All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one relationship describing the association of the associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

The embodiment of the invention provides a driving method of a display panel, which can be applied to the display panel shown in fig. 1.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, where the display panel includes a display area 1, and the display area 1 includes a main display area 2 and an optical component setting area 3, where the optical component setting area 3 is used for setting optical components such as a camera, and the main display area 2 may be other conventional display areas except for the optical component setting area 3 in the display area 1. The display panel further comprises a first sub-pixel 4 located in the main display area 2 and a second sub-pixel 5 located in the optical component arrangement area 3, wherein the pixel density of the second sub-pixel 5 in the optical component arrangement area 3 is smaller than or equal to the pixel density of the first sub-pixel 4 in the main display area 2 in order to increase the light transmittance of the optical component arrangement area 3. The pixel density according to the present invention is understood to be the density of the light emitting element.

Based on the above structure, the driving method provided by the embodiment of the invention includes: the second sub-pixels 5 alternately display sub-pixel information corresponding to N low resolution pictures, which constitute the first high resolution picture.

As shown in fig. 2, fig. 2 is a schematic diagram of a low resolution screen provided by an embodiment of the present invention, in which a screen desired to be displayed by the optical component setting area 3 in an ideal state is defined as a preset display screen 6, and the resolution of the preset display screen 6 is the same as the resolution of a screen displayed by the same area as the optical component setting area 3 in the main display area 2. Taking the example that the pixel density of the second sub-pixel 5 in the optical component setting area 3 is smaller than the pixel density of the first sub-pixel 4 in the main display area 2, the preset display screen 6 can be understood as a screen which can be displayed when the optical component setting area 3 adopts the same pixel density as the main display area 2 under ideal conditions.

The N low resolution frames 7 are N preset frame portions split from the preset display frame 6, and take the pixel density of the second sub-pixel 5 in the optical component setting area 3 as an example, which is smaller than the pixel density of the first sub-pixel 4 in the main display area 2, where each low resolution frame 7 corresponds to a frame to be displayed in a state of ideal PPI at different positions in the optical component setting area 3. The sub-pixel information corresponding to the low resolution picture 7 is preset light emitting brightness information of a preset light emitting point of the low resolution picture 7, the resolution of each low resolution picture 7 is the same as the actual resolution of the picture displayed by the optical component setting area 3, the resolution of the first high resolution picture is higher than the resolution of the low resolution picture 7, and the resolution of the first high resolution picture is the same as the resolution of the preset display picture 6.

In the embodiment of the present invention, as shown in fig. 3 in conjunction with fig. 2, fig. 3 is a schematic diagram of displaying sub-pixel information in N low resolution frames in turn in the second sub-pixel corresponding to fig. 2, when the display panel displays a frame of to-be-displayed frame, a frame time may be split into N sub-frames, and for the second sub-pixel 5 in the optical component setting area 3, first, in the 1 st sub-frame, the part of the second sub-pixel 5 is driven to display sub-pixel information corresponding to the 1 st low resolution frame 7, so that the optical component setting area 3 displays the 1 st low resolution frame, then, in the 2 nd sub-frame, the part of the second sub-pixel 5 is driven to display sub-pixel information corresponding to the 2 nd low resolution frame 7, so that the optical component setting area 3 displays the 2 nd low resolution frame 7, and so on until in the N sub-frame, the part of the second sub-pixel 5 is driven to display sub-pixel information corresponding to the N low resolution frame 7.

The display of the low resolution screen 7 by the optical component installation area 3 means that the content of the screen displayed by the optical component installation area 3 is the same as the content of the low resolution screen 7, the position of the screen displayed by the optical component installation area 3 is determined by the position of the second sub-pixel 5, and the position of the screen displayed by the optical component installation area 3 may be the same as or different from the position of the low resolution screen 7 in the optical component installation area 3.

When the optical component setting area 3 alternately displays the plurality of low resolution pictures 7 at high frequency based on the persistence of vision characteristic of human eyes, human eyes can perceive a first high resolution picture mixed by the plurality of low resolution pictures 7, which approaches a preset display picture 6 which the optical component setting area 3 is expected to present in an ideal state. Therefore, by adopting the driving method provided by the embodiment of the invention, the second sub-pixel 5 with lower pixel density in the optical component setting area 3 can be utilized to simulate and display a picture with higher resolution, so that the display effect of the optical component setting area 3 and the display effect of the main display area 2 tend to be consistent, and the display performance is improved. In addition, the embodiment of the invention can ensure higher light transmittance of the optical component setting area 3 without adjusting the pixel density of the second sub-pixel 5 in the optical component setting area 3.

It should be noted that the refresh frequency of the second sub-pixel 5 in the optical component setting area 3 may be N times the refresh frequency of the first sub-pixel 4 in the main display area 2, and the refresh frequency may be understood as the frequency of the data signal update. For example, the refresh frequency of the first sub-pixel 4 in the main display area 2 is 60Hz, that is, the data signal received by the first sub-pixel 4 is updated 60 times in one frame time, and when n=2, the refresh frequency of the second sub-pixel 5 in the optical component setting area 3 is 120Hz, that is, the data signal received by the second sub-pixel 5 is updated 120 times in one frame time. Alternatively, the refresh frequency of the second sub-pixel 5 in the optical member setting area 3 may be the same as the refresh frequency of the first sub-pixel 4 in the main display area 2. For example, the refresh frequency of the first sub-pixel 4 in the main display area 2 and the second sub-pixel 5 in the optical component setting area 3 is 120Hz, but the data signal corresponding to the optical component setting area 3 is updated every frame, and the data signal corresponding to the main display area 2 is updated every N frames.

In an alternative embodiment, 2.ltoreq.N.ltoreq.4.

So set up, the required split of the preset display screen 6 is not excessive in quantity of the low-resolution pictures 7, when the multiple low-resolution pictures 7 that the second sub-pixel 5 displays in turn are mixed into the first high-resolution picture, the synthesis effect of the first high-resolution picture is better, and then make the picture perceived by human eyes more approximate to the preset display screen 6 that the optical component setting area 3 hopes to present under ideal condition.

In addition, when the pixel density of the second sub-pixel 5 in the optical component setting area 3 is smaller than the pixel density of the first sub-pixel 4 in the main display area 2, the preset display screen 6 is split into N preset screen portions, that is, the pixel density of the second sub-pixel 5 in the optical component setting area 3 is one-half of the pixel density of the first sub-pixel 4 in the main display area 2, and by setting the value of N in the range of 2 to 4, the pixel density in the optical component setting area 3 is at most one-half of the pixel density in the main display area 2, so that the optical component setting area 3 can be ensured to have better light transmission performance, and at the same time, the pixel density in the optical component setting area 3 is at least one-fourth of the pixel density in the main display area 2, the number of the second sub-pixels 5 in the optical component setting area 3 is not too small, and the composite effect of the first high resolution screen is improved.

In an alternative embodiment, referring to fig. 2 and 3, the optical member arrangement region 3 includes a plurality of first regions 8, the first regions 8 including light emitting regions 9 and light transmitting regions 10 arranged along a first direction, and the second sub-pixels 5 are located at the light emitting regions 9. Each low resolution picture 7 comprises a plurality of areas 11 to be displayed, and the second sub-pixels 5 in the light emitting area 9 alternately display the sub-pixel information of the areas 11 to be displayed in the N low resolution pictures 7.

Specifically, in the 1 st sub-frame, the second sub-pixels 5 in the plurality of light emitting areas 9 display the sub-pixel information of the plurality of areas to be displayed 11 in the 1 st low resolution picture 7, respectively, so that the optical component setting area 3 displays the 1 st low resolution picture 7, then, in the 2 nd sub-frame, the second sub-pixels 5 in the plurality of light emitting areas 9 display the sub-pixel information of the plurality of areas to be displayed 11 in the 2 nd low resolution picture 7, respectively, so that the optical component setting area 3 displays the 2 nd low resolution picture 7, … …, respectively, and so on, so that the optical component setting area 3 displays the complete low resolution picture 7, respectively, in each sub-frame.

In an alternative embodiment, as shown in fig. 4A and fig. 4B, fig. 4A is a schematic diagram of a low resolution screen provided by the embodiment of the present invention, fig. 4B is a schematic diagram of a second sub-pixel corresponding to fig. 4A displaying sub-pixel information in N low resolution screens in turn, the low resolution screen 7 includes a first low resolution screen 71, the first low resolution screen 71 includes a plurality of first areas to be displayed 111, and the first areas to be displayed 111 are disposed corresponding to the light emitting areas 9. For the corresponding light emitting region 9 and first region to be displayed 111, the light emitting region 9 includes the second sub-pixels 5 arranged according to the first manner, and the sub-pixel information in the first region to be displayed 111 is the sub-pixel information arranged according to the first manner.

In the above arrangement, the first to-be-displayed area 111 is arranged corresponding to the light-emitting area 9, and when the second sub-pixel 5 in the light-emitting area 9 displays the sub-pixel information in the corresponding first to-be-displayed area 111, the position of the picture presented by the light-emitting area 9 coincides with the position of the first to-be-displayed area 111, so that the position of the picture presented by the whole optical component arrangement area 3 coincides with the position of the first low resolution picture 71. When the first high-resolution screen is formed by using the first low-resolution screen 71, the deviation between the formed first high-resolution screen and the preset display screen 6 can be reduced, and the screen perceived by human eyes is more similar to the screen desired to be presented in the ideal state by the optical component setting area 3.

Further, referring to fig. 4A and 4B, the second sub-pixel 5 in the light emitting region 9 includes a red sub-pixel 51, a first green sub-pixel 52, a blue sub-pixel 53, and a second green sub-pixel 54. The sub-pixel information in the first region to be displayed 111 includes sub-pixel information of a first red preset light emitting point 510, a first green preset light emitting point 520, a first blue preset light emitting point 530, and a second green preset light emitting point 540. When the second sub-pixel 5 in the light emitting area 9 displays the sub-pixel information in the first area to be displayed 111, the light emitting luminance of the red sub-pixel 51 is the same as the preset luminance of the first red preset light emitting point 510, the preset luminance of the first green sub-pixel 52 is the same as the preset luminance of the first green preset light emitting point 520, the light emitting luminance of the blue sub-pixel 53 is the same as the preset luminance of the first blue preset light emitting point 530, and the light emitting luminance of the second green sub-pixel 54 is the same as the preset luminance of the second green preset light emitting point 540.

In connection with the above analysis, in the optical component setting area 3, the red sub-pixel 51, the first green sub-pixel 52, the blue sub-pixel 53, and the second green sub-pixel 54 are respectively at the same positions as the first red preset light emitting point 510, the first green preset light emitting point 520, the first blue preset light emitting point 530, and the second green preset light emitting point 540, and therefore, when the second sub-pixel 5 displays the sub-pixel information of the first low resolution screen 71, the second sub-pixel 5 of each color may directly display the preset light emitting brightness of the preset light emitting point of the same color at the position where it is located, and at this time, the screen displayed by the optical component setting area 3 has no deviation from the first low resolution screen 71.

In the drawings of the embodiments of the present invention, li illustrated in the preset display screen 6 and the low resolution screen 7 represents preset luminance of a preset light emitting point, and Li illustrated in the second sub-pixel 5 represents light emitting luminance of the second sub-pixel 5 when the sub-pixel information of the low resolution screen 7 is displayed, and Li is used when the light emitting luminance is the same as the preset luminance.

In an alternative embodiment, referring to fig. 4A and 4B, the low resolution screen 7 includes at least one second low resolution screen 72, the second low resolution screen 72 includes a plurality of second areas to be displayed 112, the second areas to be displayed 112 are disposed corresponding to the light-transmitting areas 10, and sub-pixel information in the second areas to be displayed 112 is sub-pixel information arranged in a second manner.

In the above arrangement, the position of the second region to be displayed 112 in the second low resolution screen 72 corresponds to the position of the light transmitting region 10, and therefore, when the sub-pixel information in the second low resolution screen 72 is displayed, the second sub-pixel 2 in the light emitting region 9 coincides with the position of the second low resolution screen 72 after the position of the screen presented by the optical component setting region 3 is shifted.

Further, referring to fig. 4A and 4B, the second sub-pixel 5 in the light emitting region 9 includes a red sub-pixel 51, a first green sub-pixel 52, a blue sub-pixel 53, and a second green sub-pixel 54. The sub-pixel information in the second to-be-displayed area 112 includes sub-pixel information of a second red preset light emitting point 511, a third green preset light emitting point 521, a second blue preset light emitting point 531, and a fourth green preset light emitting point 541.

When the second sub-pixel 5 in the light emitting area 9 displays the sub-pixel information in the second area to be displayed 112, the light emitting luminance of the red sub-pixel 51 is the same as the preset luminance of the second preset light emitting point 511, the preset luminance of the first green sub-pixel 52 is the same as the preset luminance of the third preset light emitting point 521, the light emitting luminance of the blue sub-pixel 53 is the same as the preset luminance of the second preset light emitting point 531, and the light emitting luminance of the second green sub-pixel 54 is the same as the preset luminance of the fourth preset light emitting point 541.

In combination with the above analysis, in the optical component setting area 3, the position after the translation of the light emitting area 9 coincides with the position of the second area to be displayed 112, when the second sub-pixel 5 in the light emitting area 9 displays the sub-pixel information in the second area to be displayed 112, by causing the red sub-pixel 51, the first green sub-pixel 52, the blue sub-pixel 53, and the second green sub-pixel 54 to display the preset luminances of the second red preset light emitting point 511, the third green preset light emitting point 521, the second blue preset light emitting point 531, and the fourth green preset light emitting point 541, respectively, the light emitting luminances of the second sub-pixel 5 of each color are the same as the light emitting luminances of the preset light emitting points of the same color closest to the position thereof, and at this time, the deviation between the screen displayed by the optical component setting area 3 and the second low resolution screen 72 is small or even no deviation.

In one possible embodiment, referring to fig. 4A and 4B, and fig. 6A and 6B, the light emitting region 9 includes a first type light emitting region 91, and the first type light emitting region 91 includes a red sub-pixel 51, a first green sub-pixel 52, a blue sub-pixel 53, and a second green sub-pixel 54, which are sequentially arranged; at least a portion of the second low resolution frame 72 includes a first type second to-be-displayed area 1121, where the first type second to-be-displayed area 1121 is disposed corresponding to the light-transmitting area 10 in the first area 8 where the first type light-emitting area 91 is located, and sub-pixel information of the first type second to-be-displayed area 1121 is sub-pixel information of the second red preset light-emitting point 511, the third green preset light-emitting point 521, the second blue preset light-emitting point 531 and the fourth green preset light-emitting point 541 that are sequentially arranged.

And/or the light emitting region 9 includes a second type light emitting region 92, the second type light emitting region 92 including a blue sub-pixel 53, a first green sub-pixel 52, a red sub-pixel 51, and a second green sub-pixel 54 arranged in this order; at least a portion of the second low resolution frame 72 includes a second type second to-be-displayed area 1122, where the second type second to-be-displayed area 1122 is disposed corresponding to the light-transmitting area 10 in the first area 8 where the second type light-emitting area 92 is located, and sub-pixel information of the second type second to-be-displayed area 1122 is sub-pixel information of a second blue preset light-emitting point 531, a third green preset light-emitting point 521, a second red preset light-emitting point 511, and a fourth green preset light-emitting point 541 that are sequentially arranged.

So configured, the positions of the red sub-pixel 51, the first green sub-pixel 52, the blue sub-pixel 53 and the second green sub-pixel 54 in the first light emitting region 91 after translation are respectively overlapped with the positions of the second red preset light emitting point 511, the third green preset light emitting point 521, the second blue preset light emitting point 531 and the fourth green preset light emitting point 541 in the first type second to-be-displayed region 1121, and when the red sub-pixel 51, the first green sub-pixel 52, the blue sub-pixel 53 and the second green sub-pixel 54 respectively display the preset luminances of the second red preset light emitting point 511, the third green preset light emitting point 521, the second blue preset light emitting point 531 and the fourth green preset light emitting point 541, the picture presented by the first light emitting region 91 is not deviated from the picture of the first type second to-be-displayed region 1121, so that the picture presented by the whole optical component setting region 3 is not deviated from the second low resolution picture 71 including the first type second to-be-displayed region 1121, and the display precision is higher. The second light emitting region 92 is similar to the second type of second to-be-displayed region 1122, and will not be described herein.

In one possible embodiment, referring to fig. 8A and 8B, the light emitting region 9 includes a first type light emitting region 91, and the first type light emitting region 91 includes a red sub-pixel 51, a first green sub-pixel 52, a blue sub-pixel 53, and a second green sub-pixel 54, which are sequentially arranged; at least a portion of the second low resolution screen 72 includes a third type of second to-be-displayed area 1123, where the third type of second to-be-displayed area 1123 is set corresponding to the light-transmitting area 10 in the first area 8 where the first type of light-emitting area 91 is located, and sub-pixel information of the third type of second to-be-displayed area 1123 is sub-pixel information of a second blue preset light-emitting point 531, a third green preset light-emitting point 521, a second red preset light-emitting point 511, and a fourth green preset light-emitting point 541, which are sequentially arranged.

And/or the light emitting region 9 includes a second type light emitting region 92, the second type light emitting region 92 including a blue sub-pixel 53, a first green sub-pixel 52, a red sub-pixel 51, and a second green sub-pixel 54 arranged in this order; at least a portion of the second low resolution frame 72 includes a fourth type of second to-be-displayed area 1124, where the fourth type of second to-be-displayed area 1124 is set corresponding to the light-transmitting area 10 in the first area 8 where the second type of light-emitting area 92 is located, and sub-pixel information of the fourth type of second to-be-displayed area 1124 is sub-pixel information of the second red preset light-emitting point 511, the third green preset light-emitting point 521, the second blue preset light-emitting point 531 and the fourth green preset light-emitting point 541 that are sequentially arranged.

When the second sub-pixel 5 in the first light emitting area 91 displays the sub-pixel information in the third type second area 1123 to be displayed, the deviation between the frame presented by the first light emitting area 91 and the frame presented by the third type second area 1123 to be displayed can be reduced by making the red sub-pixel 51 and the blue sub-pixel 53 display the preset luminance of the second red preset light emitting point 511 and the second blue preset light emitting point 531, respectively, that is, making the red sub-pixel 51 and the blue sub-pixel 53 display the preset luminance of the same color preset light emitting point closest to the position after the translation. The second light emitting region 92 is similar to the fourth type of second to-be-displayed region 1124, and will not be described herein.

Based on the same inventive concept, an embodiment of the present invention further provides a display device, as shown in fig. 13, and fig. 13 is a schematic structural diagram of the display device provided in the embodiment of the present invention, where the display device includes the display panel 100. The specific structure of the display panel 100 is described in detail in the above embodiments, and will not be described here again. Of course, the display device shown in fig. 13 is only a schematic illustration, and the display device may be any electronic apparatus having a display function, such as a mobile phone, a tablet computer, a notebook computer, an electronic book, or a television.

In an alternative implementation, as shown in fig. 14, fig. 14 is a schematic diagram of another structure of a display device provided by an embodiment of the present invention, where the display device further includes a first driving circuit 101 and a second driving circuit 102, where the first driving circuit 101 is electrically connected to a first sub-pixel 4 (not shown in the figure) in the main display area 2, and is configured to transmit a driving signal to the first sub-pixel 4; the second driving circuit 102 is electrically connected (not shown in the drawing) to the second sub-pixel 5 in the optical component setting area 3 for transmitting a driving signal to the second sub-pixel 5.

In the embodiment of the present invention, the second sub-pixels 5 in the optical component setting area 3 may be individually driven by using one second driving circuit 102, and the scan signal and the data signal are individually supplied thereto, so that the refresh frequency of the second sub-pixels 5 is higher than the refresh frequency of the first sub-pixels 4, and the second sub-pixels 5 alternately display the low resolution picture 7 at a high frequency.

The area of the optical component mounting region 3 is small compared to the main display region 2, and therefore the number of lines of the second sub-pixels 5 in the optical component mounting region 3 is small. For example, when the first sub-pixels 4 in the main display area 2 are arranged in 2000 or more rows, the second sub-pixels 5 in the optical component mounting area 3 are generally arranged in only about 200 rows, and therefore, the second driving circuit 102 is required to simply drive the optical component mounting area 3 alone, with high feasibility.

Further, referring to fig. 14, the display panel further includes a non-display area 30 surrounding the display area 1, and the second driving circuit 102 is located on a side of the non-display area 30 near the optical component setting area 3, so that the distance between the second driving circuit 102 and the optical component setting area 3 is closer, the length of the lead between the second driving circuit 102 and the second sub-pixel 5 is reduced, and the space occupied by the lead in the non-display area 30 is further reduced, which is more beneficial to realizing the narrow frame design of the display panel.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the invention.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
