Embodiment Construction

[0025] The invention relates to a light source structure of rotating light-emitting diodes and a backlight module using the light source structure. In a preferred embodiment, the light source structure includes a plurality of LED units, such as RGB LED units. However, in other different embodiments, the light source structure may also use LED units arranged in various numbers or in other combinations of different colors. The backlight module provided by the present invention is preferably a direct type backlight module, and the above-mentioned light source structure is arranged inside it. In addition, the present invention can also be a flat display device using the backlight module. The specific embodiments and steps of the present invention will be further described below with reference to the accompanying drawings.

[0026] Figure 3a and Figure 3b Shown is a schematic diagram of the arrangement of multiple LED units in the light source structure of the present inventi...

Abstract

The invention discloses a backlight module which comprises a light source structure, wherein the light source structure is provided with a plurality of Light-Emitting Diode (LED) unit matrixes formed by arranging a plurality of rows and lines of LED units; each LED unit also comprises a plurality of LEDs arranged linearly; in the matrixes, the arrangement direction of adjacent LED units in the same row has one row of angle difference and arrangement direction of adjacent LED units of the same line has one line of angle difference, wherein the LED unit matrixes also comprise a first group of LED units and a second group of LED units; the angle difference of the row or the angle difference of the line of each LED unit in the first group of LED units is a first angle; and in the second groupof LED units, the angle difference of the row or the angle difference of the line of each LED unit is a second angle. The invention effectively improves the problem that the local color of the backlight module is not uniform because the colors of the LEDs are extremely close.

Description

[0001] The present invention is a divisional application. The filing date of the original application is: May 23, 2007; the original application number is: 200710104209.2; the original invention creation name is: light source structure and backlight module using the light source structure. technical field [0002] The invention relates to a backlight module, in particular to a light source structure using a light emitting diode and a backlight module using the light source structure. Background technique [0003] Light-emitting diodes (LEDs) have a wide range of applications, from early mobile communication devices, computer peripheral products and other digital devices, to the emergence of high-brightness light-emitting diodes in recent years, and their applications have also expanded to automobiles, lighting, outdoors, etc. Large display products. Due to the advantages of high color saturation, fast start-up, mercury-free environmental protection, low power consumption and...
