Problems solved by technology

[0006] LED modules arranged in a non-linear circular ring have better brightness and mixed light white purity than LED modules arranged linearly. However, LED modules arranged in a circular ring generally need to Composed of 9 single-color light-emitting diodes, the circuit connection is more complicated and the cost is higher

Abstract

The invention relates to a light-emitting diode module, which comprises: circuit board, five light-emitting diodes as two first color light-emitting diodes, two second color light-emitting diodes and one third color light-emitting diode, wherein the first color light-emitting diodes and the second color light-emitting diodes are rectangle arranged on the circuit board, while same light-emitting diodes are arranged diagonally; the third color light-emitting diode is at the center of rectangle formed by the first color light-emitting diodes and the second colors. The invention also provides one back light system of said light-emitting diodes, with high brightness uniformity and high white purity, with simple process and low cost.

Description

【Technical field】 [0001] The invention relates to a light emitting diode module and a backlight system using the light emitting diode module. 【Background technique】 [0002] At present, liquid crystal materials (Liquid Crystal) without self-luminous properties have been widely used in liquid crystal displays (Liquid Crystal Displays) of different sizes such as televisions, computer screens, liquid crystal projections, mobile phones and personal digital assistants (Personal Digital Assistants, PDAs). LCD), and in order to achieve the purpose of imaging, it must be matched with a light source to illuminate the liquid crystal. Because the backlight is generally placed on the back of the liquid crystal panel, it is called a backlight, and all components including the backlight are called a backlight system. [0003] The backlight system includes a backlight and its optical components. Depending on the position of the backlight, the backlight system can generally be divided into...
