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. It is to be understood that the specific embodiments described herein are illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

1) Pixel: indivisible units or elements in the entire image; the image is made up of these pixel tiles, each tile having a distinct location and assigned color value, the color and location of which determine how the image appears.

2) Pixel density (Pixels Per inc, PPI): density units of pixels, expressed as the number of pixels owned per inch; the higher the PPI value is, the higher the density of the image displayed on the display screen is, and the more detailed the picture is.

3) Active-matrix organic light-emitting diode (AMOLED) display screen: a series of organic thin film materials are used between the anode and the cathode, so that the luminous effect is achieved. The AMOLED needs to emit various colors by means of TFTs after adjusting the ratio of the three primary colors of the pixel.

4) A pixel circuit: at present, two driving circuit structures of a TFT circuit of 2T1C and a TFT circuit of 7T1C are commonly adopted in a pixel driving circuit.

Exemplarily, fig. 1 is a schematic diagram of a 2T1C driving circuit in the related art, and as shown in fig. 1, the TFT driving circuit of 2T1C includes a storage capacitor C1, a driving TFT, a T1, a switching TFT, a T2, an OLED, and various layout traces, and its operation principle is as follows: when the scanning line is selected, T2 is turned on, the data line data (voltage) charges the storage capacitor through T2, and the voltage of the storage capacitor controls the drain current of the driving T1 for supplying power to the OLED; when the scan line is not selected, the switch T2 is turned off, the charge stored in the storage capacitor keeps driving the gate voltage of T1, and the driving T1 keeps on state to continue supplying power to the OLED. Therefore, the OLED is in constant current control throughout the frame period.

Exemplarily, fig. 2 is a schematic diagram of a 7T1C driving circuit in the related art, as shown in fig. 2, in the TFT driving circuit of 7T1C, a storage capacitor C1 is included, three driving TFTs include T1, T5, and T6, four reset and control TFTs include T2, T3, T4, and T7, an OLED, and various layout traces, specifically, the basic operation principle thereof includes three operation phases of capacitor discharging, compensation, and OLED lighting, when in the capacitor discharging phase, the storage capacitor C1 is at a low potential, the T4 is turned on, the drain of T4 is at a low potential, and the capacitor C1 is discharged; when in the compensation phase, the source of T3 is low, T2 and T3 are turned on, the drain and gate of T1 are shorted, Vg > Vth, and T1 is turned on until Vg ═ Vdata-Vth; when in the light-emitting stage of the OLED, the sources of T5 and T6 are at low potential, T5 and T6 are turned on, and Vgs is ELVDD- (Vdata-Vth).

Further, compared with the TFT circuit of 7T1C, the 2T1C circuit has a problem that Vth dispersion of TFT tubes cannot be eliminated, resulting in non-uniform luminance of a screen, and thus the current circuit mostly adopts the TFT circuit of 7T 1C.

5) A multi-division signal output selector (De-multiplexer, MUX) circuit: for selecting the desired output signal, typically for switching the output of the Data signal. The MUX circuit is close to the IC at the lower end of the screen, and the purpose is to use the IC to drive higher resolution by using fewer data Source lines, such as 1: the 2MUX is used for interpretation, namely 1 data line is matched with the MUX circuit to drive 2 lines. The existing scheme comprises 1: 2. 1: 3. 1: 6, the watch uses 1: 12.

for example, fig. 3 is a schematic structural diagram of a display screen in the related art, as shown in fig. 3, the display screen 10 includes an Active Area (AA) 11 and a non-display area 12 located around the AA, and further, the display screen 10 further includes a MUX circuit 13 below the display area and a display driver chip (DDIC) 14 electrically connected to the MUX circuit 13.

Specifically, fig. 4 is a schematic diagram of an operating principle of a MUX circuit in the related art, where G is a green sub-pixel unit, R is a red sub-pixel unit, and B is a blue sub-pixel unit, as shown in fig. 4, the operating principle of the MUX circuit 13 is as follows: a data line needs to switch data signals twice within the driving time of one row, if a green picture needs to be displayed, when the row of scan (n) is scanned, the first half section G port opened by the signals is opened first, and the first MUX circuit and the second MUX circuit output gray scale signals corresponding to the green picture so as to drive the sub-pixel G; and when the second half of the signal comes, the R/B port is opened, and the first MUX circuit and the second MUX circuit input 0 gray scale signals to ensure that the R/B sub-pixel does not emit light.

If a red picture needs to be displayed, when the line Scan (n) is scanned, the first half G port of the signal opening is opened first, and the first MUX circuit and the second MUX circuit output 0 gray scale signals; when the second half of the signal is reached, the R/B port is opened, and the first MUX circuit inputs 0 gray scale signals to ensure that the B sub-pixels of the corresponding row do not emit light; simultaneously, the second MUX circuit inputs a red gray scale signal to enable the red sub-pixels of the corresponding row to start to emit light; the same is true when the Scan (n +1) line is scanned, except that the gray-scale signals output by the first MUX circuit and the second MUX circuit are alternated, so that a red picture can be displayed. Further, the principle of displaying a blue picture is similar to that of displaying a red picture, except that the gray-scale signals output by the first MUX circuit and the second MUX circuit are alternated.

Specifically, fig. 5A is a schematic position diagram of a lower-screen image pickup region in the related art, as shown in fig. 5A, a display screen includes a normal display region with a high PPI and a local display region (lower-screen image pickup region) where a camera is disposed below the screen with a low PPI, and the lower-screen image pickup region is disposed in a manner of being attached to a top, that is, the lower-screen image pickup region is tightly attached to a top end of the display screen; fig. 5B is a schematic diagram of a position of a lower-screen image capture area in a display screen in the related art, where as shown in fig. 5B, the display screen includes a normal display area and a lower-screen image capture area, and the lower-screen image capture area is set in a non-overhead manner, that is, in the display screen, a normal display area with high pixel density is further disposed at the upper end of the lower-screen image capture area.

Further, based on fig. 5A and 5B, fig. 6A and 6B are a first schematic diagram and a second schematic diagram of routing of the under-screen image capture region in the related art, respectively, where a gray-filled rectangle represents a pixel, and an unfilled dotted-line box represents a non-pixel gap, as shown in fig. 6A, when the under-screen image capture region adopts a roof-mounted arrangement as shown in fig. 5A, since the under-screen image capture region is a low-pixel-density region and there is no normal display region with a high pixel density above the image capture region, the data lines in the normal display region below the under-screen image capture region do not need to pass through the under-screen image capture region entirely, but only the data lines at positions where the under-screen image capture region has pixels are retained, that is, the data lines at positions where the under-screen image capture region has no pixels are discarded, as can be seen, only the data lines S1 and S3 at positions where the under-screen image capture region has pixels are retained in fig. 6, but directly discards S2 and S4. As shown in fig. 6B, when the under-screen image capturing area is set in the non-vertex-to-vertex manner as shown in fig. 5B, although the under-screen image capturing area is a low-pixel-density area, since a normal display area with a high pixel density is also provided above the under-screen image capturing area, in order to drive the pixels of the normal display area above the under-screen display area, the data lines below the under-screen display area need to pass through the under-screen image capturing area while maintaining the original structure, and connect each row of pixel circuits located on the upper and lower sides of the under-screen image capturing area and in the normal display area. As can be seen, in fig. 6B, the four data lines S1, S2, S3, and S4 remain in the under-screen image pickup region.

Therefore, the top-attaching setting has the effects of reducing the diffraction of the wiring and improving the transmittance of the shooting area, but the top-attaching setting of the shooting area under the screen has the problems of limiting the position of the camera under the screen and poor display effect of the UI status bar; correspondingly, the non-top-attaching setting of the area of making a video recording under the screen can make the camera set up in optional position under the screen to UI status bar display effect is good, and is visible, and the problem that the top-attaching setting exists can be solved in the non-top-attaching design of the area of making a video recording under the screen, but when the non-top-attaching setting, the walking line of the area of making a video recording under the screen increases, has strengthened walking line diffraction, thereby has leaded to the lower defect of the district's transmissivity of making a video recording under the screen. Therefore, there is a need for a display screen that can not only prevent the position of the camera under the screen from being limited, but also ensure good transmittance of the image area under the screen.

In order to solve the problems of the existing display screen, the embodiment of the application provides a display screen, a terminal and a display method. Specifically, in a third display area which is between the first display area and the second display area of the display screen and has low pixel density, pixels and a MUX circuit are arranged at the same time, so that when the lower-screen image pick-up area is in non-top-mounted arrangement, pixels which are located above the second display area and in a partial area of the first display area can be controlled by the MUX circuit under the condition that wiring of the second display area is not increased; meanwhile, the MUX circuit is located in the third display area and is not overlapped with the pixels, and the display effect of the display screen can be further guaranteed. It is thus clear that the display screen that this application provided can realize simultaneously the nimble setting of camera position under the screen to and the regional good transmissivity of making a video recording under the screen, further promote display screen display effect, the terminal intelligence is higher.

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.

An embodiment of the present application provides a display screen, and fig. 7 is a schematic view of a composition structure of the display screen provided in the embodiment of the present application, as shown in fig. 7, in the embodiment of the present application, the display screen is composed of a first display area, a second display area, and a third display area.

Specifically, in the embodiment of the present application, the position of the second display area is set with the position of the camera as a center, and the third display area is located between the first display area and the second display area; and the pixel density of the third display area is less than that of the first display area.

Further, in the embodiment of the present application, the pixel is disposed at the first position of the third display region, and the MUX circuit is disposed at the second position of the third display region; wherein the first position and the second position are not coincident. Specifically, the first port of the MUX circuit is electrically connected to the circuit of each column of pixels in the second display region, and the second port of the MUX circuit is electrically connected to the circuit of each column of pixels in the target sub-region. The target sub-area is located above the second display area, and the target sub-area is a partial area in the first display area.

It should be noted that, in the embodiment of the present application, the Display screen may be a Light Emitting Diode (LED) Display screen, including an active matrix AMOLED Display and a passive PMOLED Display, or may be a Three Dimensional (3D) Display screen, or a Plasma Display Panel (PDP), and preferably, the Display may be an OLED Display, where an independent TFT is used to control the AMOLED Display of each pixel unit, and the application does not specifically limit the type of the Display screen.

In the embodiment of the present application, the second display area is disposed with the position of the camera as a center. Specifically, cover the display screen in the camera top, central point under the screen that the camera position corresponds to display screen second display area puts, and further, this camera can be leading camera, and the camera can carry out image acquisition through the light that the second display area transmission came in.

Specifically, in the embodiment of the present application, the position of the camera under the screen is not limited, that is, the second display area in the display screen supports flexible setting, and is not only set at the top of the display screen. Optionally, the second display area may be a corner area of the display screen, or may be a central position above the display screen, and the specific position is based on the setting mode of the camera; and the second display area can be arc-shaped or linear.

Furthermore, the display screen may include a plurality of second regions, and then a plurality of third display regions correspond between first display region and a plurality of second display regions, and in the embodiment of the present application, the number of second display regions and third display regions is based on the specific setting mode and the number of cameras below the display screen. The present application is not particularly limited.

It should be noted that, in the embodiment of the present application, the third display region is located between the first display region and the second display region, that is, the third display region corresponds to a transition region between the first display region and the second display region. Alternatively, the third display region may be at least one of an upper side, a left side, or a right side of the second display region. For example, the third display region is located in a partial region of the first display region above the second display region; the third display area may also be a partial area of the first display area located on the left and right sides of the second display area, which is not specifically limited in this application.

In the embodiment of the present application, the first display region is a region of the display screen except for the second display region and the third display region, where an area of the first display region is not only larger than an area of the second display region and an area of the third display region, but also larger than a sum of the areas of the second display region and the third display region. Specifically, the first display area is a main area for displaying a picture on the terminal, and the terminal always presents pictures and characters to a user through the first display area.

Exemplarily, fig. 8 is a schematic structural diagram of a display screen according to an embodiment of the present application, and as shown in fig. 8, the display screen includes a first display area, a second display area, and a third display area, the second display area is disposed in a non-top-mounted manner, and a portion of the first display area is still above the second display area. The camera is arranged below the second display area screen, the second display area is rectangular, the third display area is located between the first display area and the second display area, the three sides of the upper side, the left side and the right side of the second display area are specifically included, and the third display area is linear.

It should be noted that, in the embodiment of the present application, in order to improve the display screen transmittance of the second display region and increase the light incident amount of the camera, so that the camera under the screen can better perform image acquisition, the pixel density of the second display region is smaller than that of the first display region, that is, the high pixel PPI is disposed in the first display region of the display screen, and the low pixel PPI is disposed in the second display region of the display screen.

Further, in the embodiment of the present application, the third display area of the display screen, i.e., the transition area between the first display area and the second display area, is also a low pixel density area. Optionally, the pixel density of the second display area is the same as the pixel density of the third display area.

It can be understood that if a flexible arrangement of the off-screen camera is to be achieved, there is a problem that there may be a normal high pixel density first display region above the off-screen camera area, i.e., a low pixel density second display region is sandwiched between the upper and lower high pixel density first display regions. At present, in the related art, the data lines in the first display region located below the second display region need to maintain the original structure to pass through the second display region, and connect the circuits for separating the pixels of the first display region on both sides. Specifically, if each column of pixels corresponding to the first display area is located in the second display area, the data line needs to pass through the second display area and be electrically connected to the circuits of each column of pixels located in the first display area and the second display area; if each column corresponding to the first display area in the second display area has no pixels, the data lines still need to pass through the blank area in the second display area to connect the circuits of each column of pixels in the first display area located at the upper and lower sides of the second display area.

Although the routing mode of the data lines in the display screen can enable the position of the camera not to be limited to the position under the screen at the top end of the display screen, when each column of positions corresponding to the first display area in the second display area has no pixel, the routing mode that the data lines still need to pass through the hollow white area in the second display area enables the routing of the shooting area under the screen to be too much, and the diffraction of the routing is enhanced, so that the defect that the transmittance of the shooting area under the screen is reduced is caused. In order to overcome the above-mentioned drawbacks, the related art utilizes the characteristic that the MUX circuit can drive a higher resolution with fewer data lines. Specifically, an independent transition area is distributed between a first display area and a second display area of the display screen, and a MUX circuit is specially arranged, so that flexible arrangement of the camera under the screen and good transmittance of the camera area under the screen are achieved.

Exemplarily, fig. 9 is a schematic diagram of a setting of a MUX circuit in the related art, where a rectangle filled with gray scale represents a pixel, and a dashed square without filling represents a gap without the pixel, as shown in fig. 9, since an under-screen image capture region is designed to be non-vertex-to-vertex, a first display region with normal high pixel density exists above a second display region, and a transition region is disposed between the first display region and the second display region; specifically, the pixel density of the second display region is smaller than the pixel density of the first display region.

Specifically, as shown in fig. 9, a MUX circuit is disposed in the transition region of the display panel to electrically connect the circuits of the pixels in the first display region and the circuits of the pixels in the second display region, that is, by using the characteristics of the MUX circuit, one data line S1 of the second display region is matched with the MUX circuit to drive the two data lines S1 and S2 of the first display region, and one data line S3 of the second display region is matched with the MUX circuit to drive the two data lines S3 and S4 of the first display region, that is, when the under-screen image capturing region is disposed in a non-overhead manner, that is, a normal display region exists above the under-screen image capturing region, the data lines do not need to completely pass through the under-screen image capturing region, including the pixel positions and the blank regions, to electrically connect the circuits of the pixels in the high PPI normal display region on both sides, and only need to keep the data lines in each column with the pixels in the under-screen image capturing region, so as to drive the pixels of the normal display area above the under-screen image pickup area by using the "one-drive-many" characteristic of the MUX circuit. The position of the camera under the screen can be flexibly set, and the good transmittance of the camera area under the display screen is ensured

However, only the MUX circuit is separately allocated to a transition area in the display screen, which causes a waste of the display screen area due to the space occupied by the driving tube of the MUX circuit, and since the MUX circuit does not have the display function of the pixels, when an image is displayed through the full screen of the display screen, there is a problem that a black edge is displayed in the transition area where the MUX circuit is allocated, which affects the display effect.

Further, in the embodiment of the present application, as shown in fig. 7, the display screen may set a third display region having the same pixel density as the second display region between the first display region and the second display region, and set the pixel and the MUX circuit in the third display region at the same time. Specifically, the pixel is disposed at a first position in the third display region, and the MUX circuit is disposed at a second position which is not overlapped with the first position, wherein a first port of the MUX circuit is electrically connected to the circuit of each row of pixels in the second display region, and a second port of the MUX circuit is electrically connected to the target sub-region, i.e., each row of pixels in the first display region and at a position above the second display region. Like this, not only can utilize the characteristic of MUX circuit, realize many data lines in the first display area of a data line drive in the second display area, but guarantee good transmissivity under the screen and the nimble setting of camera under the screen, and because MUX circuit is placed in the third display area who is provided with the pixel, and be the position department that does not coincide with the pixel, consequently, image display still can be carried out in the third display area, thereby the defect of the demonstration black border that has overcome the display screen and exists, promote the display effect of display screen.

Optionally, in an embodiment of the present application, in the display screen, the first display area sets a plurality of first pixels according to a first pixel density, the second display area sets a plurality of second pixels according to a second pixel density smaller than the first pixel density, and the third display area sets a plurality of third pixels according to a second pixel density same as that of the second display area.

Further, in the embodiments of the present application, the sizes of the first pixel, the second pixel and the third pixel may be the same, or the sizes of the second pixel and the first pixel may be the same and smaller than the third pixel; the first pixel and the third pixel may have the same size and are larger than the second pixel. Further, the shape of the first pixel, the second pixel, and the third pixel may be any one of regular patterns such as a rectangle, a square, a circle, and an ellipse, which is not specifically limited in this application.

Further, in the embodiments of the present application, the display screen may implement pixel light emission through the TFT driving circuit, and the back of each pixel unit is provided with the corresponding TFT driving circuit to control the light emitting state of the pixel. Alternatively, the display screen may adopt a TFT driver circuit of 2T1C, and may also adopt a driver circuit of 7T 1C. In order to improve the transmittance of the lower image pickup area of the display screen, the TFT drive circuit can be placed in the third display area through reasonable layout wiring, so that the transmittance of the lower image pickup area of the display screen is not influenced, and the display effect of the display screen for effectively displaying the AA area is also not influenced.

Further, in the embodiment of the present application, in the display screen, since it is necessary to ensure a good transmittance of the second display area, preferably, the circuit of the pixel in the second display area is a wire made of a transparent metal material, such as an Indium Tin Oxide (ITO) wire, and the material of the wires in the first display area and the second display area is not limited, and may be a metal wire or a transparent metal wire.

Optionally, in an embodiment of the present application, a composition structure of each pixel unit in the display screen may be an RGB structure, a bayer RGBG structure, or a Pentile RGB structure, which is not specifically limited in the present application.

In the embodiment of the present application, the first pixel in the first display area is always in an operating state, and is used for displaying a color picture and a black-and-white picture; and the working state of the second pixel in the second display area and the third pixel in the third display area is determined according to the working state of an under-screen sensing device, such as a front camera.

Specifically, when the lower screen camera is turned on to collect images, the pixels in the second display area and the third display area are both in an off state and do not emit light, that is, the second display area and the third display area do not display images; at this time, the display screen mainly performs image display through the first display region. When the camera is in a closed state, each pixel in the second display area and each pixel in the third display area work normally to emit light, and at the moment, the terminal displays pictures or characters through the first display area, the second display area and the third display area of the display screen, namely the full screen.

The embodiment of the application provides a display screen, which consists of a first display area, a second display area and a third display area, wherein the second display area is arranged by taking the position of a camera as the center, and the third display area is positioned between the first display area and the second display area; the pixel density of the third display area is less than that of the first display area; setting pixels at a first position of a third display area, and setting a MUX circuit at a second position of the third display area; wherein the first position and the second position are not coincident; the first port in the MUX circuit is electrically connected with the circuit of each column of pixels in the second display area, the second port in the MUX circuit is electrically connected with the circuit of each column of pixels in the target sub-area, and the target sub-area is located in the first display area and above the second display area. That is to say, in the embodiments of the present application, in the third display region between the first display region and the second display region of the display screen and having a low pixel density, the pixel and the MUX circuit are simultaneously disposed, so that when the under-screen image pickup region is in a non-top-mount arrangement, the MUX circuit can be used to realize control over the pixels in the partial region of the first display region located above the second display region without increasing the routing of the second display region; meanwhile, the MUX circuit is located in the third display area and is not overlapped with the pixels, and the display effect of the display screen can be further guaranteed. It is thus clear that the display screen that this application provided can realize simultaneously the nimble setting of camera position under the screen to and the regional good transmissivity of making a video recording under the screen, further promote display screen display effect, the terminal intelligence is higher.

Further, based on the above embodiment, in another embodiment of the present application, the first display area is provided with M columns of pixels, and the target sub-area is provided with N columns of pixels; wherein M is an integer greater than 1, and N is a positive integer multiple of M.

Specifically, in the embodiment of the present application, a plurality of transistors may be disposed in the MUX circuit, and the number of the transistors is set according to the number of pixel columns located in the target sub-area. If there are N columns of pixels in the target sub-area, the number of transistors in the MUX circuit is N, i.e., the number of transistors corresponds to the number of columns of pixels in the target sub-area.

Specifically, each transistor includes a first pole and a second pole, and the first poles of a plurality of N transistors may be collectively used as the first port, while each of the second poles of the N transistors may be used as the second port.

More specifically, the N second poles of the N transistors are electrically connected to the N circuits of the N columns of pixels in the target sub-area, respectively, that is, the second pole of each transistor is electrically connected to the circuit of each column of pixels in the target sub-area, so that the second port in the MUX circuit is electrically connected to the circuit of each column of pixels in the target sub-area.

In the embodiment of the present application, the number of the first poles of the transistors constituting the first port is determined according to the number of pixel columns in the target sub-area and the number of pixel columns in the second display area, that is, according to the ratio of N to M.

Specifically, if the calculated ratio of N to M is S, then S first poles of each S adjacent transistors of the N transistors are electrically connected to the circuits of a column of pixels in the second display region; wherein S is an integer less than N. For example, if the ratio of N to M is 2, then 2 first poles of each 2 adjacent ones of the N transistors are electrically connected to the circuitry of a column of pixels in the second display region.

More specifically, the MUX circuit in the display screen includes a plurality of MUX sub-circuits, the number of the MUX sub-circuits is determined according to the number of pixel columns in the second display area, and when M columns of pixels exist in the second display area of the display screen, the number of the corresponding MUX sub-circuits is also M. The number of transistors included in each MUX sub-circuit is determined according to a ratio of N to M, for example, the ratio of N to M is 2, each MUX sub-circuit includes 2 adjacent transistors, two first poles of the 2 transistors are electrically connected to the pixel circuits in one column of the second display region, and two second poles of the 2 transistors are electrically connected to the circuits of each column of pixels in the target sub-region.

It can be seen that the circuitry for a column of pixels in the second display area, and the circuitry for the adjacent S columns of pixels in the target sub-area, may form a path through the MUX sub-circuit. Specifically, a path is formed through a first port and a second port in the MUX sub-circuit.

Optionally, in the embodiment of the present application, a third display area with a low pixel density may be disposed above the second display area; third display regions with low pixel density may be disposed on both sides of the second display region.

For example, fig. 10A is a schematic diagram of a first setup of the MUX circuit according to the embodiment of the present application, in which a gray-filled rectangle represents a pixel, and a non-filled dotted square box represents a non-pixel gap, as shown in fig. 10A, a target sub-region with a normal high pixel density exists above a second display region, and a third display region is disposed above the second display region.

For example, fig. 10B is a schematic diagram of a setting of the MUX circuit according to the embodiment of the present application, where a rectangle filled with gray scale represents a pixel, and a dashed square without filling represents a gap without the pixel, as shown in fig. 10B, a first display region with normal high pixel density exists above the second display region, and a third display region is disposed above the second display region.

Specifically, in fig. 10A and 10B, the third display region is provided with both pixels and MUX circuits, and since there are only two columns of pixels in the second display region, the third display region is provided with two MUX sub-circuits (MUX sub-circuit 21 and MUX sub-circuit 22). The MUX sub-circuit 21 and the MUX sub-circuit 22 are respectively disposed at positions not overlapping with the pixels. There are 4 columns of pixels corresponding to the four data lines S1, S2, S3 and S4, respectively, and the second display area of low pixel density includes 2 columns of pixels with pixels only in the odd-numbered columns, so that the data lines S2 and S4 of the even-numbered columns are discarded and only two data lines, S1 and S3, corresponding to the pixels of the odd-numbered columns, are reserved. Further, since the ratio of the target sub-region to the number of pixel columns in the second display region is 2, the MUX sub-circuit 21 and the MUX circuit sub-circuit 22 respectively include two transistors, the first poles J1 of the two transistors Q1 and Q2 in the MUX sub-circuit 21 are commonly connected to the second display region data line S1, and the second pole J2 is respectively connected to the S1 and S2 data lines in the first display region; the first poles J1 of the two transistors Q3 and Q4 in the MUX sub-circuit 22 are commonly connected to the second display region data line S3, and the second poles J2 are respectively connected to the S3 and S4 data lines adjacent to the first display region.

Therefore, by utilizing the characteristics of the MUX circuit, one data line in the second display area drives a plurality of data lines in the first display area, the good transmittance under the screen and the flexible setting of the camera under the screen are ensured, and the MUX circuit is placed in the third display area provided with the pixels and is not overlapped with the pixels, so that the third display area can still display images, the defect of displaying black edges of the display screen is overcome, and the display effect of the display screen is improved.

Specifically, the first display area is a main area where the terminal performs image display, namely an AA area in the display screen, and the terminal always presents pictures and characters to the user through the first display area. It should be noted that, in the embodiment of the present application, in order to improve the display screen transmittance of the second display region and increase the light incident amount of the camera, so that the camera under the screen can better perform image acquisition, the pixel density of the second display region is smaller than that of the first display region, that is, the high pixel PPI is disposed in the first display region of the display screen, and the low pixel PPI is disposed in the second display region of the display screen.

In the embodiment of the present application, the number of the first poles of the transistors constituting the first port is determined according to the number of pixel columns in the target sub-area and the number of pixel columns in the second display area, that is, according to the ratio of N to M. Specifically, if the calculated ratio of N to M is S, then S first poles of each S adjacent transistors of the N transistors are electrically connected to the circuits of a column of pixels in the second display region; wherein S is an integer less than N. For example, if the ratio of N to M is 2, then 2 first poles of each 2 adjacent ones of the N transistors are electrically connected to the circuitry of a column of pixels in the second display region.
