Description
Technical Field
The invention relates to a blue-phase white covering film with high reflectivity.
Background
The reflective film is one of the most important optical films widely used in backlight modules of liquid crystal displays, and the reflective film mainly functions to reflect light rays scattered by a light source to the light emitting direction of a backlight source, so that the light utilization rate is improved, the light loss is reduced, and the purposes of improving the backlight brightness or reducing the power consumption are achieved; the principle of the reflective film is to increase the reflectance by adding particles or generating micropores or bubbles in the reflective film, and utilizing the difference in refractive index between the base resin and the particles or microbubbles.
In order to increase the reflectance of the reflective film, the following method is generally used: a polyester film is added with a large amount of inorganic particles or incompatible resin particles, in the biaxial stretching process, a large amount of micro bubbles are formed by taking the particles as cores, and the light reflectivity is enhanced by utilizing the interface reflection of the inorganic particles or the incompatible resin particles and the light reflection of a micro bubble structure generated by stretching by taking the particles as cores.
However, the addition of a large amount of inorganic particles or incompatible resin particles can seriously affect the mechanical and mechanical properties of the reflective film, so that the reflective film is brittle, a large amount of gaps exist in the reflective film due to a micro-bubble structure formed during stretching of the reflective film, the density of the reflective film is reduced, the stiffness of the reflective film is reduced, and the reflective film is very easy to bend during use.
When the display is used in small-sized displays such as mobile phones, flat panels and the like, the display adopts the bump light guide plates, the reflecting film is thin and has poor stiffness, when the display screen is pressed, the light guide plates extrude the reflecting film, so that the reflecting film and the light guide plates have large deformation, the light reflection is uneven, a white point phenomenon is displayed on the screen, the white point defect is pressed, and the use of the whole backlight module is seriously influenced.
Flexible circuit board (fpc) is indispensable material in electronic products, mainly used in many products such as cell phone, pda, digital camera, etc., fpc flexible printed circuit is a highly reliable and excellent flexible printed circuit made of polyimide or polyester film as base material, white cover film is used in backlight fpc, when led lamp on fpc is lighted, the product can increase backlight brightness and improve uniformity.
With the development of the FPC market, the cover film is endowed with more functions, wherein the blue phase cover film has the characteristics of high reflectivity, cold light source, low transmittance, high temperature resistance, weather resistance and the like, can achieve a shielding effect, and is widely applied to the fields of LED backlight sources and light bars.
The existing white LED light bar circuit board is printed with white oil after being adhered by a white covering film or formed by a light bar circuit board, the white ink is prepared by acrylic acid or polyester modified base, the heat resistance and yellowing resistance of the existing white LED light bar circuit board are poor, and light sources are not concentrated enough to emit; the existing white ink is mainly modified by organic silicon, so that the adhesive force of the ink is low, the ink is easy to fall off when being detected in hundreds of cases, and the adhesive force of the ink is poor.
