Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 is a schematic side view of a display device according to an embodiment, and fig. 2 is a schematic perspective view of the structure shown in fig. 1. As shown in fig. 1-2, a display device may include a substrate 1 and a light emitting module 2 (shown in fig. 1) disposed on the substrate 1, wherein the light emitting module 2 may have a functional area 21 (shown in fig. 2), and the substrate 1 has a functional module (not shown) disposed corresponding to the functional area 21; for example, when the functional module is in the operating state, the transmittance of the portion of the light-emitting module located in the functional area 21 is increased to make the functional module in the light-transmitting state, so that the light-transmitting light-emitting module can be conveniently injected or injected, and the light-emitting module 2 covering the functional module is prevented from adversely affecting the normal operation of the functional module. That is, when the functional module is in a non-operating state such as a sleep state or a shutdown state, all of the light emitting modules 2 emit light normally (i.e., the portion of the light emitting module 2 located in the functional region 21 also emits light normally), so that narrow-frame or frameless display in each side direction can be realized when the functional module does not operate, and when the functional module needs to operate, the portion or all of the region located in the functional region 21 can be in a light-transmitting state according to needs, so that external light can be transmitted to the functional module (e.g., a photosensitive device, a camera, etc.) disposed on the substrate 1 through the functional region 21, and meanwhile, the functional module (e.g., a logo, a functional key, etc.) can also be displayed through the functional region 21.

For example, as shown in fig. 2, when the functional area 21 is in a transparent state, the display device may present a narrow frame or no frame in three lateral directions, and if the functional area 21 also displays normally (e.g., full screen video), the display device may realize a narrow frame or no frame in four lateral directions (i.e., all directions).

The display device fully covers the substrate through the transparent display module, and the specific area is in a light-transmitting state when some functional modules are arranged, so that the narrow-frame or frameless display is realized to the maximum extent, and functional components such as a front camera, a photosensitive device or an earphone and the like are not required to be arranged on the front surface of the electronic equipment.

Fig. 3 is a schematic perspective view of a display device according to an embodiment. As shown in fig. 3, in another alternative embodiment, the functional module on the substrate 1 may include a plurality of functional units (not shown), and the functional area 21 on the light emitting module 2 may include a plurality of functional unit areas (see fig. 3) corresponding to the positions where the functional units are disposed, and the functional area 21 may be used as a whole to adjust the transmittance, or may be used to independently adjust the transmittance in real time according to specific requirements and according to the working states of the functional units corresponding to (i.e., covered by) the functional unit areas. For example, if any one of the functional units is in normal operation, the whole functional area 21 may be set in a transparent state, or only the functional unit area covering the functional unit may be set in a transparent state, while the other functional unit areas may be set in a normal display state, and for a functional unit such as a handset that does not need to transmit light, the transparency of the functional area 21 does not need to be adjusted.

Fig. 4 is a schematic view of the structure of the substrate shown in fig. 3. As shown in fig. 3 to 4, in an alternative embodiment, based on the structure shown in fig. 3, the functional module may include a plurality of functional units that need to be disposed in front, such as a front camera unit, a photosensitive unit, and an earpiece unit, and the front camera unit and the photosensitive unit may be disposed in the same area, and an earpiece opening (not shown) is formed at a top end (i.e., a side surface) corresponding to a position where the earpiece unit is disposed, so as to output sound.

Specifically, as shown in fig. 3 to 4, a functional module area 11 located on one side (e.g., the top) of the substrate 1, a screen display area 14 located in the middle of the substrate 11, and

screen circuit areas

12 and 13 located on two opposite sides of the screen display area 14 are disposed on the substrate 1, the position of the functional module area 11 corresponding to the functional area 21 is correspondingly located on one side of the screen display area 14, and the functional module area 11 may include a front camera area 111, a chip bonding area 112, and other functional unit areas 113; in the front camera area 111, a front camera through hole (i.e. a dashed circle shown in fig. 4) may be formed in the substrate 1 for disposing a front camera unit; the photosensitive unit can be disposed in the front camera area 111 (as shown in fig. 4), or the photosensitive unit area and the earpiece unit area can be disposed in the chip binding area 112 together according to the requirement, and the other functional unit areas 113 can be disposed with trademark marks according to the specific requirement.

In another alternative embodiment, the photosensitive unit area is disposed in the pre-camera area 111, the earpiece unit area is disposed in the chip bonding area 112, and the mark unit area is disposed in the earpiece unit area 113; at this time, when the earphone unit works, the current light transmission state of the chip binding region 112 can be maintained as there is no requirement for the light transmission of the screen; when the photosensitive unit or the front camera unit works, since the photosensitive unit and the front camera unit need to collect external light, the transmittance of the front camera area 111 needs to be improved, sometimes, in order to achieve an expected effect on the transmittance of the area, the display state of the front camera area 111 can even be turned off, so that external sufficient light can penetrate through the front camera area 111 and enter the front camera unit and the photosensitive unit; similarly, when the marking unit works, since the image information such as the trademark should be displayed through the other functional unit regions 113, the transmittance of the other functional unit regions 113 should be increased, so that the light emitted or reflected by the marking unit can be emitted out of the light emitting module 2 through the other functional unit regions 113.

It should be noted that fig. 1 to 4 are only schematic structural diagrams of the display device, and a plurality of film structures may be further disposed between the substrate 1 and the light emitting module 2 according to actual process requirements, which may be specifically referred to the following embodiments:

FIG. 5 is a schematic cross-sectional view of a composite layer as a substrate in one embodiment. As shown in fig. 4 to 5, in another alternative embodiment, a composite layer including a substrate is used as the substrate S of the light emitting module 2, that is, the substrate S may include a substrate 101, an adhesive layer 102, a buffer layer 103, a screen circuit layer 104 and an insulating layer 105, which are sequentially stacked, and the screen circuit layer 104 may be disposed in the

screen circuit regions

12 and 13 and connected to the light emitting module 2 through a connection line 106 penetrating through the insulating layer 105 to drive the light emitting module 2 to emit light for display; in the front camera area 111, the substrate 101 may be formed with a front camera via, the Panel circuit layer 104 may include structural components such as an EM circuit, a GIP (Gate Drive IC In Panel) circuit, and a power signal portion, and the insulating layer 105 may include a power path portion and a signal path portion.

Fig. 6 is a schematic cross-sectional view of a light emitting module according to an embodiment. As shown in fig. 5 to 6, based on the structure shown in fig. 5, the light emitting module 2 may include a circuit layer 201, an anode layer 202, a hole layer 203, a light emitting layer 204, an electron layer 205, and a cathode layer 206, which are sequentially stacked; the circuit layer 201 is located above the screen body circuit layer 104 and connected to the screen body circuit layer 104 through the connection line 106, so as to drive the thin film transistor in the circuit layer 201 to operate through the screen body circuit layer 104, and further drive the light emitting layer 204 to emit light.

In the above embodiment, the screen body circuit layer is transferred to the substrate, that is, the screen body circuit layer is disposed below the circuit layer, so that the peripheral circuit area in the existing display device can be effectively reduced, the frame of the display device can be greatly reduced, and even the frameless design of the display device can be realized.

Fig. 7 is a schematic cross-sectional view of a display device in another embodiment. In another alternative embodiment, as shown in fig. 7, the light emitting module 2 may be sealed and protected while the light emitting module 2 is fixed on the substrate 1 by the encapsulation layer 3.

In the above embodiments, the driving signals may sequentially scan the pixel array along the extending direction of the chip bonding area 112 to illuminate the display device; meanwhile, the working state of the functional area 21 of the transparent invention module 2 can be controlled through the driving time sequence, so that the light-transmitting state of the functional area 21 can be adjusted according to the working state of the functional unit positioned below the functional area, and the selective full-screen narrow-frame and frameless design of the display device can be realized.

FIG. 8 is a schematic diagram of the structure of an electronic device in one embodiment. In an alternative embodiment, an electronic device may include an electronic device body 42 and a display screen 41 connected to the electronic device body, and the display screen 41 may be the display device described in any of the above embodiments, so as to implement a narrow-frame and frameless design with at least three sides of the electronic device.
