[0044] Overview

[0045] As described in the background art, see Figure 1 In the aging process of the display screen (also called display panel) 2, the existing aging equipment has defects, which causes the display screen 2 to be warped near the binding area 21. When the display screen 2 is aged, the display screen 2 is first placed on the receiving platform 3, and then the IC (binding area 21) of the display screen 2 is pressed downward by the pressing head 1. The display screen 2 is effectively aligned with the FPC and pressed. When the host is powered on, the screen can be aged; however, if Figure 1 As shown, after the pressure head 1 applies pressure to the binding area 21 of the display screen 2, the display screen 2 near the binding area 21 is warped, and the warped position cannot fully fit and contact the receiving platform 3 below it. When the display screen 2 is aged, a large amount of heat will be generated. The position where the display screen 2 is in full contact with the receiving platform 3 can dissipate the heat, but the warped position of the display screen 2 is not in full contact with the receiving platform 3, causing the display screen to warp and unable to dissipate heat quickly, resulting in heat accumulation at the warped position of the display screen 2. After a long time, the display screen 2 will burn out, thereby affecting the yield rate of the display screen.

[0046] In view of the above problems, the inventors have improved the aging equipment and the structure of the pressure head of the aging equipment. A pressure block is installed on the pressure head. During aging, when the pressure head presses the binding area of ​​the display screen, the pressure block also presses the part of the display screen that is prone to warping near the binding area. This makes the entire display screen flat, allows the surface of the display screen to fit completely with the supporting platform, ensures the heat dissipation effect of the display screen during the aging process, avoids burns to the display screen 2, and improves its yield rate.

[0047] Based on the above concept, the present application will be exemplarily described below in conjunction with the accompanying drawings.

[0048] Exemplary Burn-in Equipment

[0049] This embodiment provides a display screen 2 aging device, such as Figure 2 As shown, the aging equipment includes a receiving platform 3, a pressure head 1 and a pressure block 4 connected to the pressure head 1. The display screen 2 is placed at a preset position on the receiving platform 3, and the first surface 2a of the display screen 2 close to the supporting platform 3 is in contact with the surface 3a of the receiving platform 3.

[0050] The pressing head 1 includes a second surface 2 b close to the display screen 2 and away from the carrying platform 3 . The second surface 2 b includes a first area 21 and a second area 22 . The first area 21 is close to the second area 22 and connected to the second area 22 .

[0051] The pressure head 1 is moved (e.g., can be translated up and down) by a driving member (not shown), and the pressure head 1 moves downward to press the first area 21 of the second surface 2b of the display screen 2 away from the carrying platform 3 (the first area 21 is provided with a binding area 21, and the binding area 21 is provided with a connecting terminal / pad, through which an electrical signal can be applied to the display screen 2 after connection for aging test). During aging, the number of display screens 2 that can be accommodated by the carrying platform 3 can be one or more (when multiple display screens 2 are provided, a matching number of pressure heads 1 is required).

[0052] The movement of the pressing head 1 drives the pressing block 4 to move synchronously, and the pressing block 4 presses the second area 22 of the second surface of the display screen 2 away from the supporting platform (the second area 22 is close to the first area / binding area 21 and is connected to the first area / binding area 21). There may be a position adjustment device between the pressing block 4 and the pressing head 1, and the position adjustment device can adjust the upward and downward or left and right movement of the pressing block 4 relative to the pressing head 1, and then adjust the specific position of the pressing block 4 pressing the display screen 2 according to actual needs, or adjust the distance between the pressing block 4 and the receiving platform 3 according to the thickness of the display screen 2, so as to better make the entire display screen in a flat state.

[0053] During aging, the pressing block 4 and the pressing head 1 can be pressed simultaneously to ensure that the first surface 2a of the display screen 2 is completely attached to the surface 3a of the receiving platform 3. In this way, by setting the pressing block 4, when the pressing head 1 is pressed to the first area 21, the pressing block 4 presses the second area adjacent to the first area, which is the part of the display screen 2 that is prone to warping during aging, so that the first surface of the display screen is attached to the receiving platform, and the heat generated by the display screen 2 during aging can be fully dissipated, thereby avoiding burns caused by aging of the display screen 2 and improving the yield rate.

[0054] In some embodiments, Figure 3 As shown, the pressing block 4 includes a crimping portion 41. When aging, the crimping portion contacts the second surface of the display screen. The crimping portion 41 includes a soft body, which is a soft and elastic material (such as rubber, foam / foam). In this way, when pressing, it contacts the second surface of the display screen, which can not only ensure the pressing effect but also effectively prevent the display screen from being crushed. The soft body can be foam / foam, and the crimping portion 41 is designed to be a whole piece of foam / foam structure, and the foam is fixedly bonded to the pressure head 1 by an adhesive. The soft body is a consumable and can be replaced at any time according to the size of different display screens. In other embodiments, the adhesive can be glue or double-sided tape, which is not limited here, as long as it is achieved by fixing the crimping portion 41 on the pressure head 1 (the crimping portion 41 is fixed to the side of the pressure head 1 in the direction parallel to the plane where the receiving platform 3 is located).

[0055] In some embodiments, Figure 4 As shown, the pressing block 4 includes a crimping portion 41 and a supporting portion 42. The crimping portion 41 is fixed to the side of the supporting portion 42 close to the receiving platform 3, and the supporting portion 42 is connected to the pressing head 1. The supporting portion 42 can move up and down or left and right relative to the pressing head 1, and the supporting portion 42 drives the crimping portion 41 to move. In this way, when pressing display screens of different sizes, the pressing position of the crimping portion 41 can be adjusted, thereby achieving that the display screen aging equipment can be adjusted according to different situations. At the same time, the supporting portion 42 supports and installs the crimping portion 41. During aging, the crimping portion 41 contacts the second surface of the display screen. Therefore, a material with strong support, such as plastic or metal, is used. When the crimping part 41 is pressed, it contacts the surface of the display screen 2, so the crimping part 41 can be made of a soft material, which is a soft and elastic material (such as rubber or foam); in addition, a detachable structure, such as a slot structure, or connected by an adhesive can be used between the crimping part 41 and the support part 42, wherein the adhesive can be glue or double-sided tape. When the crimping part 41 is a soft material, the soft material can be removed from the support part 42 at any time as a consumable and replaced.

[0056] It should be noted that the pressing block 4 includes the above Figure 3 and Figure 4 structure, but not limited thereto, and also include other structures with the same or similar functions.

[0057] In some embodiments, Figure 5 As shown, the support portion 42 is fixedly connected to the pressure head 1, and the connection structure adopts a detachable snap connection. A first connecting member (clip 5 or fastener 6) is arranged on the support portion 42, and a second connecting member (clip 5 or fastener 6) is arranged on the pressure head 1. The first connecting member and the second connecting member form a snap fit, which facilitates the rapid disassembly and assembly between the entire pressure block 4 and the pressure head 1.

[0058] In some embodiments, Figure 6 As shown, the support portion 42 is fixedly connected to the pressure head 1, and the connection structure is connected by a detachable screw 7. A screw hole 7 is opened on the support portion 42, and a screw hole 7 is opened on the pressure head 1. The screw 7 is passed through the support portion 42 and the pressure head 1 in turn, and the nut 8 is used to fix the tail end of the screw 7, so that the support portion 42 and the pressure head 1 are fixedly connected, and the quick disassembly and assembly between the entire pressure block 4 and the pressure head 1 is also convenient.

[0059] It should be noted that the connection structure between the support portion 42 of the pressing block 4 and the pressing head 1 includes Figure 5 and Figure 6 The structure in, but not limited to, also includes other structures with the same or similar functions.

[0060] In some embodiments, the area of ​​the pressing surface of the pressing block 4 close to the side of the supporting platform is greater than or equal to the area of ​​the second area of ​​the display screen 2 (the area prone to warping), so that the pressing surface of the pressing block 4 covers the area of ​​the display screen 2 prone to warping. In this way, it can be ensured that the pressing block 4 fully fits the area of ​​the display screen 2 prone to warping with the supporting platform 3.

[0061] like Figure 7 As shown, the pressing surface of the pressing block 4 on the side close to the bearing platform can be equal in size to the area prone to warping, ensuring that the pressing surface of the pressing block 4 completely covers the part of the display screen 2 prone to warping;

[0062] like Figure 8 As shown, the pressing surface of the pressing block 4 on the side close to the bearing platform may also be larger than the area prone to warping, ensuring that the pressing surface of the pressing block 4 completely covers the part of the display screen 2 prone to warping.

[0063] In some embodiments, before aging (at this time, the surface / pressing surface of the pressing head 1 on the side close to the supporting platform does not contact the second surface of the display screen 2), the distance between the pressing surface of the pressing head 1 and the second surface 2b of the display screen 2 is a first distance a, and the distance between the pressing surface of the pressing block 4 and the second surface 2b of the display screen 2 is a second distance b. Preferably, the first distance a is greater than or equal to the second distance b.

[0064] like Fig. 9 As shown, the first distance a and the second distance b are equal, ensuring that the pressing head 1 presses the binding area 21 of the display screen 2 while the pressing block 4 also presses the part of the display screen 2 that is prone to warping, and the display screen 2 does not warp;

[0065] like Fig.10 As shown, the first distance a is greater than the second distance b, ensuring that the pressing block 4 has pressed the part of the display screen 2 that is prone to warping before the pressing head 1 presses the binding area 21 of the display screen 2. At the same time, since the contact part between the pressing block 4 and the display screen 2 below is made of soft and elastic material, the pressing block 4 will be compressed after pressing the display screen 2, which will not affect the pressing head 1 pressing the binding area 21 of the display screen 2.

[0066] Exemplary Aging Process

[0067] This embodiment further provides a display screen aging process, wherein the display screen aging process uses any one of the display screen 2 aging devices described above to age the display screen.

[0068] like Fig.11 FIG. 1 is a display screen aging process according to an embodiment of the present application.

[0069] The display aging process includes:

[0071] S2, placing the display screen to be aged on the receiving platform,

[0072] S3, pressing the display screen with the pressure head and pressing the display screen with the pressure block, so that the surface of the display screen close to the receiving platform is in contact with the receiving platform. During aging through this process, while the pressure head presses the first area, the pressure block simultaneously presses the part of the display screen that is prone to warping, so that the entire display screen is in a flat state, and the surface of the display screen is completely in contact with the receiving platform, ensuring the heat dissipation effect of the display screen during the aging process and avoiding burns to the display screen.
