Embodiment Construction

[0132] The invention discloses a light emitting diode light source module and its application on a backlight module and a liquid crystal display. In order to make the narration of the present invention more detailed and complete, refer to the following description and cooperate Figure 2A to Figure 10 attached drawings.

[0133] In the application of a large-scale display, since the signal driving input terminals required by the light emitting diode light bar 102 will be greatly increased, in order to accommodate more signal driving input terminals on the limited setting space of the surface 106 of the printed circuit board 106, it is necessary Reduce the spacing between signal drive input terminals. Therefore, the width of the signal driving input terminal of the light emitting diode light bar 102 usually also needs to be reduced accordingly, so that the bonding force between the connecting wire 112 of the driving signal input device 108 and the signal driving input terminal...

Abstract

The invention relates to a light source module with light emitting diodes and application thereof. The light source module of the light emitting diode at least comprises a circuit board which is provided with opposite first and second surfaces, wherein the circuit board at least comprises a plurality of signal driving input terminals which are arranged on the second surface; and a plurality of light emitting diodes which are arranged on the first surface of the circuit board and are at least connected with the signal driving input terminals partially and electrically.

Description

technical field [0001] The present invention relates to a light source module, and in particular to a light emitting diode (LED) light source module and its application on a backlight module and a liquid crystal display (LCD). Background technique [0002] With the vigorous development of light emitting diode technology, and the application of light emitting diodes in backlight modules of liquid crystal displays, which has the advantages of thinning and power saving, the application of light emitting diodes in liquid crystal displays has attracted much attention. However, various problems arising from the application of light-emitting diodes on the backlight module greatly slow down the speed of mass adoption of light-emitting diodes in liquid crystal displays. [0003] One of the problems arising from the application of LEDs is the joint stability of the driving signal input device of the LED light bar module. Please refer to figure 1 , which is a schematic top view of a ...
