Description

Technical Field

[0001] The present invention relates to the technical field of display panel display, and particularly to a display control method, system and display panel. Background Art

[0002] In the field of display panel display, the application of Demura (Display Mura Correction) technology and Deburn in (Display Burn-in Correction) technology can improve the display effect and lifespan of display panels.

[0003] Currently, the data stored for Deburn in requirements is generally the lighting duration of each pixel, and the data stored for Demura requirements is generally the compensation parameters of each pixel. The two are stored in the storage space. When in use, according to the set requirements, the respective occupied space sizes of the two are pre-allocated and remain unchanged throughout the usage cycle.

[0004] However, the compensation requirements for Deburn in and Demura of the display panel are different during the usage cycle. For example, in the early stage of the display panel's use, the burn-in phenomenon is not very serious, so the Demura compensation effect is higher. In the later stage of the display panel's use, when the burn-in phenomenon of the display panel is serious, the Deburn in compensation effect is higher.

[0005] Therefore, keeping the storage space for the lighting duration and compensation parameters unchanged throughout the usage cycle in the prior art cannot achieve a better display effect. Summary of the Invention

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after without special instructions.

[0027] SRAM (Static Random-Access Memory) is a storage space that can be read quickly. It is often used as a temporary data storage space in OLED DDIC (OLED, Organic Light-Emitting Diode, and DDIC, Display Driver Integrated Circuit). However, its manufacturing cost is relatively high. Therefore, the SRAM space in DDIC is limited. Both Deburn IN and Demura, these two commonly used technologies for improving key visual effects, require storing certain data in the SRAM of DDIC after power-on.

[0028] The data required to be stored by the Deburn in technology is generally the lighting duration of each pixel. Generally, to ensure recording the entire usage cycle time length of the pixel, the bit width of a single duration record value is at least 32 bits. In the early stage of use, that is, when the lighting duration is short, only the low bit of the 32-bit width record value is valid. The longer the lighting time, the more valid bits the record value has.

[0029] The data required to be stored by the Demura technology is generally the compensation value of each pixel. Generally, a single compensation value is 8 bits, but it is stored in blocks, such as 2x1, that is, 2 pixels share a compensation value. Generally, the larger the block, the worse the Demura compensation effect.

[0030] The current SRAM space management is static. That is, according to the technical setting requirements, the space sizes occupied by the lighting duration and the compensation value are pre-allocated, and these space sizes will not change during the entire usage cycle. For example, without using the Deburn in technology, Demura supports 1x1 Blocks, and when using the Deburn in technology, Demura can only support 4x4 Blocks, and it cannot be dynamically adjusted according to the usage of the display panel. This results in the compensation effects of the two technologies not being able to match the usage status of the display panel to achieve the best results. If the Deburn IN technology is used, the Demura Blocks are too large, resulting in a necessarily poor effect. And if the better compensation effect of Demura is selected, the Deburn IN technology must be abandoned.

[0031] However, in fact, the compensation requirements for the Deburn in and Demura technologies during the usage cycle of the screen are different. For example, in the early stage of using the display panel, the burn-in phenomenon is not very serious, so the compensation effect for the Demura technology is higher, and a larger storage space should be given to the Demura technology. In the later stage, the screen burn-in phenomenon is serious, so the compensation effect for the Deburn in technology is higher, and a larger storage space should be given to the Deburn in technology. However, the current SRAM space management scheme does not support this, resulting in the visual effect improvement not being able to guarantee the best effect.

[0032] For the above reasons, the embodiments of the present application provide a display control method, system, and display panel, which can dynamically allocate storage space for the lighting duration and display compensation parameters, so as to be able to perform compensations with different requirements for the lighting duration and display compensation parameters during different display stages of the display panel, and improve the display effect of the display panel.

[0033] Figure 1 The following shows the display control method provided by the embodiments of the present invention, including:

[0034] S101. Obtain the usage time of each pixel in the display panel during the current display cycle;

[0035] S102. Allocate storage space for the display information of each pixel in the display driver chip of the display panel according to the usage time;

[0036] S103. Obtain the display information of each pixel and store it in the storage space, so as to call the display information of each pixel from the storage space to drive each pixel to display in the next display cycle.

[0037] In step S101, the current display cycle is the used cycle of the display panel. During this cycle, each pixel has its usage time, and this usage time can be obtained according to the pixel lighting duration in Deburn in.

[0038] In step S102, the display information includes the lighting duration of the pixels and the display compensation parameters; the storage space includes a first storage space for storing the lighting duration and a second storage space for storing the display compensation parameters.

[0039] In this embodiment, the first storage space and the second storage space are located in an independent storage space outside the DDIC, and the independent storage space can be a Flash memory.

[0040] In step S103, by allocating storage spaces for the lighting duration and the display compensation parameters, the lighting duration and the display compensation parameters can have storage spaces adapted to the usage stage of the display panel.

[0041] Therefore, the display control method provided in this embodiment can allocate storage spaces for the display information of the pixels in the display panel, that is, the lighting duration and the display compensation parameters, according to the usage duration of the pixels, so that the size allocation of the storage spaces of the two is dynamically variable, and thus different requirements for compensation can be performed on the lighting duration and the display compensation parameters in different display stages of the display panel, improving the display effect of the display panel.

[0042] In some embodiments, allocating storage spaces for the display information of each pixel in the display driving chip of the display panel according to the usage time includes:

[0043] Obtaining the proportion of the first pixels among all pixels whose usage time is greater than a first threshold and less than a second threshold; if the proportion of the first pixels is less than a preset percentage, using a first scheme to allocate the second storage space; if the proportion of the first pixels is greater than or equal to the preset percentage, using a second scheme to allocate the second storage space;

[0044] In this embodiment, the first threshold and the second threshold are preset values, and the first threshold is less than the second threshold. For example, the value range of the first threshold is 0 - 1000, and the value range of the second threshold is 1001 - 2000. This embodiment will take the first threshold as 1000 and the second threshold as 2000 as an example for illustration.

[0045] This embodiment can allocate storage spaces for the lighting duration and the display compensation parameters according to the proportion of the first pixels. For example, if the preset percentage is 10%, then when the proportion of the pixels whose usage time is greater than 1000 and less than 2000 among all pixels is less than 10%, the first scheme is used to allocate the second storage space. When the proportion of the pixels whose usage time is greater than 1000 and less than 2000 among all pixels is greater than or equal to 10%, the second scheme is used to allocate the second storage space.

[0046] Among them, the second storage space for storing display compensation parameters in the first scheme is larger than the second storage space for storing display compensation parameters in the second scheme.

[0047] This is because when the first pixel ratio of pixels with a usage time greater than 1000 and less than 2000 among all pixels is less than 10%, it indicates that the display panel has a short usage time. At this time, the storage space occupied by the lighting duration is small. Therefore, a larger second storage space is allocated to the display compensation parameters. When the first pixel ratio is greater than or equal to 10%, it indicates that the display panel has been used for a certain period of time. At this time, the storage space occupied by the lighting duration has increased somewhat, and the second storage space allocated to the compensation parameters needs to be reduced.

[0048] When reducing the second storage space allocated to the compensation parameters, it is also necessary to configure the display compensation parameters of the pixel array on the display panel to reduce the occupied space of the display compensation parameters.

[0049] In some embodiments, before the step of allocating storage space for the display information of each pixel in the display driving chip of the display panel according to the usage time, the method further includes: configuring the display compensation parameters in different display information, which includes:

[0050] Dividing the pixel array of the display panel into blocks, where the first scheme corresponds to the first block scheme for division, the second scheme corresponds to the second block scheme for division, and the size of the pixel array divided by the second block scheme is larger than that of the first block scheme;

[0051] Using the same display compensation parameter for all pixels included in the pixel array within the same block, where the same compensation parameter is the average value of the display compensation parameters of all pixels included in the pixel array within the same block.

[0052] In this embodiment, after dividing the pixel array of the display panel into blocks, each block has N pixels, N is greater than or equal to 1, and the average value of the display compensation parameters of all pixels included in the pixel array within the same block is used as the display compensation parameter for each pixel in this block. This enables only one display compensation parameter to be stored for the pixels within this block, which can greatly reduce the occupied space of the display compensation parameters.

[0053] For example, a pixel array of a block has a total of 16 pixels of 4*4. The display compensation parameters of these 16 pixels are averaged. When storing the display compensation parameters of these 16 pixels, since the display compensation parameters of the 16 pixels are the same, only one display compensation parameter needs to be stored, so that the space occupied by the display compensation parameters of all pixels in this block is 1 / 16 of the original.

[0054] In this embodiment, for the first block scheme, each pixel array is 1*1 and there is a total of one pixel. As Figure 2 shown, the first scheme corresponds to level 1 and the first block scheme. At this time, the storage relationship between the pixel and the display compensation parameter is 1:1, that is, one pixel corresponds to one display compensation parameter. If it is necessary to store the compensation values of 16 pixels, 16 display compensation parameters need to be stored.

[0055] As Figure 2 shown, the calling method of the display compensation value is also one-to-one. That is, when using the display compensation value, if it is necessary to compensate 16 pixels, 16 display compensation parameters need to be called for compensation.

[0056] For the second block scheme, each pixel array has 2*1 and there are a total of 2 pixels. As Figure 2 shown, the second scheme corresponds to level 2 and the second block scheme. At this time, the storage relationship between the pixel and the display compensation value is 2:1, that is, two pixels correspond to one display compensation parameter. If it is necessary to store the display compensation parameters of 16 pixels, 8 display compensation parameters need to be stored, thereby reducing the occupied space of the display compensation parameters.

[0057] As Figure 2 shown, the calling method of the display compensation value is also one-to-one. That is, when using the display compensation value, if it is necessary to compensate 16 pixels, 8 display compensation values need to be called for compensation.

[0058] In other embodiments, the first block scheme and the second block scheme can also be pixel arrays of other sizes. For example, the pixel array included in the first block scheme can also be 1*2, 1*3, 1*4, etc., and the pixel array included in the second block scheme can also be 2*2, 2*3, 2*4, etc. This embodiment does not make specific restrictions.

[0059] In some embodiments, according to the usage time, storage space is allocated for the display information of each pixel in the display driver chip of the display panel, and it further includes:

[0060] Obtain the proportion of the second pixels in each pixel whose usage time is greater than the second threshold and less than the third threshold; if the proportion of the second pixels is less than the preset percentage, use the second scheme to allocate the second storage space; if the proportion of the second pixels is greater than or equal to the preset percentage, use the third scheme to allocate the second storage space; wherein, the second storage space for storing the display compensation parameters in the second scheme is greater than the second storage space for storing the display compensation parameters in the third scheme.

[0061] In this embodiment, the third threshold is a preset value, and the second threshold is less than the third threshold. For example, the value range of the third threshold is 2001 - 3000. This embodiment will take the third threshold as 3000 as an example for illustration.

[0062] In this embodiment, the storage space can be allocated for the lighting duration and the display compensation parameters according to the second pixel ratio. For example, if the preset percentage is 10%, when the first pixel ratio of the pixels with a usage time greater than 2000 and less than 3000 in all pixels is less than 10%, the second storage space is allocated using the second scheme. When the first pixel ratio of the pixels with a usage time greater than 2000 and less than 3000 in all pixels is greater than or equal to 10%, the second storage space is allocated using the third scheme.

[0063] Among them, the second storage space for storing the display compensation parameters in the second scheme is larger than the second storage space for storing the display compensation parameters in the third scheme.

[0064] This is because when the first pixel ratio of the pixels with a usage time greater than 2000 and less than 3000 in all pixels is less than 10%, it means that the display panel has been used for a certain period of time, but not too long. At this time, the storage space occupied by the lighting duration is not large, so a larger second storage space is allocated to the display compensation parameters. When the second pixel ratio is greater than or equal to 10%, it means that the usage time of the display panel has increased, and the usage time of the display panel is relatively long. At this time, the storage space occupied by the lighting duration increases, and the second storage space allocated to the compensation parameters needs to be reduced.

[0065] When reducing the second storage space allocated to the compensation parameters, it is also necessary to configure the display compensation parameters of the pixel array on the display panel to reduce the occupied space of the display compensation parameters.

[0066] In some embodiments, before the step of allocating storage space for the display information of each pixel in the display driver chip of the display panel according to the usage time, the method further includes: configuring the display compensation parameters in different display information, including:

[0067] Dividing the pixel array of the display panel into blocks, where the second scheme corresponds to the second block scheme for dividing the blocks, the third scheme corresponds to the third block scheme for dividing the blocks, and the size of the pixel array divided by the third block scheme is larger than that of the second block scheme;

[0068] Using the same display compensation parameter for all pixels included in the pixel array within the same block, where the same compensation parameter is the average value of the display compensation parameters of all pixels included in the pixel array within the same block.

[0069] In this embodiment, after the pixel array of the display panel is partitioned, each block has N pixels, where N is greater than or equal to 1, and the average value of the display compensation parameters of all the pixels included in the pixel array in the same partition is used as the display compensation parameter for each pixel in this partition. This enables only one display compensation parameter to be stored for the pixels within one partition, which can greatly reduce the occupied space of the display compensation parameters.

[0070] In this embodiment, in the third partitioning scheme, each pixel array has a total of 4 pixels of 2×2, as Figure 2 shown. The third scheme corresponds to 3 levels and corresponds to the third partitioning scheme. At this time, the storage relationship between the pixels and the display compensation values is 4 to 1, that is, four pixels correspond to one display compensation parameter. If it is necessary to store the display compensation parameters of 16 pixels, then 4 display compensation parameters need to be stored, thereby reducing the occupied space of the display compensation parameters.

[0071] As Figure 2 shown, the calling method of the display compensation value is also one-to-one, that is, when using the display compensation value, if it is necessary to compensate 16 pixels, then 8 display compensation values need to be called for compensation.

[0072] In this embodiment, in the second partitioning scheme, each pixel array has a total of 2 pixels of 2×1, and in the third partitioning scheme, each pixel array is 2×2 and has a total of 4 pixels.

[0073] In other embodiments, the second partitioning scheme and the third partitioning scheme can also be pixel arrays of other sizes. For example, the pixel array included in the second partitioning scheme can also be 2×2, 2×3, 2×4, etc., and the pixel array included in the third partitioning scheme can also be 3×1, 3×2, 3×3, etc. This embodiment does not make specific limitations.

[0074] In some embodiments, according to the usage time, storage space is allocated for the display information of each pixel in the display driving chip of the display panel, and it further includes: obtaining the proportion of the third pixels whose usage time is greater than the third threshold among all pixels; if the proportion of the third pixels is greater than or equal to the preset percentage, the fourth scheme is used to allocate the storage space; wherein, the second storage space for storing the display compensation parameters in the third scheme is greater than the second storage space for storing the display compensation parameters in the fourth scheme.

[0075] This embodiment can allocate storage space for the lighting duration and the display compensation parameters according to the proportion of the third pixels. For example, if the preset percentage is 10%, then when the proportion of the pixels with a usage time greater than 3000 among all pixels is greater than 10%, the fourth scheme is used to allocate the second storage space.

[0076] Among them, the second storage space for storing display compensation parameters in the third solution is larger than the second storage space for storing display compensation parameters in the fourth solution.

[0077] This is because when the first pixel ratio of pixels with a usage time greater than 3000 among all pixels is greater than or equal to 10%, it means that the usage time of the display panel is very long. In this case, the storage space occupied by the lighting duration further increases, and it is necessary to further reduce the second storage space allocated to the compensation parameters.

[0078] In the case of reducing the second storage space allocated to the compensation parameters, it is also necessary to configure the display compensation parameters of the pixel array on the display panel to reduce the occupied space of the display compensation parameters.

[0079] In some embodiments, before the step of allocating storage space for the display information of each pixel in the display driver chip of the display panel according to the usage time, the method further includes: configuring the display compensation parameters in different display information, which includes:

[0080] Dividing the pixel array of the display panel into blocks, where the third solution corresponds to the third block division solution, the fourth solution corresponds to the fourth block division solution, and the size of the block division of the pixel array in the fourth block division solution is larger than that in the third block division solution;

[0081] Using the same display compensation parameter for all pixels included in the pixel array within the same block, where the same compensation parameter is the average value of the display compensation parameters of all pixels included in the pixel array within the same block.

[0082] In the case of reducing the second storage space allocated to the compensation parameters, it is also necessary to configure the display compensation parameters of the pixel array on the display panel to reduce the occupied space of the display compensation parameters.

[0083] In some embodiments, before the step of allocating storage space for the display information of each pixel in the display driver chip of the display panel according to the usage time, the method further includes: configuring the display compensation parameters in different display information, which includes:

[0084] Dividing the pixel array of the display panel into blocks, where the second solution corresponds to the second block division solution, the third solution corresponds to the third block division solution, and the size of the block division of the pixel array in the third block division solution is larger than that in the second block division solution;

[0085] Using the same display compensation parameter for all pixels included in the pixel array within the same block, where the same compensation parameter is the average value of the display compensation parameters of all pixels included in the pixel array within the same block.

[0086] In this embodiment, after the pixel array of the display panel is partitioned, each block has N pixels, where N is greater than or equal to 1. And the average value of the display compensation parameters of all the pixels included in the pixel array in the same partition is used as the display compensation parameter for each pixel in this partition. This enables that for the pixels within one partition, only one display compensation parameter needs to be stored, which can greatly reduce the occupied space of the display compensation parameters.

[0087] In this embodiment, in the third partitioning scheme, each pixel array has a total of 4 pixels in a 2*2 arrangement. In the fourth partitioning scheme, each pixel array is 4*4 and has a total of 16 pixels.

[0088] As Figure 2 shown, the fourth scheme corresponds to 4 levels and corresponds to the fourth partitioning scheme. At this time, the storage relationship between the pixels and the display compensation values is 16 to 1, that is, sixteen pixels correspond to one display compensation parameter. If it is necessary to store the display compensation parameters of sixteen pixels, only one display compensation parameter needs to be stored, thereby reducing the occupied space of the display compensation parameters.

[0089] In other embodiments, the third partitioning scheme and the fourth partitioning scheme can also be pixel arrays of other sizes. For example, the pixel array included in the third partitioning scheme can also be 3*1, 3*2, 3*3, etc., and the pixel array included in the fourth partitioning scheme can also be 4*1, 4*2, 4*3, etc. This embodiment does not make specific limitations.

[0090] In some embodiments, according to the usage time, storage space is allocated for the display information of each pixel in the display driver chip of the display panel, and it further includes:

[0091] Obtain the proportion of the fourth pixels whose usage time is less than or equal to the first threshold among all pixels; if the proportion of the fourth pixels is greater than the preset percentage, use the fifth scheme to allocate storage space; wherein, in the fifth scheme, the second storage space for storing the display compensation parameters is larger than the second storage space for storing the display compensation parameters in the second scheme.

[0092] In this embodiment, storage space can be allocated for the lighting duration and the display compensation parameters according to the proportion of the fourth pixels. For example, if the preset percentage is 10%, then when the proportion of the pixels with a usage time greater than 1000 among all pixels is greater than 10%, the fifth scheme is used to allocate the second storage space.

[0093] This is because when the proportion of the first pixels with a usage time less than 1000 among all pixels is less than 10%, it means that the usage of the display panel is very short, and the occupied space of the lighting duration at this time is very small, so the second storage space allocated to the compensation parameters can be increased.

[0094] When reducing the second storage space allocated to the compensation parameters, it is also necessary to configure the display compensation parameters of the pixel array on the display panel to reduce the occupied space of the display compensation parameters.

[0095] In some embodiments, a method for configuring the display compensation parameters in different display information different from the above embodiments is also proposed, which includes:

[0096] Partition the pixel array of the display panel, where the partition in the pixel array includes the first pixel, or the partition in the pixel array includes the first pixel and the second pixel, and the larger the second storage space for storing the display compensation parameters, the fewer the number of second pixels in the partition of the pixel array;

[0097] Obtain the display compensation parameters of the first pixels included in the pixel array within the same partition;

[0098] Within the same partition, obtain the interpolation corresponding to the second pixel adjacent to the first pixel according to the compensation parameters of the first pixel, and the interpolation is used as the display compensation parameter of the second pixel.

[0099] In this embodiment, the first pixel is a used pixel, which means that in the corresponding partition, the display compensation parameter of this pixel is used, and the second pixel is an unused pixel, which means that in the corresponding block, the display compensation parameter of this pixel is not used.

[0100] As Figure 3 shown, the first scheme, the second scheme, the third party, and the fourth scheme are also represented as the first gear, the second gear, the third gear, and the fourth gear respectively. After partitioning the pixel array of the display panel, this embodiment takes a block of 4*4, a total of 16 pixels as an example for illustration. In addition, it should be noted that the partitioning of the pixels can also have other sizes, such as 2*2, 3*3, 4*4, 5*5, etc., which are not limited in this embodiment.

[0101] Among them, in the case of the first gear, it is necessary to store the display compensation parameters of each pixel in the partition, that is, 16 display compensation parameters. When using the first gear, it is necessary to take out and use the 16 display compensation parameters.

[0102] In the case of the second gear, it is necessary to store the display compensation parameters of half of the pixels in the partition, that is, 8 display compensation parameters. For these half of the pixels, in this embodiment, they are taken out according to the standard of alternating rows. For example, for a block of 4*4, a total of 16 pixels, take the four pixels in the first row and the four pixels in the third row for use (that is, Figure 3 groups 1-4, 9-12 under the second gear in ). When using the second gear, it is necessary to take out and use the 8 display compensation parameters, and the display compensation values of the total 8 pixels in the second row and the fourth row that are not taken out are calculated through the interpolation of the four pixels in the first row and the four pixels in the third row.

[0103] In the case of the fourth gear, there is one used pixel and 15 unused pixels. That is, among the 16 pixels in the block, the display compensation parameter of one pixel is used, and the display compensation parameters of 15 pixels are not used. The pixels at the corresponding positions of the unused display compensation parameters are not used, and their display compensation parameters are obtained through compensatory interpolation calculation of the display compensation parameter of the used pixel. In this way, for the 16 pixels in this block, only one display compensation parameter needs to be stored, so that the storage space is 1 / 16 of the original.

[0104] In some embodiments, the display control method further includes: compressing the lighting duration and the display compensation parameter, so that the compressed lighting duration data is stored in the first storage space, and the compressed display compensation parameter data is stored in the second storage space.

[0105] By compressing the lighting duration and the display compensation parameter, the space occupied by the lighting duration and the display compensation parameter can be further reduced.

[0106] In summary, for the first solution, the second solution, the third solution, and the fourth solution, the space occupied by the lighting duration they contain increases in sequence, while the space occupied by the display compensation parameters they contain decreases in sequence, so as to realize the dynamic allocation of the space occupied by the lighting duration and the display compensation parameter, and improve the display effect of the display panel.

[0107] In addition, it can also be integrated Figure 2 or Figure 3 such that the first solution, the second solution, the third solution, and the fourth solution respectively correspond to the first gear, the second gear, the third gear, and the fourth gear. For the storage space occupied by the lighting duration in the four solutions, it can be represented by bit (bit), and the lighting duration of the first solution, the second solution, the third solution, and the fourth solution ranges from the least number of occupied bits to the largest number of bits. For example, the first gear = 8 bits, the second gear = 16 bits, the third gear = 24 bits, the fourth gear = 32 bits. Different gears occupy different spaces, with the first gear being the smallest and the fourth gear being the largest.
