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) Opening ratio: the ratio of the area of the light passing portion excluding the wiring portion and the transistor portion (normally hidden by a black matrix) for each sub-pixel to the area of the entire sub-pixel. The higher the aperture ratio, the higher the efficiency of light passing.

4) 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.

Specifically, the AMOLED display panel may be decomposed into the following components: (1) the glass panel Windows mainly plays a role of protecting a screen panel, and the transmittance is over 95 percent; (2) optical Clear Adhesive (OCA) for cementing the special Adhesive of the transparent optical element, wherein the transmittance is more than 95%; (3) a glass Touch panel (TSP) having a transmittance of 90% or more but generating light diffraction; (4) a polarizer Pol mainly functioning to prevent reflection of screen light; (5) the main structure of light emission, Encap; (6) a Thin Film Transistor (TFT) driver circuit Ltps; (7) substrate Cushion.

Further, the AMOLED display screen includes two structures of bottom emission and Top emission, fig. 1A is a view of an AMOLED bottom emission structure in the related art, and fig. 1B is a schematic view of an AMOLED Top emission structure in the related art. As shown in fig. 1A, in the bottom emission structure, a metal cathode and a transparent anode are used, a light emitting element is located at the end of the metal cathode, and light emitted by the light emitting element passes through the transparent anode and a TFT pixel driving circuit, thereby realizing image display on a display screen. As shown in fig. 1B, in the top emission structure, the light emitting element is located at the metal anode end, and light emitted from the light emitting element passes through the transparent cathode, the buffer layer, and the transparent panel, thereby implementing image display on the display screen. Table 1 shows a comparison relationship between two light emitting structures of the AMOLED display screen.

TABLE 1

	Bottom emission	Top-emitting light
			Resolution ratio	＜180dpi	＞200dpi
Color saturation	About 70% (NTSC)	Greater than 100% (NTSC)
			Luminous efficiency	Is low in	Height of
Purity of luminescence	Is low in	Height of
			Brightness of light	Is low in	Height of
Color gamut	Small	Big (a)
			Angle of view	Big (a)	Small
Driving voltage	Height of	Is low in
			Life span	Is relatively short	Is relatively long

As can be seen from table 1, in the AMOLED light emitting structure, the bottom light emitting structure has a mature technical process, a small selection risk, or even no risk, and in the top light emitting structure, there are two difficulties of cathode fabrication and encapsulation at present, but light emitted by the light emitting component in the top light emitting structure is not blocked by the driving circuit, and compared with the bottom light emitting structure, the bottom light emitting structure has a higher aperture ratio, so that the top light emitting structure has a greater advantage in high-resolution applications.

The manufacturing process of the AMOLED display screen is mainly divided into three processes of a back plate section, a front plate section and a module section. The back plate section process forms a Low Temperature Polysilicon (LTPS) driving circuit by film forming, exposure and etching of different films with different patterns and different materials, and the LTPS driving circuit provides a lighting signal and stable power supply input for a light-emitting device; in the front plate section process, materials such as organic luminescent materials, cathodes and the like are evaporated on a back plate through a high-precision Metal Mask (FMM), and are combined with a driving circuit to form a luminescent device, and then the luminescent device is packaged in an oxygen-free environment to play a role in protection; and cutting the packaged panel into the size of an actual product by the module section process, then performing various processes such as polaroid attachment, circuit control and chip attachment, aging test and product packaging, and finally presenting the product in the hands of a customer.

Further, fig. 2 is a schematic diagram of a stacked structure of an AMOLED display screen In the related art, as shown In fig. 2, a display panel employs Thin-Film Encapsulation (TFE), and the display panel is composed of a plurality of pixel units, each pixel unit includes a cathode, an organic light emitting component, an anode, and a TFT driving circuit, wherein (1) the cathode is generally formed by combining metals or alloys, such as Ag, Al, Mg, In, Li, and Ca, and can be used as a cathode material. The ideal cathode is to use a low work function metal as the electron injection layer and a stable metal with high work function (such as Mg/AgLi/Al) as the passivation layer. (2) The anode is mostly the auxiliary electrode wiring material, and since the OLED is a current driving component, when the external circuit is too long or too thin, a severe voltage gradient will be generated in the external circuit, so that the voltage actually falling on the OLED component is reduced, and the luminous intensity of the panel is reduced, therefore, the cathode wiring material is usually Cr/Al/Cr or Mo/Al/Mo. (3) The driving TFT is generally manufactured by LTPS process, which is usually a silicon-based material, and is an opaque material, and mainly used to control the light emitting element to emit light.

Further, at present, two driving circuit structures of a TFT circuit of 2T1C and a TFT circuit of 7T1C are commonly used for a pixel driving circuit.

Exemplarily, fig. 3 is a schematic diagram of a 2T1C driving circuit in the related art, as shown in fig. 3, the TFT driving circuit of 2T1C includes a storage capacitor C1, a driving TFT (T2), a switching TFT (T1), an OLED, and various layout traces, and its operation principle is as follows: when the scanning line is selected, the switch TFT is started, data (voltage) of the data line charges the storage capacitor through the switch TFT, and the voltage of the storage capacitor controls the drain current of the driving TFT and is used for supplying power to the OLED; when the scanning line is not selected, the switch TFT is cut off, the electric charge stored on the storage capacitor continuously maintains the grid voltage of the driving TFT, the driving TFT keeps the conducting state, and the OLED is continuously supplied with power. Therefore, the OLED is in constant current control throughout the frame period.

Exemplarily, fig. 4 is a schematic diagram of a 7T1C driving circuit in the related art, as shown in fig. 4, 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 the TFT3 is low, T2 and T3 are turned on, the drain and gate of T1 are shorted, and 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.

With the development of scientific technology, the updating speed of the mobile phone is faster and faster, and the screen ratio becomes an important standard of product differentiation at present, so that the mobile phone is promoted to develop towards the direction of a full screen. However, the configuration of the front camera of the mobile phone directly affects the development of the full screen, and the front camera of the mobile phone needs to be hidden if the full screen of the terminal is to be realized. At present, the mode of generally adopting the integrated leading camera under the screen, be about to the camera hides in the display screen back.

In order to achieve a better under-screen shooting effect, two schemes are often adopted in the related art to achieve high-transmittance under-screen camera image acquisition. One is to improve the light transmittance of the front camera area by adopting a mode of reducing PPI in a local area; and the other is to replace the anode material of the display screen with a transparent material so as to improve the light transmittance of the local area of the display screen.

Specifically, fig. 5A is a schematic view illustrating the effect of transmittance of a display screen panel in the related art, as shown in fig. 5A, the display screen includes a normal display region and a local display region where a camera is disposed under the display screen, the display screen employs Thin-film encapsulation (TFE), each pixel unit includes a cathode, an organic light emitting component, and an anode, wherein the transmittance of the cathode is about 50%, and the anode is made of an opaque material, and as can be seen from fig. 5A, the intensity of transmitted light after external light/ambient light passes through the screen panel at the normal display region with high pixel PPI is smaller than the intensity of transmitted light after passing through the screen panel at the local display region with low pixel PPI; that is, the transmittance of the display screen at the normal display region of the high pixel PPI is less than the transmittance at the local display region of the low pixel PPI.

Specifically, fig. 5B is a schematic diagram illustrating the effect of transmittance of a display screen panel in the related art, as shown in fig. 5B, the display screen includes a normal display area and a local display area under the screen, where a camera is disposed, each pixel unit includes a cathode, an organic light emitting component and an anode, and the anode and the cathode in the local display area are made of transparent materials; for example, as shown in fig. 5B, the intensity of the transmitted light of the external light/ambient light after passing through the screen panel in the normal display area is smaller than the intensity of the transmitted light after passing through the screen panel in the local display area where the cathode/anode is made of the transparent material; i.e. the transmittance at the normal display area of the display screen is smaller than the transmittance at the partial display area of the transparent cathode/anode.

However, although the manner of reducing the PPI in the local area increases the aperture ratio of the display screen panel, increases the transmittance of the display panel, and enables more light to be collected by the camera under the screen through the local display area, the reduction of the difference in pixel density of the display screen caused by the PPI in the local display area may cause the luminance and the smoothness of display of the high PPI normal display area and the low PPI local area of the display screen to have obvious differences, including obvious luminance difference and boundary sense, and reduce the display effect of the display 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 between the first display area with high pixel density and the second display area with low pixel density of the display screen and having the same low pixel density with the second display area, a plurality of size parameters are set to be larger than third pixels of second pixels in the first display area and the second display area, so that the luminance of the pixels in the third display area is between the luminance of the pixels in the first display area and the luminance of the pixels in the second display area, the obvious luminance difference between the first display area and the second display area caused by pixel density difference can be relieved, the boundary feeling is reduced, the display effect of the display screen is improved, and 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. 6 is a schematic view of a composition structure of the display screen provided in the embodiment of the present application, as shown in fig. 6, 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.

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.

Note that, in the embodiment of the present application, the second display region and the third display region are provided centering on the position of the sensor device. Specifically, the display screen covers the sensing device, the position of the sensing device corresponds to the central position under the display screen of the second display area and the third display area of the display screen, and optionally, the sensing device can be a camera for taking a picture in a front-mounted manner; the light sensor can also be used for detecting the intensity and chromaticity of the external light.

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. In addition, the first display area is an area of the display screen except the second display area and the third display area.

Optionally, in an embodiment of the present application, the second display area may be a corner area of the display screen, or may also be a center position of an edge above or below the display screen, where a specific position is based on a setting manner of the sensing device; and the third display region may be arc-shaped or linear.

Further, the display screen may include a plurality of second regions, and then a plurality of third display regions correspond between the first display region and the plurality of second display regions, in an embodiment of the present application, the number of the second display regions and the number of the third display regions are based on the specific arrangement manner and the number of the sensor devices below the display screen. The present application is not particularly limited.

For example, fig. 7A and 7B are a first schematic view and a second schematic view of a display screen according to an embodiment of the present disclosure, as shown in fig. 7A, a camera is disposed below the display screen, and a third display region between a first display region and a second display region is linearly disposed corresponding to a middle position above the display screen, as shown in fig. 7B, two camera modules of the first camera and the second camera are disposed below the display screen and respectively correspond to left and right corner positions above the display screen, that is, the display screen has two second display regions, where the two third display regions between the two second display regions and the first display region are arc-shaped.

Further, in the embodiment of the present application, the area of the first display region is not only larger than both the area of the second display region and the area of the third display region, but also larger than the 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 is used for presenting pictures and characters to a user.

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

Specifically, in the embodiment of the present application, in the display panel, the first display region sets a plurality of first pixels at a first pixel density, the second display region sets a plurality of second pixels at a second pixel density smaller than the first pixel density, and the third display region sets a plurality of third pixels at the same second pixel density as the second display region.

Optionally, in an embodiment of the present application, 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. Specifically, the driving circuit includes a plurality of TFTs, and the functions of the TFTs are different from each other. In order to improve the aperture ratio of the pixels of the display screen, the TFT used for driving in the TFT driving circuit can be placed on the back of the light-emitting component of each pixel unit through reasonable layout wiring, and the TFT used for resetting and controlling functions can be placed at a position far away from the light-emitting component.

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.

It should be noted that, in the embodiment of the present application, the size parameter corresponding to the third pixel is greater than the size parameter of the first pixel, and meanwhile, the size parameter corresponding to the third pixel is also greater than the size parameter corresponding to the second pixel. That is, the third pixel is the largest area pixel in the display panel.

It can be understood that if 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, although the transmittance of the display screen in the second display region is increased to enable the camera under the screen to better capture images, when images are displayed through the second display region, the difference of the pixel PPI may cause a significant brightness difference between the first display region and the second display region, the edge sense is enhanced, and the characteristic of the pixel luminous intensity is improved based on the increase of the pixel area, in the display screen of the present application, a plurality of first pixels are disposed between the first display region of the high pixel PPI and the second display region of the low pixel PPI, and the third display region has the same low pixel PPI as the second display region, so that the luminous intensity of the pixels in the third display region is between the luminous intensity of the first display region and the luminous intensity of the pixels in the second display region, the display screen can effectively relieve the obvious boundary sense and brightness difference sense between the first display area and the second display area, and realize the balance of image display of the display screen.

The embodiment of the application provides a display screen, which is composed of a first display area, a second display area and a third display area, wherein the second display area and the third display area are arranged by taking the position of a sensing device as the center, and the third display area is positioned between the first display area and the second display area; the first display area is provided with a plurality of first pixels according to a first pixel density; the second display area is provided with a plurality of second pixels according to a second pixel density; the third display area is provided with a plurality of third pixels according to a second pixel density; wherein the first pixel density is greater than the second pixel density; the size parameter corresponding to the third pixel is larger than that corresponding to the first pixel, and the size parameter corresponding to the third pixel is larger than that corresponding to the second pixel. That is to say, in the embodiment of the present application, in a third display area between the first display area with high pixel density and the second display area with low pixel density of the display screen and having the same low pixel density as the second display area, a plurality of size parameters are set to be larger than third pixels of the first pixels in the first display area and the second pixels in the second display area, so that the light emission luminance of the pixels in the third display area can be between the light emission luminance of the pixels in the first display area and the light emission luminance of the pixels in the second display area, and further, the obvious luminance difference between the first display area and the second display area due to the difference in pixel density can be alleviated, the boundary feeling is reduced, thereby the display effect of the display screen is improved, and the terminal intelligence is higher.

Based on the above embodiment, in another embodiment of the present application, a specific arrangement manner of pixels in the first display area, the second display area, and the third display area of the display screen may be as follows:

in an embodiment of the present application, in a display screen, a first display region sets a plurality of first pixels at a first pixel density; the second display area is provided with a plurality of second pixels according to a second pixel density; the third display area sets a plurality of third pixels in accordance with a second pixel density.

Specifically, the first pixel density is greater than the second pixel density.

Specifically, the size parameter corresponding to the third pixel is larger than the size parameter corresponding to the first pixel and larger than the size parameter corresponding to the second pixel.

Specifically, in the embodiment of the present application, the light transmittance of the second display region can be adjusted only by reducing the pixel density, that is, the size of the pixel is not changed, and the size parameter corresponding to the first pixel is always equal to the size parameter corresponding to the second pixel.

Specifically, in the embodiment of the present application, in order to make the camera have better light transmittance, the pixel density may be changed, and the pixel size may also be changed at the same time, that is, not only the first pixel density is greater than the second pixel density, but also the second pixel in the second display area is smaller than the first pixel in the first display area.

For example, fig. 8A is a schematic diagram of a pixel layout of a display panel according to an embodiment of the present application, where a square filled rectangle is used to represent a third pixel, and a left oblique line filled rectangle is used to represent a first pixel and a second pixel. As shown in fig. 8A, the third display region of the display panel is provided with a plurality of third pixels having the largest area, and the first display region and the second display region are provided with a plurality of first pixels and second pixels having the same size and smaller than the third pixels.

For example, fig. 8B is a schematic diagram of a pixel layout of a display panel according to an embodiment of the present application, where a square filled rectangle is used to represent a third pixel, a left oblique line filled rectangle is used to represent a first pixel, and a right oblique line filled rectangle is used to represent a second pixel. As shown in fig. 8B, the third display region of the display panel is provided with a plurality of third pixels having the largest area, the first display region is provided with a plurality of first pixels having an intermediate area size, and the second display region is provided with a plurality of second pixels having the smallest area.

Further, in the embodiment of the present application, since the first pixel density is greater than the second pixel density, that is, the number of pixels included in the unit area of the first display region is greater than the number of pixels included in the unit area of the second display region, the distance between two adjacent first pixels in the first display region is smaller than the distance between two adjacent second pixels in the second display region.

Optionally, in the embodiment of the present application, the display screen may keep a vertical distance between two adjacent pixels unchanged, and reduce the pixel density of the second display region by changing pixels arranged in a horizontal direction per unit area, that is, a horizontal distance between two adjacent first pixels in the first display region is smaller than a horizontal distance between two adjacent second pixels in the second display region.

For example, fig. 9A is a schematic diagram of a distance between adjacent pixels in a display panel according to an embodiment of the present application, where a first pixel and a second pixel are represented by a rectangle filled with left oblique lines, as shown in fig. 9A, the first pixel and the second pixel have the same size, and since the pixel density of the first display region is greater than that of the second display region, a horizontal distance X1 between two adjacent first pixels in the first display region is smaller than a horizontal distance X2 between two adjacent second pixels in the second display region.
