Description

Light source module

The present invention relates to an optical module, and in particular to a light source module.

Generally speaking, direct-lit backlight modules used in flat-panel displays use a two-dimensional array of light-emitting diode panels placed on the back panel of the backlight module, and use the light emitted by the light-emitting diodes (light sources) to match the optical film. and optical plates to produce a uniform light-emitting surface for the backlight module. Specifically, a direct-type backlight module requires an optical distance (OD) between the light source and the optical film. The purpose of this optical distance is to make the light radiated by the light source more uniform. illuminate the optical film.

However, current direct-lit backlight module models cannot meet the brightness ratio requirements of the luminous uniformity test required by automotive standards. Specifically, the current automotive standard luminous uniformity test requires measuring the entire luminous surface of the backlight module (or display) at small unit area measurement points and obtaining the minimum and maximum brightness values of all small unit areas. ratio, and achieve a ratio of more than 80%. However, the current direct-lit backlight module will have dark areas at the corners and edges of the light-emitting surface, resulting in the lowest brightness. The difference between the minimum value and the maximum brightness value is too large to pass the test. However, individually increasing the current of the light-emitting elements in the light-emitting areas located at the corners and edges of the screen can only slightly increase the ratio, but it still cannot meet the vehicle regulations.

In other embodiments , in order to meet different display requirements, the number of the corner setting areas 111C may be less than four), for example, the corner setting area 111C in the lower left corner of the substrate 110 is adjacent to the sides SS3 and SS4. Furthermore, the plurality of light-emitting elements 130 are respectively disposed in the plurality of installation areas 111 and can be used to provide the illumination beam L. Specifically, each setting area 111 corresponds to a light-emitting element 130, and each light-emitting element 130 is arranged, for example, at the geometric center of the respective setting area 111.

Furthermore, as shown in FIG. 1A and FIG. 1B , in this embodiment, the plurality of light-emitting elements 130 include corner light-emitting elements 130C, which are correspondingly provided in each corner setting area 111C. Furthermore, at least one first transparent light guide element 140 is provided in each corner area 111C of the substrate 110, and the corner light emitting element 130C is located between any one of the at least one first transparent light guide element 140 and one side thereof. (for example, the corner light-emitting element 130C is located between the first transparent light guide element 140 and the side SS4, as shown in FIG. 1B). Each first transparent light guide element 140 is a triangular prism transparent light guide element (that is, a columnar element with a triangular cross-section and extending along the normal direction of the parallel cross-section), having a first optical surface OS1, a second optical surface OS2 and The third optical surface OS3, the first optical surface OS1 of the first transparent light guide element 140 faces one of the sides (for example, the side SS4, as shown in FIG. 1B), and the second optical surface OS2 is connected to the third optical surface, for example. Between OS3 and the back plate 110, the first optical surface OS1 is, for example, parallel to the facing side (such as the side SS4, as shown in FIG. 1B). The first optical surface OS1 can be perpendicular to the back plate 110, or relative to the back plate 110. Plate 110 has an inclination angle. As shown in FIG. 1A , in this embodiment, the number of at least one first transparent light guide element 140 in any corner setting area 111C is two, including the first transparent light guide elements 141 and 142 . Taking the corner setting area 111C in the lower left corner of the substrate 110 as an example, the corner light-emitting element 130C is located between the first transparent light guide element 141 and one side SS3, and between the first transparent light guide element 142 and the other side. Between SS4, the first transparent light guide element 141 is connected to the first transparent light guide element 142. As shown in FIG. 1A, the first transparent light guide element 142 is connected to the first transparent light guide element 142, for example. The first optical surface OS1 of a transparent light guide element 141. Specifically, the two first transparent light guide elements 141 and 142 disposed in the corner light-emitting area of the substrate 110 can be integrally formed, or can be two elements that are in contact with each other to form an L-shaped structure. In addition, the first transparent light guide element 140 can be fixed by applying glue on the contact surface with the grille 120 , or by providing a hole on the grille 120 for holding the first transparent light guide element 140 . trench. In another embodiment, the corner setting area 111C may only be provided with the first transparent light guide element 141 or the first transparent light guide element 142 , that is, the number of at least one first transparent light guide element 140 in the corner setting area 111C is one, and the first optical surface OS1 of the first transparent light guide element 140 (for example, the intersection line between the first optical surface OS1 and the back plate 110 ) may be parallel to the facing side (for example, the side SS3 ), or may be parallel to the facing side (for example, the side SS3 ). Both adjacent sides (such as sides SS3 and SS4) have an included angle (such as 45 degrees).

Furthermore, as shown in FIG. 1B , in this embodiment, at least part of the illumination beam L provided by the corner light-emitting element 130C enters the first transparent light guide through the first optical surface OS1 of the first transparent light guide element 140 After the element 140 (the first transparent light guide element 142), it leaves the first transparent light guide element 140 from the first optical surface OS1 through total reflection on the second optical surface OS2 and the third optical surface OS3, and faces it. One of the sides SS4 is transmitted and can be used to compensate the brightness of the corners of the corner setting area 111C of the light source module. Here, at least part of the illumination light beam L is the illumination light beam L incident on the first transparent light guide element 140 at a specific angle (angular range), and because the illumination light beam L is incident on the first transparent light guide element 140 at a specific angle, it passes through The second optical surface OS2 and the third optical surface OS3 form total reflection, and the first transparent The clear light guide element 140 is a light-transmitting material, so part of the illumination beam L incident on the first transparent light guide element 140 can still directly pass through (for example, be refracted rather than totally reflected) the first transparent light guide element 140 and emit light without Affects the optical efficiency of the light source module. Moreover, as shown in FIG. 1B , in addition, at least one optical film FM is disposed above the light-emitting element 130 of the light source module, where the upper surface of the optical film FM is the light-emitting surface of the light source module to adjust the optical module. The light type of the illumination beam L.

In this embodiment, the plurality of setting areas 111 further include an auxiliary setting area 111CS. The auxiliary setting area 111CS is a setting area adjacent to the corner setting area 111C (as shown in FIG. 1A , the number of auxiliary setting areas 111CS is eight), which is only connected to one side and not to other sides. connected setting area. The light source module 100 also includes a second transparent light guide element 150 . In this embodiment, the second transparent light guide element 150 is similar to the first transparent light guide element 140 and is also a triangular prism transparent light guide element having a first optical surface OS1, a second optical surface OS2 and a third optical surface OS3. , and the fixing method of the second transparent light guide element 150 is also similar to that of the first transparent light guide element 140 . However, in this embodiment, the difference between the second transparent light guide element 150 and the first transparent light guide element 140 is that the arrangement area 111 where the second transparent light guide element 150 is located is different from the first transparent light guide element 140 are different, and the size of the second transparent light guide element 150 is smaller than that of the first transparent light guide element 140 . Here, the size may be the size of cross-sectional area or length. For example, the cross-sectional area of the second transparent light guide element 150 is 50% to 80% of the cross-sectional area of the first transparent light guide element 140 .

In detail, the second transparent light guide elements 150 are respectively provided in the auxiliary installation areas 111CS. Furthermore, the light-emitting elements provided in the auxiliary installation area 111CS 130, which is located between the second transparent light guide element 150 and the adjacent corner setting area 111C. It is particularly noted that in other embodiments, the auxiliary setting area is not limited to the setting area adjacent to the corner setting area 111C, but may also include the setting area adjacent to the above-mentioned auxiliary setting area 111CS and only connected to one of the sides. settings area.

Furthermore, as shown in FIG. 1A , in this embodiment, the first optical surface OS1 of the second transparent light guide element 150 faces the plurality of corner setting areas 111C adjacent to the auxiliary setting area 111CS (ie, the closest The corner portion of the second transparent light guide element 150 is provided with an area 111C) and is perpendicular to the nearest side. In this way, as shown in FIGS. 1A and 1B , at least part of the illumination beam L enters the second transparent light guide element 150 through the first optical surface OS1 of the second transparent light guide element 150 , and then passes through the second optical surface OS2 and the third optical surface OS1 . After total reflection on the surface OS3, it leaves the second transparent light guide element 150 from the first optical surface OS1 and passes toward the adjacent (closest) corner setting area 111C. Here, at least part of the illumination beam L is the illumination beam L that is incident on the second transparent light guide element 150 at a specific angle, and because the illumination beam L is incident on the second transparent light guide element 150 at a specific angle, it passes through the second optical surface. Total reflection is formed between OS2 and the third optical surface OS3, so part of the illumination beam L can still emit light directly without affecting the optical efficiency of the light source module.

Moreover, as shown in FIG. 1B , in this embodiment, the height of the grid 120 (for example, the side wall of the grid unit OP) between the second transparent light guide element 150 and the closest first transparent light guide element 140 is less than (eg, between 50% and 80%) the height of the grille 120 (eg, the sidewall of the grille unit OP) located on the side SS4, such that at least part of the illumination beam L is changed by total reflection through the second transparent light guide element 150 That After traveling in the direction, it can be passed to the corner setting area 111C closest to the second transparent light guide element 150 without being blocked by the grille 120, and the light beam L can penetrate the first transparent light guide element 140, which is a light-transmitting element. It can be used to further compensate for the brightness of the adjacent corner setting area 111C.

FIG. 2A is a schematic front view of a light source module of a comparative example. FIG. 2B is a schematic diagram of a simulation of the brightness distribution area of the light-emitting surface of the light source module in FIG. 2A . FIG. 3 is a schematic simulation diagram of the brightness distribution area of the light-emitting surface of the light source module in FIG. 1A . In Figure 2B and Figure 3, the lower the dot density, the brighter the brightness, and the percentage represents the ratio to the maximum brightness, and the light source module is designed as a 5x5 grid as a simulation. As shown in FIG. 2A , the light source module 100 ′ is similar to the light source module 100 of FIG. 1A , but the difference is that the light source module 100 ′ of FIG. 2A does not have the first transparent light guide element 140 and the second transparent light guide element 150 . . Moreover, as shown in Figures 2B and 3, the brightness distribution of the light source module 100' in Figure 2A has obvious dark areas (as shown in Figure 2B, the dense dot area with a brightness lower than 60%), and its small unit area The ratio of the minimum brightness value to the maximum brightness value measured is only about 60%, which cannot meet the vehicle regulations. On the other hand, the brightness distribution of the light source module 100 in Figure 3 has been significantly improved, and can meet the vehicle regulations. The standard ratio of the minimum brightness value to the maximum brightness value measured in a small unit area is 80%.

It can be seen from this that the light source module 100 can reduce dark areas in corners through the arrangement of the first transparent light guide element 140 and the second transparent light guide element 150 and achieve the minimum brightness value measured in a small unit area that complies with vehicle regulations. 80% of the required ratio to the maximum brightness value. Moreover, since the range sizes of the multiple light-emitting areas of the light source module 100 are approximately the same, it is beneficial to subsequent design of the light-emitting areas for local dimming. Certainly. In addition, since the materials of the first transparent light guide element 140 and the second transparent light guide element 150 are transparent, and only the illumination beam L incident on the first transparent light guide element 140 and the second transparent light guide element 150 at a specific angle will form Total reflection leads to the corner area, so most of the illumination beam L can still emit light directly without affecting the optical efficiency of the optical module.

In addition, in this embodiment, the light source module 100 can also be selectively provided with another transparent light guide element, which will be further explained below with reference to FIG. 4 .

Figure 4 is a schematic front view of another light source module according to an embodiment of the present invention. Specifically, in the embodiment of FIG. 4 , the light source module 400 is similar to the light source module 100 of FIG. 1A , and the differences are as follows. In this embodiment, the light source module 400 also has a plurality of third transparent light guide elements 460. The third transparent light guide elements 460 and the second transparent light guide element 150 have the same structure and size, and the third transparent light guide element 460 has the same structure and size as the second transparent light guide element 150. The fixing method of 460 is also similar to the second transparent light guide element 150 . However, as shown in FIG. 4 , the installation area 111 and the installation direction of the third transparent light guide element 460 and the second transparent light guide element 150 are different. Furthermore, in this embodiment, the plurality of setting areas 111 further include an edge setting area 111S. The edge setting area 111S is only connected to one of the sides and is not connected to other sides, nor is it connected to the corner setting area. In the adjacent setting area 111C, the third transparent light guide element 460 is respectively arranged in the edge setting area 111S and the auxiliary setting area 111CS, and in an edge setting area 111S (or the auxiliary setting area 111CS), the light-emitting element 130 is arranged in the third Between the three transparent light guide elements 460 and the adjacent side (eg side SS4). That is, any one of the third transparent light guide elements 460 to any one closest to the third transparent light guide element 460 The shortest distance of one side is greater than the shortest distance from the light-emitting element 130 in the same edge setting area 111S (or the auxiliary setting area 111CS) to one of the sides closest to the third transparent light guide element 460 . Moreover, as shown in FIG. 4 , the first optical surface OS1 of the third transparent light guide element 460 faces one of the sides closest to the third transparent light guide element 460 (for example, the side SS4 ), and at least partially illuminates the light beam L After passing through the third transparent light guide element 460, it is transmitted to one of the sides (for example, side SS4) closest to the third transparent light guide element 460, which can further improve the brightness of the surrounding area of the light source module.

In addition, in this embodiment, the second transparent light guide element 150 and the third transparent light guide element 460 provided in the auxiliary arrangement area 111CS can also be integrally formed to form an L-shaped structure, and the fixing method is, for example, by The contact surface with the grid 120 can be fixed by applying glue, or by providing a groove on the grid 120 for holding the first transparent light guide element 140 .

In this way, through the arrangement of the third transparent light guide element 460, part of the illumination beam L can be further directed to the edge of the substrate 110, thereby further reducing the dark area phenomenon in the surrounding area of the light source module. In addition, since the light source module 400 has a similar structure to the light source module 100 of FIG. 1A, the light source module 400 can also achieve similar functions to the light source module 100 of FIG. 1A, and can achieve similar functions to the light source module 100. The effects and advantages will not be repeated here.

In addition, in the foregoing embodiments, although the light source modules 100 and 400 have a structure with a grille 120 as an example, the invention is not limited to this. In other embodiments, the light source module 100 may not have a structure. The grille 120 may be provided with supports The substrate 110, such that the first transparent light guide element 140, the second transparent light guide element 150 and/or the third transparent light guide element 460 can be supported and fixed on the substrate 110 by the support member of the substrate 110, can achieve the same The light source modules 100 and 400 of the aforementioned embodiments have similar functions and can achieve similar effects and advantages, so they will not be described again here.

To sum up, the embodiments of the present invention have at least one of the following advantages or effects. In the embodiment of the present invention, the light source module can reduce the dark areas in the corners through the arrangement of the first transparent light guide element and the second transparent light guide element, and achieve a brightness measured in a small unit area that meets the vehicle regulations. The ratio of the minimum value to the maximum brightness value is 80% of the requirement. Furthermore, since the range sizes of the multiple light-emitting areas of the light source module are approximately the same, it is advantageous to set the subsequent local dimming light-emitting area. In addition, since the materials of the first transparent light guide element and the second transparent light guide element are transparent, only the illumination beam incident on the first transparent light guide element and the second transparent light guide element at a specific angle will form total reflection and be guided. Corner dark areas, so most of the illumination beam can still emit light directly without affecting the optical efficiency of the optical module.
