Abstract
The utility model relates to an improved structure for the LCD negative phototropic module, which comprises at least a LED that is mounted on the guide rod. The surface of the guide rod is arranged with a blind hole that is used to connect the electric guide pieces used to drive the circuit and the guide rod is provided with a blind hole. The illumination point of the LED is fixed in the blind hole and the illumination is extended to the electric guide at the two sides. Finally epoxy resin is poured around the blind that has undergone the fixation, so as to form the light guide lens, which has the arc profile to ensure that the LED rays diffuse evenly and the LED can form an illuminative surface with even luminance on the LCD.
Description
Technical field
The utility model relates to the backlighting arrangement of a kind of LCD, particularly relates to the backlighting arrangement that a kind of LED of employing is a light source.
Background technology
Present LCD backlighting arrangement mainly is based on white light CCFL (cold cathode fluorescent lamp), and CCFL is arranged on LCD behind, and luminous then projecting on the LCD manifested the picture on the LCD.And more do more greatly in the face of the LCD size, required CCFL and its driving circuit also must increase to some extent.Reach the back lighting function of large-scale LCD, the CCFL of majority must be carried out series/parallel, yet within the range of size of LCD, even the most CCFL of series/parallel, its getable brightness of institute is still not enough, more obvious for large-scale LCD especially.And the CCFL life-span is shorter, adds its comparatively power consumption the related serviceable life that influences LCD, and CCFL contains harmful substances, is undoubtedly a kind of injury for environmental protection.
Therefore, adopt other source backlight, become the inexorable trend of LCD development.Proven technique comparatively at present, for utilizing high-brightness white-light LED as source backlight, LED is applied on the undersized lcd screen for some time, for example on mobile phone, the PDA, more because skill upgrading greatly promotes the brightness of LED, add that weight is light and handy, firm in recent years, and the life-span is longer, so become the alternative of many large-scale LCDs.
General LED is the LED that does not wait in LCD one or both sides device quantity as the method to set up in LCD source backlight, and when power-on, led light source promptly is incident upon on the LCD, and the image on the LCD is manifested.Light and the nonisotropic scattering of general LED, but concentrate on one among a small circle in, using on the LCD of this LED throw light has a zone bright especially, can find out tangible brightness decay around this bright areas.At aforesaid drawbacks, someone adopts intensive laying LED mode, make that the bright scope of any two LEDs is adjacent, reduce dim zone, but so not only cost improves, has increased power consumption, do not have the substance that increases brightness again and help, and the uneven problem of LCD glazed thread still exists, so be not good solution.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of LCD backlight module structure-improved, and employing LED is a light emitting source, and this LED has radian, can guarantee that the light of LED is evenly scattered on the LCD.
Another purpose of the present utility model promptly is to provide a kind of LCD backlight module structure-improved, is light source because of adopting high-brightness white-light LED, and this LCD has high brightness, image quality is good so make, and the advantage of long service life.
Can reach a kind of LCD backlight module structure-improved of above-mentioned utility model purpose, mainly include the LED more than or, this LED is arranged on the guide rod, this guide rod surface is provided with conducting strip, this conducting strip is used for connecting driving circuit, and this guide rod is provided with blind hole, the luminous point of this LED is then solid brilliant in blind hole, and the lead of this luminous point is extended to the conducting strip of both sides, casting epoxy resin forms light guiding lens around the blind hole that solid brilliant routing is finished at last, this light guiding lens has the moulding of radian, with the even scattering of the light of guaranteeing this LED.During use, the light of this luminous point is concentrated via blind hole, and is transmitted on the LCD by the light guiding lens with radian, makes each LED can form the light-emitting area of uniform luminance on LCD, makes LCD seem more comfortable.
The utility model has the advantages that: the light of LED can evenly scatter on the LCD, forms the light-emitting area of uniform luminance, and this LCD has high brightness, image quality is good thereby make, and the advantage of long service life.

Embodiment
See also Fig. 1 to shown in Figure 4, the utility model provides a kind of LCD backlight module structure-improved, this backlight module includes guide rod 2, this guide rod is provided with plural LEDs 1, but make each LED 1 throw light to LCD (scheming not shown), and the light of each LED 1 can be partly overlapping, is distributed in fully on this LCD to guarantee light.
This light guiding lens 13 except aforementioned epoxy resins, also can be the good materials of printing opacity such as glass for having the eyeglass of high transmission rate.
Claims (4)
1. LCD backlight module structure-improved is characterized in that: it is light source that this backlight module adopts LED, and this LED surface setting can evenly scatter to LED light the LCD light guiding lens with radian everywhere.
2. LCD backlight module structure-improved as claimed in claim 1 is characterized in that: wherein said LE D can be provided with more than one.
3. LCD backlight module structure-improved as claimed in claim 1, it is characterized in that: wherein said LED is arranged on the guide rod, this guide rod surface is provided with the conducting strip that is used for connecting driving circuit, guide rod is provided with blind hole, in this blind hole, set firmly the luminous point of described LED, and the lead of this luminous point extended on the conducting strip of both sides, this light guiding lens then cover cap on blind hole.
4. L CD backlight module structure-improved as claimed in claim 1, it is characterized in that: wherein said light guiding lens is the eyeglass of high transmission rate.
