Detailed Description of the Embodiments
[0028] To enable those skilled in the art to better understand the solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure are clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. The described embodiments are merely some, rather than all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
[0029] In an embodiment of the present disclosure, FIG. 1 is a structural sectional view of a snap-fit plasma display module according to the present disclosure. As shown in FIG. 1 , the snap-fit plasma display module according to the present disclosure includes first substrate 110 and second substrate 210 arranged opposite thereto. A plasma display cavity is formed between the first substrate 110 and the second substrate 210, and the plasma display cavity is filled with plasma particles. The plasma particles include white particle 310 and black particle 320. As shown in FIG. 1 , dark particles are plasma black particles, and light particles are plasma white particles. It should be understood that the plasma particles 320 may further include two-color, three-color or multi-color pigment particles, which may be selected as required, and are not limited herein.
[0030] Glass substrates may be used as the first substrate and the second substrate, and a thin film transistor (TFT) glass substrate may be used as the second substrate.
[0031] The first substrate 110 is provided with filter layer 120, and the filter layer 120 may be arranged on a surface of the first substrate 110 facing the second substrate 210, or may be arranged on a surface of the first substrate 110 facing away from the second substrate 210, and a surface of the second substrate 210 facing the first substrate 110 is provided with pixel electrode layer 220.
[0032] Plasma isolation structure 230 extending toward the first substrate 110 is arranged on the pixel electrode layer 220, and a surface of the filter layer 120 facing the second substrate 210 is provided with snap-fit structure 160. A shape of the snap-fit structure 160 is adapted to a shape of the plasma isolation structure 230 to fix the first substrate 110 and the second substrate 210. The snap-fit structure 160 may be arranged as follows: An end of the snap-fit structure 160 facing the second substrate 210 is provided with clamping groove 161, an end of the plasma isolation structure 230 facing the first substrate 110 is embedded in the clamping groove 161, and each of the surface of the filter layer 120 facing the second substrate 210 and a surface of the snap-fit structure 160 facing the second substrate 210 is provided with conductive dielectric layer 140. The snap-fit structure includes an organic film, and the conductive dielectric layer may be made of an ITO.
[0033] The snap-fit structure 160 according to the present disclosure is provided with the clamping groove 161. In a direction shown in FIG. 1 , a top of the plasma isolation structure is embedded in the clamping groove and is attached to the snap-fit structure. The snap-fit structure is attached to the plasma isolation structure, which can increase an overall structural strength of the display, reduce movement of plasma, and reduce deformation of an upper cover plate and a lower cover plate caused by an external force, thereby improving overall pressure resistance.
[0034] In an embodiment of the present disclosure, the filter layer 120 includes a plurality of color filters 141 spaced apart, where the color filters 141 include, but are not limited to, (red green blue) RGB three-color filters, and multiple colors are displayed by the color filters. The snap-fit structure connects two adjacent color filters 141, which can reduce an influence on a display effect.
[0035] It should be noted that filling medium 130 may be arranged between every two adjacent color filters 141. When the filter layer is arranged on the surface of the first substrate facing the second substrate, the snap-fit structure 160 is arranged on a surface of the filling medium 130, or when the filter layer is arranged on the surface of the first substrate facing away from the second substrate, the snap-fit structure is directly arranged on the surface of the first substrate facing the second substrate. The filling medium 130 is preferably made of a transparent resin. Since the plasma isolation structure 230 surrounds a single pixel by one round, a gap between two adjacent color filters 141 can be filled with the filling medium, such that the filter layer is flat, and the snap-fit structure can be better arranged. The arrangement of the filling medium is a preferred solution.
[0036] It should be noted that the snap-fit structure 160 further includes supporting legs, and the supporting legs are arranged on two sides of the clamping groove. The snap-fit structure connects adjacent color filters 141 by means of the supporting legs. One or even more snap-fit structures 160 may be arranged between every two adjacent color filters 141, or snap-fit structures may be arranged only at key positions. Therefore, the specific number and positions of snap-fit structures 160 are not limited herein. For details, reference may be made to FIGS. 2 to 5 . In addition, it should be understood that the snap-fit structure is not limited to shape styles in FIGS. 2 to 5 , but may be designed and mounted with reference to shape styles in FIGS. 6 to 9 , provided that a positional relationship and a connection relationship between the snap-fit structure and the plasma isolation structure are satisfied.
[0037] In an embodiment of the present disclosure, supporting structure 330 is arranged in a plasma-filled region. Specifically, the supporting structure 330 includes a supporting microsphere, and the supporting microsphere is tangent to the conductive dielectric layer 140 and the pixel electrode layer 220, respectively. The supporting microsphere mainly achieves a supporting and fixing effect to improve pressure resistance of the display, such that an image will not be blurred or deformed when the display is pressed during display, thereby improving stability of the displayed image.
[0038] In an embodiment of the present disclosure, the pixel electrode layer 220 includes a plurality of pixel electrodes distributed in an array, a gap is formed between two adjacent pixel electrodes, and the plasma isolation structure 230 covers the gap. The plasma isolation structure 230 has a trapezoidal structure extending from the pixel electrode layer 220 to the filter layer 120, has a trapezoidal cross-sectional shape, and mainly functions to isolate plasma particles.
[0039] Another technical solution of the present disclosure provides a plasma display, including the snap-fit plasma display module according to any of the implementations described above. In a specific implementation of a display device, the display device may be specifically an electronic paper display with microcapsules or microcups, a bistable reflective liquid crystal display, or a liquid crystal display (LCD). For effects of the display device, reference may be specifically made to the effects of the plasma display module described above, which is not described herein.
[0040] A process of manufacturing the plasma display module according to the present disclosure specifically includes: first plating a color filter layer on an upper glass substrate to form color blocks with different colors, evaporating a transparent resin layer in a gap between the color filter color blocks to make a surface of the upper substrate flat, and then arranging a plasma isolation structure on a lower substrate assembly; then locating positions of a snap-fit structure and the plasma isolation structure by means of a Mark point positioning technology to ensure that a top of the plasma isolation structure can be embedded in a clamping groove of the snap-fit structure, and then attaching and mounting the snap-fit structure to an upper surface of a plasma barrier weir.
[0041] Finally, it should be noted that the above specific implementations are only intended to explain, rather than to limit the technical solutions of the present disclosure. Although the present disclosure is described in detail with reference to the examples, those of ordinary skill in the art should understand that modifications or equivalent substitutions may be made to the technical solutions of the present disclosure without departing from the spirit and scope of the technical solutions of the present disclosure, and such modifications or equivalent substitutions should fall within the scope of the claims of the present disclosure.
