Description

A backplane structure Technical Field

[0001] The utility model belongs to the technical field of display accessories, and more specifically, relates to a back plate structure. Background Art

[0002] The backplane is a circuit board or frame that supports other circuit boards, devices and the interconnection between devices, and provides power and data signals for the supported devices; the backplane is generally installed with prisms, diffusers, light guides, reflectors, etc. In order to increase the stability of the internal components of the backplane, the backplane is generally fixed or glued with a plastic frame around the rectangular backplane. However, the lower side of the display panel is a single-layer lower glass substrate. When producing LCD panels and complete machines, the lower single-layer glass substrate is prone to cracks caused by external force and then breaks, resulting in abnormal display.

[0003] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a back plate structure is provided in order to achieve the purpose of having more practical value.

[0004] Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a back panel structure to solve the problem that the ordinary back panel structure is insufficient in strength and the glass substrate around the panel is easily broken when subjected to external force, especially the problem of the single-layer lower glass substrate at the bottom of the panel breaking.

[0006] The purpose and effect of the back plate structure of the present invention are achieved by the following specific technical means:

[0007] A backboard structure includes a rectangular bottom plate, wherein the edges of the bottom plate are vertically provided with folded ends, and notches are provided at the corners between adjacent folded ends; the top of the folded end located at the bottom edge of the bottom plate extends inwardly with an inward fold, and a convex strip is also provided on the top of the folded end of the bottom edge.

[0008] Furthermore, the convex strip and the folded end are integrally formed.

[0009] Furthermore, the sum of the height of the folded end of the bottom of the bottom plate and the height of the convex strip is equal to the height of the folded ends of the other three sides of the bottom plate.

[0010] Furthermore, a pasting plate is provided on the bottom side of the bottom plate, and the inner fold, the convex strip and the pasting plate are integrally formed into a retaining wall, the retaining wall is buckled on the fold end, and the pasting plate is fixedly connected to the bottom plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The folded end, inward fold and convex strips at the bottom edge of the back panel form a retaining wall, which does not increase the bottom width of the lower side of the LCD module, thereby protecting the lower side glass of the LCD module and significantly reducing the incidence of LCD panel glass breakage.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] Example 1:

[0025] As shown in Figures 1 to 4 and 6:

[0026] The utility model provides a back plate structure, including a rectangular bottom plate 11, with folded ends 12 vertically provided on all edges of the bottom plate 11, and notches 7 are provided at the corners between adjacent folded ends 12; an inner fold 13 extending vertically inward is provided on the top of the folded end 12 on the bottom side of the bottom plate 11, so that the lower end portion of the back plate is U-shaped as a whole, and a convex strip 14 is further provided on the top of the folded end 12, and the convex strip 14 is integrally formed with the folded end 12 and the inner fold 13. As shown in Figure 4, a lower glass substrate 3 is placed in the back plate, and the lower glass substrate 3 is supported by the inner fold 13, and the bottom side of the lower glass substrate 3 is limited by the convex strip 14. The bottom of the lower glass substrate 3 is tightly against the lower polarizer 2, and the upper glass substrate 4 and the upper polarizer 5 are overlapped from the inside to the outside above the lower glass substrate 3, and a plastic frame 6 is clamped around the bottom plate 11, and the limiting corners of the plastic frame 6 are clamped at the corresponding notches 7, and the plastic frame 6 is used to reinforce the position of each module;

[0027] The heights of the protrusions on all sides of the bottom plate 11 are consistent, and the sum of the heights of the folded end 12 at the bottom of the bottom plate 11 and the convex strip 14 is equal to the heights of the folded ends 12 on the other three sides of the bottom plate 11. The folded end 12, the inner fold 13 and the convex strip 14 on the lower side of the back plate form a retaining wall, which does not increase the width of the lower side of the LCD module, thereby protecting the glass substrate on the lower side of the LCD module and significantly reducing the incidence of LCD panel glass breakage.

[0028] The ordinary lower bottom usually uses a plastic frame 6 as a convex strip 14, which is adhered to the U-shaped inner fold 13 of the back panel by tape. However, the U-fold will have a certain chamfer, and the chamfer cannot be smoothly adhered to the plastic frame convex strip 14. If you want to have a retaining wall to protect the glass substrate 3, the minimum width here is the chamfer radius plus the width of the plastic frame convex strip 14, which is much larger than the thickness of the back panel. If the edge of the glass substrate 3 and the back panel edge are too small, the plastic frame retaining wall cannot be formed, resulting in the bottom glass having no retaining wall protection and being easily damaged. In this embodiment, the foldable end and the convex strip are integrally formed, and the glass substrate is protected by a retaining wall without increasing the width from the lower glass substrate to the back panel edge.

[0029] Example 2:

[0030] As shown in Figure 5:

[0031] The difference between this embodiment and the first embodiment is that a pasting plate 15 is provided on the bottom side of the bottom plate 11, and the inner fold 13, the convex strip 14 and the pasting plate 15 are integrally formed into a retaining wall. The retaining wall is buckled on the fold end 12, and the pasting plate 15 is fixedly connected to the bottom plate 11, so that the inner fold 13 and the convex strip 14 are not directly integrally formed with the bottom plate 11, but can achieve the same retaining wall effect. This design method will cause the bottom side of the back plate to become thicker, but it is simpler to produce.

[0032] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
