FIG. 1A shows a schematic diagram of an exemplary display module 100.

As shown in FIG. 1A , the display module 100 may include a display panel 102 and a backlight module 104 . The display panel 102 is disposed on the light exit side of the backlight module 104 , and the backlight module is used to provide backlight for the display panel 102 . In order to fix the relative positions of the display panel 102 and the backlight module 104, an adhesive tape 106 is also provided on the display panel 102 and the backlight module 104. As shown in FIG. 1A, the adhesive tape covers the sides of the display panel 102 and the backlight module 104. , plays a fixed role.

In some exemplary embodiments, the display panel 102 may further include a first substrate 1022 and a second substrate 1024. Relative to the second substrate 1024, the first substrate 1022 is close to the backlight module 104. In an exemplary embodiment, the first polarizing layer 1026 is disposed on the side of the first substrate 1022 facing the backlight module 104 , and the second polarizing layer 1028 is disposed on the side of the second substrate 1024 away from the backlight module 104 . The first substrate 1022 and the second substrate 1024 may be array substrates or color filter substrates. For example, the first substrate 1022 may be an array substrate, and the second substrate 1024 may be a color filter substrate.

In some exemplary embodiments, as shown in FIG. 1A , the backlight module 104 may further include a backplane 1042 and a light emitting component 200 . As shown in FIG. 1A , the back plate 1042 may further include a bottom plate (the horizontal part of the back plate 1042 in FIG. 1A ) and a side plate perpendicular to the bottom plate (the vertical part of the back plate 1042 in FIG. 1A ), and a light emitting component. 200 can be set on this base plate.

FIG. 2A shows a schematic diagram of light source distribution of a light panel of an exemplary lighting assembly 200 according to an embodiment of the present disclosure. As shown in FIG. 2A, the lighting assembly 200 may include a light panel. The light panel may further include a substrate 204 and light emitting units 206 (backlight) arranged in an array on the substrate 204. In some exemplary embodiments, the light-emitting unit 206 may be a light-emitting diode, a sub-millimeter light-emitting diode (Mini LED) or a micron light-emitting diode (Micro LED).

In some exemplary embodiments, considering the performance differences of LEDs of different colors, blue Mini LEDs with relatively long lifespan may be selected as the light-emitting unit 206. On this basis, a light conversion film can be provided on the light exit side of the light-emitting unit 206 to convert part of the blue light into red light and green light to emit white light under the mixture of the three-color light.

FIG. 2B shows a schematic diagram of a hierarchical structure of an exemplary light emitting assembly 200 according to an embodiment of the present disclosure. As shown in FIG. 2B , along the light emission direction 202 of the backlight module 104 , the light-emitting component 200 may include a substrate 204 , a blue miniLED 206 , a light conversion film 208 , a uniform light film/diffusion film 210 , and a prism film 212 arranged in sequence.

In some exemplary embodiments, the light conversion film 208 may be a phosphor conversion film or a quantum dot conversion film. The phosphor conversion film may include phosphor for emitting yellow light under excitation of the blue light. The quantum dot conversion film may include first quantum dots configured to emit red light under the excitation of the blue light and second quantum dots configured to emit green light under the excitation of the blue light.

FIG. 2C shows a partially enlarged schematic diagram of an exemplary light conversion film 208 according to an embodiment of the present disclosure. As shown in FIG. 2C , first quantum dots 2082 and second quantum dots 2084 may be distributed in the light conversion film 208 , wherein the first quantum dots 2082 may be excited by the blue light emitted by the light-emitting unit 206 To emit red light, the second quantum dots 2084 may emit green light under the stimulation of the blue light emitted by the light emitting unit 206 . In this way, using quantum dots to convert blue light into red or green light can make the color purity of the emitted light higher.

Returning to FIG. 2A, it can be seen that the light-emitting component 200 can be divided into a first light-emitting area 200a and a second light-emitting area 200b, wherein the dotted frame 200c schematically separates the two light-emitting areas and the second light-emitting area 200b surrounds around the first light-emitting area 200a. It can be seen from FIG. 2B that the first light-emitting area 200a may be located at the center of the light-emitting component 200, and the second light-emitting area 200b may be located at the edge of the light-emitting component 200. The first light-emitting area 200a may include a plurality of light-emitting units 206, for example, the light-emitting unit 206a; the second light-emitting area 200b may also include a plurality of light-emitting units 206, for example, the light-emitting units 206b and 206c.

It can be seen from FIG. 2B and FIG. 2C that any light-emitting unit located in the non-edge area of the light-emitting component 200, for example, the light-emitting unit 206a of FIG. 2B, will be affected by the surrounding light-emitting units, such as the light-emitting unit 206b of FIG. 2B. , 206c light 2062 (shown in Figure 2C) radiates. Therefore, the quantum dots 2082 and 2084 in the light conversion film 208 in the light emitting direction of the light emitting unit 206 located in the non-edge area of the light emitting component 200 can be relatively fully excited, so that white light can be emitted after passing through the light conversion film 208 Effect. However, any light-emitting unit located in the edge area of the light-emitting component 200 has less area radiated by light from its surrounding light-emitting units than the light-emitting unit located in the non-edge area. As a result, the light-emitting unit 206 located at the edge of the light-emitting component 200, For example, after the blue light emitted by the light-emitting units 206b and 206c in FIG. 2B is incident on the light conversion film 208, the quantum dots 2082 and 2084 are excited to produce yellow light (a mixed light of red light and green light) compared to the non-edge area. Therefore, when viewed from the side of the light conversion film 208 away from the light-emitting unit, there will be a circle of blue light surrounding the white light, which is hereinafter referred to as the blue edge. In addition, the edge of the quantum dot conversion film 208 is also prone to failure, which is also one of the reasons for the blue edge phenomenon. The blue edge problem usually causes the display effect of the LCD device in the area corresponding to the blue edge. For example, the area corresponding to the blue edge is lower in brightness and bluer in color than other areas.

Therefore, when designing the display module 100, the problem of blue light leakage needs to be considered.

Returning to FIG. 1A , it can be seen that the backlight module 104 also includes a plastic frame 1044 for providing support for the display panel 102 . The plastic frame 1044 is usually disposed on the inner surface of the side plate of the back plate 1042, so it occupies the internal space of the back plate 1042, thereby squeezing the space of the light emitting component 200 on the back plate 1042. cloth space. In other words, the light-emitting component 200 needs to shrink inward, causing the edges of the light-emitting component 200 to also shrink inward, so that the blue light generated in the edge area of the light-emitting component 200 will leak out from the display panel 102 . If you want to improve the blue light problem, you need to add other additional processes, resulting in increased costs and reduced efficiency.

FIG. 1B shows a schematic diagram of another exemplary display module 100.

As shown in FIG. 1B , the display panel 102 of the display module 100 is smaller in size than the display panel in FIG. 1A , so that the display panel also shrinks inward, which wastes a large amount of space inside the backplane and makes it difficult to achieve a narrow frame. And there is also the problem of blue light leakage.

In a possible exemplary implementation, the plastic frame 1044 can be replaced with a yellow plastic frame, and yellow tape is attached to the light panel to absorb leaked blue light, thereby preventing blue light leakage. However, this method requires consideration of the space for gluing. When the glue space is too narrow, it is not easy to attach the yellow tape, and monitors with narrow borders will encounter difficulties. When the non-display edge of the display panel is small, too much space is wasted, accompanied by the problem of blue light leakage.

Exemplary embodiments of the present disclosure provide a backlight module, including: a backplane, including a bottom panel and side panels perpendicular to the bottom panel; a light-emitting component disposed on the bottom panel; and an outer frame, covering the The side panel is located outside the back panel and is configured to support the display panel.

The backlight module does not need to occupy the internal space of the backplane by arranging an outer frame for supporting the display panel on the outside of the backplane, so that the edge of the light-emitting component can be as close as possible to the side panel of the backplane and away from the display area of the display panel. The problem of blue light leakage is solved to a certain extent, and the display effect is better.

As shown in FIG. 3A , the display module 300 may include a display panel 302 and a backlight module 304. The backlight module 304 may further include a backplane 3042, a light emitting component 3046, and an outer frame 3044 for supporting the display panel 302. The back panel 3042 may further include a bottom panel and a side panel perpendicular to the bottom panel. The light emitting component 3046 may be disposed on the bottom panel, and the outer frame 3044 may be covered on the side panel and located outside the back panel 3042 . In this way, by arranging an outer frame for supporting the display panel on the outside of the backplane, there is no need to occupy the internal space of the backplane, so that the size of the light-emitting component can be increased, and its edge can be as close as possible to the side panel of the backplane and away from the display panel. The display area can solve the problem of blue light leakage to a certain extent and the display effect is better. Moreover, because the internal space of the back panel is maximized, narrow bezels can also be achieved.

In an exemplary implementation, the light-emitting component 3046 may have a similar structure to the light-emitting component 200 and have corresponding technical effects, which will not be described again here.

In some exemplary embodiments, as shown in FIG. 3A , the outer frame 3044 may further include a first frame parallel to the bottom panel and a second frame parallel to the side panel, and the orthographic projection of the first frame on the bottom panel covers the side panel. The orthographic projection on the base plate, in other words, the size of the first frame along the extending direction of the base plate (horizontal direction in FIG. 3A ) is at least greater than or equal to the size of the side plate, thereby providing better support. As shown in FIG. 3A , the second frame can be located outside the side panel and fit with the side panel. In this way, the outer frame 3044 and the back plate 3042 achieve better cooperation. In some exemplary embodiments, double-sided tape may also be provided between the second frame and the side panel, so that the positions of the two can be better fixed.

In some exemplary embodiments, as shown in FIG. 3A , the orthographic projection of the display panel 302 in the bottom plate of the back plate 3042 partially overlaps the orthographic projection of the outer frame 3044 in the bottom plate of the back plate 3042 . In other words, the edge of the display panel 302 is placed on the outer frame 3044 so that the outer frame 3044 can support the display panel 302 .

The outer frame 3044 can be a plastic frame or a metal frame (for example, an iron frame). In some exemplary embodiments, when a metal frame is selected as the outer frame 3022, the thickness of the outer frame 3044 can be reduced, so that the thickness of the entire machine can be smaller. For example, when using a plastic frame, the thickness of the outer frame can be 0.3mm, while when using a metal frame, the thickness of the outer frame can be 0.15mm, thus almost reducing the thickness by half, and the effect is better.

In some exemplary embodiments, as shown in FIG. 3A , a light-shielding layer 3048 may also be provided between the back plate 3042 and the outer frame 3044 , for example, between the side plate of the back plate 3042 and the first frame of the outer frame 3044 A light shielding layer 3048 may be provided. The orthographic projection of the light-shielding layer 3048 on the base plate partially overlaps the orthographic projection of the light-emitting component 3046 on the base plate. For example, as shown in FIG. 3A , the light-shielding layer 3048 covers the edge of the light-emitting component 3046, thereby blocking the blue light leaking out at the edge.

In some exemplary embodiments, as shown in FIG. 3A , a yellow fluorescent material layer 3050 can also be provided on the side of the side plate of the back plate 3042 facing the light-emitting component 3046, so that blue light can be absorbed to a certain extent to further improve the problem of blue light leakage. .

In some exemplary embodiments, as shown in FIG. 3A , the display panel 302 may further include a first substrate 3022 and a second substrate 3024. Relative to the second substrate 3024, the first substrate 3022 is close to the backlight module 304. In an exemplary embodiment, the first polarizing layer 3026 is provided on the side of the first substrate 3022 facing the backlight module 304, and the first polarizing layer 3026 is provided on the side of the second substrate 3024 away from the backlight module 304. A second polarizing layer 3028 is provided. The first substrate 3022 and the second substrate 3024 may be array substrates or color filter substrates. For example, the first substrate 3022 may be an array substrate, and the second substrate 3024 may be a color filter substrate.

As shown in FIG. 3A , the first frame of the outer frame 3044 surrounds an opening 30442. The orthographic projection of the first polarizing layer 3026 in the bottom plate is the same as the orthographic projection of the outer frame 3044 in the bottom plate. There is no overlap, and the first polarizing layer 3026 is located in the opening 30442. By disposing the first polarizing layer 3026 in the opening 30442, the thickness of the entire device can be reduced, making the entire device thinner and lighter.

As an optional exemplary embodiment, as shown in FIG. 3B , the orthographic projection of the first polarizing layer 3026 in the base plate partially overlaps the orthographic projection of the outer frame 3044 in the base plate, so that the first polarized light The layer 3026 can be disposed on the outer frame 3044, thereby enhancing the strength of the entire machine and providing better support to the display panel 302.

In some exemplary embodiments, in order to fix the display panel 302 and the backlight module 304, a double-sided tape 306 is also disposed between the first substrate 3022 of the display panel 302 and the outer frame 3044 of the backlight module 304. As shown in FIG. 1A tape 106 can play a fixing role, and the bonding method is simpler, and the appearance is more streamlined and beautiful.

When making the above display module 300, the following steps can be adopted:

Attach yellow fluorescent tape 3050 to the inner side wall of the side panel of the back panel 3042, and attach double-sided tape to the outer side wall of the side panel of the back panel 3042.

A light shielding layer 3048 is attached to the inner wall of the first frame of the outer frame 3044.

Fix the light-emitting component 3046 in the back panel.

After confirming that there are no foreign objects, peel off the double-sided tape on the outside of the back plate 3042, and buckle the outer frame 3044 onto the back plate 3042.

The wording glue 306 is attached to the outer frame 3044 and fixed with the first substrate 3026 of the display panel 302 to complete the assembly.
