Fig. 1 is a schematic structural view of an electronic device 100 according to an exemplary embodiment, fig. 2 is a sectional view A-A of fig. 1, and fig. 3 is an exploded schematic view of a display panel 200 according to an exemplary embodiment. As shown in fig. 1 to 3, the electronic device 100 may include a display panel 200 and a light sensor 101, and the light sensor 101 may collect external light through the display panel 200 or emit light toward the outside of the electronic device 200 through the display panel 200. The light sensor 101 may include a light collector or a light emitter. For example, the light emitter may comprise a distance sensor and the light collector may comprise an ambient light sensor or a camera sensor. Of course, in other embodiments, the electronic device 100 may also be configured with multiple light sensors at the same time, for example, a camera sensor and an environmental sensor at the same time.
In the present embodiment, as shown in fig. 2 and 3, the display panel 200 may include a substrate assembly 1, a first substrate 2, a second substrate 3, a liquid crystal layer 4, and a light transmitting portion 5. The first substrate 2, the second substrate 3, the liquid crystal layer 4 and the light-transmitting portion 5 are all disposed above the substrate assembly 1, the substrate assembly 1 may specifically be a backlight module, a polarizer, etc., and the substrate assembly 1 may further include an opening 11 corresponding to the light-transmitting portion 5, and a portion of the light sensor may be disposed in the opening 11 in a penetrating manner so as to obtain light through the light-transmitting portion 5. Further, the liquid crystal layer 4 and the light transmitting portion 5 are both located between the first substrate 2 and the second substrate 3, and the liquid crystal layer 4 may completely surround the light transmitting portion 5 as shown in fig. 4, or in other embodiments, the light transmitting portion 5 is located at an edge position of the display panel 200 as shown in fig. 5, and the liquid crystal layer 4 partially surrounds the light transmitting portion 5, and the light transmittance of the light transmitting portion 5 is independent of the wavelength of light.
Therefore, by arranging the light-transmitting portion 5, since the light-transmitting portions 5 have consistent light transmittance for light rays with different wavelengths, the proportion of the light rays with different wavelengths contained after the light rays are transmitted through the light-transmitting portions 5 is consistent with that of external environment light, which is favorable for improving the detection precision of the light sensor 101, especially when the light sensor 101 is a camera sensor, the image precision obtained by the electronic device 100 is favorable for improving, distortion is reduced, and the defect that other areas of the display structure layer have different light transmittance for light rays with different wavelengths is avoided.
It should be noted that: in this embodiment, as shown in fig. 2 and 3, the first substrate 2 is disposed closer to the substrate assembly 1 than the second substrate 3; alternatively, in other embodiments, the second substrate 3 may be disposed closer to the substrate assembly 1 than the first substrate 2, and the first substrate 2 and the second substrate 3 may be transparent glass substrates. In addition, the display panel 200 may naturally further include other structural layers besides the substrate assembly 1, the first substrate 2, the second substrate 3, the liquid crystal layer 4 and the light transmitting portion 5, for example, a color filter, a polarizer disposed on the color filter, a thin film transistor disposed between the first substrate 2 and the liquid crystal layer 4, and the like, which will not be described in detail herein. Next, since the light transmitting portion 5 is provided, a region corresponding to the light transmitting portion 5 on the display panel 200 cannot be used for display. Therefore, in order to enhance the visual effect, an icon can be displayed around the transparent portion 5 by default, and the specification of the icon can be equivalent to that of the transparent portion 5, thereby visually solving the problem that the transparent portion 5 is abrupt
In the present embodiment, the opening 11 and the light-transmitting portion 5 may be aligned such that the light sensor 101 penetrating the opening 11 is necessarily located below the light-transmitting portion 5. However, in this embodiment, the processing process for the opening 11 on the substrate 1 and the processing process for the light transmitting portion 5 are required to be high, and defective products are liable to occur. Therefore, in another embodiment, as shown in fig. 3, the projection of the light-transmitting portion 5 may cover the projection of the opening 11 in the direction indicated by the arrow a in fig. 3, that is, D1 is larger than D2 in fig. 3, so as to ensure that the light sensor 101 is located below the light-transmitting portion 5, and reduce the processing requirements on the light-transmitting portion 5 and the opening 11, and improve the yield.
Still taking fig. 4 and 5 as an example, the shape of the light-transmitting portion 5 may be designed according to the number of light sensors 101 actually required to be arranged. For example, it may be circular as shown in fig. 4, or fan-shaped as shown in fig. 5. Of course, in other embodiments, the light-transmitting portion 5 may be rectangular or elliptical, and the present disclosure is not limited thereto.
Based on the technical solution of the present application, as shown in fig. 6, the display panel 200 may further include a sealing portion 6, where the sealing portion 6 is located between the first substrate 2 and the second substrate 3 and is disposed around the liquid crystal layer 4 to block the liquid crystal layer 4, and the sealing portion 6 may specifically be a cured adhesive dispensed on an edge area of the first substrate 2. Further, the sealing portion 6 and the light-transmitting portion 5 may be made of the same material and may be formed in the same process step. For example, when the sealing portion 6 is formed by dispensing by a dispenser, the light transmitting portion 5 may be obtained by dispensing at a corresponding position.
In the above embodiments, the light transmitting portion 5 may be made of a transparent cured adhesive. For example, the opening 31 may be filled with a transparent curing paste in a liquid state, and the light transmitting portion 5 may be obtained after the transparent curing paste is cured. Wherein, the transparent curing glue can be UV curing glue or seal glue, etc., and the disclosure is not limited.
With the light sensor positioned below the light transmitting portion 5 in each of the above embodiments, since the light transmitting portions 5 have the same transmittance for light of different wavelengths, the amount of loss of light can be determined from the transmittance, and compensation can be performed. Specifically, the electronic device 100 may further include a chip component (not shown in the figure), and the chip component may calculate according to the compensation amount and the amount of light collected by the light sensor 101, so as to obtain a detection result corresponding to the light sensor 101. For example, assuming that the light sensor 101 is a camera sensor, the light transmittance of the light transmitting portion is 90%, if the light quantity collected by the camera sensor 101 is a, then the light quantity a can be compensated by 10%, that is, the camera sensor 101 can obtain image information according to the obtained 1.1A light, so as to improve the matching degree between the picture and the actual environment.
For the display panel 200 in the foregoing embodiments, the present disclosure further provides a processing process of the display panel, as shown in fig. 7, the processing process may include:
in step 701, a substrate assembly 1 is acquired.
In this embodiment, the substrate assembly 1 may include a backlight module and a lower polarizer. The backlight module can provide a light source, and the lower polarizer can filter out part of light.
In step 702, a first base plate 2 is provided on a substrate assembly 1.
In this embodiment, the first substrate 2 may include a transparent glass substrate for carrying liquid crystal and a thin film transistor disposed corresponding to the liquid crystal, which may be used to control deflection of the liquid crystal to change polarization of light.
In step 703, the light transmitting portion 5 and the sealing portion 6 are formed at predetermined positions on the first substrate 2.
In step 704, liquid crystal is injected to obtain the liquid crystal layer 4.
In this embodiment, the sealing portion 6 may be formed by dispensing in the edge area of the first substrate 2 by a dispenser, and the sealing portion 6 cooperates with the first substrate 2 to form an accommodating space into which the liquid crystal may be injected to obtain the liquid crystal layer 4. The light transmitting part 5 can be formed in the same process step with the sealing part 6 through the dispensing machine, so that when liquid crystal is injected subsequently, the liquid crystal can avoid opening the light transmitting part 5, and errors caused by different light transmittance of the liquid crystal to different wavelengths are prevented.
In step 705, the second substrate 3 is disposed over the liquid crystal layer 4.
In this embodiment, the second substrate 3 may be a transparent glass substrate, and the liquid crystal may be limited and blocked by the combined action of the first substrate 2, the second substrate 3 and the sealing portion 6. Of course, in the processing of the display panel 200, the structure of providing a polarizer, an alignment film, a color filter, etc. may be also included, and the formation of a thin film transistor, etc. may be also included, which will not be described in detail herein.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any adaptations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
