Description
Technical field
The utility model relates to a kind of backlight, relates in particular to a kind of high brightness ultra-thin type backlight.
Background technology
Backlight is to be positioned at LCDs a kind of light source behind, and its illumination effect will directly have influence on the visual effect of LCDs.LCDs itself is not luminous, and its display graphics or character are its results to light modulation.
In the design of backlight, selecting of light source used is very important.Light source used has determined the photoelectric parameters such as the power consumption, brightness, color of backlight, has also determined the characteristics such as its service condition and service life.
LED(light emitting diode) there is life-span length, low heating, but its brightness is lower.
Linear light source CCFL(cold cathode fluorescent tube) brightness high, the life-span is long.
Flat light source VFD(flat fluorescent lamp) high, the good uniformity of brightness.
When backlight is applied on cell phone apparatus, under the irradiation of outdoor sunburst, have the low shortcoming of brightness, cannot see display screen clearly, and then cause cannot operating handset, had a strong impact on the user of mobile phone is experienced.
LGP plays the effect that point, line and area source is changed into area source.
Utility model content
(1) technical problem that will solve
The utility model is in order to overcome the shortcoming that existing back light source brightness is lower, and the technical problems to be solved in the utility model is to provide a kind of high brightness ultra-thin type backlight.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides so a kind of high brightness ultra-thin type backlight, include LGP, point source of light, linear light source and flat light source, described point source of light is arranged on the rear side of described LGP, described linear light source is arranged on the front side of described LGP, described area source be arranged on described LGP under.
Preferably, described point source of light is light emitting diode, and described linear light source is cold cathode fluorescent tube, and described flat light source is flat fluorescent lamp.
Preferably, also be provided with oblique incidence formula line source on the right side of described LGP, described oblique incidence formula line source is cold cathode fluorescent tube, and the incidence angle that the light that described oblique incidence formula line source penetrates is injected described LGP is 10 degree, 15 degree, 18 degree, 25 degree or 30 degree.
