Abstract

The invention discloses a backlight module for a display panel. The backlight module comprises a diffuser, at least one light tube and a single-side light-emitting diode (LED) light source, wherein the at least one light tube is provided with a patterned surface in the diffuser; and the single-side LED light source is attached to each terminal of the diffuser. When a plurality of light tubes are used, the light tubes are connected together by a double-side LED light source. The patterned surfaces of the light tubes are diffused or reflected by rays emitted by the LED light source to provide rays with uniform brightness and intensity. The light tubes are covered by an organic dye molecule doped visible light transparent material of a thin layer. The organic dye has strong ultraviolet light absorption characteristic. By changing the doping concentration of the dye molecules, a coating can become fully opaque or semitransparent for certain wavelengths, and obtains selective wavelength conversion. The mode can change or control color, brightness and intensity of the rays.

Description

technical field [0001] The invention relates to a light source. The present invention more particularly discloses a flicker-free backlight module for a display panel, which is safe for human beings, friendly to the environment, and has a very long service life. Background technique [0002] Display panels such as liquid crystal display (LCD) panels require backlighting. This backlight illuminates the liquid crystal display (LCD) from the side or from behind. This backlight is typically a cold cathode fluorescent lamp (CCFL), a hot cathode fluorescent lamp (HCFL), an electroluminescent panel (ELP), or an incandescent bulb. [0003] A CCFL backlight is a commonly used light source. In a fluorescent lamp, an electric current stimulates the mercury atoms, which causes the mercury atoms to emit ultraviolet photons that stimulate the phosphorous coating in the tube. This stimulated phosphor then emits photons of visible light. [0004] refer to figure 1 , which illustrates a...
