Description of the Invention: TECHNICAL FIELD The present invention relates to a light source. More particularly, the present invention discloses a flicker-free backlight module for use in a display panel that is human-safe, environmentally friendly, and has a very long useful life. [Prior Art] A display panel such as a liquid crystal display (LCD) panel needs to be backlit. This backlight illuminates the liquid crystal display (LCD) from the side or back. This backlight is typically a cold cathode fluorescent tube (CCFL), a hot cathode fluorescent tube (HCFL), an electroluminescent panel (ELP), or an incandescent CCFL backlight is a commonly used source of light. In a fluorescent lamp, the current stimulates the mercury atoms, which causes the mercury atoms to release ultraviolet photons to stimulate the phosphor coating in the tubes. This stimulated phosphor then emits visible light photons. Referring again to Figure 1, a conventional CCFL backlight module is illustrated. As shown in the figure, the conventional CCFL backlight module 1 is composed of a sealed glass tube, which comprises: a small amount of mercury and an inert gas, and has a phosphorus on the inside of the glass tube 11 Powder coating. The electrode is located on the _tube 110. A rubber cover having a winding 112 is attached to: each electrode 120 on both ends of the tube 110; and a winding 112 is attached to the inverter 15A to allow current to flow therethrough to seal the glass tube 110 Turn on. Conventional backlight 100 has a starting voltage greater than 1500 volts and an operating voltage greater than 1 volt. When the alternating current 130 is applied, electrons migrate from one end of the tube 110 to the other via the gas boat. Therefore, this liquid mercury is converted into a gas. The collision of electrons, charged atoms, and mining atoms has caused these electrons to move high energy. After a short period of time, these electrons will return to their original energy level and release photons. The electrons in the fruit atom release photons in the ultraviolet wavelength range, which are invisible to humans. In order to replace the line scale with visible light, the (four) coating is turned out of the lower energy photons. — 3 201044068 Although quite effective, traditional CCFL backlights have several drawbacks. One disadvantage is that this CCFL backlight takes a few seconds to start emitting light. Another disadvantage is that it is difficult to maintain a steady flow of current through the gas, which in some cases can cause the lamp to explode or destroy other components in the circuit. In addition, CCFL backlights require a diffuser to provide uniform light. The ELp backlight must be driven by a fairly high voltage and requires an inverter circuit. Incandescent backlights have a relatively short life span and generate a large amount of heat. The more disadvantage is that the CCFL backlight requires an inverter to provide a voltage of approximately 300 volts used by the CCFL lamp. This light intensity cannot be changed. The cold temperature adversely affects the light output, and the vibration shortens the lamp. The age of use. In addition, the disposal of CCFL backlight modules is problematic due to the waste of their waste. For example, CCFL lamps include small amounts of mercury that are harmful to the environment and human health. Special care must be taken in order to properly dispose of CCFL backlight modules, and special hazardous waste burial must be used. This is not only blameworthy but potentially dangerous and can damage the environment. Therefore, it is necessary to improve the backlight of the display panel to replace the conventional backlight module, and it is economical, effective, and safe for humans and the environment. SUMMARY OF THE INVENTION In order to achieve these and other advantages in accordance with the purpose of the present invention, and to overcome the disadvantages of the conventional methods, the present invention provides an environmentally friendly, flicker-free and safe backlight module as embodied and broadly described herein. It is an object of the present invention to provide a backlight module that replaces the conventional backlight in the display panel. The shimmering backlight of the present invention can be mounted to a conventional county unit towel, so that it is not necessary to replace the backlight unit in order to use the backlight of the present invention. The flicker-free backlight of the present invention replaces CCFL, HCFL, ELP, and white-woven backlights. The backlight of the present invention includes a diffuser tube; a light pipe in the diffuser tube; and a light emitting diode (LED) light source disposed at the end or each end of the k201044068 diffuser tube. In the county (four) of the county system, the money will not flash, the light will not turn on and immediately turn on (tum 〇n). Once the backlight is turned on, the eight can immediately start emitting stable visible light. The backlight module of the present invention does not contain fruit or other harmful materials, and makes the light source easy to dispose of and safe for the environment. Another object of the present invention is to provide a low power tree group which produces a small amount of electricity and has a long limit. The scale of the rider is the owner of the county.

This light from the single-sided LED source supplies light through the two terminals of the connected light pipe 220. Referring to Figure 8F, an exploded view of a flicker-free backlight module including three light pipes and two double-sided LED light sources in accordance with an embodiment of the present invention. 9 201044068 Included in: 2 = said: 2 In the example, the flashless backlight module 200 of the present invention includes a first & 220. In order to provide light to three light pipes, a double-sided L-printing light source 8 is disposed between the first and second light pipes 220, 帛#&f | En f . Between the second and third light pipes 220. The first double-sided light source (10) is set in the other implementation of the fourth (fourth), making more wire and double-sided LED light source. Use more light to extend the length of this _-type backlight module and make the short-sighted light tube and more double-sided LED light source the strength of the field-free back-field group. In the present invention, the first and fourth connectors of such LED light sources are held together by mating with the heat sinks instead of being joined together. It should be noted that the attachment device of the coupler is described as having a hook projection. However, other attachment means can be used in other embodiments of the invention, such as sleeves, thread checks, or pins that are mated to the light pipe. Referring to Figures 9A and 9B, which are alternative light pipe shapes in accordance with an embodiment of the present invention. In such embodiments of the invention, the shape of the light pipe 220 is an alternative shape to the shape illustrated in Figures 1-8. In the previous patch, the filament was a round cylinder in addition to the patterned surface. In the embodiment illustrated in Figures 9A and 9B, the shape of the light pipe 220 is polygonal. By changing the shape of the light pipe, it is possible to influence different light characteristics such as intensity or uniformity. The present invention also provides a backlight module having selective wavelength conversion. The tube is coated with one or several thin layers of visible light transparent material doped with organic dye molecules. This organic dye has strong light absorption characteristics in the ultraviolet (UV) wavelength and in some short wavelength visible spectral regions. When the cover film is irradiated or pumped by the light of the same wavelength (λ 1) via the light pipe, the electrons in the dye molecule jump from the ground state to the excited state of the higher energy level. The decay of these dye molecules from the excited state to the ground state is mainly caused by radiation decay. The wavelength (λ 2) of 201044068 is very strong. Therefore, these dye molecules can be effectively radiated at a pump wavelength (λ υ long. By changing the doping concentration of the dye molecules in this film to become completely opaque or translucent. At this point, no == pump = The light emitted by the light s through the cover film will only be the light of the wavelength λ2. In the case of the daylight, the light covered by the wire will be the light of the combined spectrum of the wavelength λ1 + λ2. Therefore, - Different types of LED light sources can produce different light colors, brightness, or strong

For example, if a blue LED light source is used, this doped coating or doped light pipe can produce a emitted H for down-conversion, this source must have a high energy color, for example: use a blue light with higher energy as the light source , with green red in the doping (due to its lower energy) in order to achieve a down conversion. In one embodiment of the invention, the outer surface of the tube is doped to provide a selected wavelength conversion. In another embodiment of the invention, the light pipe material is doped throughout the material. In one embodiment of the invention, LED light sources of different colors are used.

The reflective coating further enhances the efficiency of the light source by preventing light from escaping or exiting portions of the light pipe. In an embodiment of the invention, power is not constantly supplied. Therefore, the LED is not always on. Since the LED has a fast response time' and the LED can be switched on and off with 201044068 to save power. In this embodiment, the LED is switched on and off at a frequency that is undetectable by the human eye. For example, with a sufficient pulse width to adjust the cycle time function, the light source can not detect a sufficiently high rate of turns on and off (turnsoff) while conserving power. In one embodiment of the invention, the electrical connector of the LED source is compatible with conventional incandescent backlights. In this embodiment, the light pipe cooperates with a diffuser that covers the light pipe to emit uniform light. This embodiment provides an effective replacement for conventional incandescent backlights. The long life and low power of the backlight of the present invention far exceeds that of a typical incandescent backlight, making it more practical and economical.
