Embodiment Construction

[0030] Reference herein to "one embodiment" or "an embodiment" refers to a particular feature, structure or characteristic that can be included in at least one implementation of the present invention. "In one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] see figure 1 As shown, it shows a schematic structural diagram of the LED lamp panel of the present invention. As shown in the figure, the LED light board 100 of the present invention is formed by cutting a printed circuit board, which includes several LED light bars 1, and each LED light bar 1 includes a rectangular strip-shaped printed circuit board 11 and is installed on the printed circuit board. The LED lamps 12 on 11 are connected together at one end of each LED lamp bar through a connecting plate 13, and a hollow space 14 is formed between every two LED la...

Abstract

The invention provides an LED (Light-Emitting Diode) lamp panel and a manufacturing method thereof. The method comprises the following steps of: forming an electric conduction trace on a printed circuit board to partition the printed circuit board into a plurality of first LED lamp installation strips arranged side by side and a plurality of second LED lamp installation strips arranged together with the first LED lamp installation strips at intervals; arranging LED lamps on the first LED lamp installation strips and the second LED lamp installation strips; and cutting the printed circuit board into two independent lamp panels.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal display, in particular to the improvement of the structure of the LED lamp board in the backlight module of the liquid crystal display and its manufacturing method. 【Background technique】 [0002] In LCD TVs, computer LCD screens, etc., it is usually necessary to set up a backlight module that provides a light source. The traditional backlight module uses cold cathode tubes as the backlight light source. Now because of the low power consumption and low heat generation of LED lights , high brightness, long life and other characteristics, the backlight module gradually adopts LED lights as the backlight source. [0003] The traditional LED backlight module is to set multiple LED lights on one light bar to act as the light source. In the field of existing LCD TV backlight, the traditional LED backlight uses a single light bar to form the backlight of the entire screen. It is necessary to paste indivi...
