[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] The contrast ratio of current LCDs used for typical 3D displays depends largely on the LCD technology used. For example, IPS LCDs can achieve a contrast ratio of 1000 to 1500, while VA LCDs can achieve a contrast ratio of 3000 to 5000. This can hinder the display quality when displaying high-quality content, such as videos or images, as details in dark or bright areas cannot be fully displayed.

Figure 2 is a schematic plan view of a display panel in a 3D display device provided in an embodiment of the present disclosure. Figure 3 is a schematic view of display pixels in a display panel in a 3D display device provided in an embodiment of the present disclosure. Figure 4 is a schematic view of a local dimming backlight in a 3D display device provided in an embodiment of the present disclosure. Figure 5 is a schematic view of a display panel and a local dimming backlight in a 3D display device provided in an embodiment of the present disclosure. Figure 6 is a schematic view of a display panel in a 3D display device provided in an embodiment of the present disclosure.

[0039] As shown in FIG1 to FIG6 , an embodiment of the present disclosure provides a 3D display device, including: a display panel 101 , a panel driving component 102 , a local dimming backlight 103 , a backlight driving component 104 , a 3D display component 105 , and a brightness adjustment component 106 .

[0040] For example, as shown in FIG. 1 , the display panel 101 and the local dimming backlight 103 are stacked in a direction Z.

[0041] As shown in Fig. 1 , the display panel 101 has a display side DS and a non-display side NDS opposite to the display side DS. In Fig. 1 , the side of the display panel 101 facing away from the local dimming backlight 103 is the display side DS.

[0042] For example, as shown in FIG2 , a display panel 101 includes a plurality of display pixels 1011. A panel driver 102 is configured to provide display data to the plurality of display pixels 1011. For example, as shown in FIG2 , the panel driver 102 includes a data driver DR1 and a gate driver DR2. For example, the data driver DR1 may be a chip. For example, the gate driver DR2 may be a chip or a gate driver on array (GOA).

[0043] For example, as shown in Figures 2 and 3, the display panel 101 includes gate lines GL and data lines DL. As shown in Figure 2, the gate lines GL are connected to the gate driver DR2, and the data lines DL are connected to the data driver DR1. As shown in Figures 2 and 3, the data driver DR1 provides data signals, such as data voltages, to the display pixels 1011 via the data lines DL. The gate driver DR2 provides gate signals, such as scan signals, to the display pixels 1011 via the gate lines GL.

[0044] For clarity of illustration, FIG2 does not show all the gate lines GL, but only schematically shows two gate lines GL. It can be understood that each row of display pixels 1011 is connected to one gate line GL.

[0045] For clarity of illustration, FIG2 does not show all the data lines DL, but only schematically shows two data lines DL. It can be understood that each column of display pixels 1011 is connected to one data line DL.

[0046] 2 , the gate lines GL extend along direction X, and the data lines DL extend along direction Y. The gate lines GL and the data lines DL are insulated from each other and intersect to define a plurality of display pixels 1011 .

[0047] As shown in FIG3 , a display pixel 1011 includes a thin-film transistor (TFT) and a first electrode E1 connected to the thin-film transistor (TFT). The first electrode E1 and the second electrode E2 are configured to form an electric field to drive the liquid crystal in the liquid crystal layer of the display panel to rotate to achieve display. For example, the first electrode E1 and the second electrode E2 may respectively constitute the two plates of the storage capacitor Cst. The second electrode E2 is configured to apply a common voltage Vcom to the display pixel 1011. When the gate line GL and the data line DL apply a gate signal and a data signal to the display pixel 1011, respectively, the voltage on the data line DL is transmitted to the first electrode E1 through the turned-on thin-film transistor TFT. The first electrode E1 may also be referred to as a pixel electrode, and the second electrode E2 may also be referred to as a common electrode.

[0048] Generally speaking, the display panel can be a liquid crystal display panel. For example, as shown in Figure 1, the display panel may include an upper substrate 161, a lower substrate 162, and a liquid crystal layer 163 located between the upper substrate 161 and the lower substrate 162. The lower substrate 162 may be an array substrate, and the thin-film transistor TFT and the first electrode E1 may be disposed on the lower substrate 162. The second electrode E2 may be disposed on the lower substrate 162 or on the upper substrate 161. The upper substrate 161 may be provided with a color filter layer, such as a color filter substrate, but is not limited thereto. Of course, the embodiments of the present disclosure do not limit the specific structures of the display panel and the liquid crystal display panel, and may be selected as needed.

[0049] As shown in FIG1 , the local dimming backlight 103 is configured to provide backlight to the display panel 101 and is located on the non-display side NDS of the display panel 101. As shown in FIG4 to FIG6 , the local dimming backlight 103 includes multiple light-emitting units 1032. The local dimming backlight 103 includes multiple subareas 1031, and each subarea 1031 includes at least one light-emitting unit 1032 from the multiple light-emitting units 1032. For example, a subarea 1031 may include four light-emitting units 1032, but this is not limited to this and can be determined as needed. For example, a subarea 1031 may correspond to multiple display pixels 1011. For example, the light-emitting unit 1032 is a Mini LED, but this is not limited to this and can be set as needed. Multiple subareas 1031 can be independently controlled. The light-emitting units 1032 within a subarea 1031 can be illuminated simultaneously. For clarity of illustration, FIG4 only shows the light-emitting units 1032 within two subareas, and does not show the light-emitting units 1032 in the remaining subareas. The arrangement of the light-emitting units 1032 in the remaining partitions may refer to the arrangement of the light-emitting units 1032 in the illustrated partition.

[0050] For example, the local dimming backlight 103 includes a backplane with a Mini LED matrix. The backplane may include FPC, FRC4, glass, etc., and other suitable backplanes may also be used. The local dimming backlight 103 may also include optical components such as reflectors, diffusers, fluorescent films, and quantum dot (QD) films.

[0051] For example, as shown in FIG2 , the plurality of display pixels 1011 includes a first color display pixel 111, a second color display pixel 112, and a third color display pixel 113. One first color display pixel 111, one second color display pixel 112, and one third color display pixel 113 may constitute one pixel PX. For example, the first color display pixel 111, the second color display pixel 112, and the third color display pixel 113 may be a red display pixel, a green display pixel, and a blue display pixel, respectively. For example, one partition 1031 may correspond to multiple pixels PX. For example, one partition 1031 may correspond to a 16×16 or 32×32 pixel PX array. The plurality of display pixels 1011 is not limited to the above description and may be determined as needed.

[0052] For example, as shown in FIG. 2 , the backlight driving component 104 is configured to provide backlight data to a plurality of light emitting units 1032 , and is configured to drive the local dimming backlight 103 according to a plurality of partitions 1031 .

[0053] 1 , the 3D display unit 105 is configured to enable the display panel 101 to perform 3D display. For example, the 3D display unit 105 includes any one of a lens, a liquid crystal lens, and a parallax barrier, but is not limited thereto, as long as it enables the display panel 101 to perform 3D display.

[0054] The embodiments of the present disclosure use local dimming backlight to improve the contrast of LCDs based on 3D display. These LCDs based on 3D display technology include lens type, lens plus liquid crystal type, parallax barrier, etc., which rely on the backlight system to achieve 3D display.

[0055] For example, in a 3D display device provided by an embodiment of the present disclosure, the 3D display component 105 includes switchable 2D and 3D display components. In this case, the display panel can perform both 2D and 3D displays. For example, when powered off, the 3D display component 105 is inoperative, meaning the display panel 101 performs 2D display. For example, when powered on, the 3D display component 105 is operational, meaning the display panel 101 performs 3D display.

[0056] As shown in FIG6 , the brightness adjustment component 106 is configured to receive display data of 3D display content, calculate and analyze the display data of the 3D display content to extract image brightness data, adjust backlight data based on the image brightness data, and transmit the adjusted backlight data to the backlight driving component 104. The brightness adjustment component 106 can perform image analysis and data processing. The brightness adjustment component 106 can also be referred to as an image analysis processor.

[0057] As shown in Figures 1 and 6, the backlight driving component 104 is further configured to drive the local dimming backlight 103 according to the adjusted backlight data to obtain a combined backlight pattern 130. In other words, the backlight driving component 104 is further configured to drive the local dimming backlight 103 in different regions according to the adjusted backlight data. The backlight driving component 104 is further configured to drive the light-emitting units 1032 in the local dimming backlight 103 in different regions according to the adjusted backlight data. The local dimming backlight 103 provides backlight to the display panel 101 according to the adjusted backlight data.

[0058] The 3D display device provided by the embodiments of the present disclosure adjusts the local dimming backlight 103 based on the 3D display to improve contrast and enhance display quality. The 3D display device provided by the embodiments of the present disclosure improves the contrast of 3D displays based on liquid crystal display panels, and can show better 3D graphics quality. The contrast can be increased from 1000 (optimally 3000-5000) to at least 10000.

[0059] The 3D display device provided by the embodiments of the present disclosure adopts a zone-controllable local dimming backlight and local dimming backlight brightness based on the display content, which can increase the static contrast ratio to more than 10,000 and the dynamic contrast ratio to more than 1,000,000.

[0060] For example, as shown in FIG1 , in a 3D display device provided according to an embodiment of the present disclosure, the 3D display content includes a first image 301 and a second image 302, and the backlight driving component 104 is configured so that the adjusted backlight data (the combined backlight pattern 130) corresponds to the first image 301 and the second image 302. That is, when displaying the first image 301, the local dimming backlight 103 uses the adjusted backlight data, and when displaying the second image 302, the local dimming backlight 103 also uses the adjusted backlight data. This set of adjusted backlight data corresponds to the first image 301 and the second image 302. The same set of adjusted backlight data corresponds to the same backlight pattern. The backlight pattern refers to a bright and dark pattern of multiple partitions.

[0061] The 3D display device provided by the embodiment of the present disclosure uses the same set of adjusted backlight data to correspond to the first image 301 and the second image 302 , so as to reduce displayed clipping and halo artifacts and improve display quality.

[0062] For example, in the 3D display device provided by an embodiment of the present disclosure, the brightness adjustment component 106 is configured to adjust the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 to obtain adjusted backlight data. In other words, the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 are combined to obtain a set of adjusted backlight data. In other words, the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 are the same set of backlight data.

[0063] For example, in a 3D display device provided in an embodiment of the present disclosure, the brightness adjustment component 106 is configured to adjust the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 by taking the maximum value or the average value. For each of the multiple partitions, the adjustment can be performed by taking the maximum value or the average value. Of course, in other embodiments, the adjustment can be performed by taking the maximum value for some of the multiple partitions, while the adjustment can be performed by taking the average value for other partitions.

[0064] By taking an average value for adjustment, the halo artifacts of the 3D display image are reduced.

[0065] By taking the maximum value for adjustment, the texture of the 3D display image will be less.

[0066] For example, as shown in FIG1 , in a 3D display device according to an embodiment of the present disclosure, one of a first image 301 and a second image 302 includes a left-eye image, and the other of the first image 301 and the second image 302 includes a right-eye image. The left-eye image and the right-eye image can be combined to form an image for 3D display.

[0067] For example, according to the 3D display device provided by the embodiment of the present disclosure, the first image 301 and the second image 302 are configured to form an interlaced image, which is an image for 3D display.

[0068] For example, according to the 3D display device provided by the embodiment of the present disclosure, the adjusted backlight data corresponds to a combined backlight pattern. The combined backlight pattern is applied to the display of the left-eye image and the right-eye image. The left-eye image and the right-eye image use the same combined backlight pattern. That is, the left-eye image and the right-eye image share the same backlight pattern. That is, the left and right eye images use the same combined backlight pattern. The embodiment of the present disclosure searches for the optimal local dimming backlight pattern for 3D display by setting the brightness adjustment component 106.

[0069] For example, as shown in FIG1 , in a 3D display device according to an embodiment of the present disclosure, a 3D display component 105 is located on the display side DS of the display panel 101. Of course, in other embodiments, the 3D display component 105 is located between the display panel 101 and the local dimming backlight 103. The embodiments of the present disclosure do not limit the location of the 3D display component 105, as long as it can provide 3D display.

[0070] For example, as shown in FIG6 , in a 3D display device according to an embodiment of the present disclosure, a panel driving component 102 is connected to a display panel 101 , and a backlight driving component 104 is connected to a local dimming backlight 103 .

[0071] For example, as shown in FIG6 , the brightness adjustment component 106 is connected to the panel driving component 102 to obtain display data.

[0072] For example, as shown in FIG6 , the brightness adjustment component 106 is connected to the backlight driving component 104 to transmit the adjusted backlight data.

[0073] For example, according to the 3D display device provided by the embodiment of the present disclosure, the brightness adjustment component 106 includes at least one of a central processing unit (CPU), a system on a chip (SOC), and a field programmable gate array (FPGA) board.

[0074] For example, to further improve contrast, the brightness adjustment component 106 is further configured to adjust display data based on image brightness data and transmit the adjusted display data to the panel driving component 102. The panel driving component 102 is further configured to drive the display panel 101 based on the adjusted display data. By adjusting the display data, the first image and the second image can be further optimized to improve the display contrast.

[0075] Figure 7 is a flow chart of a display method for a 3D display device according to an embodiment of the present disclosure. Figures 8A and 8B are schematic diagrams of a display method for a 3D display device according to an embodiment of the present disclosure. Figures 9A and 9B are schematic diagrams of a display method for a 3D display device according to a comparative example.

[0076] An embodiment of the present disclosure also provides a 3D display method for a 3D display device. As shown in Figures 1 to 6, the 3D display device includes: a display panel 101, including multiple display pixels 1011, having a display side DS and a non-display side NDS opposite to the display side DS; and a local dimming backlight 103, configured to provide backlight to the display panel 101, located on the non-display side NDS of the display panel 101, and including multiple light-emitting units 1032, the local dimming backlight 103 including multiple partitions 1031, each partition 1031 including at least one light-emitting unit 1032 among the multiple light-emitting units 1032.

[0077] As shown in FIG. 1 to FIG. 8B , the 3D display method includes the following steps.

[0078] S1. Use the panel driving component 102 to provide display data to multiple display pixels 1011.

[0079] S2 . Use the backlight driving component 104 to provide backlight data to the plurality of light-emitting units 1032 , and drive the local dimming backlight 103 according to the plurality of partitions 1031 .

[0080] S3. Use the 3D display component 105 to enable the display panel 101 to perform 3D display.

[0081] S4. Use the brightness adjustment component 106 to receive the display data of the 3D display content, calculate and analyze the display data of the 3D display content to extract image brightness data, adjust the backlight data according to the image brightness data, and transmit the adjusted backlight data to the backlight driving component 104.

[0082] S5. Use the backlight driving component 104 to drive the local dimming backlight 103 according to the adjusted backlight data to obtain a combined backlight pattern.

[0083] The 3D display method provided by the embodiments of the present disclosure adjusts the local dimming backlight 103 based on the 3D display to improve contrast and enhance display quality. The 3D display method provided by the embodiments of the present disclosure improves the contrast of 3D displays based on liquid crystal display panels, and can show better 3D graphics quality. The contrast can be increased from 1000 (optimally 3000-5000) to at least 10000.

[0084] In the 3D display method provided by the embodiments of the present disclosure, the brightness adjustment component 106 analyzes the data of the 3D display content, and then calculates the graphic brightness through an algorithm. The backlight driving component 105 outputs the graphic brightness to the Mini LEDs matrix of the local dimming backlight. At the same time, the 3D display content is input to the display, and a static contrast ratio of more than 10,000 and a dynamic contrast ratio of more than 1,000,000 can be obtained, thereby improving the 3D display image quality and performance.

[0085] For example, as shown in FIG1 , according to the 3D display method provided by an embodiment of the present disclosure, the 3D display content includes a first image 301 and a second image 302. The display method further includes causing the adjusted backlight data to correspond to the first image 301 and the second image 302. In the 3D display method provided by an embodiment of the present disclosure, the same set of adjusted backlight data is used to correspond to the first image 301 and the second image 302 to reduce displayed clipping and halo artifacts, thereby improving display quality.

[0086] For example, according to the 3D display method provided in an embodiment of the present disclosure, the 3D display method further includes: using the brightness adjustment component 106 to adjust the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 to obtain adjusted backlight data. In the 3D display method provided in an embodiment of the present disclosure, the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 are the same set of backlight data, corresponding to the same set of backlight patterns.

[0087] For example, according to the 3D display method provided in an embodiment of the present disclosure, the 3D display method further includes: using the brightness adjustment component 106 to adjust the backlight data corresponding to the first image 301 of the local dimming backlight 103 and the backlight data corresponding to the second image 302 of the local dimming backlight 103 by taking the maximum value or the average value. In the 3D display method provided in an embodiment of the present disclosure, taking the average value for adjustment reduces halo artifacts in the 3D displayed image. In the 3D display method provided in an embodiment of the present disclosure, taking the maximum value for adjustment reduces texture in the 3D displayed image.

[0088] For example, according to the 3D display method provided by an embodiment of the present disclosure, one of the first image 301 and the second image 302 includes a left-eye image, and the other of the first image 301 and the second image 302 includes a right-eye image. The left-eye image and the right-eye image can be combined into an image for 3D display.

[0089] For example, according to the 3D display method provided by the embodiment of the present disclosure, the first image 301 and the second image 302 form an interleaved image. The interleaved image is an image for 3D display.

[0090] For example, in the 3D display method provided by the embodiment of the present disclosure, the first image 301 and the second image 302 may be displayed in a time-sharing manner. For example, the first image 301 is displayed in a first time period, and the second image 302 is displayed in a second time period.

[0091] For example, according to the 3D display method provided by the embodiments of the present disclosure, the adjusted backlight data corresponds to a combined backlight pattern. That is, the backlight driver 104 drives the local dimming backlight 103 according to the adjusted backlight data to obtain a combined backlight pattern. For example, a first image 301 is displayed during a first time period, and a second image 302 is displayed during a second time period, and the same set of backlight patterns, i.e., the combined backlight pattern, is used in both the first and second time periods.

[0092] For example, according to the 3D display method provided by an embodiment of the present disclosure, the adjusted backlight data corresponds to a combined backlight pattern. The combined backlight pattern is applied to the display of the left-eye image and the right-eye image. The left-eye image and the right-eye image use the same combined backlight pattern. That is, the left-eye image and the right-eye image share the same backlight pattern. That is, the left and right eye images use the same combined backlight pattern. The embodiment of the present disclosure searches for the optimal local dimming backlight pattern for 3D display by setting a brightness adjustment component 106.

[0093] An embodiment of the present disclosure provides a 3D display method, which includes the following steps.

[0094] S11 , obtaining an image RGB data stream of 3D display content.

[0095] S12. Convert the data stream of each color component in the RGB data stream of the processed image.

[0096] S13. Calculate and analyze RGB data to extract image brightness data.

[0097] S14 , outputting the processed 3D image RGB data stream to a display panel of a liquid crystal display device.

[0098] S15 , outputting the driving value to the local dimming backlight 103 .

[0099] An embodiment of the present disclosure provides a 3D display method for a 3D display device, wherein the 3D display device includes a display panel and a local dimming backlight. The display panel may be a 27-inch, 4K (3860*2160) display panel with a 60HZ driver, and the local dimming backlight has 2306 areas, each area having 4 Mini LEDs. An FPGA board may be used to receive and analyze 3D image brightness data. A switchable 3D display component may be used and disposed above the display panel to achieve switchable 2D / 3D display. In 2D mode, high contrast may be achieved by utilizing local dimming, and in 3D mode, high contrast may be achieved by using the device or method provided in the embodiment of the present disclosure.

[0100] For example, according to the 3D display method provided by the embodiment of the present disclosure, the 3D display component 105 includes switchable 2D and 3D display components.

[0101] For example, according to the 3D display method provided by the embodiment of the present disclosure, the brightness adjustment component 106 includes at least one of a central processing unit, a system-on-chip, and a field programmable gate array.

[0102] For example, to further improve contrast, the 3D display method provided in accordance with an embodiment of the present disclosure further includes using a brightness adjustment component 106 to adjust display data based on image brightness data, transmitting the adjusted display data to a panel driver component 102, and using the panel driver component 102 to drive the display panel 101 based on the adjusted display data. By adjusting the display data, the first image and the second image can be further optimized to improve the display contrast.

[0103] In the 3D display device and the 3D display method provided by the embodiments of the present disclosure, multi-viewing angle display may also be formed, whereby the multi-viewing angle display replaces the stereoscopic display to obtain a better contrast at multiple viewing angles.

[0104] As shown in Figures 9A and 9B , in a display method provided in a comparative example, a first image corresponds to one backlight pattern, and a second image corresponds to another backlight pattern. One of the first and second images can be a left-eye image, and the other can be a right-eye image. In the display device or display method shown in Figures 9A and 9B , in the interleaved image obtained from the first and second images, adjacent pixels correspond to different viewing angles and have different brightnesses, particularly in high-disparity areas. Furthermore, high-frequency patterns can easily interfere with standard 2D local dimming algorithms and ruin the results. Consequently, the display device or display method shown in Figures 9A and 9B cannot produce a high-contrast 3D display image. Figures 9A and 9B omit the 3D display components in the display device.

[0105] Therefore, the embodiments of the present disclosure provide a display device and method that can improve contrast.

[0106] For example, in some embodiments of the present disclosure, the brightness adjustment component 106 may only include a backlight brightness adjustment component, without having to adjust the brightness of the image displayed on the display panel. Of course, in other embodiments of the present disclosure, the brightness adjustment component 106 includes not only a backlight brightness adjustment component but also a panel brightness adjustment component, thereby adjusting the brightness of the image displayed on the display panel.

[0107] For example, in an embodiment of the present disclosure, as shown in FIG. 2 , the display pixels 1011 are arranged in an array along directions X and Y.

[0108] For example, in an embodiment of the present disclosure, as shown in Figure 4 , the partitions 1031 are arranged in an array along directions X and Y. For example, the light emitting units 1032 are arranged in an array along directions X and Y.

[0109] Directions X and Y are both parallel to the main surface of base substrate BS. The main surface of base substrate BS is the surface used to fabricate various components. For example, directions X and Y intersect. Furthermore, for example, directions X and Y are perpendicular. Direction Z is perpendicular to the main surface of base substrate BS. Direction Z is perpendicular to direction X and also perpendicular to direction Y.

[0110] The brightness adjustment component 106 of the embodiment of the present disclosure may also include one or more processors and one or more memories. The processor can process data signals and may include various computing structures, such as a complex instruction set computer (CISC) structure, a reduced instruction set computer (RISC) structure, or a structure that implements a combination of multiple instruction sets. The memory can store instructions and / or data executed by the processor. These instructions and / or data may include code for implementing some or all functions of one or more devices described in the embodiment of the present disclosure. For example, the memory includes a dynamic random access memory (DRAM), a static random access memory (SRAM), a flash memory, an optical memory, or other memories well known to those skilled in the art.

[0111] In some embodiments of the present disclosure, the brightness adjustment component 106 includes codes and programs stored in a memory; a processor may execute the codes and programs to implement some or all functions of the brightness adjustment component 106 as described above.

[0112] In some embodiments of the present disclosure, the brightness adjustment component 106 may be a special hardware device that implements some or all of the functions of the brightness adjustment component 106 described above. For example, the brightness adjustment component 106 may be a circuit board or a combination of multiple circuit boards that implement the functions described above. In embodiments of the present disclosure, the circuit board or the combination of multiple circuit boards may include: (1) one or more processors; (2) one or more non-transitory computer-readable memories connected to the processors; and (3) firmware stored in the memories that is executable by the processors.

[0113] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
