According to one embodiment of the present invention, a display screen is provided.
As shown in fig. 3, the display screen includes a display panel 305 and a polarizing layer 303 disposed above the display panel 305, the polarizing layer 303 including a plurality of polarizing plates thereon;
the display panel 305 includes at least one first region 305a and a second region, wherein the pixel density of the first region 305a is lower than that of the second region; a linear polarizing plate 303a is disposed on the polarizing layer 303 corresponding to the first region 305 a.
In this example, the pixel density on the display panel 305 is designed in a partition manner, for example, the display panel 305 includes two first regions 305 a; the remaining areas of the display panel 30 of the two first areas 305a are removed to form a second area.
In this example, the pixel density of the first region 305a is lower than that of the second region, so that the light transmittance of the first region 305a on the display panel 305 is higher than that of the second region; when the display panel is applied to electronic equipment, for example, a camera module is arranged below the first area 305a, external light can penetrate through the first area 305a to improve the light receiving amount and the imaging effect of the camera module, so that the function of the camera module is optimized; the pixel density of the second area is set to be the pixel density universal for the display panel, so that the granular sensation of the display screen is reduced, and the fidelity of the display image of the display screen is improved.
On the other hand, when the pixel density on the display panel 305 is designed in a partition manner, the pixel density of the first region 305a is lower than that of the second region, the linear polarizer 303a is arranged on the polarizing layer corresponding to the first region 305a, and the linear polarizer 303a can transmit the light rays of the external light rays in the same polarization direction as that of the linear polarizer 303a, so that the light transmittance of the display screen is improved, and the imaging effect of the camera module can be improved.
The embodiment of the invention overcomes the technical bias in the prior art. For example, in the prior art, the higher the pixel density of the display panel, the better, and at the same time, the external light is prevented from being able to penetrate through the display panel, so as to improve the fidelity of the display image of the display screen. However, the inventor finds that the problems that the camera module of the full-screen electronic device in the prior art receives less external light and has poor imaging quality can be solved by arranging the pixel density on the display panel in a partition mode and arranging the linear polarizer on the area with low pixel density under the condition that the simulation degree of the display image of the display screen is not influenced.
Optionally, the display screen of this example includes a cover plate layer 301, a polarization layer 303 bonded to the cover plate 301 with an optical adhesive 302; a display panel 305 located below the polarizing layer 303; a driving device 306 located below the display panel 305; and an elastic component located below the driving device 306, for example, the elastic component includes foam 307, and the elastic component is used for bearing the display screen on one hand and can play a role of buffering on the other hand.
The display panel 305 includes a first region and a second region, wherein a phase retarder 304 is disposed under the polarizing layer 303 opposite to the second region. For example, referring to fig. 3, the region a is a polarizing layer opposite to the first region 305a, and the phase retarder 304 is not disposed in the region a.
A linear polarizer is disposed on the polarization layer opposite to the second region, and a phase retarder 304 is disposed below the polarization layer 303 opposite to the second region, and the linear polarizer and the phase retarder 304 form a circular polarizer configured to shield external light and prevent the external light from transmitting through the display panel 305, which affects the display image effect of the display panel.
The cover plate layer 301 and the polarization layer 303 are fixed by bonding, for example, by using an optical adhesive 302.
The driving device 306 is used for driving the display panel 305 to generate sound. For example, the driving device may be an exciter or the like, and is used for driving the display panel to vibrate and generate sound, so that when the display panel is applied to an electronic device, a full-screen design of the electronic device can be realized.
The inventor finds that the pixel density of the OLED display panel and the metal wires connecting the pixels affect the transmittance of the display panel. For example, the pixel density on the OLED display panel is big more, and the metal wire of connecting the pixel is inseparabler more, causes OLED display panel's luminousness to be low, and when the camera module set up and constitute the full-face screen in display panel below, the amount of light that receives of camera module is few, influences the imaging quality of camera module. And the metal wire that connects the pixel is inseparabler more, and the micro-level hole between adjacent metal wire constitutes the light-permeable region, can cause stronger diffraction when outside light passes through the micro-level hole, influences the formation of image quality of camera module.
Optionally, the display panel 305 according to the embodiment of the present invention adopts an OLED display panel, and the pixel arrangement of the display panel 305 adopts Pentile arrangement. The pixel points of the display panel of the example are arranged in the manner of Pentile, and compared with the conventional pixel point which is composed of three red, green and blue sub-pixels, each display pixel of Pentile only has 2 different pixels, and the area of each pixel is larger, so that the manufacturing process requirement and the manufacturing cost are reduced.
Alternatively, fig. 1 shows a pixel distribution diagram of the first region of the present invention. The first region comprises a plurality of display pixels 101, and the display pixels 101 are connected through metal wires 103.
The display pixels 101 include red and green pixels and blue and green pixels. Optionally, the display pixel 101 may further include three different pixel points, for example, a red pixel point, a blue pixel point, and a green pixel point.

In this example, the pixels are arranged in a row to reduce the pixel density of the display panel and improve the light transmittance of the display panel. For example, by adopting the arrangement mode of the invention, when the display pixels are simultaneously positioned in the same odd-numbered row, two adjacent display pixels are arranged at intervals, so that the display pixels are not arranged in some areas of the first area, and the light transmittance of the first area is improved.
For example, the pixel pitch range between the cyan pixel and the red and green pixel in this example is: 0.2 mm-0.3 mm, the inventor finds that the image quality is fine and smooth within the pixel pitch range; in particular, when the pixel pitch is 0.25mm, the image formation fidelity of the region where the display pixels are arranged is improved, and the user can feel the improvement of the image formation quality realistically.
The blue-green pixel comprises a sub-pixel point blue and a sub-pixel point green, and the red-green pixel point comprises a sub-pixel point red and a sub-pixel point green. The pixel distance range between the sub-pixel point blue and the sub-pixel point green is as follows: 0.1 mm-0.3 mm, the pixel pitch range between the sub-pixel red and the sub-pixel green is: 0.1 mm-0.3 mm. The inventor finds that in the pixel pitch range, the imaging effect of the display panel is not influenced, and the quality and the fineness of the image can be improved.
As shown in fig. 1, the display pixels 101 are arranged in a third row in the vertical direction, wherein the line pitch range of the first row and the third row is: 0.5 mm-0.8 mm. The inventor finds that in the range of the line spacing, on one hand, the light-permeable area 104 between the metal line 103 and the metal line 103 can be enlarged, so that external light cannot generate diffraction phenomenon when penetrating through the light-permeable area 104, and the image definition of an image is improved; on the other hand, the display pixels 101 in the first area do not interfere in the imaging process, and the imaging effect of the display panel is improved.
As shown in fig. 1, the display pixels 101 in different odd rows are connected by metal lines 103, wherein the metal lines 103 are arranged in a concentrated manner in the area where the display pixels 101 are located, and the light permeable areas 104 are arranged in a concentrated manner between the display pixels and the display pixels in this example; the areas where the display pixels are not arranged form a plurality of light permeable areas 104, wherein the light permeable areas 104 are areas capable of transmitting external light, and when the external light passes through the light permeable areas 104, strong diffraction or diffraction does not occur, so that the image definition of the image is improved.
This example has improved the photic volume of camera module through the pixel density who reduces display panel, and then has improved the formation of image quality of camera module.
Optionally, as shown in fig. 2, the first region includes a plurality of display pixels 201, and the display pixels 201 include red-green pixels and blue-green pixels;

The first region comprises a plurality of display pixels configured to achieve an effect of displaying an image; for example, the display pixels are distributed in a rectangular array manner, wherein the arrangement manner of the display pixels in the first row of the first region is the same as the arrangement manner of the pixels in the second row.
The first region arranges the display pixels 201 in a first row, wherein the display pixels 201 include cyan pixels and red-green pixels; wherein there is the interval between two of bluish-green pixel and red green pixel, wherein the numerical value of interval predetermines the scope can be: 0.5mm to 1.0mm, and the inventor finds that in the pixel pitch range, the pixel density of the display panel is reduced, and the imaging quality of the display panel is not obviously reduced. In particular, the pixel pitch between both cyan and red pixels is 0.8 mm.
Wherein blue-green pixel includes that sub pixel point is blue and sub pixel point is green, and red-green pixel includes that sub pixel point is red and sub pixel point is green, and wherein the interval scope between sub pixel point is blue and sub pixel point is green: 0.5 mm-1.5 mm, the distance range between the red and green sub-pixel points is as follows: 0.5mm to 1.5mm, and the inventor finds that in the interval range, the pixel density of the display panel is reduced without influencing the imaging quality of the display panel. Therefore, the light receiving quantity of the camera module can be improved, and the imaging quality of the camera module is improved; and simultaneously, the functional requirements of the camera module are also met.
This example realizes reducing display panel's pixel density through the interval scope between increase pixel and the pixel and increase the interval scope between sub-pixel and the sub-pixel to improve the received light volume of camera module, and then improve the formation of image quality of camera module.

In this example, the metal lines 203 are disposed in a concentrated manner in the area where each sub-pixel is located. For example, a region 1 where the sub-pixel point blue is located, a region 2 where the sub-pixel point red is located, and a region 3 where the sub-pixel point green is located are distributed with metal wires in a concentrated manner.
A light-permeable area 204 is formed between the metal line 203 and the metal line 203 in the area where the sub-pixel is not arranged, wherein the light-permeable area 204 in the area can prevent external light from being subjected to strong diffraction or diffraction through the light-permeable area 204, and the image definition of an image is improved. The light-transmittable regions 204 of the present example are distributed in a concentrated manner between the sub-pixels.
Optionally, the pixel density of the first region ranges from 100 pixels/inch to 200 pixels/inch. As shown in fig. 1 to 2, the pixel arrangement of the first region adopts the arrangement described in the present invention, so that the pixel density of the first region is in the range: 100 pixels/inch to 200 pixels/inch. The invention finds that the pixel density of the first area is in the range, and the light transmittance of the first area can be improved under the condition of not obviously reducing the fidelity of the image displayed by the first area. When setting up the camera module in first regional below, can improve the photic volume of camera module, improve the imaging quality of camera module.
Optionally, the display panel 305 includes two first regions. For example, as shown in fig. 3, the display panel 305 includes two first regions 305a, wherein the shape of the first regions 305a is not limited to an ellipse, a rectangle, or the like. When the display panel 305 is applied to an electronic device, for example, a camera module is disposed below a first area, and the first area 305a is configured to be within an area formed by a field angle of the camera module.
The polarization directions of the linearly polarizing plates 303a corresponding to the two first regions 305a are the same. For example, the polarization directions of the linear polarizers 303a above the two first region regions are the same, that is, the linear polarizers 303a allow external light rays in the same direction to pass through the first region after forming linearly polarized light through the linear polarizers. When the display panel 305 is applied to the electronic device, for example, the camera module is arranged below the first area, when external light passes through the linear polarization piece, the external light becomes linear polarization, and the linear polarization penetrates through the first area to enter the camera module, so that the light receiving amount of the camera module is improved, the imaging quality of the camera module is improved, and the function of depth detection of the camera module is realized.
Alternatively, the linear polarizer may be selected from the vertical linear polarizer 303a shown in fig. 4a, or the linear polarizer may be selected from the horizontal linear polarizer 303b shown in fig. 4 b. As shown in fig. 4a, the vertical linear polarizer 303a allows part of the external light rays in the same direction as the vertical linear polarizer 303a to pass through, forming linearly polarized light. As shown in fig. 4b, the horizontal linear polarizer 303b allows a portion of the external light rays in the same direction as the horizontal linear polarizer 303b to pass through, forming linearly polarized light. The linear polarizer in this example is configured to improve transmittance of external light.

Where region a is the polarizing layer opposite the first region and region a is not provided with phase retarder 304.
In this example, the pixel density range of the first region is: 100-200 pixels/inch, and the camera module 308 is disposed under the first region. This example can improve the luminousness in first region under the condition that does not obviously reduce first region display image fidelity, can increase the photic volume of camera module simultaneously, improves the imaging quality of camera module and realizes camera module degree of depth detection's function.

For example, when the external light is sufficient, the working system of the camera module 308 is turned on, the external light passes through the linear polarizer, the light processing is completed, the external relationship is changed into linear polarized light, and the linear polarized light reaches the surface of the chip of the camera module to form an image for the linear polarized light. After imaging is completed, the camera module completes a deep skin detection function according to an imaging effect.
