Description

[0002] With the rapid development of display devices, OLED (Organic Light-Emitting Diode) display panels are becoming more and more popular due to their better color and picture display effects. OLED display panels can rely on each pixel module to emit light independently, thus forming display effects of different sizes by one or more pixel modules.

DETAILED DESCRIPTION

[0026] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Figure 1 is a schematic diagram of a first embodiment of a display panel of the present application, Figure 2 A schematic diagram of a fixing structure in a first embodiment of a display panel of the present application; Figure 3 A schematic diagram of a substrate in a first embodiment of a display panel of the present application; Figure 4 A schematic diagram of a blocking structure in a first embodiment of a display panel of the present application; Figure 5 Schematic diagram of a pixel module in a first embodiment of a display panel of the present application; Figures 1 to 5 As shown, the embodiment of the present application discloses a display panel 100, including a substrate 110, a blocking structure 120, a fixing structure 130 and a plurality of pixel modules 150, wherein the pixel modules 150 are used for luminous display, and a plurality of mounting areas 160 are divided on the substrate 110, wherein the mounting areas 160 are used for mounting the pixel modules 150; the fixing structure 130 is arranged between two adjacent mounting areas 160; one side of the fixing structure 130 is connected to the blocking structure 120, and the other side is connected to the substrate 110; when the pixel module 150 is installed, the fixing structure 130 lifts the blocking structure 120 relative to the substrate 110 by a preset height H, and the blocking structure 120 avoids the pixel module 150 above the blocking structure 120, and shields the pixel module 150 between the blocking structure 120 and the substrate 110.

[0028] The present application sets a blocking structure 120 and a fixing structure 130 on the substrate 110 of the display panel 100. When a plurality of pixel modules 150 need to be installed on the substrate 110, the fixing structure 130 is first used to lift the blocking structure 120 relative to the substrate 110 by a preset height H. The preset height H to which the blocking structure 120 is lifted by the fixing structure 130 controls the size of the space between the blocking structure 120 and the substrate 110 for assembling the pixel modules 150. Then, the plurality of pixel modules 150 are tilted downward from the top of the blocking structure 120. 150 will pass through the blocking structure 120 and fall onto the substrate 110. Since part of the pixel module 150 bounces up after falling onto the substrate 110, the blocking structure 120 will block the bounced-up pixel module 150, so that the pixel module 150 can only move in the space formed between the blocking structure 120 and the substrate 110, and finally the pixel module 150 returns to the substrate 110 and falls into the installation area 160 for installation, which effectively prevents the pixel module 150 from falling outside the substrate 110 during the installation process, thereby improving the installation efficiency of the pixel module 150.

[0029] In the display panel 100 of the present application, each pixel module 150 can be used as a pixel of the display panel 100 for independent display; multiple sub-pixels on each pixel module 150 constitute a pixel, and the multiple sub-pixels include a red light-emitting unit R, a green light-emitting unit G, and a blue light-emitting unit B. That is, only one pixel unit is provided on each pixel module 150, and one pixel unit includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Any color can be displayed by adjusting different grayscale voltages through three sub-pixels of different colors. It is equivalent to that each pixel unit on the display panel 100 forms a module, and the display panel 100 is displayed through modular pixel modules 150 one by one.

[0030] Specifically, each pixel module 150 is provided with a pixel driving circuit 151, and the pixel driving circuit 151 drives the pixel module 150 to emit light and display; the pixel driving circuit 151 includes a communication module 152 and a control module 153, the communication module 152 is used to receive a data signal, and the control module 153 controls the pixel module 150 to emit light and display through the control module 153 according to the data signal; the pixel module 150 includes a substrate 154, and a light-emitting layer 155 and an encapsulation layer 156 arranged on the substrate 154 in sequence, a power receiving terminal 157 is arranged on the side of the substrate 154 away from the light-emitting layer 155, and a power supply terminal 158 is arranged in the substrate 110 corresponding to the power receiving terminal 157; the power supply terminal 158 provides an electrical signal to the power receiving terminal 157 to power the pixel driving circuit 151.

[0031] For example, when the signal transmission mode of the pixel module 150 is a wireless transmission mode, the power receiving end 157 includes a first coil, the power supply end 158 includes a second coil, and multiple power supply ends 158 are arranged one-to-one correspondingly to the power receiving ends 157 on the multiple pixel modules 150; the pixel module 150 is powered by wirelessly transmitting signals between the first coil and the second coil.

[0032] Specifically, the communication module 152 includes a wireless receiving module, which is used to receive external data signals and generate data control signals according to the external signals and transmit them to the control module 153. In this embodiment, the signal transmission method of the pixel module 150 can be a wireless transmission method, for example, a wireless transmitting module is set externally to cooperate with the wireless receiving module. Taking the wifi module as an example, it includes at least a plurality of wifi receiving modules and a wifi transmitting module. Each pixel module 150 is provided with at least one wifi receiving module. Each pixel module 150 adopts the WiFi module networking method to receive the above-mentioned external data signals through the wireless receiving module, thereby realizing the signal transmission of the pixel module 150 and controlling the pixel module 150 to emit light. Of course, in addition to the one-to-many method, the wireless transmission method can also set multiple wifi transmitting modules to transmit data in a one-to-one manner.

[0033] Of course, the signal transmission of the pixel module 150 can also adopt a contact signal transmission method. For example, exposed metal gaskets are respectively arranged at the bottom of the pixel module 150 and in the corresponding installation area 160. When the pixel module 150 is installed in the installation area 160, the corresponding power receiving end 157 contacts the power supply segment to achieve electrical connection. The above-mentioned data signals and other control signals can also adopt the above-mentioned transmission method. The present application does not impose specific restrictions on the signal transmission method of the pixel module 150. This embodiment only takes the wireless transmission method as an example.

[0034] In addition, in order to enable the pixel module 150 dropped on the substrate 110 to be quickly installed at a preset position on the substrate 110, the present application also makes improvements to the substrate 110 and the pixel module 150. The specific improvements are as follows:

[0035] A first magnet 159 is arranged at the bottom of the pixel module 150; a plurality of retaining walls 114 are arranged on the substrate 110, and the plurality of retaining walls 114 are arranged in a criss-cross manner to divide the substrate 110 into a plurality of installation areas 160 arranged in an array. When the pixel module 150 is installed, the fixing structure 130 drives the blocking structure 120 to abut against the top surface of the retaining wall 114; a mounting groove 162 is arranged in the installation area 160, and the shape of the mounting groove 162 matches the shape of the first magnet 159, and the first magnet 159 is embedded in the mounting groove 162; a second magnet 163 is arranged at a position of the mounting groove 162 corresponding to the first magnet 159, and the magnetic properties of the first magnet 159 and the second magnet 163 are opposite.

[0036] In this embodiment, a plurality of retaining walls 114 are firstly provided on the substrate 110, and the retaining walls 114 are used to divide the surface of the substrate 110 into a plurality of mounting areas 160, and a mounting groove 162 is dug in each mounting area 160, and a second magnet 163 is provided in the mounting groove 162, and a first magnet 159 is provided at the bottom of the pixel module 150; when the plurality of pixel modules 150 fall from top to bottom onto the substrate 110, some of the pixel modules 150 will first fall into the mounting area 160 surrounded by the retaining walls 114, and under the mutual attraction between the first magnet 159 of the pixel module 150 and the second magnet 163 of the mounting area 160, the pixel module 150 will actively embed into the mounting groove 162. 2, and form a stable magnetic fixation with the substrate 110; the other part of the pixel modules 150 that have not been successfully installed due to the deviation of the falling position will not generate magnetic attraction or generate strong magnetic attraction with the substrate 110, and can be poured out from the substrate 110, and then poured back onto the substrate 110 from top to bottom, and this is repeated several times until all the pixel modules 150 are embedded in the installation groove 162, and the pixel modules 150 are fixed by magnetic attraction through the first magnet 159 and the second magnet 163 in the installation groove 162; thereby completing the installation of all the pixel modules 150, effectively improving the installation efficiency of the pixel modules 150, and improving the stability of the connection between the pixel modules 150 and the substrate 110.

[0037] At the same time, in the present embodiment, wireless signal transmission is adopted between the pixel module 150 and the substrate 110, and each pixel module 150 is fixed to the substrate 110 by magnetic attraction. Therefore, when one or several pixel modules 150 fail or have display problems, they can be replaced accordingly without replacing the entire substrate 110, which effectively saves maintenance costs.

[0038] In addition, since the plurality of pixel modules 150 fall onto the substrate 110 from top to bottom, the pixel module 150 may not be facing the substrate 110 when it first falls onto the substrate 110. The light-emitting surface may face the substrate 110, or the side of the pixel module 150 may face the substrate 110. After the pixel module 150 contacts the substrate 110 and flips when it bounces, it is adjusted to the correct installation position. In order to improve the installation success rate of the pixel module 150, the present application also designs the height by which the fixing structure 130 lifts the blocking structure 120, as follows:

[0039] The predetermined height H to which the fixing structure 130 lifts the blocking structure 120 relative to the substrate 110 is greater than the length of the pixel module 150 and less than twice the length of the pixel module 150 .

[0040] When the preset height H of the blocking structure 120 is greater than twice the length of the pixel module 150, the distance between the blocking structure 120 and the substrate 110 will be larger, and the movable space of the pixel module 150 will be larger, which will easily increase the risk of the pixel module 150 falling outside the substrate 110. When the preset height H of the blocking structure 120 is less than the length of the pixel module 150, the pixel module 150 may not be able to flip normally. Therefore, in this embodiment, the preset height H of the blocking structure 120 is limited to be greater than the length of the pixel module 150 and less than twice the length of the pixel module 150. In this way, it can be ensured that the blocking structure 120 blocks the pixel module 150 from falling outside the substrate 110, while allowing the pixel module 150 to have sufficient flipping space after falling onto the substrate 110, so as to ensure that the pixel module 150 can return to the correct installation position by flipping, which is conducive to improving the success rate of the installation of the pixel module 150.

[0041] In this embodiment, the blocking structure 120 includes a cover plate 121, the area of ​​the cover plate 121 is greater than or equal to the total area of ​​the multiple installation areas 160; the cover plate 121 is provided with a through hole 122 at the position corresponding to each installation area 160, and the area of ​​the through hole 122 is greater than the area of ​​the pixel module 150.

[0042] In this embodiment, a plurality of through holes 122 are provided on the cover plate 121, so that the cover plate 121 as a whole forms a hollow cover plate 121 structure. When the plurality of pixel modules 150 fall from the top of the cover plate 121 from top to bottom, they will pass through the through holes 122 of the cover plate 121 and fall onto the substrate 110, thus not affecting the normal tipping of the plurality of pixel modules 150 on the substrate 110. At the same time, when the plurality of pixel modules 150 are in contact with the substrate 110 and then bounce up, they will be blocked by the cover plate 121. The cover plate 121 is used to restrict the plurality of pixel modules 150 between the cover plate 121 and the substrate 110, so as to prevent the pixel modules 150 from falling outside the substrate 110, thereby effectively improving the installation efficiency of the pixel modules 150.

[0043] Furthermore, a receiving groove 161 is provided between two adjacent mounting areas 160 of the substrate 110, and a portion of the fixing structure 130 is installed in the receiving groove 161; the fixing structure 130 includes a first fixing member 131 and a second fixing member 135, the first fixing member 131 and the second fixing member 135 are connected to each other, and the first fixing member 131 can move relative to the second fixing member 135 in a direction perpendicular to the substrate 110; a side of the first fixing member 131 away from the second fixing member 135 is connected to the blocking structure 120, and a side of the second fixing member 135 away from the first fixing member 131 is connected to the substrate 110; the fixing structure 130 also includes a telescopic assembly 141, and the telescopic assembly 141 includes a first telescopic rod 142, a second telescopic rod 143 and a third telescopic rod 144, and one end of the first telescopic rod 142 is connected to the second telescopic rod 14 3 is rotatably connected, and the connecting end of the first telescopic rod 142 and the second telescopic rod 143 is connected to the side wall of the accommodating groove 161; the other end of the first telescopic rod 142 is connected to the first fixing member 131, and the other end of the second telescopic rod 143 is connected to the second fixing member 135; and there is a preset angle between the first telescopic rod 142 and the second telescopic rod 143, and the third telescopic rod 144 is connected between the first telescopic rod 142 and the second telescopic rod 143; the third telescopic rod 144 is an internal hollow structure, and an air pump 170 is provided on the side of the substrate 110 away from the fixing structure 130, and an air flow channel 111 is provided inside the substrate 110, one end of the air flow channel 111 is connected to the air pump 170, and the other end is connected to the inside of the third telescopic rod 144 through the first air pipe 112, and a pressure relief valve 113 is provided on the third telescopic rod 144.

[0044] The fixed structure 130 in the present application includes three parts: a first fixing member 131, a second fixing member 135 and a telescopic assembly 141. The telescopic assembly 141 controls the movement of the first fixing member 131 relative to the second fixing member 135, so that the first fixing member 131 can drive the blocking structure 120 to rise or fall. Specifically, the present application arranges an air pump 170 on the outside of the substrate 110, and an air flow channel 111 is opened on the substrate 110. The first air pipe 112 is used to connect one end of the air flow channel 111 with the third telescopic rod 144 of the telescopic assembly 141, wherein the first telescopic rod 142, the second telescopic rod 143 and the third telescopic rod 144 can all be two-stage telescopic sleeve structures.

[0045] When multiple pixel modules 150 need to be installed, the air pump 170 is first turned on. The gas generated by the air pump 170 passes through the air flow channel 111 and the first air pipe 112 into the third telescopic rod 144. The third telescopic rod 144 begins to extend under the push of the air pressure. Under the push of the third telescopic rod 144, the first telescopic rod 142 drives the first fixing member 131 to move away from the second fixing member 135. The first fixing member 131 lifts the blocking structure 120 to a preset height H, so that a gap is formed between the blocking structure 120 and the substrate 110. When enough space is formed, multiple pixel modules 150 are poured from above the blocking structure 120. The multiple pixel modules 150 pass through the blocking structure 120 and fall onto the substrate 110, and are connected to the substrate 110 by magnetic fixation. The partially popped-up pixel modules 150 are blocked by the blocking structure 120 to prevent them from falling outside the substrate 110. For the pixel modules 150 that are not installed in place at one time, the substrate 110 is poured out again, and the above operation is repeated, so that all the pixel modules 150 are finally installed normally on the substrate 110.

[0046] During this process, the pressure relief valve 113 is always kept open, but the airflow discharged by the pressure relief valve 113 is significantly smaller than the airflow supplied by the air pump 170. When all pixel modules 150 are installed normally, the air pump 170 is turned off, and the air pump 170 stops supplying air to the airflow channel 111 inside the substrate 110, so that the airflow inside the third telescopic rod 144 is discharged to the external environment along with the pressure relief valve 113, so that the third telescopic rod 144 begins to contract, and during the contraction of the third telescopic rod 144, the first telescopic rod 142 and the first fixing member 131 are driven to move toward the substrate 110. The blocking structure 120 moves in the direction close to the second fixing member 135, so that the blocking structure 120 is driven by the first fixing member 131 to descend until the blocking structure 120 descends to abut against the top surface of the retaining wall 114; when the blocking structure 120 is a hollow cover plate 121, the cover plate 121 can just cover the top of the pixel module 150, press and limit the pixel module 150, and effectively press and fix the pixel module 150 for a second time on the basis of magnetic fixation, so that the pixel module 150 can be stably installed on the substrate 110, thereby improving the installation stability of the pixel module 150.

[0047] In this embodiment, the first fixing member 131 and the second fixing member 135 are both long strips, and may be tubular. One end of the first fixing member 131 is nested in the second fixing member 135, and may move along the extension direction of the second fixing member 135. That is, in this embodiment, the first fixing member 131 and the second fixing member 135 are nested with each other to form a two-stage telescopic sleeve structure. Driven by the telescopic assembly 141, the first fixing member 131 moves in the second fixing member 135 along the extension direction of the second fixing member 135, so that the first fixing member 131 drives the blocking structure 120 to move away from the substrate 110 or close to the substrate 110, and controls the distance between the blocking structure 120 and the substrate 110, thereby adjusting the space between the blocking structure 120 and the substrate 110, and facilitating the installation of multiple pixel modules 150.

Figure 6 As shown, Figure 6 The illustrated embodiment is based on Figure 2 The improvement is that a first snap-fit ​​portion 132 is provided on one side of the first fixing member 131 close to the second fixing member 135, and a second snap-fit ​​portion 136 is provided on the position of the second fixing member 135 corresponding to the first connecting portion, and the first snap-fit ​​portion 132 and the second snap-fit ​​portion 136 are snap-fitted and fixed; the first snap-fit ​​portion 132 and the second snap-fit ​​portion 136 are both made of elastic material.

[0049] The present embodiment is different from the previous embodiment in that the connection method between the first fixing member 131 and the second fixing member 135 is changed in the present embodiment, so that the first fixing member 131 and the second fixing member 135 can be relatively moved and detachable.

[0050] When multiple pixel modules 150 need to be installed on the substrate 110, the first fixing member 131 can be firstly connected by snapping with the second snapping portion 136 of the second fixing member 135 through the first snapping portion 132, and then the blocking structure 120 can be installed on the first fixing member 131 (the blocking structure 120 can be connected to the first fixing member 131 by gluing); when the air pump 170 is turned on, the first fixing member 131 moves upward relative to the second fixing member 135 under the drive of the telescopic component 141, and the first snapping portion 132 is connected to the second fixing member 135. The first fixing member 131 elastically stretches between the first fixing member 132 and the second snapping member 136 to release the movement, thereby ensuring that the first fixing member 131 can drive the blocking structure 120 to reach the preset height H; and when the air pump 170 is turned off, driven by the telescopic component 141, the first fixing member 131 moves downward relative to the second fixing member 135, and the first snapping member 132 and the second snapping member 136 elastically contract, so that the first fixing member 131 can drive the blocking structure 120 to abut against the retaining wall 114 and cover the pixel module 150.

[0051] When the first fixing member 131 or the blocking structure 120 is damaged or needs to be replaced, the first fixing member 131 can be directly removed from the second fixing member 135, which is convenient for disassembly, assembly and replacement; and, if there is a requirement for the overall thickness of the display panel 100 and the display panel 100 needs to be designed to be as thin as possible, the first fixing member 131 and the blocking structure 120 can be directly removed from the second fixing member 135 after the pixel module 150 is installed. This can not only appropriately reduce the overall weight of the display panel 100, but also appropriately reduce the thickness of the display panel 100.

[0052] Specifically, the second buckle portion 136 includes a first extension portion 137 and a second extension portion 139, a first protrusion 138 is provided on a side of the first extension portion 137 close to the first buckle portion 132, and a second protrusion 140 is provided on a side of the second extension portion 139 close to the second buckle portion 136, and the fixing structure 130 also includes a first elastic member 145 and a second elastic member 146, wherein the first elastic member 145 is connected between the first extension portion 137 and the second fixing member 135; wherein the first elastic member 145 and the second elastic member 146 can both be springs; and the second elastic member 146 is connected to the second extension portion 137 and the second fixing member 135. 9 and the second fixing member 135, and there is a preset angle between the first elastic member 145 and the second elastic member 146, the first elastic member 145 and the second elastic member 146 elastically support the first extension portion 137 and the second extension portion 139; the first buckle portion 132 cooperates with the shape surrounded by the first extension portion 137 and the second extension portion 139, and the first buckle portion 132 is respectively provided with a first groove 133 and a second groove 134 at the positions corresponding to the first protrusion 138 and the second protrusion 140, the first protrusion 138 is embedded in the first groove 133, and the second protrusion 140 is embedded in the second groove 134.

[0053] When the first fixing member 131 and the second fixing member 135 are installed, the first snap-fit ​​portion 132 of the first fixing member 131 and the second snap-fit ​​portion 136 of the second fixing member 135 are engaged with each other by means of protrusions and slots, and the first elastic member 145 and the second elastic member 146 can respectively provide elastic squeezing force to the first extension portion 137 and the second extension portion 139 from both sides, so that the first protrusion 138 of the first extension portion 137 can be stably embedded in the first slot 133; the second protrusion 140 of the second extension portion 139 can be stably embedded in the second slot 134, so that even if the first fixing member 131 moves relative to the second fixing member 135, it is not easy for them to fall off from each other, which further enhances the stability of the connection between the first fixing member 131 and the second fixing member 135.

[0054] Figure 7 is a schematic diagram of an embodiment of a display device of the present application, such as Figure 7 As shown, the embodiment of the present application further discloses a display device 10, including a housing 200, the display device 10 also includes the above-mentioned display panel 100, and the housing 200 wraps the display panel 100. The housing 200 is used to protect the display panel 100 from being easily damaged by external impact, and can also effectively improve the problem of corrosion inside the display panel 100 caused by external water vapor intrusion.

[0055] The display device 10 of the present application is mainly for a display device 10 having an OLED (Organic Light-Emitting Diode) display panel 100, which can be a mobile phone, a computer, a television, and other devices. The present application does not impose specific restrictions on the type of the display device 10; and in the present application, the display panel 100 in the display device 10 is mainly composed of a plurality of pixel modules 150 that can emit light independently.

[0056] In the OLED display panel 100 composed of a plurality of pixel modules 150, in order to facilitate the installation of the pixel modules 150, when assembling the plurality of pixel modules 150, the plurality of pixel modules 150 are often poured onto the substrate 110 for installation. During this process, the pixel modules 150 are prone to fall outside the substrate 110, which can easily affect the installation efficiency of the pixel modules 150.

[0057] Based on the above problems, the present application improves the display panel 100 in the display device 10. The present application sets a blocking structure 120 and a fixing structure 130 on the substrate 110 of the display panel 100. When a plurality of pixel modules 150 need to be installed on the substrate 110, the blocking structure 120 is firstly raised relative to the substrate 110 by the fixing structure 130 to a preset height H. The preset height H of the blocking structure 120 raised by the fixing structure 130 controls the size of the space between the blocking structure 120 and the substrate 110 for assembling the pixel modules 150. Then, the plurality of pixel modules 150 are installed downward from the top of the blocking structure 120. When tilted, multiple pixel modules 150 will pass through the blocking structure 120 and fall onto the substrate 110. Since some pixel modules 150 bounce back after falling onto the substrate 110, the blocking structure 120 will block the bounced pixel modules 150, so that the pixel modules 150 can only move in the space formed between the blocking structure 120 and the substrate 110, and finally the pixel modules 150 return to the substrate 110 and fall into the installation area 160 for installation, which effectively prevents the pixel modules 150 from falling outside the substrate 110 during the installation process, thereby improving the installation efficiency of the pixel modules 150 and further improving the quality of the display device 10.
