Light source module and backlight module

Abstract

The invention provides a light source module and a backlight module. The light source module comprises a first substrate, first light sources, a second substrate and second light sources, wherein thefirst substrate is provided with a first surface and a first connecting end; a plurality of first light sources are linearly arranged on the first surface; a first gap is arranged between every two adjacent first light sources; the second substrate is in parallel to the first substrate and is provided with a second surface and a second connecting end, the second surface faces the first surface, and the second connecting end is connected with the first connecting end; a plurality of second light sources are linearly arranged on the second surface; a second gap is arranged between every two adjacent second light sources; at least part of the second light sources respectively extend into the corresponding first gaps; and correspondingly, at least part of the first light sources respectively extend into the corresponding second gaps. By using the invention, when the side length of the effective display area of the panel display is fixed, more light sources can be arranged so as to meet higher requirements for the brightness of the panel display.

Description

technical field [0001] The present invention relates to a light source module and a backlight module using the light source module; specifically, the present invention relates to a light source module structure and a backlight module using the light source module. Background technique [0002] Since the liquid crystal in the liquid crystal display does not emit light itself, a backlight module is usually provided to provide the light source required for display. Currently, the light sources used in the backlight module mainly include light emitting diodes (Light emitting diode, LED) and cold cathode fluorescent lamps (cold cathode fluorescent lamp, CCFL). The selection considerations of the two include factors such as panel size, brightness requirements, and power saving requirements. [0003] figure 1 is a schematic diagram of a known light source module. Such as figure 1 As shown, a common practice is to place a plurality of light emitting diodes 1 on a long substrate ...

AI Technical Summary

Problems solved by technology

However, under the above two prerequisites, the arrangement of LEDs on the substrate has a minimum distance limit; in other words, according to the existing method of linear arrangement, the number of LEDs that can be arranged on the substrate will be limited to a certain number.

[0004] Therefore, for liquid crystal display models with high luminance requirements, especially when the volume is limited, it is difficult to meet the requirements of the general LED arrangement by increasing the number of LEDs.
