The substrate 122 maybe formed of at least one of polyethyleneterephthalate (PET), glass, polycarbonate (PC), and silicon. The substrate 122 maybe a printed circuit board (PCB), on which at least one light assembly 124 is mounted.
The light assembly 124 may be configured as a colored LED emitting at least one of red, green, and blue light or a white LED. The colored LED may include at least one of a redLED, a greenLED, and a blueLED.
The light source included in the light assembly 124 may be a COB(Chip-On-Board) type. The COB light source may have a configuration, in which the LED chip as the light source is directly coupled to the substrate 122. Thus, the process may be simplified. Further, a resistance may be reduced, and a loss of energy resulting from heat may be reduced. Namely, power efficiency of the light assembly 124 may increase. The COB light source can provide the brighter lighting and may be implemented to be thinner and lighter than a related art.
The reflecting sheet 126 may include at least one of metal and metal oxide which are a reflection material. The reflecting sheet 126 may include metal and/or metal oxide having a high reflectance, for example, aluminum (Al), silver (Ag), gold (Au), and titanium dioxide (TiO.sub.2).
The emission layer 135 may be positioned on the substrate 122. The emission layer 135 may emit one of red, green, and blue light. The emission layer 135 may include one of Firpic, (CF3ppy)2Ir(pic), 9,10-di(2-naphthy)anthracene(AND), perylene, distyrybiphenyl, PVK, OXD-7, UGH-3(Blue), and a combination thereof.
As shown in FIG. 12, an angle formed by an extension line from a boundary between the first sheet area 126a and the second sheet area 126b to a boundary between the second sheet area 126b and the third sheet area 126c and two straight lines parallel to the X-axis direction may be called "A". An inclined angle of the second sheet area 126b using an intersection point P between the second sheet area 126b and a straight line of the angle A as a starting point may increase. Namely, an angle of the second sheet area 126b passing the intersection point P in the X-axis direction may sharply increase.
The dot DT may be an area having a pattern different from other areas. The dot DT may be an area of uneven portions (or concave-convex portions)formed on the reflecting sheet 126. The dot DT may be an area, in which at least a portion of the reflecting sheet 126 is colored. For example, the dot DT may be an area of a relatively dark color. For example, the dot DT may be a black or gray area. The dot DT may be an area, in which the uneven portion and the colored portion are mixed with each other. The dot DT may have a geometric shape, in which there is a difference in at least one of a shape, a size, a location, and a color. For example, the dot DT may be one of various shapes including a circle, an oval, a rectangle, a rod, a triangle, etc., formed on the reflecting sheet 126 and/or a combination of the various shapes.
As shown in (a) of FIG. 20, a third ring-shapeddot area CDT3 may be formed in a first lens hole 235 having an overlap shape of circles each having a different radius. For example, the third ring-shapeddot area CDT3 may be formed in a circle having a large second radius R2. For example, the third ring-shapeddot area CDT3 may be formed in at least a portion of the circle having the second radius R2.
As shown in (b) of FIG. 20, when the shape of the first lens hole 235 is changed, a location of the third ring-shapeddot area CDT3 may be changed in accordance with the first lens hole 235.
The third ring-shapeddot area CDT3 shown in (a) of FIG. 20 may be different from the third ring-shapeddot area CDT3 shown in (b) of FIG. 20. For example, a size of the third ring-shapeddot area CDT3 shown in (a) of FIG. 20 may be different from a size of the third ring-shapeddot area CDT3 shown in (b) of FIG. 20. For example, the size of the third ring-shapeddot area CDT3 shown in (a) of FIG. 20 may be larger than the size of the third ring-shapeddot area CDT3 shown in (b) of FIG. 20. The third ring-shapeddot area CDT3 shown in (a) of FIG. 20 may be a dot area corresponding to the horizontal dot area HDA, and the third ring-shapeddot area CDT3 shown in (b) of FIG. 20 may be a dot area corresponding to the vertical dot area VDA. Namely, the size of the third ring-shapeddot area CDT3 formed around the lens hole adjacent to the horizontal dot area HDA may be different from the size of the third ring-shapeddot area CDT3 formed around the lens hole adjacent to the vertical dot area VDA.
The dots included in the third ring-shapeddot area CDT3 may be configured in various combinations. For example, the dots of the third ring-shapeddot area CDT3 may have the same size. For example, the dots of the third ring-shapeddot area CDT3 may include at least two different kinds of dots. For example, as the dot is far away from the lens hole 235, the size of the dot may decrease or increase. For example, a size and/or a kind of the dot in one portion of the third ring-shapeddot area CDT3 may be different from a size and/or a kind of the dot in another portion of the third ring-shapeddot area CDT3.
The first ring-shapeddot area CDT1 may have the shape surrounding the lens hole 235. For example, the first ring-shapeddot area CDT1 may have the shape, in which the dots DT of the same size and/or the same shape surround the lens hole 235. For example, the first ring-shapeddot area CDT1 may have the shape, in which the dots DT, of which at least a partial size and/or shape is different, surround the lens hole 235.
A reflectance of a corresponding area may be changed by the first ring-shapeddot area CDT1. For example, a reflectance of a formation area of the first ring-shapeddot area CDT1 may be reduced. Thus, the first ring-shapeddot area CDT1 may be formed around a specific lens hole 235, which needs to reduce the reflectance.
As shown in FIG. 22, the reflecting sheet 126 may include a plurality of lens holes 235. The first ring-shapeddot area CDT1 may be formed in a specific lens hole 235 among the plurality of lens holes 235. For example, the plurality of lens holes 235 may include a first lens hole 235a, in which the first ring-shapeddot area CDT1 is formed, and a second lens hole 235b, in which the first ring-shapeddot area CDT1 is not formed. The first lens hole 235a having the first ring-shapeddot area CDT1 may be the lens hole 235 positioned on the outside among the plurality of lens holes 235a. Namely, the first ring-shapeddot area CDT1 may be formed in the outermost lens hole 235. This may be because the first lens hole 235a positioned on the outside is close to the bending second sheet area 126b (refer to FIG. 13) of the reflecting sheet 126. Namely, the first ring-shapeddot area CDT1 may be formed in the first lens hole 235a, so as to prevent an excessively large amount of light from being reflected from the second sheet area 126b.
As shown in (a) of FIG. 23, a first ring-shapeddot area CDT1 may be formed around the lens hole 235. The first ring-shapeddot area CDT1 may be dots DT surrounding the lens hole 235. The first ring-shapeddot area CDT1 may be dots DT surrounding the lens hole 235 one time. The dots DT constituting the first ring-shapeddot area CDT1 may have the same size and/or the same shape. Alternatively, at least a portion of the dots DT constituting the first ring-shapeddot area CDT1 may have different sizes and different shapes. For example, a size of the dot DT positioned in the outside direction of the reflecting sheet 126 may be greater than a size of the dot DT positioned in the inside direction of the reflecting sheet 126.
As shown in (b) of FIG. 23, a second ring-shapeddot area CDT2 may be formed around the lens hole 235. The second ring-shapeddot area CDT2 may be dots DT surrounding the lens hole 235 several times (several loops or nested). This is a difference between the first ring-shapeddot area CDT1 surrounding the lens hole 235 one time and the second ring-shapeddot area CDT2.
As shown in (c) of FIG. 23, a third ring-shapeddot area CDT3 may be formed around the lens hole 235. The third ring-shapeddot area CDT3 may be formed around a predetermined portion of the lens hole 235. For example, the third ring-shapeddot area CDT3 may be formed in a portion corresponding to an angle AC in the lens hole 235. The third ring-shapeddot area CDT3 may surround the portion corresponding to the angle AC one time or several times.
As shown in (d) of FIG. 23, a fourth ring-shapeddot area CDT4 may be formed around the lens hole 235. A density of dots of the fourth ring-shapeddot area CDT4 may vary depending on a location. For example, the dots may have the same size, but a distance between the dots may be changed. For example, a distance between the dots positioned close to the lens hole 235 may be relatively short, and a distance between the dots positioned far away from the lens hole 235 may be relatively long.
As shown in (a) of FIG. 24, a fourth ring-shapeddot area CDT4 may be formed around at least a portion of the lens hole 235. The fourth ring-shapeddot area CDT4 may be dots DT positioned in a portion corresponding to an angle AC in the lens hole 235. The fourth ring-shapeddot area CDT4 may be separated from the lens hole 235. Namely, the fourth ring-shapeddot area CDT4 may be formed at a location which is separated from a boundary of the lens hole 235 by a predetermined distance.
As shown in (b) of FIG. 24, a fifth ring-shapeddot area CDT5 may be formed around at least a portion of the lens hole 235. The fifth ring-shapeddot area CDT5 may include a first dot area DT1 and a second dot area DT2. An attribute of a dot constituting the first dot area DT1 may be different from an attribute of a dot constituting the second dot area DT2. For example, sizes of the dots constituting the first and second dot areas DT1 and DT2 may be different from each other. For example, a size of the dot constituting the second dot area DT2 may be greater than a size of the dot constituting the first dot area DT1. An area corresponding to the second dot area DT2 may be an area which can emit a larger amount of light than the lens positioned in the lens hole 235. Thus, the second dot area DT2 may be formed, so as to further reduce a reflectance of the fifth ring-shapeddot area CDT5 than other areas.
A sixth ring-shapeddot area CDT6 may be formed in an area AC. The area AC may be an area having a relatively large radius in the first lens hole 235a. For example, the sixth ring-shapeddot area CDT6 may be formed in an area having a radius R2. An amount of light emitted and/or reflected in a specific direction may be efficiently controlled by the area having the radius R2 and the sixth ring-shapeddot area CDT6.
As shown in (d) of FIG. 24, the lens hole 235 may be a first lens hole 235a, which is not circular. A sixth ring-shapeddot area CDT6 and a seventh ring-shapeddot area CDT7 may be formed around the first lens hole 235a. The sixth ring-shapeddot area CDT6 and the seventh ring-shapeddot area CDT7 may surround the first lens hole 235a.
As shown in FIG. 25, the plurality of lens holes 235 may include first lens holes 235a and second lens holes 235b. A third ring-shapeddot area CDT3 may be formed in the first lens hole 235a. A radius of the first lens hole 235a may be changed. The first lens hole 235a may be positioned on the outside of the plurality of lens holes 235. For example, the first lens hole 235a may be a lens hole 235 positioned in an area close to the long side and/or the short side. For example, the first lens hole 235a may be a lens hole 235 positioned adjacent to a horizontal dot area HDA and/or a vertical dot area VDA. Namely, the third ring-shapeddot area CDT3 may be positioned between the first lens hole 235a and the horizontal dot area HDA and/or the vertical dot area VDA. Thus, an excessively large amount of light may be prevented from being reflected from the second sheet area 126b (refer to FIG. 11) of the reflecting sheet 126.
As shown in (a) of FIG. 30, dots DT may be formed in a predetermined area of the lens hole reflecting sheet 126d. The dots DT may have a configuration corresponding to radial characteristics of the first and second light sources 203a and 203b (refer to FIG. 29). For example, first and second dot areas DTA1 and DTA2 corresponding to the radial direction HA(refer to FIG. 29) may be formed.
A shape of the horizontal dot area HDA may be different from a shape of the vertical dot area VDA. For example, the shape of the horizontal dot area HDA may not be symmetric to the shape of the vertical dot area VDA based on a cutting portion S1 positioned at the corner of the reflecting sheet 126.
FIG. 33 illustrate configuration related to a lens hole of a reflecting sheet according to an example embodiment of the invention
As shown in (a) of FIG. 33, the first lens hole 235a may be a lens hole 235 having a ring-shapeddot area. A location of the first lens hole 235a having the ring-shapeddot area may be different from a location of the second lens hole 235b not having the ring-shapeddot area. For example, the first lens holes 235a may be positioned in the inner area of the reflecting sheet 126, and the second lens holes 235b may be positioned in the outer area of the reflecting sheet 126. The locations of the first and second lens holes 235a and 235b may be changed.
The supporter hole 20 5 may be formed on the reflecting sheet 126. As described above, the supporter hole 205 may have a configuration for the coupling of the supporter 200 (refer to FIG. 10).
As described above, the supporter hole 205 maybe coupled to the supporter 200 (refer to FIG. 10). The supporter 200 may be formed of plastic and/or rubber material. The supporter 200 may reflect at least a portion of light. The reflecting sheet 126 according to the embodiment of the invention may have a dot area DTA in consideration of the reflection of the supporter 200, on which light can be overlappingly concentrated. Namely, the dot area DTA may be formed around the supporter hole 205, so as to reduce an influence of the supporter 200 on the reflection of the reflecting sheet 126.
The embodiments and/or the configurations of the invention may be combined with each other. For example, a configuration "A" described in one embodiment of the invention and the drawings and a configuration "B" described in another embodiment of the invention and the drawings may be combined with each other. Namely, although the combination between the configurations is not directly described, the combination is possible except in the instance where it is described that the combination is impossible. This is certain considering that the embodiment of the invention relates to the display device.
