It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
As used herein, AN "electronic device" (or simply "terminal") includes, but is not limited to, devices configured to receive/transmit communication signals via a wireline connection (e.g., via a Public Switched Telephone Network (PSTN), a digital subscriber line (DS L), a digital cable, a direct cable connection, and/or another data connection/network) and/or via a wireless interface (e.g., for a cellular network, a wireless local area network (W L AN), a digital television network such as a DVB-H network, a satellite network, AN AM-FM broadcast transmitter, and/or another communication terminal).
It should be noted that the electronic device in the embodiment of the present application is mainly directed to a structure having a full-screen structure or a structure having an off-screen camera or an off-screen light sensing element. Of course, the electronic device in the embodiment of the present application may also be understood as an electronic device having a light sensing element or a camera structure under a display screen, for example, a mobile phone, where a front camera of the mobile phone is hidden under the display screen, so as to improve the screen occupation ratio of the whole device, and achieve the effect that the whole device has no black edge.
Referring to fig. 1 to fig. 2 in combination, fig. 1 is a schematic structural diagram of an electronic device 100 according to some embodiments of the present application, and fig. 2 is a schematic partial structural diagram of the electronic device 100 according to fig. 1. It should be noted that the electronic device in the present application may include a mobile phone, a tablet computer, a notebook computer, a wearable device, and the like. The electronic device 100 may generally include the following structure: a display module 10, a light sensor 20 and a housing 30. The display module 10 and the housing 30 are connected and jointly enclosed to form an accommodating space 31, and the light sensing element 20 is disposed in the accommodating space 31. The display module 10 has a light emitting surface 101, and the light emitting surface 101 is disposed on a side of the display module 10 away from the accommodating space 31. The light sensing element 20 is located on a side away from the light emitting surface 101 of the display module, and the light sensing surface of the light sensing element 20 faces the display module 10, so that the external light is incident on the light sensing surface of the light sensing element 20 through the display module 10.
In order to further improve the screen occupation ratio of the whole machine, realize the effect that the whole machine has no black edge, and reduce the space occupied by light sensing devices such as a camera and the like on a display screen, the trend of the future design scheme of the whole machine is realized.
In order to eliminate the reflection of ambient light, the display module in the related art has a polarizer disposed on the surface of the panel, but the polarizer substantially filters out 50% of the light emitted from the display module. Then, in order to achieve the same intensity of light output, the display module generally needs to emit 2 times of light, which results in increased power consumption of the screen.
The applicant finds in research that the structure mode of the color film is adopted to replace the polarizer structure, so that the light emitting of the display module can not be filtered, and the power consumption of the screen can be reduced. The applicant further researches and discovers that a black opaque substance exists in a color film structure, so that a large part of the black opaque substance can shield external light rays, penetrate through a display module and enter light-sensitive devices such as a camera inside the whole machine, the structural mode of the camera or the light-sensitive devices under the screen cannot be realized, and the screen occupation ratio of the whole machine cannot be improved.
For solving the above problem, the idea of this embodiment is to set up the color filter structure as a partially light-permeable structure, so that external light can pass through the display module and enter the camera or the light sensing device inside the complete machine, the structural mode of the camera or the light sensing device under the screen is realized, and the screen occupation ratio of the complete machine is further improved.

Referring to fig. 6, fig. 6 is a partial structural schematic view of a light emitting device 12 in some embodiments of the present disclosure, in which the light emitting device 12 substantially includes a first electrode 121, a second electrode 122, and a light emitting layer 123 disposed between the first electrode 121 and the second electrode 122, a direction of the light emitting layer 123 pointing to the first electrode 121 is a light emitting direction L of the display module 10, and the light emitting layer 123 is disposed corresponding to the display area 131 for normal display of the display area 131.

Referring to fig. 7, fig. 7 is a schematic plan view of a portion of the display layer 13 in some embodiments of the present disclosure, the display area 131 and the non-display area 132 of the display layer 13 are substantially arranged at intervals, for example, the non-display area 132 is arranged around the display area 131, or the display area 131 is arranged around the non-display area 132, and of course, the interval between the display area 131 and the non-display area 132 may also be in other forms.
Further, the display region 131 includes a plurality of color cells 1311(R cells, G cells, B cells, etc.) arranged at intervals, and the non-display region 132 includes a plurality of black cells 1322 which are not light-transmissive. The black cells 1322 are filled between the spaced color cells 1311.
Specifically, the plurality of color cells 1311 includes at least one first color cell (R cell), at least one second color cell (G cell), and at least one third color cell (B cell). The light emitting element 12 includes a plurality of sub-pixels, for example, a first sub-pixel (R pixel), a second sub-pixel (G pixel), and a third sub-pixel (B pixel). Wherein the plurality of color cells 1311 are disposed corresponding to different color pixels of the light emitting element 12.
Further, a first color unit (R unit) is disposed corresponding to the first sub-pixel (R pixel), and the emission color of the first sub-pixel (R pixel) is identical to the color of the first color unit (R unit); the second color unit (G unit) is arranged corresponding to the second sub-pixel (G pixel), and the light-emitting color of the second sub-pixel (G pixel) is consistent with the color of the second color unit (G unit); the third color unit (B-cell) is disposed corresponding to the third sub-pixel (B-pixel), and the emission color of the third sub-pixel (B-pixel) is identical to the color of the third color unit (B-cell).

Further, the black unit 1322 is filled between the plurality of color units 1311 disposed at intervals to prevent light leakage and influence on the photoelectric characteristics. It is understood that the black unit 1322 may be disposed above the plurality of color cells 1311, between the plurality of color cells 1311, or below the plurality of color cells 1311 in a direction substantially perpendicular to the display module 10. The embodiment of the present application is exemplified in that the black cells 1322 are disposed under the plurality of color cells 1311, that is, the non-display region 132 is disposed under the display region 131.
Specifically, the black cells 1322 are made of a black photoresist material to prevent light leakage. Of course, in other embodiments, the black cells 1322 may also be made of black opaque material, which is not illustrated in this embodiment.
It can be understood that the projection of the non-display region 132 in the direction substantially perpendicular to the display module 10 covers a portion of the metal gap 1111, and the light-transmitting hole 1321 corresponds to the portion of the metal gap 1111 to form an incident light path i of the external light, so that the light sensor 20 disposed below the display module 10 can sense the light signal. In other words, the light-transmitting hole 1321 is opened in the black unit 1322, and the area of the light-transmitting hole 1321 is not smaller than the area of the metal gap 1111, so that the metal gap 1111 is completely covered by the external light when the external light enters from the light-transmitting hole 1321.
Further, the metal slot 1111 may have various shapes, such as a circle, a triangle, a quadrangle, a polygon, and the like, based on the layout of the driving circuit and the transmission signal traces. It will be appreciated that the shape of the light-transmitting hole 1321 substantially corresponds to the shape of the metal slot 1111, such as a circle, a triangle, a quadrangle, a polygon, and the like. In the embodiment of the present application, the shapes of the metal slit 1111 and the light transmission hole 1321 are both circular.
Further, the light-transmitting hole 1321 is opened in the black unit, and the light-transmitting hole 1321 is provided in plural, so that the metal slot 1111 corresponding to the light-transmitting hole 1321 may be plural. In the embodiment of the present application, the number of the metal slits 1111 and the light-transmitting holes 1321 is two for exemplary explanation.
Referring to fig. 8, fig. 8 is a partial structural schematic view of the light-transmitting holes 1321(D1, D2) and the metal slits 1111(D1, D2) in some embodiments of the present disclosure, where the D1 light-transmitting hole 1321 corresponds to the D1 metal slit 1111, and the D2 light-transmitting hole 1321 corresponds to the D2 metal slit 1111. The diameter of the light-transmitting hole 1321 of the D1 is larger than that of the metal gap 1111 of the D1, and the diameter of the light-transmitting hole 1321 of the D2 is not smaller than that of the metal gap 1111 of the D2, so that the metal gap 1111 can be completely covered by outside light when the outside light enters from the light-transmitting hole 1321, and the light sensing element 20 can be normally used.
The diameter or area of the light hole D1 may be the same as or different from the diameter or area of the light hole D2, and those skilled in the art can adapt the diameter or area according to the specific structural layout of the display module 10.
Further, the pixel colors of the sensed light are substantially different for different light-sensing elements 20. Further research by the applicant finds that when external light directly enters the photosensitive element 20 from the light-transmitting hole 1321, the photosensitive effect is not good. And due to the existence of the light hole 1321, the display module 10 cannot achieve the effect of integral black when the screen is turned off.
Based on the above problem, the applicant finds that, based on the pixel color of the light sensed by the light sensing element 20 itself, the corresponding color unit is covered on the light hole 1321, so that the integral black effect of the display module 10 when the display module is turned off can be enhanced.
Referring to fig. 9, fig. 9 is a schematic structural diagram of a display module 10 according to another embodiment of the present application, in which a fourth color unit (W unit) is covered on the light-transmitting hole 1321, and a color of the fourth color unit (W unit) is consistent with a color sensed by the light sensing element 20.
Further, the color of the fourth color cell (W cell) is the same as one of the first color cell (R cell), the second color cell (G cell), and the third color cell (B cell), or the color of the fourth color cell (W cell) is different from the colors of the first color cell (R cell), the second color cell (G cell), and the third color cell (B cell).
For example, when the light sensing element 20 senses the color of light as green light, the fourth color cell is the same as the second color cell (G cell). The light of the first sub-pixel (R pixel) and the third sub-pixel (B pixel) of the light emitting element 12 does not reach the light transmitting hole 1321. Therefore, the color cross phenomenon can be avoided, and meanwhile, the integral black effect can be enhanced when the display module 10 is turned off.
It can be understood that the fourth color unit completely covers the light transmission hole 1321 to prevent the light leakage phenomenon.
The display module assembly that this application embodiment provided, through set up the light trap on the black unit of adiacticity, cover the fourth colour unit the same with the colour of photosensitive element response simultaneously on the light trap, can also strengthen when putting out the screen integrative black effect when avoiding taking place the cross color phenomenon.

The display module is connected with the shell and jointly enclosed to form an accommodating space, and the light sensing element is arranged in the accommodating space. The light sensing element is located on one side departing from the light emitting surface of the display module, and the light sensing surface of the light sensing element faces the display module, so that external light rays are incident to the light sensing surface of the light sensing element through the display module.

The electronic equipment that this application embodiment provided sets up the light trap through the non-display area at the display layer to form the incident light path of external light with the metal gap cooperation of metal level, make the light sense element of locating the display module group below can carry out the light signal response. In other words, the non-display area of the display layer is provided with the light-transmitting hole, and the light-transmitting hole is matched with the metal gap of the metal layer to provide the light transmittance required by the light-sensing element, so that the light-sensing element can be normally used.
