Description

[0002] Displays include televisions. After years of development, flat-panel LCD TVs have made great technological advances in many aspects such as morphological structure and cost optimization. However, there is still a lot of room for optimization in the structural form of modules.

[0003] At present, according to the backlight requirements of the LCD panel, the industry sets a source circuit board (S-PCB) at the bottom of the LCD panel. The S-PCB is in a long strip shape and is usually fixed by folding it at the bottom of the back panel to the side of the back panel facing the rear shell. This type of structure requires a Chip On Flex (COF) avoidance position at the bottom of the back panel, a folding space for the S-PCB and a fixing position for the decorative strip. These features cause great damage to the back panel, making it easy to deform and affect the backlight, thereby causing problems such as light leakage and poor lighting effect.

[0004] Among them, the decorative strip is L-shaped and connected to the back panel to protect the COF and the heat dissipation of the COF on the front and bottom; the S-PCB extends along the length direction of the back panel and extends to the side of the TV, and the back shell needs to cover the S-PCB for protection. Therefore, both ends of the back shell must extend to the sides of the TV, making the back shell in a "J" shape; the length of the S-PCB changes according to the size of the TV, that is, the size of the back shell also needs to change according to the size of the TV, which also leads to the fact that the back shells of TVs of different sizes cannot be shared, increasing the mold opening cost.

Figure 2 An exploded view of a display provided by an embodiment of the present application is shown. Figure 3 A cross-sectional view of a first display provided by an embodiment of the present application is shown, Figure 4 Show Figure 3 An enlarged schematic diagram of part A is shown.

[0038] like Figures 1 to 4 As shown, the embodiment of the present application provides a display, including a liquid crystal panel 1, a backlight module, a circuit board 4 and a chip-on-film 5. The backlight module includes a back plate 2 and a bracket 3. The back plate 2 includes a main plate 21 and a frame 22. The frame 22 is arranged on the peripheral side of the main plate 21 to form an inner cavity of the back plate 2. The main plate 21 is spaced apart from the liquid crystal panel 1. The frame 22 extends from one end of the back plate 2 to the peripheral side of the liquid crystal panel 1. The bracket 3 is located in the inner cavity of the back plate 2 and is arranged between the liquid crystal panel 1 and the main plate 21. The two ends of the bracket 3 are respectively connected to the liquid crystal panel 1 and the main plate 21. The circuit board 4 is located in the inner cavity of the back plate 2 and is detachably connected to the bracket 3. The chip-on-film 5 is located in the inner cavity of the back plate 2. One end of the chip-on-film 5 is connected to the circuit board 4 and the other end is connected to the liquid crystal panel 1.

[0039] It should be understood that the backlight module also includes a diaphragm assembly 6 and a backlight assembly 7, both of which are located in the inner cavity of the back panel 2 and are arranged between the liquid crystal panel 1 and the main panel 21. The display also includes a main board 8 and a rear shell 9. The main board 8 is arranged on the side of the main panel 21 facing away from the liquid crystal panel 1, and the rear shell 9 covers the main board 8 and is connected to the side of the main panel 21 facing away from the liquid crystal panel 1.

[0040] The back panel 2 includes a main body panel 21 and a frame 22. The main body panel 21 is in the shape of a rectangular parallelepiped. The frame 22 is arranged around the main body panel 21 and is arranged together with the main body panel 21 to form an inner cavity of the back panel 2. The main body panel 21 and the frame 22 are integrally formed, so that the display of the present application does not need to be additionally provided with a middle frame, thereby reducing the production cost of the middle frame, and also reducing the installation steps of the operator, thereby improving the convenience of installation; the main body panel 21 is located between the backlight assembly 7 and the main board 8, and the frame 22 extends from one end of the back panel 2 to the peripheral side of the liquid crystal panel 1 and is connected to the liquid crystal panel 1, so that the diaphragm assembly 6 and the backlight assembly 7 are both located in the inner cavity of the back panel 2, and the frame 22 is arranged at an angle so that the inner cavity of the back panel 2 gradually increases toward the opening end.

[0041] Reference Figure 4-Figure 6 , Figure 5 A partial cross-sectional view of a first display provided by an embodiment of the present application is shown. Figure 1 , Figure 6 A partial cross-sectional view of a first display provided by an embodiment of the present application is shown. Figure 2 .

[0042] The bracket 3 is located in the inner cavity of the back panel 2 and is arranged at the lower end of the back panel 2. The bracket 3 is located between the liquid crystal panel 1 and the main panel 21. The end of the bracket 3 facing the main panel 21 can be connected to the main panel 21 by bolts, bonding or welding. The end of the bracket 3 facing the liquid crystal panel 1 is connected to the liquid crystal panel 1 by double-sided tape and foam. The foam is a flexible material to prevent the liquid crystal panel 1 from colliding with the bracket 3 during installation, thereby protecting the liquid crystal panel 1.

[0043] The circuit board 4 is a source circuit board, referred to as S-PCB. The circuit board 4 is arranged in a long strip shape and extends along the length direction of the liquid crystal panel 1 and is slightly shorter than the length of the liquid crystal panel 1. The circuit board 4 is located in the inner cavity of the back plate 2, and the circuit board 4 is detachably connected to the bracket 3, so that the circuit board 4 is installed, that is, there is no need to set a mounting position for the circuit board 4 on the back plate 2. The chip-on-chip film 5 is also located in the inner cavity of the back plate 2, one end of the chip-on-chip film 5 is connected to the circuit board 4 and the other end is connected to the liquid crystal panel 1, that is, there is no need to set a clearance position for the chip-on-chip film 5 on the back plate 2, nor is there a need to set a decorative strip on the back plate 2 to protect the chip-on-chip film 5.

[0044] The present application can arrange the circuit board 4 and the chip-on-cover film 5 in the inner cavity of the back plate 2 by setting the bracket 3, without damaging the back plate 2, and at the same time, it is not necessary to set the folding space of the circuit board 4 on the bottom plate of the back plate 2, so as to avoid the deformation of the back plate 2 affecting the backlight and causing light leakage, poor light effect and other problems. At the same time, the circuit board 4 is no longer arranged on the back of the back plate 2, so there is no need for the back shell 9 to cover and protect the circuit board 4, so that the size of the back shell 9 does not need to be changed according to the size of the TV, that is, the back shell 9 can be universal to reduce the mold opening cost. The back shell 9 can be a square cover, and the motherboard 8, power supply and logic board (T-CON) and other components are covered to avoid the lower end of the back shell 9 extending along the length direction of the back plate 2, so that the side of the display is less thick than the back shell, making the side of the whole machine thinner. In order to further reduce the size of the back shell 9, the motherboard 8, power supply and logic board (T-CON) adopt a three-in-one board, thereby reducing the volume of the back shell 9 that needs to be covered and reducing the size of the back shell 9. At the same time, the main body plate 21 and the frame 22 of the back plate 2 are formed in one piece, so that the integrity is better and the appearance is better.

[0045] In some optional embodiments, the bracket 3 includes an inclined plate 31, a first connecting plate 32 and a second connecting plate 33. The inclined plate 31 is spaced apart from the bottom surface of the frame 22 for installing the circuit board 4 and the chip-on-cover film 5. One end of the first connecting plate 32 is connected to the inclined plate 31, and the other end is bent to form a bending portion, which is parallel to the liquid crystal panel 1, and is used to connect to the liquid crystal panel 1. One end of the second connecting plate 33 is connected to the inclined plate 31, and the second connecting plate 33 is detachably connected to the main plate 21.

[0046] The bracket 3 can be made of aluminum profiles, sheet metal, plastic and other materials. Profile sheet metal materials have better strength, but poor assembly effect and high cost; plastic strength is slightly weaker, but better assembly performance and low cost. This solution is mainly explained based on the plastic bracket.

[0047] The first connecting plate 32 and the second connecting plate 33 are respectively arranged at both ends of the inclined plate 31 along the width direction. The inclined plate 31, the first connecting plate 32 and the second connecting plate 33 are all formed in one piece. The inclined arrangement of the inclined plate 31 reduces the interval between the liquid crystal panel 1 and the main plate 21 compared to the horizontal arrangement of the inclined plate 31, thereby reducing the thickness of the display. The inclined plate 31 is arranged at an interval with the bottom surface of the frame 22 to form a mounting cavity. The circuit board 4 is located in the mounting cavity and is connected to the inclined plate 31.

[0048] The first connecting plate 32 is arranged horizontally and can be used to support the membrane assembly 6 and the backlight assembly 7. One end of the first connecting plate 32 away from the inclined plate 31 is bent to form a bent portion, which is connected to the liquid crystal panel 1. The bent portion is arranged parallel to the liquid crystal panel 1, thereby increasing the connection area between the first connecting plate 32 and the liquid crystal panel 1, and facilitating the arrangement of double-sided adhesive and foam between the first connecting plate 32 and the liquid crystal panel. The second connecting plate 33 is connected to the main plate 21, and the second connecting plate 33 is arranged parallel to the main plate 21, thereby increasing the contact area between the second connecting plate 33 and the main plate 21, and further improving the stability of the connection between the second connecting plate 33 and the main plate 21.

[0049] The second connecting plate 33 and the main plate 21 can be detachably connected, and can be connected by bonding or bolting, or by providing a positioning piece on one of the second connecting plate 33 and the main plate 21 and a positioning hole on the other, and connecting by inserting the positioning piece into the positioning hole.

The materials of the first gasket 41 and the second gasket 42 are both flexible materials, such as EVA or silicone. The circuit board 4 is located in the installation cavity of the inclined plate 31 and the frame 22. The circuit board 4 is tilted and parallel to the inclined plate 31, and the first gasket 41 and the second gasket 42 are also tilted. The lower end of the first gasket 41 is engaged with the snap-fit ​​block 34, so that the circuit board 4 is positioned, so that the circuit board 4 is fixed in the installation cavity. The first gasket 41 can also prevent the circuit board 4 from colliding with the inclined plate 31, and protect the circuit board 4. The second gasket 42 abuts against the frame 22. The setting of the second gasket 42 also prevents the circuit board 4 from colliding with the frame 22, and also protects the circuit board 4.
