DETAILED DESCRIPTION

[0039] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure, and different embodiments may be combined arbitrarily without conflict. Therefore, the drawings and descriptions are considered to be illustrative in nature and not restrictive.

[0040] Figure 1 FIG. 1 is a schematic top view of a display device in the related art, in which an optical film material 13 and a back plate 11 are shown. Figure 2A for Figure 1 AA section diagram of the positioning lug area, Figure 2B for Figure 1 BB cross-section diagram of the non-locating lug area. Figure 1 , Figure 2A and Figure 2B As shown, the display device includes a light-emitting module and a liquid crystal display panel 20, and the liquid crystal display panel 20 is located on the light-emitting side of the light-emitting module. The light-emitting module includes a back plate 11, and the back plate 11 includes a bottom wall 111 and a side wall 112, and the side wall 112 is arranged at the outer edge of the bottom wall 111. Generally, the side wall 112 can be continuously arranged along the outer edge of the bottom wall 111. The inner side of the side wall 112 forms a receiving cavity. The side wall 112 is provided with a plurality of notches 113. The light-emitting module also includes a backlight unit 12 and an optical film material 13. The backlight unit 12 is located in the receiving cavity. As shown Figure 2A and Figure 2B As shown, the optical film 13 is located on the upper side of the backlight unit 12. Figure 1 As shown, the optical film 13 includes a film body 13a and a positioning lug 13b, and the positioning lug 13b is formed by extending outward from the outer edge of the film body 13a. When the optical film 13 is arranged on the upper side of the backlight unit 12, the positioning lug 13b is confined in the notch 113 to limit the optical film 13.

[0041] It should be noted that the surface of the back plate 11 is usually provided with a coating, and the coating material includes zinc, so the surface of the back plate 11 has the function of reflecting light. The plastic frame 14 is usually black and has the function of absorbing light.

[0042] like Figure 2B As shown, in the non-positioning lug area, the film body 13a is located inside the side wall 112 of the back plate 11, and the light emitted from the side of the film body 13a is reflected by the side wall 112 and then emitted from the edge of the plastic frame 14, making the non-positioning lug area bright. Figure 2A As shown, in the positioning lug area, the light emitted from the side of the positioning lug 13b is absorbed by the plastic frame 14, so that the light emitted from the side of the positioning lug 13b cannot be emitted from the edge of the plastic frame 14, causing the positioning lug area to be dark. Therefore, there is a brightness difference between the positioning lug area and the non-positioning lug area, so that a dark line is formed in the positioning lug area. When viewed from the front angle, the dark line is slight; when viewed from the side angle, the brightness difference between the positioning lug area and the non-positioning lug area is large, the dark line is obvious, and a dark line (Dark edge) defect is formed.

[0043] When the viewing angle requirement of the display product is not high, such as MNT products, poor dark lines will not affect the market satisfaction of the product; when the viewing angle requirement of the display product is high, such as TPC products, poor dark lines will seriously affect the market satisfaction of the product.

[0044] In order to improve the market satisfaction of display products, the embodiments of the present disclosure provide a light-emitting module and a display device.

[0045] Figure 3 is a cross-sectional schematic diagram of a display device in an embodiment of the present disclosure. In the embodiment of the present disclosure, the top view schematic diagram of the display device can be as follows Figure 1 As shown, Figure 3 Can be Figure 1 AA cross-sectional view of the embodiment of the present disclosure. Figure 1 and Figure 3 As shown, the display device may include a light emitting module and a liquid crystal display panel 20. The liquid crystal display panel 20 is located at the light emitting side of the light emitting module. Figure 3 In the embodiment, the liquid crystal display panel 20 is located on the upper side of the light emitting module. The light emitting module includes a back plate 11, a backlight unit 12, an optical film material 13 and a plastic frame 14.

[0046] The back panel 11 includes a bottom wall 111 and a side wall 112, and the side wall 112 is arranged at the outer edge of the bottom wall 111. Exemplarily, the side wall 112 can be arranged along the outer edge of the bottom wall 111. The inner side of the side wall 112 forms a receiving cavity, and the side wall 112 is provided with at least one notch 113. The backlight unit 12 is located in the receiving cavity. The optical film 13 is located on the side of the backlight unit 12 away from the bottom wall 111, and the optical film 13 includes a film body 13a and a positioning lug 13b extending outward from the edge of the film body 13a, and the positioning lug 13b is confined in the notch 113 to limit the optical film 13, such as Figure 1 and Figure 3 shown.

[0047] The plastic frame 14 includes a support frame portion 141 and a peripheral wall 142. The support frame portion 141 is located on the side of the side wall 112 and the optical film material 13 away from the bottom wall 111. The peripheral wall 142 is arranged along the outer edge of the support frame portion 141 and surrounds the outer side of the back plate 11. The inner surface of the plastic frame 14 is provided with a reflective film 40 for reflecting the light emitted from the positioning lug 13b. The surface of the peripheral wall 142 facing the back plate 11 includes a first surface portion. The reflective film 40 includes a first reflective portion 41, and the first reflective portion 41 is located on the first surface portion.

[0048] In the technical solution disclosed in the present invention, the peripheral wall 142 is opposite to the side of the positioning lug 13b, and the surface of the peripheral wall 142 facing the back plate 11 includes a first surface portion, and the first surface portion is provided with a first reflective portion 41. The reflective film 40 is used to reflect the light emitted from the positioning lug 13b. Therefore, by providing the first reflective portion 41 on the first surface portion, the first reflective portion 41 can reflect the light emitted from the side of the positioning lug 13b, so that the light is emitted from the edge of the plastic frame 14 in the positioning lug area, thereby improving the brightness of the positioning lug area, compensating for the brightness difference between the positioning lug area and the non-positioning lug area, improving the dark line defect in the positioning lug area, and reducing the defective rate of the product from 100% to 0; and improving the picture quality of the product, broadening the scope of use of the product, and improving the market satisfaction of the product.

[0049] In one embodiment, the reflectivity of the reflective film 40 to light can be greater than or equal to 88%, so that the first reflective portion 41 can reflect more light emitted from the side of the positioning lug 13b, so that more light is emitted from the edge of the rubber frame 14 in the positioning lug area, further improving the brightness of the positioning lug area and improving dark line defects.

[0050] Exemplarily, the luminous film may be a reflective material layer. For example, a reflective material layer may be formed on the first surface portion, and the reflective material layer may serve as the first light reflecting portion 41 .

[0051] In another example, the reflective film 40 may include a white tape. For example, a white tape is attached to the first surface portion as the first reflective portion 41. The white tape may include a white reflective layer and an adhesive layer, and the material of the white reflective layer may include polyethylene terephthalate (PET). The thickness of the white reflective layer is about 0.1 mm, and the thickness of the adhesive layer is about 0.05 mm.

[0052] Figure 4 FIG. 1 is a schematic diagram of the position of the notch in the light-emitting module according to an embodiment of the present disclosure. Figure 4As shown, the positive projection of the positioning lug 13b on the first reflective portion 41 can be located inside the first reflective portion 41. The difference between the length L1 of the first reflective portion 41 and the length L2 of the positioning lug 13b can be greater than or equal to 2 mm. The width W1 of the first reflective portion 41 is greater than or equal to 1 mm. The length is the dimension along the outer edge direction of the support frame portion 141, and the width is the dimension in the direction perpendicular to the bottom wall 111. Figure 4 In the figure, the length is the dimension in the horizontal direction, and the width is the dimension in the vertical direction. For example, the length of the first reflective portion 41 / positioning lug 13b is the dimension of the first reflective portion 41 / positioning lug 13b along the outer edge direction of the support frame portion 141, and the width of the first reflective portion 41 is the dimension of the first reflective portion 41 in the direction perpendicular to the bottom wall 111.

[0053] The difference between the length of the first reflecting portion 41 and the length of the positioning lug 13b is set to be greater than or equal to 2 mm, which can avoid the misalignment of the first reflecting portion 41 and the positioning lug 13b caused by the attachment fluctuation, and ensure that the positive projection of the positioning lug 13b on the first reflecting portion 41 in the length direction is located within the first reflecting portion 41, so that the first reflecting portion 41 can reflect more light emitted from the side of the positioning lug 13b, further increase the reflection amount of the emitted light, enhance the brightness of the positioning lug area, and improve the dark line defects.

[0054] Exemplarily, the length of the first reflective portion 41 may be greater than the length of the notch 113 , so that all light emitted from the notch 113 can be reflected by the first reflective portion 41 , further improving the brightness of the positioning lug area and improving dark line defects.

[0055] In one embodiment, Figure 3 As shown, the optical film material 13 may include a diffuser, a prism sheet, and a brightness enhancement film which are stacked in sequence. The diffuser sheet faces the backlight unit 12. The prism sheet may include a first prism sheet, and the brightness enhancement film may include a reflective polarized brightness enhancement film. Such an optical film material 13 has less light emitted from the edge, and the brightness difference between the positioning lug area and the non-positioning lug area is small. The width of the first reflective portion 41 is set to be greater than or equal to 1 mm, which can make up for the brightness difference between the positioning lug area and the non-positioning lug area and improve the poor dark line in the positioning lug area.

[0056] Exemplarily, the width of the first reflective portion 41 may be greater than the width of the notch 113 , so that the light emitted from the notch 113 may be reflected by the first reflective portion 41 , further improving the brightness of the locating lug 13 b and improving dark line defects.

[0057] Figure 5It is a cross-sectional schematic diagram of a display device in another embodiment of the present disclosure. In practical applications, the width of the first reflective portion 41 can be set according to the thickness of the optical film material 13. For example, the width of the first reflective portion 41 can be greater than or equal to 2 mm. Exemplarily, the prism sheet may include a first prism sheet and a second prism sheet, so that the optical film material 13 may include a diffuser, a first prism sheet, a second prism sheet and a brightness enhancement film that are stacked in sequence. Such an optical film material 13 has more light emitted from the edge, so that the brightness difference between the positioning lug area and the non-positioning lug area is large. Setting the width of the first reflective portion 41 to be greater than or equal to 2 mm can make the first reflective portion 41 reflect more light emitted from the side of the positioning lug 13b, so that more light is emitted from the edge of the rubber frame 14 in the positioning lug area, further improving the brightness of the positioning lug area, compensating for the brightness difference between the positioning lug area and the non-positioning lug area, and improving the poor dark line in the positioning lug area.

[0058] In one embodiment, Figure 5 As shown, the edge of the first light reflecting portion 41 close to the bottom wall 111 (at Figure 5 The bottom edge of the first light reflecting portion 41 in the middle is close to the bottom wall 111 relative to the bottom surface of the notch 113. In this way, the light emitted downward from the notch 113 can be received and reflected by the first light reflecting portion 41, further improving the brightness of the positioning lug area and improving the dark line defect.

[0059] Figure 6 FIG. 4 is a cross-sectional schematic diagram of a display device in another embodiment of the present disclosure. In order to further improve the brightness of the positioning lug area, in one embodiment, as shown in FIG. Figure 6 As shown, the reflective film 40 may further include a second reflective portion 42, and the second reflective portion 42 is located on the surface of the support frame portion 141 on the side facing the optical film material 13. The second reflective portion 42 may be connected to the first reflective portion 41. In such a reflective film 40, the light reflected upward by the first reflective portion 41 may be reflected again by the second reflective portion 42, and the second reflective portion 42 may also reflect the light emitted from the upper surface of the positioning lug 13b, thereby preventing the light from being absorbed by the plastic frame 14, so that more light is emitted from the edge of the plastic frame 14 in the positioning lug area, further improving the brightness of the positioning lug area, compensating for the brightness difference between the positioning lug area and the non-positioning lug area, and improving the dark line defect.

[0060] For example, Figure 6 As shown, the second reflective portion 42 can be connected to the first reflective portion 41. Figure 6 It can be seen that the second reflective portion 42 and the first reflective portion 41 can be connected into an integrated structure, so that the reflective film 40 can reflect more light and improve the dark line defect.

[0061] Exemplarily, the orthographic projection of the positioning lug 13b on the second light reflecting portion 42 may be located within the second light reflecting portion 42, so that the second light reflecting portion 42 may reflect more light, further improving the brightness of the positioning lug area and improving dark line defects.

[0062] Figure 7 FIG. 1 is a schematic top view of an optical film material in one embodiment of the present disclosure. Figure 5 and Figure 7 As shown, the optical film 13 may include a diffuser facing one side of the backlight unit 12. The backlight unit 12 includes a light guide plate 121, and a light shielding strip 50 is provided on the surface of the diffuser along the outer edge of the light guide plate 121, and a preset distance is provided between the light shielding strip 50 and the outer edge of the light guide plate 121. The preset distance can be set as needed and is not limited here.

[0063] like Figure 7 As shown, the light shielding belt 50 includes a first belt portion 51 corresponding to the positioning lug 13b and a second belt portion 52 outside the first belt portion 51, and the width of the first belt portion 51 is smaller than the width of the second belt portion 52. The width of the first belt portion 51 corresponding to the positioning lug 13b is smaller than the width of the second belt portion 52 at other positions, so that the positioning lug area can emit more light to the reflective film 40 and be reflected by the reflective film 40, thereby allowing more light to be emitted from the edge of the plastic frame 14 in the positioning lug area, further improving the brightness of the positioning lug area and improving the dark line defect.

[0064] In one embodiment, the width of the first belt portion 51 may be b, and the width of the second belt portion 52 may be a, and b may be 1 / 4 to 1 / 2 of a, that is, b=a*1 / 4 to a*1 / 4. For example, a may be 1.0 mm to 1.2 mm, such as a is 1.1 mm; b may be 0.4 mm to 0.6 mm, such as b is 0.5 mm.

[0065] like Figure 7 As shown, the inner edges of the first belt portion 51 and the second belt portion 52 are flush. It can be understood that the inner side of the shading belt 50 is used for display, and setting the inner edges of the first belt portion 51 and the second belt portion 52 to be flush can ensure that the shape of the display area is regular. In addition, setting the inner edges of the first belt portion 51 and the second belt portion 52 to be flush can relatively increase the area of ​​the positioning lug area, so that more light in the positioning lug area is reflected by the reflective film, further improving the brightness of the positioning lug area and improving the dark line defect.

[0066] like Figure 5As shown, the optical film material 13 may include a diffuser, a prism sheet, and a brightness enhancement film stacked in sequence, and the diffuser faces the backlight unit 12. The shading strip 50 may be located on the surface of the diffuser, for example, the shading strip 50 may be disposed on the surface of the diffuser facing the backlight unit 12, or may be disposed on the surface of the diffuser facing the prism sheet. For example, the shading strip 50 may be formed by printing black ink on the surface of the diffuser using an ink printing process.

[0067] Understandably, Figure 7 The light shielding tape 50 shown can also be applied to Figure 3 and Figure 6 In the embodiment, the brightness of the positioning lug area is further improved and the dark line defect is improved.

[0068] refer to Figure 3 , Figure 5 and Figure 6 , the surface of the peripheral wall 142 facing the back plate 11 may also include a second surface portion. The second surface portion is protruded relative to the first surface portion toward the back plate 11. The first surface portion is located between the second surface portion and the support frame portion 141. The difference between the width of the first surface portion and the width of the first reflective portion 41 is greater than or equal to 0.2 mm. Thus, the first surface portion can provide sufficient space for the first reflective portion 41, and tolerance fluctuations are taken into account to ensure that the first reflective portion 41 can be completely attached to the first surface portion.

[0069] exist Figure 5 and Figure 6 In the embodiment, the width of the first light reflecting portion 41 is larger. In order to provide sufficient space for the first light reflecting portion 41, Figure 5 and Figure 6 The width of the first surface portion is greater than Figure 3 The width dimension of the first surface portion.

[0070] refer to Figure 1 and Figure 3 , the backlight unit 12 may include a light guide plate 121 and a light source (not shown in the figure) located on one side of the light guide plate 121. The side wall 112 of the back plate 11 includes a first partition wall 112a corresponding to the light source and a second partition wall 112b located outside the first partition wall 112a. The notch 113 is provided on the second partition wall 112b. Exemplarily, the side wall 112 of the back plate 11 may be a quadrilateral, the second partition wall 112b may be three sides of the side wall 112, and the notches 113 may be provided on all three sides of the second partition wall 112b. The number of the notches 113 may be set as needed, and the positioning lugs 13b may correspond one to one with the notches 113.

[0071] The backlight unit 12 may further include a reflective sheet 122 , and the reflective sheet 122 is located between the light guide plate 121 and the bottom wall 111 .

[0072] refer to Figure 3 The light-emitting module may further include a light-shielding tape 15, which is pasted on the outer surface of the bottom wall 111 of the back panel 11 and extends to the outer surface of the outer wall 142 of the frame 14. The light-shielding tape 15 corresponds to the positioning lug 13b. The light-shielding tape 15 is used to prevent light from leaking out from the gap between the frame 14 and the back panel 11 to avoid light leakage.

[0073] The light-emitting module of the embodiment of the present disclosure can be assembled in a display device as a backlight source, and can also be used as a light source in lighting products.

[0074] The present disclosure also provides a light-emitting device, including the light-emitting module in any embodiment of the present disclosure. For example, the light-emitting device may be a display device, such as Figure 3 As shown, the display device may further include a liquid crystal display panel 20, which may be located at the light-emitting side of the light-emitting module. A support cotton 30 may be provided between the liquid crystal display panel 20 and the plastic frame 14, and the support cotton 30 may be foam.
