Abstract

The invention discloses a backlight module having a light complementary color area. The module is provided with a light guide plate having a light entry side and a light exit side which is vertical to the light entry side, and a linear light source which is adjacent to the light entry side of the light guide plate for irradiating the light entry side and comprises mutually interlaced linearly arranged first wavelength light-emitting diodes and second wavelength light-emitting diodes, wherein the wavelength of the first wavelength light-emitting diode is different from the wavelength of the second wavelength light-emitting diode and the lights form white light beam after being mixed. The module further comprises at least two light complementary color areas at the end or around the side light-emitting diodes so as to uniformly mix the light at the end of the light-emitting diodes. The light complementary color areas complement white light to the end light-emitting diodes. The backlight module having a light complementary color area of the invention can uniformly mix the light beam at the end of the light source.

Description

technical field [0001] The invention relates to the field of a backlight module, in particular to a backlight module with a light complementary color area. Background technique [0002] Today's liquid crystal display (LCD) is more and more widely used, and gradually replaces the traditional cathode ray tube display (CRT display). In comparison, liquid crystal displays have the characteristics of low power consumption, less heat generation, light weight, thin and thin body, and non-radiative properties. Therefore, liquid crystal displays are often used in many modern electronic products, such as notebook computers, monitors, televisions, personal mobile phones or digital assistants (PDAs), and the like. [0003] However, the liquid crystal display itself does not have the function of emitting light, and a backlight module is needed to implement the light emitting function of the liquid crystal display. The structure of the backlight module includes a backplane, a light sour...
