Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
Referring to fig. 1, the present application discloses an electronic device 1000, where the electronic device 1000 includes a camera 200 and a display screen assembly 100. The display screen assembly 100 is disposed in a light receiving direction of the camera 200.
The electronic apparatus 1000 may be a terminal apparatus having an operating system, which is configured with the camera 200 and the display screen assembly 100. For example, the electronic device 100 may include a smartphone, tablet computer, or other terminal device configured with a camera 200 and a display screen assembly 100.
Referring to fig. 2, 3 and 4 together, an electronic device 1000 according to an embodiment of the present disclosure includes a display panel assembly 100, where the display panel assembly 100 includes a first panel 10, a refractive medium layer 20 and a second panel 30. The refractive medium layer 20 is located between the first screen 10 and the second screen 30, the first screen 10 includes a first pixel region 12 and a first non-pixel region 14, the second screen 30 includes a second pixel region 32 and a second non-pixel region 34, an orthographic projection of the second pixel region 32 on the first screen 10 is located in the first non-pixel region 14, and the first pixel region 12 and the second pixel region 32 are used for jointly displaying a preset picture. The refractive medium layer 20 includes a refractive region 22 corresponding to the second pixel region 32, and the refractive region 22 is used for refracting the light transmitted through the first non-pixel region 14 into the second non-pixel region 34 so that the light passes through the second non-pixel region 34 and is received by the camera head 200. Here, the pixel region (the first pixel region 12 or the second pixel region 32) may refer to a region where the pixels are located, and the non-pixel region (the first non-pixel region 14 or the second non-pixel region 34) may refer to a gap between the pixels.
The electronic device 1000 according to the embodiment of the application can utilize the first pixel region 12 of the first screen 10 and the second pixel region 32 of the second screen 30 to jointly display a preset picture, so that the display brightness of the display screen assembly 100 is high, and the resolution of the display picture is also high. In addition, since the second pixel region 32 corresponds to the first non-pixel region 14, the light transmitted from the first non-pixel region 14 is easily blocked by the second pixel region 32, and the light transmitted from the first non-pixel region 14 is refracted into the second non-pixel region 34 by the refractive medium layer 20, so that the light passes through the second non-pixel region 34 and is received by the camera 200, that is, the light transmittance of the display screen assembly 100 is higher.
Referring to fig. 3, the display panel assembly 100 includes a refractive medium layer 20, the refractive medium layer 20 includes a refractive region 22 corresponding to the second pixel region 32, and the refractive region 22 is used for refracting the light transmitted through the first non-pixel region 14 into the second non-pixel region 34 so that the light passes through the second non-pixel region 34 and is received by the camera 200. Refractive medium layer 20 may be a refractive medium layer 20 formed of a Polyester (PET) film material having excellent optical properties, such as: high light transmittance, high glossiness and low haze. Meanwhile, the refractive medium layer 20 formed by the polyester film material has a smooth surface and good thermal stability. The refraction region 22 of the refraction medium layer 20 may be subjected to a refraction process, which may be chemical preparation on the refraction region 22 of the refraction medium layer 20, or may be polishing treatment or plating treatment. The refractive region 22 having high transmittance and refractive index can be obtained after the refractive process. The refractive medium layer 20 can refract the light transmitted from the first non-pixel region 14 into the second non-pixel region 34 so that the light passes through the second non-pixel region 34 and is received by the camera 200, thereby avoiding the problem that the light transmitted from the first non-pixel region 14 is blocked by the second pixel region 32, which causes the camera 200 started by the electronic device 1000 to obtain insufficient external light, and increasing the light transmittance of the display screen assembly 100, so that the image obtained by the camera 200 started by the electronic device 1000 has higher definition.
Referring to fig. 3 and 4 together, the display panel assembly 100 includes a first panel 10 and a second panel 30. The first screen 10 includes a first pixel region 12 and a first non-pixel region 14; the second screen 30 includes a second pixel area 32 and a second non-pixel area 34. The orthographic projection of the second pixel area 32 on the first screen 10 is in the first non-pixel area 14, and it can be understood that the first pixel area 12 of the first screen 10 and the second pixel area 32 of the second screen 30 are arranged in a staggered pixel distribution manner, so that when the electronic device 1000 does not activate the camera 200 and the display screen assembly 100 displays a preset picture, the first pixel area 12 and the second pixel area 32 can jointly display the preset picture. The first pixel region 12 and the second pixel region 32 can display the preset picture together relative to a single pixel region, so that the display brightness of the display screen assembly is high, and the resolution of the display picture is also high.
In the electronic device 100 of the embodiment of the present application, the second pixel region 32 of the second screen 30 includes a light-emitting sub-region 322 and a non-light-emitting sub-region 324, and the non-light-emitting sub-region 324 corresponds to the refraction region 22. When the electronic device 1000 does not start the camera 200 and the display screen assembly 100 displays a preset picture, the light-emitting sub-region 322 emits light, and the non-light-emitting sub-region 324 does not emit light; when the electronic device 1000 enables the camera 200 and the display screen assembly 100 does not display a picture, neither the light-emitting sub-region 322 nor the non-light-emitting sub-region 324 is illuminated. In some embodiments, the first pixel region 12 of the first screen 10 in the electronic device 100 may include a first light emitting sub-region 122 and a first non-light emitting sub-region 124. When the electronic device 1000 does not start the camera 200 and the display screen assembly 100 displays a preset picture, the first light-emitting sub-region 122 emits light, and the first non-light-emitting sub-region 124 does not emit light; when the electronic device 1000 enables the camera 200 and the display screen assembly 100 does not display a preset picture, neither the first light-emitting sub-region 122 nor the first non-light-emitting sub-region 124 emits light. Since the refraction area 22 only corresponds to the non-light-emitting sub-area 324, at this time, the light of the light-emitting sub-area 322 is not affected by the refraction area 22, and the light emitted by the light-emitting sub-area 322 can normally pass through the refraction medium layer 20 and the first non-pixel area 14 and then be transmitted to the outside, so that a user can conveniently observe the display image of the second screen 30. In some embodiments, the first Light Emitting sub-region 122 of the first pixel region 12 and the Light Emitting sub-region 322 of the second pixel region 32 may emit Light by using an Organic Light-Emitting Diode (OLED). When the organic light emitting diode has a proper voltage, the positive hole of the organic light emitting diode and the negative charge of the organic light emitting diode are combined in the light emitting layer to generate light. The organic light emitting diode has the characteristics of self-luminescence, high brightness and high visibility. Referring to fig. 3, the shape of each pixel in the first pixel region 12 and the second pixel region 32 may be circular, and in other embodiments, the shape of each pixel in the first pixel region 12 and the second pixel region 32 may also be rectangular, and the like. In addition, the shapes of the light-emitting sub-region 322 and the first light-emitting sub-region 122 in fig. 3 are circular, and the shapes of the non-light-emitting sub-region 324 and the first non-light-emitting sub-region 124 are also circular, and in other embodiments, the shapes of the light-emitting sub-region 322, the first light-emitting sub-region 122, the non-light-emitting sub-region 324 and the first non-light-emitting sub-region 124 may also be designed according to actual requirements, for example, rectangular, and the like, and are not specifically limited herein.
In some embodiments, the display screen assembly 100 in the electronic device 1000 may be a color display screen assembly 100, and the light-emitting sub-region 322 and the first light-emitting sub-region 122 may display three different colors of light using organic light-emitting diodes, for example: the organic light emitting diode can display light of three primary colors of red (R), green (G) and blue (B), and can be visually mixed into a color required for a preset picture using light of three different colors.
The first screen 10 of the present embodiment includes a first pixel density and the second screen 30 includes a second pixel density. The pixel density is understood to be the number of Pixels (Pixels Per Inch, PPI) possessed by the display panel assembly 100 and the main panel 300 Per Inch, and the higher the pixel density is, the more details of displaying the preset picture is enriched, and the higher the fidelity of displaying the preset picture is. As shown in fig. 3, the first pixel region 12 of the first panel 10 and the second pixel region 32 of the second panel 30 are arranged in a staggered pixel distribution manner, and a ratio of the first pixel density to the second pixel density is 1: 1, i.e., the first pixel density of the first screen 10 is equal to the second pixel density of the second screen 30. The ratio of the first pixel density to the second pixel density may also be 1: 2. 1: 3. 2: 1 or 3: 1. in some embodiments, the first pixel density of first panel 10 may be less than the second pixel density of second panel 30, for example, as shown in FIG. 5, the ratio of the first pixel density to the second pixel density is 1: 2, the first pixel area 12 is decreased, the first non-pixel area 14 is increased, the light transmitted from the first non-pixel area 14 is increased, the light passes through the second non-pixel area 34 and is received by the camera 200, so the ratio of the first pixel density to the second pixel density is 1: 2, the transmittance can be improved, so that the camera 200 receives more light rays, and the camera 200 can obtain a picture with higher definition. When the ratio of the first pixel density to the second pixel density is 1: 3, the transmittance can be increased, so that the camera 200 receives more light, which is not described herein again. In some embodiments, the first pixel density of first panel 10 may be greater than the second pixel density of second panel 30, for example, as shown in FIG. 6, with a ratio of 3: 1, the second pixel area 32 is reduced, the second non-pixel area 34 is increased, and the gap between the pixels on the second screen 30 is increased, so that the camera 200 can receive more light rays, and the camera 200 can obtain a picture with higher definition. Meanwhile, the ratio of the first pixel density to the second pixel density is 3: 1 can weaken the layering sense that display screen subassembly 100 shows the predetermined picture, make display screen subassembly 100 have better visual effect, in some embodiments, electronic equipment 1000 includes the glass apron, the glass apron can be used for protecting display screen subassembly 100, first pixel region 12 on the first screen 10 can see through the glass apron and show the predetermined picture, and second screen 30 is then through the glass apron, show the predetermined picture behind first screen 10 and the refraction dielectric layer 20, refraction dielectric layer 20 can not exert an influence to the predetermined picture that first pixel region 12 on the first screen 10 shows, and can reduce the display luminance of second screen 30. When the ratio of the first pixel density to the second pixel density is 3: 1, the display screen assembly 100 can have better visual effect because the display effect of the first screen 10 is better than that of the second screen 30.
Referring to fig. 1 again, the electronic device 100 of the embodiment of the application further includes a main panel 300, the main panel 300 includes a third pixel density, and both the first pixel density and the second pixel density are less than the third pixel density. When the first pixel density and the second pixel density are both smaller than the third pixel density, the areas of the first non-pixel region 14 and the second non-pixel region 34 are larger, more light rays are transmitted from the first non-pixel region 14, the light rays are refracted into the second non-pixel region 34 so that the light rays pass through the second non-pixel region 34 and are received by the camera 200, and the external light rays obtained by the camera 200 are sufficient so that the definition of a picture obtained by the camera 200 is higher.
In the electronic device 100 of the embodiment of the present application, the sum of the first pixel density and the second pixel density is equal to the third pixel density. For example: the third pixel density is 400, i.e., the number of pixels per inch is 400, the first pixel density may be 200, and the second pixel density may be 200. When the sum of the first pixel density and the second pixel density is equal to the third pixel density, the transmittance can be increased, so that the camera 200 can obtain enough external light, and the brightness of the preset image displayed by the display screen assembly 100 and the main screen 400 can be ensured to be consistent.
