The development of liquid crystal display screens as a main technology for mobile phone display has been receiving attention. Today, improving the display effect of a liquid crystal display is a major development direction of the display industry. The liquid crystal display screen realizes normal display by using the backlight module to provide a light source. The light source realizes the display of the surface light source through the film layers such as the light guide plate. It is common to use phosphors coated with different colors to achieve emission of light of various colors.

Due to the structure of the light source itself, in some cases, the light emitted from the light source may have a color that is not uniform to a desired color after being mixed with the color of the phosphor.

To overcome the problems in the related art, the present disclosure provides a light emitting assembly and a terminal.

The implementation of the present disclosure provides a light emitting assembly comprising: one or more light emitting elements for emitting light and comprising a light emitting surface; the light guide plate comprises a first side and a second side intersected with the first side, and the first side is arranged opposite to the light emitting surface; and a light absorbing layer disposed at the second side of the light guide plate, the light absorbing layer configured to absorb light within a predetermined wavelength range emitted from the light emitting element.

The present disclosure provides a light absorbing layer, and the light absorbing layer may absorb light within a preset wavelength range emitted from a light emitting element. In this case, the light absorbing layer can absorb a certain light within a preset wavelength range, so that the light emitting component can be prevented from emitting too much light within the preset wavelength range, and a better light emitting effect is provided by the light emitting component.

In the disclosure, the light emitting component can be applied to electronic products such as mobile phones, computers, tablet computers, personal digital assistants or wearable electronic devices, and used as a backlight module of the electronic products to provide backlight for a display screen.

Fig. 1 is a schematic structural view of a light emitting element according to an exemplary embodiment. Fig. 2 is a schematic diagram illustrating a structure of a light emitting diode according to an exemplary embodiment. Fig. 3 is a schematic perspective view of a light emitting assembly according to an exemplary embodiment. Fig. 4 is a schematic structural view of a light emitting assembly according to an exemplary embodiment.

As shown in fig. 1 to 4, the light emitting assembly 10 of the present disclosure may include one or more light emitting elements 100, a light guide plate 200, and a light absorbing layer 302. The light emitting element 100 may be configured to emit light, and may include a light emitting surface 101, and the light emitted from the light emitting element 100 may be emitted outward through the light emitting surface 101.

The light emitting element 100 may be a light emitting diode (Light Emitting Diode, LED). The light emitting diode may include a chip 109, the chip 109 may be connected to the first pad 105 through the first gold wire 103, and the chip 109 may be connected to the second pad 106 through the second gold wire 104. The chip 109 may emit blue, red or yellow light.

Brackets 107 may be provided on both sides of the light emitting diode for supporting the housing and internal structure of the light emitting diode. A fluorescent portion 110 is also provided inside the light emitting diode. The fluorescent part 110 may be a yellow phosphor or a red-green phosphor.

In some embodiments, the chip 109 may emit blue light, and the fluorescent part 110 may be coated with yellow phosphor, in which case the light emitting element 100 may emit white light. In some embodiments, the chip 109 may emit yellow light, and the fluorescent part 110 may be coated with red-green phosphor, in which case the light emitting element 100 may emit white light. In some possible embodiments, the chip 109 may emit light of other colors, and the fluorescent portion 110 may also be fluorescent powder of other colors, and may be specifically adjusted according to the color of the light emitted by the light emitting element.

It is to be noted that the light emitting element of the present disclosure is not limited to the LED, but may be other light emitting elements capable of providing a light source.

As shown in fig. 4, the light guide plate 200 may include a first side 211 and a second side 212, and the first side 211 may be opposite to the second side 212. The first side 211 may be opposite to the light emitting element 100, for example, may be disposed opposite to the light emitting surface 101. The light emitted from the light emitting element 100 passes through the light emitting surface 101 and then enters the light guide plate 200, so that the point light source of the light emitting element 100 can be changed into a surface light source by the light guiding effect of the light guide plate 200.

As shown in fig. 4, when the light emitting assembly 10 of the present disclosure is applied to a display device as a backlight module or the like, the third side 213 of the light guide plate 200 may face the display screen, and backlight is provided to the display screen by light emitted from the third side 213 of the light guide plate.

In the present disclosure, the light absorbing layer 302 may be disposed at the second side 212 of the light guide plate, and the light absorbing layer 302 may be configured to absorb light within a predetermined wavelength range emitted from the light emitting element 100. The present disclosure is not limited to a specific range of the predetermined wavelength range, and may be configured to absorb light rays according to manufacturing requirements, specifically, what light rays need to be reduced.

In this case, since the light absorbing layer 302 may absorb light having the first wavelength, light within a predetermined wavelength range among light finally emitted from the entire light emitting assembly 10 may be reduced, i.e., light emitted from the entire light emitting assembly may exhibit a desired color.

In an exemplary embodiment of the present disclosure, the light absorbing layer 302 may be configured as a layer absorbing yellow light, i.e. the light absorbing layer 302 may absorb yellow light, in which case the range of so-called preset wavelengths is 597nm to 577nm. Since the light absorbing layer 302 absorbs a portion of the yellow light, the light emitting component 10 can be prevented from emitting a yellow light, and thus the problem of yellow color of the backlight can be solved.

Note that the present disclosure is not limited thereto, and the light absorbing layer 302 may be configured to absorb red, yellow, blue, and the like, depending on the requirements of the light emitting assembly.

In exemplary embodiments of the present disclosure, the light absorbing layer 302 may be configured as a black layer, i.e., the light absorbing layer 302 may be black. For example, in exemplary embodiments of the present disclosure, the light absorbing layer 302 may include a substrate composed of one or more of polymethyl methacrylate (polymethyl methacrylate, PMMA), polycarbonate (PC), polyethylene terephthalate (Polyethylene terephthalate, PET), polypropylene (PP), polyvinyl chloride (Polyvinyl chloride, PVC), thermoplastic polyurethane elastomer rubber (TPU), polystyrene (PS), polysulfone (PSU); and/or the light-transmitting layer comprises a substrate composed of one or more of polymethyl methacrylate, polycarbonate, polyethylene terephthalate, polypropylene, polyvinyl chloride, thermoplastic polyurethane elastomer rubber, polystyrene and polysulfone.

As shown in fig. 1 and fig. 2, the light emitting surface of an LED lamp can be divided into three parts, namely, left, middle and right parts, and the light emitted from the left and right parts is white and yellow, and the middle part is white and blue, so that the light strip is formed by tens of lamps, yellow light is obviously more than blue light comprehensively, and the light strip is yellow on the backlight.

After the LED is subjected to a centrifugal process, part of fluorescent powder is precipitated on the wall of the cup. The chip emits blue light, the fluorescent powder is excited to generate yellow light, the blue light and the yellow light are mixed to form white light, and the more the quantity of the excited fluorescent powder is, the more the yellow light is. The light rays with small angles are directly emitted after exciting fluorescent powder above the chip; after the light rays with large angles are emitted from the center, fluorescent powder on the periphery of the cup wall is excited again, the quantity of the excited fluorescent powder is large, the yellow light content is large, and the color is relatively yellow.

In one embodiment, the light absorbing layer 302 may be PET. The black light absorbing layer 302 can absorb part of yellow light emitted from the light emitting element 100, and thus can solve the problem of backlight yellowing.

As shown in fig. 3, in an exemplary embodiment of the present disclosure, the light emitting assembly 10 may further include a light transmitting layer 301, and the light transmitting layer 301 may be disposed between the light absorbing layer 302 and the second side 212 of the light guide plate 200. Light emitted from the light emitting element 100 passes through the light transmitting layer 301 to reach the light absorbing layer 302.

In the present disclosure, the light absorbing layer 302 may be disposed such that the light absorbing layer 302 may absorb a range of light within a preset wavelength range, instead of absorbing all light within the preset wavelength range transmitted from the second side 212 of the light guide plate 200. Specifically, in some cases, it is desirable to retain a certain amount of light of the first wavelength, while only a portion of the light within a preset wavelength range needs to be absorbed.

In the present disclosure, the light-transmitting layer 301 may have adhesiveness, and may be, for example, transparent foam or transparent double-sided adhesive tape. Both sides of the light-transmitting layer 301 may be bonded to the light-absorbing layer 302 and the second side 212 of the light guide plate 200, respectively, to fix the light-absorbing layer 302 to the light guide plate 200.

In the present disclosure, the light absorbing layer 302 may also have adhesive properties, such as foam or double sided adhesive. One side of the light absorbing layer 302 is bonded to the light transmitting layer 301.

In an exemplary embodiment of the present disclosure, the light emitting assembly 10 may further include an adhesive member 300, and the adhesive member 300 may include a light absorbing layer 302 and a light transmitting layer 301 adhered to each other. In this case, the original adhesive member in the light emitting module 10 may be configured as the light absorbing layer 302 and the light transmitting layer 301 adhered to each other, so that the arrangement of absorbing light in a predetermined wavelength range may be satisfied without adding additional members.

In the exemplary embodiment of the present disclosure, as shown in fig. 4, the light emitting assembly 10 may further include a circuit board 400, the circuit board 400 being electrically connected with the light emitting element 100, and the on and off of the light emitting element 100 may be controlled by the circuit board 400. The light absorbing layer 302 of the adhesive 300 may be adhered to the circuit board 400. The circuit board 400 and the light guide plate 200 may be fixed to each other by the adhesive member 300.

In an exemplary embodiment of the present disclosure, the adhesive 300 may further include an adhesive layer (not shown), and the light absorbing layer 302 and the light transmitting layer 301 may be adhered to each other by the adhesive layer. For example, an adhesive layer may be disposed between the light absorbing layer 302 and the light transmitting layer 301. However, the present disclosure is not limited thereto and in some embodiments, an adhesive layer may not be provided.

As shown in fig. 5, in an exemplary embodiment of the present disclosure, one or more dots 203 are provided in the light guide plate 200. By providing the dots 203 in the light guide plate 200, the brightness of the light in the light guide plate 200 can be increased, providing a better backlight effect.

As shown in fig. 5, in the exemplary embodiment of the present disclosure, the density of the dots 203 that may be disposed in the first region 220 located at both sides of the light emitting element 100 in the light guide plate 200 may be greater than the density of the dots disposed in the second region 210 of the light guide plate 200 corresponding to the light emitting surface 101 of the light emitting element 100. Thus, the brightness of the first region 220 can be increased, and the problem of light yellowing of the first region 220 can be reduced.

Based on the same concept, the present disclosure also provides a terminal including: the light emitting assembly 10 and the display panel according to any one of the above embodiments, the display panel may be disposed opposite to the light guide plate 200. The light emitting assembly 10 may provide backlight to the display panel, which is located at the rear surface of the display panel. The display panel may have a display surface, i.e., a surface for displaying an image, and a surface opposite to the display surface is a rear surface of the display panel.

The present disclosure provides a light absorbing layer, and the light absorbing layer may absorb light within a preset wavelength range emitted from a light emitting element. Under the condition, the light absorption layer can absorb certain light rays within a preset wavelength range, and the light emitting component can be prevented from emitting excessive light rays within the preset wavelength range, so that the light emitting component provides a better light emitting effect.
