the blue pixel shown are both provided with power signals via the first column scan line.

[0068] In summary, since green light accounts for the largest proportion when the backlight module emits white light, followed by red light, and blue light accounts for the least, RGB is originally displayed simultaneously, and the green light of the white light will be wasted at the R / B pixel position. This application utilizes the residual inertia of the human eye and sets a transparent glass substrate above the G pixel position. When the backlight G is emitting light, the backlight G directly displays the target frame time through the transparent glass substrate and the backlight R / B does not emit light. When the backlight R / B is emitting light, the backlight G does not emit light, thereby significantly reducing the energy consumption of the display panel.

[0069] Further, in some feasible embodiments, referring to Figure 7 The display panel includes a plurality of partition control areas arranged row by row, and the partition control area is composed of N rows of target sub-pixels arranged row by row, where N is a natural number greater than 1.

[0070] In this embodiment, the display panel includes a plurality of partition control areas arranged row by row, and each partition control area includes at least N rows of target sub-pixels 11. In other words, the present application can also divide the target color area where the target sub-pixel 11 is located into Figure 7 The plurality of partition control areas are arranged row by row, that is, in a feasible embodiment, the target color area where the target sub-pixel 11 is located is divided into Figure 7 The 10 partition control areas shown in the figure each include at least N rows of target sub-pixels 11. When the liquid crystal light valve of the backlight G in the corresponding partition control area is turned on, the backlight G in the corresponding partition control area lights up; when the liquid crystal light valve of the backlight G in the corresponding partition control area is closed, the backlight G in the corresponding partition control area goes out, thereby achieving energy-saving effect of the display panel.

[0071] Furthermore, in other feasible embodiments, the display panel includes: a target liquid crystal light valve corresponding to each of the partitioned control areas, each of the target liquid crystal light valves being electrically connected to the column scan lines Sn corresponding to each of the target sub-pixels in the first row to the Nth row in the corresponding partitioned control area; a plurality of monochrome liquid crystal light valves, the color of each of the monochrome liquid crystal light valves being different from the color of the target sub-pixel column, each of the monochrome liquid crystal light valves being electrically connected to the column scan lines Sn connected to the monochrome sub-pixel column of the same color.

[0072] In this embodiment, since the backlight RB is displayed together after the row scan line Gn scans the display panel, the backlight RB does not need to be partitioned, and the backlight G is turned on and off row by row, so that each monochrome liquid crystal light valve can be electrically connected to the column scan line Sn connected to each monochrome sub-pixel of the same column of the corresponding color; each target liquid crystal light valve is electrically connected to the column scan line Sn corresponding to each target sub-pixel 11 in the first row to the Nth row in the corresponding partition control area, thereby achieving Figure 7 The partition control effect shown can achieve further energy saving of the display panel.

[0073] It should be noted that when the target sub-pixel 11 is a G pixel, the target liquid crystal light valve is the liquid crystal light valve corresponding to the G pixel, and the monochrome liquid crystal light valve is the liquid crystal light valve corresponding to the R pixel or the liquid crystal light valve corresponding to the B pixel.

[0074] Furthermore, based on the first embodiment of the display panel of the present application, a second embodiment of the energy-saving driving method of the present application is proposed.

[0075] The energy-saving driving method of the present application is applied to any of the above-mentioned display panels. The energy-saving driving method of the present application is executed by a terminal device that saves energy on the display panel. The energy-saving driving method of the present application includes the following implementation steps S10 to S20.

[0076] Step S10: When each row of scan lines is connected to the gate drive signal row by row to start charging multiple monochrome sub-pixels of different colors in each pixel unit of the corresponding row, the target sub-pixels of the corresponding row are connected to the power signal transmitted by the column scan line of the corresponding column under the drive of the gate drive signal and light up row by row.

[0077] In this embodiment, during the row-by-row scanning process of the display panel, each row scan line receives a gate drive signal in sequence according to the row scan order to charge multiple monochrome sub-pixels of different colors in each pixel unit. Next, the liquid crystal light valve connected to the column scan line corresponding to the target sub-pixel opens (i.e., the liquid crystal light valve is in the on state), thereby providing a power signal to the target sub-pixel. The liquid crystal light valve connected to the column scan line corresponding to the monochrome sub-pixel other than the target sub-pixel is closed (i.e., the liquid crystal light valve is in the off state), and thus no power signal is provided. In other words, the target sub-pixels in each row receive the power signal connected to the column scan line of the corresponding column under the drive of the gate drive signal, so that the target sub-pixels in each row are illuminated row by row according to the row scan order.

[0078] Step S20: After the target sub-pixels in each row display the target frame time row by row, the target sub-pixels in each row are connected to the black insertion signal output by the black insertion signal line of the row to perform black insertion row by row, until all the target sub-pixels complete black insertion, and then the other color sub-pixels in each row are enabled to simultaneously connect to the power signal transmitted by the column scan line of the corresponding column under the drive of the gate drive signal, and all the other color sub-pixels display the same light-on time as the target frame time; wherein the target frame time is the light-on time of the target sub-pixel within one frame display time of the display panel, and the other color sub-pixels are monochrome sub-pixels other than the target sub-pixel.

[0079] In this embodiment, after the target subpixels in each row are illuminated row by row in a row scan sequence and display the target frame time row by row, the target subpixels in each row are then connected to the black insertion signal output by the black insertion signal line of the corresponding row in the row scan sequence to perform black insertion. This ensures that the target subpixels in each row display only the target frame time while optimizing the display efficiency of the target subpixels. After the target subpixels in the last row of all rows have completed black insertion, the monochrome subpixels (i.e., the subpixels of the other colors) other than the target subpixels are connected to the power signal provided by the corresponding column scan line. All other color subpixels are then connected to the power signal under the gate drive signal to display the same lighting time as the target frame time. In other words, the present application alternates the lighting of the target subpixels and the subpixels of the other colors, so that after the target subpixels in each row display the target frame time, the subpixels of the other colors are enabled to display the same lighting time as the target frame time under the power signal provided by the corresponding column scan line. This not only improves the color contrast and clarity of the displayed image, but also significantly reduces the overall energy consumption of the liquid crystal display product.

[0080] Furthermore, in other feasible embodiments, when each of the row scan lines is connected to the gate drive signal row by row to start charging three monochrome sub-pixels of different colors, the energy-saving driving method of the present application may also include the following implementation steps A10 to A30.

[0081] Step A10: Each target liquid crystal light valve outputs the power supply signal to the column scan lines corresponding to the target color pixels in the first row to the Nth row in the corresponding partition control area, so that the target color pixels in N rows in the partition control area are driven by the gate drive signal to receive the power supply signal row by row to emit light.

[0082] In this embodiment, each target liquid crystal light valve outputs a power supply signal to the column scan lines corresponding to the target sub-pixels in the first row to the Nth row in the corresponding partition control area, so that the target sub-pixels in the N rows in the partition control area are connected to the power supply signal row by row in accordance with the row scanning order under the drive of the gate drive signal to emit light, thereby achieving the goal of only the target sub-pixels in all rows in the partition control area to emit light.

[0083] Step A20: After the target color pixels in each row of each partition control area display the target frame time row by row, the target color pixels in each row of each partition control area are connected to the black insertion signal output by the black insertion signal line of the row for black insertion.

[0084] In this embodiment, after the target sub-pixels of all rows in each partitioned control area display the target frame time in sequence according to the row scanning order, the target sub-pixels of all rows in each partitioned control area are connected to the black insertion signal output by the black insertion signal line of the corresponding row row by row according to the row scanning order for black insertion, thereby achieving the effect of black insertion for only the target sub-pixels of all rows in the partitioned control area, avoiding the ghosting phenomenon caused by the target sub-pixels of all rows lighting up row by row, and significantly improving the display quality of the target sub-pixels of all rows in the partitioned control area.

[0085] Step A30: After all the target color pixels in each of the partitioned control areas have completed black insertion, in response to the target color display request of the next partitioned control area of ​​each of the partitioned control areas, enable the target liquid crystal light valve corresponding to each of the partitioned control areas to switch from the on state to the off state.

[0086] In this embodiment, after all the row target sub-pixels of each partition control area have completed the black insertion processing, in response to the target color display request of the next partition control area of ​​each partition control area, the target liquid crystal light valve corresponding to each partition control area is enabled to switch from the on state to the off state, ensuring that the display panel can accurately control the opening and closing time of each partition control area during the display process, thereby avoiding unnecessary energy waste and achieving further energy saving of the display panel.
