Description

Technical Field

[0001] The present invention relates to the technical field of electronic display, and specifically relates to a plasma display module with a fitting type structure and a plasma display.

Background Art

[0002] The structure of a conventional plasma display mainly consists of a glass substrate, an optical filter, an ITO layer and plasma barrier ribs in order from top to bottom. A gap exists between the plasma barrier ribs and the ITO layer, forming a plasma flow channel, but the upper and lower cover plates are easily deformed by external force, resulting in low pressure resistance of the display. Therefore, increasing the strength of the overall structure of the display, reducing the deformation of the upper and lower cover plates, and improving the overall pressure resistance of the display is a problem for those skilled in the art.

[0003] In addition, in the conventional manufacturing process, when the upper and lower glasses are combined into a box shape, there is no support at the edge of the plasma display structure, so it is usual to add support spheres to the edge sealing material to ensure that the edge does not cave in. However, since the accuracy of the support spheres cannot be guaranteed, when sealing and applying pressure, the edge caves in, the pressure applied to the whole is uneven, and ultimately problems occur such as the display medium becoming uneven, and the display at the edge not matching the display in the middle.

Summary of Invention

[0004] The present invention provides a plasma display module having a fitting type structure and a plasma display, which can solve at least one of the technical problems mentioned in the background art.

[0005] The technical solution of the present invention is as follows. The plasma display module having a fitting type structure comprises a first substrate and a second substrate disposed opposite to the first substrate. A leveling layer is disposed on the surface of the first substrate facing the second substrate, and the first groove and the second groove are etched into the leveling layer. A conductive medium layer is disposed on the first groove, the second groove, and the surface of the leveling layer facing the second substrate. A pixel electrode region is arranged on the surface of the second substrate facing the first substrate. A first support structure is arranged on the second substrate, extending in a direction toward the first substrate. One end of the first support structure, away from the second substrate, is fitted into the first groove. A second support structure is arranged on the second substrate, extending in a direction toward the first substrate. One end of the second support structure, away from the second substrate, is fitted into the second groove. The pixel electrode region is surrounded by the second support structure.

[0006] Furthermore, a light filtering layer is disposed on the surface of the first substrate facing the second substrate, the surface of the light filtering layer facing the second substrate is covered by the leveling layer, and the light filtering layer may include a plurality of color filters arranged at intervals.

[0007] Furthermore, the depth of the first groove may be the same as the thickness of the leveling layer.

[0008] Furthermore, the depth of the first groove may be equal to the sum of the thickness of the leveling layer and the thickness of the light filtering layer.

[0009] Furthermore, the width of the bottom portion of the cross-section of the first support structure and the second support structure may be greater than or equal to the width of the top portion.

[0010] Furthermore, the second support structure includes an enclosure wall or a plurality of support base bodies, and the plurality of support base bodies may be arranged at intervals.

[0011] Furthermore, if the second support structure is an enclosure wall, the second support structure may be provided with pores.

[0012] Furthermore, an adhesive medium may be filled between the first groove and the first support structure, and an adhesive medium may be filled between the second groove and the second support structure, and the adhesive medium may be used to cover the tops of the first support structure and the second support structure, and in a cured state the first substrate and the second substrate may be made into a single unit.

[0013] Furthermore, a plasma display chamber may be formed between the first substrate and the second substrate, and the plasma display chamber may be filled with plasma particles.

[0014] Another technical solution of the present invention is a plasma display having a recessed structure, which includes any one of the plasma display modules having the recessed structure described above.

[0015] The beneficial effects of the present invention are as follows. By providing a first groove and fitting the upper end of the first support structure into the first groove, the upper and lower substrates are locked together, increasing the overall strength of the display structure and perfectly solving problems in pressure resistance and environmental testing. At the same time, by arranging the second support structure at the edge of the module, the problem of lack of support at the edge of the module can be effectively solved, and the consistency between the display at the edge and the display in the middle can be improved. By distributing the second support structure in an area other than the display area and fitting its upper end into the first groove, the range of the frame-shaped adhesive is limited, preventing uneven extrusion of the display slurry and adhesive, preventing indentation of the edges of the module and display, and improving flatness.

[0017] To allow those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. The described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0018] In one technical solution of the present invention, Fig. 1 is a schematic diagram of a cross-sectional structure according to one embodiment of a plasma display module having a fitted structure of the present invention. This embodiment is a monochrome module. For color display, it is necessary to add a filter layer. Embodiments related to color will be described later.

[0019] As shown in Fig. 1, the present invention specifically comprises a first substrate 110 and a second substrate 210 disposed opposite to the first substrate. A glass substrate may be used for the first substrate and the second substrate. A TFT (Thin Film Transistor) glass substrate may be used for the second substrate.

[0020] A leveling layer (150) is arranged on a surface of a first substrate (110) facing a second substrate (210), and a first groove (130) and a second groove (170) are formed in the leveling layer (150) by etching. A conductive medium layer (140) is arranged on both the first groove (130) and the surface of the leveling layer (150) facing the second substrate (210). Here, ITO may be used as the material of the conductive medium layer.

[0021] A pixel electrode region (240) is arranged on a surface of the second substrate (210) facing the first substrate (110). The pixel electrode region (240) comprises a plurality of pixel electrodes arranged in an array.

[0022] A first support structure (220) extending in a direction facing the first substrate (110) is arranged on the second substrate (210). One end of the first support structure (220) away from the second substrate (210) is fitted into the first groove (130).

[0023] A second support structure (230) extending in a direction facing the first substrate (110) is arranged on the second substrate (210). One end of the second support structure (230) away from the second substrate (210) is fitted into the second groove (170). The pixel electrode region (240) is surrounded by the second support structure (230). Specifically, the second support structure is arranged at a position other than the display region of the plasma display module.

[0024] In one embodiment of the technical solution of the present invention, as shown in Figure 2 and Figure 3, a filter layer (120) is arranged on the surface of the first substrate (110) facing the second substrate (210). A surface of the filter layer (120) facing the second substrate (210) is covered by the leveling layer (150). The filter layer (120) comprises a plurality of color filters arranged at intervals. Here, the optical filter comprises, but is not limited to, RGB three-color color filters. This embodiment is an embodiment of a color module, and the module is made into a color display module by adding the filter layer.

[0025] As shown in Figure 2, the depth of the first groove 130 is the same as the thickness of the leveling layer. A gap is provided between adjacent color filters. The gap is covered by the first groove 130. The first groove 130 may be provided at the corners of the color filter or at other locations.

[0026] As shown in Figure 3, in this embodiment, when the first groove is formed by etching, etching is carried out until the glass substrate is reached, so that the depth of the first groove 130 is equal to the sum of the thickness of the leveling layer 150 and the thickness of the light filtering layer. The first groove 130 is located between adjacent color filters and may be provided at the corners of the color filters or at other locations. The depth range of the first groove 130 is 0.01um to 10um, preferably 1 to 6um.

[0027] In one embodiment of the technical solution of the present invention, the width of the bottom of the cross-section of the first support structure 220 and the second support structure 230 is greater than or equal to the width of the top. Preferably, the cross-sections of both the first support structure 220 and the second support structure 230 may be trapezoidal. It should be noted that the cross-sections of the first support structure and the second support structure may have other shapes and are not limited thereto.

[0028] As shown in Figures 6 and 7, the first support structure 220 may be a column structure, and this column structure may be a rectangular prism, a cylindrical shape, or other irregular three-dimensional structure. If the first support structure is a rectangular prism, its top is square. If the first support structure 220 is a cylindrical shape, its top is circular. It should be noted that the first support structure may be any other irregular shape and is not limited thereto.

[0029] It should be noted that, as shown in Figures 4 and 5, the shape of the first groove conforms to the shape of the top of the first support structure 220, and specifically, it is a square, circular, or other irregular shape.

[0030] The upper and lower substrates are supported by the first support structure 220 being fitted into the first groove 130 of the light filtering layer. This allows the upper and lower substrates to be locked together as a single unit, increasing the strength of the overall display structure, reducing deformation of the upper and lower cover plates due to external forces, and improving overall pressure resistance. In the actual manufacturing process, the first support structure 220 may be molded onto the first substrate 110 first and then connected to the second substrate 210, or it may be molded onto the second substrate 210 first and then connected to the first substrate 110, and is not limited thereto.

[0031] The density range of the first support structure 220 is from one support structure per pixel electrode to one support structure for 10,000 pixel electrodes. Preferably, there is one support structure for up to 500 pixel electrodes. The height range of the first support structure 220 is 1 to 30 μm, preferably 5 to 25 μm.

[0032] As shown in Figure 8, the second support structure may be an enclosure wall, or it may be a structure formed by surrounding multiple support base bodies. The second support structure is provided so as to surround the entire edge of the display area or display module. A common feature of both is that the cross-section of the second support structure 230 may be trapezoidal.

[0033] If the second support structure 230 is an enclosure wall, the second support structure 230 is provided with pores 250. The pores are for releasing gas from inside the module when the first substrate and the second substrate are connected.

[0034] The second support structure can be provided around the entire surface once or multiple times, so the number of second support structures is not limited. Figure 8 shows a configuration with two second support structures. The second support structure solves a problem in conventional manufacturing processes where, when the upper and lower glass pieces are joined to form a box, there is no support at the edges, causing the edges to collapse and the pressure applied to the entire surface to become uneven. By arranging the second support structure, the display medium becomes uniform, and the display at the edges and the display in the middle can be made to match.

[0035] It should be noted that the first and second support structures may be arranged irregularly, and correspondingly, their cross-sectional shapes may also be diverse. As long as the above-mentioned combination characteristics are satisfied, it is clear that other arrangement methods and cross-sectional shapes are within the scope of protection of the present invention.

[0036] In one embodiment of the technical solution of the present invention, as shown in Figures 2, 3, and 9, an adhesive medium 160 is filled between the first groove 130 and the first support structure 220. The adhesive medium 160 is also filled between the second groove 170 and the second support structure. The adhesive medium 160 is used to cover the tops of the first support structure 220 and the second support structure 230, and in the cured state, it integrates the first substrate 110 and the second substrate 210. Here, the adhesive medium 160 may be a thermosetting adhesive, a photocuring adhesive, a heat-sensitive adhesive, etc., and is preferably a highly light-transmitting curing adhesive. The adhesive medium covers the first support structure and the second support structure, and after curing and fixing, it integrates the first substrate and the second substrate, reducing the effects of heat and cold on the plasma display module. This perfectly solves the problems in environmental tests such as the module's resistance to pressure and thermal shock. When arranging the adhesive medium, the positions where the medium is filled may correspond to each support structure, or they may correspond selectively.

[0037] In one embodiment of the present invention, a plasma display chamber is formed between a first substrate 110 and a second substrate 210, and the inside of the plasma display chamber is filled with plasma particles. The plasma particles include white particles and black particles. The plasma particles may further include two-color, three-color, or multi-color pigment particles. This is not limited here, as it can be selected according to the needs.

[0038] Another technical solution of the present invention provides a plasma display having a recessed structure, which includes a plasma display module having any one of the recessed structures described above. Specific embodiments of the display device may include, specifically, a microcapsule or microcup electronic paper display, a bistable reflective liquid crystal display, and an LCD liquid crystal display. Regarding the effects of the display device, specific examples can be found by referring to the effects of the display plasma module described above, which are omitted here.
