Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Fig. 1 is a schematic diagram illustrating a structure of a terminal 10 according to an exemplary embodiment. As shown in fig. 1, the terminal 10 may include: a processor 11, a screen 12 and n driving chips 13, n being an integer greater than 1.

As shown in fig. 1, the screen 12 includes n display areas 121, and the n display areas 121 and the n driving chips 13 are in one-to-one correspondence. In fig. 1, a schematic illustration is made only by taking the example that the screen 12 includes 2 display areas 121, and each of the 2 display areas 121 has a corresponding driving chip 13.

The first driving chip of the n driving chips 13 is used for driving the first display area of the n display areas 121 to display. The first driving chip may be any one of the n driving chips 13, and similarly, the first display area may be any one of the n display areas 121.

In the disclosed embodiment, the screen 12 may be any display screen that supports display using SPR algorithms, such as an AMOLED (Active Matrix Organic Light Emitting Diode ) screen, a PMOLED (Passive Matrix Organic Light Emitting Diode, passive matrix organic light emitting diode) screen, an LCD (Liquid Crystal Display ) screen, or the like.

The SPR algorithm is a rendering and coloring algorithm of a sub-pixel, and when coloring a sub-pixel, it is necessary to use the surrounding sub-pixels, for example, when calculating the luminance value of a target sub-pixel, it is necessary to use the luminance value of the surrounding sub-pixels, and a correlation algorithm (such as a weighted summation algorithm) is used to calculate the luminance value of the target sub-pixel.

In the embodiment of the present disclosure, the driving chip 13 is a chip for driving the screen 12 to perform light emitting display, for example, the driving chip 13 may be a DDIC (Display Drive Integrated Circuit, display driving integrated circuit).

In the disclosed embodiment, the processor 11 is responsible for executing the processing logic of the terminal 10, and the processor 11 may be referred to as a main chip of the terminal 10, such as an AP (Application Processor ).

In order to realize driving display for each display area 121, the driving chip 13 needs to acquire corresponding display data, for example, the first driving chip needs to acquire the display data of each sub-pixel in the first display area controlled by the driving chip, and then can drive each sub-pixel in the first display area to perform light emitting display based on the display data. The display data corresponding to each driver chip 13 may be provided by the processor 11.

Taking the first driving chip as an example, the processor 11 is configured to send display data corresponding to the first driving chip. In an embodiment of the present disclosure, display data corresponding to a first driving chip includes: display data of each sub-pixel in the first display area, and display data of at least one sub-pixel in other display areas than the first display area.

If only the display data of each sub-pixel in the first display area is sent to the first driving chip, the first driving chip can only use the display data of the sub-pixel in the first display area when performing the SPR calculation on the sub-pixel near the boundary position between the first display area and other display areas, and cannot use the display data of the sub-pixel outside the first display area, so that the display data of the adjacent sub-pixel near the boundary position can be used is missing, and the abnormal display problems such as non-solid color display, obvious cracking sense and the like occur.

In an embodiment of the present disclosure, in order to overcome the above-mentioned problem, the display data received by the first driving chip includes, in addition to the display data of each sub-pixel in the first display area, display data of at least one sub-pixel in other display areas than the first display area. The other display area is a display area adjacent to the first display area, and at least one sub-pixel in the other display area refers to the display data of the sub-pixel which is needed to be used when the SPR algorithm is adopted to calculate the display data of the sub-pixel in the first display area, and the display data of the sub-pixel which is not needed to be used does not need to be sent to the first driving chip, so that the data redundancy is avoided.

The first driving chip is used for carrying out SPR calculation on the target sub-pixel in the first display area according to the display data of the first sub-pixel in the first display area and the display data of the second sub-pixel outside the first display area to obtain the display data of the target sub-pixel. If the display data of the target sub-pixel in the first display area is calculated by adopting the SPR algorithm, the display data of the sub-pixel in the first display area is required to be used, and the display data of the sub-pixel in other display areas except the first display area is required to be used, the first driving chip extracts the display data of the first sub-pixel in the first display area required to be borrowed and the display data of the second sub-pixel outside the first display area required to be borrowed from the received display data, and finally calculates the display data of the target sub-pixel by combining the two data.

By the mode, for the sub-pixels near the boundary position between the first display area and other display areas, the first driving chip can borrow the display data of the sub-pixels outside the first display area when performing SPR calculation on the sub-pixels, so that the problem that the display data of the adjacent sub-pixels near the boundary position can be used by the sub-pixels is missing is solved, the abnormal display problems such as non-solid display, obvious split feeling and the like are avoided, and the display effect of a screen is improved.

Of course, in the above embodiment, the description has been made by taking the SPR calculation of the first display area as an example, when the screen 12 includes a plurality of display areas 121, if any one display area 121 needs to use the display data of the sub-pixels in the other display area when performing the SPR calculation, the display data may be provided to the driving chip 13 corresponding to that display area 121 by the same method.

In addition, the processor 11 can supply display data to the driving chip 13 in the following two ways:

in one possible implementation, the processor 11 sends the display data directly to the driver chip 13. Taking the first driving chip as an example, the processor 11 is configured to obtain complete display data corresponding to the screen 12, where the complete display data includes display data of each sub-pixel in the screen 12; extracting display data corresponding to the first driving chip from the complete display data; and sending the display data corresponding to the first driving chip.

In another possible embodiment, as shown in fig. 2, the processor 11 sends the display data indirectly to the driver chip 13. The processor 11 is configured to obtain complete display data corresponding to the screen 12, where the complete display data includes display data of each sub-pixel in the screen 12; the complete display data is sent to the data processing chip 14. The data processing chip 14 is used for extracting display data corresponding to the first driving chip from the complete display data; and sending the display data corresponding to the first driving chip.

The data processing chip 14 may be an FPGA (Field Programmable Gate Array ) chip, or other form of chip, as embodiments of the present disclosure are not limited in this regard. The number of the data processing chips 14 may be one or a plurality. When the number of the data processing chips 14 is one, the one data processing chip 14 is responsible for extracting the display data corresponding to each of the driving chips 13 of the terminal 10. When the number of the data processing chips 14 is plural, one data processing chip 14 may be used to be responsible for extracting display data corresponding to one or more driving chips 13 of the terminal 10.

It should be noted that the n display areas 121 of the screen 12 may be the same size or different, and the embodiment of the present disclosure is not limited thereto if there are at least two display areas 121 with different sizes.

In the embodiment of the disclosure, the terminal may be any electronic device equipped with a screen, such as a mobile phone, a tablet computer, an electronic book reader, a multimedia playing device, a wearable device, a vehicle-mounted device, a smart home device, and the like.

In summary, according to the technical solution provided in the embodiments of the present disclosure, when the processor sends the display data corresponding to the first driving chip, the display data corresponding to the first driving chip includes, in addition to the display data of each sub-pixel in the first display area, the display data of at least one sub-pixel in the other display areas except the first display area; in this way, for the sub-pixels near the boundary position between the first display area and other display areas, the first driving chip can borrow the display data of the sub-pixels outside the first display area in addition to the display data of the sub-pixels in the first display area when performing the SPR calculation on the sub-pixels, that is, the sub-pixels near the boundary position can borrow the display data of the sub-pixels in the adjacent display area, so that the abnormal display problems such as non-solid display, obvious split feeling and the like can be avoided, and the display effect of the screen is improved.

In addition, compared with the scheme that a data transmission link is established between different driving chips (such as a data line for connecting two driving chips is added), the data transmission link is utilized to realize sharing of display data between the different driving chips, the scheme has larger limitation on selection of the driving chips, the driving chips are required to support data sharing, and the current few driving chips support the data sharing capability between the driving chips.

In the exemplary embodiment, as shown in fig. 3, it is assumed that the screen of the terminal includes a first display area 31 and a second display area 32, the first display area 31 and the second display area 32 are disposed adjacently left and right, a dividing line 33 therebetween is shown, the first display area 31 is left of the dividing line 33, and the second display area 32 is right of the dividing line 33. Correspondingly, the terminal comprises a first driving chip and a second driving chip; the first driving chip is used for driving the first display area 31 to display, and the second driving chip is used for driving the second display area 32 to display.

As shown in fig. 3, the first display area 31 includes a-column subpixels arranged from left to right, the second display area 32 includes b-column subpixels arranged from left to right, and the a-th subpixel in the first display area 31 is adjacent to the 1-th subpixel in the second display area 32, and a and b are integers greater than or equal to 1.

Assuming that the first display area 31 is in a left-right borrowing relationship, that is, for a sub-pixel in the first display area 31, when the first driving chip calculates display data of the sub-pixel by adopting the SPR algorithm, it is necessary to borrow display data of adjacent sub-pixels on the left and right sides of the sub-pixel. Then, the display data corresponding to the first driving chip includes: the display data of the sub-pixels in the a-column in the first display area 31 and the display data of the sub-pixels in the 1 st column to the sub-pixels in the i-column in the second display area 32 are all positive integers less than or equal to b. Thus, for the sub-pixel at the right edge in the first display area 31, the first driving chip can borrow the display data of the adjacent sub-pixel located near the sub-pixel at the right edge in the second display area 32 when calculating the display data of the sub-pixel at the right edge using the SPR algorithm. That is, the display data received by the first driving chip includes the display data of each sub-pixel included in the dashed line box 34 in fig. 3.

Similarly, it is assumed that the second display area 32 is also in a left-right borrowing relationship, that is, for a sub-pixel in the second display area 32, the second driving chip needs to borrow the display data of adjacent sub-pixels on the left and right sides of the sub-pixel when calculating the display data of the sub-pixel by using the SPR algorithm. Then, the display data corresponding to the second driving chip includes: the display data of the b-column sub-pixels in the second display area 32 and the display data of the j-th column sub-pixels to the a-th column sub-pixels in the first display area 31 are all positive integers less than or equal to a. In this way, for the sub-pixel at the left edge in the second display area 32, the second driving chip can borrow the display data of the adjacent sub-pixel located near the sub-pixel at the left edge in the first display area 31 when calculating the display data of the sub-pixel at the left edge using the SPR algorithm. That is, the display data received by the second driving chip includes the display data of each sub-pixel included in the dashed line box 35 in fig. 3.

For example, assuming that the first display area 31 includes 1100 columns of subpixels arranged from left to right and the second display area 32 also includes 1100 columns of subpixels arranged from left to right, the display data corresponding to the first driving chip may include: display data of 1100 columns of sub-pixels in the first display area 31, and display data of 1 st column to x-th column of sub-pixels in the second display area 32, x being a positive integer of 1100 or less; the display data corresponding to the second driving chip may include: the display data of 1100 columns of sub-pixels in the second display area 32, and the display data of 1100-y+1 columns to 1100 columns of sub-pixels in the first display area 31, y being a positive integer of 1100 or less. The values of x and y may be set in combination with the minimum borrowing unit of the SPR algorithm in the practical application scenario, and the values of x and y may be the same or different, which is not limited in the embodiments of the present disclosure. For example, assuming that x and y are the same and are both 4, the display data corresponding to the first driving chip may include: display data of 1100 columns of subpixels in the first display area 31, and display data of 1 st to 4 th columns of subpixels in the second display area 32; the display data corresponding to the second driving chip may include: display data of 1100 columns of sub-pixels in the second display area 32, and display data of 1097 th to 1100 th columns of sub-pixels in the first display area 31.

In an exemplary embodiment, as shown in fig. 4, it is assumed that the screen of the terminal includes a first display area 41 and a third display area 42, the first display area 41 and the third display area 42 being disposed adjacently above and below each other, a dividing line 43 therebetween being shown above the dividing line 43 as the first display area 41, and below the dividing line 43 as the third display area 42. Correspondingly, the terminal comprises a first driving chip and a third driving chip; the first driving chip is used for driving the first display area 41 to display, and the third driving chip is used for driving the third display area 42 to display.

As shown in fig. 4, the first display area 41 includes c rows of subpixels arranged from top to bottom, the third display area 42 includes d rows of subpixels arranged from top to bottom, and the c-th row of subpixels in the first display area 41 is adjacent to the 1 st row of subpixels in the third display area 42, and c and d are integers greater than or equal to 1.

Assuming that the first display area 41 is in a top-bottom borrowing relationship, that is, for a sub-pixel in the first display area 41, when the first driving chip calculates the display data of the sub-pixel by adopting the SPR algorithm, the display data of adjacent sub-pixels on the top and bottom sides of the sub-pixel need to be borrowed. Then, the display data corresponding to the first driving chip includes: the display data of the c-line sub-pixels in the first display area 41 and the display data of the 1 st-line sub-pixels to the p-line sub-pixels in the third display area 42 are described above, and p is a positive integer less than or equal to d. In this way, for the sub-pixel at the lower edge in the first display area 41, the first driving chip can borrow the display data of the adjacent sub-pixel located near the sub-pixel at the lower edge in the third display area 42 when calculating the display data of the sub-pixel at the lower edge using the SPR algorithm. That is, the display data received by the first driving chip includes the display data of each sub-pixel included in the dashed line box 44 in fig. 4.

Similarly, it is assumed that the third display area 42 is also in a top-bottom borrowing relationship, that is, for the sub-pixel in the third display area 42, the third driving chip needs to borrow the display data of the adjacent sub-pixels on the top and bottom sides of the sub-pixel when calculating the display data of the sub-pixel by using the SPR algorithm. Then, the display data corresponding to the third driving chip includes: the display data of the d-row sub-pixels in the third display area 42 and the display data of the q-th row sub-pixels to the c-th row sub-pixels in the first display area 41 are described above, and q is a positive integer less than or equal to c. Thus, for the sub-pixel at the upper edge in the third display area 42, the third driving chip can borrow the display data of the adjacent sub-pixel located near the sub-pixel at the upper edge in the first display area 41 when calculating the display data of the sub-pixel at the upper edge using the SPR algorithm. That is, the display data received by the third driving chip includes the display data of each sub-pixel included in the dashed line box 45 in fig. 4.

For example, assuming that the first display area 41 includes 1000 rows of subpixels arranged from top to bottom and the third display area 42 includes 1200 rows of subpixels arranged from top to bottom, the display data corresponding to the first driving chip may include: display data of 1000 lines of sub-pixels in the first display area 41, and display data of 1 st to v th lines of sub-pixels in the third display area 42, v being a positive integer of 1000 or less; the display data corresponding to the third driving chip may include: display data of 1200 rows of sub-pixels in the third display area 42, and display data of 1000-w+1 columns to 1000 rows of sub-pixels in the first display area 41, w being a positive integer of 1000 or less. The values of v and w may be set in combination with the minimum borrowing unit of the SPR algorithm in the actual application scenario, and the values of v and w may be the same or different, which is not limited in the embodiments of the present disclosure. For example, assuming that v and w are the same and are both 6, the display data corresponding to the first driving chip may include: display data of 1000 lines of subpixels in the first display area 41, and display data of 1 st to 6 th lines of subpixels in the third display area 42; the display data corresponding to the third driving chip may include: display data of 1200 lines of subpixels in the third display area 42, and display data of 995 th to 1000 th lines of subpixels in the first display area 41.

Referring to fig. 5 in combination, it is assumed that the screen of the terminal includes a first display area 51 and a second display area 52, the first display area 51 and the second display area 52 being adjacently disposed left and right, a dividing line 53 therebetween being shown, the dividing line 53 being to the left of the first display area 51 and the dividing line 53 being to the right of the second display area 52. Correspondingly, the terminal comprises a first driving chip and a second driving chip; the first driving chip is used for driving the first display area 51 to display, and the second driving chip is used for driving the second display area 52 to display. Assuming that the first display area 51 and the second display area 52 are both in a left-right borrowing relationship, the minimum borrowing unit is 6 sub-pixels, that is, two columns of sub-pixels in the dashed box 54 need to borrow two columns of sub-pixels on the left side and two columns of sub-pixels on the right side, and two columns of sub-pixels in the dashed box 55 need to borrow two columns of sub-pixels on the left side and two columns of sub-pixels on the right side. If the display data sent to the first driving chip includes only the display data of each sub-pixel in the first display area 51, then for the two columns of sub-pixels in the dashed box 54, when calculating their display data using the SPR algorithm, the two columns of sub-pixels on the right side thereof cannot be used; similarly, if the display data sent to the second driving chip includes only the display data of each sub-pixel in the second display area 52, for the two columns of sub-pixels in the dashed line box 55, when the SPR algorithm is adopted to calculate the display data, the two columns of sub-pixels on the left side cannot be used, which results in abnormal display near the dividing line 53.

In fig. 3 and 4, the SPR algorithm is described as a side-to-side borrowing relationship or a side-to-side borrowing relationship, and if the SPR algorithm is to use the side-to-side borrowing relationship and the side-to-side borrowing relationship at the same time, the above example may be combined, and when display data is transmitted to a driving chip corresponding to a certain display area, display data including sub-pixels in other display areas adjacent to the display area in the side-to-side direction and display data including sub-pixels in other display areas adjacent to the display area in the side-to-side direction may be included.

In summary, in the technical solution provided in the embodiments of the present application, a left-right borrowing relationship or an up-down borrowing relationship is adopted for the SPR algorithm, so that a corresponding solution is provided, whether the left-right borrowing relationship or the up-down borrowing relationship is adopted, or both the left-right borrowing relationship and the up-down borrowing relationship are adopted, so that the abnormal display problem near the dividing line can be effectively eliminated, and the display effect of the screen is improved.

Fig. 6 is a flowchart illustrating a display data transmission method according to an exemplary embodiment, which is applicable to the processor 11 of the terminal 10 described in the above embodiments. The method may comprise the steps of:
