Description

Technical Field

[0001] The utility model relates to the technical field of displays, and particularly to a display device. Background Art

[0002] Liquid crystal display devices have the advantages of low operating voltage, light weight, small volume, etc., and are widely used in various display devices. Figure 1 FIG. is a schematic structural diagram of a display device provided by the prior art. Figure 2 FIG. is a bottom view of a partial structure of the display device provided by the prior art. As Figure 1 and Figure 2 shown, the display device includes a backlight module 10', a circuit board 20', and a display panel 30'. The circuit board 20' is disposed on one side of the backlight module 10', and the display panel 30' is disposed on the upper side of the backlight module 10'. The backlight module 10' includes a back plate 11', a light strip assembly 13', a light guide plate 12', and an optical film 14'. Among them, the back plate 11' includes a bottom plate portion 111', a side plate portion 112', and a lamp housing portion 113'. The side plate portion 112' is perpendicularly disposed with respect to the bottom plate portion 111', and the lamp housing portion 113' is connected to the side plate portion 112' and is disposed opposite to the bottom plate portion 111'. The light guide plate 12' is disposed on the bottom plate portion 111', and the optical film 14' is disposed on the light guide plate 12'. The light strip assembly 13' includes a light strip 131' and a flexible circuit board 132'. The light strip 131' is disposed between the light guide plate 12' and the side plate portion 112', and the flexible circuit board 132' is used to connect the light strip 131' to the circuit board 20'. Specifically, a through hole 114' is formed at the intersection of the bottom plate portion 111' and the side plate portion 112'. After the flexible circuit board 132' passes through the back plate 11' from the inside to the outside through the through hole 114', it is electrically connected to the circuit board 20'.

[0003] Since the back plate has relatively high requirements for the structural strength at the connection between the side plate portion and the bottom plate portion, the setting of the through hole 114' may cause the overall structural strength of the backlight module 10' to fail to meet the usage requirements, and light leakage may also occur at the through hole 114', affecting the display quality of the display panel.

[0046] Embodiment 1

[0047] Figure 3 is a partial cross-sectional view of the display device provided in this embodiment; as Figure 3 shown, the display device includes a backlight module 10, a circuit board 20, a display panel 30, and a coating layer 50. Among them, the display panel 30 is disposed on the upper side of the backlight module 10, and the backlight module 10 is used to provide light source for the liquid crystal display panel 30, and the display panel 30 is used to realize the display of images. Optionally, the display panel 30 may be a liquid crystal display panel 30. The circuit board 20 is disposed on the side of the backlight module 10, and both the display panel 30 and the backlight module 10 are electrically connected to the circuit board 20. The coating layer 50 starts from the lower side of the backlight module 10 and extends laterally to cover the circuit board 20, and then extends upward and finally overlaps on the upper side of the display panel 30. The coating layer 50 can not only play an insulating and protective effect on the circuit board 20, but also play a light-shielding effect.

[0048] As Figure 3As shown, the backlight module 10 includes a back plate 11, a light guide plate 12, a lamp strip assembly 13, and an optical film 14. Among them, the back plate 11 includes a bottom plate portion 111, a side plate portion 112, and a lamp cover portion 113. The side plate portion 112 is erected on the bottom plate portion 111, and the lamp cover portion 113 is connected to the side plate portion 112 and is disposed opposite to the bottom plate portion 111. The light guide plate 12 is disposed on the upper side of the bottom plate portion 111 and is parallel to the bottom plate portion 111. The optical film 14 is disposed on the upper side of the light guide plate 12. The lamp strip assembly 13 includes a lamp strip 131 and a flexible circuit board 132. The lamp strip 131 is disposed between the side plate portion 112 and the light guide plate 12, and the flexible circuit board 132 is used to realize the electrical connection between the lamp strip 131 and the circuit board 20. Specifically, the first end of the flexible circuit board 132 is connected to the lamp strip 131, and the second end extends out of the back plate 11 from the upper side of the back plate 11 and is electrically connected to the circuit board 20. Thus, there is no need to provide an opening at the intersection position of the bottom plate portion 111 and the side plate portion 112, which can not only improve the structural strength of the backlight module 10, but also avoid the light leakage problem at the intersection position of the bottom plate portion 111 and the side plate portion 112, and improve the display effect of the display device.

[0049] Figure 4 is a bottom view of a partial structure of the display device provided in this embodiment, as Figure 3 and Figure 4 shown, the first end of the flexible circuit board 132 is attached to the side (i.e., the lower side) of the lamp cover portion 113 facing the bottom plate portion 111, the lamp strip 131 is disposed on the side of the first end facing the bottom plate portion 111, and the second end of the flexible circuit board 132 extends out from between the lamp cover portion 113 and the light guide plate 12 to the outside of the lamp cover portion 113 and bypasses the upper side of the lamp cover portion 113 to the outside of the back plate 11 to be electrically connected to the circuit board 20. That is, by bending the flexible circuit board 132 on both sides, the flexible circuit board 132 is led out from the upper side of the back plate 11, and there is no need to open any holes or slots on the back plate 11, ensuring the structural strength of the backlight module 10.

[0050] In this embodiment, the lamp strip assembly 13 further includes a connector 134. The connector 134 is connected to one end of the flexible circuit board 132 away from the lamp strip 131 and is electrically connected to the flexible circuit board 132. The connector 134 is inserted and matched with the circuit board 20, so as to realize the electrical connection between the lamp strip 131 and the circuit board 20. In this embodiment, after the flexible circuit board 132 extends out from the upper side of the lamp cover portion 113, it bends downward from the gap between the circuit board 20 and the back plate 11 and is attached and disposed on the lower side of the circuit board 20. The connector 134 is also connected to the lower side of the circuit board 20.

[0051] Optionally, as Figure 4As shown, the flexible circuit board 132 is configured in an L shape. Preferably, the light strip assembly 13 further includes a pulling strip 133. The pulling strip 133 is disposed on the side of the flexible circuit board 132 facing away from the circuit board 20, and one end thereof is connected to the connector 134, and the other end is for an operator to grasp. When assembling the display device, the operator grasps the pulling strip 133 to plug the connector 134 onto the circuit board 20, improving the convenience of assembly.

[0052] Optionally, the side (i.e., the upper side) of the first end of the flexible circuit board 132 facing away from the bottom plate portion 111 can be adhered to the lower side of the lamp shade portion 113 by double-sided tape. In other embodiments, the first end of the flexible circuit board 132 can also be fixed to the lower side of the lamp shade portion 113 by means of fastening, etc.

[0053] As Figure 3 shown, the end portion of the light guide plate 12 extends between the lamp shade portion 113 and the bottom plate portion 111. The portion of the flexible circuit board 132 opposite to the light guide plate 12 is adhered to the end portion of the light guide plate 12 by double-sided tape, thereby improving the overall fixing firmness of the light strip assembly 13.

[0054] As Figure 1 shown, in the prior art, in order to reduce the light loss of the lamp strip 131', a reflective sheet 15' is usually fixed to the lower side of the lamp shade portion 113'. However, the setting of the reflective sheet 15' will cause an increase in the thickness of the entire backlight module 10'. In this regard, as Figure 3 shown, in this embodiment, white paint is coated on the portion of the first end of the flexible circuit board 132 opposite to the light guide plate 12. The setting of the white paint can reflect light, reduce light damage, and will not cause an increase in the thickness of the backlight module 10.

[0055] Generally, the end portion of the display panel 30 is adhered to the side of the lamp shade portion 113 facing away from the bottom plate portion 111 by a light-shielding tape 40. In order to prevent the bent flexible circuit board 132 from causing an increase in the thickness of the display device, as Figure 3 shown, a first avoidance groove 421 is opened in the light-shielding tape 40 along its thickness direction, and the portion of the flexible circuit board 132 located on the upper side of the lamp shade portion 113 is received in the first avoidance groove 421. In this embodiment, by embedding the portion of the flexible circuit board 132 located on the upper side of the lamp shade portion 113 in the light-shielding tape 40, it is prevented that the display device has an increased thickness due to the bent flexible circuit board 132.

[0056] Figure 5 is a cross-sectional view of the first mating portion of the flexible circuit board and the lamp shade portion provided in this embodiment. As Figure 5As shown in the figure, the light-shielding tape 40 includes a first tape layer 41 and a second tape layer 42. Among them, the first tape layer 41 is attached to the upper side of the lamp cover portion 113, the second tape layer 42 is attached to the upper side of the first tape layer 41, a first avoidance groove 421 is provided on the second tape layer 42, and the part of the flexible circuit board 132 located on the upper side of the lamp cover portion 113 is accommodated in the first avoidance groove 421. The first tape layer 41 is bonded to the display panel 30. With such a setting, not only can the flexible circuit board 132 be accommodated to avoid an increase in the thickness of the display device, but also the upper surface of the light-shielding tape 40 is made flush, thus ensuring the flatness of the fixation of the display panel 30.

[0057] Figure 6 is a cross-sectional view of the mating portion between the flexible circuit board and the lamp cover portion provided in the second embodiment. As Figure 6 shown, the light-shielding tape 40 includes a first tape layer 41, a second tape layer 42, and a third tape layer 43. The first tape layer 41 is attached to the upper side of the lamp cover portion 113, the second tape layer 42 is attached to the upper side of the first tape layer 41, a first avoidance groove 421 is provided on the second tape layer 42, the part of the flexible circuit board 132 located on the upper side of the lamp cover portion 113 is accommodated in the first avoidance groove 421, and the third tape layer 43 is attached to the upper sides of the second tape layer 42 and the flexible circuit board 132 and is bonded to the display panel 30. That is to say, when the thickness of the display device permits, setting the third tape layer 43 can cover the assembly gap between the first avoidance groove 421 and the flexible circuit board 132, improving the light-shielding effect.

[0058] Embodiment 2

[0059] This embodiment provides a display device, whose general structure is the same as that in Embodiment 1, except for the shape of the flexible circuit board 132. Specifically as follows:

[0060] As Figure 7 is a partial cross-sectional view of the display device provided in this embodiment. Figure 8 is a bottom view of the partial structure of the display device provided in this embodiment. As Figure 7 and Figure 8 shown, the projection of the second end of the flexible circuit board 132 located outside the backplane 11 on the plane where the bottom plate portion 111 is located is a straight line. For some narrow-bezel display devices, the size of the circuit board 20 needs to be further compressed, and the placement space for components on the circuit board 20 is also correspondingly reduced. By setting the part of the flexible circuit board 132 located outside the backplane 11 as a straight line, the occupied space of the flexible circuit board 132 on the circuit board 20 can be reduced, enabling other components on the circuit board 20 to be arranged more reasonably. Specifically, comparing Figure 4 and Figure 6It can be seen that setting the portion of the flexible circuit board 132 outside the backplane 11 as a straight line can avoid the flexible circuit board 132 occupying the area of the circuit board 20 corresponding to the dimension D, and usually the dimension D is not less than 10 mm.

[0061] As Figure 7 and Figure 8 shown, the light strip assembly 13 further includes a pulling belt 133. One end of the pulling belt 133 is connected to the side (i.e., the lower side) of the second end of the flexible circuit board 132 close to the bottom plate portion 111, and the other end is attached to the lower side of the bottom plate portion 111. By providing the pulling belt 133, the convenience of assembling the flexible circuit board 132 can be improved, and attaching the pulling belt 133 to the lower side of the bottom plate portion 111 ensures that the pulling belt 133 has sufficient holding length and does not interfere with other components in the display device. Preferably, an avoidance opening is provided on the covering layer 50, and the portion of the pulling belt 133 attached to the lower side of the bottom plate portion 111 is received in the avoidance opening. Therefore, the lower surface of the pulling belt 133 can be substantially flush with the lower surface of the covering layer 50, avoiding an increase in the thickness of the backlight module 10 caused by the pulling belt 133.

[0062] As Figure 7 shown, a second avoidance groove 21 is provided at one end of the circuit board 20 close to the backplane 11. The second avoidance groove 21 is used to avoid the flexible circuit board 132, thereby preventing the flexible circuit board 132 from being worn due to a large acting force generated after continuous bending with the circuit board 20, and improving the service life of the display device.

[0063] Embodiment III

[0064] This embodiment provides a display device, which has a substantially the same structure as the display device in Embodiment II, except for the way the flexible circuit board 132 is led out from the upper side of the backplane 11, which is specifically as follows:

[0065] Figure 9 is a partial cross-sectional view of the display device provided in this embodiment, Figure 10 is a top view of the partial structure of the display device provided in this embodiment. As Figure 9 and Figure 10As shown, a notch portion 1131 is formed on the lamp cover portion 113. The first end of the flexible circuit board 132 is lapped on the upper side of the light guide plate 12, and the lamp strip 131 is disposed on the lower side of the first end of the flexible circuit board 132. The second end of the flexible circuit board 132 extends out of the back plate 11 from the notch portion 1131, that is to say, the flexible circuit board 132 is led out of the back plate 11 from the upper side of the side plate portion 112 corresponding to the notch portion 1131. It should be noted that the setting of the notch portion 1131 will affect the strength of the back plate 11 to a certain extent. However, since the required structural strength of the back plate 11 at the lamp cover portion 113 is lower than that at the intersection of the bottom plate portion 111 and the side plate portion 112, the notch portion 1131 is provided at the lamp cover portion 113 to meet the overall structural strength requirements of the backlight module 10. In addition, after the notch portion 1131 is provided, the flexible circuit board 132 can directly extend out of the back plate 11 from the notch portion 1131 without continuous bending, which is not only convenient for assembly but also beneficial to improving the service life of the flexible circuit board 132.

[0066] Preferably, the optical film 14 includes several layers of films, and at least one layer of film is provided with a lug portion 141. The lug portion 141 extends into the notch portion 1131 and is lapped on the flexible circuit board 132. The upper surface of the lug portion 141 is flush with the upper surface of the lamp cover portion 113. That is to say, by providing the lug portion 141, the height of the notch portion 1131 can be filled, the thickness difference between the flexible circuit board 132 and the lamp cover portion 113 can be compensated, and the upper surface of the lug portion 141 is flush with the upper surface of the lamp cover portion 113, so as to support the display panel 30 more flatly. On the contrary, the notch portion 1131 can limit the optical film 14 to prevent the optical film 14 from jumping off during use and avoid abnormal noise of the display device.

[0067] In some embodiments, the lug portion 141 and the flexible circuit board 132 can also be connected by a light-shielding tape, thereby reducing the light leakage problem here.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention and are not intended to limit the embodiments of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific embodiments and application scopes. The content of this specification should not be construed as a limitation to the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
