Abstract
The utility model relates to a back light source color film, which comprises a good translucent film, wherein, the incidence surface of the film is provided with a fluorescence ink layer, and the incidence surface of the film is smooth or rough. The output surface of the film is smooth or rough. As the incidence surface of the film is provided with the fluorescence ink layer, the fluorescence ink layer has a good transmission performance and improves light transmittance; light utilization ratio is high, so the back light source brightness can achieve the use needs and the energy consumption is low. Furthermore, the utility model has a simple production process, low manufacturing costs, and can be widely used in household appliances, instrumentation, automobile, and other products, in particular to the automobile field, the applications is more extensive to replace the bottom back light, the utility model can greatly reduce costs, save energy, and reduce volume.
Description
Technical field
The utility model relates to a kind of backlight, is meant a kind of variable color film of backlight especially.
Background technology
In the existing backlight, light from 550nm to the 590nm wave band, prior art is difficult to improve its brightness, following several modes commonly used improve brightness: the one, and adopt the end backlight, promptly adopt many lamps below light guide plate, to light, make its brightness improve its shortcoming: be that power consumption is big, cost is high, thickness is thick, lack of homogeneity; The 2nd, adopt white light to light that (brightness of white lamp is very high, as: the LED brightness of a common yellow green 568-572nm can not surpass 100mcd, and a White LED brightness can surpass more than the 1000mcd), film that contains pigment of light guide plate top lid, white light becomes required color when seeing through film, and its shortcoming is: the color of film is dark more, and light transmission is poor more, the utilization factor of light is low, the manufacturing expense height.
The utility model content
Technical problem to be solved in the utility model is: a kind of variable color film of backlight is provided, and it can improve light transmission, the light utilization efficiency height.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of variable color film of backlight, comprise the film that a light transmission is good, and light incident one side surface of described film is provided with a fluorescent ink layer.
Further improvement in the technical proposal is: light incident one side surface of described film is light face or uneven surface.
Further improvement in the technical proposal is: it is light face or uneven surface that the light of described film penetrates a side surface.
The beneficial effects of the utility model are: because light incident one side surface of film is provided with fluorescent ink layer, fluorescent ink layer has extraordinary light transmission, and can improve the optical transmission rate, light utilization efficiency height, back light source brightness can reach use to be needed and less energy consumption; And the utility model manufacture craft is simple, and low cost of manufacture can be widely used on the products such as tame device, instrument and meter, automobile, uses especially extensively at automotive field, is mainly used in that to substitute the end backlight, can reduce cost greatly, and energy efficient reduces volume.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the sectional view of the variable color film of the utility model backlight.
Fig. 2 is the sectional view of second embodiment of the variable color film of the utility model backlight.
Embodiment
As shown in Figure 1, the utility model provides a kind of variable color film of backlight, it comprises the good film of a light transmission 1, light incident one side surface of described film 1 is a light face 10, and another side is a uneven surface 12, and also being provided with a fluorescent ink layer 2 in described light face 10 appearances, the fluorescent ink layer 2 that is adopted adapts and difficult drop-off with the material of film 1.
The utility model also can adopt second embodiment as shown in Figure 2: the two sides of film 1 are uneven surface 12, and are provided with fluorescent ink layer 2 at light incident one side surface of film 1.
In addition, the utility model also can adopt one the 3rd embodiment: the two sides of film 1 are light face 10, and are provided with fluorescent ink layer 2 at light incident one side surface of film 1.
After backlight adopts the utility model variable color film, promptly can adopt white light source, light source carries out leaded light by the site of the light guide plate of backlight, reflectance coating again with white light reflection to the variable color film, white light passes the variable color film just can become the color of 550nm to the light of 590nm wave band, can obtain the light of required color by the color that changes the variable color film.Because light incident one side surface of film 1 is provided with fluorescent ink layer 2, fluorescent ink layer 2 has extraordinary light transmission, and can improve the optical transmission rate, and light utilization efficiency height, back light source brightness can reach use to be needed and less energy consumption.
This product can be widely used on the products such as tame device, instrument and meter, automobile, uses especially extensively at automotive field, is mainly used in that to substitute the end backlight, can reduce cost greatly, and energy efficient reduces volume.
Claims (3)
1, a kind of variable color film of backlight comprises the film that a light transmission is good, it is characterized in that: light incident one side surface of described film is provided with a fluorescent ink layer.
2, the variable color film of backlight as claimed in claim 1 is characterized in that: light incident one side surface of described film is light face or uneven surface.
