Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. 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.

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.

At present, when sub-pixels of adjacent areas of a light-transmitting display area and a non-light-transmitting display area are driven, the problem of mutual interference exists, and the display effect of a display panel is influenced.

In order to solve the above problems, embodiments of the present invention provide a display panel and a display device, and the following describes embodiments of the display panel and the display device with reference to the accompanying drawings.

Embodiments of the present invention provide a display panel, which may be an Organic Light Emitting Diode (OLED) display panel.

In order to clearly show the arrangement of the data lines, the scan lines are shown hidden in the drawings.

Fig. 1 illustrates a schematic top view of a display panel provided according to an embodiment of the present invention, and fig. 2 illustrates an exemplary enlarged view of a portion of a Q region in fig. 1.

As shown in fig. 1, 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, it is preferable that the light transmittance of the first display area AA1 is 15% or more. In order to ensure that the light transmittance of the first display area AA1 is greater than 15%, even greater than 40%, or even higher, in this embodiment, the light transmittance of at least some functional film layers of the display panel 100 is greater than 80%, and even greater than 90%.

According to the display panel 100 of the embodiment of the invention, the light transmittance of the first display area AA1 is greater than that of the second display area AA2, so that the display panel 100 can integrate a photosensitive component on the back of the first display area AA1, and realize the under-screen integration of the photosensitive component such as a camera, and meanwhile, the first display area AA1 can display a picture, so that the display area of the display panel 100 is increased, and the full-screen design of the display device is realized.

As shown in fig. 1 and 2, the display panel 100 includes a substrate 20, scan lines, and data lines. The plurality of scan lines extend in the first direction X on the substrate 10 and are spaced apart from each other. The plurality of data lines extend in a second direction Y intersecting the first direction X on the substrate 10 and are spaced apart from each other. The data lines include a first type data line 31, a second type data line 32, and a third type data line 33. The first type data lines 31 and the second type data lines 32 extend in the second display area AA2, the third type data lines 33 include a first segment 331 and a second segment 332 connected to each other, the first segment 331 is located in the first display area AA1, the second segment 332 is located in the second display area AA2, and at least a portion of the virtual extension lines of the second type data lines 32 are located at an edge of the first display area AA1 adjacent to the second display area AA2 in the first direction X.

Illustratively, the first display area AA1 includes a plurality of first sub-pixels 110, and the second display area AA2 includes a plurality of third sub-pixels 130. In order to improve the light transmittance of the first display area AA1, the distribution density of the first sub-pixels 110 may be less than that of the third sub-pixels 130. For example, in the first direction X, the number of columns of the third sub-pixels 130 in the width range of the first display area AA1 may be M times the number of columns of the first sub-pixels 110, where M is a positive integer greater than or equal to 2. Further, a scan line (not shown) is electrically connected to the first sub-pixel 110 and the third sub-pixel 130, and the scan line provides a scan signal for the first sub-pixel 110 and the third sub-pixel 130.

The first data line 31 and the second data line 32 only extend in the second display area AA2, that is, the first data line 31 and the second data line 32 are electrically connected to the third sub-pixel 130 only, and only provide data signals for the third sub-pixel 130. The third type data line 33 includes a first segment 331 and a second segment 332 connected to each other, the first segment 331 is electrically connected to the first sub-pixel 110, the second segment 332 is electrically connected to the third sub-pixel 130, and the third type data line 33 provides data signals for the first sub-pixel 110 and the third sub-pixel 130.

As shown in fig. 2, the two virtual extension lines respectively having the second type data lines 32 are located at the left side edge and the right side edge of the first display area AA1 adjacent to the second display area AA2, and the two second type data lines 32 separate the first type data line 31 of the second display area AA2 from the second section 332 of the third type data line 33 of the first display area AA1, so as to avoid mutual interference between the first type data line 31 and the second section 332 of the third type data line 33, further avoid mutual interference between the data driving signals of the first display area AA1 and the second display area AA2, and improve the display effect of the display panel.

In some embodiments, as shown in fig. 3 and 4, the first display area AA1 includes a transparent display area 01 and a transition display area 02, and the transition display area 02 is located between the transparent display area 01 and the second display area AA 2. The first sub-pixels 110 are located in the transmissive display region 01, the second sub-pixels 120 are located in the transitional display region 02, and the third sub-pixels 130 are located in the second display region AA 2.

The pixel arrangement structure of the first sub-pixel 110, the pixel arrangement structure of the second sub-pixel 120, and the pixel arrangement structure of the third sub-pixel 130 are the same and all of the pixel arrangement structures are shared by the sub-pixels.

In some embodiments, the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 respectively include a plurality of different colors. In fig. 2, 4, 5, and 6, the sub-pixels of different colors are distinguished by different filling patterns, wherein the sub-pixels of the same color are drawn by the same filling pattern.

For example, the first sub-pixel 110 may include a red first sub-pixel 110, a green first sub-pixel 110, and a blue first sub-pixel 110. The second sub-pixel 120 includes a red sub-pixel 120, a green sub-pixel 120, and a blue sub-pixel 120. The third sub-pixel 130 includes a red third sub-pixel 130, a green third sub-pixel 130, and a blue third sub-pixel 130.

As shown in fig. 4, the arrangement of the first sub-Pixels 110 of each color, the arrangement of the second sub-Pixels 120 of each color, and the arrangement of the third sub-Pixels 130 of each color are the same, so that a boundary between the second display area AA2 with a higher pixel density (Pixels Per inc, PPI) and the first display area AA1 with a lower PPI in the display image of the display panel 100 can be blurred, thereby preventing a distinct boundary from appearing between the two display areas and improving the display effect.

For example, as shown in fig. 4, in the second display area AA2, the third pixel unit U3 includes a red third sub-pixel 130, a green third sub-pixel 130 and a blue third sub-pixel 130 in an adjacent column, and the blue third sub-pixel 130 and the red third sub-pixel 130 and the green third sub-pixel 130 in the adjacent column on the right side form a third pixel unit U3. That is, the one blue third subpixel 130 is commonly formed as two third pixel units U3. Similarly, the first Sub-pixels 110 in the transparent display area 01 are also shared, so that the first Sub-pixels 110 can be driven by using a Sub Pixel Rendering (SPR) technique, and the actual PPI of the first display area AA1 can be increased while the light transmittance of the transparent display area 01 is ensured, thereby improving the display effect of the transparent display area. Similarly, the second sub-pixel 120 in the transitional display area 01 is also commonly used, and the SPR technology can be similarly used to drive the second sub-pixel 120, so as to improve the display effect of the transitional display area 02.

The pixel density of the second display area AA2 is different from that of the first display area AA1, and in order to reduce the display difference between the second display area AA2 and the first display area AA1, different luminances are provided for the sub-pixels of the two display areas, and if the sub-pixels in the adjacent positions of the two areas are shared, the display effect of the display panel is adversely affected due to the different luminances. In the embodiment of the present invention, as shown in fig. 4, the two virtual extension lines of the second type data lines 32 are located at the edges of the light-transmitting display area 02 adjacent to the second display area AA2, and the two second type data lines 32 separate the first type data line 31 of the second display area AA2 from the first section 331 of the third type data line 33 of the light-transmitting display area 02, so as to avoid the sharing between the adjacent third sub-pixel 130 and the second sub-pixel 120, further avoid the mutual interference between the data driving signals of the first display area AA1 and the second display area AA2, and improve the display effect of the display panel.

In some embodiments, as shown in fig. 4, the color arrangement order of the first sub-pixels 110 corresponding to the first segment 331 in the second direction Y is the same as the color arrangement order of the third sub-pixels 130 corresponding to the second segment 332 in the second direction Y.

According to the embodiment of the present invention, the third type data line 33 provides data driving signals for the first sub-pixel 110 in the first display area AA1 and the third sub-pixel 130 in the second display area AA2 at the same time, and the color arrangement sequence of the first sub-pixel 110 corresponding to the first segment 331 of the third type data line 33 is the same as the color arrangement sequence of the third sub-pixel 130 corresponding to the second segment 332 in the second direction Y, so that the complexity of the driving algorithm can be reduced, the display difference between the two display areas can be further reduced, and the display effect of the display panel can be improved.

In some embodiments, in order to avoid the sharing of the sub-pixels of the transmissive display region 01 and the sub-pixels of the transition display region 02, the second type data lines 32 of the transmissive display region 01 and the second type data lines 32 of the transition display region 02 may be arranged as follows.

In a first arrangement, as shown in fig. 5, at least some of the virtual extension lines of the second type data lines 32 are located at the edge of the light-transmitting display area 01 adjacent to the transition display area 02 in the first direction X.

In a second arrangement, as shown in fig. 4, at least some of the virtual extension lines of the second type data lines 32 are located at the edge of the transitional display area 02 adjacent to the light-transmitting display area 01 in the first direction X.

In a third arrangement, at least a part of the virtual extension lines of the second type data lines 32 are located at the edge of the transparent display area 01 adjacent to the transitional display area 02 in the first direction X, and at least a part of the virtual extension lines of the second type data lines 32 are located at the edge of the transitional display area 02 adjacent to the transparent display area 01 in the first direction X.

According to the embodiment of the invention, the first sub-pixel 110 and the second sub-pixel 120 which are adjacent to each other can be prevented from sharing, and then the mutual interference of the data driving signals of the transparent display area 01 and the transition display area 02 can be avoided, and the display effect of the display panel can be improved.

In some embodiments, the transparent conductive structure is disposed in the transparent display region 01, the first segment 331 of the scan line and/or the third type data line 32. For example, the material of the transparent conductive structure may include Indium Tin Oxide (ITO) or Indium zinc Oxide. The scanning lines and the data lines of the light-transmitting display area 01 are arranged to be transparent conductive structures, so that the light transmittance of the light-transmitting display area can be further improved.

In some embodiments, as shown in fig. 6, the display panel 100 includes a first pixel circuit 140. The first pixel circuit 140 is located in the transitional display area 02, and the first pixel circuit 140 is electrically connected to the first sub-pixel 110 and is used for driving the first sub-pixel 110 to display. Furthermore, the first segment 331 of the third type data line 33 is located in the transition display area 01, and the scan line is located in the transition display area 02 and the second display area AA 2.

According to the embodiment of the invention, the first pixel circuit 140 corresponding to the first sub-pixel 110 in the transparent display area 01 is disposed at the periphery of the transparent display area 01, and the data line and the scan line are not disposed in the transparent display area 01, so that the light transmittance of the transparent display area 01 can be further improved.

In some embodiments, the first pixel circuit 140 can be electrically connected to the first sub-pixel 110 through a transparent wire, and the transparent wire is used to further improve the light transmittance of the light-transmitting display region 01.

In some embodiments, the circuit structure of the first pixel circuit 140 is any one of a 2T1C circuit, a 7T1C circuit, a 7T2C circuit, or a 9T1C circuit. Herein, the "2T 1C circuit" refers to a pixel circuit including 2 thin film transistors (T) and 1 capacitor (C) in the pixel circuit, and the other "7T 1C circuit", "7T 2C circuit", "9T 1C circuit", and the like are analogized.

In some embodiments, as shown in fig. 2, two second type data lines 32 are disposed between one first type data line 31 closest to the first display area AA1 and the second segment 332 of one third type data line 33 closest to the second display area AA2 in the first direction X. In the first direction X, the number of the second type data lines 32 between one first type data line 31 closest to the first display area AA1 and the second segment 332 of one third type data line 33 closest to the second display area AA2 may be set to other values according to actual requirements, and as long as the second type data line 32 is spaced between the two, the first type data line 31 and the first segment 331 of the third type data line 33 may be prevented from interfering with each other.

In some embodiments, the pixel density of the transitional display area 02 is less than the pixel density of the second display area AA2, and the pixel density of the transitional display area 02 is greater than or equal to the pixel density of the transmissive display area 01. The display difference between the second display area AA2, the transition display area 02 and the light-transmitting display area 01 is reduced, and the display uniformity is improved.

In some embodiments, the size of the second sub-pixel 120 is the same as that of the third sub-pixel 130 of the same color, so that the display difference between the transition display area a02 and the second display area AA2 is reduced, and the display uniformity is improved.

In some embodiments, the size of the first sub-pixel 110 is smaller than the size of the second sub-pixel 120 of the same color. The area of the non-light-emitting region in the light-transmitting display region 01 is made larger, which is convenient for further improving the light transmittance of the light-transmitting display region 01. It is understood that in other embodiments, the size of the first sub-pixel 110 is not limited thereto, and may be the same as the size of the second sub-pixel 120 of the same color, for example.
