Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 5, an embodiment of the invention discloses a display module, which can be applied to an electronic device having an optical device 500, wherein the display module has a light-transmitting area X, and the light-transmitting area X is an area of the display module corresponding to a field range of the optical device 500. Optionally, the optics 500 includes at least one of a fingerprint module, a camera, and a sensor.
The display module may specifically include a first substrate 100, a second substrate 200, a transparent cover 330 and a light-gathering portion 400, wherein the transparent cover 330, the first substrate 100 and the second substrate 200 are stacked in sequence. The light-condensing portion 400 is disposed on one side of the transparent cover plate 330 facing the first substrate 100 and the second substrate 200, at least a portion of a projection of the light-condensing portion 400 is located in a projection of the transparent region X in a direction perpendicular to the transparent cover plate 330, one side of the light-condensing portion 400 facing away from the transparent cover plate 330 has a light-emitting surface 420, and a protrusion is disposed on the light-emitting surface 420, that is, the light-condensing portion 400 is equivalent to a convex lens. Specifically, the first substrate 100 and the second substrate 200 are both made of glass plates, and devices such as thin film transistors are provided on the second substrate 200. The polarizer 320 is disposed between the transparent cover 330 and the first substrate 100 to improve the optical performance of the display module, and meanwhile, the transparent cover 330 and the polarizer 320 may be connected by the optical adhesive 310, and the optical adhesive 310 has good transmittance, so that the optical performance of the display module is not affected.
When light propagates in the optical device 500, the dispersed light passes through the light-gathering portion 400, and the light-gathering portion 400 has a converging effect on the light, so that the dispersed light becomes parallel light (the light propagation direction is shown as Z in fig. 4), the waste of the light is reduced, the light entering the optical device 500 is increased, and the working performance of the optical device 500 is improved.
Specifically, the light-gathering portion 400 may be disposed between the transparent cover plate 330 and the optical adhesive 310, or the light-gathering portion 400 may also be disposed between the optical adhesive 310 and the polarizer 320, or the light-gathering portion 400 may also be disposed between the first substrate 100 and the second substrate 200, however, when the light gathered by the light-gathering portion 400 passes through the first substrate 100 or the second substrate 200, or other layers, the light is scattered again, so that the light entering the optical device 500 is reduced, and in order to solve the problem, in another embodiment, the light-gathering portion 400 is disposed on a side of the second substrate 200 away from the first substrate 100. At this time, the light is converged by the light converging portion 400 and then directly enters the optical device 500, thereby reducing the waste of the light and further improving the optical performance of the optical device 500. Specifically, the display module may be provided with a fixing portion for fixing the light-condensing portion 400.
When the light-condensing portion 400 and the second substrate 200 have a gap, when light passes through the second substrate 200, light near the edge of the light-transmitting area X does not pass through the light-condensing portion 400, thereby causing the reduction of light passing through the light-condensing portion 400, causing the waste of light, and causing the reduction of light entering the optical device 500. For this reason, in an alternative embodiment, a surface of the light-condensing portion 400 facing the second substrate 200 is a first surface 410, a surface of the second substrate 200 facing the light-condensing portion 400 is a second surface 210, and the first surface 410 is in contact with the second surface 210. At this time, there is no gap between the light-condensing portion 400 and the second substrate 200, so most of the light near the edge of the light-transmitting area X can enter the light-condensing portion 400, thereby improving the utilization rate of the light and further improving the light-condensing effect of the light-condensing portion 400.
In the above embodiment, the first surface 410 may have an arc-shaped structure, and at this time, the area of the contact surface between the light-gathering part 400 and the second surface 210 is small, which causes the light-gathering part 400 and the second substrate 200 to be connected loosely, thereby reducing the reliability of the display module. In an alternative embodiment, the first surface 410 is a plane, and the first surface 410 is attached to the second surface 210. In this structure, the first surface 410 is a plane, and thus can be directly attached to the second surface 210 of the second substrate 200, so that the area of the contact surface between the light-gathering part 400 and the second substrate 200 is large, and the light-gathering part 400 and the second substrate 200 are connected more firmly, thereby further improving the reliability of the display module. Alternatively, the light-condensing portion 400 may be directly disposed on the second surface 210 of the second substrate 200 by means of bonding or the like. Specifically, the light condensing portion 400 may employ a Microlens (micro lens).
In order to further improve the light condensing effect of the light condensing part 400, in a preferred embodiment, the number of the protrusions of the light condensing part 400 may be multiple, the protrusions have arc-shaped surfaces, and the arc-shaped surfaces of the multiple protrusions are arranged in a direction parallel to the transparent cover plate 330. At this time, the projection area of the light-condensing portion 400 occupies the projection area of the light-transmitting region X, so that the region in the light-transmitting region X where light can be condensed is increased, the light-condensing effect of the display module is improved, and the working performance of the optical device 500 is further improved.
In the above embodiment, there may be a gap between adjacent protrusions, and at this time, light passes through the gap, and the gap cannot play a role of converging light, resulting in a waste of part of light. At this time, there is no space between adjacent protrusions, so that light is not wasted, and the amount of light entering the optical device 500 is further increased.
In order to further increase the light-gathering area and at the same time make the area for arranging the light-gathering part 400 smaller, in an alternative embodiment, in the direction perpendicular to the light-transmitting cover plate 330, a plurality of protrusions are all located in the projection of the light-transmitting region X, and the projection profile of the plurality of protrusions coincides with the projection profile of the light-transmitting region X. At this moment, the projection of the light condensing part 400 is only arranged in the projection of the light transmitting area X, and the projection area of the light condensing parts 400 is basically equal to that of the light transmitting area X, so that the light condensing area can be increased, the functions of other areas of the display module can not be influenced, meanwhile, the number of the protrusions can be relatively less, the manufacturing cost of the display module is reduced, and the good balance between the light condensing effect and the product cost is achieved.
The display module may be an OLED (Organic Light-Emitting Diode) display module, and the display module further includes a Light-Emitting layer 700, wherein the Light-Emitting layer 700 is disposed between the first substrate 100 and the second substrate 200. In order to improve the light utilization efficiency of the display module, in an alternative embodiment, the display module further includes a reflective electrode disposed on a side of the light-emitting layer 700 facing the second substrate 200. At this time, the reflective electrode can reflect a portion of the light emitted from the light emitting layer 700, so that the light can be sufficiently utilized, thereby improving the utilization rate of the light.
Of course, the display module may also be a liquid crystal display module, and at this time, liquid crystal is filled between the first substrate 100 and the second substrate 200, and the display module may also be provided with a backlight module.
In order to prevent the light leakage at the edge of the light-transmitting region X and affect the performance of the optical device 500, in an alternative embodiment, the display module further includes a light-shielding portion 600, the light-shielding portion 600 is disposed on a side of the second substrate 200 away from the first substrate 100, and the light-shielding portion 600 is disposed around the light-collecting portion 400. At this time, the light shielding portion 600 can cover the edge position of the light transmission region X, thereby preventing stray light from entering the optical device 500, and further improving the performance of the optical device 500. In order to better prevent light leakage at the edge of the light-transmitting region X, the light-shielding portion 600 may be attached to the second substrate 200, if the light-focusing portion 400 is disposed outside the light-shielding portion 600, a portion of light passing through the second substrate 200 may be blocked by the light-shielding portion 600, so that the portion of light may not enter the optical device 500, causing light waste, and therefore when the light-focusing portion 400 is located inside the light-shielding portion 600, the light-shielding portion 600 may not block the propagation of light, thereby further improving the working performance of the optical device 500. Further, the light-gathering part 400 may be disposed on a surface of the second substrate 200 away from the first substrate 100, so that the light utilization rate is higher.
Specifically, the light shielding portion 600 may be an annular structure, and a center of the light shielding portion 600 coincides with a center of the light transmitting area X, so that when light enters the optical device 500, the light is not shielded by the light shielding portion 600, and thus, more light is received by the optical device 500. The light shielding portion 600 may be made of foam or other light shielding materials, which is not limited herein.
The embodiment of the invention also discloses electronic equipment which is provided with the display module in any embodiment. The electronic device further includes an optical device 500, the optical device 500 and the first substrate 100 are respectively disposed on two sides of the second substrate 200, and the light-transmitting region X is disposed opposite to the optical device 500. The optical device 500 is installed below the display module, and thus does not occupy an excessive display area, thereby making the screen of the electronic device larger. Specifically, the optical device 500 may include a lens 510, a filter 520, a light sensing chip 530, a circuit board 540, and a support 550, where the support 550 provides a mounting space for the components of the optical device 500, the light sensing chip 530 is disposed between the filter 520 and the circuit board 540, and is connected to both the filter 520 and the circuit board 540, and at this time, light enters from the lens 510, passes through the filter 520, and enters the light sensing chip 530. The photo sensor chip 530 may be a CMOS (Complementary Metal Oxide Semiconductor) imaging chip.
Specifically, the optical device 500 may be a fingerprint module, which may be a photoelectric fingerprint module. When light emitted by the display module (for example, light emitted by the light emitting layer 700) reaches the transparent cover plate 330, the light is refracted back by the finger 800 of the user, and then passes through the first substrate 100, the second substrate 200, the light condensing portion 400 and other structures (the light propagation direction is shown as Y in fig. 3), and the light enters the fingerprint module, so as to realize the fingerprint identification function.
The electronic device disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader or a wearable device. Of course, the electronic device may also be other devices, and the embodiment of the present invention is not limited thereto.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
