Description
Technical Field
The present invention relates to a light source of a liquid crystal display, and more particularly, to a reflective plate structure of a light source of a liquid crystal display.
Background
At present, the light emitting source of the notebook computer display adopts the mode of the LED light source, however, the model often causes a series of moire (mura) when the LED light source emits light. For example, when the surface of a frame in which an LED Light source and a Light Guide Plate (LGP) are assembled is deformed and curled outward, the Light source may be emitted from a gap between the frame and the Light guide plate.
In order to avoid the generation of the LED moire as much as possible, one solution is to improve the forming accuracy of the frame itself and improve the assembling capability of an assembling factory. In addition, a white reflecting sheet can be directly adhered to a gap between the frame and the light guide plate so as to block part of light from which the LED light source is to be emitted. However, attaching a white reflector can cause inconvenience to the assembly process, and this technical measure also includes the potential risk of invading the patent of others.
In view of the above, a technical task of designing a reflective plate for shielding a light source of a liquid crystal display is a challenge to be solved by those skilled in the art.

Preferably, the light source of the liquid crystal display is a plurality of LED light sources. Further, an LED light source is fitted through a corresponding opening of the riding part, and one end of the LED light source is in contact with an edge of the light guide plate.
Preferably, the reflection plate is bent in a "U" shape, and a distance between the first and second seam lines is equal to a thickness of the light guide plate. In addition, at least one double-sided adhesive tape is adhered to the surface of the light guide plate, which is attached to the joint portion, and the contact position between the reflection plate and the light guide plate is fixed through the double-sided adhesive tape. According to one embodiment, the number of the double-sided tapes is two, and the double-sided tapes are respectively arranged at two ends of the surface of the light guide plate, which is attached to the joint portion. Wherein, the length of the double-sided tape is the distance between the outward side of the opening and the edge of the seam-riding part.
The reflecting plate for shielding the light source of the liquid crystal display is easily bent into a U shape through the seam-riding part with two seam lines so as to be respectively attached to the upper surface and the lower surface of the light guide plate, further shielding emergent light of the LED light source and avoiding generating LED moire. In addition, a plurality of openings with the same size as the LED light source are formed in the riding seam part, so that the LED light source can be assembled to a preset position through the openings of the reflecting plate.
Drawings
The various aspects of the present invention will become more apparent to the reader after reading the detailed description of the invention with reference to the attached drawings. Wherein,
FIG. 1 is a schematic diagram of a reflective plate for shielding a light source of a liquid crystal display according to an embodiment of the present invention.
Detailed Description
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As described above, in the conventional lcd light source, in order to prevent the LED light source from emitting a part of light from the gap between the frame and the light guide plate, a white reflective sheet is adhered to the gap. However, when the reflective sheet is attached to the upper surface of the light guide plate, it causes inconvenience to the assembly process.
Therefore, the invention designs a reflecting plate with a novel structure, and the detailed description is mainly combined with fig. 1 below. Specifically, fig. 1 is a schematic structural diagram of a reflective plate for shielding a light source of a liquid crystal display according to an embodiment of the present invention. Referring to fig. 1, the reflection plate of the present invention includes a first reflection sheet 10, a second reflection sheet 12, and a crotch portion 14. When assembling, the reflective plate is bent into a "U" shape, wherein the first reflective sheet 10 is attached to the upper surface of the light guide plate of the lcd, and the second reflective sheet 12 is attached to the lower surface of the light guide plate. The seam part 14 has a first seam line 141, a second seam line 142, and a plurality of openings 143, and more specifically, the first seam line 141 is in contact with the first reflective sheet 10, and the second seam line 142 is in contact with the second reflective sheet 12, that is, the first reflective sheet 10 and the seam part 14 are demarcated by the first seam line 141, and the second reflective sheet 12 and the seam part 14 are demarcated by the second seam line 142.
Further, the bezel 14 has a plurality of openings 143, each opening corresponding to each light source of the liquid crystal display, preferably the light sources are LED light sources. Also, in order to improve the performance of the product, the size of the shape of each opening 143 is set to be the same as the size of the corresponding light source. When the reflective plate is bent, since the first reflective sheet 10 and the second reflective sheet 12 are correspondingly attached to the respective surfaces of the light guide plate, the light source may pass through the opening and contact the sidewall of the light guide plate. It should be noted that the reflection plate of the present invention is a one-piece flat plate, and the length of the first reflection sheet 10 is smaller than that of the second reflection sheet 12.
According to an embodiment, in order to attach the first reflective sheet 10 to the upper surface of the light guide plate and the second reflective sheet 12 to the lower surface of the light guide plate as much as possible, the distance between the first and second seam lines 141 and 142 is set to the thickness value of the light guide plate. In addition, in order to enhance the reliable connection between the seam portion 14 of the reflection plate and the side wall of the light guide plate (i.e., the surface of the light guide plate attached to the seam portion 14), at least one double-sided tape (not shown) is adhered to the surface of the light guide plate attached to the seam portion 14, and the contact position between the reflection plate and the light guide plate is fixed by the double-sided tape. Preferably, two double-sided tapes are provided, and each double-sided tape is correspondingly disposed at one end of the surface of the light guide plate attached to the seam portion 14. That is, when the two double-sided tapes are disposed on the side walls of the light guide plate and the reflection plate is bent into a U-shape, the riding part 14 is reliably connected to the light guide plate.
It will be understood by those skilled in the art that the portion of the surface of the light guide plate sidewall corresponding to the opening 143 of the seam 14 will contact the LED after the LED light source is inserted, i.e., the portion of the surface need not be adhered with double-sided adhesive tape. Preferably, the length of the double-sided tape is a distance between an outward side of the opening 143 (i.e., a line on the upper opening 143 in fig. 1) and an edge of the seam-riding part (i.e., an upper edge of the reflection plate in fig. 1).
The reflecting plate for shielding the light source of the liquid crystal display is easily bent into a U shape through the seam-riding part with two seam lines so as to be respectively attached to the upper surface and the lower surface of the light guide plate, further shielding emergent light of the LED light source and avoiding generating LED moire. In addition, a plurality of openings with the same size as the LED light source are formed in the riding seam part, so that the LED light source can be assembled to a preset position through the openings of the reflecting plate.
Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
