Description

Side income formula liquid crystal display backlight lamp strip structure

Technical Field

The utility model relates to the field of television technology, concretely relates to side income formula liquid crystal display backlight bar structure.

Background

With the continuous progress of the display technology of the liquid crystal display television, modern ultrathin liquid crystal display televisions and various liquid crystal display devices mainly adopt side-in type televisions as a main light emitting device, and light bars used by televisions with different sizes are different, so that the light bars are various, and the workload is increased for purchasing and managing.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model provides a side income formula liquid crystal display backlight lamp strip structure can realize that partial big, two kinds of size TV lamp strips mutually use

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

a side-in type liquid crystal display backlight lamp strip structure comprises an aluminum substrate and a plurality of backlight lamp strips; the backlight lamp bars are sequentially fixed on the aluminum substrate and are arranged in a line. The aluminum substrate is used as a base station for fixing the light bar and is also a radiator of the light bar. The aluminum substrate is fixed on the side face of the backlight module, so that the position of the LED lamp strip is fixed.

Furthermore, the backlight lamp bars are connected in series. And sockets are arranged at two ends of each light bar, one end of each light bar is a current input interface a, and the other end of each light bar is a current output interface b. a. And b, the sockets of the two interfaces are respectively a male head and a female head which are matched with each other, and direct connection can be directly realized firstly. A. And the two lamp bars B are connected with the current input interface a of the lamp bar B through the current output interface B of the lamp bar A. The routing of the PCB on each light bar is designed in a series-connection type cascading mode, so that the light bars are connected in pairs.

Furthermore, the backlight lamp bars are connected in parallel. And sockets are arranged at two ends of each light bar, one end of each light bar is a current input interface a, and the other end of each light bar is a current output interface b. a. And b, the sockets of the two interfaces are respectively a male head and a female head which are matched with each other, and direct connection can be directly realized firstly. A. And the two lamp bars B are connected with the current input interface a of the lamp bar B through the current output interface B of the lamp bar A. The routing of the PCB on each light bar is designed in a parallel cascade mode, so that the light bars are connected in pairs.

Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has at least:

can promote in present partial TV and display product, the compatibility is good, can realize the lamp strip and mutually use, practices thrift material management cost, brings more economic benefits for the enterprise.

Drawings

FIG. 1 is a schematic size comparison of 32 inches OC and 65 inches OC;

fig. 2 is a distribution diagram of a modified 32-inch side-entry television light bar and a 65-inch side-entry television light bar;

fig. 3 is a schematic diagram of two segments of light bar circuits after being lapped, and segments 1 and 2 represent each light bar and each LED lamp on the light bar.

Detailed Description

The invention will be further described with reference to an embodiment shown in the drawings.

Take 32 inch lateral TV and 65 inch lateral TV as examples. The size of the 32-inch OC display area is 697.7X 392.3mm, and the size of the 65-inch OC display area is 1436.1X 812.3 mm. The 32 inch length and width dimensions are about one-half of the 65 inch width dimension as viewed from the four-sided dimensions of the display area, see fig. 1. The lamp strip of side income formula TV is directly attached on aluminium base board, and aluminium base board is installed in OC bottom side or left and right sides. The 65 inches side income formula lamp strip can use for 2 inches 32 inches lamp strips, and the lamp pearl parameter of every lamp strip, the distribution of arranging are according to 32 inches side income formula lamp strip designs, have reached the general purpose of 32 inches side income formula module lamp strip and 65 inches side income formula module lamp strip. See figure 2. 2 lamp strips carry out circuit connection through respective head-tail socket, realize parallelly connected on the circuit. The schematic diagram of the circuit connection of the two segments of the light bar is shown in figure 3.

The utility model discloses not only be limited to 2 segmentation lamp strip combinations, can realize the combination of multistage formula lamp strip according to actual need to satisfy bigger size LCD TV.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
