Abstract
The utility model discloses a side-in type backlight source structure which comprises a back plate with a backlight cavity, wherein a light reflecting sheet is arranged in the backlight cavity of the back plate, a light guide plate is arranged on the light reflecting sheet, an LED lamp is arranged on one side of the light guide plate, an LED lamp is also arranged on the other side of the light guide plate, the light guide plate is provided with an extending part, the upper side part of the extending part extends towards the direction of the LED lamps on the two sides, and the extending part covers the LED lamps. The lateral backlight source structure can solve the problem that a non-luminous area exists on the upper surface of an LED and realize the ultra-narrow frame.
Description
Technical Field
The utility model belongs to the field of liquid crystal display devices, and particularly relates to a side-in type backlight source structure.
Background
With the continuous development of science and technology, the requirement of consumers on the liquid crystal display industry is higher and higher, and the ultra-narrow (the frame is ultra-narrow) becomes a new development trend of the liquid crystal display industry. In the conventional side-entry LED backlight module product (as shown in fig. 2), a light bar 22 is generally in parallel contact with a light guide plate 21 and is mounted on a back plate 23 having a reflective sheet 24, and since there is a light bar light-emitting structure on the light-entry side and there is a non-light-emitting region on the upper surface of the light bar, the bezel on the light-entry side is too wide, which is urgently needed to be solved.
Disclosure of Invention
In order to solve the problem that the non-light emitting region exists on the upper surface of the LED, a side-in type backlight source structure is provided.
The utility model relates to a side-in type backlight source structure, which comprises a back plate with a backlight cavity, wherein a reflecting sheet is arranged in the backlight cavity of the back plate, a light guide plate is arranged on the reflecting sheet, an LED lamp is arranged on one side of the light guide plate, an LED lamp is also arranged on the other side of the light guide plate, the light guide plate is provided with an extending part, the upper side part of the extending part extends towards the LED lamps on the two sides, and the extending part covers the LED lamps.
In order to conveniently manufacture the backlight source structure, the LED lamp is an LED lamp strip.
In order to make the structure more stable, the extending parts at two sides of the light guide plate are connected with two side walls in the backlight cavity of the back plate.
Has the advantages that: according to the side-in backlight source structure, the LED lamps are arranged on the two sides of the light guide plate, and the upper side part of the light guide plate extends towards the LED lamps on the two sides and covers the LED lamps, so that the problem that no light-emitting area exists on the upper surface of an LED is solved, and an ultra-narrow frame can be realized; the LED lamp is set as the LED lamp strip, so that the backlight source structure is convenient to manufacture; the two side extending parts of the light guide plate are connected with the two side walls in the backlight cavity of the back plate, so that the structure is more stable.
Drawings
FIG. 1 is a schematic structural diagram of a lateral backlight structure according to the present invention;
fig. 2 is a schematic structural diagram of a conventional edge-type backlight structure.
Detailed Description
The technical solution of the present invention is described in detail by the following examples, but the scope of the present invention is not limited to the examples.
Examples
As shown in fig. 1, a side-in type backlight structure includes a back plate 13 having a backlight cavity, a reflector 15 is disposed in the backlight cavity of the back plate, a light guide plate 11 is disposed on the reflector 15, LED light bars 12 in parallel contact with the light guide plate 11 are disposed on two sides of the light guide plate 11, the light guide plate 11 has extending portions 14 extending from an upper side portion to the LED light bars 12 on two sides, the extending portions 14 on two sides cover the LED light bars 12 on two sides, and the extending portions 14 on two sides of the light guide plate 11 are connected to two side walls in the backlight cavity of the back plate.
The above-mentioned techniques not specifically mentioned refer to the prior art.
As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
