Description
Technical Field
[0001] The present application relates to the field of display screens, and in particular to a display method, an electronic device, and a storage medium. Background Art
[0002] Head-mounted display technology is usually used in the following three scenarios: Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR).
[0003] Among them, the display screen based on silicon-based OLED backplane can be compatible with small and light dimensions and high resolution due to its ultra-high pixel density, and it has the advantages of high color gamut and high brightness. Therefore, it is increasingly favored by the industry's mainstream flagship head-mounted display products. However, since the silicon-based OLED backplane uses semiconductor technology, the larger the area of the silicon-based product, the greater the cost. For VR electronic devices or MR electronic devices that require a large field of view (FOV), the display screen area required is large, so the cost is extremely high, which is not conducive to large-scale commercial use.
[0004] LCD backplanes are made of glass and use the inexpensive LTPS process, which is much cheaper than silicon-based backplanes. However, due to the process limitations of LTPS materials, the pixel density of displays based on LCD backplanes is relatively low. For example, the current mass production limit of pixel density of displays based on LCD backplanes can only reach 1200PPI. However, the pixel density of high-end MR products is required to reach 2100PPI. It can be seen that although the cost of using LCD backplanes is relatively low, under the current process, due to the low pixel density, the required resolution cannot be achieved. Therefore, a display method is urgently needed so that the LCD display can meet the resolution requirements under the current process. Summary of the invention

[0011] In one possible implementation manner, the number of backlight partitions is determined by a resolution.
[0012] In one possible implementation, a proportion of a total lighting time of all colors corresponding to the multiple backlight partitions in one frame is less than a preset ratio.

[0034] Head-mounted display technology is usually used in the following three scenarios: Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR).
[0035] Among them, the display screen based on silicon-based OLED backplane can be compatible with small and light dimensions and high resolution due to its ultra-high pixel density, and it has the advantages of high color gamut and high brightness. Therefore, it is increasingly favored by the industry's mainstream flagship head-mounted display products. However, since the silicon-based OLED backplane uses semiconductor technology, the larger the area of the silicon-based product, the greater the cost. For VR electronic devices or MR electronic devices that require a large field of view (FOV), the display screen area required is large, so the cost is extremely high, which is not conducive to large-scale commercial use.
[0036] LCD backplanes are made of glass and use the inexpensive LTPS process, which is much cheaper than silicon-based backplanes. However, due to the process limitations of LTPS materials, the pixel density of displays based on LCD backplanes is relatively low. For example, the current mass production limit of pixel density of displays based on LCD backplanes can only reach 1200PPI. However, the pixel density of high-end MR products is required to reach 2100PPI. It can be seen that although the cost of using LCD backplanes is relatively low, under the current process, due to the low pixel density, the required resolution cannot be achieved. Therefore, a display method is urgently needed so that the LCD display can meet the resolution requirements under the current process.
[0037] Based on the above problems, an embodiment of the present application proposes a display method, which is applied to an electronic device, and the electronic device may include an LCD display screen. The electronic device may be a head-mounted display device. A head-mounted display device is a type of electronic device among wearable smart devices. Wearable smart devices are a general term for devices that are intelligently designed and developed for daily wear using wearable technology, such as glasses, gloves, watches, clothing, and shoes. A wearable smart device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable smart devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction.
[0038] In the embodiment of the present application, the head-mounted display device may be smart glasses, a smart helmet, or other devices. The embodiment of the present application does not specifically limit the type of the head-mounted display device.
[0039] Figure 1 First, a schematic structural diagram of the electronic device 100 is shown as an example.
[0040] The electronic device 100 may include at least one processor and at least one memory connected to the processor, wherein the memory stores program instructions that can be executed by the processor, and the processor calls the program instructions to execute the method provided in the embodiment shown in this document.
[0041] Figure 1A block diagram of an exemplary electronic device 100 suitable for implementing embodiments herein is shown. Figure 1 The electronic device 100 shown is merely an example and should not limit the functionality and scope of use of the embodiments of this document.
[0042] like Figure 1 As shown, components of the electronic device 100 may include, but are not limited to: one or more processors 110 , a memory 120 , a communication bus 140 connecting different system components (including the memory 120 and the processor 110 ), and a communication interface 130 .
[0043] The communication bus 140 represents one or more of several types of bus structures, including a memory bus or memory controller, a peripheral bus, a graphics acceleration port, a processor or a local bus using any of a variety of bus structures. For example, these architectures include but are not limited to Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MAC) bus, Enhanced ISA bus, Video Electronics Standards Association (VESA) local bus and Peripheral Component Interconnection (PCI) bus.
[0044] The electronic device 100 typically includes a variety of computer system readable media. These media can be any available media that can be accessed by the device, including volatile and non-volatile media, removable and non-removable media.
[0045] The memory 120 may include computer system readable media in the form of volatile memory, such as random access memory (RAM) and / or cache memory. The device may further include other removable / non-removable, volatile / non-volatile computer system storage media. Figure 1Not shown in the figure, a disk drive for reading and writing a removable non-volatile disk (e.g., a "floppy disk"), and an optical disk drive for reading and writing a removable non-volatile optical disk (e.g., a compact disc read only memory (CD-ROM), a digital versatile disc read only memory (DVD-ROM), or other optical media) may be provided. In these cases, each drive may be connected to the communication bus 140 via one or more data medium interfaces. The memory 120 may include at least one program product having a set (e.g., at least one) of program modules configured to perform the functions of the embodiments herein.
[0046] A program / utility having a set (at least one) of program modules may be stored in memory 120, such program modules including, but not limited to, an operating system, one or more application programs, other program modules, and program data, each of which or some combination may include an implementation of a network environment. The program modules generally perform the functions and / or methods of the embodiments described herein.
[0047] The electronic device 100 may also communicate with one or more external devices (e.g., keyboard, pointing device, display, etc.), one or more devices that enable a user to interact with the device, and / or any device that enables the device to communicate with one or more other devices (e.g., network card, modem, etc.). Such communication may be performed via the communication interface 130. Furthermore, the electronic device 100 may also communicate with the network adapter ( Figure 1 The network adapter can communicate with one or more networks (such as a local area network (LAN), a wide area network (WAN), and / or a public network, such as the Internet) through the communication bus 140. It should be understood that although Figure 1 Not shown, other hardware and / or software modules may be used in conjunction with the electronic device 100, including but not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, disk arrays (Redundant Arrays of Independent Drives; hereinafter referred to as: RAID) systems, tape drives, and data backup storage systems.
[0048] The processor 110 executes various functional applications and data processing by running the programs stored in the memory 120, such as implementing the methods provided in the embodiments of this document.
[0049] It is understandable that the interface connection relationship between the modules illustrated in the embodiments of this document is only for illustrative purposes and does not constitute a structural limitation on the electronic device 100. In other embodiments of this document, the electronic device 100 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.
[0050] Next, combine Figure 2-Figure 9 The display method provided in the embodiment of the present application is described.
[0051] Figure 2 Displays schematics for existing LCDs. Figure 2 The existing LCD display screen 200 includes a backlight 201, a polarizer 202, a glass 203, a pixel circuit 204, a liquid crystal 205, a color filter 206, a glass 207 and a polarizer 208.
[0052] The backlight 201 uses a white LED backlight and is matched with a color filter 206 to achieve LCD color display.
[0053] It is understandable that the colorization of a pixel can be realized by sub-pixels of multiple colors, and the sub-pixels of multiple colors can include sub-pixels of three colors, namely red (R), green (G) and blue (B), wherein each sub-pixel requires a separate pixel circuit 204 to control the flip angle of the liquid crystal 205 to achieve different brightness, and the corresponding color filter 206 is matched above to achieve colorization. If white is required to be displayed, one sub-pixel of each of the three colors of RGB needs to be lit at the same time, that is, one pixel can be realized by three sub-pixels of different colors.
[0054] Figure 3 This is a schematic diagram of an LCD display provided by an embodiment of the present application. Figure 3 The LCD display screen 300 of the present application includes a backlight 301, a polarizer 302, a glass 303, a pixel circuit 304, a liquid crystal 305, a glass 306 and a polarizer 307.
[0055] Among them, the backlight 301 adopts red LED backlight, green LED backlight and blue LED backlight to replace the existing white LED backlight, and the LCD display screen 300 of the present application does not need a color filter, that is, one pixel only needs one pixel circuit to support the color display of one pixel. In other words, in the LCD display scheme in the embodiment of the present application, there is no sub-pixel, or in the pixel circuit design, one main pixel is equivalent to one sub-pixel. Compared with the display scheme of the existing LCD display screen, one pixel in the existing LCD display screen requires pixel circuits corresponding to three sub-pixels of different colors to support the color display of the pixel, while one pixel in the LCD display screen of the present application only needs a pixel circuit corresponding to one sub-pixel to support the color display of the pixel. It can be seen that compared with the existing LCD display scheme, the LCD display scheme of the present application can greatly reduce the pixel circuit while ensuring the same pixel density. In other words, under the condition of the same pixel circuit, the pixel density can be greatly improved.
[0056] For example, taking a 2.1-inch LCD as an example, if an existing LCD wants to achieve a resolution of 3840, 3840*3 pixel circuits are required in the horizontal direction, while the LCD of the present application only needs 3840*1 pixel circuit, which can greatly reduce the process level of the pixel density corresponding to the pixel circuit from the required 2100PPI to 700PPI. In this way, the resolution can be improved on the basis of the existing process level (for example, the existing process level can only reach 1200PPI), thereby realizing large-scale commercial use.
[0057] like Figure 4 The figure is a flow chart of an embodiment of the display method provided by the present application. Figure 4 In the embodiment shown, the backlight lighting sequence can be set by the display method to achieve the purpose of improving the resolution, which specifically includes the following steps:
[0058] Step 401, lighting up the backlight in sequence according to the color sequence in the target sequence combination, the target sequence combination is any sequence combination among a plurality of sequence combinations, and the plurality of sequence combinations are a plurality of combinations consisting of any sequence of red, green and blue.
[0059] Specifically, there may be multiple sequential combinations consisting of any order of red, green and blue. For example, the multiple sequential combinations may include sequential combination 1, sequential combination 2, sequential combination 3, sequential combination 4, sequential combination 5 and sequential combination 6.
[0060] Among them, sequence combination 1 can be the order of red->green->blue, that is, the order can be to light up red first, then green, and finally blue. Sequence combination 2 can be the order of red->blue->green, that is, the order can be to light up red first, then blue, and finally green. Sequence combination 3 can be the order of green->red->blue, that is, the order can be to light up green first, then red, and finally blue. Sequence combination 4 can be the order of green->blue->red, that is, the order can be to light up green first, then blue, and finally red. Sequence combination 5 can be the order of blue->green->red, that is, the order can be to light up blue first, then green, and finally red. Sequence combination 6 can be the order of blue->red->green, that is, the order can be to light up blue first, then red, and finally green.
[0061] Next, any one of the above sequence combinations can be selected as the backlight lighting sequence to light up the various colors in the backlight in sequence. Figure 5 For example, after determining that sequence combination 1 is the target sequence combination, you can follow the order of sequence combination 1 to Figure 5 The backlight in various colors lights up.
[0062] in, Figure 5 A schematic diagram of a backlight provided in an embodiment of the present application. Figure 5 The backlight 500 includes three colors of backlights, namely, red LED backlight, green LED backlight and blue LED backlight. The order of sequentially lighting up the backlights of various colors in the backlight 500 may be: first, all the red LED backlights in the backlight 500 are lit up, then all the green LED backlights in the backlight 500 are lit up, and finally all the blue LED backlights in the backlight 500 are lit up.
[0063] In some optional embodiments, in order to avoid the problem of smearing, the backlight 500 may be partitioned, thereby obtaining a plurality of backlight partitions, and each backlight partition may be lit up in sequence according to the color sequence in the sequential combination.
[0064] The number of backlights corresponding to each backlight subarea may be the same, or the number of backlights corresponding to each backlight subarea may be different, which is not particularly limited in the embodiment of the present application.
[0065] In some optional embodiments, the number of backlight partitions can be determined according to the resolution. It is understandable that the resolution determines the number of rows of pixels. If the number of rows of pixels is divisible by the number of backlight partitions, the number of rows of pixels corresponding to each backlight partition is uniform, and it is relatively easy to calculate the voltage and current parameters of each backlight partition. For example, the voltage and current parameters of each backlight partition can be the same, so the complexity and amount of calculation can be reduced; if the number of rows of pixels cannot be divided by the number of backlight partitions, it will cause the number of rows of pixels corresponding to the backlight partitions to be uneven, and it is relatively complicated to calculate the voltage and current parameters of each backlight partition. For example, the voltage and current parameters of each backlight partition can be different, so the complexity and amount of calculation will increase. Therefore, when selecting the number of backlight partitions, you can select a value that the number of rows of pixels can be divided by the number of backlight partitions.
[0066] It can be understood that when the number of pixel rows cannot be divided evenly by the number of backlight partitions, the number of pixel rows corresponding to at least one backlight partition among the multiple backlight partitions is different from that of the remaining backlight partitions.
[0067] For example, assuming that the resolution is 3840, that is, the number of rows of pixels is 3840, if the number of backlight partitions is selected to be 7, that is, the number of backlight partitions is 7, for example, the 7 backlight partitions may be backlight partition 1 to backlight partition 7, and since 3840 cannot be divided by 7, at least one backlight partition among backlight partition 1 to backlight partition 7 may have a different number of rows of pixels corresponding to the remaining backlight partitions. For example, the number of rows of pixels corresponding to backlight partitions 1 to backlight partition 6 may be the same, and the number of rows of pixels corresponding to backlight partition 7 and backlight partition 1 to backlight partition 6 may be different, wherein the number of rows of pixels corresponding to each backlight partition among backlight partition 1 to backlight partition 6 may be 550, and the number of rows of pixels corresponding to backlight partition 7 may be 540. Alternatively, the number of rows of pixels corresponding to backlight partitions 2 to 7 may be the same, and the number of rows of pixels corresponding to backlight partition 1 is different from that of backlight partition 2 to 7, wherein the number of rows of pixels corresponding to each of backlight partitions 2 to 7 may be 550, and the number of rows of pixels corresponding to backlight partition 1 may be 540. Alternatively, the number of rows of pixels corresponding to backlight partitions 1 to 3, backlight partitions 5 to 7 and therebetween may be the same, and the number of rows of pixels corresponding to backlight partition 4 and backlight partitions 1 to 3, backlight partitions 5 to 7 is different, wherein the number of rows of pixels corresponding to each of backlight partitions 1 to 3, backlight partitions 5 to 7 may be 550, and the number of rows of pixels corresponding to backlight partition 4 may be 540. Alternatively, the number of rows of pixels corresponding to backlight partitions 1 to backlight partition 5 may be the same, and the number of rows of pixels corresponding to backlight partitions 6 and 7 may be different from the number of rows of pixels corresponding to backlight partitions 1 to backlight partition 5, wherein the number of rows of pixels corresponding to each backlight partition in backlight partition 1 to backlight partition 5 may be 550, and the number of rows of pixels corresponding to backlight partitions 6 and 7 may be 545.
[0068] It can be understood that the row value of pixels corresponding to each backlight partition in the above embodiments is only for illustrative purposes and does not constitute a limitation on the embodiments of the present application. In some embodiments, the row value of pixels corresponding to each backlight partition in the above embodiments may also be other values.
[0069] For another example, assuming the resolution is 3840, that is, the number of rows of pixels is 3840, if the number of backlight partitions is selected as 6, that is, the number of backlight partitions is 6, for example, the 6 backlight partitions can be backlight partition 1-backlight partition 6. Since 3840 is divisible by 6, the number of rows of pixels corresponding to each backlight partition in backlight partition 1-backlight partition 6 can be the same, that is, the number of rows of pixels corresponding to each backlight partition is 3840 / 6=640.
[0070] Next, Figure 5 Take 2 as an example to illustrate. Figure 5Based on the backlight shown, it can be partitioned, thus obtaining Figure 6 Backlight schematic diagram shown. Figure 6 The backlight 600 includes a plurality of backlight partitions. For example, the plurality of backlight partitions may include a backlight partition 601 , a backlight partition 602 , a backlight partition 603 , a backlight partition 604 , a backlight partition 605 and a backlight partition 606 .
[0071] It can be understood that the above-mentioned 6 backlight partitions are only exemplary illustrations and do not constitute a limitation on the embodiments of the present application. In some embodiments, the backlight partitions may be less than 6 or more than 6.
[0072] After obtaining multiple backlight partitions, the backlight partitions corresponding to the various colors can be lit up in sequence according to the sequence combination. Figure 6 For example, the method of sequentially lighting up each backlight partition corresponding to each color can be: first, sequentially light up each backlight partition corresponding to the red backlight, that is, starting from backlight partition 601 and ending at backlight partition 606, light up the red backlight in each backlight partition in sequence. Next, sequentially light up each backlight partition corresponding to the green backlight, that is, starting from backlight partition 601 and ending at backlight partition 606, light up the green backlight in each backlight partition in sequence. Finally, sequentially light up each backlight partition corresponding to the blue backlight, that is, starting from backlight partition 601 and ending at backlight partition 606, light up the green backlight in each backlight partition in sequence. That is to say, taking the 6 backlight partitions in the above embodiment as an example, each color of the backlight is lit 6 times, and the backlight of the three colors is lit 18 times in total.
[0073] It is understandable that the position of the backlight can be directly below or to the side of the display screen, and the embodiments of the present application do not specifically limit this. The order in which the backlight is turned on can correspond to the scanning direction. Among them, the scanning direction can be a direction perpendicular to the display driver chip (Display Driver IC, DDIC). The starting position of the scanning direction can be a side close to the DDIC, and the ending position of the scanning direction can be a side away from the DDIC. The order in which the backlight is turned on can be to light up the backlight partition on the side close to the DDIC first, and then light up the backlight partition on the side away from the DDIC, that is, to light up the backlight partitions in sequence along the scanning direction.
[0074] Figure 7 This is a schematic diagram of the scanning direction and lighting sequence. Take the resolution of 3840 as an example. Figure 7, since the resolution is 3840, that is, the display area has 3840 rows of pixels. Among them, the row of pixels closest to the DDIC can be considered as the first row of pixels, and the row of pixels farthest from the DDIC can be considered as the last row of pixels, that is, the 3840th row of pixels, and the scanning direction can be from the first row of pixels to the 3840th row of pixels.
[0075] The lighting order may be to light up the backlight partition corresponding to the first row of pixels, and then light up each backlight partition in sequence along the scanning direction until the backlight partition corresponding to the 3840th row of pixels is lit. Taking 6 backlight partitions as an example, namely backlight partition 1 to backlight partition 6, assuming that the backlight partition corresponding to the first row of pixels is backlight partition 1, and the backlight partition corresponding to the 3840th row of pixels is backlight partition 6, the lighting order may be to light up backlight partition 1 to backlight partition 6 in sequence.
[0076] Figure 8 This is the timing diagram of backlight lighting. Take 6 backlight partitions as an example, refer to Figure 8 , each color of backlight is lit up 6 times. Among them, each backlight partition corresponding to each color of backlight is continuously lit for a certain time, and there will be a certain time interval between the lighting moments of each backlight partition. For example, taking the 6 backlight partitions corresponding to the red backlight as an example, the red backlight in backlight partition 1 is first lit, and the red backlight in backlight partition 2 is lit after a certain time interval, and then the red backlight in backlight partition 3 is lit after a certain time interval, and so on, until the red backlight in backlight partition 7 is lit. At this time, the red backlight is lit up, and then the backlight partitions of the green backlight are lit up. Among them, the lighting method of each backlight partition of the green backlight is specifically referred to the lighting method of each backlight partition of the red backlight, which will not be repeated here. After lighting up each backlight partition of the green backlight, finally light up each backlight partition of the blue backlight. The lighting method of each backlight partition of the blue backlight refers specifically to the lighting method of each backlight partition of the red backlight, which will not be repeated here.
[0077] Refer to Figure 8, each backlight partition of each color can correspond to the pixels in each part of the display area. Since the backlight is divided into 6 backlight partitions, each backlight partition can correspond to 640 rows of pixels. Taking the red backlight as an example, the backlight partition 1 of the red backlight corresponds to the 1st to 640th rows of pixels in the display area, that is, the 1st to 640th rows of pixels in the display area can be illuminated by the backlight partition 1 of the red backlight; the backlight partition 2 of the red backlight corresponds to the 641st to 1280th rows of pixels in the display area, that is, the 641st to 1280th rows of pixels in the display area can be illuminated by the backlight partition 2 of the red backlight; the backlight partition 3 of the red backlight corresponds to the 1281st to 1920th rows of pixels in the display area, that is, the 1281st to 1920th rows of pixels in the display area can be illuminated by the backlight partition 3 of the red backlight; Backlight partition 4 of the red backlight corresponds to the 1921st to 2560th rows of pixels in the display area, that is, the 1921st to 2560th rows of pixels in the display area can be illuminated by the backlight partition 4 of the red backlight; backlight partition 5 of the red backlight corresponds to the 2561st to 3200th rows of pixels in the display area, that is, the 2561st to 3200th rows of pixels in the display area can be illuminated by the backlight partition 5 of the red backlight; backlight partition 6 of the red backlight corresponds to the 3201st to 3840th rows of pixels in the display area, that is, the 3201st to 3840th rows of pixels in the display area can be illuminated by the backlight partition 2 of the red backlight.
[0078] It is understandable that the timing of lighting up the green backlight and the blue backlight can specifically refer to the timing of lighting up the red backlight, which will not be described in detail here.
[0079] In some optional embodiments, in order to better avoid the problem of smearing, it can also be achieved by setting the lighting duration. It can be understood that within 1 frame, the red backlight, green backlight and blue backlight all have a lighting duration and a long dark duration, that is, within 1 frame, the red backlight, green backlight and blue backlight can be long bright in a period of time, and can be long dark in another period of time. Among them, the total lighting duration of the red backlight, green backlight and blue backlight can account for less than the preset ratio. Exemplarily, the preset ratio can be 0.5, that is, the total lighting duration of the red backlight, green backlight and blue backlight can be less than 0.5 frames. Assuming that the lighting duration of the red backlight is duration 1, the lighting duration of the green backlight is duration 2, and the lighting duration of the blue backlight is duration 3, then duration 1+duration 2+duration 3<0.5 frame.
[0080] It can be understood that the above-mentioned preset ratio value is only for illustrative purposes and does not constitute a limitation on the embodiments of the present application. In some embodiments, the preset ratio value may also be other values.
[0081] Fig. 9This is a schematic diagram of the duration ratio provided in the embodiment of the present application. Fig. 9 , taking the preset ratio value of 0.5 as an example, the red backlight, green backlight and blue backlight are lit up in one frame, among which the red backlight is lit up for duration 1, the green backlight is lit up for duration 2, and the blue backlight is lit up for duration 3, then the total lighting duration = duration 1 + duration 2 + duration 3. In order to avoid the problem of ghosting, the proportion of the total lighting duration can be set to less than 0.5, that is, duration 1 + duration 2 + duration 3 < 0.5 frames.
