The camera module 30 in the electronic device 100 is located opposite to the first display portion 11 of the first display screen 10. That is, the camera module 30 is disposed below the first display portion 11 of the display screen 10. The area of the orthographic projection of the camera module 30 on the display screen 10 is smaller than the area of the first display part 11. Therefore, when the first display portion 11 is not powered on, the camera module 30 can capture an image through the first display portion 11.
Because camera module 30 can see through the first display part 11 of display screen 10 and gather the image to camera module 30 need not to occupy the non-display area of display screen 10, also need not to set up extra non-display area for camera module 30 on the display screen 10, can reduce the non-display area of display screen 10, thereby can improve electronic equipment 100's screen occupation ratio.
The display screen 10 includes a first end surface 121, a second end surface 122, a third end surface 123 and a fourth end surface 124. The first end surface 121 is disposed opposite to the second end surface 122, for example, the first end surface 121 and the second end surface 122 may be two opposite short ends of the display screen 10. The third end surface 123 is disposed opposite to the fourth end surface 124, for example, the third end surface 123 and the fourth end surface 124 may be two opposite long ends of the display screen 10.
Wherein the first display portion 11 may be located at any one end surface. For example, the first display portion 11 may be located at the first end surface 121.

The backlight 14 of the display screen 10, the first driving chip 13A, and the second driving chip 13B are respectively disposed on different end surfaces of the display screen 10. For example, the backlight 14 may be disposed on a first end surface 121 of the display screen 10, and the first driving chip 13A and the second driving chip 13B may be disposed on a second end surface 122 of the display screen 10.
In some embodiments, referring to fig. 5 and 6 together, fig. 5 is a sectional view of the display screen 10 of the electronic device shown in fig. 1 along a direction P1-P1, and fig. 6 is another sectional view of the display screen 10 of the electronic device shown in fig. 1 along the direction P1-P1.
The display screen 10 includes a first substrate 15A and a second substrate 15B. The first substrate 15A and the second substrate 15B are disposed at an interval. The first substrate 15A and the second substrate 15B are made of transparent materials, so that light can penetrate through the substrates easily. For example, the first substrate 15A and the second substrate 15B may be made of a transparent material such as glass or plastic, or may be made of a mixture of a plurality of transparent materials.
The first substrate 15A includes a driving function surface 151. The drive function surface 151 may be a surface of the first substrate 15A opposite to the second substrate 15B. That is, the second substrate 15B is located on the side of the driving function surface 151 of the first substrate 15A. The driving function surface 151 may be provided with a circuit, for example, a Thin Film Transistor (TFT) circuit.
The driving function surface 151 includes a predetermined region 151A thereon. The preset area 151A corresponds to the first display part 11 of the display screen 10. That is, the preset region 151A and the structures on both sides of the preset region 151A together form the first display portion 11. The preset region 151A may have a regular shape such as a rectangle or a circle, or may have an irregular shape.
Wherein the periphery of the preset area 151A is provided with an isolation structure 16. The isolation structure 16 is connected to the first substrate 15A and the second substrate 15B. The isolation structure 16 is a hollow ring structure as a whole.
In some embodiments, the material of the isolation structure 16 may include a light-shielding adhesive.
The first substrate 15A and the second substrate 15B are disposed at an interval, the isolation structure 16 is disposed between the first substrate 15A and the second substrate 15B, and the isolation structure 16 is connected to both the first substrate 15A and the second substrate 15B, so that the first substrate 15A, the isolation structure 16, and the second substrate 15B may together form a first accommodating space 101 and a second accommodating space 102. Wherein the second accommodating space 102 surrounds the periphery of the first accommodating space 101.
Wherein, the first accommodating space 101 is provided with a first liquid crystal material 18, and the second accommodating space 102 is provided with a second liquid crystal material 19. The light transmittance of the second liquid crystal material 19 when not powered is less than the light transmittance of the first liquid crystal material 18 when not powered. Thus, the first liquid crystal material 18 has a better optical transparency than the second liquid crystal material 19 when not powered.
In some embodiments, the second liquid crystal material 19 is a normal liquid crystal. The transmittance of the second liquid crystal material 19 does not change, or only changes slightly, upon power-up. For example, when the second liquid crystal material 19 is not powered, the transmittance of the second liquid crystal material 19 is greater than 90%, and after the power is powered, the transmittance of the second liquid crystal material 19 is still greater than 90%.
The first liquid crystal material 18 is a scattering liquid crystal. When not powered, the first liquid crystal material 18 is in a fully transparent state, or near fully transparent state. That is, the transmittance of the first liquid crystal material 18 may reach 100% or close to 100% when not powered on. Upon power up, the light transmittance of the first liquid crystal material 18 decreases. For example, after power-up, the light transmittance of the first liquid crystal material 18 decreases to 80%.
The first display portion 11 of the display screen 10 includes the first liquid crystal material 18, and portions of the first substrate 15A and the second substrate 15B located on both sides of the first liquid crystal material 18. It will be appreciated that the first display portion 11 may also include TFT circuitry or the like on one or both sides of the first liquid crystal material 18.
In addition, since the polarizer blocks light, which affects the image capturing effect of the camera module, the first display portion 11 may not include a polarizer. That is, neither side of the first liquid crystal material 18 is provided with a polarizer.
The second display portion 12 of the display screen 10 comprises the second liquid crystal material 19 and portions of the first substrate 15A and the second substrate 15B on both sides of the second liquid crystal material 19. It will be appreciated that the second display section 12 may also include TFT circuitry or the like on one or both sides of the second liquid crystal material 19.
In addition, the second display portion 12 may further include a polarizer on one or both sides of the second liquid crystal material 19.
In some embodiments, the peripheral edge of the first substrate 15A and the peripheral edge of the second substrate 15B are further provided with a light shielding structure 17. The light shielding structure 17 is connected to the periphery of the first substrate 15A and the periphery of the second substrate 15B. Thus, the light shielding structure 17 may seal the second receiving space 102.
In some embodiments, the material of the light shielding structure 17 may include a light shielding glue.
In some embodiments, reference is also made to fig. 1, wherein the camera module 30 is disposed between the housing 20 and the display screen 10. When the camera module 30 is disposed under the display screen 10, the position of the camera module 30 is opposite to the position of the first liquid crystal material 18. That is, the camera module 30 is located below the first liquid crystal material 18.
The area of the orthographic projection of the camera module 30 on the display screen 10 is smaller than the area of the first liquid crystal material 18. Thus, the camera module 30 can collect images through the first liquid crystal material 18 of the display screen 10.
When the camera module 30 needs to collect an image, the driving chip 13A of the first display portion 11 of the display screen 10 can control the first liquid crystal material 18 not to be powered on, so as to ensure that the light transmittance of the first liquid crystal material 18 can meet the requirement of the camera module 30 for collecting an image.
When the camera module 30 does not need to capture an image, the driving chip 13A of the first display portion 11 of the display screen 10 may control the first liquid crystal material 18 to be powered on, so that the first display portion 11 of the display screen 10 displays information.
The first display section 11 and the second display section 12 of the display screen 10 are driven in an independent driving manner. Thus, the first display portion 11 does not affect the second display portion 12 either when displaying information or when not displaying information. The driving chip 13B of the second display portion 12 may control the second liquid crystal material 19 to be powered on or off regardless of whether the first liquid crystal material 18 is powered on or off.
In some embodiments, the electronic device 100 further comprises a processor. For example, the processor may be provided on the main board 40 of the electronic device 100. The processor may be electrically connected to the first driving chip 13A and the second driving chip 13B to control the first driving chip 13A and the second driving chip 13B, so as to control the first display portion 11 and the second display portion 12 of the display screen 10. In addition, the processor may be further configured to control the camera module 30.
In some embodiments, when the processor receives the photographing instruction, the processor may control the camera module 30 to capture an image through the first liquid crystal material 18 of the display screen 10. The shooting instruction may be a touch instruction, such as a sliding operation, a clicking operation, or a long-pressing operation on the display screen. The photographing instruction may also be a pressing operation on a physical key of the electronic apparatus 100. In addition, the shooting instruction may also be a voice instruction. The shooting instruction is used for controlling the camera module 30 to be started to collect images, or the shooting instruction is used for starting the camera module 30 to shoot.
It should be noted that when the display screen 10 is in a display state or displaying a picture, the camera module 30 is not convenient to capture an image through the first liquid crystal material 18. Therefore, when the processor receives a shooting instruction, the processor can control the first liquid crystal material 18 to be in a transparent state, and then control the camera module 30 to collect an image through the first liquid crystal material 18 in the transparent state, so that an image with better quality can be obtained.
In some embodiments, when the processor receives the shooting instruction, the processor determines whether the portion of the display screen 10 located in the first liquid crystal material 18 displays a picture according to the received shooting instruction, that is, determines whether the first display portion 11 of the display screen 10 displays a picture. The processor then controls the state of the first liquid crystal material 18 and controls the camera module 30 according to the determination result.
When the judgment result is that the part of the display screen 10 located in the first liquid crystal material 18 does not display a picture, that is, is not in a display state, the processor may directly control the camera module 30 to acquire an image through the first liquid crystal material 18.
When the judgment result is that the display screen 10 is located on a part of the display screen of the first liquid crystal material 18, that is, in a display state, the processor may control the first liquid crystal material 18 to be in a transparent state according to the received shooting instruction. The processor then controls the camera module 30 to capture an image through the first liquid crystal material 18.
In some embodiments, when the camera module 30 captures an image through the first liquid crystal material 18, the processor is further configured to control a portion of the display screen 10 located on the second liquid crystal material 19 to display according to the received display instruction, that is, control the second display portion 12 of the display screen 10 to display a picture. Wherein the display instruction is used for instructing the display screen 10 to display a picture. The display instruction may be triggered by a user, for example by the user pressing or sliding a display screen. The display instruction may also be automatically triggered by the electronic device 100. For example, when the user clicks a parameter setting touch key on the display screen 10, the second display portion 12 of the display screen 10 may display a setting interface of the photographing parameters.
In some embodiments, referring to fig. 6 and 7 simultaneously, fig. 7 is a further cross-sectional view of the display screen 10 in the electronic device shown in fig. 1 along the direction P1-P1.
Wherein a first via 161 is formed on the isolation structure 16. The first through hole 161 may be a through hole having any shape, such as a circular hole or a square hole. In the manufacturing process of the display panel 10, the first liquid crystal material 18 may be injected into the first receiving space 101 through the first through hole 161.
After the first liquid crystal material 18 is injected into the first receiving space 101, a first sealing member 162 may be disposed in the first through hole 161. The shape and size of the first sealing member 162 are adapted to the shape and size of the first through hole 161. The first sealing member 162 is used to seal the first through hole 161.
In some embodiments, the material of the first sealing element 162 includes a light shielding glue.
Wherein, the light shielding structure 17 is formed with a second through hole 171. The second through hole 171 may be a through hole having any shape, such as a circular hole or a square hole. In the manufacturing process of the display panel 10, the second liquid crystal material 19 may be injected into the second receiving space 102 through the second through hole 171.
After the second accommodating space 102 is filled with the second liquid crystal material 19, a second sealing member 172 may be disposed in the second through hole 171. The shape and size of the second seal 172 are adapted to the shape and size of the second through hole 171. The second sealing member 172 is used to seal the second through hole 171.
In some embodiments, the material of the second sealing member 172 includes a light shielding glue.
In the manufacturing process of the display panel 10, the first liquid crystal material 18 is first injected into the first accommodating space 101 through the first through hole 161, and then the first through hole 161 is sealed by the first sealing member 162. Then, the second liquid crystal material 19 is injected into the second receiving space 102 through the second through hole 171, and finally, the second through hole 171 is sealed with the second sealing member 172.
Therefore, in the production process of the display screen 10, the first liquid crystal material 18 injected into the first accommodating space 101 and the second liquid crystal material 19 injected into the second accommodating space 102 do not mix.
In some embodiments, referring to FIG. 8, FIG. 8 is a cross-sectional view of the display screen 10 of the electronic device of FIG. 1 taken along the direction P2-P2.
Wherein the second substrate 15B includes a projection 152. The protruding portion 152 protrudes from an edge of one end of the first substrate 15A. The backlight 14 of the display screen 10 is disposed on the projection 152. Thus, the backlight 14 may provide a source of light for the first liquid crystal material 18.
The portion of the light shielding structure 17 facing the backlight 14 may be transparent, so as to facilitate light emitted from the backlight 14 to enter the display screen 10. For example, the portion of the light shielding structure 17 facing the backlight 14 may be made of transparent glass.
In some embodiments, a step structure may be disposed on the protrusion portion 152. The backlight 14 may be disposed on the stepped structure.
In some embodiments, referring to fig. 9 simultaneously, fig. 9 is a schematic structural diagram of the backlight 14 in the display screen 10 shown in fig. 8.
The backlight 14 may include a plurality of sub-light sources 141 arranged at intervals. The plurality of sub light sources 141 are for emitting monochromatic light. The sub-light sources emitting different color monochromatic light among the plurality of sub-light sources 141 are sequentially arranged.
For example, the plurality of sub light sources 141 may include a sub light source emitting red (R) light, a sub light source emitting green (G) light, and a sub light source emitting blue (B) light. The sub-light sources emitting R, G, and B colors are arranged in sequence, for example, may be arranged in sequence according to a combination of RGB.
Wherein the plurality of sub-light sources 141 are configured to alternately emit incident light in a field sequential manner. The incident light is incident on the first liquid crystal material 18 through the first substrate 15A or the second substrate 15B. For example, the incident light may be reflected by the first substrate 15A and then incident on the first liquid crystal material 18, may be reflected by the second substrate 15B and then incident on the first liquid crystal material 18, or may be reflected by both the first substrate 15A and the second substrate 15B and then incident on the first liquid crystal material 18.
When the camera module 30 of the electronic device 100 needs to capture an image, the first driving chip 13A in the display screen 10 may control the first liquid crystal material 18 not to be powered on. At this time, the first liquid crystal material 18 is in a transparent state. The electronic device can control the light emitting angle of the backlight 14, so that the incident light emitted by the backlight 14 is fully emitted between the first substrate 15A and the second substrate 15B, and at this time, the light cannot be transmitted out from the first display portion 11 of the display screen 10, so that the first display portion 11 does not display information, and the camera module 30 is favorable for collecting images.
When the camera module 30 of the electronic device 100 does not need to capture an image, the first driving chip 13A in the display screen 10 may control the first liquid crystal material 18 to be powered on. At this time, the first liquid crystal material 18 is in a scattering state. The first liquid crystal material 18 can change the transmission angle of the incident light emitted from the backlight 14, so that the incident light no longer satisfies the condition of total reflection, but is scattered between the first substrate 15A and the second substrate 15B, so that the incident light is transmitted from the first substrate 15A or the second substrate 15B, and the first display portion 11 can normally display information.
Therefore, through the control of the first driving chip 13A, the first display part 11 of the display screen 10 can meet the requirement of the camera module 30 for collecting images, and can also enable the first display part 11 to normally display information.
In the electronic device 100 provided by the embodiment of the application, the display screen 10 includes the first display part 11 and the second display part 12, the light transmittance of the first display part 11 is greater than the light transmittance of the second display part 12, so that the camera module 30 can collect images through the first display part 11 of the display screen 10, the camera module 30 does not need to occupy a non-display area of the display screen 10, that is, the camera module 30 does not need to be provided with an additional non-display area, the area of the non-display area of the display screen 10 can be reduced, and the screen occupation ratio of the electronic device 100 can be improved.
