Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present application. As shown in fig. 1, the display panel 10 includes a driving substrate 12 and a plurality of light emitting elements 14. The light emitting element 14 is disposed on the driving substrate 12 and electrically connected to the driving substrate 12. The light emitting element 14 emits light under the driving of the driving substrate 12 to display an image.
The light emitting element 14 is a mini LED (mini LED) or a micro LED (micro LED). Wherein the pitch of two adjacent light emitting elements 14 is not greater than 50 micrometers (e.g., 45 micrometers, 48 micrometers, 50 micrometers).
In the display panel of the embodiment of the application, the distance between two adjacent light emitting elements is not greater than 50 micrometers, so that the size of the display panel can be very small (for example, as small as less than 1cm × 1cm of a rectangular screen), and the use scene of the light emitting elements (mini light emitting diodes or micro light emitting diodes) with the micro size is widened. For example, the small-sized display panel can be applied to smart wearable devices, such as AR glasses, smart watches, and the like, and through bluetooth or other transmission, a user can define an image displayed on the display panel according to personal needs. Alternatively, the small-sized display panel can be applied to a headset as a display screen of the headset, and a user can define an image displayed on the display screen of the headset according to personal requirements. Or, the small-sized display panel can be applied to a keyboard to be used as a keycap, and a user can change images displayed on the keycap according to personal requirements.
It can be understood that the display panel of the embodiment of the present application can also be used in notebook computers, mobile phones, tablet computers or advertisement signs, etc., with a large size (e.g., a rectangular screen as large as 20cm × 20 cm). Because the display panel of the embodiment of the application adopts the mini LED or the micro LED as the display pixel point, the basic unit of imaging is provided, and image display is realized, and the display panel has the advantages of high brightness, wide color gamut, high contrast, high-speed response, low power consumption, long service life and the like.
In some embodiments, the light emitting elements 14 are micro LEDs, which refers to LEDs having a die size of less than 100 microns. In other embodiments, the light emitting elements 14 are mini LEDs. mini LEDs, also known as sub-millimeter LEDs, are sized between conventional LEDs and micro LEDs, typically meaning LEDs with a die size of approximately 100 to 200 microns.
In some embodiments, the display panel 10 includes light emitting elements 14 that emit different colors of light. For example, the light emitting elements 14 emitting different colors of light include a red-emitting LED142, a green-emitting LED144, and a blue-emitting LED146. One of the red light emitting LEDs 142, two green light emitting LEDs 144, and one blue light emitting LED146 constitute one pixel P. The display panel 10 includes a plurality of pixels P arranged in an array, so that the display panel 10 realizes a color picture display. In other embodiments, the light emitting elements 14 emitting light of different colors are not limited to the above three colors, and the number of light emitting elements 14 in each pixel P and the light emission type of the light emitting elements 14 are not limited thereto.
In some embodiments, the driving substrate 12 is flexible and inflexible, such as a Printed Circuit Board (PCB). The driving substrate 12 includes, for example, a base layer (not shown) that is flexible and inflexible, and a driving circuit layer (not shown) on the base layer. The light emitting elements 14 are electrically connected to the driving circuit layer to emit light under the driving of the driving circuit layer.
In the embodiment shown in fig. 1, the driving substrate 12 includes an upper hemisphere 122 and a lower hemisphere 124 that are snap-fit. A part of the light emitting elements 14 is located on the outer surface of the upper hemisphere 122, and another part of the light emitting elements 14 is located on the outer surface of the lower hemisphere 124. That is, the display panel 10 includes two hemispheres, and the display panel 10 is a hollow spherical housing as a whole in a snap-fit state. The display panel 10 is two hollow hemispherical cases in an open state.
In some embodiments, the method of manufacturing the display panel 10 includes providing the driving substrate 12 that is curved and inflexible, and then soldering the plurality of light emitting elements 14 on the outer surface of the driving substrate 12.
In the embodiment shown in fig. 1, the display panel 10 is described as an example of a sphere in which the engagement state is complete. In other embodiments, the display panel 10 may be a half sphere (i.e., the driving substrate 12 is a hollow hemisphere, and the plurality of light emitting elements 14 are located on an outer surface of the hemisphere), or the display panel 10 may have a curved surface structure, which may be a regular arc structure or an irregular structure. For example, the drive base plate 12 includes a portion that is arcuate, wherein the radius of curvature of the arc of the arcuate portion is 0.5 cm to 100 cm (e.g., 0.5 cm to 1cm, 1cm to 10 cm, 10 cm to 20cm, 20 to 50 cm, 50 cm to 100 cm).
In the embodiment of the present application, the distance between the adjacent light emitting elements 14 may not be greater than 50 micrometers, so that the size of the display panel 10 may be very small, and still have high resolution, and the transfer and welding of the light emitting elements 14 are realized on the curved driving substrate 12, so that the display panel 10 may not only realize the display of different sizes, but also realize the curved display, and further widen the usage scenario of the light emitting elements 14 (mini light emitting diodes or micro light emitting diodes) with small size.
Specifically, when the size of the display panel 10 is small, for example, the radius of curvature of the arc of the driving substrate 12 is about 0.5 cm, it is used for a button of a headphone or a joystick, for example. When the size of the display panel 10 is relatively large, for example, the radius of curvature of the arc of the driving substrate 12 is several tens cm to 100 cm, it is used for a signboard, for example.
Fig. 2 is a schematic structural diagram of a touch panel according to an embodiment of the present disclosure. As shown in fig. 2, the touch panel 20 includes a substrate 22 and a touch sensing layer 24 disposed on a surface of the substrate 22. The substrate 22 is flexible and inflexible, and the touch sensing layer 24 is directly formed on the surface of the substrate 22.
Specifically, the material of the substrate 22 is, for example, polycarbonate (PC). In other embodiments, the substrate 22 may be other non-flexible plastics. In the present embodiment, "inflexible" means not bendable at normal temperature (or normal use), but not under heating and/or pressure.
In some embodiments, the touch panel 20 is combined with the display panel 10 to form a structure with a touch display function. The touch panel 20 is stacked on the display panel 10, and the substrate 22 is a surface (may also be referred to as a cover plate) directly contacted by a user touch operation, in which case the substrate 22 is transparent.
In the embodiment of the present disclosure, the phrase "the substrate is curved and inflexible, and the touch sensing layer is directly formed on the surface of the substrate" means that the touch sensing layer 24 is directly formed on the curved surface of the substrate 22, for example, a conductive material layer (not shown) may be formed on the curved surface of the substrate 22 by sputtering, etc., and then the conductive material layer is processed by etching (e.g., photolithography), etc., so as to form the touch sensing layer 24. That is, the touch sensing layer 24 is not formed on another carrier substrate and then attached to the base material 22 (hereinafter referred to as "the first method"), or the touch sensing layer 24 is formed on the planar base material 22 and then the base material 22 with the touch sensing layer 24 is bent (hereinafter referred to as "the second method").
In the touch panel of the embodiment of the application, the touch sensing layer is directly formed on the curved surface of the substrate, so that compared with the first mode, the steps of attaching are reduced, the thickness of an adhesive layer of the attaching is reduced, and the manufacturing process is simplified; compared with the second mode, the problem of tensile strength of the substrate in the bending step and the problem of breakage of the touch electrode and/or the lead included in the touch sensing layer in the bending step do not need to be considered, so that the yield of products is improved. Further, because the touch panel in the embodiment of the present application has the advantages described above, when the touch panel is combined with the display panel in the embodiment of the present application, the application scenario of the display panel in the embodiment of the present application can be further expanded, so that the display panel in the embodiment of the present application is applied to a curved touch display device.
In some embodiments, in order to improve the light transmittance of the touch panel 20, the conductive material in the touch sensing layer 24 is, for example, a metal mesh or indium tin oxide. The touch sensing layer 24 can be a single-layer self-capacitance touch layer (not shown) including a plurality of self-capacitance touch electrodes. When touch occurs, capacitance sensing signals corresponding to the vicinity of the touch point are different, the capacitance sensing signals are received and processed, and then the relative position of the touch point can be obtained through conversion. Alternatively, the touch sensing layer 24 is a mutual capacitance type touch sensing structure (not shown), and the mutual capacitance type touch sensing structure includes a plurality of touch driving electrodes and a plurality of touch sensing electrodes, when a touch occurs, capacitive coupling between the driving electrodes and the sensing electrodes corresponding to the vicinity of the touch point will be affected, so that a sensing signal (e.g. a voltage value) related to mutual capacitance will be changed, and then the coordinates of each touch point can be calculated.
In the embodiment shown in fig. 2, the substrate 22 includes another upper hemisphere 222 and another lower hemisphere 224 that are snap-fit together. A portion of the touch sensing layer 24 is directly formed on an inner surface of the other upper hemisphere 222, and another portion of the touch sensing layer 24 is directly formed on an inner surface of the other upper hemisphere 222. That is, the touch panel 20 includes two hemispheres, and the touch panel 20 is a hollow spherical housing in a fastened state. The touch panel 20 is two hollow hemispherical shells in the open state. The method for manufacturing the touch panel 20 includes providing two curved and inflexible hemispherical substrates 22, and then directly forming touch sensing layers 24 on inner surfaces of the two hemispherical substrates 22, respectively.
In the embodiment shown in fig. 2, the engagement state of the touch panel 20 is taken as a complete sphere as an example for description. In other embodiments, the touch panel 20 may be a semi-sphere (i.e., the substrate 22 is a hollow hemisphere, and the touch sensing layer 24 is located on the inner surface of the hemisphere), or the touch panel 20 may have other forms with a curved surface structure, which may be a regular arc structure or an irregular structure. In addition, the touch sensing layer 24 in fig. 2 is illustrated by a plurality of polygons, which does not mean the arrangement of the real pattern of the electrodes in the touch sensing layer 24.
Fig. 3 is a schematic structural diagram of an electronic device according to an embodiment of the present application. As shown in fig. 3, the electronic device 100a includes a display panel 10 and a touch panel 20. The touch panel 20 and the display panel 10 are stacked, the bending state of the touch panel 20 matches the bending state of the display panel 10, and the substrate 22 of the touch panel 20 is used as a cover plate for direct touch operation by a user. In the electronic device 100a, the base 22, the touch sensing layer 24, the light emitting elements 14, and the driving substrate 12 are sequentially stacked in the upper and lower hemispheres. The touch sensing layer 24 and the plurality of light emitting elements 14 are disposed facing each other and between the base 22 and the driving substrate 12. The touch sensing layer 24 is insulated from the plurality of light emitting elements 14. For example, a transparent Adhesive layer, such as Optically Clear Adhesive (OCA), is disposed between the touch sensing layer 24 and the light emitting elements 14 to adhere the touch panel 20 and the display panel 10.
The electronic device of the embodiment of the present application includes the curved touch panel 20 and the curved display panel 10, so that the electronic device has both the curved display function and the touch function.
Different application scenarios of the electronic device 100a shown in fig. 3 are specifically described below with reference to fig. 4A to 4E.
Specifically, the electronic device 100a shown in FIG. 3 can be used in conjunction with the gamepad 200 as a variable context interaction device. As shown in fig. 4A, the upper and lower hemispheres of the electronic device 100a can be opened, so that the game pad 200 is placed in the spherical shell. The display panel 10 of the electronic device 100a can display the corresponding ball appearance according to the type of the ball game. For example, in fig. 4A, the ball game is a baseball game, and in this case, the image presented by the display panel 10 is a baseball; in fig. 4B, 4C, 4D and 4E, the ball games are a baokou ball game, a basketball game, a football game and a tennis game, respectively, in which case the images displayed on the display panel 10 are baokou ball, basketball, football and tennis. Understandably, the ball game is not limited to that shown in fig. 4A to 4E, but it may also be a bowling game or a golf game, for example.
It should be noted that the conventional ball game usually includes a game handle for a user to perform actions similar to real-life sports, such as throwing a baseball, throwing a bowling ball, shooting a basketball, and the like. In the embodiment of the present application, the display panel 10 of the electronic device 100a can change the corresponding spherical appearance according to the type of the ball game, and meanwhile, the user can put the gamepad 200 into the hollow spherical shell of the electronic device 100a, so as to convert the action of the gamepad 200 into the action of the spherical electronic device 100a, so that the ball game has more realistic sensation, and the user experience is improved.
In some embodiments, the touch panel 20 and the display panel 10 are both curved aspheric structures, and the touch display structure 30a formed by stacking the touch panel 20 and the display panel 10 is a curved aspheric structure. In this case, the touch display structure 30a can be applied to various mobile electronic devices.
Specifically, as shown in fig. 5, the electronic device 100b is an AR glasses, the touch display structure 30a is disposed on a temple of the AR glasses, the touch display structure 30a can have a certain radian with the temple, and a user can define the content displayed on the touch display structure 30a and the function that can be triggered by touching the touch display structure 30a through bluetooth or other transmission technologies. For example, when the user touches the touch display structure 30a, the function of the AR glasses to receive a call may be triggered, and the touch display structure 30a displays a call state.
As shown in fig. 6, the electronic device 100c is a smart watch, the touch display structure 30a is disposed on a watch band of the smart watch, the touch display structure 30a can have a certain complete arc (e.g., the curvature radius of the whole touch display structure 30a is about 3 cm) along with the watch band, and a user can define the content displayed on the touch display structure 30a and the function that can be triggered by touching the touch display structure 30a through bluetooth or other transmission technologies.
In addition, the above embodiment is described by taking the display panel 10 and the touch panel 20 as an example of a curved surface structure. In other embodiments, the display panel 10 and the touch panel 20 may also be of a planar structure. That is, the drive substrate 12 of the display panel 10 is flat, and the plurality of light-emitting elements 14 are positioned on the flat drive substrate 12. Each light emitting element 14 is a mini light emitting diode or a micro light emitting diode, and the pitch of adjacent light emitting elements 14 is not more than 50 micrometers. Due to the display panel of the embodiment of the application, the distance between two adjacent light emitting elements is not more than 50 micrometers, so that the size of the display panel can be small (for example, a rectangular screen smaller than 1cm × 1 cm), and the display panel can be used for a small-sized flat panel display to widen the use scene of a light emitting element (a mini light emitting diode or a micro light emitting diode) with a micro size.
Similarly, the substrate 22 of the touch panel 20 may also be a flat plate, and the touch sensing layer 24 is directly formed on the surface of the flat plate. The flat touch panel can be stacked with the display panel with the planar structure, so that the micro-sized light-emitting element (mini light-emitting diode or micro light-emitting diode) can realize a small-sized planar display function, a touch function can be realized, and the application scenes of the micro-sized light-emitting element (mini light-emitting diode or micro light-emitting diode) are further expanded.
Specifically, as shown in fig. 7, the electronic device 100d is a keyboard.
