Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
Although exemplary embodiments of a display screen and a display device including a display screen have been particularly described herein, many modifications and variations will be apparent to those skilled in the art. It will thus be appreciated that a display screen and a display device including a display screen constructed in accordance with the principles of the present application may be implemented other than as specifically described herein, the application being further defined in the claims and their equivalents. As shown in FIG. 1, the display screen in one embodiment includes a first display area A1 and a second display area A2. The first display area a1 at least partially surrounds the second display area a2, in the second display area a2, each sub-pixel is connected to the power supply circuit of the sub-pixel through a transparent electrode trace, and the line width of the transparent electrode trace of each sub-pixel is smaller than the first trace distance between the transparent electrode trace of the sub-pixel and the transparent electrode trace of the adjacent sub-pixel. The transparent electrode is an electrode having high light transmittance and high conductivity in a visible light source.
In the second display area, each sub-pixel is connected with the power supply circuit of the sub-pixel through a transparent electrode wire, so that light can be transmitted out from the transparent electrode wires of the sub-pixels in the second display area, and the line width of the transparent electrode wire of each sub-pixel is smaller than the first wire distance between the transparent electrode wire of the sub-pixel and the transparent electrode wire of the adjacent sub-pixel, so that high light transmittance can be realized, and full-screen or full-screen display is realized. Both satisfied the requirement that the display screen normally shows, compromise the requirement that the position of placing photosensitive module under the screen need keep higher luminousness again, owing to photosensitive module reservation position under the screen need not, can save the non-display area, enlarge the screen and account for than, optimize and use the impression, solved the existence of non-display area and lead to user's use impression not good technical problem.
In one particular application of the display screen, it may be, for example, a display screen of a mobile phone. A conventional display screen of a mobile phone may include an area where a camera is disposed and an area mainly used for displaying an image. In the present application, the first display area a1 and the second display area a2 are formed on the display screen of the mobile phone, and both the first display area a1 and the second display area a2 can be used to display images, that is, the entire display screen can be displayed when the entire display screen is observed by naked eyes, that is, the entire display screen is a so-called full-screen. Because in the second display area a2, each sub-pixel is connected with the power supply circuit of the sub-pixel through the transparent electrode wire, so that light can be transmitted between the transparent electrode wires of each sub-pixel in the second display area, and because the line width of the transparent electrode wire of each sub-pixel is smaller than the first wire distance between the transparent electrode wire of the sub-pixel and the transparent electrode wire of the adjacent sub-pixel, the illumination intensity requirements of the photosensitive module under screens such as a front camera of a mobile phone can be met, no position is reserved for the front camera, so that a non-display area can be omitted, the screen occupation ratio is enlarged, the use experience is optimized, and the technical problem that the use experience of a user is poor due to the existence of the non-display area can be solved.
The arrangement of the sub-pixels in the second display region a2 may be the same as or different from the arrangement of the sub-pixels in the first display region a 1. The first area of the light-transmitting region formed by each sub-pixel in the second display region a2 may be larger than the second area of the shielding region formed by each sub-pixel in the second display region a 2. The sub-pixel may be any one of a red (R) sub-pixel, a green (G) sub-pixel, and a blue (B) sub-pixel. And each sub-pixel may be individually powered by a corresponding power supply circuit.
As shown in fig. 2, the display screen in one embodiment may further include a third display area A3, where the third display area A3 is disposed between the first display area a1 and the second display area a 2. Specifically, in some embodiments, the second display region a2 may be adjacent to the third display region A3 only, i.e., the first display region a1 is not directly adjacent to the third display region A3. In some embodiments, the second display region a2 may be partially adjacent to the third display region A3 and partially adjacent to the first display region a1, i.e., the portion of the second display region a2 is adjacent to the first display region a1 through the third display region. In fig. 2, a portion of the second display region a2 is illustrated as being adjacent to the first display region a1 via the third display region. Therefore, through the arrangement of the third display area A3, it is possible to perform arrangement related to transition boundaries, such as the design of routing lines, the arrangement of boundary sub-pixels, and the like, as a transition area between the first display area a1 and the second display area a2, for example, the lines related to the sub-pixels of the second display area are arranged below the third area.
The arrangement of the sub-pixels in the third display area A3 may be the same as the arrangement of the sub-pixels in the second display area a2, or the same as the arrangement of the sub-pixels in the second display area a1, which is not limited in this embodiment.
The shapes of the second display area and the third display area may be set according to actual needs, and fig. 1 and fig. 2 are both described by taking the second display area as a rectangle and the third display area as a rectangle, which is not intended to limit the shape of the second display area a2 in the present embodiment.
Referring to fig. 3, it is assumed that a width of the transparent electrode trace of a certain sub-pixel P1 in the second display area a2 is W1. In the sub-pixel P2 adjacent to the sub-pixel P1, the width of the transparent electrode trace is W1, and the distance between the transparent electrode trace of the sub-pixel P1 and the transparent electrode trace of the sub-pixel P2 is d, then d > W1, and d > W2. The first routing distance between the transparent electrode routing of the sub-pixel and the transparent electrode routing of the adjacent sub-pixel refers to the distance between the transparent electrode routing of the sub-pixel and the adjacent edge of the transparent electrode routing of the adjacent sub-pixel.
In one embodiment, the line widths of the transparent electrode traces of the sub-pixels may be the same or different. Specifically, as shown in fig. 3, the width w1 of the transparent electrode trace of the subpixel P1 may be the same as the width w2 of the transparent electrode trace of the subpixel P2, or w1 ≠ w2, or may be different, that is, w1 ≠ w 2.
In some embodiments, the line width of the transparent electrode trace of the sub-pixel ranges from 1 to 50 micrometers. Specifically, in some specific examples, the line width of the transparent electrode trace of the sub-pixel is 10 micrometers.
In some embodiments, the first trace pitch has a value ranging from 1 to 100 micrometers. Specifically, in some specific examples, the first trace pitch is 50 microns.
When the transparent electrode wire of the sub-pixel and the transparent electrode wire of the adjacent sub-pixel are not in the same layer, the first wire pitch is a projection pitch when the transparent electrode wire of the sub-pixel and the transparent electrode wire of the adjacent sub-pixel project to the same plane. Therefore, under the condition that the transparent electrode wires are not on the same layer, the projection distance is ensured, and light can be ensured to penetrate through the projection gap between the transparent electrode wires, so that the light transmittance is ensured.
In one embodiment, the transparent electrode trace of one sub-pixel comprises at least two sub-transparent electrode traces. Due to the high impedance of the transparent electrode traces, if the length of the transparent electrode traces is long, and the width of the transparent electrode traces is affected, the driving voltage finally reaching the sub-pixels is easily reduced, the supply current is insufficient, and the light emission of the sub-pixels is affected. Therefore, by combining the arrangement condition of the sub-pixel routing in the actual technical scene, more than two sub-transparent electrode routing can be arranged for the sub-pixel, so as to meet the requirement of the sub-pixel on the supply current.
Under the condition that the transparent electrode routing of the sub-pixels comprises at least two sub-transparent electrode routing lines, the line width of any one sub-transparent electrode routing line is smaller than the second routing line distance between the sub-transparent electrode routing line and the adjacent sub-transparent electrode routing line.
Referring to fig. 4, it is assumed that a transparent electrode trace of a certain sub-pixel P1 in the second display area a2 includes two sub-transparent electrode traces, the widths of the two sub-transparent electrode traces are w11 and w12, respectively, and the distance between the two sub-transparent electrode traces of the sub-pixel P1 is d 1. The transparent electrode trace of the sub-pixel P2 adjacent to the sub-pixel P1 includes two sub-transparent electrode traces, the widths of the two sub-transparent electrode traces are w21 and w22, respectively, and the distance between the two sub-transparent electrode traces of the sub-pixel P2 is d 2. Then there are d1> w11, d1> w12, d2> w21, and d2> w 22. The distance between the transparent electrode trace and the transparent electrode trace of the sub-pixel P2 is d, and d > w1 and d > w 2. The second routing distance between the sub-transparent electrode routing lines of the sub-pixels refers to the distance between adjacent edges of the adjacent sub-transparent electrode routing lines of the sub-pixels.
In one embodiment, the line widths of the sub transparent electrode traces of the sub pixels may be the same or different. Specifically, as shown in fig. 4, the widths w11 and w12 of the two sub transparent electrode traces of the sub pixel P1 may be the same or different. The widths w21 and w22 of the two sub-transparent electrode traces of the sub-pixel P2 may be the same or different. The sub-transparent electrodes of the sub-pixel P1 and the sub-transparent electrode of the sub-pixel P2 may be the same or different. Taking the example shown in fig. 4 as an example, the width w11 of the sub-transparent electrode trace of the sub-pixel P1 may be the same as or different from the width w12 of the sub-transparent electrode trace of the sub-pixel P2.
When the sub-transparent electrode wires and the adjacent sub-transparent electrode wires are not in the same layer, the second wire pitch is a projection pitch when the sub-transparent electrode wires and the adjacent sub-transparent electrode wires project to the same plane. Therefore, under the condition that the sub-transparent electrode wires are not in the same layer, the projection space is ensured, and light can be ensured to penetrate through the projection gap between the sub-transparent electrode wires, so that the light transmittance is ensured.
In an embodiment, when the transparent electrode traces of the sub-pixels include at least two sub-transparent electrode traces, the first trace pitch is a pitch between a sub-transparent electrode trace of the sub-pixel adjacent to an adjacent sub-pixel and a transparent electrode trace of the adjacent sub-pixel. Specifically, referring to fig. 4, the first trace pitch d between the sub-pixel P1 and the sub-pixel P2 refers to a boundary distance between the sub-transparent electrode trace with the width w12 and the sub-transparent electrode trace with the width w 21.
In some embodiments, the line width of the sub transparent electrode trace ranges from 1 to 50 micrometers. Specifically, in some specific examples, the line width of the transparent electrode trace of the sub-pixel is 10 micrometers.
In some embodiments, the value range of the second trace pitch is 1 to 100 micrometers. Specifically, in some specific examples, the second trace pitch is 30 microns.
Due to the requirement of layout design, when the transparent electrode wires of the sub-pixels are connected to the power supply circuit, the transparent electrode wires of the sub-pixels may not be all connected to the power supply circuit in a straight line manner, but may be connected to the power supply circuit in an arbitrary wiring manner, for example, the transparent electrode wires may have a certain bend, so as to reduce the problem of diffraction caused by the wiring wires. Under the condition that the sub-transparent electrode wires of the sub-pixels are connected to the power supply circuit in an arbitrary wiring mode, the self-spacing of the transparent electrode wires of the sub-pixels is larger than the line width of the transparent electrode wires of the sub-pixels. The self-spacing of the transparent electrode traces of the sub-pixels refers to a boundary distance between one part of the traces and the other part of the traces of the transparent electrode traces of the sub-pixels.
Specifically, as shown in fig. 5, the transparent electrode trace of the sub-pixel P1 of the second display area a2 is connected to the power supply circuit by way of a bend, the width of the transparent electrode trace is w0, and the self-spacing at a certain bend is d0, so that d0> w 0. It should be understood that the transparent electrode trace of the sub-pixel P1 may have a plurality of different self-pitches in the actual wiring, and each self-pitch may not be the same, and each self-pitch needs to be larger than the width of the transparent electrode trace.
It should be understood that, in the case that the transparent electrode traces of the sub-pixels are connected to the power supply circuit in a bending manner, the first trace pitch between the transparent electrode traces of the adjacent sub-pixels as described above refers to a distance between the transparent electrode traces of the sub-pixels at any routing position, that is, at any position of the second display area a2, a distance between any two adjacent transparent electrode traces needs to be greater than a line width of the transparent electrode trace.
Correspondingly, in some embodiments, the sub-transparent electrode traces of the sub-pixels may also be connected to the power supply circuit in any wiring manner, and at this time, the self-spacing of the sub-transparent electrode traces of the sub-pixels is greater than the line width of the sub-transparent electrode traces of the sub-pixels. As described above, the second routing distance between the sub-transparent electrode traces refers to a distance between two sub-transparent electrode traces at any routing position, that is, at any position of the second display area a2, a distance between any two adjacent sub-transparent electrode traces needs to be greater than a line width of the sub-transparent electrode trace.
In some embodiments, the self-spacing can range from 1 to 100 microns. Specifically, in some specific examples, the self-spacing is 30 microns.
As shown in fig. 6, in an embodiment, a driving method of a display screen is further provided, where the display screen includes a first display area and a second display area, the first display area at least partially surrounds the second display area, in the second display area, each sub-pixel is connected to a power supply circuit of the sub-pixel through a transparent electrode trace, and a line width of the transparent electrode trace of each sub-pixel is smaller than a first trace pitch between the transparent electrode trace of the sub-pixel and a transparent electrode trace of an adjacent sub-pixel. The driving method of the display panel includes the following steps S601 to S603.
Step S601: receiving driving signals of sub-pixels of a display screen.
Step S602: and when the sub-pixel corresponding to the driving signal is in the first display area of the display screen, driving the sub-pixel corresponding to the first display area through the corresponding transparent electrode by using the driving signal. In some embodiments, the corresponding address information may be looked up in the drive signal. Based on the address information, it is determined whether the sub-pixel driven by the driving signal is in the first display region a1 or the second display region a 2.
Step S603: and when the sub-pixels corresponding to the driving signals are located in a second display area of the display screen and the second display area meets the light transmission condition currently, correcting the driving signals, and driving the corresponding sub-pixels of the second display area through the corresponding transparent electrode routing lines by using the corrected driving signals.
Thus, when the display screen is driven, for each sub-pixel in the first display region, normal driving using a driving signal is possible. And for the sub-pixels located in the second display area, when the second display area currently meets the light transmission condition, namely the second display area needs to transmit light, the light-emitting brightness of the second display area is reduced by modifying the driving signal, so that the light transmission requirement of the light ray transmitting the second display area can be met, meanwhile, the influence of the light emission of the sub-pixels of the second display area on light transmission is avoided, and the light transmission effect is improved.
It is understood that when the sub-pixel corresponding to the driving signal is in the second display area of the display screen, and the second display area does not currently satisfy the light transmission condition, the sub-pixel corresponding to the first display area can be driven by using the driving signal.
Specifically, when the drive signal is corrected as described above, the correction may be performed in various possible manners as long as the light emission luminance of the second display region can be reduced. In some specific examples, modifying the driving signal and driving the corresponding sub-pixel of the second display region using the modified driving signal includes:
and disconnecting the driving signal to make the sub-pixel of the second display area not emit light.
Therefore, when the second display area needs to be subjected to light transmission, the driving signals of the sub-pixels of the second display area are directly cut off, so that the sub-pixels of the second display area do not emit light, the influence of the light emission of the sub-pixels of the second display area on the light transmission can be effectively avoided, and the light transmission effect is improved.
The above-mentioned light transmission condition can be set in combination with actual technical requirements. In some embodiments, it may be determined that the light-transmitting condition is satisfied when the device in which the display screen is located is in a photographing mode. The device where the display screen is located may be a recognized possible device, such as a mobile phone, a tablet computer, a telephone watch, a wearable device, and the like, and the embodiment of the present application does not limit the specific form of the device.
There is also provided in one embodiment a display device including:
a display screen as described above;
photosensitive module under the screen, photosensitive module sets up under the screen the second display area's of display screen below, photosensitive module can respond to under the screen and pass the light that the second display area of display screen shines into.
The display screen and the second display area have already been explained in detail in the foregoing, and are not described again here.
It is to be understood that the display device herein may be understood as a standalone product, such as any product or component with a display function, for example, an OLED display device, a QLED display device, electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, a wearable device, an internet of things device, and the like, and the embodiments disclosed in this application are not limited thereto. The display device may also include a dc power source, a dc or ac power source interface, memory, a processor, etc.
In one specific application, the under-screen photosensitive module may be a device including a camera, a photosensor, and the like. The photoelectric sensor may specifically be an infrared sensor for measuring whether the face of a person is close to the display screen.
As described above, the display screen includes the first display area and the second display area, and in the second display area, each sub-pixel is connected to the power supply circuit of the sub-pixel through the transparent electrode wire, so that the light can be transmitted out from between the transparent electrode wires of each sub-pixel in the second display area, and because the line width of the transparent electrode wire of each sub-pixel is smaller than the first wire distance between the transparent electrode wire of the sub-pixel and the transparent electrode wire of the adjacent sub-pixel, a higher light transmittance can be achieved, and thus, full-screen or full-screen display is achieved.
