Abstract
Description
Technical Field
[0001] The utility model relates to the field of display modules, and in particular to an anti-static display module. Background Art
[0002] OLED, Chinese name for organic light-emitting display, refers to the phenomenon that organic semiconductor materials and luminescent materials emit light through carrier injection and recombination under the drive of electric field. Its principle is to use ITO transparent electrode and metal electrode as the anode and cathode of the device respectively. Under a certain voltage drive, electrons and holes are injected from the cathode and anode into the electron and hole transport layers respectively. Electrons and holes migrate to the luminescent layer through the electron and hole transport layers respectively, and meet in the luminescent layer to form excitons and excite the luminescent molecules, which emit visible light after radiation relaxation.
[0003] For example, the patent document with application number CN201720273399.X discloses an anti-static liquid crystal display module, which uses a conductive shading tape, and sets exposed copper and a grounding solder joint electrically connected to the exposed copper on the backlight FPC, and then the grounding solder joint on the backlight FPC is electrically connected to the ground on the main FPC. Not only can the static electricity at the backlight FPC be derived from the ground on the main FPC, but the static electricity at the lower polarizer can also be derived from the ground of the main FPC through the conductive shading tape and the exposed copper on the backlight FPC, thereby realizing the deduction of static electricity at the backlight FPC and the lower polarizer.
[0004] However, the technical solution disclosed in the above patent document still has limitations in its specific implementation, because static electricity can easily enter from the edge of the glass (i.e., the display) and accumulate on the display. As excessive static electricity accumulates, once it contacts the driver IC (the location of the driver IC can be referred to in the figure), the static electricity will accumulate on the display. Figure 1 ) is prone to discharge, which can damage the driver IC and cause the module to display abnormally or even be scrapped. Utility Model Content
[0005] Based on this, it is necessary to provide an anti-static display module to address the technical problem raised in the above background technology that static electricity can easily enter from the edge of the glass and accumulate on the display. As excessive static electricity accumulates, it can easily discharge once it contacts the driver IC, thereby impacting and damaging the driver IC.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] An anti-static display module, comprising:
[0008] A substrate having a main body area and a protection area arranged outside the main body area;
[0009] An FPC board is connected to the driving IC arranged on the substrate, and a release area is arranged on the FPC board;
[0010] The protective member is arranged in the protective area. When static electricity enters the protective area at any position of the edge of the substrate and accumulates, the protective member guides the accumulated static electricity to the release area.
[0011] Furthermore, the FPC board comprises a flexible board, an end of the flexible board is connected to a driving IC arranged on the substrate, and the release area is arranged at an end of the flexible board away from the driving IC.
[0012] Furthermore, the width of the release area is smaller than the width of the FPC board.
[0013] Furthermore, the protection member includes a coil segment and a lead-out segment, the coil segment is arranged in the protection area and surrounds the outside of the main area in an annular structure, and the lead-out segment connects the coil segment with the release area.
[0014] Furthermore, the coil segment has an opening, and the lead-out segment has two sections which are respectively arranged at two ends of the opening.
[0015] Furthermore, the substrate surface has a limiting portion for limiting the position of the coil segment within the protection area.
[0016] Furthermore, the limiting portion is a groove arranged on the surface of the substrate, the arrangement trajectory of the groove matches the shape of the coil segment, and an expansion groove is arranged at a position corresponding to the edge of the substrate surface and the lead-out segment.
[0017] Furthermore, the groove width of the groove is not greater than the width of the lead-out section.
[0018] Furthermore, the limiting portion is a plurality of fittings arranged on the surface of the substrate, the surface of the fittings has a locking groove, and the plurality of fittings are arranged along the outer contour of the coil segment.
[0019] Furthermore, the inner side wall of the slot of the locking slot has a limiting protrusion.
[0020] Compared with the prior art, the utility model has the following beneficial effects:
[0021] The utility model can lead out static electricity that enters and accumulates at any position of the edge of the substrate through the protective member, thereby reducing the probability of static electricity that enters and accumulates from the edge of the glass and damages the driver IC. Specifically, when static electricity enters the protective area at any position of the edge of the substrate and accumulates, the protective member leads the accumulated static electricity to the release area for discharge.
[0022] Under normal circumstances, when the protective parts are not set, static electricity enters from the edge of the glass. Excessive static electricity accumulation will impact and damage the driver IC, causing abnormal display of the module or even scrapping. After the protective parts are set, static electricity enters from the edge of the glass and is conducted away by the ITO metal wire (i.e. the protective parts) and released to the remote common copper pad (i.e. the release area) through the FPC, thereby avoiding static electricity damage to the driver IC and greatly improving the anti-static ability of OLED.
[0023] Although the setting of the coil segment can guide the static electricity out of the body immediately, the coil segment is prone to positional displacement during installation or use. Therefore, the position of the coil segment in the protection zone is restricted by the groove, and the expansion groove can restrict the out-of-body segment at the same time. Under such an effect, the coil segment and the out-of-body segment will no longer easily be displaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0033] As mentioned in the background technology, static electricity easily enters from the edge of the glass (i.e., the display) and accumulates on the display. As excessive static electricity accumulates, once it comes into contact with the driver IC (the location of the driver IC can be referred to Figure 1 ) is prone to discharge, which can damage the driver IC and cause the module to display abnormally or even become scrapped.
[0034] In order to solve this technical problem, the utility model provides an anti-static display module.
[0035] Specifically, please refer to Figures 1 to 6 , anti-static display module, including:
[0036] A substrate 1 having a main area 4 and a protection area 3 arranged outside the main area 4;
[0037] An FPC board 2 is connected to a driving IC arranged on the substrate 1, and a release area 6 is arranged on the FPC board 2;
[0038] The protective member 5 is arranged in the protective area 3 . When static electricity enters the protective area 3 at any position of the edge of the substrate 1 and accumulates, the protective member 5 conducts the accumulated static electricity to the release area 6 .
[0039] The utility model can lead out static electricity that enters and accumulates at any position of the edge of the substrate 1 through the protective member 5, thereby reducing the probability of static electricity that enters and accumulates from the edge of the glass and damages the driver IC. Specifically, when static electricity enters the protective area 3 at any position of the edge of the substrate 1 and accumulates, the protective member 5 leads the accumulated static electricity to the release area 6 for discharge.
[0040] Combination Figure 1For example, under normal circumstances, when the protective member 5 is not set, static electricity enters from the edge of the glass, and excessive static electricity accumulation will impact and damage the driver IC, causing abnormal display of the module or even scrapping. After the protective member 5 is set, the static electricity enters from the edge of the glass and is conducted away by the ITO metal wire (i.e., the protective member 5, ITO stands for indium tin oxide, which is a transparent conductive material widely used in electronic devices. Due to its unique properties, such as high transparency and good conductivity, ITO plays a key role in a variety of display technologies and touch screen applications.) and releases the charge to the remote common copper pad (i.e., release area 6) through the FPC, thereby avoiding static electricity damage to the driver IC and greatly improving the anti-static ability of the OLED.
[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0044] Please refer to Figure 1 to Figure 2 , anti-static display module, including:
[0045] A substrate 1 having a main area 4 and a protection area 3 arranged outside the main area 4;
[0046] An FPC board 2 is connected to a driving IC arranged on the substrate 1, and a release area 6 is arranged on the FPC board 2;
[0047] The protective member 5 is arranged in the protective area 3. When static electricity enters the protective area 3 at any position of the edge of the substrate 1 and accumulates, the protective member 5 will lead the accumulated static electricity to the release area 6. The utility model can lead the static electricity that enters and accumulates at any position of the edge of the substrate 1 through the protective member 5, thereby reducing the probability of static electricity entering and accumulating from the edge of the glass to damage the driver IC. Specifically, when static electricity enters the protective area 3 at any position of the edge of the substrate 1 and accumulates, the protective member 5 will lead the accumulated static electricity to the release area 6 for discharge.
[0048] To minimize the probability of electrostatic damage to the driving IC, the width and specific position of the release area 6 are further defined. The FPC board 2 includes a flexible board, and the end of the flexible board is connected to the driving IC disposed on the substrate 1. The release area 6 is provided at one end of the flexible board away from the driving IC. Such a setting can make the release area 6 far away from the driving IC to a large extent, avoiding the phenomenon that the driving IC is damaged by impact. (In a display module, the driving IC (Integrated Circuit) is a key component. Its main function is to control and drive the pixels on a display panel such as a liquid crystal display (LCD) or an organic light-emitting diode (OLED). The driving IC is responsible for receiving image data and control signals from the system main control chip (such as a microprocessor or a microcontroller), and then converting them into the voltage and current required by the display panel to correctly display the image. The driving IC is usually integrated on one or more small circuit boards, and these circuit boards are connected to the display panel through a flexible printed circuit (FPC) or a connector. The design and performance of the driving IC directly affect key parameters such as the resolution, refresh rate, color performance, and power consumption of the display module. Therefore, selecting a suitable driving IC is crucial for ensuring the quality and performance of the display module).
[0049] In some specific embodiments, the width of the release area 6 is smaller than the width of the FPC board 2. Such a setting is to make the range of the release area 6 sufficient to fully release the static electricity.
[0050] Further optimizing the anti-static display module provided in Embodiment 1, in some specific embodiments, the protective member 5 includes a coil section 7 and a lead-out section 8. The coil section 7 is disposed in the protection area 3 and is in a circular structure surrounding the outside of the main body area 4. The lead-out section 8 connects the coil section 7 to the release area 6. The coil section 7 can be in Figure 2 the state shown in, or can also be in a U-shaped structure, and preferably a U-shaped structure here.
[0051] In some specific embodiments, the coil section 7 has an opening, and the lead-out section 8 has two sections and is respectively disposed at both ends of the opening.
[0052] In some specific embodiments, the surface of the substrate 1 has a limiting portion for limiting the position of the coil section 7 in the protection area 3.
[0053] Due to the setting of the coil section 7, the static electricity that enters and accumulates at the glass edge will be transferred to the coil section 7 for the first time, and then, through the coil section 7, it will be transferred to the lead-out section 8 and finally enter the release area 6.
[0054] Please refer to Figure 3 to Figure 4, the anti-static display module provided in Example 1 or 2 is further optimized, the protective member 5 includes a coil segment 7 and a lead-out segment 8, the coil segment 7 is arranged in the protective area 3 and surrounds the outside of the main area 4 in an annular structure, and the lead-out segment 8 connects the coil segment 7 with the release area 6. The coil segment 7 has an opening, and the lead-out segment 8 has two sections and is respectively arranged at both ends of the opening. The surface of the substrate 1 has a limiting portion for limiting the position of the coil segment 7 in the protective area 3, and the limiting portion is a groove 9 arranged on the surface of the substrate 1, and the setting trajectory of the groove 9 matches the shape of the coil segment 7, and an expansion groove 10 is provided at the edge of the surface of the substrate 1 corresponding to the lead-out segment 8.
[0055] In some specific embodiments, the groove width of the groove 9 is not greater than the width of the lead-out section 8 .
[0056] Although the setting of the coil segment 7 can guide the static electricity to be discharged immediately, the coil segment 7 is prone to positional displacement during installation or use. Therefore, the position of the coil segment 7 in the protection area 3 is restricted by the groove 9, and the expansion groove 10 can restrict the discharge segment 8. Under such an effect, the coil segment 7 and the discharge segment 8 will no longer easily be displaced.
[0057] Please refer to Figure 5 to Figure 6 , the anti-static display module provided in the above embodiments is further optimized, the protective member 5 includes a coil segment 7 and a lead-out segment 8, the coil segment 7 is arranged in the protective area 3 and surrounds the outside of the main area 4 in an annular structure, and the lead-out segment 8 connects the coil segment 7 with the release area 6. The coil segment 7 has an opening, and the lead-out segment 8 has two sections and is respectively arranged at both ends of the opening. The surface of the substrate 1 has a limiting portion for limiting the position of the coil segment 7 in the protective area 3, and the limiting portion is a plurality of fittings 11 arranged on the surface of the substrate 1, and the surface of the fitting 11 has a positioning groove 12, and the plurality of fittings 11 are arranged along the outer contour of the coil segment 7.
[0058] In some specific embodiments, the inner side wall of the locking groove 12 has a limiting protrusion 13 .
[0059] It is difficult to open the groove 9 , so the position of the coil segment 7 in the protection area 3 can be limited by the positioning groove 12 on the fitting 11 , and the limiting protrusion 13 can prevent the coil segment 7 from escaping from the notch of the positioning groove 12 .
[0060] The use process of the anti-static display module provided by the utility model is as follows: the utility model can lead out the static electricity that enters and accumulates at any position of the edge of the substrate through the protective member, thereby reducing the probability of static electricity that enters and accumulates from the edge of the glass and damages the driver IC. Specifically, when static electricity enters the protective area at any position of the edge of the substrate and accumulates, the protective member leads the accumulated static electricity to the release area for discharge.
