It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
It will be understood that when a layer, region or layer is referred to as being "on" or "over" another layer, region or layer in describing the structure of the component, it can be directly on the other layer, region or layer or intervening layers or regions may also be present. Also, if the component is turned over, one layer or region may be "under" or "beneath" another layer or region.
On electronic devices such as mobile phones and tablet computers, it is necessary to integrate a photosensitive component such as a front camera, an infrared light sensor, a proximity light sensor, and the like on the side where the display panel is provided. In some embodiments, a transparent display area may be disposed on the electronic device, and the photosensitive component is disposed on the back of the transparent display area, so that full-screen display of the electronic device is achieved under the condition that the photosensitive component is ensured to work normally.
The transparent display area is usually a rectangular area, and the transparent display area is directly set to be in the shape of an area with a curved edge, such as a circular area or an elliptical area, which is difficult in process. When displaying, the edges of the rectangular light-transmitting display area have abrupt corner feeling, which affects the user experience.
In order to solve the above problems, embodiments of a display control method, a display control apparatus, and a display apparatus according to the present invention are described below with reference to the accompanying drawings.
In a first aspect, an embodiment of the present invention provides a display control method for a display panel, where the display panel may be an Organic Light Emitting Diode (OLED) display panel or a liquid crystal display panel.
Fig. 1 is a flowchart illustrating a display control method according to an embodiment of the present invention.
Fig. 2 illustrates a schematic top view of a display panel provided according to an embodiment of the present invention.
As shown in fig. 2, the display panel 100 has a first display area AA1 and a second display area AA2, and the light transmittance of the first display area AA1 is greater than that of the second display area AA 2.
Herein, the light transmittance of the first display area AA1 may be 15% or more. To ensure that the light transmittance of the first display area AA1 is greater than 15%, even greater than 40%, or even higher, the light transmittance of at least part of the functional film layer of the display panel in this embodiment may be greater than 80%, or even greater than 90%.
The light transmittance of the first display area AA1 of the display panel 100 is greater than that of the second display area AA2, so that photosensitive components can be integrated on the back of the display panel 100 in the first display area AA1, for example, the photosensitive components of a camera can be integrated under a screen, the first display area AA1 can display a picture, the display area of the display panel 100 is increased, and the comprehensive screen design of the display device is realized.
The first display area AA1 is rectangular in shape. The light transmittance of the first display area AA1 is usually increased by decreasing the pixel density (Pixels Per inc, PPI) of the first display area AA1, but the display effect is deteriorated with the decrease of the pixel density, so the size of the first display area AA1 can be set to be smaller, and the size of the first display area AA1 can only cover the photosensitive surface of the photosensitive element. That is, the area of the second display area AA2 is much larger than that of the first display area AA 1.
As shown in fig. 1, a display control method provided in an embodiment of the present invention may include the following steps:
According to the display control method provided by the embodiment of the invention, the area of the second display area is usually far larger than that of the first display area, and other areas except the selected area in the second display area are displayed in a sub-pixel rendering mode, so that the display panel has higher resolution as a whole. The first display area and the selected area are displayed in a second display mode different from the sub-pixel rendering mode, namely, the sub-pixel rendering function of the first display area and the selected area is closed, so that the brightness of each sub-pixel in the first display area and the selected area can be independently controlled, and further the brightness of each sub-pixel in the first display area and the selected area can be accurately controlled. In addition, the first display area is usually a rectangular area, the second light-emitting combination unit formed by the second target sub-pixels selected in the application is the same as the first light-emitting combination unit formed by the first target sub-pixels in the first display area, that is, the application simulates the first sub-area in the selected area into a virtual first display area, which is equivalent to enlarging the area of the actual first display area, that is, the boundary of the first sub-area is the display boundary of the first display area, the boundary of the first sub-area is a preset curve, and the brightness of each sub-pixel of the first display area and the first sub-area can be controlled independently, so that the actual boundary of the first display area has no abrupt corner feeling any more, and the user experience is improved.
As shown in fig. 2, the first display area AA1 may be located at an upper edge of the display panel 100. The selected area S selected in step 110 and the first display area AA1 still form a rectangular area as a whole. In general, the rectangular display area may be controlled to be displayed in a sub-pixel rendering manner, so that the selected area S and the first display area AA1 form a rectangular area as a whole, which is more convenient for the step 140.
In step 120, as shown in fig. 2, the selected area S is divided into a first sub-area S1 and a second sub-area S2. The first sub-region S1 is located between the first display region AA1 and the second sub-region S2. The boundary between the first sub-region S1 and the second sub-region S2 is a predetermined curve, and the specific shape of the curve can be set according to actual requirements. For example, the first sub-region S1 and the first display region AA1 may be formed in a droplet-like shape as a whole, or the first sub-region S1 and the first display region AA1 may be formed in a circular shape, an oval shape, or the like as a whole.
In the present application, the selected area S belongs to a part of the second display area AA2, and the structure of the display panel is not changed in the present application. I.e. the second display area AA2 comprises a selected area S and a non-selected area TS. The non-selected area TS is an area other than the selected area S in the second display area AA 2.
As shown in fig. 3, the selected area S1 is the same as the non-selected area TS in pixel arrangement and pixel density. It should be understood that the structure of the second display area AA2 is not changed, and only the selected area S1 and the unselected area TS are controlled to be displayed in different display manners.
The first display area AA1 includes a plurality of first target subpixels, and the second display area AA2 includes a plurality of second subpixels. Illustratively, first display area AA1 includes a plurality of first repeat units 10 arranged in an array, and second display area AA2 includes a plurality of second repeat units 20 arranged in an array. Each of the first repeating units 10 includes two columns of the first target sub-pixels distributed in the first direction X, each of the columns of the first target sub-pixels includes three first target sub-pixels of three colors arranged in the second direction Y, and the color arrangement order of the two columns of the first target sub-pixels is different. Illustratively, in the first repeating unit 10, the color arrangement order of one column of the first target sub-pixels is the first target sub-pixel 10b of the second color, the first target sub-pixel 10c of the third color and the first target sub-pixel 10a of the first color, and the color arrangement order of the other column of the first target sub-pixels is the first target sub-pixel 10a of the first color, the first target sub-pixel 10b of the second color and the first target sub-pixel 10c of the third color.
Each of the second repeating units 20 includes two columns of second sub-pixels distributed in the first direction X, each of the columns of second sub-pixels includes three second sub-pixels of three colors arranged in the second direction Y, and the color arrangement order of the two columns of second sub-pixels is different. In the second repeating unit 20, the color arrangement order of one column of the second sub-pixels is the second sub-pixel 20b of the second color, the second sub-pixel 20a of the first color and the second sub-pixel 20c of the third color, and the color arrangement order of the other column of the second sub-pixels is the second sub-pixel 20c of the third color, the second sub-pixel 20b of the second color and the second sub-pixel 20a of the first color.
Illustratively, the first color is red, the second color is green, and the third color is blue.
Wherein the first direction X intersects the second direction Y. For example, the first direction X may be perpendicular to the second direction Y.
In order to improve the light transmittance of the first display area AA1, the pixel density of the first display area AA1 may be reduced. Illustratively, as shown in fig. 3, the pixel density of the first display area AA1 may be reduced by increasing the distance between adjacent first target sub-pixels in the first repeating unit 10. For better understanding, the first display area AA1 is illustrated in fig. 3 as including a virtual sub-pixel 10 s. Illustratively, the virtual sub-pixel 10s may not be a real light-emitting sub-pixel, which merely indicates that one first target sub-pixel can be disposed in the position, but the position is not disposed with a sub-pixel structure, so that the distance between adjacent first target sub-pixels is increased, i.e. the first display area AA1 includes only the first target sub-pixel. Illustratively, as shown in fig. 3, one first repeating unit 10 occupies the same space as four second repeating units 20 of 2 rows and 2 columns. For example, the first target sub-pixel of the first display area AA1 and the second sub-pixel of the second display area AA2 may be formed by using the same mask, which not only increases the light transmittance of the first display area AA1 but also reduces the process. For another example, the virtual sub-pixel 10s may be a non-target sub-pixel of the first display area AA1, that is, the virtual sub-pixel 10s may be a real light-emitting sub-pixel, and the virtual sub-pixel 10s may be controlled to be always in a non-light-emitting state, so as to increase the light transmittance of the first display area AA 1.
In step 120, as shown in fig. 3 and 4, when the first sub-region S1 and the second sub-region S2 are divided, some of the second sub-pixels are divided into two parts by the boundary between the two sub-regions, and the sub-region to which the second sub-pixels finally belong can be determined according to the areas of the second sub-pixels in the two sub-regions. For example, a second sub-pixel is divided into a first portion and a second portion by a boundary, and the area of the first portion in the first sub-region S1 is larger than the area of the second portion in the second sub-region S2, so that the second sub-pixel can be finally classified as the first sub-region S1. That is, the second sub-pixel divided into two parts by the boundary is finally classified as a sub-region in which the area of the sub-region is large.
In step 130, as shown in fig. 5, to more clearly illustrate how to select the second target sub-pixel from all the second sub-pixels in the first sub-region S1, four second repeating units 20 in 2 rows and 2 columns are taken as an example. 6 second sub-pixels among the 24 second sub-pixels of the four second repeating units 20 may be selected as the second target sub-pixels. For example, the four second repeating units 20 include four rows of second sub-pixels, and the first row and the third row of second sub-pixels may be selected, and further, the first row and the third row of second sub-pixels are selected alternately. As shown in fig. 5, the first row, the third row and the fifth row of the second sub-pixels in the first column are finally selected as the second target sub-pixel T20b of the second color, the second target sub-pixel T20c of the third color and the second target sub-pixel T20c of the first color, respectively; finally, the second sub-pixels in the second row, the fourth row and the sixth row of the second column are respectively selected as the second target sub-pixel T20c of the first color, the second target sub-pixel T20b of the second color and the second target sub-pixel T20c of the third color. Finally, the arrangement of the six second target sub-pixels selected in the four second repeating units 20 is the same as the arrangement of the six first target sub-pixels in the first repeating unit 10 of the first display area AA 1.
It should be understood that in fig. 4, 5 and 7, the second sub-pixel 20s is not selected as the second target sub-pixel in an unfilled shape, but the structure of the second sub-pixel and its corresponding pixel circuit still exist.
In addition, in step 130, as shown in fig. 4, for example, taking one second light-emitting combination unit 21 on the right side of the first display area AA1 as an example, the second light-emitting combination unit 21 includes one second target sub-pixel T20a of the first color, one second target sub-pixel T20b of the second color, and three second sub-pixels 20s that are not selected as the second target sub-pixels. There is one first light-emitting combination unit 11 in the first display area AA1, the first light-emitting combination unit 11 comprising one first target sub-pixel 10a of the first color, one first target sub-pixel 10b of the second color and three virtual sub-pixels 10 s. The second light-emitting combination unit 21 is identical to the first light-emitting combination unit 11.
Also for example, taking a second light-emitting combination unit 21 under the first display area AA1 as an example, the second light-emitting combination unit 21 includes a second target sub-pixel T20a of a first color, a second target sub-pixel T20b of a second color, a second target sub-pixel T20c of a third color, and six second sub-pixels 20s that are not selected as the second target sub-pixels. There is a first light-emitting combination unit 11 in the first display area AA1, the first light-emitting combination unit 11 comprising a first target sub-pixel 10a of the first color, a first target sub-pixel 10b of the second color, a first target sub-pixel 10c of the third color and six virtual sub-pixels 10 s. The second light-emitting combination unit 21 is identical to the first light-emitting combination unit 11.
That is, the number of the light-emitting sub-pixels, the color of the light-emitting sub-pixels, and the distribution positions of the light-emitting sub-pixels included in the second light-emitting combination unit 21 and the first light-emitting combination unit 11 are all the same, and the pixel density of the first sub-region S1 is the same as that of the first display region AA 1. In the first sub-area S1, a second light-emitting combination unit 21 is arbitrarily defined, and the same first light-emitting combination unit 11 as the second light-emitting combination unit 21 exists in the first display area AA 1.
It can be understood that the arrangement rule of the second target sub-pixels in the first sub-region S1 is the same as the arrangement rule of the first target sub-pixels in the first display region AA 1.
In step 140, the other areas except the selected area S in the second display area AA2, i.e. the non-selected area TS, are controlled to be displayed in a sub-pixel rendering manner. For better understanding of the sub-pixel rendering, please refer to fig. 6. Fig. 6 illustrates two adjacent second repeating units 20, each second repeating unit 20 includes two pixel units, and a total of four pixel units 201A, 201B, 201C, and 201D. The pixel unit 201A is controlled to display a certain gray level in a sub-pixel rendering manner, and the second sub-pixels of the surrounding pixel units 201B, 201C and 201D emit light to different degrees according to the set weight ratio due to the default relationship of the sub-pixel rendering algorithm. The area of the unselected area TS is much larger than the areas of the selected area S and the first display area AA1, and the unselected area TS is controlled to display in a sub-pixel rendering manner, so that the display panel as a whole can display with a higher resolution.
In step 140, the selected area S and the first display area AA1 are controlled to display in a second display mode, where the second display mode is a non-subpixel rendering mode. Thus, there is no luminance difference between the sub-pixels in the selected area S and the first display area AA1, and the luminance of the first target sub-pixels in the selected area S and the first display area AA1 can be independently and precisely controlled. And the other second sub-pixels in the first sub-region S1 except the second target sub-pixel are controlled to be in a non-light emitting state all the time, that is, the actual area of the first display region AA1 is enlarged, that is, the boundary of the first sub-region S1 becomes the actual display boundary of the first display region AA1, the boundary of the first sub-region S1 is in a preset curve, and the brightness of each sub-pixel of the first display region AA1 and the first sub-region S1 can be controlled independently, so that the actual boundary of the first display region AA1 has no sharp corner feeling, and the user experience is improved.
For example, the supply of the data signals to the second sub-pixels except for the second target sub-pixel in the first sub-region S1 may be stopped, so that the second sub-pixels except for the second target sub-pixel in the first sub-region S1 are in a non-emission state.

This is not a limitation of the present application.
It should be understood that the sub-pixels of the respective regions are provided with pixel circuits whether or not emitting light in the present application.

In some alternative embodiments, as shown in fig. 7, the size of the first target sub-pixel in the first repeating unit 10 may be increased to reduce the pixel density of the first display area AA1, so as to improve the light transmittance of the first display area AA 1.

In some alternative embodiments, as shown in fig. 4, the distance between the first target sub-pixels in the first repeating unit 10 may be increased to reduce the pixel density of the first display area AA1, so as to improve the light transmittance of the first display area AA 1. That is, the size of the first target sub-pixel in the first display area is the same as the size of the second target sub-pixel of the same color, and thus, the aperture ratio of the first target sub-pixel in the first display area is equal to the aperture ratio of the second target sub-pixel of the same color in the first sub-area, the display control method provided in the embodiment of the present invention may further include step 180: and under the same gray scale, controlling the brightness of the second target sub-pixel of the first sub-area to be equal to the brightness of the first target sub-pixel of the same color in the first display area.
