The housing 110 has an inner cavity 130, the light guide layer 120 is disposed in the inner cavity 130 of the housing 110, the housing 110 and the light guide layer 120 define a groove 140 located outside the light guide layer 120, and the groove 140 has a front opening 141.
However, in the process of manufacturing the backlight module 100, since the front port 141 of the groove 140 is an open port, external foreign matters easily pass through the front port 141 and enter the groove 140, which affects the normal operation of the backlight source (not shown) of the backlight module 100, thereby reducing the product yield of the backlight module 100.
In view of the above technical problems, a first embodiment of the present application provides a backlight module 100, as shown in fig. 5-6, the backlight module 100 includes a housing 110, a light guide layer 120, and a light shielding member 130. 3 the 3 light 3 guide 3 layer 3 120 3 may 3 be 3 composed 3 of 3 a 3 light 3 guide 3 plate 3 and 3 a 3 plurality 3 of 3 optical 3 films 3, 3 and 3 is 3 used 3 to 3 convert 3 light 3 emitted 3 from 3 a 3 backlight 3 source 3 ( 3 not 3 shown 3) 3 inside 3 the 3 backlight 3 module 3 100 3 into 3 a 3 surface 3 light 3 source 3, 3 so 3 that 3 light 3 incident 3 from 3 two 3 sides 3 of 3 the 3 sectioning 3 line 3 a 3- 3 a 3 is 3 uniformly 3 spread 3 on 3 the 3 end 3 surface 3 of 3 the 3 light 3 guide 3 layer 3 120 3. 3 The housing 110 includes a bottom plate 111 and a side frame 112 disposed at a peripheral edge of the bottom plate 111, wherein the bottom plate 111 and the side frame 112 together define an internal chamber 140. The light guide layer 120 is disposed in the internal cavity 140 and abuts against the bottom plate 111 of the housing 110. The light guide layer 120 and the side frame 112 together define a groove 150 located outside the light guide layer 120, and the groove 150 has an end face opening 151 departing from the bottom plate 111. One side of the light shielding member 130 is connected to the end of the side frame 112 away from the bottom plate 111, and the other side is connected to the end face of the light guiding layer 120 away from the bottom plate 111 to cover the end face opening 151.
In this embodiment, one side of the light shielding member 130 is connected to the end of the side frame 112 away from the bottom plate 111, and the other side of the light shielding member 130 is connected to the end surface of the light guiding layer 120 away from the bottom plate 111, so that the light guiding layer 120 is fixedly connected to the housing 110 by the light shielding member 130. And the light-shielding member 130 can cover the end face opening 151 of the groove body 150, so that the internal space of the groove body 150 can be isolated from the space outside the groove body 150, and external foreign matters are prevented from penetrating through the end face opening 151 to enter the groove body 150, thereby preventing the external foreign matters from polluting the backlight source inside the backlight module 100, and improving the product yield and the user experience during the manufacturing of the backlight module 100.
In the backlight module 100, whether the light-shielding member 130 can effectively cover the end face opening 151 of the slot 150 is directly related to the product yield of the backlight module 100. In this embodiment, the bottom plate 111 may be rectangular, the side frame 112 includes four frame strips located on the outer periphery of the light guide layer 120, the four frame strips are sequentially connected end to end, and the four frame strips include a first frame strip 1121, and the first frame strip 1121 includes a top surface 11211 deviating from the bottom plate 111. One side of the light shielding member 130 is attached to the top surface 11211, and the other side is attached to the edge of the surface of the light guiding layer 120 away from the bottom plate 111.
The light shielding member 130 may be in a shape of a long strip, and a length direction of the light shielding member 130 is parallel to a length direction of the first frame strip 1121. Along the length direction of the first frame strip 1121, the length of the light shielding member 130 is at least equal to the side length of the light guiding layer 120.
It should be noted that, in the present embodiment, both the bottom plate 111 and the light shielding member 130 may have any shape, for example, the bottom plate 111 may have a circular shape, an angular shape, or the like, and the light shielding member 130 may have a regular shape or an irregular shape. The present embodiment does not limit the specific shapes of the bottom plate 111 and the light shielding member 130, and is only used for illustrative purposes to clearly describe the technical solution of the present embodiment.
In the above embodiment, the light shielding member 130 in a long strip shape can completely cover the end face opening 151 of the slot body 150, so as to completely isolate the internal space of the slot body 150 from the space outside the slot body 150, thereby avoiding the risk of external foreign matters entering the slot body 150.
The connection reliability between the light-shielding member 130 and the first frame strip 1121 affects the product quality of the backlight module 100. As shown in fig. 6, in the present embodiment, the thickness of the first frame strip 1121 may be 0.1 mm. The light shielding member 130 may include a first attaching portion 131, the first attaching portion 131 is attached to the top surface 11211 of the first frame strip 1121, and a width of the first attaching portion 131 is at least 0.1 mm along a direction of the light guiding layer 120 pointing to the first frame strip 1121.
When the thickness of the first frame strip 1121 is 0.1 mm, the frame of the display device assembled with the backlight module 100 of this embodiment can be narrowed. In addition, when the width of the first attaching portion 131 of the light shielding member 130 is at least 0.1 mm along the direction in which the light guide layer 120 points to the first frame strip 1121, the first attaching portion 131 can completely cover the top surface 11211 of the first frame strip 1121, so as to improve the connection strength between the light shielding member 130 and the first frame strip 1121.
In the process of manufacturing the backlight module 100, there is an assembly error in the process of installing the light guide layer 120 and the housing 110. As shown in fig. 7, in the second embodiment of the present application, the light shielding member 130 includes a protruding portion 132. The extending portion 132 is located on a side of the first frame strip 1121 that deviates from the light guide layer 120, and is connected to a side of the first attaching portion 131. Along the direction that the light guide layer 120 points to the first frame strip 1121, the width of the protrusion 132 is at least 0.08 mm.
Generally, the assembly tolerance of the light guide layer 120 of the backlight module 100 and the housing 110 is 0.12mm, and when the width of the first attaching portion 131 of the light shielding member 130 is 0.1 mm and the width of the extending portion 132 is 0.8 mm, the sum of the widths of the first attaching portion 131 and the extending portion 132 is 1.8 mm. Therefore, under the condition that the maximum assembly error is 1.2 mm, the width dimension of the light shielding member 130 attached to the top surface 11211 of the first frame strip 1121 is still 0.06mm, so as to effectively ensure the connection strength between the light shielding member 130 and the first frame strip 1121.
Similarly, the connection reliability between the light shielding member 130 and the light guiding layer 120 is directly related to the product reliability of the backlight module 100. In this embodiment, the light shielding member 130 includes a second attaching portion 133, the second attaching portion 133 is attached to the edge of the surface of the light guiding layer 120 away from the bottom plate 111, and the width of the second attaching portion 133 is at least 0.15 mm along the direction in which the first frame strip 1121 points to the light guiding layer 120.
When the width of the second attaching portion 133 of the light shielding member 130 is 0.15 mm, the frame of the display device assembled with the backlight module 100 of this embodiment can be narrowed, and the light shielding member 130 is effectively and fixedly connected to the light guiding layer 120, so that the risk of separation between the light shielding member 130 and the light guiding layer 120 is avoided, and the reliability of the backlight module 100 is improved.
As shown in fig. 8, in this embodiment. For convenience of describing the technical solution of the present embodiment, the technical solution of the present application is described with reference to five dimensional parameters, i.e., a, b, c, d and e. The width dimension of the first attaching portion 131 of the light blocking member 130 is denoted by a. The width dimension of the extension 132 of the light blocking member 130 is denoted by b. The width dimension of the second attaching portion 133 of the light blocking member 130 is denoted by c. d is used to indicate a distance from a surface edge of the light guide layer 120 departing from the bottom plate 111 to an inner side surface of the first frame strip 1121 in a direction in which the light guide layer 120 points to the first frame strip 1121. e is used to indicate a distance from an edge of the light shielding member 130, which is connected to the surface of the light guiding layer 120 away from the bottom plate 111, to the display area dividing line B-B in a direction in which the first frame strip 1121 points to the light guiding layer 120. The display area dividing line B-B is a boundary line between a display area (not shown) and a non-display area of the liquid crystal panel disposed on the end of the light guide layer 120 away from the bottom plate 111.
Where d may be 0.12mm and e may be 0.23 mm. When d is 0.12mm, a safe distance may be formed between the light guide layer 120 and the first frame strip 1121, so as to avoid the risk of the light guide layer 120 from generating film wrinkles. And e is 0.23 mm, the LCD pixels can be prevented from being shielded at the joint of the light shielding member 130 and the surface of the light guiding layer 120 away from the bottom plate 111.
The five dimensional parameters a, b, c, d and e in the above embodiments are only preferred parameters listed in the present embodiment, and all have the same or similar structure as that in the present embodiment, so as to realize that the light shielding member 130 covers the end face opening 151 of the backlight module 100, and the technical scheme for isolating external foreign objects from entering the interior of the slot body 150 is within the protection scope of the present embodiment.
