[0041] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model concept should all be considered within the scope of protection claimed by this utility model.

[0042] like Figures 1-8 As shown, this utility model discloses a multi-backlight segment display, comprising:

[0043] The housing 1 has a light-emitting cavity 11 on its front side. A partition 21 protrudes from the light-emitting cavity 11 and divides the light-emitting cavity 11 into a first light-emitting area 111 and a second light-emitting area 112.

[0044] A light guide plate 3 is disposed within the first light-emitting area 111, and a first reflective film 31 is disposed on the rear surface of the light guide plate 3;

[0045] Monochromatic light source 4 is disposed on the outer periphery of light guide plate 3 and emits light towards light guide plate 3;

[0046] Colored light source 5, used to illuminate the second light-emitting area 112;

[0047] The display screen 6 is disposed in the light-emitting cavity 11 and covers the first light-emitting area 111 and the second light-emitting area 112. The display screen 6 has a first display area 61 illuminated by the first light-emitting area 111 and a second display area 62 illuminated by the second light-emitting area 112.

[0048] Therefore, 1. The monochromatic light source 4 illuminates the first luminous area 111, thus enabling the first display area 61 of the display screen 6 to emit light and display. The colored light source 5 illuminates the second luminous area 112, thus enabling the second display area 62 of the display screen 6 to emit light and display. 2. The monochromatic light source 4 uses a constant color to project light from the outer periphery of the light guide plate 3 into the light guide plate 3. The light guide plate 3 and the first reflective film 31 then achieve uniform illumination of the first luminous area 111, and the constant first luminous area 111 displays the constant content on the first display area 61. 3. The colored light source 5 uses a variable color to illuminate the second luminous area 112, and the variable second luminous area 112 displays the variable content on the second display area 62. In summary, the monochromatic light source 4 and the colored light source 5 achieve more diverse display effects.

[0049] The partition 21 is arranged in a square ring shape. The first light-emitting area 111 is located on the outer periphery of the partition 21, and the second light-emitting area 112 is located on the inner periphery of the partition 21. Correspondingly, the light guide plate 3 is provided with a first through hole 33 for the partition 21 to pass through, and the first reflective film 31 is provided with a second through hole 311 for the partition 21 to pass through. The forward-facing area of ​​the first light-emitting area 111 is s1, and the forward-facing area of ​​the second light-emitting area 112 is s2, where s1 > 10 * s2.

[0050] Therefore, by setting a suitable size for the partition 21 to define the required second light-emitting area 112, the first light-emitting area 111, as the main light-emitting area, has a larger area. Thus, the monochromatic light sources 4 arranged on the periphery are uniformly illuminated by the light guide plate 3, which greatly reduces the number of light sources required and reduces the overall power consumption. The second light-emitting area 112, as a special light-emitting area, has a smaller area. Thus, by using a small number of colored light sources 5 to directly illuminate the second light-emitting area 112, the second light-emitting area 112 can be made to emit light uniformly and completely.

[0051] Preferably, there are multiple partitions 21 to form multiple independent second light-emitting areas 112, further optimizing the diversity of the display.

[0052] Specifically, the monochromatic light source 4 is a monochromatic LED light strip, which is used to extend and cover the outer periphery of the light guide plate 3, thereby improving the uniformity of the light source.

[0053] Preferably, the monochromatic light source 4 is a white light source, so that the monochromatic light source 4 emits white light to illuminate the first display area 61 and display the content of the first display area 61.

[0054] Preferably, in this embodiment, there are two monochromatic light sources 4, which are disposed on the left and right sides of the light guide plate 3. In addition, a second reflective film 32 is disposed on the outer periphery of the light guide plate 3, and there are two second reflective films 32, which are disposed on the upper and lower sides of the light guide plate 3.

[0055] Therefore, the two monochromatic light sources 4 emit light on the left and right sides and enter the light guide plate 3. Under the action of the first reflective film 31 and the second reflective film 32, the light in the light guide plate 3 can be efficiently reflected upward to improve the light output brightness of the first light-emitting area 111.

[0056] In addition, an assembly cavity 12 is provided inside the housing 1, and a circuit board 7 is provided inside the assembly cavity 12. The colored light source 5 is disposed on the upper surface of the circuit board 7, so that the colored light source 5 is disposed on the circuit board 7, which not only makes the circuit board 7 more stable, but also makes the overall structure simpler.

[0057] In addition, the housing 1 is provided with a first notch 13 and a second notch 14 that connect the light-emitting cavity 11 and the assembly cavity 12. A first connecting strip 63 passing through the first notch 13 is provided between the display screen 6 and the circuit board 7 to electrically connect the display screen 6 and the circuit board 7. A second connecting strip 41 passing through the second notch 14 is provided between the monochrome light source 4 and the circuit board 7 to electrically connect the monochrome light source 4 and the circuit board 7.

[0058] Furthermore, the housing 1 has a cylindrical cover 22 protruding downwards within the assembly cavity 12. One end of the cover 22 covers the colored light source 5, and the other end connects to the second light-emitting area 112. The cover 22 and the partition 21 combine to form a through-tube structure. This allows the light emitted by the colored light source 5 to pass sequentially through the cover 22 and the second light-emitting area 112 and illuminate the second display area 62.

[0059] Preferably, the front end of the partition 21 abuts against the display screen 6, so that the light from the first light-emitting area 111 is more concentrated on the first display area 61 and the light from the second light-emitting area 112 is more concentrated on the second display area 62.

[0060] Specifically, the housing 1 includes an outer shell 81 and a light guide bracket 82. The light guide bracket 82 is placed on the front side of the outer shell 81 and is fixedly installed by bolts so that the light guide bracket 82 can be removed from the outer shell 81 to open the assembly cavity 12 for disassembly and assembly of the circuit board 7, etc. In addition, the partition 21 and the cover 22 are integrally formed on the light guide bracket 82 to make the overall structure simpler and the production more convenient.

[0061] The first notch 13 and the second notch 14 are also formed on the light guide bracket 82.

[0062] The first display area 61 is printed with a pattern layer, which can be graphics or text of different colors, so that the monochromatic light source 4 provides constant light to the first display area 61, while the pattern layer can display within the required display area; the second display area 62 is colorless and transparent, so that the colored light source 5 provides variable light to the second display area 62, while the colorless and transparent second display area 62 can better display variable light.

[0063] The colored light source 5 can be implemented by using multiple LED beads of different colors arranged close together, so that the light emission of different LED beads or combinations of LED beads can be controlled by the circuit board 7 to emit different colors.

[0064] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
