Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
At present, in order to realize a full screen of an electronic device, a camera under the screen is generally arranged. However, the off-screen camera generally performs hole digging or notch processing on the position of the display panel corresponding to the camera, and pictures cannot be displayed at the hole digging position, so that the display panel is presented as an incomplete screen, for example, a screen with a notch, a screen with a hole, which destroys the whole structure of the display panel, and the screen occupation ratio is still not high enough.
Based on this, the inventors have conducted a great deal of research on display panels of electronic devices. The inventor discovers that the display panel is provided with the display light transmission area, and the position corresponding to the display light transmission area of the display panel is provided with the camera under the screen, so that the user experience is improved.
For this reason, the inventors continued to study how to improve the photographing effect of the off-screen camera without affecting the display effect of the display panel. Among them, the research of the inventor includes: how to improve the luminousness of the display light-transmitting area, how to improve the photographing effect of the camera under the screen, and the like. After a lot of repeated comparison and research, the inventor further studied how to design a display panel capable of improving the screen ratio of the electronic device, and thus proposed the scheme of the embodiment of the present application.
Referring to fig. 1, an electronic device 100 is provided in the present embodiment, where the electronic device 100 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. The electronic device 100 of the present embodiment is described by taking a mobile phone as an example.
The electronic device 100 includes a housing 110, a display panel 200 and a function module 130, wherein the function module 130 is disposed on one side of the display panel 200, and the display panel 200 is connected to the housing 110. The housing 110 provides support for the display panel 200 and accommodates the function module 130. In this embodiment, the housing 110 and the display panel 200 together form an external appearance structure of the electronic device 100.
In the embodiment, the display panel 200 is a screen with a display function to display an interactive interface, an image, text information, etc. of the electronic device 100 for a user to view or operate, for example, the display panel 200 may be an Organic light Emitting Diode (Organic L light-Emitting Diode, O L ED) display screen.
The functional module 130 has a signal detection surface 131 for receiving or transmitting signals through the display panel 200. As an embodiment, the function module 130 includes at least one of a camera module, an ambient light sensor, a proximity sensor, and an optical fingerprint module to implement the related functions of the electronic device 100. For example, when the functional module 130 is a camera module, the functional module 130 performs image capturing, such as taking a picture or recording a video, through the display panel 200 via the signal detection surface 131, so as to implement the camera function of the electronic device 100.
Referring to fig. 1, the display panel 200 has a first display region 210, and a second display region 230 and a third display region 250 respectively disposed at two opposite sides of the first display region 210. In some embodiments, the second display area 230 and the third display area 250 may also be disposed together around the first display area 210.
In the present embodiment, taking the functional module 130 as an image capturing module as an example, the signal detection surface 131 of the functional module 130 is disposed opposite to the first display area 210 to receive or transmit signals through the first display area 210. At this time, the first display area 210 serves as an off-screen image pickup area of the electronic apparatus 100, and the second display area 230 and the third display area 250 serve as normal display areas of the electronic apparatus 100. It should be noted that the first display area 210, the second display area 230, and the third display area 250 are the area division that is done by the narrative party, and they may not have distinct boundaries on the display panel 200.
The under-screen image capture area and the normal display area may be distinguished by the difference of the light transmittances of the display areas of the display panel 200, for example, the light transmittance of the second display area 230 is equal to the light transmittance of the third display area 250, and the light transmittance of the first display area 210 is greater than the light transmittance of the second display area 230 and greater than the light transmittance of the third display area 250. In the present specification, the light transmittance is used to indicate the ability of the medium to transmit light, that is, to indicate the light transmittance when light passes through the first display region 210, the second display region 230, and the third display region 250. For example, taking the functional module 130 as a camera module as an example, the camera module disposed in the first display area 210 can receive more light, so as to improve the transmission efficiency of the optical signal of the first display area 210, and further improve the image capturing effect of the camera module disposed in the first display area 210.
Referring to fig. 2, the display panel 200 includes a plurality of pixels 220 arranged in an array, a signal line group 240 connected to the plurality of pixels 220, and a driving circuit 260 connected to the signal line group 240. The plurality of pixels 220 are arranged in the first display region 210, the second display region 230, and the third display region 250, and the signal line group 240 connects the plurality of pixels 220 and the driving circuit 260. In practical use, the driving circuit 260 is used for generating driving signals, and the driving signals drive the plurality of pixels 220 through the signal line group 240, so as to complete the display function of the display panel 200. For example, the driving signal generated by the driving circuit 260 can control a specific pixel on the display panel 200 to emit light, so as to combine to form a specific image, thereby implementing the display function of the electronic device 100.
The light transmittance of the first display region 210 is greater than that of the second display region 230 and greater than that of the third display region 250. In some embodiments, by setting the parameters of the arrangement density of the pixels of each display region, it can be achieved that each display region has different light transmittance, for example, the arrangement density of the pixels located in the first display region 210 is less than the arrangement density of the pixels located in the second display region 230, and less than the arrangement density of the pixels located in the third display region 250. In other words, the number of pixels of the first display region 210 is less than the number of pixels of the second display region 230 and less than the number of pixels of the third display region 250 in a unit area. Among them, the second display region 230 and the third display region 250 have a larger arrangement density of pixels ("larger" means compared with the arrangement density of the pixels of the first display region 210), and can reduce the light transmittance of the second display region 230 and the third display region 250 and improve the resolution of the second display region 230 and the third display region 250. Meanwhile, the arrangement density of the pixels of the first display region 210 is small ("small" means compared with the arrangement density of the pixels of the second display region 230 or the third display region 250), and more light can be allowed to transmit through the first display region 210, so that the light transmittance of the first display region 210 is improved while the display effect of the first display region 210 is ensured.
In other embodiments, the different light transmittances of the display regions may be achieved by controlling the physical properties of the pixels of the display regions, for example, the light transmittance of the pixels of the first display region 210 is greater than the light transmittance of the pixels of the second display region 230 and greater than the light transmittance of the pixels of the third display region 250, so that the light transmittance of the first display region 210 is greater than the light transmittance of the second display region 230 and greater than the light transmittance of the third display region 250. Specifically, the transmittance of the material of the pixels of the first display region 210 may be greater than the transmittance of the material of the pixels of the second display region 230 and greater than the transmittance of the material of the pixels of the third display region 250.
In this embodiment, referring to fig. 3, a single pixel of the plurality of pixels 220 arranged in an array may include at least one of a green sub-pixel 2201, a blue sub-pixel 2203 and a red sub-pixel 2205. For example, a single pixel may include a green sub-pixel 2201, a blue sub-pixel 2203 and a red sub-pixel 2205, and at this time, the driving signal of the driving circuit 260 may include control of different sub-pixels in the single pixel, so that different pixels in the plurality of pixels 220 may be lighted to form different colors to present different display effects, such as patterns, on the display panel 200.
Further, the plurality of pixels 220 includes a first column of pixels 221 and a second column of pixels 223, the first column of pixels 221 is arranged in the second display area 230, the first display area 210 and the third display area 250, and the second column of pixels 223 is arranged in parallel with the first column of pixels 221. It should be noted that "the first column of pixels 221" and "the second column of pixels 223" are illustrated as a single column of pixels in fig. 2, where "the first" and "the second" are definitions for descriptive purposes and are not actually limited. The number of pixels in fig. 2 is merely illustrative, and does not limit the number of actual pixels in the first column of pixels 221 and the second column of pixels 223.
Specifically, referring to fig. 4, the second row of pixels 223 includes a first pixel group 201 and a second pixel group 203, the first pixel group 201 is disposed in the second display area 230, and the second pixel group 203 is disposed in the third display area 250. The first row of pixels 221 includes a third pixel group 205, a fourth pixel group 207, and a fifth pixel group 209, the third pixel group 205 is disposed in the second display region 230, the fourth pixel group 207 is disposed in the first display region 210, and the fifth pixel group 209 is disposed in the third display region 250.
In this embodiment, each of the first pixel group 201, the second pixel group 203, the third pixel group 205, the fourth pixel group 207 and the fifth pixel group 209 includes at least one pixel, wherein the pixels of the first pixel group 201 and the pixels of the second pixel group 203 are arranged in the same direction to form a second column of pixels 223, and the pixels of the third pixel group 205, the pixels of the fourth pixel group 207 and the pixels of the fifth pixel group 209 are arranged in the same direction to form a first column of pixels 221. It should be noted that the first pixel group 201, the second pixel group 203, the third pixel group 205, the fourth pixel group 207, and the fifth pixel group 209 are partitions that pixels in different columns are located in different display areas, and are not limited in practice.
In the present embodiment, the first display region 210 is arranged with the fourth pixel group 207, the second display region 230 is arranged with the first pixel group 201 and the third pixel group 205, and the third display region 250 is arranged with the second pixel group 203 and the fifth pixel group 209. As an embodiment, as shown in fig. 2, the arrangement density of the pixels of the fourth pixel group 207 is smaller than the arrangement density of the pixels of the third pixel group 205 and smaller than the arrangement density of the pixels of the fifth pixel group 209, so that the arrangement density of the pixels located in the first display region 210 can be realized to be smaller than the arrangement density of the pixels located in the second display region 230 and smaller than the arrangement density of the pixels located in the third display region 250. Therefore, the light transmittance of the first display region 210 can be greater than the light transmittance of the second display region 230 and greater than the light transmittance of the third display region 250, so as to improve the transmission efficiency of the optical signal of the first display region 210, thereby facilitating the operation of the functional module 130 disposed in the first display region 210.
In another embodiment, as shown in fig. 4, the arrangement density of the pixels of the fourth pixel group 207 is equal to the arrangement density of the pixels of the third pixel group 205, and is equal to the arrangement density of the pixels of the fifth pixel group 209. Since the second display region 230 is further arranged with the first pixel group 201 and the third display region 250 is further arranged with the second pixel group 203, the arrangement density of the pixels in the first display region 210 is still smaller than the arrangement density of the pixels in the second display region 230 and smaller than the arrangement density of the pixels in the third display region 250. Therefore, the light transmittance of the first display region 210 can be greater than the light transmittance of the second display region 230 and greater than the light transmittance of the third display region 250, so as to improve the transmission efficiency of the optical signal of the first display region 210, thereby facilitating the operation of the functional module 130 disposed in the first display region 210.
Referring to fig. 4 again, the first row of pixels 221 may be a plurality of pixels, the second row of pixels 223 may be a plurality of pixels, the plurality of pixels 221 and the plurality of pixels 223 are alternately arranged in the first display region 210, and the second display region 230 and the third display region 250 are located at two opposite sides of the first display region 210.
Further, referring to fig. 5, the pixel density of the fourth pixel groups 207 of the first columns of pixels 221 follows the following rule: the pixel density of the fourth pixel group 207 farther from the geometric center of the first display region 210 is greater than or equal to the pixel density of the fourth pixel group 207 closer to the geometric center. It should be noted that the "geometric center" may be a position of a center point of a geometric shape formed by the first display area 210, and fig. 5 provided in this specification illustrates a schematic diagram in which O is taken as the geometric center of the first display area 210. Among them, since the fourth pixel group 207 having different pixel densities is disposed in the first display region 210, different regions of the first display region 210 may have different light transmittances, thereby providing different optical signal transmission efficiencies. In conjunction with fig. 4 and the above description, it can be seen that the second row of pixels 223 is not disposed in the first display region 210, so the second row of pixels 223 is not shown in fig. 5.
The signal line group 240 includes a first signal line group 241, a second signal line group 243, a third signal line group 245 and a controller 247, the first signal line group 241 connects the first column of pixels 221 and the driving circuit 260, and the second signal line group 243 connects the first pixel group 201 and the driving circuit 260. The third signal line group 245 is connected to the second pixel group 203 and is connected to the first signal line group 241 through the controller 247. The controller 247 controls the second pixel group 203 according to a driving signal of the driving circuit 260.
Specifically, the first signal line group 241 connects the driving circuit 260, the pixels in the third pixel group 205, the pixels in the fourth pixel group 207, and the pixels in the fifth pixel group 209 in order to realize transmission of the driving signal of the driving circuit 260, and controls the pixels in the third pixel group 205, the pixels in the fourth pixel group 207, and the pixels in the fifth pixel group 209. For example, the driving circuit 260 may control the pixels in the third pixel group 205, the pixels in the fourth pixel group 207, and any one of the pixels in the fifth pixel group 209 to be turned on or off or any one of the pixels to be displayed in a specific color (e.g., red, blue, green, etc.) through the transmission of the driving signal by the first signal line group 241.
Similarly, the second signal line group 243 sequentially connects the driving circuit 260 and the pixels of the first pixel group 201 to realize the transmission of the driving signal of the driving circuit 260 and control the pixels in the first pixel group 201. For example, the driving circuit 260 may control the on or off of any one of the pixels in the first pixel group 201 or control any one of the pixels to display in a specific color (e.g., red, blue, green, etc.) through the transmission of the driving signal through the second signal line group 243. Here, the first signal line group 241 and the second signal line group 243 can respectively control the pixels of the first pixel group 201 of the first column of pixels 221 and the second column of pixels 223, so as to form a specific pattern.
In this embodiment, the third signal line group 245 sequentially connects the controller 247 and the pixels of the second pixel group 203, and the controller 247 accesses the first signal line group 241. In actual use, the driving signal of the driving circuit 260 reaches the controller 247 via the first signal line group 241, and the controller 247 controls the pixels of the second pixel group 203 according to the driving signal. The controller 247 connects the second pixel group 203 to the first signal line group 241, so that the number of wires in the first display area 210 can be reduced, and the diffraction of the first display area 210 is reduced to improve the light transmittance of the first display area 210.
Further, the first display region 210 can be disposed at any position of the display panel 200 through the controller 247 and the third signal line group 245, that is, the function module 130 can be disposed in any region of the display panel 200. For example, the off-screen camera area may be provided in any region of the display panel 200. Also, the first display region 210 may perform display through the pixels of the fourth pixel group 207 connected by the first signal line group 241, so that the full screen display of the display panel 200 is performed. The first display region 210 can be disposed at any position of the display panel 200 through the controller 247 and the third signal line group 245, so that the screen occupation ratio of the display panel 200 is increased while the functions of the display electronic device 100 such as under-screen image capture are realized.
Referring to fig. 6, the controller 247 includes an input end 2401 and an output end 2403, the input end 2401 is connected to the fourth pixel group 207, the output end 2403 is connected to the fifth pixel group 209 and the second pixel group 203, the driving signal from the driving circuit 260 is input according to the input end 2401, and the fifth pixel group 209 and the second pixel group 203 at the output end 2403 are controlled. As shown in fig. 6, the output terminals 2403 may include a first output terminal 2402 and a second output terminal 2404, the first output terminal 2402 is connected to the fifth pixel group 209, and the second output terminal 2404 is connected to the second pixel group 203, so as to control different pixel groups through different output terminals 2403.
In the present embodiment, the pixels of the fifth pixel group 209 and the pixels of the second pixel group 203 are arranged in parallel and collectively form a matrix arrangement so as to have pixels located in the same row. The controller 247 controls the pixels of the fifth pixel group 209 and the pixels of the second pixel group 203 on or off line by line according to the driving signal of the driving circuit 260. As an embodiment, the controller 247 may selectively output the driving signal of the driving circuit 260 to the first and second output terminals 2402 and 2404 according to timing, so that the pixels of the fifth and second pixel groups 209 and 203 may be turned on or off in response to the driving signal.
For example, as shown in fig. 6, the pixel of the fifth pixel group 209 may include only a green sub-pixel 2201, and the pixel of the second pixel group 203 includes a blue sub-pixel 2203 and a red sub-pixel 2205 alternately arranged.
If a row of the third display region 250 is required to display green, the driving signals of the driving circuit 260 may include a turn-on signal for outputting the green sub-pixel 2201 to the first output terminal 2402 and a turn-off signal or a gray-scale signal for outputting to the second output terminal 2404, so that the blue sub-pixel 2203 and the red sub-pixel 2205 of the second pixel group 203 are not displayed. The above-mentioned lighting signal for outputting the green sub-pixel 2201 to the first output terminal 2402 and the off signal or the gray scale signal for outputting to the second output terminal 2404 may be signals alternately output to the fifth pixel group 209 and the second pixel group 203 by the controller 247 according to the timing, so as to control a certain line of the third display region 250 to display green.
Accordingly, if a row of the third display region 250 needs to be displayed with red, the driving signal of the driving circuit 260 may include a turn-on signal for outputting the red sub-pixel 2205 to the second output terminal 2404 and a turn-off signal or a gray-scale signal for outputting to the first output terminal 2402, so that the green sub-pixel 2201 of the fifth pixel group 209 does not display. The above-mentioned lighting signal for outputting the red sub-pixel 2205 to the second output terminal 2404 and the off signal or the gray scale signal for outputting to the first output terminal 2402 may be signals alternately output to the fifth pixel group 209 and the second pixel group 203 by the controller 247 according to the timing, so as to control a certain row of the third display region 250 to display red.
It should be noted that, since the red sub-pixels 2205 and the blue sub-pixels 2203 of the second pixel group 203 are alternately present, when the blue sub-pixels 2203 of the second pixel group 203 are present in the same row, the driving signal of the driving circuit 260 includes the off signal or the gray-scale signal output to the first output terminal 2402 and the second output terminal 2404, so that neither the blue sub-pixels 2203 nor the green sub-pixels 2201 of the row are displayed.
As an embodiment, the controller 247 may further include a switch unit (not shown in the figure) for controlling whether the driving signal of the driving circuit 260 enters the second pixel group 203 through the third signal line group 245, so as to control the pixels of the second pixel group 203. For example, the second pixel group 203 and the fifth pixel group 209 each include a red subpixel 2205, a green subpixel 2201 and a blue subpixel 2203, the driving signal of the driving circuit 260 includes lighting a certain subpixel of a certain row, and the fifth pixel group 209 can light the corresponding subpixel through the first signal line group 241.
