[0057] An electronic device of the present disclosure includes a backlight module. Figure 1 FIG. 1 is a cross-sectional schematic diagram of a backlight module 10 according to an embodiment of the present disclosure. Figure 1 As shown, the backlight module 10 includes a light guide plate 101, a light pattern adjustment component 103 disposed on the light guide plate 101, and a light source 102 disposed on the side of the light guide plate 101. The light source 102 extends, for example, along a first direction (eg Figure 1In some embodiments, the light guide plate 101 may have a light emitting surface 101U, and the light pattern adjustment component 103 is disposed on the light guide plate 101 and adjacent to the light emitting surface 101U of the light guide plate 101. In some embodiments, the backlight module 10 further includes a first optical component 105 and a second optical component 107, the first optical component 105 is disposed on the light pattern adjustment component 103, and the second optical component 107 is disposed on the first optical component 105, but is not limited thereto. In other embodiments (not shown), other layers may be selectively inserted between the light pattern adjustment component 103 and the first optical component 105, or between the first optical component 105 and the second optical component 107. In some embodiments, in the top view direction (e.g., the Z direction), the first optical component 105 is disposed between the light pattern adjustment component 103 and the second optical component 107. In some embodiments, the backlight module 10 may include a reflector 109, which is, for example, disposed below the light guide plate 101. In the top view direction (eg, the Z direction), the light guide plate 101 is disposed between the light pattern adjusting component 103 and the reflective element 109 .

[0058] FIG. 2A to FIG. 2C is an optical analysis diagram of an electronic device according to different embodiments of the present disclosure. Figure 2A It is an optical analysis diagram of an electronic device according to an embodiment of the present disclosure. The backlight module 10 in the electronic device includes, for example, a light guide plate 101, a light source 102, a reflector 109 and a light pattern adjustment component 103, but does not include a first optical component 105 and a second optical component 107. Figure 2B It is an optical analysis diagram of an electronic device according to an embodiment of the present disclosure, wherein the backlight module 10 in the electronic device includes a light guide plate 101, a light source 102, a reflector 109, a light pattern adjustment component 103, and a first optical component 105, but does not include a second optical component 107. Figure 2C 1 is an optical analysis diagram of an electronic device according to an embodiment of the present disclosure, wherein a backlight module 10 in the electronic device comprises a light guide plate 101 , a light source 102 , a reflector 109 , a light pattern adjustment component 103 , a first optical component 105 , and a second optical component 107 . FIG. 2A to FIG. 2C The optical analysis diagram may include an azimuth angle (Ψ) and a tilt angle (θ), wherein the azimuth angle (Ψ) is, for example, from 0 degrees to 360 degrees, and the tilt angle (θ) is, for example, from 0 degrees to 80 degrees, but is not limited thereto. FIG. 2A to FIG. 2C The optical analysis diagram is measured approximately at the center of the electronic device. The azimuth angle (Ψ) is, for example, an angle on the X-direction-Y-direction plane, and the X-direction-Y-direction plane is, for example, equivalent to the plane of the light emitting surface 101U of the light guide plate 101 .

[0059] The azimuth angle of 90 degrees indicates, for example, that the direction of the light source 102 is close to the light source 102 (i.e., corresponding to Figure 1The left half of the angle, the azimuth angle 270 degrees means, for example, the azimuth angle 90 opposite side (i.e. corresponding Figure 1 The inclination angle (θ) is, for example, the inclination angle with the top-view direction (e.g., the Z direction), wherein the inclination angle of 0 degrees is, for example, a direction parallel to the top-view direction (e.g., the Z direction), and a larger inclination angle represents a larger inclination angle with the top-view direction (e.g., the Z direction).

[0060] Depend on Figure 2A It can be seen that the optical analysis diagram of the backlight measured after the light guided from the light guide plate 101 passes through the light pattern adjustment component 103 may have, for example, two large split light packets (e.g., light packet L1 and light packet L2), where light packet L1 corresponds to, for example, a tilt angle of 40 to 70 degrees and an azimuth angle of 300 to 330 degrees, but is not limited thereto. Light packet L2 corresponds to, for example, a tilt angle of 40 to 70 degrees and an azimuth angle of 210 to 240 degrees, but is not limited thereto. The tilt angle and azimuth angle relationship corresponding to the above light packets (light packet L1 and light packet L2)) may be modulated according to the design of the backlight module 10.

[0061] Depend on Figure 2B It can be seen that after the light guided by the light guide plate 101 passes through the light pattern adjustment component 103 and the first optical component 105, for example, the two split light packets (light packet L1 and light packet L2) can be moved to the positive angle (for example, the inclination angle is close to 0 degrees to 30 degrees), that is, the light packets move in the direction of the smaller inclination angle, and the two split light packets (light packet L1 and light packet L2) can be concentrated to form another light packet L3, for example, the light packet L3 roughly corresponds to the inclination angle of 0 degrees to 40 degrees and the azimuth angle of 0 degrees to 360 degrees, but is not limited thereto. The relationship between the inclination angle and the azimuth angle corresponding to the above light packets will be modulated according to the design of the backlight module 10.

[0062] And by Figure 2C It can be further seen that after the light guided from the light guide plate 101 passes through the light pattern adjustment component 103, the first optical component 105 and the second optical component 107, the light packet L3 can be concentrated more toward the positive viewing angle of the electronic device (for example, the inclination angle is close to 0 degrees to 30 degrees), that is, the light packet L3 is concentrated in the direction of the smaller inclination angle, and the light packet L3, for example, roughly corresponds to the inclination angle of 0 degrees to 20 degrees and the azimuth angle of 0 degrees to 360 degrees, but is not limited thereto. The relationship between the inclination angle and the azimuth angle corresponding to the above light packet will be modulated according to the design of the backlight module 10. Since the light packet L3, for example, roughly corresponds to the inclination angle of 0 degrees to 20 degrees and the azimuth angle of 0 degrees to 360 degrees, that is, this backlight module 10 can, for example, provide a larger light packet, when the light emitted by this backlight module 10 is provided to the panel, there is a better visual effect. In addition, the backlight module 10 including the light pattern adjusting component 103, the first optical component 105, and the second optical component 107 can provide a light brightness effect with high contrast and / or high positive viewing angle.

[0063] The following combination Figure 1 The structures of the first optical component 105 and the second optical component 107 in the backlight module 10 are further described in detail.

[0064] like Figure 1 As shown, the first optical component 105 includes a first side 105B adjacent to the light guide plate 101 and a second side 105U away from the light guide plate 101. In some embodiments, the first optical component 105 may include a plurality of first prism structures 1051, and the plurality of first prism structures 1051 are, for example, disposed on the second side 105U of the first optical component 105. The first prism structure 1051 has a prism structure (for example, a positive prism structure) protruding in a direction away from the light guide plate 101, and the prism structure 1051 extends, for example, along a second direction, and the second direction may be parallel to the first direction (for example Figure 1 X direction) are the same or different.

[0065] like Figure 1 As shown, the second optical component 107 includes a first side 107B adjacent to the light guide plate 101 and a second side 107U away from the light guide plate 101. In some embodiments, the second optical component 107 may include a plurality of second prism structures 1071, and the second prism structures 1071 are, for example, disposed on the second side 107U of the second optical component 107, but are not limited thereto. In some embodiments, the second optical component 107 has a plurality of second prism structures (e.g., regular prism structures) protruding in a direction away from the light guide plate 101. In some embodiments, the second prism structures 1071 extend, for example, along a third direction, and the extension direction (e.g., the second direction) of one of the plurality of first prism structures 1051 may be different from the extension direction (e.g., the third direction) of one of the plurality of second prism structures 1071. In some embodiments, the extension direction (e.g., the second direction) of the first prism structure 1051 is, for example, perpendicular to the extension direction (e.g., the third direction) of the second prism structure 1071. In some embodiments, the included angle between the extension direction of the first prism structure 1051 and the extension direction of the second prism structure 1071 is, for example, between 60 degrees and 90 degrees (60 degrees≦included angle≦90 degrees).

[0068] Reference Figure 1 , the light pattern adjustment component 103 includes a first side 103B adjacent to the light guide plate 101 and a second side 103U away from the light guide plate 101. In some embodiments, the first side 103B may have a plurality of prism structures 1033.

In some embodiments, the plurality of structural units 1031 may be recessed structures recessed toward the light guide plate 101, such as Figure 4 As shown, but not limited to.

[0069] The following takes the structural unit 1031 as an example of a protruding structure protruding in a direction away from the light guide plate 101. Figure 5 and Figure 6 The structural unit 1031 is described.

In some embodiments, in the top view direction of the electronic device, the contour of the bottom surface 1031B of the structure unit 1031 may have various shapes. In some embodiments, as shown in FIG. Figure 5 As shown in (a), in the top view direction of the electronic device, the outline of the bottom surface 1031B of the structure unit 1031 may have a square or rectangular shape (including a rectangle, a diamond, but not limited thereto), but is not limited thereto. Figure 6 As shown in FIG. 5( a ), in the top view of the electronic device, the bottom surface 1031B of the structure unit 1031 may have an elliptical, circular or other suitable shapes.

[0071] In some embodiments, the projection of the vertex 1031T of the structure unit 1031 on the bottom surface 1031B is defined as the center point C of the bottom surface 1031B.

In some embodiments, the maximum length L of the bottom surface 1031B passing through the center point C may be, for example, greater than or equal to 0 and less than or equal to 80 μm. In some embodiments, the height H of the structure unit 1031 is, for example, less than or equal to 50 μm, that is, in the top view direction (for example, the Z direction), the vertical distance between the bottom surface 1031B and the vertex 1031T of the structure unit 1031 may be less than or equal to 50 μm.

In some embodiments, the plurality of structural units 1031 are arranged adjacent to each other, for example, and the plurality of structural units 1031 are arranged in a closely adjacent manner (i.e., there is no gap between the plurality of structural units 1031), but the invention is not limited thereto. In other embodiments (not shown), the plurality of structural units 1031 are arranged with gaps between them, for example, but the invention is not limited thereto. In some embodiments (e.g., the plurality of structural units 1031 may be arranged regularly or irregularly. Figure 5 (a)), a plurality of structural units 1031 are arranged into a plurality of structural unit rows, for example, along an arrangement direction AR. Figure 5 (a) is an example of one column, but there are actually more columns. In some embodiments (such as Figure 3 (b)), the multiple structural units 1031 in two adjacent columns of the multiple structural unit columns 1031L may be, for example, offset from each other. In some embodiments, the connection direction of the center points C of the multiple structural units 1031 in one structural unit column 1031L may be defined as the arrangement direction AR of the multiple structural units 1031.

The fourth direction may be the same as or different from the first direction, the second direction and / or the third direction. In some embodiments (such as Figure 5 (a)), the angle α between the arrangement direction AR of the plurality of structural units 1031 in one of the plurality of structural unit columns 1031L and the extension direction (e.g., Y direction) of one of the plurality of prism structures 1033 is, for example, in the range of 10 to 80° (10°≦angle α≦80°), but is not limited thereto.

In other words, in the cross-sectional direction of the electronic device, the side surface 1031S of the structure unit 1031 connects the intersection 1031C of the bottom surface 1031B and the vertex 1031T of the structure unit 1031.
