Description of the embodiments

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 for purposes of illustration only and are not intended to be limiting. It should be noted that, for convenience of description, only a portion related to the related application is shown in the drawings.

Before describing embodiments of the present invention in further detail, the terms and terminology involved in the embodiments of the present invention will be described, and the terms and terminology involved in the embodiments of the present invention will be used in the following explanation.

1) A pixel: an indivisible unit or element in the whole image; the image is formed of small blocks of pixels, each of which has a definite position and assigned color value, the color and position of which determine the appearance of the image.

2) Pixel density (Pixels Per Inch, PPI): density units of pixels, expressed as the number of pixels per inch; the higher the PPI value, the higher the density the display screen can display the image, and the more the details of the picture will be.

3) Active-matrix organic light emitting diode (AMOLED) display screen: the organic thin film material is used between the anode and the cathode for a series of time, so that the effect of light emission is achieved. AMOLED needs to rely on TFT to emit various colors after adjusting the ratio of the three primary colors of the pixel.

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

For example, fig. 1 is a schematic diagram of a related art 2T1C driving circuit, and as shown in fig. 1, the TFT driving circuit of 2T1C includes a storage capacitor C1, a driving TFT, T1, a switching TFT, T2, an OLED, and various layout wires, and the working principle thereof is as follows: when the scanning line is selected, T2 is started, the data line data (voltage) charges the storage capacitor through T2, and the voltage of the storage capacitor controls the drain current of the drive T1 and is used for supplying power to the OLED; when the scan line is not selected, the switch T2 is turned off, the charge stored on the storage capacitor continues to maintain the gate voltage of the drive T1, and the drive T1 remains on to continue to supply power to the OLED. Thus, the OLED is in constant current control throughout the frame period.

For example, 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, including a storage capacitor C1, three driving TFTs including T1, T5, and T6, four reset and control TFTs including T2, T3, T4, and T7, an OLED, and various layout wirings, specifically, the basic operation principle includes three operation phases of capacitor discharge, compensation, and OLED light emission, when in the capacitor discharge phase, the storage capacitor C1 is at a low potential, the T4 is turned on, the drain electrode of the T4 is at a low potential, and the capacitor C1 is discharged; when in the compensation stage, the source electrode of the T3 is at a low potential, the T2 and the T3 are conducted, the drain electrode and the grid electrode of the T1 are short-circuited, vg > Vth, and the T1 is opened until Vg=Vdata-Vth; when in the OLED light emitting phase, the sources of T5 and T6 are low, T5 and T6 are on, vgs=ELVDD- (Vdata-Vth).

Further, compared with the 7T1C TFT circuit, the 2T1C circuit has a problem that Vth dispersion of the TFT tube cannot be eliminated, resulting in uneven brightness of the screen, so that the current circuit mostly adopts the 7T1C TFT circuit.

A multi-division signal output selector (MUX) circuit: the signal used to select the desired output is typically used to switch the output of the Data signal. Wherein the MUX circuit is near the IC at the lower end of the screen, with the goal of using the IC to drive higher resolution using fewer data Source lines, such as 1: the 2MUX reads that 1 data line cooperates with MUX circuit to drive 2 lines. The prior proposal is 1: 2. 1: 3. 1:6, etc., the watch uses 1:12.

for example, fig. 3 is a schematic structural diagram of a display screen in the related art, and 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 area, and further, the display screen 10 includes a MUX circuit 13 below the display area, and a display driving chip (display driver integrated circuit, DDIC) 14 electrically connected to the MUX circuit 13.

Specifically, fig. 4 is a schematic diagram of the working principle of the MUX circuit in the related art, G is a green sub-pixel unit, R is a red sub-pixel unit, B is a blue sub-pixel unit, and as shown in fig. 4, the working principle of the MUX circuit 13 is as follows: two data signals need to be switched in the driving time of one row, if a green picture needs to be displayed and a Scan (n) row is scanned, a first half section G port on which the signals are opened is opened first, and a first MUX circuit and a second MUX circuit output gray scale signals corresponding to the green picture so as to drive a sub-pixel G; and when the R/B port is opened in the second half section of the signal, the first MUX circuit and the second MUX circuit both input 0 gray scale signal, so that the R/B sub-pixel is ensured not to emit light.

If a red picture is required to be displayed, scanning the line of Scan (n), opening a first half section G port with a signal opened, and outputting 0 gray scale signals by a first MUX circuit and a second MUX circuit; when the second half section of the signal is reached, the R/B port is opened, the first MUX circuit inputs a 0 gray scale signal, and the B sub-pixels of the corresponding column are ensured not to emit light; meanwhile, the second MUX circuit inputs a red gray scale signal to enable red sub-pixels of the corresponding columns to start to emit light; when Scan (n+1) is scanned, the line is similar, but the gray scale signals output from the first MUX circuit and the second MUX circuit are alternated, so that a red picture can be displayed. Further, displaying a blue picture is similar in principle to displaying a red picture, except that the gray scale signals output from the first MUX circuit and the second MUX circuit alternate.

Specifically, fig. 5A is a schematic diagram of a position of an under-screen image capturing area in the related art, as shown in fig. 5A, a display screen includes a normal display area with high PPI and a local display area (under-screen image capturing area) with a camera arranged under the screen with low PPI, and the under-screen image capturing area is arranged by sticking a top, that is, the under-screen image capturing area is closely attached to the top of the display screen; fig. 5B is a schematic diagram of a second position of an under-screen image capturing area in a display screen in the related art, as shown in fig. 5B, where the display screen includes a normal display area and an under-screen image capturing area, and the under-screen image capturing area is set by non-sticking, that is, in the display screen, the upper end of the under-screen image capturing area has a normal display area with high pixel density.

Further, based on fig. 5A and 5B, fig. 6A and 6B are respectively a first schematic diagram and a second schematic diagram of the wiring of the under-screen image capturing area in the related art, the gray-scale filled rectangle represents the pixel, the unfilled dotted square represents the pixel-free gap, as shown in fig. 6A, when the under-screen image capturing area adopts the top-mounted arrangement as shown in fig. 5A, since the under-screen image capturing area is a low pixel density area and there is no normal display area with high pixel density above the image capturing area, the data lines in the normal display area below the under-screen image capturing area need not all pass through the under-screen image capturing area, but only remain the data lines at the position where the under-screen image capturing area has pixels, that is, discard the data lines S1 and S3 at the position where the under-screen image capturing area has pixels, and discard S2 and S4 directly. As shown in fig. 6B, when the under-screen image capturing area is set by using the non-top-mounting arrangement as shown in fig. 5B, although the under-screen image capturing area is a low pixel density area, since there is a normal display area with a high pixel density 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 all keep the original structure to pass through the under-screen image capturing area, and connect each column of pixel circuits located on the upper and lower sides of the under-screen image capturing area and in the normal display area. It can be seen that in fig. 6B, the four data lines S1, S2, S3, and S4 remain in the under-screen image capturing area.

Therefore, the sticking top setting has the effects of reducing wiring diffraction and improving the transmittance of the shooting area, but the sticking top setting of the under-screen shooting area has the problems of limiting the position of the under-screen camera and poor display effect of the UI status bar; correspondingly, the non-top-attaching arrangement of the under-screen image pickup area can enable the camera to be arranged at any position under the screen, and the UI status bar has good display effect, so that the problem existing in the top-attaching arrangement can be solved by the non-top-attaching design of the under-screen image pickup area, but when the non-top-attaching arrangement is carried out, the wiring of the under-screen image pickup area is increased, the wiring diffraction is enhanced, and the defect of lower transmittance of the under-screen image pickup area is caused. Therefore, a display screen is urgently needed, the position of an under-screen camera is not limited, and good transmittance of an under-screen camera shooting area can be ensured.

In order to solve the problems existing in 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 between the first display area and the second display area of the display screen and having a low pixel density, pixels and a MUX circuit are simultaneously arranged, so that when the under-screen image pickup area is arranged in a non-top-mounted manner, the MUX circuit can be utilized to realize the control of the pixels in a partial area of the first display area above the second display area without increasing the wiring of the second display area; meanwhile, the MUX circuit is positioned at a position which is not overlapped with the pixels in the third display area, so that the display effect of the display screen can be further ensured. Therefore, the display screen that this application provided can realize the nimble setting of camera position under the screen simultaneously to and the regional good transmissivity of making a video recording under the screen, further promotes the display screen display effect, and 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 diagram of a composition structure of the display screen according to the embodiment of the present application, as shown in fig. 7, in the embodiment of the present application, the display screen is formed by 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 the center, and the third display area is located between the first display area and the second display area; wherein the pixel density of the third display area is less than the pixel density of the first display area.

Further, in the embodiment of the present application, a pixel is disposed at a first position of the third display area, and a MUX circuit is disposed at a second position of the third display area; wherein the first position and the second position are misaligned. Specifically, a first port in the MUX circuit is electrically connected to the circuitry of each column of pixels in the second display region, and a second port in the MUX circuit is electrically connected to the circuitry of each column of pixels in the target subregion. The target subarea is located above the second display area, and the target subarea 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 (light emitting diode, LED) display screen, including an active matrix AMOLED display and a passive PMOLED display, or may be a three-dimensional (Three Dimensional, 3D) display screen, or a plasma display (Plasma Display Panel, PDP) display, etc., preferably, the display may be an OLED display, and the type of the display screen is not specifically limited by the application, where an individual TFT is used to control the AMOLED display of each pixel unit.

In the embodiment of the present application, the second display area is set with the position of the camera as the center. Specifically, the display screen is covered above the camera, the position of the camera corresponds to the center position under the screen of the second display area of the display screen, further, the camera can be a front camera, and the camera can collect images by light transmitted in through the second display area.

Specifically, in the embodiment of the present application, the position of the under-screen camera is not limited, that is, the second display area in the display screen supports flexible setting, and is not only set at the top end 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, where the specific position is based on the setting mode of the camera; and the second display area may be arc-shaped or may be straight.

Further, the display screen may include a plurality of second display areas, and further, a plurality of third display areas correspond to each other between the first display area and the plurality of second display areas. The present application is not particularly limited.

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

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

Fig. 8 is a schematic structural diagram of a display screen according to an embodiment of the present application, where, as shown in fig. 8, the display screen includes a first display area, a second display area, and a third display area, where the second display area is set by non-sticking, and a part of the first display area is still above the second display area. The camera is arranged below the screen of the second display area, the second display area is rectangular, the third display area is positioned between the first display area and the second display area and specifically comprises three sides, namely the upper side, the left side and the right side of the second display area, and the third display area is linear.

It should be noted that, in the embodiment of the present application, in order to improve the transmittance of the display screen in the second display area, the light incoming amount of the camera is increased, so that the under-screen camera can perform image acquisition better, the pixel density of the second display area is smaller than that of the first display area, that is, the first display area of the display screen is provided with high pixels PPI, and the second display area is provided with low pixels PPI.

Further, in the embodiment of the present application, the third display area of the display screen, that is, 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 and the pixel density of the third display area are the same.

It will be appreciated that if flexible placement of the under-screen camera is to be achieved, there is a problem in that there may be a normally high pixel density first display area above the under-screen camera area, i.e. a low pixel density second display area is sandwiched between the upper and lower high pixel density first display areas. Currently, in the related art, the data lines in the first display area below the second display area are all required to pass through the second display area while maintaining the original structure, and are connected to the circuits for separating the pixels in the first display area. Specifically, if pixels are located at each column position corresponding to the first display area in the second display area, the data line needs to pass through the second display area and be electrically connected with the circuits of each column of pixels located in the first display area and the second display area; if there is no pixel in the second display area for each column corresponding to the first display area, the data line still needs 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 on the upper and lower sides of the second display area.

Although the above-mentioned routing manner of the data line in the display screen can make the position of the camera not limited to the position under the top screen of the display screen, when there is no pixel in the second display area and every column position corresponding to the first display area, the routing manner of the data line still needs to pass through the blank area in the second display area can make the routing of the under-screen camera area excessive, and enhance the routing diffraction, thereby resulting in the defect of reduced transmittance of the under-screen camera area. In order to overcome the above-mentioned drawbacks, the related art solves the above-mentioned problems by utilizing the characteristic that the MUX circuit can drive higher resolution using fewer data lines. Specifically, an independent transition region is allocated between a first display region and a second display region of the display screen, and a MUX circuit is specially arranged, so that flexible setting of an under-screen camera and good transmittance of the under-screen camera region are realized.

For example, fig. 9 is a schematic diagram illustrating the arrangement of a MUX circuit in the related art, where a gray-scale filled rectangle represents a pixel, and a non-filled dotted square represents a non-pixel void, as shown in fig. 9, since the under-screen image capturing area is of a non-top-mounted design, a first display area with a normal high pixel density exists above the second display area, and a transition area is arranged between the first display area and the second display area; specifically, the pixel density of the second display area is smaller than the pixel density of the first display area.

Specifically, as shown in fig. 9, a MUX circuit is disposed in the transition area of the display screen, so as to be electrically connected with the circuit of the pixels in the first display area and the circuit of the pixels in the second display area, that is, by using the characteristics of the MUX circuit, one data line S1 in the second display area is matched with the MUX circuit to drive the two data lines S1 and S2 in the first display area, and one data line S3 in the second display area is matched with the MUX circuit to drive the two data lines S3 and S4 in the first display area, that is, when the under-screen image capturing area is set by adopting a non-top-attaching mode, that is, there is a normal display area above the under-screen image capturing area, the data lines do not need to pass through the under-screen image capturing area with low PPI, including the pixel position and the blank area, so as to electrically connect the circuits of the pixels in the high PPI normal display area on the two sides, only need to keep the data lines located in each row with the pixels in the under-screen image capturing area, and drive the pixels in the normal display area above the under-screen by using the characteristic of the "one driving multiple" of the MUX circuit. The position of the camera under the support screen can be flexibly set, and good transmittance of the camera shooting area under the display screen is ensured.

However, only the MUX circuit is arranged in the display screen by independently distributing a transition area, the area of the display screen is wasted because the driving tube of the MUX circuit occupies space, and the MUX circuit does not have the display function of pixels, so that when the image is displayed through the full screen of the display screen, the problem of black display exists in the transition area of the MUX circuit, and the display effect is affected.

Further, in the embodiment of the present application, as shown in fig. 7, the display screen may provide a third display area having the same pixel density as the second display area between the first display area and the second display area, and simultaneously provide the pixels and the MUX circuits in the third display area. Specifically, the pixels are disposed at the first position of the third display area, and the MUX circuits are disposed at the second position which is not coincident with the first position, wherein the first port of the MUX circuits is electrically connected to the circuit of each column of pixels in the second display area, and the second port of the MUX circuits is electrically connected to the target sub-area, i.e., each column of pixel circuits located in the first display area and located above the second display area. Therefore, the characteristics of the MUX circuit can be utilized to drive a plurality of data lines in the first display area by one data line in the second display area, good transmittance under the screen and flexible setting of the camera under the screen are ensured, and the MUX circuit is arranged in the third display area provided with the pixels and at the position which is not overlapped with the pixels, so that the third display area can still display images, the defect of black display edge of the display screen is overcome, and the display effect of the display screen is improved.

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 identical to the second display area.

Further, in the embodiment 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 be the same size and larger than the second pixel. Further, the shapes of the first pixel, the second pixel and the third pixel may be any one of regular patterns such as rectangle, square, circle and ellipse, which is not particularly limited in this application.

Further, in the embodiment of the application, the display screen can realize pixel luminescence through the TFT driving circuit, and the back of each pixel unit is provided with a corresponding TFT driving circuit to control the luminescence state of the pixel. Alternatively, the display screen may use a 2T1C TFT driving circuit, or a 7T1C driving circuit. In order to improve the transmittance of the under-screen photographing area of the display screen, the TFT driving circuit can be placed in the third display area through reasonable layout wiring, so that the transmittance of the under-screen photographing area is not affected, and the display effect of the effective display AA area of the display screen is not affected.

Further, in the embodiment of the present application, in the display screen, because good transmittance of the second display area needs to be ensured, preferably, the circuit of the pixel in the second display area adopts a wire made of a transparent metal, such as an Indium Tin Oxide (ITO) wire, and the materials of the wires in the first display area and the second display area are not limited, and may be metal wires or transparent metal wires.

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

Specifically, when the under-screen camera is started to collect images, pixels in the second display area and the third display area are in an off state and do not emit light, namely the second display area and the third display area do not display images; at this time, the display screen mainly displays an image through the first display area. 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.

That is, in the embodiment 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 pixels and the MUX circuit are simultaneously provided so that when the under-screen image pickup region is a non-overhead setting, control of the pixels in the partial region of the first display region located above the second display region can be achieved without increasing the wiring of the second display region by using the MUX circuit; meanwhile, the MUX circuit is positioned at a position which is not overlapped with the pixels in the third display area, so that the display effect of the display screen can be further ensured.

For example, if the ratio of N to M is 2, 2 first poles of every 2 adjacent ones of the N transistors are electrically connected to the circuits of a column of pixels in the second display area.

More specifically, the MUX circuit in the display screen includes a plurality of MUX sub-circuits, where the number of MUX sub-circuits is determined according to the number of columns of pixels in the second display area, and when there are M columns of pixels in the second display area of the display screen, the number of corresponding MUX sub-circuits is also M.
