[0031] Figure 1 A schematic diagram of a display panel is shown, only parts related to the present embodiment are shown for the convenience of description, and are described in detail as follows:

[0032] A display panel 10 includes a circuit board 100, light emitting units 210, sound emitting units 220 and a driving unit 300.

[0033] The sound emitting units 220 and the light emitting units 210 are arranged on the same surface of the circuit board 100; the driving unit 300 is electrically connected with the light emitting units 210 and the sound emitting units 220.

[0034] The sound emitting units 220 can be arranged in the gaps between the light emitting units 210, so that the sound emitting units 220 and the light emitting units 210 are arranged on the same surface of the circuit board 100. In the prior art, the sound emitting units 220 are usually arranged on the back surface of the display panel 10. In order to hear clear sound on the front surface of the display panel 10, a hole is usually opened on the display panel 10. However, the present embodiment does not need to open a hole on the circuit board 100 for arranging the sound emitting units 220, thereby improving the sensory experience of users.

[0035] The light emitting units 210 can be used to light up or turn off in response to a first driving signal, and the sound emitting units 220 can be used to emit sound in response to a second driving signal. The driving unit 300 is connected with each light emitting unit 210 and each sound emitting unit 220, and the driving unit 300 can be used to provide the first driving signal and / or the second driving signal according to a control instruction.

[0036] The driving unit 300 can include a driving integrated circuit (IC), which can drive the light emitting units 210 and / or the sound emitting units 220 according to a control instruction input from outside. It can be understood that the functions and quantity of the driving IC can be set according to actual needs.

[0037] In some embodiments, the sound emitting units 220 and the light emitting units 210 can be arranged on the front surface of the circuit board 100, and the driving unit 300 can be arranged on the front surface or the back surface of the circuit board 100.

[0038] In some embodiments, the sound emitting units 220 and the light emitting units 210 can be directly arranged on the circuit board 100 through a Chip on Board (COB) packaging process, or indirectly arranged on the circuit board 100 through other packaging processes.

[0039] In an embodiment, as Figure 1 , Figure 2As shown, the display panel 10 includes a pixel module 200, the pixel module 200 includes a substrate 230 and a packaging layer, the substrate 230 is arranged on the circuit board 100, the light emitting unit 210 and the sound emitting unit 220 are arranged on the substrate 230, and the packaging layer is arranged on the substrate 230 and covers the light emitting unit 210 and the sound emitting unit 220. The light emitting unit 210 and the sound emitting unit 220 are electrically connected to the circuit board 100 through the substrate 230.

[0040] It should be noted that, in general, the area ratio of the light emitting unit 210 is less than 1 / 10 of the entire pixel module 200. The size of the light emitting unit 210 is much smaller than the spacing between the light emitting units 210 of each pixel module 200, and therefore, there is sufficient space on the substrate 230 to arrange the sound emitting unit 220.

[0041] It can be understood that a plurality of pixel modules 200 can be arranged on the display panel 10, and the pixel modules 200 can be arranged on the display panel 10 according to actual needs. When the display panel 10 displays a certain picture, one pixel module 200 can correspond to one pixel of the picture, and a complete picture can be displayed through a plurality of pixel modules 200.

[0042] Specifically, the pixel module 200 can be constructed by a discrete device process (MLED in Package; MIP), and the light emitting unit 210 and the sound emitting unit 220 are indirectly arranged on the circuit board 100.

[0043] It should be noted that in the pixel module 200, the area of the light emitting unit 210 is generally less than 1 / 10 of the entire pixel module 200, and the sound emitting unit 220 and the light emitting unit 210 can be arranged on the same substrate 230 by the MIP process.

[0044] In some embodiments, the light emitting unit 210 and the sound emitting unit 220 can be arranged on the same substrate 230 by the MIP process, as shown in Figure 2 As shown, the substrate 230 has a first surface and a second surface opposite to the first surface.

[0045] The sound emitting unit 220 is arranged on the first surface of the substrate 230 through a corresponding first bonding conductive layer 240.

[0046] The light emitting unit 210 and the sound emitting unit 220 are arranged on the first surface of the substrate 230 through a corresponding second bonding conductive layer 250. The second surface of the substrate 230 is used to be fixed on the circuit board 100. The sound emitting unit 220 and the light emitting unit 210 can be arranged on the first surface of the substrate 230 respectively, and the specific arrangement manner of the sound emitting unit 220 and the light emitting unit 210 is not limited, for example, the two can be arranged side by side or staggered, can be adjacent to each other, or can be spaced apart by a certain distance.

[0047] Alternatively, the light-emitting unit 210 and the sound-emitting unit 220 are stacked on the first surface of the substrate 230.

[0048] It is understandable that when the light-emitting unit 210 is lit in response to the first driving signal, it can emit light of the corresponding color according to the requirements of the first driving signal and its own light-emitting conditions.

[0049] In this embodiment, by directly integrating the sound-emitting unit 220 and the light-emitting unit 210 into a single pixel module 200, the single pixel module 200 can realize functions other than light emission, thereby making full use of the surface of the upper substrate 230 other than the light-emitting unit 210.

[0050] Since this application utilizes the non-light-emitting area on the substrate 230, it makes full use of the surface space of the substrate 230 while ensuring the display effect, and can provide users with richer content and more effective real-time interaction.

[0051] It should be noted that the pixel module 200 can be packaged in two ways. One is a co-packaged method, in which the light-emitting unit 210 and the sound-emitting unit 220 are connected to the substrate 230 through a single bonding process. The other is a separate bonding method, in which each light-emitting unit 210 and each sound-emitting unit 220 is individually bonded to the substrate 230 and then packaged as a whole to form a pixel module 200.

[0052] Specifically, the encapsulation layer can be an encapsulating adhesive or an encapsulating film. For example, the light-emitting unit 210 and / or the sound-emitting unit 220 can be encapsulated by applying and curing the encapsulating adhesive, or by attaching the encapsulating film to the substrate 230 to encapsulate the light-emitting unit 210 and / or the sound-emitting unit 220. The main components of the encapsulating adhesive and the encapsulating film can be epoxy resin, silicone resin, etc.

[0053] Using a thin film for encapsulation can reduce the overall package size, making it easier to install and use the pixel module 200 and improving its practicality.

[0054] In one embodiment, such as Figure 3 As shown, the first surface of the sound-emitting unit 220 is disposed on the first surface of the substrate 230 through a corresponding first bonding conductive layer 240; the light-emitting unit 210 is disposed on the second surface of the sound-emitting unit 220 away from the substrate 230.

[0055] It is understood that the light-emitting unit 210 can be stacked with the sound-emitting unit 220 to further reduce the space occupied on the first surface of the substrate 230.

[0056] In one embodiment, such as Figure 4As shown, the sound generating unit 220 can also be disposed on the light emitting unit 210. Specifically, the sound generating unit 220 can be disposed on the light emitting unit 210 according to actual conditions, for example, in the case of light transmission of the sound generating unit 220, or the sound generating unit 220 can be disposed on the light emitting unit 210 with a certain gap or offset from the light emitting unit 210 for light transmission.

[0057] In an embodiment, the material of the first and second bonding conductive layers 240 and 250 includes conductive glue or conductive metal.

[0058] It can be understood that a suitable bonding process can be selected according to actual needs to bond the light emitting unit 210 and the sound generating unit 220. For example, a suitable bonding process can be selected according to the structure of a specific device in the light emitting unit 210 or the sound generating unit 220 and the requirements of the specific device for bonding. The bonding process that can be used includes die bonding process, metal bonding process, and conductive glue process.

[0059] In some embodiments, the size of the single pixel module 200 is 1 mm x 1 mm.

[0060] In an embodiment, the driving unit 300 is disposed on the substrate 230, and the driving unit 300 is electrically connected to the connection circuit through the substrate 230.

[0061] It can be understood that the driving unit 300 can be disposed on the substrate 230 by the MIP process, like the sound generating unit 220.

[0062] It can be understood that in the embodiment, the first driving signal can be a driving voltage / current, and the second driving signal can be a data signal. Since the driving unit 300 is essential for the light emitting unit 210, by integrating the driving unit 300 on the first surface of the substrate 230, the driving unit 300 can be disposed without additional space, realizing miniaturization of the overall circuit and improving the integration level of the display panel 10.

[0063] In some embodiments, the light emitting unit 210 and the driving unit 300 are disposed in layers to further reduce the space occupation of the first surface of the substrate 230.

[0064] In an embodiment, the display panel 10 further includes at least one functional device, and the functional device is disposed on the substrate 230. The functional device includes one or more of an infrared sensor, a camera unit, a sound sensor, a temperature sensor, a humidity sensor, a light intensity sensor, and a gas sensor. It can be understood that the functional device can be disposed on the substrate 230 by the MIP process, like the sound generating unit 220.

[0065] The pixel module 200 can include a plurality of functional devices of different types.

[0066] The infrared sensor can be used for infrared touch detection. When the pixel module 200 with the infrared sensor is applied to the display panel 10, the display panel 10 can collect touch through the infrared sensor, thereby realizing touch operation of the display panel 10. The infrared sensor can be a Time of Flight (ToF) infrared sensor. In some embodiments, the second driving signal can include a voltage signal for driving the infrared sensor to work.

[0067] The camera unit can collect images in a corresponding direction, and then generate and output a corresponding video signal. When the pixel module 200 with the camera unit is applied to the display panel 10, the camera unit can replace a front independent camera to take pictures, thereby ensuring the integrity of the display panel 10 and improving the sensory experience of the user. The camera unit can be a Charge-coupled Device (CCD) or a Complementary Metal-Oxide-Semiconductor (CMOS). In some embodiments, the second driving signal can include a voltage signal for driving the camera unit to work.

[0068] The sound sensor can collect sound. When the pixel module 200 with the sound sensor is applied to the display panel 10, the sound sensor can replace a microphone to collect sound around the display panel 10. In some embodiments, the second driving signal can include a voltage signal for driving the camera unit to work.

[0069] The temperature sensor can detect temperature. When the pixel module 200 with the temperature sensor is applied to the display panel 10, the temperature sensor can control the brightness, color, etc. of the light emitting unit 210 according to the ambient temperature and the temperature of the display panel 10. For example, the brightness of the light emitting unit 210 can be reduced when the temperature of the pixel module 200 is too high, and the color and brightness of the light emitting unit 210 can be changed when the ambient temperature is low.

[0070] The humidity sensor can detect the humidity of air. When the pixel module 200 with the humidity sensor is applied to the display panel 10, the humidity sensor can monitor the humidity of air around the display panel 10. In some embodiments, the second driving signal can include a voltage signal for driving the humidity sensor to work.

[0071] The light intensity sensor can sense the light intensity. When the pixel module 200 using the light intensity sensor is applied to the display panel 10, the brightness of the display panel 10 can be adjusted according to the light intensity (ambient brightness) in front of the display panel 10. For example, the brightness of the display panel 10 can be reduced when the light intensity in front of the display panel 10 is low, so as to realize vision protection in a dark environment.

[0072] The gas sensor can identify a specified substance in the air. When the pixel module 200 using the gas sensor is applied to the display panel 10, the air around the display panel 10 can be monitored. When the quality of the air deteriorates and the concentration of a certain substance in the air increases, the gas sensor can detect this situation in time, so that a timely response can be made. In some embodiments, the second driving signal can include a voltage signal for driving the gas sensor to work.

[0073] In an embodiment, the plurality of pixel modules 200 are arranged in an array. For example, the pixel modules 200 can be arranged in a rectangular array.

[0074] Specifically, the arrangement of the pixel modules 200 can be selected according to actual needs, and the present embodiment does not limit the arrangement of the pixel modules 200.

[0075] It can be understood that the display panel 10 can display a corresponding image by individually controlling the light emitted by each pixel module 200. The functional devices of the pixel modules 200 in one display panel 10 can be different from each other, and the corresponding pixel module 200 can be selected according to the functional requirements of the display panel 10.

[0076] In an embodiment, as shown in Figure 5 The display panel 10 further includes a light-transmitting cover 400, which is disposed on the circuit board 100. The light-transmitting cover 400 is provided with a hole 410 corresponding to the pixel module 200, and the pixel module 200 passes through the hole 410. The shape of the hole 410 is adapted to the shape of the pixel module 200, for example, the hole 410 can be circular, rectangular, etc.

[0077] It can be understood that the hole 410 can cooperate with the sound emitting unit 220, and the sound emitting effect of the sound emitting unit 220 can be improved.

[0078] In an embodiment, as shown in Figure 6 The light emitting unit 210 includes at least one LED chip, and the LED chip includes at least one of a red LED chip 211, a green LED chip 212, a blue LED chip 213, and an LED chip of another color.

[0079] Red LED chip 211 is used to emit red light, green LED chip 212 is used to emit green light, blue LED chip 213 is used to emit blue light, and other colored LED chips can be white LED chips, yellow LED chips, etc.

[0080] It is understandable that a light-emitting unit 210 may include only one color of LED chip or multiple colors of LED chip.

[0081] For example, such as Figure 6 As shown, a light-emitting unit 210 may include a red LED chip 211, a green LED chip 212 and a blue LED chip 213.

[0082] A red LED chip 211, a green LED chip 212, and a blue LED chip 213 are disposed on the substrate 230 along a first direction parallel to the first surface of the substrate 230. Alternatively, the orientation of the three chips can be unrestricted. Theoretically, the combination of the red LED chip 211, green LED chip 212, and blue LED chip 213 can enable the light-emitting unit 210 to emit light of any color.

[0083] In one embodiment, the connection circuit includes multiple switching switches. Figure 7 The diagram shows a first switching switch Q1, a second switching switch Q2, a third switching switch Q3, and a fourth switching switch Q4, and multiple first scan lines 110. Each first scan line 110 is electrically connected to at least one end of a switching switch, and each light-emitting unit 210 is electrically connected to at least one first scan line 110. The control terminal of the switching switch is electrically connected to the drive unit 300. Alternatively, the connection circuit can omit the switching switches and instead use first scan lines, with the switching switches integrated into the drive unit 300, and the first scan lines electrically connecting the light-emitting unit 210 and the drive unit 300.

[0084] It should be noted that each light-emitting unit 210 can correspond one-to-one with a first scan line 110, and each light-emitting unit 210 can be connected to its corresponding first scan line 110. The first scan line 110 can extend along a first direction, and each first scan line 110 can be arranged in parallel along a second direction. Multiple light-emitting units 210 in a pixel module 200 can be arranged along the first direction. The first direction and the second direction are perpendicular to each other.

[0085] It is understandable that when the switch is turned off, the corresponding scan line can stop supplying power to the corresponding unit.

[0086] In one embodiment, such as Figure 7As shown, the connection circuit further comprises a plurality of second scan lines 120, one end of at least one of the switching switches is electrically connected to one of the second scan lines 120, and each of the sound generating units 220 and each of the functional devices is electrically connected to at least one of the second scan lines 120.

[0087] It should be noted that the sound generating units 220 and the functional devices can correspond to the second scan lines 120 one by one, and the sound generating units 220 and the functional devices can be connected to the corresponding second scan lines 120. The second scan lines 120 can extend along a first direction, and each of the second scan lines 120 can be arranged in parallel along a second direction.

[0088] In some embodiments, only the first scan lines 110 supply power to the corresponding light emitting units 210 or only the second scan lines 120 supply power to the corresponding sound generating units 220 and functional devices at the same time, so as to avoid mutual influence between the light emitting units 210 and the functional devices / sound generating units 220.

[0089] In some embodiments, the same first scan line 110 can supply power to different pixel modules 200, and the same second scan line 120 can supply power to different pixel modules 200.

[0090] In an embodiment, the size of a single pixel module 200 is 1 mm x 1 mm. The edge spacing between the pixel module 200 and the adjacent pixel module 200 or other devices is 0.8 mm, and the center spacing between the adjacent two pixel modules 200 is 1.8 mm. It can be understood that the size of a single pixel module 200 can also be other sizes, for example, 0.25 mm x 0.25 mm, and the center spacing between the adjacent two pixel modules 200 can also be other sizes, for example, 1.25 mm, which is not limited in particular.

[0091] In an embodiment, as shown in FIG. 6, the display panel 10 can also use the pixel module 200 and the traditional pixel structure 600 in a mixed manner, so that the pixel module 200 and the pixel module 200 are separated by at least one traditional pixel structure 600. By using the pixel module 200 and the traditional pixel structure 600 in a mixed manner, the corresponding functions can be realized by the pixel module 200 while the manufacturing cost is reduced. Figure 8 In an embodiment, as shown in FIG. 6, the display panel 10 can also use the pixel module 200 and the traditional pixel structure 600 in a mixed manner, so that the pixel module 200 and the pixel module 200 are separated by at least one traditional pixel structure 600. By using the pixel module 200 and the traditional pixel structure 600 in a mixed manner, the corresponding functions can be realized by the pixel module 200 while the manufacturing cost is reduced.

[0092] Figure 9 In an embodiment, as shown in FIG. 6, the display panel 10 can also use the pixel module 200 and the traditional pixel structure 600 in a mixed manner, so that the pixel module 200 and the pixel module 200 are separated by at least one traditional pixel structure 600. By using the pixel module 200 and the traditional pixel structure 600 in a mixed manner, the corresponding functions can be realized by the pixel module 200 while the manufacturing cost is reduced.

[0093] In an embodiment, as shown in FIG. 6, the display panel 10 can also use the pixel module 200 and the traditional pixel structure 600 in a mixed manner, so that the pixel module 200 and the pixel module 200 are separated by at least one traditional pixel structure 600. By using the pixel module 200 and the traditional pixel structure 600 in a mixed manner, the corresponding functions can be realized by the pixel module 200 while the manufacturing cost is reduced. Figure 10 In an embodiment, as shown in FIG. 6, the display panel 10 can also use the pixel module 200 and the traditional pixel structure 600 in a mixed manner, so that the pixel module 200 and the pixel module 200 are separated by at least one traditional pixel structure 600. By using the pixel module 200 and the traditional pixel structure 600 in a mixed manner, the corresponding functions can be realized by the pixel module 200 while the manufacturing cost is reduced.​

[0094] By arranging the light-emitting unit 210 and the sound-emitting unit 220 adjacent to each other, it is possible to ensure that the display panel 10 emits light evenly, thus ensuring the display effect of the display panel 10, and avoiding the sound-emitting unit 220 being too concentrated or too sparse, which would affect the display effect.

[0095] Figure 11 A schematic diagram of the structure of a display unit according to an embodiment of this application is shown. For ease of explanation, only the parts related to this embodiment are shown, and the details are as follows:

[0096] The display unit 20 includes a support frame 21, a control module 22, a power module 23, and at least one display panel 10 as described in any of the above embodiments. The display panel 10 is mounted on the support frame 21, and the support frame 21 is used to support each display panel 10.

[0097] For example, such as Figure 11 As shown, the display unit 20 includes four display panels 10, which are arranged in a grid pattern.

[0098] like Figure 12 As shown, the control module 22 is electrically connected to the display panel 10, and is used to provide control commands to the display panel 10. The power module 23 is electrically connected to the control module 22, and the control module 22 is also used to control the power module 23 to supply power to the light-emitting unit 210, the sound-emitting unit 220, the driving unit 300, and the functional devices. The control module 22 may include control units such as a control chip and a processor. The control module 22 can automatically issue control commands, or it can generate and output corresponding control commands based on received signals.
