[0038] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0042] At present, in the actual operation of the commonly used backlight lamp socket processing solution, due to the superposition of the width tolerance of the black ink silk screen printing of the diffuser and the assembly position tolerance of the diffuser inside the backlight, the black ink often enters the light-emitting area and causes black lines to appear at the lamp socket.
[0043] In order to solve the above problems, the utility model provides a display assembly 100. Figures 3 to 8 This is a specific embodiment of the display assembly provided by the utility model.
[0044] See also Figures 3 to 5 The display component 100 includes a diffuser 1, and the diffuser 1 is provided with a light absorption area 2, and the light absorption area 2 is extended along the length direction of the diffuser 1, wherein the light absorption rate of the diffuser 2 decreases from the bottom thereof and along the width direction of the diffuser 1.
[0045] In the technical solution provided by the utility model, the absorbance of the diffuser 1 close to the backlight source is better than the absorbance far away from the backlight source, that is, the absorbance of the diffuser 1 decreases from its bottom and along the width direction of the diffuser 1. In this way, when the partial absorption area 2 arranged on the diffuser 1 far away from the backlight source enters the backlight luminous area, since the absorbance of the diffuser 1 is relatively weak, even under the influence of the superposition of various tolerances, the partial absorption area 2 will not cause obvious edge black line defects in the backlight luminous area.
[0046] It should be noted that the absorbance of the light absorption zone 2 is a measure of the light intensity reduction caused by the light being absorbed by the light absorption zone 2. The absorbance of the light absorption zone 2 decreases from its bottom and along the width direction of the diffuser 1, which means that the measure of the light intensity reduction caused by the light absorption zone 2 gradually decreases from its bottom and along the width direction of the diffuser 1.
[0047] The calculation formula of absorbance is:
[0048]
[0049] Where A is the absorbance, I 0 is the incident light intensity, I is the transmitted light intensity, ε is the molar absorptivity, c is the concentration of the substance, and l is the optical path distance that light travels through in a solution or solid.
[0050] It can be understood that the light absorption area 2 includes a plurality of inks 21 arranged at intervals along the width direction of the diffuser 1 and the length direction of the diffuser 1, and the lines connecting the geometric centers of the plurality of inks 21 in each row in the length direction of the diffuser 1 are parallel to each other. If the absorbance of the diffuser 1 is to be reduced from its bottom and along the width direction of the diffuser 1, it can be set in a variety of forms. For example, in one embodiment of the present invention, the concentrations of the plurality of inks 21 in each row in the length direction of the diffuser 1 are different, and the concentrations of the plurality of inks 21 are set to decrease successively in the width direction of the diffuser 1. In this way, the absorbance of the light absorption area 2 can be reduced from its bottom along the width direction of the diffuser 1. When the ink 21 in the light absorption area 2 close to the center of the diffuser 1 enters the backlight luminous area, the ink 21 will not cause obvious edge black lines to appear in the backlight luminous area.
[0051] In another embodiment of the utility model, the average distance from the geometric center of the multiple inks 21 in the light absorption area 2 to the boundary of the ink dot decreases from the bottom of the diffuser 1 along the width direction of the diffuser 1. Thus, in this embodiment, the absorbance of each row of the light absorption area 2 in the length direction of the diffuser 1 is positively correlated with the average distance from the geometric center of the corresponding multiple inks 21 to the boundary of the ink dot. Therefore, since the average distance from the geometric center of the multiple inks 21 far from the bottom position of the diffuser 1 to the boundary of the ink dot is the smallest, the absorbance of the light absorption area 2 at this location is also the worst. When this part of the light absorption area 2 enters the backlight luminous area, the ink 21 in this part of the light absorption area 2 will not cause obvious edge black lines to appear in the backlight luminous area.
[0052] In addition, in another embodiment of the utility model, it can be set that the number of the multiple inks 21 in the light absorption area 2 decreases successively from the bottom of the diffuser 1 along the width direction of the diffuser 1. In this way, in this embodiment, the absorbance of each row of the light absorption area 2 in the length direction of the diffuser 1 is positively correlated with the corresponding number of inks 21. Therefore, since the number of inks 21 in the part of the light absorption area 2 far away from the bottom of the diffuser 1 is the least, the absorbance of this part of the light absorption area 2 is also the worst. When the light absorption area 2 in this part enters the backlight luminous area, the ink 21 in this part of the light absorption area 2 will not cause obvious edge black lines to appear in the backlight luminous area.
[0053] Of course, in other embodiments, the average distance and number from the geometric center of the multiple inks 21 in the light absorption area 2 to the ink dot boundary can be reduced successively from the bottom of the diffuser along the width direction of the diffuser 1. At this time, there will be no obvious edge black lines in the backlight luminous area.
[0054] Based on the above content, the present invention does not limit the changing manner of the plurality of inks 21 in the light absorption area 2 from the bottom of the diffusion sheet along the width direction of the diffusion sheet 1 , and it can be selected according to the actual setting.
[0055] It should be noted that the average distance from the geometric center of the ink 21 to the boundary of the ink dot represents the average size of the ink dot. For example, in one embodiment of the present invention, the ink 21 is circular. In this case, the average distance from the geometric center of the ink 21 to the boundary of the ink dot is the radius of the circular ink 21; in another embodiment of the present invention, the ink 21 is rectangular. In this case, the average distance from the geometric center of the ink 21 to the boundary of the ink dot is the average value of the distance from the center of the rectangular ink 21 to each point on the edge line.
[0056] It can be understood that the geometric center of the ink 21 is the central position of the ink 21. For example, when the ink 21 is circular, the geometric center of the ink 21 is the center of the circular ink; when the ink 21 is a parallelogram or a rectangle, the geometric center of the ink 21 is the intersection of the two diagonals of the parallelogram ink or the rectangular ink.
[0057] Of course, the present invention also does not limit the specific shape of the ink 21 , and the shape of each ink 21 can be set to at least one of a circle or a polygon.
[0058] Of course, the shapes of the plurality of inks 21 may also be different, and the present invention does not impose any limitation on this.
[0059] In this embodiment, the shape of the ink 21 is set to be circular.
[0060] Furthermore, the present invention does not limit the average distance from the geometric center of each ink 21 to the boundary of the ink dot. In one embodiment, the average distance from the geometric center of each ink 21 to the boundary of the ink dot is E, |E|≤5.0mm, so as to ensure the uniformity of the absorbance of the absorption zone 2; and in another embodiment, there are differences in the average distances from the geometric centers of the plurality of inks 21 in the absorption zone 2 to the boundary of the ink dot. In this way, the absorption zone 2 can also have good absorbance.
[0061] For details, please see the attached Figures 6 to 7 , by the attached Figures 6 to 7 It is known that in the attached Figure 6 , 7 In the corresponding embodiment, the shape of the ink 21 is set to be circular, and the average distance from the geometric center of the ink 21 to the ink dot boundary is the radius of the circular ink. In other embodiments, when the shape of the ink 21 is set to be rectangular, E is the average distance from the symmetric center point of the rectangular ink to each point on its ink dot boundary.
[0062] In addition, multiple inks 21 are arranged at intervals in the length direction of the diffuser 1, so that the light absorption zone 2 can have a certain absorbance at multiple locations in the length direction of the diffuser 1. It can be understood that in order to make the diffuser 1 have a certain absorbance at multiple locations in the length direction of the diffuser 1 while further improving the uniformity of the absorbance of the light absorption zone 2, in one embodiment, the distance between the geometric centers of two adjacent inks 21 in the light absorption zone 2 in the length direction of the diffuser 1 is A, |A|≤10mm. In this way, the multiple inks 21 within |A|≤10mm are uniformly distributed along the length direction of the diffuser 1 within |A|≤10mm, so that the light absorption zone 2 has a uniform absorbance in the length direction of the diffuser 1, and then the diffuser 1 has a uniform absorbance in the length direction of the diffuser 1, so that it can uniformly absorb the light emitted by the backlight source 400.
[0063] For details, please see the attached Figures 6 to 7 , by the attached Figures 6 to 7 It is known that in the attached Figure 6 , 7 In the corresponding embodiment, the shape of the ink 21 is set to be circular, and the distance between the geometric centers of two adjacent inks 21 in the length direction of the diffuser 1 is the length of the line between the centers of the two adjacent circular inks in the length direction of the diffuser 1. In other embodiments, when the shape of the ink 21 is set to be rectangular, A is the length of the line between the central symmetric points of the two adjacent rectangular inks in the length direction of the diffuser 1.
[0064] Of course, in another embodiment, the distance between two adjacent inks 21 in the light absorption zone 2 in the length direction of the diffuser 1 can also be set to change in sequence. For example, the distance between two adjacent inks 21 in the light absorption zone 2 in the length direction of the diffuser 1 can be set to decrease in sequence along the length direction of the diffuser 1, or can be set to increase in sequence, or can be set to first decrease and then increase, or first increase and then decrease. Such a setting can also enable the light absorption zone 2 to have a certain absorbance at multiple locations in the length direction of the diffuser 1.
[0065] In another embodiment, the distances between two adjacent inks 21 in the light absorption area 2 in the length direction of the diffuser 1 are different from each other. In this case, there is no regularity in the change of the distance between two adjacent inks 21 in the length direction of the diffuser 1. It is only necessary to ensure that the ink 21 is provided at each location of the light absorption area 2 in the length direction of the diffuser 1.
[0066] Of course, in other embodiments, two adjacent inks 21 in the light absorption area 2 in the length direction of the diffusion sheet 1 may also be arranged close to each other.
[0067] Similarly, when only the average distance from the geometric center of the ink 21 to the boundary of the ink dot is changed, there is a gap between two adjacent inks 21 in the width direction of the diffuser 1. The utility model also does not limit the spacing between two adjacent inks 21 in the width direction of the diffuser 1. The distance between the geometric centers of two adjacent inks 21 in the width direction of the diffuser 1 is B, |B|≤10mm. With this arrangement, the distribution of the ink 21 in the light absorption area 2 is sparsely arranged in sequence in the width direction of the diffuser 1, which can ensure that when the multiple inks 21 in the light absorption area 2 close to the center part of the diffuser 1 enter the backlight luminous area, there will be no obvious edge black line defect in the backlight luminous area.
[0068] For details, please see the attached Figures 6 to 7 , in the attached Figure 6 , 7 In the corresponding embodiment, the shape of the ink 21 is set to be circular, and B is the length of the line between the centers of two adjacent circular inks in the width direction of the diffuser 1. In other embodiments, when the shape of the ink 21 is set to be rectangular, B is the length of the line between the central symmetric points of two adjacent rectangular inks in the width direction of the diffuser 1.
[0069] Specifically, in one embodiment, the lines connecting the geometric centers of the multiple inks 21 in each column in the length direction of the diffuser 1 are parallel to each other, and the distance between the geometric centers of two adjacent inks 21 in the width direction of the diffuser 1 is C, |C|≤10mm. With this arrangement, the inks 21 in the light absorption area 2 are sparsely arranged in sequence in the width direction of the diffuser 1, which can ensure that when the multiple inks 21 in the light absorption area 2 close to the center part of the diffuser 1 enter the backlight emitting area, there will be no obvious edge black line defect in the backlight emitting area.
[0070] For details, please see the attached Figure 7 , in the attached Figure 7 In the corresponding embodiment, the shape of the ink 21 is set to be circular, and C is the length of the projection of the line between the centers of two adjacent circular inks in the width direction of the diffuser 1 in the width direction of the diffuser 1. In other embodiments, such as when the shape of the ink 21 is set to be rectangular, C is the length of the projection of the line between the central symmetric points of two adjacent rectangular inks in the width direction of the diffuser 1 in the width direction of the diffuser 1.
[0071] It can be understood that in another embodiment, two adjacent inks 21 in the light absorption area 2 in the width direction of the diffuser 1 correspond to each other, and there is a difference in the distance between the geometric centers of the two corresponding inks 21. For example, the distance between the geometric centers of the corresponding inks 21 can be set to increase or decrease successively in the width direction of the diffuser 1, or it can be set to increase first and then decrease, or first decrease and then increase. Of course, the distance between the geometric centers of the two corresponding inks 21 can also be different from each other. In the actual setting, it can be selected according to the needs.
[0072] In addition, in another embodiment of the present invention, in the light absorption area 2, each row of inks 21 in the width direction of the diffuser 1 and each row of inks 21 in the adjacent row in the width direction of the diffuser 1 may also be staggered, and the present invention does not impose any limitation on this.
[0073] Of course, the present invention does not limit the specific form in which the inks 21 in each row in the width direction of the diffuser 1 are staggered with the inks 21 in an adjacent row in the width direction of the diffuser 1. For example, in one embodiment of the present invention, the line connecting the geometric centers of the inks 21 in each row in the width direction of the diffuser 1 and the inks 21 in an adjacent row is set at an angle to the width direction of the diffuser 1, and the projection of each ink 21 along the width direction of the diffuser 1 is located on the inks 21 in an adjacent row, so that the two inks 21 are partially staggered in the width direction of the diffuser 1.
[0074] In another embodiment of the utility model, in the width direction of the diffuser 1, a line connecting the geometric centers of each ink 21 in each row and each ink 21 in an adjacent row is arranged at an angle with the width direction of the diffuser 1, and a projection of each ink 21 along the width direction of the diffuser 1 is located between two inks 21 in an adjacent row, so that the two inks 21 are completely staggered in the width direction of the diffuser 1.
[0075] It should be noted that, in one embodiment, if the radius of two corresponding adjacent inks 21 in the light absorption zone 2 is not less than the distance between the geometric centers thereof, the inks 21 in the two adjacent light absorption zones 2 are arranged close to each other, or partially overlapped, and as the average distance from the geometric center of the ink 21 in the light absorption zone 2 to the boundary of the ink dot decreases successively in the width direction of the diffuser 1, the radius of the ink 21 in the light absorption zone 2 also decreases accordingly. At this time, there is a distance between the inks 21 in the two adjacent light absorption zones 2.
[0076] Furthermore, the present invention also does not limit the distance between two adjacent inks 21 in the light absorption zone 2 in the width direction of the diffuser 1. For example, in one embodiment, the lines connecting the geometric centers of the multiple inks 21 in each column in the length direction of the diffuser 1 are parallel to each other, and the distance between two adjacent inks 21 in the width direction of the diffuser 1 is D, |D|≤10mm. This arrangement can ensure that the error of the distance between two adjacent inks 21 in the light absorption zone 2 is between -0.1mm and 0.1mm, so that the light absorption zone 2 can have a uniform absorbance. At the same time, since the average distance from the geometric center of the multiple light absorption zones 2 to the boundary of the ink dots decreases successively in the width direction of the diffuser 1, it can also ensure that when the multiple inks 21 in the light absorption zone 2 near the center part of the diffuser 1 enter the backlight emitting area, there will be no obvious edge black line defect in the backlight emitting area.
[0077] It should be noted that the spacing between two adjacent inks 21 is the distance between the two closest points on the boundaries of the ink dots of the two adjacent inks 21 .
[0078] For details, please see the attached Figure 7 , in the attached Figure 7 In the corresponding embodiment, the shape of the ink 21 is set to be circular, and D is the length of the line between a point on the boundary of a circular ink that is closest to another circular ink adjacent in the width direction of the diffuser 1 and a point on the boundary of the other circular ink that is closest to the circular ink. In other embodiments, if the shape of the ink 21 is set to be rectangular, D is the length of the line between any point on a side line of a rectangular ink close to another rectangular ink adjacent in the width direction of the diffuser 1 and a corresponding point on a side line of the other rectangular ink close to the rectangular ink, and the direction of the line between the two points coincides with or is parallel to the width direction of the diffuser 1.
[0079] Of course, in another embodiment, the two adjacent inks 21 in the light absorption area 2 in the width direction of the diffuser 1 correspond to each other, and there is a difference in the spacing between the two corresponding inks 21. For example, the spacing between the two corresponding inks 21 can be set to increase or decrease successively in the width direction of the diffuser 1, or it can be set to increase first and then decrease, or first decrease and then increase. Of course, the spacing between the two corresponding inks 21 can also be different from each other. In the actual setting, it can be selected according to the needs.
[0080] Similarly, in another embodiment, in the light absorption area 2, each row of inks 21 in the width direction of the diffuser 1 and each row of inks 21 in the adjacent row in the width direction of the diffuser 1 may be staggered, and the present invention does not impose any limitation on this.
[0081] Of course, the present invention is also not limited to the specific dislocation form. The inks 21 in each row in the width direction of the diffuser 1 may be partially dislocated or completely dislocated with the inks 21 in the adjacent row in the width direction of the diffuser 1 .
[0082] In addition, the utility model also proposes a display device 1000, comprising a display assembly 100, a light guide plate 200, a reflector plate 300, a backlight source 400, a display screen 500, a film group 600 and a back plate 70. The display assembly 100 is the display assembly 100 described above, the light guide plate 200 is arranged on the side of the light absorption area 2 away from the diffuser 1, the reflector plate 300 is arranged on the side of the light guide plate 200 away from the diffuser 1, the reflector plate 300 can reflect light, the display screen 500 is arranged on the front side of the diffuser 1, the film group 600 is arranged between the diffuser 1 and the display screen 500, and the back plate 700 is arranged on the rear side of the reflector plate 300. The backlight source 400 is arranged at one end of the light guide plate 200 along the width direction of the diffuser 1 and is arranged close to the light absorption area 2, and the backlight source 400 can emit light toward the light guide plate 200.
[0083] It can be understood that the specific structure of the display device 1000 refers to the above embodiment. Since the display device 1000 adopts all the technical solutions of the above embodiment, it also has the beneficial effects brought by the technical solutions of the above embodiment, which will not be described one by one here.
